    Despite the increasing attention on the therapeutic potential of Curcuma longa (turmeric), the biological activities of curcuminoids other than curcumin are not well understood. Here, we investigated antivasoconstrictive activities of C. longa extract and its ingredients using freshly isolated rat aortic rings. C. longa extract significantly suppressed agonist-stimulated vasoconstriction, and cyclocurcumin was found to be the most potent (IC 50 against phenylephrine-induced vasoconstriction: 14.9 ± 1.0 μM) among the 10 tested ingredients including four curcuminoids. Cyclocurcumin significantly inhibited contraction of vascular smooth muscle, which was mediated by the suppression of myosin-light-chain phosphorylation and calcium influx via the L-type calcium channel. The inhibitory effect of cyclocurcumin was observed to be reversible and without cytotoxicity. Taken together, we demonstrated that cyclocurcumin, a bioactive ingredient in C. longa, may have a therapeutic potential as a novel antivasoconstrictive natural product.

    Full Text Available The aim of this review paper is to explore the available information from research findings on the use of Turmeric (Curcuma longa as a reliable phytogenic antibiotic for poultry production in the tropics especially in Nigeria and other countries. A wide range of phytogenic additives has found a growing interest in fortification of poultry diets. Supplementation of natural alternatives to antibiotic growth promoters in order to maintain both birds’ performance and health in the tropics will be a welcome development. Turmeric has reportedly been widely supplemented in poultry diets as natural alternative antibiotics in several studies with outstanding performances. The nutritional, medicinal, haematological and phyto-toxicological effects of turmeric were reviewed in this paper. Hence, turmeric supplementation at recommended inclusion rate in poultry feeds without posing any deleterious effects to the birds’ performances as well as the consumers of the products, and ultimately, leading to better profitability on the part of the farmers, will be a nutritional breakthrough for the farmers in the tropics.

    Full Text Available We investigated the aqueous and ethanolic extracts of different forms (local names: mura and chora of turmeric (Curcuma longa from the Khulna and Chittagong divisions of Bangladesh for their antioxidant properties and polyphenol, flavonoid, tannin, and ascorbic acid contents. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl (DPPH free radical-scavenging activity and ferric reducing antioxidant power (FRAP values. The ethanolic extract of Chittagong’s mura contained the highest concentrations of polyphenols (16.07%, flavonoids (9.66%, and ascorbic acid (0.09 mg/100 g and chora resulted in high yields (17.39%. The ethanolic extract of Khulna’s mura showed a higher DPPH radical-scavenging activity with the lowest 50% inhibitory concentration (IC50 (1.08 μg/mL, while Khulna’s chora had the highest FRAP value (4204.46±74.48 μM Fe [II] per 100 g. Overall, the ethanolic extract had higher antioxidant properties than those in the aqueous extract. However, the tannin concentration was lower in the ethanolic extract. We conclude that the turmeric varieties investigated in this study are useful sources of natural antioxidants, which confer significant protection against free radical damage.

    Curcumin (diferuloyl methane) is the main bioactive component of turmeric (Curcuma longa L.) having remarkable multipotent medicinal and therapeutic applications. Two Bacilli isolated from termitarium soil and identified as Bacillus endophyticus TSH42 and Bacillus cereus TSH77 were used for bacterization of rhizome for raising C. longa ver. suguna for growth and enhancement. Both the strains showed remarkable PGP activities and also chemotactic in nature with high chemotactic index. Turmeric plants bacterized with strains B. endophyticus TSH42 and B. cereus TSH77 individually and in combination increased plant growth and turmeric production up to 18% in field trial in comparison to non-bacterized plants. High-performance liquid chromatography analysis was performed to determine the content of curcumin, which showed concentration of curcumin in un-inoculated turmeric as 3.66 g which increased by 13.6% (4.16 g) when combination of TSH42 and TSH77 was used.

    The phytochemical composition and antioxidant capacities of 6 new NRCRI turmeric (Curcuma longa L.) accessions (39, 35, 60, 30, 50 and 41) were determined using standard techniques. The moisture contents of the tumeric samples ranged from 15.75 to 47.80% and the curcumin contents of the turmeric samples fell within the range of curcumin obtained from turmeric in other countries of the world. Furthermore, the turmeric accessions contained considerable amounts of antioxidants (measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and reducing power assays), alkaloids, flavonoids, anthocyanins, and phenolics. There was significant correlation between the anthocyanin contents of the tumeric accessions versus their alkaloid (0.744) and flavonoid contents (0.986) suggesting an additive effect between the anthocyanins and alkaloids in turmeric; significant correlation between the inhibition of the turmeric accessions on DPPH radical versus their flavonoid (0.892) and anthocyanin (0.949) contents and significant correlation between the reducing power of the turmeric accessions versus their flavonoid (0.973) and anthocyanin (0.974) contents suggesting that anthocyanins as flavonoids largely contribute to the antioxidant activities of turmeric. The positive regression recorded between inhibition of DPPH radical by the turmeric accessions and quercetin versus reducing power (R2 = 0.852) suggest that any of these methods could be used to assess the antioxidant activities of tumeric. Finally, the study indicated the potentials of the turmeric accessions especially accessions 30 and 50 as promising sources of antioxidants.

    Turmeric (Curcuma longa), an important asexually reproducing spice crop of the family Zingiberaceae is highly susceptible to bacterial and fungal pathogens. The identification of resistance gene analogs holds great promise for development of resistant turmeric cultivars. Degenerate primers designed based on known resistance genes (R-genes) were used in combinations to elucidate resistance gene analogs from Curcuma longa cultivar surama. The three primers resulted in amplicons with expected sizes of 450-600 bp. The nucleotide sequence of these amplicons was obtained through sequencing; their predicted amino acid sequences compared to each other and to the amino acid sequences of known R-genes revealed significant sequence similarity. The finding of conserved domains, viz., kinase-1a, kinase-2 and hydrophobic motif, provided evidence that the sequences belong to the NBS-LRR class gene family. The presence of tryptophan as the last residue of kinase-2 motif further qualified them to be in the non-TIR-NBS-LRR subfamily of resistance genes. A cluster analysis based on the neighbor-joining method was carried out using Curcuma NBS analogs together with several resistance gene analogs and known R-genes, which classified them into two distinct subclasses, corresponding to clades N3 and N4 of non-TIR-NBS sequences described in plants. The NBS analogs that we isolated can be used as guidelines to eventually isolate numerous R-genes in turmeric.

    Curcuma longa L., commonly known as turmeric, is one of the economically and medicinally important plant species. It is predominantly cultivated in the tropical and sub tropical countries. India is the largest producer, and exporter of turmeric in the world, followed by China, Indonesia, Bangladesh and Thailand. In the present study, Directed Amplification of Minisatellite DNA (DAMD) and Inter Simple Sequence Repeats (ISSR), methods were used to estimate the genetic variability in indigenous turmeric germplasm. Cumulative data analysis for DAMD (15) and ISSR (13) markers resulted into 478 fragments, out of which 392 fragments were polymorphic, revealing 82 % polymorphism across the turmeric genotypes. Wide range of pairwise genetic distances (0.03-0.59) across the genotypes revealed that these genotypes are genetically quite diverse. The UPGMA dendrogram generated using cumulative data showed significant relationships amongst the genotypes. All 29 genotypes studied grouped into two clusters irrespective of their geographical affiliations with 100 % bootstrap value except few genotypes, suggesting considerable diversity amongst the genotypes. These results suggested that the current collection of turmeric genotypes preserve the vast majority of natural variations. The results further demonstrate the efficiency and reliability of DAMD and ISSR markers in determining the genetic diversity and relationships among the indigenous turmeric germplasm. DAMD and ISSR profiling have identified diverse turmeric genotypes, which could be further utilized in various genetic improvement programmes including conventional as well as marker assisted breeding towards development of new and desirable turmeric genotypes.

    Structural and spectral properties of curcumin and metal- curcumin complex derived from turmeric (Curcuma longa) were studied by SEM and vibrational (FTIR and Raman) techniques. By comparison between curcumin commercial, fresh turmeric and a yellow powder obtained via extraction and purification of turmeric, we have found that this insoluble powder in water is curcumin. The yellow compound could complex with certain ion metal and this metal-curcumin coloring complex is water soluble and capable of producing varying hues of the same colors and having antimicrobial, cytotoxicity activities for use in foodstuffs and pharmacy. The result also demonstrates that Micro-Raman spec-troscopy is a valuable non-destructive tool and fast for investigation of a natural plant even when occurring in low concentrations.

    Turmeric (Curcuma longa L., Zingiberaceae) rhizomes contain two classes of secondary metabolites, curcuminoids and the less well-studied essential oils. Having previously identified potent anti-arthritic effects of the curcuminoids in turmeric extracts in an animal model of rheumatoid arthritis (RA), studies were undertaken to determine whether the turmeric essential oils (TEO) were also joint protective using the same experimental model. Crude or refined TEO extracts dramatically inhibited joint swelling (90-100% inhibition) in female rats with streptococcal cell wall (SCW)-induced arthritis when extracts were administered via intraperitoneal injection to maximize uniform delivery. However, this anti-arthritic effect was accompanied by significant morbidity and mortality. Oral administration of a 20-fold higher dose TEO was nontoxic, but only mildly joint-protective (20% inhibition). These results do not support the isolated use of TEO for arthritis treatment but, instead, identify potential safety concerns in vertebrates exposed to TEO.

    Curcumin is the major constituent of turmeric (Curcuma longa). Turmeric has been widely used as a spice in foods and for therapeutic applications such as anti-inflammatory, antihyperlipidemic, and antimicrobial activities. Turmeric and curcumin are nonmutagenic and nongenotoxic. Oral use of turmeric and curcumin did not have reproductive toxicity in animals at certain doses. Studies on human did not show toxic effects, and curcumin was safe at the dose of 6 g/day orally for 4-7 weeks. However, some adverse effects such as gastrointestinal upsets may occur. Moreover, oral bioavailable formulations of curcumin were safe for human at the dose of 500 mg two times in a day for 30 days, but there are still few trials and more studies are needed specially on nanoformulations and it should be discussed in a separate article. In addition, curcumin is known as a generally recognized as safe substance. This review discusses the safety and toxicity of turmeric and curcumin in medicine. Turmeric and curcumin are nontoxic for human especially in oral administration. Turmeric and curcumin are also safe in animals. They are nonmutagenic and are safe in pregnancy in animals but more studies in human are needed. Copyright © 2018 John Wiley & Sons, Ltd.

    Curcuma longa L. or turmeric of the family Zingiberaceae is widely used in Thai traditional medicines for the treatment of rash, itching, tinea, and ringworm. Previous studies on turmeric oil reported effective antifungal activity against dermatophytes, a group of fungi that causes skin diseases. In this study, turmeric creams containing 6 and 10% w/w turmeric oil were prepared and tested against clinical strains of dermatophytes using broth dilution technique. Minimum fungicidal concentrations of 6 and 10% w/w turmeric creams were found to be 312  μ g/mL. Ar-turmerone, a major compound separated from turmeric oil, promoted more effective antidermatophytic activity with the MICs of 1.56-6.25  μ g/mL, compared to 3.90-7.81  μ g/mL of standard ketoconazole. The results indicated that 6% w/w turmeric oil in the cream was suitable to be formulated as antidermatophytic preparation. Further research should be done on long-term chemical and antifungal stabilities of the preparation.

    Turmeric (Curcuma longa), a commonly used spice throughout the world, has been shown to exhibit antiinflammatory, antimicrobial, antioxidant, and anti-neoplastic properties. Growing evidence shows that an active component of turmeric, curcumin, may be used medically to treat a variety of dermatologic diseases. This systematic review was conducted to examine the evidence for the use of both topical and ingested turmeric/curcumin to modulate skin health and function. The PubMed and Embase databases were systematically searched for clinical studies involving humans that examined the relationship between products containing turmeric, curcumin, and skin health. A total of 234 articles were uncovered, and a total of 18 studies met inclusion criteria. Nine studies evaluated the effects of ingestion, eight studies evaluated the effects of topical, and one study evaluated the effects of both ingested and topical application of turmeric/curcumin. Skin conditions examined include acne, alopecia, atopic dermatitis, facial photoaging, oral lichen planus, pruritus, psoriasis, radiodermatitis, and vitiligo. Ten studies noted statistically significant improvement in skin disease severity in the turmeric/curcumin treatment groups compared with control groups. Overall, there is early evidence that turmeric/curcumin products and supplements, both oral and topical, may provide therapeutic benefits for skin health. However, currently published studies are limited and further studies will be essential to better evaluate efficacy and the mechanisms involved. Copyright © 2016 John Wiley & Sons, Ltd.

    The turmeric (Curcuma longa L. rhizomes) EtOH extract significantly suppressed an increase in blood glucose level in type 2 diabetic KK-A(y) mice. In an in vitro evaluation, the extract stimulated human adipocyte differentiation in a dose-dependent manner and showed human peroxisome proliferator-activated receptor (PPAR)-gamma ligand-binding activity in a GAL4-PPAR-gamma chimera assay. The main constituents of the extract were identified as curcumin, demethoxycurcumin, bisdemethoxycurcumin, and ar-turmerone, which had also PPAR-gamma ligand-binding activity. These results indicate that turmeric is a promising ingredient of functional food for the prevention and/or amelioration of type 2 diabetes and that curcumin, demethoxycurcumin, bisdemethoxycurcumin, and ar-turmerone mainly contribute to the effects via PPAR-gamma activation.

    Curcumin, desmethoxycurcumin and bisdesmethoxycurcumin are bioactive constituents of turmeric (Curcuma longa). Owing to their different potency, quality control of turmeric based on the content of each curcuminoid is more reliable than that based on total curcuminoids. However, to perform such an assay, high-cost instrument is needed. To develop a simple and low-cost method for the simultaneous quantification of three curcuminoids in turmeric using TLC and the public-domain software Scion Image. The image of a TLC chromatogram of turmeric extract was recorded using a digital scanner. The density of the TLC spot of each curcuminoid was analysed by the Scion Image software. The density value was transformed to concentration by comparison with the calibration curve of standard curcuminoids developed on the same TLC plate. The polynomial regression data for all curcuminoids showed good linear relationship with R(2) > 0.99 in the concentration range of 0.375-6 microg/spot. The limits of detection and quantitation were 43-73 and 143-242 ng/spot, respectively. The method gave adequate precision, accuracy and recovery. The contents of each curcuminoid determined using this method were not significantly different from those determined using the TLC densitometric method. TLC image analysis using Scion Image is shown to be a reliable method for the simultaneous analysis of the content of each curcuminoid in turmeric.

    Turmeric belongs to the ginger family Zingiberaceae. Currently, cheminformatics approaches are not employed in any of the spices to study the medicinal properties traditionally attributed to them. The aim of this study is to find the most efficacious molecule which does not have any toxic effects. In the present study, toxicity of 200 chemical compounds from turmeric were predicted (includes bacterial mutagenicity, rodent carcinogenicity and human hepatotoxicity). The study shows out of 200 compounds, 184 compounds were predicted as toxigenic, 136 compounds are mutagenic, 153 compounds are carcinogenic and 64 compounds are hepatotoxic. To cross validate our results, we have chosen the popular curcumin and found that curcumin and its derivatives may cause dose dependent hepatotoxicity. The results of these studies indicate that, in contrast to curcumin, few other compounds in turmeric which are non-mutagenic, non-carcinogenic, non-hepatotoxic, and do not have any side-effects. Hence, the cost-effective approach presented in this paper could be used to filter toxic compounds from the drug discovery lifecycle. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

The second sample (control group was stored at 4 ºC for 48 hours and turmeric at 1% (w/w was added to the third sample, which was homogenized and then stored under the same conditions as the second sample. E. coli and S. aureus were enumerated in all samples. Mean bacterial counts determined for the control samples and for the samples with turmeric addition after 48h of storage were 1.83 x 10(4 CFU g-1 and 1.80 x 10(4 CFU g-1 for S. aureus, and 9.36 x 10³ CFU g-1 and 7.25 x 10³ CFU g-1 for E. coli, respectively. The results showed that there was no significant reduction in bacterial counts with the addition of 1% turmeric to chicken breast meat.

    Turmeric (Curcuma longa) is a type of herb belonging to ginger family, which is widely grown in southern and south western tropical Asia region. Turmeric, which has an importance place in the cuisines of Iran, Malesia, India, China, Polynesia, and Thailand, is often used as spice and has an effect on the nature, color, and taste of foods. Turmeric is also known to have been used for centuries in India and China for the medical treatments of illnesses such as dermatologic diseases, infection, stress, and depression. Turmeric's effects on health are generally centered upon an orange-yellow colored, lipophilic polyphenol substance called "curcumin," which is acquired from the rhizomes of the herb. Curcumin is known recently to have antioxidant, anti-inflammatory, anticancer effects and, thanks to these effects, to have an important role in prevention and treatment of various illnesses ranging notably from cancer to autoimmune, neurological, cardiovascular diseases, and diabetic. Furthermore, it is aimed to increase the biological activity and physiological effects of the curcumin on the body by synthesizing curcumin analogues. This article reviews the history, chemical and physical features, analogues, metabolites, mechanisms of its physiological activities, and effects on health of curcumin.

    Curcuma longa (Zingiberaceae) is known for its uses in medicine, cosmetics, food flavouring and textile industries. The secondary metabolites of turmeric like essential oil, oleoresin and curcumin are important for its multipurpose uses. These traits of turmeric vary from place to place due to the influence of environment, soil and agro-climatic conditions. Here, we analyzed turmeric from different agroclimatic regions for influence of various factors on its growth and yield of important phytochemicals. A high curcumin yielding cultivar i.e., Roma was collected from high altitude research station, Koraput (HARS) and planted in nine agroclimatic regions of Odisha. Analysis of soil texture, pH, organic carbon, micro and macro nutrients were done from all the studied zones up to 2nd generation. Plants grown in their released station i.e., Eastern Ghat High Land showed 5% of curcumin and were taken as control. Plants grown in different agroclimatic zones showed a range of 1.4-5% of curcumin and 0.3-0.7% of rhizome essential oil and 0.3-1% of leaf essential oil content. Gas chromatography and mass spectra analysis showed tumerone and alpha phellandrene as the major compounds in all the zones with 10-20% variation. The present study will be immensely helpful for standardization and management of environmental and ecological factors for high phytochemical yield in turmeric plant.

    The physico-chemical, oxidative and sensory characteristics of fried rice snack, yukwa with different amounts of turmeric powder (Curcuma longa) were investigated. The moisture content of the pallet ranged from 16.47% to 19.84%. After frying the pallet, a slight decrease in the degree of expansion was obtained with increasing turmeric powder content. The textural properties of yukwa were not changed until the turmeric powder content reached 5%; however, over 8% addition induced a decrease in the hardness and an increase in the crispiness. Oxidative deterioration was effectively inhibited by turmeric powder addition, and more turmeric powder in yukwa led to higher free radical scavenging activity. Based on the sensory characteristics, a 5% addition of turmeric powder was the most acceptable for the yukwa product. In the correlation results among variables, the moisture content of the pallet proved to be the most important factor for yukwa quality. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Anti-diabetic capacity of Curcuma longa volatile oil in terms of its ability to inhibit glucosidase activities was evaluated. Turmeric volatile oils inhibited glucosidase enzymes more effectively than the reference standard drug acarbose. Drying of rhizomes was found to enhance α-glucosidase (IC₅₀ = 1.32-0.38 μg/ml) and α-amylase (IC₅₀ = 64.7-34.3 μg/ml) inhibitory capacities of volatile oils. Ar-Turmerone, the major volatile component in the rhizome also showed potent α-glucosidase (IC₅₀ = 0.28 μg) and α-amylase (IC₅₀ = 24.5 μg) inhibition.

    Turmeric (Curcuma longa) is a triploid, vegetatively propagated crop introduced early during the colonization of Brazil. Turmeric rhizomes are ground into a powder used as a natural dye in the food industry, although recent research suggests a greater potential for the development of drugs and cosmetics. In Brazil, little is known about the genetic variability available for crop improvement. We examined the genetic diversity among turmeric accessions from a Brazilian germplasm collection comprising 39 accessions collected from the States of Goiás, Mato Grosso do Sul, Minas Gerais, São Paulo, and Pará. For comparison, 18 additional genotypes were analyzed, including samples from India and Puerto Rico. Total DNA was extracted from lyophilized leaf tissue and genetic analysis was performed using 17 microsatellite markers (single-sequence repeats). Shannon-Weiner indexes ranged from 0.017 (Minas Gerais) to 0.316 (São Paulo). Analyses of molecular variance (AMOVA) demonstrated major differences between countries (63.4%) and that most of the genetic diversity in Brazil is found within states (75.3%). Genotypes from São Paulo State were the most divergent and potentially useful for crop improvement. Structure analysis indicated two main groups of accessions. These results can help target future collecting efforts for introduction of new materials needed to develop more productive and better adapted cultivars.

    The aim of the present study was to assess the potential chemopreventive effects of myrrh (Commiphora molmol) vs. turmeric (Curcuma longa) in hepatocarcinogenic rats induced by a single intraperitoneal injection of diethylnitrosamine (DENA) (200 mg/kg body weight). Ninety male Wistar rats used in this study were randomly divided into six equal groups (n=15). Group 1 rats served as negative controls; group 2 received a single i.p. injection of DENA and served as positive controls. Rats in both groups were fed on basal diet. Group 3 rats were fed a diet containing 5% turmeric, whereas group 4 rats were fed a diet containing 2% myrrh. Rats in groups 5 and 6 received a single i.p. injection of DENA and were fed diets containing 5% turmeric and 2% myrrh, respectively. The study demonstrated that DENA caused a significant increase in serum indices of liver enzymes and also severe histological and immunohistochemical changes in hepatic tissues. These included disorganized hepatic parenchyma, appearance of pseudoacinar and trabecular arrays of hepatocytes and alterations in CD10-immunoreactivity. Dietary supplementation of turmeric relatively improved the biochemical parameters to values approximating those of the negative controls and delayed the initiation of carcinogenesis. In contrast, myrrh did not improve the biochemical parameters or delay the hepatocarcinogenesis. Both turmeric and myrrh induced significant biochemical and histological changes in non-treated rats. In conclusion, DENA significantly changes the biological enzymatic activities in serum and the integrity of hepatic tissues. Phytochemicals with potential hepatoprotective effects must be applied cautiously owing to their potential hepatotoxicity. Copyright © 2011 Elsevier GmbH. All rights reserved.

    Expressed sequence tags (ESTs) from turmeric (Curcuma longa L.) were used for the screening of type and frequency of Class I (hypervariable) simple sequence repeats (SSRs). A total of 231 microsatellite repeats were detected from 12,593 EST sequences of turmeric after redundancy elimination. The average density of Class I SSRs accounts to one SSR per 17.96 kb of EST. Mononucleotides were the most abundant class of microsatellite repeat in turmeric ESTs followed by trinucleotides. A robust set of 17 polymorphic EST-SSRs were developed and used for evaluating 20 turmeric accessions. The number of alleles detected ranged from 3 to 8 per loci. The developed markers were also evaluated in 13 related species of C. longa confirming high rate (100%) of cross species transferability. The polymorphic microsatellite markers generated from this study could be used for genetic diversity analysis and resolving the taxonomic confusion prevailing in the genus.

    Hand-foot syndrome (HFS) is common and frequently occurs in the first cycle of treatment in approximately 40% to 50% of patients who receive capecitabine. Turmeric (Curcuma longa) is a plant used in Ayurvedic medicine with clinical activity in various inflammatory conditions. Our objective was to evaluate whether turmeric was active for the prevention of capecitabine-induced HFS. We included patients older than 18 years of age without previous exposure to capecitabine who were scheduled to receive this medication. Before starting treatment, after three weeks and at the end of six weeks, we evaluated dermatologic toxicity, conducted quality-of-life questionnaires (EORTC-QLQC30 and DLQI) and collected serum inflammatory biomarkers (inerleukin-6 (IL-6), tumor necrosis factor-a (TNF-a), C-reactive protein (CRP), and albumin). We administered turmeric at a dose of 4 g/day (2 pills 12 hours apart) starting at the beginning of capecitabine treatment and lasting six weeks. We included 40 patients whose mean age was 62 years. Most were female (80%), 52% had breast cancer, and 47.5% had GI tumors. After the first cycle of capecitabine treatment, we observed that 11 of 40 patients developed HFS (27.5%; 95% CI [15, 42]), whereas four patients developed HFS equal or superior to grade 2 (10%; 95% CI [3.3, 23]). We did not find any correlations between the inflammatory markers tested and HFS. We show that turmeric combined with capecitabine seems to produce a lower rate of HFS, especially grade 2 or higher. These findings need to be reproduced in larger controlled studies.

    Turmeric (Curcuma longa L.) is a perennial rhizomatous plant from the family of Zingibraceae, native in South Asia. The main components of turmeric are curcuminoids and essential oil which are responsible for turmeric characteristic such as odor and taste. Due to the large areas of saline land in Iran and less information related to cultivation of turmeric, in this research, the effect of salinity on growth, curcumin and essential oil of turmeric was evaluated. Rhizomes were planted in coco peat and perlite for germination. Then uniform germinated rhizomes transferred to hydroponic condition containing Hoagland's solution. Two months old plants were exposed to salinity (0, 20, 60 and 100 mM NaCl) for two months via hydroponic media using Hoagland's solution. Then dry weight of different plant parts, chlorophyll, curcumin and essential oil components of turmeric were determined. The result indicated that, dry weight reductions in 100 mM NaCl were 191%, 141%, 56%, 30% in leaf, pseudo-stem, root and rhizome, respectively (This is almost equal to 6.9, 2.87, 0.34 and 0.23 mg plant(-1) mM(-1)NaCl reduction of dry weight, respectively). The reductions in chlorophyll a and b are almost 3.32 and 0.79 μg/gFW respectively due to one unit addition of NaCl (P curcumin of rhizome for four months old plant versus three months were almost 5 fold for 0 mM NaCl and 2 fold for 100 mM NaCl due to one month of delay in harvest. Low salinity has positive effect in curcumin production but higher salinity (higher than 60 mM) had adverse effect and causes 24% reduction of curcumin compared to control plants. There were more para-cymene and terpineol in volatile oils of turmeric rhizome than the other components, most of the volatile oil compounds were unchanged or varied slightly as salinity changed.

    Full Text Available Turmeric (Curcuma longa L. is a medicinal plant that is commonly used as spice and preservative. Many types of endophytic fungi have been reported as being associated with medicinal plants and able to synthesize secondary metabolites. In this study, endophytic fungi were isolated from all plant parts of turmeric plants. Identification of the endophytic fungi was done using morphological characteristics and sequencing of the internal transcribed spacer (ITS region of ribosomal DNA. The dual culture method was used for screening antibacterial activity of the endophytic fungi against Morganella morganii, a common histamine-producing bacteria. The disc diffusion method was used to test the ability of water fractions of selected endophytic fungi to inhibit M. morganii growth. Two-dimensional thin layer chromatography was used to determine the fungal extract inhibition activity on histamine formation. In total, 11 endophytic fungi were successfully isolated and identified as Arthrobotrys foliicola, Cochliobolus kusanoi, Daldinia eschscholzii, Fusarium oxysporum, Fusarium proliferatum, Fusarium solani, Fusarium verticillioides, Phanerochaete chrysosporium, and Phaeosphaeria ammophilae. Five isolates showed inhibition activity against M. morganii in the dual culture tests. Based on the disc diffusion assay, A. foliicola and F. verticillioides inhibited the growth of M. morganii as a histamine-producing bacteria, and inhibiting histamine formation in fish. The best effects in inhibiting growth of the histamine-producing bacteria and histamine formation inhibition in fish were produced with F. verticillioides water fraction at 0°C incubation.

    Iron overload disorders may be treated by chelation therapy. This study describes a novel method for isolating iron chelators from complex mixtures including plant extracts. We demonstrate the one-step isolation of curcuminoids from turmeric, the medicinal food spice derived from Curcuma longa. The method uses iron-nitrilotriacetic acid (NTA)-agarose, to which curcumin binds rapidly, specifically, and reversibly. Curcumin, demethoxycurcumin, and bisdemethoxycurcumin each bound iron-NTA-agarose with comparable affinities and a stoichiometry near 1. Analyses of binding efficiencies and purity demonstrated that curcuminoids comprise the primary iron binding compounds recovered from a crude turmeric extract. Competition of curcuminoid binding to the iron resin was used to characterize the metal binding site on curcumin and to detect iron binding by added chelators. Curcumin-Iron-NTA-agarose binding was inhibited by other metals with relative potency: (>90% inhibition) Cu 2+  ~ Al 3+  > Zn 2+  ≥ Ca 2+  ~ Mg 2+  ~ Mn 2+ (80% by addition of iron to the media; uptake was completely restored by desferoxamine. Ranking of metals by relative potencies for blocking curcumin uptake agreed with their relative potencies in blocking curcumin binding to iron-NTA-agarose. We conclude that curcumin can selectively bind toxic metals including iron in a physiological setting, and propose inhibition of curcumin binding to iron-NTA-agarose for iron chelator screening.

    Curcumin is the major active ingredient of Curcuma longa L. , traditionally known as turmeric and has been shown to exhibit a wide range of pharmacological activities including anti-parasitic effect. However, it is found to be water-insoluble and has low bioavailability. The aim of this study was to explore the potential role of turmeric solved in olive oil either alone or in combination with praziquantel (PZQ) in treatment of schistosomiasis mansoni . The whole turmeric powder suspended in olive oil (as a solvent) is indicated to S. mansoni -infected mice aiming to study its potential therapeutic role, either alone or in combination with PZQ. Turmeric significantly reduced S. mansoni worm burden and complete absence of adult worms achieved in mice treated with combination of turmeric and PZQ. Turmeric has slight non-significant effect on the oogram pattern in all examined S. mansoni infected mice. Turmeric and PZQ found to exert a significant reduction of granuloma size in comparison with control. However, turmeric has a non-significant effect on granuloma number. On the other hand, turmeric or/and PZQ treated mice showed obvious improvement of pathology with mild cloudy swelling and less hydropic degeneration. Turmeric significantly reduced parasite worm burden, granuloma size and consequently the pathology of affected liver, it still far less effective than PZQ.

    Chronic hyperglycaemia in diabetes leads to the overproduction of free radicals and evidence is increasing that these contribute to the development of diabetic nephropathy. Among the spices, turmeric (Curcuma longa) is used as a flavouring and colouring agent in the indian diet every day and is known to possess anti-oxidant properties. The present study was designed to examine the effect of curcumin, a yellow pigment of turmeric, on renal function and oxidative stress in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced by a single intraperitoneal injection of STZ (65 mg/kg) in rats. Four weeks after STZ injection, rats were divided into four groups, namely control rats, diabetic rats and diabetic rats treated with curcumin (15 and 30 mg/kg, p.o.) for 2 weeks. Renal function was assessed by creatinine, blood urea nitrogen, creatinine and urea clearance and urine albumin excretion. Oxidative stress was measured by renal malonaldehyde, reduced glutathione and the anti-oxidant enzymes superoxide dismutase and catalase. Streptozotocin-injected rats showed significant increases in blood glucose, polyuria and a decrease in bodyweight compared with age-matched control rats. After 6 weeks, diabetic rats also exhibited renal dysfunction, as evidenced by reduced creatinine and urea clearance and proteinuria, along with a marked increase in oxidative stress, as determined by lipid peroxidation and activities of key anti-oxidant enzymes. Chronic treatment with curcumin significantly attenuated both renal dysfunction and oxidative stress in diabetic rats. These results provide confirmatory evidence of oxidative stress in diabetic nephropathy and point towards the possible anti-oxidative mechanism being responsible for the nephroprotective action of curcumin.

    Curcuma longa has well-known insecticidal and repellent effects on insect pests, but its impact on Trichoplusia ni is unknown. In this study, the compound ar-turmerone, extracted and purified from C. longa rhizomes, was identified, and its insecticidal effects, along with turmeric powder, curcuminoid pigments and crude essential oil were evaluated against this important agricultural pest. The role of natural (sesamol and piperonal) and synthetic [piperonyl butoxide (PBO)] synergists under laboratory and greenhouse conditions were also evaluated. The concentration of ar-turmerone in C. longa rhizomes harvested was 0.32% (dwt). Turmeric powder and its derivatives caused 10-20% mortality in third instar T. ni at a very low dose (10 μg/larva). Addition of PBO increased toxicity of turmeric powder and its derivatives (90-97% mortality) in most binary combinations (5 μg of turmeric powder or its derivatives +5 μg of PBO), but neither piperonal nor sesamol were active as synergists. The compound ar-turmerone alone and the combination with PBO reduced larval weight on treated Brassica oleracea in the laboratory and in greenhouse experiments, compared with the negative control. The compound ar-turmerone could be used as a low cost botanical insecticide for integrated management of cabbage looper in vegetable production.

    Turmeric (Curcuma longa L., family Zingiberaceae) is one of the most economically important plants for its use in food, medicine, and cosmetic industries. Cultivar identification is a major constraint in turmeric, owing to high degree of morphological similarity that in turn, affects its commercialization. The present study addresses this constraint, using EST-SSR marker based, molecular identification of 8 elite cultivars and 88 accessions in turmeric. Fifty EST-SSR primers were screened against eight cultivars of turmeric (Suroma, Roma, Lakadong, Megha, Alleppey Supreme, Kedaram, Pratibha, and Suvarna); out of which 11 primers showed polymorphic banding pattern. The polymorphic information content (PIC) of these primers ranged from 0.13 to 0.48. However, only three SSR loci (CSSR 14, CSSR 15, and CSSR 18) gave reproducible unique banding pattern clearly distinguishing the cultivars 'Lakadong' and 'Suvarna' from other cultivars tested. These three unique SSR markers also proved to be effective in identification of 'Lakadong' cultivars when analysed with 88 accessions of turmeric collected from different agro-climatic regions. Furthermore, two identified cultivars (Lakadong and Suvarna) could also be precisely differentiated when analysed and based on phylogenetic tree, with other 94 genotypes of turmeric. The novel SSR markers can be used for identification and authentication of two commercially important turmeric cultivars 'Lakadong' and 'Suvarna'.

    Extracts prepared from turmeric (Curcuma longa L., [Zingiberaceae]) containing bioactive phenolic curcuminoids were evaluated for bone-protective effects in a hypogonadal rat model of postmenopausal osteoporosis. Three-month female Sprague-Dawley rats were ovariectomized (OVX) and treated with a chemically complex turmeric fraction (41% curcuminoids by weight) or a curcuminoid-enriched turmeric fraction (94% curcuminoids by weight), both dosed at 60 mg/kg 3x per week, or vehicle alone. Effects of two months of treatment on OVX-induced bone loss were followed prospectively by serial assessment of bone mineral density (BMD) of the distal femur using dual-energy X-ray absorptiometry (DXA), while treatment effects on trabecular bone microarchitecture were assessed at two months by microcomputerized tomography (microCT). Chemically complex turmeric did not prevent bone loss, however, the curcuminoid-enriched turmeric prevented up to 50% of OVX-induced loss of trabecular bone and also preserved the number and connectedness of the strut-like trabeculae. These results suggest that turmeric may have bone-protective effects but that extract composition is a critical factor.

    Previous animal studies have shown that Curcuma (C.) longa lowers plasma glucose. C. longa may thus be a promising ingredient in functional foods aimed at preventing type 2 diabetes. The purpose of the study is to study the effect of C. longa on postprandial plasma glucose, insulin levels and glycemic index (GI) in healthy subjects. Fourteen healthy subjects were assessed in a crossover trial. A standard 75 g oral glucose tolerance test (OGTT) was administered together with capsules containing a placebo or C. longa. Finger-prick capillary and venous blood samples were collected before, and 15, 30, 45, 60, 90, and 120 min after the start of the OGTT to measure the glucose and insulin levels, respectively. The ingestion of 6 g C. longa had no significant effect on the glucose response. The change in insulin was significantly higher 30 min (P = 0.03) and 60 min (P = 0.041) after the OGTT including C. longa. The insulin AUCs were also significantly higher after the ingestion of C. longa, 15 (P = 0.048), 30 (P = 0.035), 90 (P = 0.03), and 120 (P = 0.02) minutes after the OGTT. The ingestion of 6 g C. longa increased postprandial serum insulin levels, but did not seem to affect plasma glucose levels or GI, in healthy subjects. The results indicate that C. longa may have an effect on insulin secretion.

    Oxidative stress is known to contribute to the pathogenesis of neurodegenerative disorders. An ethanolic turmeric (Curcuma longa L.) extract containing curcumin has been reported to produce antioxidant effects. The present study aims to investigate the possible neuroprotective effects of the ethanolic turmeric extract against trimethyltin (TMT)-induced oxidative stress in Sprague Dawley rats. The ethanolic turmeric extract and citicoline were administered to the TMT exposed rats from day 1 to day 28 of the experiment. The TMT injection was administered on day 8 of the experiment. The plasma and brain malondialdehyde (MDA) and reduced glutathione (GSH) levels, and the activities of the superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) enzymes in the brain were examined at the end of the experiment. The administration of 200 mg/kg bw of the ethanolic turmeric extract prevented oxidative stress by decreasing the plasma and brain MDA levels and increasing the SOD, CAT, and GPx enzyme activities and GSH levels in the brain. These effects seem to be comparable to those of citicoline. The ethanolic turmeric extract at a dose of 200 mg/kg bw may exert neuroprotective effects on TMT-exposed Sprague Dawley rats by preventing them from oxidative stress.

    The antifungal activity and potential mechanisms in vitro as well as anti-aflatoxigenic efficiency in vivo of natural essential oil (EO) derived from turmeric (Curcuma longa L.) against Aspergillus flavus was intensively investigated. Based on the previous chemical characterization of turmeric EO by gas chromatography-mass spectrometry, the substantially antifungal activities of turmeric EO on the mycelial growth, spore germination and aflatoxin production were observed in a dose-dependent manner. Furthermore, these antifungal effects were related to the disruption of fungal cell endomembrane system including the plasma membrane and mitochondria, specifically i.e. the inhibition of ergosterol synthesis, mitochondrial ATPase, malate dehydrogenase, and succinate dehydrogenase activities. Moreover, the down-regulation profiles of turmeric EO on the relative expression of mycotoxin genes in aflatoxin biosynthetic pathway revealed its anti-aflatoxigenic mechanism. Finally, the suppression effect of fungal contamination in maize indicated that turmeric EO has potential as an eco-friendly antifungal agent. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Turmeric (Curcuma longa L. [Zingiberaceae]) is used in the treatment of a variety of conditions including pesticide-induced toxicity. The study reports the antioxidant properties and the protective effects of turmeric against carbofuran (CF)-induced toxicity in rats. The antioxidant potential was determined by using free radicals scavenging activity and ferric reducing antioxidant power values. Male Wistar rats were randomly divided into four groups, designated as control, turmeric (100 mg/kg/day), CF (1 mg/kg/day) and turmeric (100 mg/kg/day) + CF (1 mg/kg/day) treatments. All of the doses were administered orally for 28 consecutive days. The biological activity of the turmeric and CF was determined by using several standard biochemical methods. Turmeric contains high concentrations of polyphenols (8.97 ± 0.15 g GAEs), flavonoids (5.46 ± 0.29 g CEs), ascorbic acid (0.06 ± 0.00 mg AEs) and FRAP value (1972.66 ± 104.78 μM Fe 2+ ) per 100 g of sample. Oral administration of CF caused significant changes in some of the blood indices, such as, mean corpuscular volume, corpuscular hemoglobin, white blood cell, platelet distribution width and induced severe hepatic injuries associated with oxidative stress, as observed by the significantly higher lipid peroxidation (LPO) levels when compared to control, while the activities of cellular antioxidant enzymes (including superoxide dismutase and glutathione peroxidase) were significantly suppressed in the liver tissue. Turmeric supplementation could protect against CF-induced hematological perturbations and hepatic injuries in rats, plausibly by the up-regulation of antioxidant enzymes and inhibition of LPO to confer the protective effect.

    Turmeric is well known for a wide range of medicinal properties. Essential oil of turmeric leaves (Curcuma longa L.) were evaluated at varying concentrations of 0.01, 0.05, 0.1, 0.5, 0.75, 1.0 and 1.5% (v/v) in Yeast Extract Sucrose (YES) broth inoculated with spore suspension of Aspergillus flavus of 10(6)conidia/ml. These were evaluated for their potential in the control of aflatoxigenic fungus A. flavus and aflatoxin production. Turmeric leaf oil exhibited 95.3% and 100% inhibition of toxin production respectively at 1.0% and 1.5%. The extent of inhibition of fungal growth and aflatoxin production was dependent on the concentration of essential oil used. The oil exhibited significant inhibition of fungal growth as well as aflatoxins B(1) and G(1) production. The LD(50) and LD(90) were also determined. GC-MS analysis of the oil showed α-phellandrene, p-cymene and terpinolene as the major components in turmeric leaf oil. The possibility of using these phytochemical components as bio-preservatives for storage of spices is discussed. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Curcuma longa (turmeric) is commonly used as spice and also used to treat fever, cough and febrile convulsions in Nigeria. This study determined the chemical composition of the essential oil of C. longa and evaluated its neuropharmacological activity in mice. Essential oil of C. longa (EOCL) fresh rhizome was obtained by hydrodistillation and its chemical composition determined by GC-MS. Acute toxicity (LD 50 ) profile of the essential oil was determined orally (p.o.) and intraperitoneally (i.p.); and the EOCL (50-200 mg/kg, i.p.) was evaluated for its behavioural, anxiolytic, sedative and anticonvulsant activities using appropriate models in Albino mice (Vom Strain, Jos, Nigeria). Analysis of the oil showed the presence of 23 compounds with turmerone (35.9%) being the major component. The LD 50 values obtained for the mice were 2154 mg/kg, p.o., and 693 mg/kg, i.p. The EOCL (50-200 mg/kg, i.p.) caused significant (p longa species was turmerone; the oil was slightly toxic orally but moderately toxic intraperitoneally in mice; exhibited significant anxiolytic, sedative and anticonvulsant activities in mice.

    Full Text Available Renal ischemia/reperfusion (I/R injury is a major cause of acute renal failure (ARF, which is faced in many clinical situations. This study was designed to investigate the effect of pre-treatment with turmeric (Curcuma longa linn powder on kidney histopathology and function markers in renal ischemia / reperfusion (IR induced injury in the rats. A total of 80 male Wistar rats were randomly divided into 4 groups: sham, IR model and two I/R+TREE (2%and4% - treated groups (n=20 per group. I/R groups’ kidneys were subjected to 60 min of global ischemia at 37oc followed by 30min of reperfusion. After 24h of reperfusion period, the rats were sacrificed. Kidney function tests and histopathological examination were also performed. Results were compared with a group of rats with sham operation. High serum creatinine, blood urea nitrogen and uric acid were observed in I/R rats compared to the sham rats. Pre-treatment of turmeric powder for 30 days prior to IR operation improved renal function reduced IR induced renal inflammatory and oxidative injury. The results of this study showed that turmeric powder significantly prevented renal I/R-induced functional and histological injuries.

    The drug yielding potential of turmeric ( Curcuma longa L.) is largely due to the presence of phyto-constituent 'curcumin.' Curcumin has been found to possess a myriad of therapeutic activities ranging from anti-inflammatory to neuroprotective. Lack of requisite high curcumin containing genotypes and variation in the curcumin content of turmeric at different agro climatic regions are the major stumbling blocks in commercial production of turmeric. Curcumin content of turmeric is greatly influenced by environmental factors. Hence, a prediction model based on artificial neural network (ANN) was developed to map genome environment interaction basing on curcumin content, soli and climatic factors from different agroclimatic regions for prediction of maximum curcumin content at various sites to facilitate the selection of suitable region for commercial cultivation of turmeric. The ANN model was developed and tested using a data set of 119 generated by collecting samples from 8 different agroclimatic regions of Odisha. The curcumin content from these samples was measured that varied from 7.2% to 0.4%. The ANN model was trained with 11 parameters of soil and climatic factors as input and curcumin content as output. The results showed that feed-forward ANN model with 8 nodes (MLFN-8) was the most suitable one with R 2 value of 0.91. Sensitivity analysis revealed that minimum relative humidity, altitude, soil nitrogen content and soil pH had greater effect on curcumin content. This ANN model has shown proven efficiency for predicting and optimizing the curcumin content at a specific site.

    Endophytic fungi have been isolated from the healthy turmeric (Curcuma longa L.) rhizomes from South India. Thirty-one endophytes were identified based on morphological and ITS-rDNA sequence analysis. The isolated endophytes were screened for antagonistic activity against Pythium aphanidermatum (Edson) Fitzp., and Rhizoctonia solani Kuhn., causing rhizome rot and leaf blight diseases in turmeric respectively. Results revealed that only six endophytes showed > 70% suppression of test pathogens in antagonistic dual culture assays. The endophyte T. harzianum TharDOB-31 showed significant in vitro mycelial growth inhibition of P. aphanidermatum (76.0%) and R. solani (76.9%) when tested by dual culture method. The SEM studies of interaction zone showed morphological abnormalities like parasitism, shriveling, breakage and lysis of hyphae of the pathogens by endophyte TharDOB-31. Selected endophytic isolates recorded multiple plant growth promoting traits in in vitro studies. The rhizome bacterization followed by soil application of endophyte TharDOB-31 showed lowest Percent Disease Incidence of rhizome rot and leaf blight, 13.8 and 11.6% respectively. The treatment of TharDOB-31 exhibited significant increase in plant height (85 cm) and fresh rhizome yield/plant (425 g) in comparison with untreated control under greenhouse condition. The confocal microscopy validates the colonization of the TharDOB-31 in turmeric rhizomes. The secondary metabolites in ethyl acetate extract of TharDOB-31 were found to contain higher number of antifungal compounds by high resolution liquid chromatograph mass spectrometer analysis. Thereby, endophyte T. harzianum isolate can be exploited as a potential biocontrol agent for suppressing rhizome rot and leaf blight diseases in turmeric.

    The species of Zingiberaceae family are characterized for rhizome. Phenolic constituents like curcuminoids and gingerols have had reports of biological activities. Food irradiation is an effective means of preservation, however it is important to ensure that their functional properties are not compromised. The aim of this study was to evaluate the effectiveness of gamma radiation from 60 Co in doses of 0, 5, 10, 15 and 20 kGy on species of Zingiberaceae: turmeric (Curcuma longa L.), ginger (Zingiber officinale Roscoe) and zedoaria (Curcuma zedoaria (Christm.) Roscoe). The qualitative determination of bioactive compounds profile was performed by thin layer chromatography. The quantification of phenolic compounds was performed by Folin-Ciocalteu method and assessing the potential of antioxidant activity by the free radical [2,2 difenil-1-pricril-hydrazyl (DPPH.] scavenging and by Rancimat method. The curcumin and 6-gingerol quantification was performed by High Performance Liquid Chromatography. Compared to control, there were significant losses of total phenolic compounds in turmeric samples irradiated with 15kGy and 20kGy. There were significant decreases in the ability to scavenge DPPH in irradiated ginger extracts and zedoaria extract irradiated with 20kGy. The Antioxidant Activity Index was significantly lower in 5kGy and 15kGy irradiated turmeric extracts and in irradiated zedoaria extracts. The curcumin quantification was significantly lower in 15kGy irradiated turmeric extracts and there was no significant difference in the 6-gingerol quantification between ginger extracts. It is concluded that gamma radiation processing technology in Zingiberaceae can be viable for industry. To maintain safety of antioxidant activity it should be applied doses up 10kGy. (author)

    Full Text Available Increasing restrictions on the use of artificial pigments in the food industry, imposed by the international market, have increased the importance of raw materials containing natural pigments. Of those natural substances with potential applications turmeric rhizomes (Curcuma longa L, are one of the most important natural sources of yellow coloring. Three different pigments (curcumin, desmetoxycurcumin, and bis-desmetoxycurcumin constitute the curcuminoids. These pigments are largely used in the food industry as substitutes for synthetic dyes like tartrazin. Extraction of curcuminoids from tumeric rhizomes with supercritical CO2 can be applied as an alternative method to obtain curcuminoids, as natural pigments are in general unstable, and hence degrade when submitted to extraction with organic solvents at high temperatures. Extraction experiments were carried out in a supercritical extraction pilot plant at pressures between 25 and 30 MPa and a temperature of 318 K. The influence of drying pretreatment on extraction yield was evaluated by analyzing the mass transfer kinetics and the content of curcuminoids in the extracts during the course of extraction. The chemical identification of curcuminoids in both the extract and the residual solid was performed by spectrophotometry. Mass transfer within the solid matrix was described by a linear first-order desorption model, while that in the gas phase was described by a convective mass transfer model. Experimental results showed that the concentration profile for curcuminoids during the supercritical extraction process was higher when the turmeric rhizomes were submitted to a drying pretreatment at 343 K.

    Ginger (Zingiber officinale Rosc.) and turmeric (Curcuma longa L.), members of the Zingiberaceae, are widely used in traditional Asian cuisines and herbal medicine. Gingerols and diarylheptanoids, important compounds from these plants, appear to be produced by enzymes of the type III polyketide synthase class. Previous efforts to detect activity of such enzymes in tissues from these plants were only marginally successful in turmeric and completely unsuccessful in ginger because of very rapid hydrolysis of the hydroxycinnamoyl-CoA substrates (p-coumaroyl-CoA, feruloyl-CoA and caffeoyl-CoA) in these assays, presumably due to the presence of thioesterases in these tissues. In order to determine whether such thioesterase activities were specific and could be reduced so that the polyketide synthase activities could be better characterized, three inhibitors of the thioesterase domain of fatty acid synthase were tested in assays with leaf and rhizome crude protein extracts from these plants: orlistat, a reduced form of lipstatin, and peptide 1 and peptide 2 from hydrolysates of soybean β-conglycinin. Results of these analyses indicated that specific thioesterases do exist in these plants and that they could indeed be inhibited, with highest inhibition occurring with a mixture of these three compounds, leading for example to a reduction of caffeoyl-CoA hydrolysis in leaves and rhizomes of ginger by 40-fold and 27-fold, respectively.

    Curcuminoids from rhizomes of Curcuma longa possess various biological activities. However, low aqueous solubility and consequent poor bioavailability of curcuminoids are major limitations to their use. In this study, curcuminoids extracted from turmeric powder using stevioside (Ste), rebaudioside A (RebA), or steviol glucosides (SG) were solubilized in water. The optimum extraction condition by Ste, RebA, or SG resulted in 11.3, 9.7, or 6.7mg/ml water soluble curcuminoids. Curcuminoids solubilized in water showed 80% stability at pH from 6.0 to 10.0 after 1week of storage at 25°C. The particle sizes of curcuminoids prepared with Ste, RebA, and SG were 110.8, 95.7, and 32.7nm, respectively. The water soluble turmeric extracts prepared with Ste, RebA, and SG showed the 2,2-diphenyl-1-picrylhydrazyl radical scavenging (SC50) activities of 127.6, 105.4, and 109.8μg/ml, and the inhibition activities (IC50) against NS2B-NS3(pro) from dengue virus type IV of 14.1, 24.0 and 15.3μg/ml, respectively.

    Considering that as many as 80% of the anticancer drugs have their roots in natural products derived from traditional medicine, we examined compounds other than curcumin from turmeric (Curcuma longa) that could exhibit anticancer potential. Present study describes the isolation and characterization of another turmeric-derived compound, β-sesquiphellandrene (SQP) that exhibits anticancer potential comparable to that of curcumin. We isolated several compounds from turmeric, including SQP, α-curcumene, ar-turmerone, α-turmerone, β-turmerone, and γ-turmerone, only SQP was found to have antiproliferative effects comparable to those of curcumin in human leukemia, multiple myeloma, and colorectal cancer cells. While lack of the NF-κB-p65 protein had no effect on the activity of SQP, lung cancer cells that expressed p53 were more susceptible to the cytotoxic effect of SQP than were cells that lacked p53 expression. SQP was also found to be highly effective in suppressing cancer cell colony formation and inducing apoptosis, as shown by assays of intracellular esterase activity, plasma membrane integrity, and cell-cycle phase. SQP was found to induce cytochrome c release and activate caspases that lead to poly ADP ribose polymerase cleavage. SQP exposure was associated with downregulation of cell survival proteins such cFLIP, Bcl-xL, Bcl-2, c-IAP1, and survivin. Furthermore, SQP was found to be synergistic with the chemotherapeutic agents velcade, thalidomide and capecitabine. Overall, our results indicate that SQP has anticancer potential comparable to that of curcumin.

    Phytocystatin, a type of protease inhibitor (PI), plays major roles in plant defense mechanisms and has been reported to show antipathogenic properties and plant stress tolerance. Recombinant plant PIs are gaining popularity as potential candidates in engineering of crop protection and in synthesizing medicine. It is therefore crucial to identify PI from novel sources like Curcuma longa as it is more effective in combating against pathogens due to its novelty. In this study, a novel cDNA fragment encoding phytocystatin was isolated using degenerate PCR primers, designed from consensus regions of phytocystatin from other plant species. A full-length cDNA of the phytocystatin gene, designated CypCl, was acquired using 5'/3' rapid amplification of cDNA ends method and it has been deposited in NCBI database (accession number KF545954.1). It has a 687 bp long open reading frame (ORF) which encodes 228 amino acids. BLAST result indicated that CypCl is similar to cystatin protease inhibitor from Cucumis sativus with 74% max identity. Sequence analysis showed that CypCl contains most of the motifs found in a cystatin, including a G residue, LARFAV-, QxVxG sequence, PW dipeptide, and SNSL sequence at C-terminal extension. Phylogenetic studies also showed that CypCl is related to phytocystatin from Elaeis guineensis.

It is therefore crucial to identify PI from novel sources like Curcuma longa as it is more effective in combating against pathogens due to its novelty. In this study, a novel cDNA fragment encoding phytocystatin was isolated using degenerate PCR primers, designed from consensus regions of phytocystatin from other plant species. A full-length cDNA of the phytocystatin gene, designated CypCl, was acquired using 5′/3′ rapid amplification of cDNA ends method and it has been deposited in NCBI database (accession number KF545954.1). It has a 687 bp long open reading frame (ORF) which encodes 228 amino acids. BLAST result indicated that CypCl is similar to cystatin protease inhibitor from Cucumis sativus with 74% max identity. Sequence analysis showed that CypCl contains most of the motifs found in a cystatin, including a G residue, LARFAV-, QxVxG sequence, PW dipeptide, and SNSL sequence at C-terminal extension. Phylogenetic studies also showed that CypCl is related to phytocystatin from Elaeis guineensis. PMID:25853138

    Turmeric (Curcuma longa) has traditionally been used to treat pain, fever, allergic and inflammatory diseases such as bronchitis, arthritis, and dermatitis. In particular, turmeric and its active component, curcumin, were effective in ameliorating immune disorders including allergies. However, the effects of turmeric and curcumin have not yet been tested on food allergies. Mice were immunized with intraperitoneal ovalbumin (OVA) and alum. The mice were orally challenged with 50mg OVA, and treated with turmeric extract (100mg/kg), curcumin (3mg/kg or 30 mg/kg) for 16 days. Food allergy symptoms including decreased rectal temperature, diarrhea, and anaphylaxis were evaluated. In addition, cytokines, immunoglobulins, and mouse mast cell protease-1 (mMCP-1) were evaluated using ELISA. Turmeric significantly attenuated food allergy symptoms (decreased rectal temperature and anaphylactic response) induced by OVA, but curcumin showed weak improvement. Turmeric also inhibited IgE, IgG1, and mMCP-1 levels increased by OVA. Turmeric reduced type 2 helper cell (Th2)-related cytokines and enhanced a Th1-related cytokine. Turmeric ameliorated OVA-induced food allergy by maintaining Th1/Th2 balance. Furthermore, turmeric was confirmed anti-allergic effect through promoting Th1 responses on Th2-dominant immune responses in immunized mice. Turmeric significantly ameliorated food allergic symptoms in a mouse model of food allergy. The turmeric as an anti-allergic agent showed immune regulatory effects through maintaining Th1/Th2 immune balance, whereas curcumin appeared immune suppressive effects. Therefore, we suggest that administration of turmeric including various components may be useful to ameliorate Th2-mediated allergic disorders such as food allergy, atopic dermatitis, and asthma.

    The present study investigated the acute, subchronic and genotoxicity of turmeric essential oil (TEO) from Curcuma longa L. Acute administration of TEO was done as single dose up to 5 g of TEO per kg body weight and subchronic toxicity study for thirteen weeks was done by daily oral administration of TEO at doses 0.1, 0.25 and 0.5 g/kg b.wt. in Wistar rats. There were no mortality, adverse clinical signs or changes in body weight; water and food consumption during acute as well as subchronic toxicity studies. Indicators of hepatic function such as aspartate aminotransferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP) were unchanged in treated animals compared to untreated animals. Oral administration of TEO for 13 weeks did not alter total cholesterol, triglycerides, markers of renal function, serum electrolyte parameters and histopathology of tissues. TEO did not produce any mutagenicity to Salmonella typhimurium TA-98, TA-100, TA-102 and TA-1535 with or without metabolic activation. Administration of TEO to rats (1 g/kg b.wt.) for 14 days did not produce any chromosome aberration or micronuclei in rat bone marrow cells and did not produce any DNA damage as seen by comet assay confirming the non toxicity of TEO.

    Potency of medicinal plant is related to microorganisms lived in the plant tissue. Those microorganisms are known as endophytic microbes that live and form colonies in the plant tissue without harming its host. Each plant may contains several endophytic microbes that produce biological compounds or secondary metabolites due to co-evolution or genetic transfer from the host plant to endophytic microbes. Endophytic fungi research done for turmeric plant (Curcuma longa L.) gave 44 isolated fungi as results. Those 44 fungi isolated were fermented in Potato Dextrose Broth (PDB) media, filtered, extracted with ethylacetate and then were analyzed by Thin Layer Chromatography (TLC) method and tested for their antioxidant activity by radical scavenging method. The antioxidant activity of the ethylacetate filtrate extracts either from Sukabumi or Cibinong were higher than the biomass extracts. There were 6 fungi that showed antioxidant activities over 65%, i.e., with code name K.Cl.Sb.R9 (93.58%), K.Cl.Sb.A11 (81.49%), KCl.Sb.B1 (78.81%), KCl.Sb.R11 (71.67%) and K.Cl.Sb.A12 (67.76%) from Sukabumi and K.Cl.Cb.U1 (69.27%) from Cibinong. These results showed that bioproduction by endophytic microbes can gave potential antioxidant compounds.

    This observational study was conducted during the period from July 2010 to June 2011 in the Department of Pharmacology in the collaboration of Department of Microbiology, Mymensingh Medical College, Mymensingh to determine the profile of antibacterial effect of Crude Turmeric paste aqueous turmeric extract, and standard antibiotic Amikacin against Staphylococcus aureus and Escherichia coli. Three separate experiments were done e.g. (Expt- I) Inhibitory effect of Crude Turmeric paste incorporated into nutrient agar (NA) media, (Expt- II) Minimum inhibitory concentration of (a) Aqueous Turmeric extract and (b) Amikacin by broth dilution technique and (Expt-III) their subculture study in nutrient agar (NA) media for confirmation of respective results of previous experiments. Inhibitory effects were observed against the growth of Staph Aureus and Esch coli at 10% and 30% respectively of Crude Turmeric paste incorporated into NA media. The broth dilution technique was followed to determine the MIC of Aqueous Turmeric extract and Amikacin. The MIC of Aqueous Turmeric extract was 800 μg/ml against Staph aureus and that against Esch coli was 2000 μg/ml and the MIC of Amikacin was 10 μg/ml for both the bacteria. The MIC of Amikacin was the lowest in comparison to MIC of Aqueous Turmeric extract for complete inhibition of growth of Staph aureus and Esch coli. The subculture study showed similar results with that of previous experiments in terms of inhibitory effects of Crude Turmeric paste and MIC of Aqueous Turmeric extract and Amikacin against all of the organisms studied.

    The objective of this study was to evaluate the effect of Curcuma longa powder and ascorbic acid on some quality traits of rabbit burgers. The burgers (burgers control with no additives; burgers with 3.5 g of turmeric powder/100g meat; burgers with 0.1g of ascorbic acid/100g meat) were analyzed at Days 0 and 7 for pH, color, drip loss, cooking loss, fatty acid profile, TBARS, antioxidant capacity (ABTS, DPPH and FRAP) and microbial growth. The addition of turmeric powder modified the meat color, produced an antioxidant capacity similar to ascorbic acid and determined a lower cooking loss than other formulations. Turmeric powder might be considered as a useful natural antioxidant, increasing the quality and extending the shelf life of rabbit burgers. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Curcuma longa (turmeric) has been used widely as a spice, particularly in Asian countries. It is also used in the Ayurvedic system of medicine as an antiinflammatory and antimicrobial agent and for numerous other curative properties. The aim of this study was to investigate the effects of an aqueous extract of Curcuma longa (AEC) on tissues involved in glucose homeostasis. The extract was prepared by soaking 100 g of ground turmeric in 1 L of water, which was filtered and stored at -20°C prior to use. Pancreas and muscle tissues of adult mice were cultured in DMEM with 5 or 12 mmol/L glucose and varying doses of extract. The AEC stimulated insulin secretion from mouse pancreatic tissues under both basal and hyperglycaemic conditions, although the maximum effect was only 68% of that of tolbutamide. The AEC induced stepwise stimulation of glucose uptake from abdominal muscle tissues in the presence and absence of insulin, and the combination of AEC and insulin significantly potentiated the glucose uptake into abdominal muscle tissue. However, this effect was attenuated by wortmannin, suggesting that AEC possibly acts via the insulin-mediated glucose uptake pathway. In summary, water soluble compounds of turmeric exhibit insulin releasing and mimicking actions within in vitro tissue culture conditions. Copyright © 2010 John Wiley & Sons, Ltd.

    Curcumin is a hydrophobic polyphenolic compound derived from turmeric rhizome, which consists about 2-5% of the total rhizome content and is a more valuable component of turmeric. For reducing the drawbacks of conventional extraction (using organic solvents) of curcumin, the water as a clean solvent was used for extracting curcumin. Subcritical water extraction (SWE) experimental setup was fabricated in a laboratory scale and the influences of some parameters (e.g. extraction temperature, particle size, retention time and pressure) on the yield of extraction were investigated. Optimum extraction conditions such as SWE pressure of 10bar, extractive temperature of 140°C, particle size of 0.71mm and retention time of 14min were defined. The maximum amount of curcumin extracted at the optimum condition was 3.8wt%. The yield of curcumin extraction was more than 76wt% with regards to the maximum possible curcumin content of turmeric, as known to be 5%. The scanning electron microscope (SEM) images from the outer surface of turmeric, before and after extraction, clearly demonstrated the effect of each parameter; changes in porosity and hardness of turmeric that is directly related to the amount of extracted curcumin in process optimization of the extraction parameters.

    The antibiofilm and antioxidant activities associated with turmeric were the main focus of the study. Antibacterial activity was explored against bacteria isolated from dental plaques and dental unit water lines exhibiting resistance against antibiotics and biocides respectively. This study provides a comparison of the natural plant extract against synthetic mouthwash, chemicals and commonly prescribed antibiotics. Methanol extract was more effective as compared to other extracts. Minimum inhibitory concentrations (MIC) ranged from 2.5-10mg/ml. Time based killing kinetic assay showed a significant reduction of bacterial load with increasing concentration of turmeric. Micro titer plate assay indicated significant inhibition of biofilm formation in cells treated with turmeric extract. Phytochemical screening of plant extracts showed the presence of vital secondary metabolites. Flavonoid content and total phenolic content varied among extracts, phenolic content for methanolic extract was 61.669 mg GAE/ gm dry extract and flavonoid content was 3.119mg quercitin/gm dry extract. The values of ferric reducing power were in the range of 5.55- 15.55 mmol of FeSO4 equivalent/ liter of the extract. Antioxidant activities and total phenolic content of the turmeric extracts had significant positive correlation. On the basis of these results turmeric may confidently be recommended as natural antibiofilm and antioxidant agent.

    Turmeric has been extensively utilized in Indian and Chinese medicine for its immune-modulatory properties. Dendritic cells (DCs) are antigen-presenting cells specialized to initiate and regulate immunity. The ability of DCs to initiate immunity is linked to their activation status. The effects of turmeric on human DCs have not been studied. Here we show that hydroethanolic (HEE) but not lipophilic "supercritical" extraction (SCE) of turmeric inhibits the activation of human DCs in response to inflammatory cytokines. Treatment of DCs with HEE also inhibits the ability of DCs to stimulate the mixed lymphocyte reaction (MLR). Importantly, the lipophilic fraction does not synergize with the hydroethanolic fraction for the ability of inhibiting DC maturation. Rather, culturing of DCs with the combination of HEE and SCE leads to partial abrogation of the effects of HEE on the MLR initiated by DCs. These data provide a mechanism for the anti-inflammatory properties of turmeric. However, they suggest that these extracts are not synergistic and may contain components with mutually antagonistic effects on human DCs. Harnessing the immune effects of turmeric may benefit from specifically targeting the active fractions.

    Turmeric (the rhizomes of Curcuma longa L., Zingiberacease) is widely used as a dietary pigment and spice, and has been traditionally used for the treatment of inflammation, skin wounds and hepatic disorders in Ayurvedic, Unani and Chinese medicine. Although the topical application or oral administration of turmeric is used to improve skin trouble, there is no evidence to support this effect. The aim of this study was to clarify whether turmeric prevents chronic ultraviolet B (UVB)-irradiated skin damage. We examined the effects of a turmeric extract on skin damage including changes in skin thickness and elasticity, pigmentation and wrinkling caused by long-term, low-dose ultraviolet B irradiation in melanin-possessing hairless mice. The extract (at 300 or 1000 mg/kg, twice daily) prevented an increase in skin thickness and a reduction in skin elasticity induced by chronic UVB exposure. It also prevented the formation of wrinkles and melanin (at 1000 mg/kg, twice daily) as well as increases in the diameter and length of skin blood vessels and in the expression of matrix metalloproteinase-2 (MMP-2). Prevention of UVB-induced skin aging by turmeric may be due to the inhibition of increases in MMP-2 expression caused by chronic irradiation.

    Turmeric, the rhizome of Curcuma longa L., has a wide range of effects on human health. The chemistry includes curcuminoids and sesquiterpenoids as components, which are known to have antioxidative, anticarcinogenic, and antiinflammatory activities. In this study, we investigated the effects of three turmeric extracts on blood glucose levels in type 2 diabetic KK-A(y) mice (6 weeks old, n = 5/group). These turmeric extracts were obtained by ethanol extraction (E-ext) to yield both curcuminoids and sesquiterpenoids, hexane extraction (H-ext) to yield sesquiterpenoids, and ethanol extraction from hexane-extraction residue (HE-ext) to yield curcuminoids. The control group was fed a basal diet, while the other groups were fed a diet containing 0.1 or 0.5 g of H-ext or HE-ext/100 g of diet or 0.2 or 1.0 g of E-ext/100 g of diet for 4 weeks. Although blood glucose levels in the control group significantly increased (P turmeric extracts had human peroxisome proliferator-activated receptor-gamma (PPAR-gamma) ligand-binding activity in a GAL4-PPAR-gamma chimera assay. Also, curcumin, demethoxycurcumin, bisdemethoxycurcumin, and ar-turmerone had PPAR-gamma ligand-binding activity. These results indicate that both curcuminoids and sesquiterpenoids in turmeric exhibit hypoglycemic effects via PPAR-gamma activation as one of the mechanisms, and suggest that E-ext including curcuminoids and sesquiterpenoids has the additive or synergistic effects of both components.

    In this report, we present the research results on using the conventional method and microwave technology to extract curcuminoid from turmeric roots originated in different regions of Northern Vietnam. This method is simple, yet economical, non-toxic and still able to achieve high extraction performance to get curcuminoid from turmeric roots. The detailed results on the Raman vibration spectra combined with X-ray powder diffraction and high-performance liquid chromatography/mass spectrometry allowed the evaluation of each batch of curcumin crystalline powder sample received, under the conditions of applied fabrication technology. Also, the absorption and fluorescence spectroscopies of the samples are presented in the paper. The information to be presented in this paper: absorption and fluorescence spectroscopies of the samples; new experimental study results on applied technology to mass-produce curcumin from turmeric rhizomes; comparative study results between fabricated samples and marketing curcumin products-to state the complexity of co-existing crystalline phase in curcumin powder samples. We noticed that, it is possible to use the vibration line at ~959 cm(-1)-characteristic of the ν C=O vibration, and the ~1625 cm(-1) line-characteristic of the ν C=O and ν C=C vibration in curcumin molecules, for preliminary quality assessment of naturally originated curcumin crystalline powder samples. Data on these new optical spectra will contribute to the bringing of detailed information on natural curcumin in Vietnam, serving research purposes and applications of natural curcumin powder and nanocurcumin in Vietnam, as well as being initial materials for the pharmaceutical, cosmetics or functional food industries.

    Turmeric ( Curcuma longa ) is a widely used spice that has various biological effects, and aqueous extracts of turmeric exhibit potent antioxidant activity and anti-inflammatory activity. Bisacurone, a component of turmeric extract, is known to have similar effects. Oxidative stress and inflammatory cytokines play an important role in ethanol-induced liver injury. This study was performed to evaluate the influence of a hot water extract of C. longa (WEC) or bisacurone on acute ethanol-induced liver injury. C57BL/6 mice were orally administered WEC (20 mg/kg body weight; BW) or bisacurone (60 µg/kg BW) at 30 min before a single dose of ethanol was given by oral administration (3·0 g/kg BW). Plasma levels of aspartate aminotransferase and alanine aminotransferase were markedly increased in ethanol-treated mice, while the increase of these enzymes was significantly suppressed by prior administration of WEC. The increase of alanine aminotransferase was also significantly suppressed by pretreatment with bisacurone. Compared with control mice, animals given WEC had higher hepatic tissue levels of superoxide dismutase and glutathione, as well as lower hepatic tissue levels of thiobarbituric acid-reactive substances, TNF-α protein and IL-6 mRNA. These results suggest that oral administration of WEC may have a protective effect against ethanol-induced liver injury by suppressing hepatic oxidation and inflammation, at least partly through the effects of bisacurone.

    A wide range of proteinaceous inhibitors are present in plants to protect themselves from hydrolytic enzymes. In this study, turmerin, a water-soluble peptide in turmeric rhizomes, was evaluated for its inhibitory potential against glucosidase and its antioxidant (AO) capacity. Turmerin inhibited α-amylase and α-glucosidase activities with IC₅₀ values 31 and 192 µg mL⁻¹, respectively. Under the experimental conditions, those values for a standard glucosidase inhibitor, acarbose, were 81 and 296 µg mL⁻¹, respectively. The AO capacity of turmerin was evaluated using in vitro assay systems. Turmerin showed good DPPH (IC₅₀ = 29 µg mL⁻¹) and superoxide (IC₅₀ = 48 µg mL⁻¹) and moderate ABTS (IC₅₀ = 83 µg mL⁻¹) radical scavenging and Fe(II) chelation (IC₅₀ = 101 µg mL⁻¹) capacities. The inhibitory potential showed by turmerin against enzymes linked to type 2 diabetes, as well as its moderate AO capacity, could rationalise the traditional usage of turmeric rhizome preparations against diabetes.

    Full Text Available Drying of turmeric was carried out in a solar conduction dryer (SCD. Drying air temperature was achieved around 39–51 °C for an ambient temperature in the range of 25–28 °C. Moisture content from 78.65% (wb, was reduced to 6.36% (wb and 5.50% (wb for solid and sliced samples respectively in 12 h effective drying time. Drying curve of sliced samples showed more uniform falling in comparison to that of whole samples. The average effective moisture diffusivity was found to be 1.852 × 10−10 m2 s−1 for slab samples and 1.456 × 10−10 m2 s−1 for solid samples. Out of four models tried for simulation, Page model was found as best fitted thin layer drying model when simulation was done for all the drying data. The overall thermal efficiency of the dryer was found to be 55%. Drying of sliced rhizomes showed better drying kinetics and effective drying time could be reduced by slicing instead of drying in whole form.

    Native, intact (TrPP) and modified, low-molecular-weight (MTrPP) forms of pectic polysaccharides isolated from turmeric were evaluated for ulcer-preventive potentials in in vitro and in vivo models. Data indicated that MTrPP possessed significantly better ulcer-preventive property than TrPP; inhibiting ulcer scores up to 85%. Results were substantiated by effective muco-protection, H(+),K(+)-ATPase down-regulation, inhibition of H. pylori growth/adherence, higher antioxidant/cytoprotective mechanisms. Structural data indicated TrPP and MTrPP differ in their molecular weights and structural characteristics with different sugar compositions and side chain ratios. MTrPP was rich in galacturonic acid (687mg/g; TrPP-544mg/g) and galactose (52.9%; TrPP-21.7%). Results were substantiated by NMR/FTIR data indicating the presence of homogalacturonan and rhamnogalacturonam-I containing galactans. By virtue of binding to inflammatory marker (galectin-3), galactans may reduce inflammation induced ulcerations. The low molecular weight of MTrPP (155kDa; TrPP-13kDa) may increase its bioavailability than TrPP, thus MTrPP may possess higher antiulcer potential. Copyright © 2015 Elsevier Ltd.

    Protection of neurons from degeneration is an important preventive strategy for dementia. Much of the dementia pathology implicates oxidative stress pathways. Turmeric (Curcuma longa L.) contains curcuminoids which has anti-oxidative and neuro-protective effects. These effects are considered to be similar to those of citicoline which has been regularly used as one of standard medications for dementia. This study aimed at investigating the effects of turmeric rhizome extract on the hippocampus of trimethyltin (TMT)-treated Sprague-Dawley rats. The rats were divided randomly into six groups, i.e., a normal control group (N); Sn group, which was given TMT chloride; Sn-Cit group, which was treated with citicoline and TMT chloride; and three Sn-TE groups, which were treated with three different dosages of turmeric rhizome extract and TMT chloride. Morris water maze test was carried out to examine the spatial memory. The estimated total number of CA1 and CA2-CA3 pyramidal cells was calculated using a stereological method. The administration of turmeric extract at a dose of 200 mg/kg bw has been shown to prevent the deficits in the spatial memory performance and partially inhibit the reduction of the number of CA2-CA3 regions pyramidal neurons. TMT-induced neurotoxic damage seemed to be mediated by the generation of reactive oxygen species and reactive nitrogen species. Turmeric extract might act as anti inflammatory as well as anti-oxidant agent. The effects of turmeric extract at a dose of 200 mg/kg bw seem to be comparable to those of citicoline.

    The study was conducted to determine whether short-term incorporation of organic manures and biofertilizers influence biochemical and microbial variables reflecting soil quality. For the study, soils were collected from a field experiment conducted on turmeric (Curcuma longa L.) involving organic nutrient management (ONM), chemical nutrient management (CNM) and integrated nutrient management (INM). The findings revealed that application of organic manures and biofertilizers (ONM and INM) positively influenced microbial biomass C, N mineralization, soil respiration and enzymes activities. Contrarily, greater metabolic quotient levels in CNM indicated a stressed soil microbial community. Principal component analysis indicated the strong relationship between microbial activity and the availability of labile and easily mineralizable organic matter. The findings imply that even short-term incorporation of organic manures and biofertilizers promoted soil microbial and enzyme activities and these parameters are sensitive enough to detect changes in soil quality due to short-term incorporation of biological fertilizers.

    The species of Zingiberaceae family are characterized for rhizome. Phenolic constituents like curcuminoids and gingerols have had reports of biological activities. Food irradiation is an effective means of preservation, however it is important to ensure that their functional properties are not compromised. The aim of this study was to evaluate the effectiveness of gamma radiation from {sup 60}Co in doses of 0, 5, 10, 15 and 20 kGy on species of Zingiberaceae: turmeric (Curcuma longa L.), ginger (Zingiber officinale Roscoe) and zedoaria (Curcuma zedoaria (Christm.) Roscoe). The qualitative determination of bioactive compounds profile was performed by thin layer chromatography. The quantification of phenolic compounds was performed by Folin-Ciocalteu method and assessing the potential of antioxidant activity by the free radical [2,2 difenil-1-pricril-hydrazyl (DPPH.] scavenging and by Rancimat method. The curcumin and 6-gingerol quantification was performed by High Performance Liquid Chromatography. Compared to control, there were significant losses of total phenolic compounds in turmeric samples irradiated with 15kGy and 20kGy. There were significant decreases in the ability to scavenge DPPH in irradiated ginger extracts and zedoaria extract irradiated with 20kGy. The Antioxidant Activity Index was significantly lower in 5kGy and 15kGy irradiated turmeric extracts and in irradiated zedoaria extracts. The curcumin quantification was significantly lower in 15kGy irradiated turmeric extracts and there was no significant difference in the 6-gingerol quantification between ginger extracts. It is concluded that gamma radiation processing technology in Zingiberaceae can be viable for industry. To maintain safety of antioxidant activity it should be applied doses up 10kGy. (author)

    Turmeric (Curcuma longa L.) belongs to the family Zingiberaceae that is widely used as a spice in food preparations in addition to its biological activities. UV, FT-IR, 1 H NMR in addition to HPLC were applied to construct a metabolic fingerprint for Turmeric in an attempt to assess its quality. 30 samples were analyzed, and then principal component analysis (PCA) and hierarchical clustering analysis (HCA) were utilized to assess the differences and similarities between collected samples. PCA score plot based on both HPLC and UV spectroscopy showed the same discriminatory pattern, where the samples were segregated into four main groups depending on their total curcuminoids content. The results revealed that UV could be utilized as a simple and rapid alternative for HPLC. However, FT-IR failed to discriminate between the same species. By applying 1 H NMR, the metabolic variability between samples was more evident in the essential oils/fatty acid region. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The recent development of fused-core technology in HPLC columns is enabling faster and highly efficient separations. This technology was evaluated for the development of a fast method for the analysis of main curcuminoids (curcumin, demethoxycurcumin and bisdemethoxycurcumin) present in extracts of turmeric (Curcuma longa L.). A step-by-step strategy was used to optimize temperature (40-55 °C), flow rate (1.0-2.5 mL min(-1)), mobile phase composition and equilibration time (1-5 min). A gradient method was developed using acidified water and acetonitrile combined with high column temperature (55 °C) and flow rate (2.5 mL min(-1)). Optimized conditions provided a method for the separation of these three curcuminoids in approximately 1.3 min with a total analysis time (sample-to-sample) of 7 min, including the clean-up and the re-equilibration of the column. Evaluation of chromatographic performance revealed excellent intraday and interday reproducibility (>99%), resolution (>2.23), selectivity (>1.12), peak symmetry (1.24-1.42) while presenting low limits of detection (<0.40 mg L(-1)) and quantification (<1.34 mg L(-1)). The robustness of the method was calculated according to the concentration/dilution of the sample and the injection volume. Several combinations of methanol and ethanol with water as sample solvents were evaluated and the best chromatographic results and extraction rate were obtained using 100% methanol. Finally, the developed method was validated with different extracts of turmeric rhizome and products that use turmeric in their formulation. Copyright © 2016 Elsevier Ltd. All rights reserved.

    As the use of herbal medications continues to increase in America, the potential interaction between herbal and prescription medications necessitates the discovery of their mechanisms of action. The purpose of this study was to investigate the anxiolytic and antidepressant effects of curcumin, a compound from turmeric (Curcuma longa), and its effects on the benzodiazepine site of the γ-aminobutyric acid receptor A (GABAA) receptor. Utilizing a prospective, between-subjects group design, 55 male Sprague-Dawley rats were randomly assigned to 1 of the 5 intraperitoneally injected treatment groups: vehicle, curcumin, curcumin + flumazenil, midazolam, and midazolam + curcumin. Behavioral testing was performed using the elevated plus maze, open field test, and forced swim test. A 2-tailed multivariate analysis of variance and least significant difference post hoc tests were used for data analysis. In our models, curcumin did not demonstrate anxiolytic effects or changes in behavioral despair. An interaction of curcumin at the benzodiazepine site of the GABAA receptor was also not observed. Additional studies are recommended that examine the anxiolytic and antidepressant effects of curcumin through alternate dosing regimens, modulation of other subunits on the GABAA receptor, and interactions with other central nervous system neurotransmitter systems.

    Curcuma longa L., accumulates substantial amount of curcumin and essential oil. Little is known about the differential expression of curcumin synthase (CURS) gene and consequent curcumin content variations at different agroclimatic zones. The present study aimed to evaluate the effect of climate, soil and harvesting phase on expression of CURS gene for curcumin yield in two high yielding turmeric cultivars. Expression of CURS gene at different experimental zones as well as at different harvesting phase was studied through transcriptional analysis by qRT-PCR. Curcumin varied from 1.5 to 5% and 1.4-5% in Surama and Roma respectively. The expression of CURS also varied from 0.402 to 5.584 fold in Surama and 0.856-5.217 fold in Roma. Difference in curcumin content at a particular zone varied among different harvesting period from 3.95 to 4.31% in Surama and 3.57-3.83% in Roma. Expression of CURS gene was also effected by harvesting time of the rhizome which varied from 7.389 to 16.882 fold in Surama and 4.41-8.342 fold in Roma. The CURS gene expression was found regardless of variations in curcumin content at different experimental zones. This may be due to the effects of soil and environmental variables. Expression was positively correlated with curcumin content with different harvesting time at a particular zone. This find indicates effect of soil and environment on molecular and biochemical dynamics of curcumin biosynthesis and could be useful in genetic improvement of turmeric.

The first group was used as control, while groups 2, 3, and 4 were treated with turmeric powder (T, 50 mg/kg body weight/day), sodium arsenite (Sa, 10 mg/kg body weight/day) and turmeric plus Sa (T+Sa), respectively. Results showed that oral administration of Sa reduced the weight gain of the mice compared to the control group and food supplementation of turmeric prevented the reduction of weight gain. Turmeric abrogated the Sa-induced elevation of serum urea, glucose, triglyceride (TG) level and alanine aminotransferase (ALT) activity except the activity of alkaline phosphatase (ALP). Turmeric also prevented the Sa-induced perturbation of serum butyryl cholinesterase activity (BChE). Therefore, ameliorating effect of turmeric on Sa-treated mice suggested the future application of turmeric to reduce or to prevent arsenic toxicity in human.

    Turmeric is a rhizomatous herbaceous perennial but cultivated as annual, belonging to the family Zingiberaceae. It is a native of India and South East Asia. The tuberous rhizomes or underground stems of turmeric are used from antiquity as condiments, a dye and as an aromatic stimulant in several medicines. Turmeric is an important crop in India and it is used as a spice, food preservative, coloring agent, cosmetic as well as for its medicinal properties. Propagation is done vegetatively with rhizome bits as seed materials. It is plagued by rhizome rot diseases most of which are mainly spread through infected seed rhizomes. Micropropagation will help in production of disease-free seed. Sexual reproduction is rare in turmeric, making recombinant breeding very difficult. In vitro technology can thus become the preferred choice and it can be utilized for multiplication, conservation of genetic resources, generating variability, gene transfer, molecular tagging, and their utility in crop improvement.

    Aflatoxins as potent mycotoxins can influence vital parameters in chickens. Turmeric was used in decreasing toxic effect of mycotoxins on vital organs, traditionally. The study compared the protective effect of turmeric and Mycoad(TR) in broilers exposed to aflatoxin. Chickens (270) were divided into six groups. The chickens were fed a basal diet, turmeric extract (5 mg/kg diet), Mycoad(TR) (25 mg/kg diet), productive aflatoxin (3 mg/kg diet), aflatoxin plus turmeric extract (3 versus 5 mg/kg diet), and aflatoxin plus Mycoad(TR) (3 versus 25 mg/kg diet) in basal diet. At 28 d old, we determined plasma concentration of total protein, albumin, triglyceride, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), calcium, potassium, phosphorous, uric acid, aspartate transferase (AST), and alanine aminotransferase (ALT). Furthermore, liver and kidney were sampled for pathological examination. Chickens fed turmeric with aflatoxin had significant lower ALT, AST, and uric acid than chickens fed aflatoxin (11.4 ± 0.79, 228 ± 9, and 6 ± 0.4 versus 17.2 ± 1.7, 283 ± 5, and 7.7 ± 0.1) whereas, total protein, calcium, and HDL values in chickens fed aflatoxin plus turmeric increased significantly (2.66 ± 0.16, 8.4 ± 0.2, and 920 ± 4.1 versus 1.7 ± 0.17, 7 ± 0.2, and 690 ± 4.8). Pathological examination revealed severe congestion, degeneration, and necrosis in liver and kidney in chickens that received aflatoxin. The study showed that turmeric may provide protection against the toxic effects of aflatoxin on liver and kidney.

    Full Text Available Inflammatory bowel disease (IBD is a chronic relapsing disease. Genetic predisposition to the disease reduces an individual’s capacity to respond appropriately to environmental challenges in the intestine leading to inappropriate inflammation. IBD patients often modify their diet to mitigate or reduce the severity of inflammation. Turmeric (Curcuma longa L., Zingiberaceae has historically been used in Chinese, Hindu, and Ayurvedic medicine over several centuries to treat inflammatory disorders. To understand how turmeric may influence the consequences of a genetic predisposition to inappropriate inflammation, we used HEK293 cells to examine the in vitro capacity of turmeric extract and fractions to affect the functionality of two gene variants, solute carrier protein 22 A4 (SLC22A4, rs1050152 and interleukin-10 (IL-10, rs1800896 associated with IBD. We found that a turmeric extract and several chromatographically separated fractions beneficially affected the variants of SLC22A4 and IL-10 associated with IBD, by reducing inappropriate epithelial cell transport (SLC22A4, 503F and increasing anti-inflammatory cytokine gene promoter activity (IL-10, −1082A. The effect of turmeric on the IL-10 variant was strongly associated with the curcumin content of the extract and its fractions.

    Singh, Noopur; Sharma, Ashok

    Turmeric has been used as a therapeutic herb over centuries in traditional medicinal systems due to the presence of several secondary metabolite compounds. microRNAs are known to regulate gene expression at the post-transcriptional level by transcriptional cleavage or translation repression. miRNAs have been demonstrated to play an active role in secondary metabolism regulation. The present work was focused on the identification of the miRNAs involved in the regulation of secondary metabolite and development process of turmeric. Eighteen miRNA families were identified for turmeric. Sixteen miRNA families were observed to regulate 238 target transcripts. LncRNAs targets of the putative miRNA candidates were also predicted. Our results indicated their role in binding, reproduction, stress, and other developmental processes. Gene annotation and pathway analysis illustrated the biological function of the targets regulated by the putative miRNAs. The miRNA-mediated gene regulatory network also revealed co-regulated targets that were regulated by two or more miRNA families. miR156 and miR5015 were observed to be involved in rhizome development. miR5021 showed regulation for terpenoid backbone biosynthesis and isoquinoline alkaloid biosynthesis pathways. The flavonoid biosynthesis pathway was observed to be regulated by miR2919. The analysis revealed the probable involvement of three miRNAs (miR1168.2, miR156b and miR1858) in curcumin biosynthesis. Other miRNAs were found to be involved in the growth and developmental process of turmeric. Phylogenetic analysis of selective miRNAs was also performed. Copyright © 2017 Académie des sciences.

    This project presents the effects of turmeric (Curcuma Longa) on the functionality of pigmentation was carried out to improve the sustainability, environment impact and reduction of potential cost saving without sacrificing the performance of thin film coating. The Curcuma Longa pigment was extracted by grating the turmeric into small particles at different percentages which is 20%, 40%, 60% and 80% of Curcuma Longa pigment with 3, 6 and 9 layers of coating. The different percentages of Curcuma Longa pigment was formulated and synthesized with polyols by crosslinking agent of glycerol and calcium carbonate into temperature at 140 °C for 2 hours. The results of water droplet test (ASTM D5964) showed the water contact angle was achieved the optimum superhydrophobic characteristic up to 60% of Curcuma Longa at 153°. The formulation of 60% Curcuma Longa was revealed the optimum adhesion resistance test with no flaking and detachment when the coating applied at 9 layers in the classification grading of adhesion test at 5B. It is indicated that the adhesion resistance of thin film coating on metal substrate was obviously increased as the layer of coating as well as the Curcuma Longa pigment percentage up to 60% at 9 layers. This project also highlighted the potential of Curcuma Longa pigment to produce quality in the natural pigmentation as a replacement synthetic pigment which is long-term health hazards.

    Turmeric extracts were obtained from two lots of raw material (M and S) using various techniques: hydrodistillation, low pressure solvent extraction, Soxhlet, and supercritical extraction using carbon dioxide and cosolvents. The solvents and cosolvents tested were ethanol, isopropyl alcohol, and their mixture in equal proportions. The composition of the extracts was determined by gas chromatography-flame ionization detection (GC-FID) and UV. The largest yield (27%, weight) was obtained in the Soxhlet extraction (turmeric (S), ethanol = 1:100); the lowest yield was detected in the hydrodistillation process (2.1%). For the supercritical extraction, the best cosolvent was a mixture of ethanol and isopropyl alcohol. Sixty percent of the light fraction of the extracts consisted of ar-turmerone, (Z)-gamma-atlantone, and (E)-gamma-atlantone, except for the Soxhlet extracts (1:100, ethanol), for which only ar-turmeronol and (Z)-alpha-atlantone were detected. The maximum amount of curcuminoids (8.43%) was obtained using Soxhlet extraction (ethanol/isopropyl alcohol). The Soxhlet and low pressure extract exhibited the strongest antioxidant activities.

    Herbal medicine value chains have generally been overlooked compared with food commodities. Not surprisingly, revenue generation tends to be weighted towards the end of the chain and consequently the farmers and producers are the lowest paid beneficiaries. Value chains have an impact both on the livelihood of producers and on the composition and quality of products commonly sold locally and globally and consequently on the consumers. In order to understand the impact of value chains on the composition of products, we studied the production conditions for turmeric (Curcuma longa) and the metabolomic composition of products derived from it. We aimed at integrating these two components in order to gain a better understanding of the effect of different value chains on the livelihoods of some producers. This interdisciplinary project uses a mixed methods approach. Case studies were undertaken on two separate sites in India. Data was initially gathered on herbal medicine value chains by means of semi-structured interviews and non-participant observations. Samples were collected from locations in India, Europe and the USA and analysed using (1)H NMR spectroscopy coupled with multivariate analysis software and with high performance thin layer chromatography (HPTLC). We investigate medicinal plant value chains and interpret the impact different value chains have on some aspects of the livelihoods of producers in India and, for the first time, analytically assess the chemical variability and quality implications that different value chains may have on the products available to end users in Europe. There are benefits to farmers that belonged to an integrated chain and the resulting products were subject to a higher standard of processing and storage. By using analytical methods, including HPTLC and (1)H NMR spectroscopy, it has been possible to correlate some variations in product composition for selected producers and identify strengths and weaknesses of some types of value

    Full Text Available The root knot nematodes can reduce yield potential of plants, thus requiring searching control methods that are effective and eco-friendly. The purpose of this study was to analyze the efficiency of turmeric rhizome aqueous extract (Curcuma longa on hatching, immobilization and mortality of juveniles of Meloidogyne incognita. A completely randomized design was used, with concentrations of 1%, 5%, 10% and 15% of turmeric extract and distilled water as a control treatment, with four replications. The juveniles of nematodes were directly exposed to turmeric extract for 24 h, while eggs were exposed during 15 days. The turmeric extract on J2 of Meloidogyne incognita, in vitro tests, promoted from the concentration of 10% total paralysis of nematodes and in the concentration of 15% more than 90% mortality. All tested concentrations caused reduction in juveniles hatching. Thereby, the turmeric aqueous extract has nematicidal potential against M. incognita, encouraging its study in the interaction plant-nematode.

    Osteoarthritis (OA) is a chronic inflammatory degenerative process that affects joints such as the hands, hips, shoulders, feet, spine, and especially knees in millions of people worldwide. Some authors have shown that Curcuma longa components may exhibit benefic effects in the treatment of degenerative diseases as OA. This plant belongs to the family Zingiberaceae and it is popularly known as turmeric or saffron. This review intended to perform a retrospective search to identify studies involving humans and animal models. This review was based on articles linking OA and C. longa. Databases as Medline, Science Direct, and Lilacs were consulted and a retrospective search was carried out in order to identify studies involving humans and animal models. The curcuminoids from C. longa exhibit actions at different locations in the pathogenesis of OA once it may play an important role as anti-inflammatory, down-regulating enzymes as phospholipase A2, cyclooxygenase-2, and lipoxygenases, and reducing tumor necrosis factor-alpha-and interleukins such as interleukin-1β (IL-1β), IL-6, and IL-8. They also act as inducer of apoptosis in synoviocytes, decreasing the inflammation process and may also reduce the synthesis of reactive oxygen species. For these reasons, new pharmaceutical technology and pharmacological studies should be proposed to determine the dose, the best delivery vehicle, pharmaceutical formulation and route of administration of this plant so its use as an adjunct in the treatment of OA may become a reality in clinical practice.

    Cucuma longa Linn. (Fam-Zingiberaceae) is a valued medicinal plant contains curcuminoids (curcumin, demethoxycurcumin and bisdemethoxycurcumin) as major bioactive constituents. Previously reported analytical methods for analysis of curcuminoids were found to suffer from low resolution, lower sensitivity and longer analytical times. In this study, a rapid, sensitive, selective high-throughput ultra high performance liquid chromatography-tandem mass spectrometry (UPLC/Q-TOF-MS) method was developed and validated for the quantification of curcuminoids with an aim to reduce analysis time and enhance efficiency. UPLC/Q-TOF-MS analysis showed large variation (1.408-5.027% w/w) of curcuminoids among different samples with respect to their occurrence of metabolite and their concentration. The results showed that Erode (south province) contains highest quantity of curcuminoids and concluded to be the superior varieties. The results obtained here could be valuable for devising strategies for cultivating this medicinal plant. © The Author 2015. Published by Oxford University Press. All rights reserved.

    A study was conducted to determine the efficacy of bentonite clay (BC), diatomaceous earth (DE) and turmeric powder (TUM) in alleviating the toxic effects of aflatoxin B1 (AFB1). A total of 250 Ross-308 d-old male broiler chicks were assigned to 10 dietary treatments (5 replicates of 5 chicks) from hatch to d 21. Dietary treatments were: basal diet; basal diet plus AFB1 (2 mg) or BC (0.75%), or DE (0.75%), or TUM (200 mg/kg curcuminoids) and different combinations of AFB1, BC, DE and TUM. Feed intake (FI), body weight gain (BWG) and feed gain (FG) of the birds fed on BC or DE separately were not different from control birds. Birds fed on TUM only had similar FI and FG but lower BWG than control chicks. Aflatoxin B1 reduced FI, BWG and serum concentrations of glucose, albumin, total protein calcium, but increased FG and relative liver and kidney weights. Chicks fed on the combination of AFB1 and BC had similar FI and FG to control chicks. Chicks fed on the combination of DE and AFB1 had lower FI (23.1%) and BWG (28.6%) compared with control chicks. Chicks fed on the combination of TUM and AFB1 also had decreased FI (26.2 %) and BWG (31%) compared with control chicks. Chicks fed on the combination of AFB1, BC and TUM consumed significantly higher amounts of feed compared with chicks fed on only AF, but gained less when compared with control diet chicks. Chicks fed on the combination of AFB1, DE and TUM diet had poorer growth performance than those fed on AFB1 alone. None of the combination diets reduced the severity of liver lesions.

    The aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.83 ± 0.04 g) were fed, for 60 days, with six diets containing 0.0, 20.0, 40.0, 60.0, 80.0, and 100.0 g turmeric kg -1 feed. There was an increasing linear effect of turmeric on the thickness of the muscular layer, and height and width of the folds of the intestine. In the liver, a quadratic effect was observed of turmeric on the percentage of hepatocyte cytoplasm and a decreasing linear effect on the percentage of sinusoid capillaries. A quadratic effect was also observed of turmeric on the liver glycogen. There was no effect of turmeric on the antioxidant activity in the liver, carcass composition or productive performance of the fish. Thus, we concluded that Curcuma longa has trophic effects on the epithelium and the muscular layer of the intestine of A. aff. bimaculatus. Additionally, low levels of Curcuma longa cause increased deposition of liver glycogen and high levels cause reduction.

Body weight gain, feed consumption, feed conversion ratio were investigated throughout the experimental period, and bloody diarrhea and oocysts excretions were investigated at the first and the second week after infection. Maximum coccidiostatic effect was observed with turmeric (3% showing mild bloody diarrhea as compared to other infected groups receiving turmeric containing rations. This effect was comparable with a standard coccidiostat i.e., salinomycin sodium. Similarly, the weight gain in the groups treated with salinomycin sodium (2280g and 3% turmeric (2293g were also significantly higher (p < 0.05 than that of infected control group (1955g. In the groups treated with ration supplemented with 3% turmeric powder and salinomycin sodium, the peak excretion of oocysts was delayed about 1 or 2 days relative to the control infected group. Concentration-dependent coccidiostatic effect of turmeric suggested that further studies should be carried out to determine the possible maximum safe levels of turmeric with least toxic effects to be used as coccidiostat.

    Full Text Available A total of 240 Ross 308 day-old male broiler chicks within a completely randomized design were used in this experiment to evaluate the effects of dietary inclusion of turmeric powder and cinnamon powder on performance and some immune responses of broiler chickens. Dietary treatments were as follow: a corn-soybean meal basal diet (control; basal diet + 10 ppm avilamycin; basal diet + 2.5 g/Kg turmeric powder; basal diet + 7.5 g/Kg turmeric powder; basal diet + 2.5 g/Kg cinnamon powder; and basal diet + 7.5 g/Kg cinnamon powder. During the experiment, feed intake, body weight gain, and feed conversion ratio were measured in the beginning and the end of starter (0-21 d. and grower (22-42 d. periods. On 21 d. of age, two chicks from each replicate were randomly selected and blood samples were taken. Differential enumeration of heterophils, lymphocytes, and monocytes were done. Also, antibody titers against IBV, IBD, and NDV vaccines were measured. Addition of 2.5 g/Kg turmeric powder increased body weight gain in the starter period and improved feed conversion ratio in the starter and entire periods of the experiment, when compared to the control (P. Also, inclusion of 10 ppm avilamycin into diet improved feed conversion ratio in the grower and entire periods of the experiment, comparing to the control (P. Inclusion of turmeric powder at 2.5 g/Kg or 7.5 g/Kg and cinnamon powder at 7.5 g/Kg declined the heterophil to lymphocyte ratio (P. The results of this study showed that turmeric powder at the level of 2.5 g/Kg would be a potential alternative for antibiotic growth promoters.

    Full Text Available Buds from rhizomes of Curcuma longa L. variety ‘Chumphon’ and Curcuma mangga Valeton & Zijp variety ‘Phetchaburi’ were cultured on Murashige and Skoog (MS medium supplemented with 2.0 mg/L N6-benzyladenine (BA for multiple shoot induction. Their shoots were cultured on MS medium supplemented with various concentrations of one of two plant growth regulators or a combination of both—2,4-dichlorophenoxyacetic acid (2,4-D and naphthaleneacetic acid (NAA. Interestingly, the medium containing both auxins (5 mg/L 2,4-D and 5 mg/L NAA was best for somatic embryo induction after culturing for 4 weeks. Somatic embryo formation reached 87.50% for Curcuma longa and 95.83% for Curcuma mangga with a high quality of loose, friable and yellowish characters. The best conditions for the formation of shootlets occurred after transferring the somatic embryo to MS medium supplemented with 3.0 mg/L BA, 0.5 mg/L NAA and 3% maltose. The shootlets were rooted by transferring to MS medium containing 3.0 mg/L NAA. This is the first report of a complete in vitro regeneration system from somatic embryos of C. longa and C. mangga which was further used for gene manipulation in these plants. Diketide CoA synthase (DCS and curcumin synthase (CURS genes, which are the two genes involved in curcuminoid biosynthesis in turmeric, were cloned and transferred to these two species using Agrobacterium-mediated transformation. The presence of both target and marker genes, hpt, in the transformed somatic embryos was confirmed by polymerase chain reaction assay. After culturing, the transformed somatic embryos could survive for 4 weeks.

    We investigated the fingerprints of 48 batches of turmeric total extracts (TTE) by HPLC-MS-MS and GC-MS analyses and 43 characteristic peaks (22 constituents from HPLC-MS-MS; 21 from GC-MS) were analyzed qualitatively and quantitatively. An MTT {3-(4,5-dimethylthiazol-2-yl)- 2,5-diphenyltetrazolium bromide} assay was implemented to measure the cytotoxicity of the TTE against HeLa cells. Then we utilized orthogonal partial least squares analysis, which correlated the chemical composition of the TTE to its cytotoxic activity, to identify potential cytotoxic constituents from turmeric. The result showed that 19 constituents contributed significantly to the cytotoxicity. The obtained result was verified by canonical correlation analysis. Comparison with previous reports also indicated some interaction between the curcuminoids and sesquiterpenoids in turmeric.

    Turmeric (rich in curcuminoids) and ginger (rich in gingerols and shogaols) rhizomes have been widely used as dietary spices and to treat different diseases in Ayurveda/Chinese medicine since antiquity. Here, we compared the anti-inflammatory/anti-oxidant activity of these two plants in rat adjuvant-induced arthritis (AIA). Both plants (at dose 200 mg/kg body weight) significantly suppressed (but with different degrees) the incidence and severity of arthritis by increasing/decreasing the production of anti-inflammatory/pro-inflammatory cytokines, respectively, and activating the anti-oxidant defence system. The anti-arthritic activity of turmeric exceeded that of ginger and indomethacin (a non-steroidal anti-inflammatory drug), especially when the treatment started from the day of arthritis induction. The percentage of disease recovery was 4.6-8.3% and 10.2% more in turmeric compared with ginger and indomethacin (P turmeric over ginger and indomethacin, which may have beneficial effects against rheumatoid arthritis onset/progression as shown in AIA rat model.

    Anorexia is a common symptom for patients with advanced cancer. Gentian, ginger, and turmeric have traditionally been used to stimulate appetite. We tested these agents in combination, in a pilot study to assess tolerability in patients indicating 4/10 or worse anorexia on the Edmonton Symptom Assessment System, and who were not currently on chemotherapy. We collected exploratory data on the patient's appetite using a visual analogue scale. Between 2009 and 2012, 17 patients were enrolled in arm 1 (turmeric 1 g and ginger 1 g orally twice daily, and gentiana lutea tincture 1 mL three times a day, for 14 days). The three patients enrolled in arm 2 received the same doses of ginger and turmeric but no gentian. All patients completed a daily appetite diary and a weekly symptom assessment. In arm 1, seven patients (41%) completed treatment. Seven patients (41%) stopped early because of unacceptable toxicity or patient-initiated discontinuation, and 3 stopped because of other reasons. All patients in arm 2 stopped taking the study medication within few days of starting the treatment, leading the study committee to recommend stopping the trial. The most common adverse effects attributed to study drugs were nausea (6 patients), vomiting (3), fatigue (3), diarrhea (2) and bloating (2). There was no statistically significant effect seen on appetite. At the doses used in this study, the combination of ginger, turmeric, and gentian is not tolerated well in cancer patients. Future studies should use fewer agents or lower doses.

    The commercially available dry turmeric powder at 10.34% d.b. moisture content was decontaminated using microwaves at high power density for short time. To avoid the loss of moisture from turmeric due to high microwave power, the drying kinetics were modelled and considered during optimization of microwave decontamination process. The effect of microwave power density (10, 33.5 and 57 W g -1 ), exposure time (10, 20 and 30 s) and thickness of turmeric layer (1, 2 and 3 mm) on total plate, total yeast and mold (YMC) counts, color change (∆E), average final temperature of the product (T af ), water activity (a w ), Page model rate constant (k) and total moisture loss (ML) was studied. The perturbation analysis was carried out for all variables. It was found that to achieve more than one log reduction in yeast and mold count, a substantial reduction in moisture content takes place leading to the reduced output. The microwave power density significantly affected the YMC, T af and a w of turmeric powder. But the thickness of sample and microwave exposure time showed effect only on T af , a w and ML. The colour of turmeric and Page model rate constant were not significantly changed during the process as anticipated. The numerical optimization was done at 57.00 W g -1 power density, 1.64 mm thickness of sample layer and 30 s exposure time. It resulted into 1.6 × 10 7 CFU g -1 YMC, 82.71 °C T af , 0.383 a w and 8.41% (d.b.) final moisture content.

    Acute monocytic leukemia (AML M5 or AMoL) is one of the several types of leukemia that are still awaiting cures. The use of chemotherapy for cancer management can be harmful to normal cells in the vicinity of the target leukemia cells. This study assessed the potency of the extracts from lesser galangal, turmeric, and ginger against AML M5 to use the suitable fractions in neutraceuticals. Aqueous and organic solvent extracts from the leaves and rhizomes of lesser galangal and turmeric, and from the rhizomes only of ginger were examined for their antiproliferative activities against THP-1 AMoL cells in vitro. Lesser galangal leaf extracts in organic solvents of methanol, chloroform, and dichloromethane maintained distinctive antiproliferative activities over a 48-h period. The turmeric leaf and rhizome extracts and ginger rhizome extracts in methanol also showed distinctive anticancer activities. The lesser galangal leaf methanol extract was subsequently separated into 13, and then 18 fractions using reversed-phase high-performance liquid chromatography. Fractions 9 and 16, respectively, showed the greatest antiproliferative activities. These results indicate that the use of plant extracts might be a safer approach to finding a lasting cure for AMoL. Further investigations will be required to establish the discriminatory tolerance of normal cells to these extracts, and to identify the compounds in these extracts that possess the antiproliferative activities.

    Full Text Available The aim of this study was to evaluate the effects of turmeric powder and ascorbic acid on lipid oxidation and antioxidant capacity in cooked rabbit burgers. The burgers were derived from 3 different formulations (C, control, with no additives; Tu with 3.5% of turmeric powder and AA with 0.1% of ascorbic acid and were stored at 4°C for 0 and 7 d and cooked. The lipid oxidation (thiobarbituric acid reactive substances [TBARS] and antioxidant capacity (2,2-azinobis-[3 ethylbenzothiazoline-6-sulfonic acid] {ABTS}, 1,1-diphenyl-2-pircydrazyl [DPPH] and ferric reducing ability [FRAP] were evaluated. A significant interaction between storage time and formulation (P<0.001 was observed for DPPH, FRAP and TBARS in cooked burgers. At day 0 and day 7, the DPPH value was higher in Tu and AA compared to C burgers. At day 0, C showed a lower level of FRAP than the Tu and AA burgers. At day 7, the FRAP values tended to decrease but remained significantly higher in Tu and AA compared to C burgers. Lipid oxidation at day 0 in Tu and AA showed lower TBARS values compared to C burgers. The addition of 3.5% turmeric powder in rabbit burgers exerts an antioxidant effect during storage and it seems more effective in controlling lipid oxidation than ascorbic acid after cooking.

  8. Modules of co-regulated metabolites in turmeric (Curcuma longa) rhizome suggest the existence of biosynthetic modules in plant specialized metabolism.

    Turmeric is an excellent example of a plant that produces large numbers of metabolites from diverse metabolic pathways or networks. It is hypothesized that these metabolic pathways or networks contain biosynthetic modules, which lead to the formation of metabolite modules-groups of metabolites whose production is co-regulated and biosynthetically linked. To test whether such co-regulated metabolite modules do exist in this plant, metabolic profiling analysis was performed on turmeric rhizome samples that were collected from 16 different growth and development treatments, which had significant impacts on the levels of 249 volatile and non-volatile metabolites that were detected. Importantly, one of the many co-regulated metabolite modules that were indeed readily detected in this analysis contained the three major curcuminoids, whereas many other structurally related diarylheptanoids belonged to separate metabolite modules, as did groups of terpenoids. The existence of these co-regulated metabolite modules supported the hypothesis that the 3-methoxyl groups on the aromatic rings of the curcuminoids are formed before the formation of the heptanoid backbone during the biosynthesis of curcumin and also suggested the involvement of multiple polyketide synthases with different substrate selectivities in the formation of the array of diarylheptanoids detected in turmeric. Similar conclusions about terpenoid biosynthesis could also be made. Thus, discovery and analysis of metabolite modules can be a powerful predictive tool in efforts to understand metabolism in plants.

    The aim of this study was to evaluate the protective effects of the turmeric in comparison to vitamin E on bursal damages induced by salinomycin in broiler chickens. In this study, forty one day-old broiler chicks were randomly divided into four treatment groups: 1- basal diet as control, 2- basal diet plus salinomycin, 3- basal diet plus salinomycin (SLM) and vitamin E (Vit. E) and 4- basal diet plus salinomycin and turmeric powder. The chicks were treated for two weeks. At the end of the experiment, the bursal tissues were removed and fixed in 10% formalin solution. Tissue sections were stained with hematoxylin and eosin stain for histopathological studies. Light microscopic observations showed that, SLM diminished cortex thickness of bursal tissue, enhanced its medulla zone and caused severe lymphocytic necrosis. In addition, SLM led to fibrosis of interstitium along with sever edema of medulla zone in the bursal tissue of the chicken. Administration of Vit. E and TP significantly inhibited the SLM-induced derangements and comparing the Vit. E and TP showed no significant differences. The results of this study indicated that the turmeric may protect bursa of Fabricius against toxicity induced by salinomycin in chicks.

    Although leaves of Curcuma mangga and Curcuma longa are used in food preparations, the bioactive components in it are not known. In this study, antioxidant, antiinflammatory and anticancer activities of leave extracts and its isolates were investigated using established bioassay procedures in our laboratory. The leaf extracts of both plants gave similar bioassay and chromatographic profiles. The methanolic and water extracts of C. mangga (CMM and CMW) and C. longa (CLM and CLW), at 100 μg/mL, inhibited lipid peroxidation (LPO) by 78%, 63%, 81% and 43%, cyclooxygenase enzymes COX-1 by 55%, 33%, 43% and 24% and COX-2 by 65%, 55%, 77% and 69%, respectively. At same concentration, CMM, CMW, CLM and CLW showed growth inhibition of human tumour cell lines by 0-46%. Therefore, a bioassay-guided isolation of water and methanolic extracts of C. longa was carried out and afforded nine isolates. At 25 μg/mL, these compounds inhibited LPO by 11-87%, COX-1 and -2 enzymes by 0-35% and 0-82% and growth of human tumour cells by 0-36%, respectively. Copyright © 2012 Elsevier Ltd.

    Curcumin (diferuloylmethane) is an orange-yellow secondary metabolic compound from the rhizome of turmeric (Curcuma longa L.), a spice often found in curry powder. It is one of the major curcuminoids of turmeric. For centuries, curcumin has been used in some medicinal preparations or as a food colouring agent. A variety of enzymes that are closely associated with inflammation and cancer were found to be modulated by curcumin. This paper summarized the results of the inhibitory effect of curcumin and a Curcuma longa L. ethanolic extract on lipoxygenase from the rat lung cytosolic fraction. The positional specificity determination of arachidonic acid dioxygenation by RP- and SP-HPLC methods showed that in a purified enzyme preparation from the rat lung cytosol the specific form of lipoxygenase (LOX) is present exhibiting 12/15-LOX dual specificity (with predominant 15-LOX activity). The inhibitory activity of curcumin and Curcuma longa extract on LOX from cytosolic fraction of rat lung was expressed in the percentage of inhibition and as IC50. Lineweaver-Burk plot analysis has indicated that curcumin is the competitive inhibitor of 12/15 LOX from the rat lung cytosolic fraction.

    2016-01-01

    BACKGROUND/OBJECTIVES Turmeric (Curcuma longa L.) has been reported to have many biological functions including anti-obesity. Leptin, peptide hormone produced by adipocytes and its concentration is increased in proportion to the amount of the adipocytes. In the present study, we examined the effects of Korean turmeric on the regulation of adiposity and leptin levels in 3T3-L1 adipocytes and rats fed a high-fat and high-cholesterol diet. MATERIALS/METHODS Leptin secretion, free fatty acid and glycerol contents in 3T3-L1 adipocytes were measured after incubation of cells with turmeric for 24 hours. Rats were divided into four experimental groups: a normal diet group (N), a high-fat and high-cholesterol diet group (HF), a high-fat and high-cholesterol diet group supplemented with 2.5% turmeric extracts (TPA group) and a high-fat and high-cholesterol diet group supplemented with 5% turmeric extracts (TPB group). Serum samples were used for the measurement of leptin concentration. RESULTS Contents of free fatty acid and glycerol showed concentration dependent increase in response to turmeric extracts. Effects of turmeric extracts on reduction of lipid accumulation in 3T3-L1 cells were examined by Oil Red O staining. Treatment with turmeric extracts resulted in increased expression levels of adipose triglyceride lipase and hormone-sensitive lipase mRNA. The concentration of leptin from 3T3-L1 adipocytes was significantly decreased by turmeric. Proportional abdominal and epididymal fats weights of the turmeric 5% supplemented group, TPB has significantly decreased compared to the HF group. The serum levels of leptin in the TPA and TPB groups were significantly lower than those of the HF group. CONCLUSIONS Based on these results, we suggested that Korean turmeric may contribute to the decreasing of body fat and regulating leptin secretion. PMID:27698955

    Crude ethanolic extract and column chromatographic fractions of the Allepey cultivar of Curcuma longa Roxb, commonly called turmeric (tumeric) in commerce, were used as a stain for tissue sections. Staining was carried out under basic, acidic and neutral media conditions. Inorganic and organic dissolution solvents were used. The stain was used as a counterstain after alum and iron haematoxylins. C. longa stained collagen fibres, cytoplasm, red blood cells and muscle cells yellow. It also stained in a fashion similar to eosin, except for its intense yellow colour. Preliminary phytochemical evaluation of the active column fraction revealed that it contained flavonoids, free anthraquinone and deoxy sugar. A cheap, natural dye can thus be obtained from C. longa.

With the increasing awareness of a green earth, it is advisable to use more of eco-friendly and biodegradable material which can be effectively achieved by the use of natural dyes obtained from plants and other natural sources. Turmeric, available as Curcuma longa (domestic), has long been in use in the subcontinent as a spice and flavoring agent in most food preparations. Its health benefit as a natural antibiotic and anti-inflammatory has been successfully established by several researchers. The intense yellow color imparted by turmeric inspired us to explore its efficacy as a potential alternative for eosin in routine histopathological procedures. The aim of this was to explore the efficacy of turmeric extract as a stand-alone counterstain for hematoxylin and its comparative assessment with routine H and E staining. The rhizomes of C. longa were cut into small pieces, dried and milled. This powder was dissolved into alcohol and centrifuged using a centrifugal machine. The supernatant was then collected with the help of micropipette. This supernatant was used as a counterstain for hematoxylin. The data were analyzed using Mann-Whitney U test with Statistical Package for the Social Sciences version 15.0 (SPSS Inc.,). The P value obtained was statistically insignificant ( P > 0.05). Although eosin is the most efficient counterstain for hematoxylin, turmeric can also be used as an alternative for eosin.

    Curcuma longa (C. longa) was used in some countries such as China and India for various medicinal purposes. Curcumin, the active component of C. longa, is commonly used as a coloring agent in foods, drugs, and cosmetics. C. longa and curcumin have been known to act as antioxidant, anti-inflammatory, anti-mutagen, and anti-carcinogenic agents. Th e attempt of the present review was to give an effort on a detailed literature survey concentrated on the protective effects of C. longa and curcumin on the reproductive organs activity. The databases such as, PubMed, Web of Science, Google Scholar, Scopus, and Iran- Medex, were considered. The search terms were "testis" or "ovary" and "Curcuma longa", "curcumin", "antioxidant effect", "anti-inflammatory effect" and "anti-cancer effect". C. longa and curcumin inhibited the production of the tumor necrosis factor-α (TNF-α) and prostaglandin E2 (PGE2) and increased the caspases (3, 8 and 9) activities in HL-60 prostate cancer. Furthermore, C. longa and curcumin suppressed the vascular endothelial growth factor (VEGF), phosphorylated signal transducers and activators of the transcription 3 (STAT) and matrix metalloproteinase-9 (MMP-9) in ovarian cancer cell line. C. longa and curcumin might decrease the risk of cancer and other malignant diseases in the reproductive system. C. longa and curcumin have a protective effect on the reproductive organs activity such as, anti-inflammatory, anti-apoptotic, and antioxidant effects in normal cells but showed pro-apoptotic effects in the malignant cells. Therefore, different effects of C. longa and curcumin are dependent on the doses and the type of cells used in various models studied.

    Turmeric (Curcuma longa), java turmeric (Curcuma xanthorrhiza) and cassumunar ginger (Zingiber cassumunar) are widely used in traditional Indonesian medicines (jamu). They have similar color for their rhizome and possess some similar uses, so it is possible to substitute one for the other. The identification and discrimination of these closely-related plants is a crucial task to ensure the quality of the raw materials. Therefore, an analytical method which is rapid, simple and accurate for discriminating these species using Fourier transform infrared spectroscopy (FTIR) combined with some chemometrics methods was developed. FTIR spectra were acquired in the mid-IR region (4000-400 cm(-1)). Standard normal variate, first and second order derivative spectra were compared for the spectral data. Principal component analysis (PCA) and canonical variate analysis (CVA) were used for the classification of the three species. Samples could be discriminated by visual analysis of the FTIR spectra by using their marker bands. Discrimination of the three species was also possible through the combination of the pre-processed FTIR spectra with PCA and CVA, in which CVA gave clearer discrimination. Subsequently, the developed method could be used for the identification and discrimination of the three closely-related plant species. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available The use of plant bioactives to replace antibiotics are now widely investigated. Turmeric or Curcuma longa (CL and curcuma xanthorrhiza (CX, are commonly used by human and known to have active ingredients as antimicrobial. Therefore a research was conducted to evaluate the possibility of using these plant bioactives to replace antibiotic in poultry feed. The bioactives concentration of the CL and CX powder were measured prior to the feeding trial and then supplemented into standard diets of broiler chikens. The levels tested in this trial were based on the active ingredients that could inhibit growth of bacteria and fungi, i.e., low, medium and high levels of the CL and CX, respectively. The combination of low level of CL + high level of CX and low level CL + medium level of CX were also tested. A diet without feed additives and with antibiotics were used as controls. Each diet was fed from day old to 35 days old, replicated 6 times and each replication consist of 15 birds. Results showed that neither the antibiotic tested nor the turmeric (CL, xanthorrhiza (CX nor the mixture of CL and CX gave significant (P>0.05 improvement on performances (body weight, FCR and mortatlity, nutrient digestibility of feed and carcass yield of broilers.

    Endophytes from medicinal plants represent a potential source of bioactive compounds. During the present investigation, fungal endophytes were isolated from turmeric (Curcuma longa), an important medicinal plant. A total of 207 endophytic fungal isolates were obtained from the rhizome of C. longa L. They were grouped into seven genera based on morphological and molecular data. The fungal endophytes of C. longa were evaluated for antifungal activity against Colletotrichum gloeosporioides, the causal organism of leaf spot of turmeric. The disease is a major cause for economic loss in turmeric cultivation. Endophytic Phoma herbarum showed significant activity against C. gloeosporioides and was therefore selected for further studies. A compound gentisyl alcohol was isolated from P. herbarum which showed effective antagonism against C. gloeosporioides. The organism could therefore be used as a biocontrol agent against C. gloeosporioides.

    Curcuma longa (C. longa) has been used as a spice in foods and as an antimicrobial in Oriental medicine. In this study, we evaluated the inhibitory effects of an essential oil isolated from C. longa on the cariogenic properties of Streptococcus mutans (S. mutans), which is an important bacterium in dental plaque and dental caries formation. First, the inhibitory effects of C. longa essential oil on the growth and acid production of S. mutans were tested. Next, the effect of C. longa essential oil on adhesion to saliva-coated hydroxyapatite beads (S-HAs) was investigated. C. longa essential oil inhibited the growth and acid production of S. mutans at concentrations from 0.5 to 4 mg/mL. The essential oil also exhibited significant inhibition of S. mutans adherence to S-HAs at concentrations higher than 0.5 mg/mL. S. mutans biofilm formation was determined by scanning electron microscopy (SEM) and safranin staining. The essential oil of C. longa inhibited the formation of S. mutans biofilms at concentrations higher than 0.5 mg/mL. The components of C. longa essential oil were then analyzed by GC and GC-MS, and the major components were α-turmerone (35.59%), germacrone (19.02%), α-zingiberene (8.74%), αr-turmerone (6.31%), trans-β-elemenone (5.65%), curlone (5.45%), and β-sesquiphellandrene (4.73%). These results suggest that C. longa may inhibit the cariogenic properties of S. mutans. © 2011 Institute of Food Technologists®

    Dengue is the most common infective disease caused by dengue virus (DENV) and endemic diseases in tropical and subtropical areas. Until now, there is no specific antiviral for dengue infection. It is known that viral load is related to disease severity. Curcuma longa L. (turmeric) with curcumin as major active compound has been identified for its antiviral effect. This study to determine antiviral effect of C. longa extract on DENV-2 in vitro and in vivo along with its toxicity in liver and kidney of ddY mice. Antiviral activity (IC50) and toxicity (CC50) in vitro was examined on Huh7it-1 cells by focus assay and a MTT assay, respectively. To determine the selectivity index (SI), we used CC50 and IC50 value. The safe doses obtained were used for toxicity tests of liver and kidney with histopathological and biochemical observations. The C. longa extracts was given orally with dose of 0.147 mg/mL for each mice at 2 hours after injected with DENV-2 infected Huh7it-1 cells. Serum was collected from intraorbital at 6 hours and 24 hours after infection and focus assay was used to determine viral load. In this study, the acquired value of IC50 was 17,91 μg/mL whereas the value of CC50 was 85,4 μg/mL. The value of SI of C. longa was 4.8. In vivo, we found that C. longa remarkable reduced of viral load after 24 hour. Histopathological examination showed no specific abnormalities in liver and kidney. There was no significant increase in levels of SGPT, SGOT, urea, and creatinine. From this study it can be concluded that C. longa could potentially be used as antiviral against DENV with low cytotoxicity and effective inhibition.

    The incidence of cancer is significantly lower in regions where turmeric is heavily consumed. Whether lower cancer incidence is due to turmeric was investigated by examining its effects on tumor cell proliferation, on pro-inflammatory transcription factors NF-κB and STAT3, and on associated gene products. Cell proliferation and cell cytotoxicity were measured by the MTT method, NF-κB activity by EMSA, protein expression by Western blot analysis, ROS generation by FACS analysis, and osteoclastogenesis by TRAP assay. Turmeric inhibited NF-κB activation and down-regulated NF-κB-regulated gene products linked to survival (Bcl-2, cFLIP, XIAP, and cIAP1), proliferation (cyclin D1 and c-Myc), and metastasis (CXCR4) of cancer cells. The spice suppressed the activation of STAT3, and induced the death receptors (DR)4 and DR5. Turmeric enhanced the production of ROS, and suppressed the growth of tumor cell lines. Furthermore, turmeric sensitized the tumor cells to chemotherapeutic agents capecitabine and taxol. Turmeric was found to be more potent than pure curcumin for cell growth inhibition. Turmeric also inhibited NF-κB activation induced by RANKL that correlated with the suppression of osteoclastogenesis. Our results indicate that turmeric can effectively block the proliferation of tumor cells through the suppression of NF-κB and STAT3 pathways. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.

    Herbal remedies are increasingly being recognised in recent years as alternative medicine for a number of diseases including cancer. Curcuma longa L., commonly known as turmeric is used as a culinary spice in India and in many Asian countries has been attributed to lower incidences of gastrointestinal cancers. Curcumin, a secondary metabolite isolated from the rhizomes of this plant has been shown to have significant anticancer properties, in addition to antimalarial and antioxidant effects. We sequenced the transcriptome of the rhizome of the 3 varieties of Curcuma longa L. using Illumina reversible dye terminator sequencing followed by de novo transcriptome assembly. Multiple databases were used to obtain a comprehensive annotation and the transcripts were functionally classified using GO, KOG and PlantCyc. Special emphasis was given for annotating the secondary metabolite pathways and terpenoid biosynthesis pathways. We report for the first time, the presence of transcripts related to biosynthetic pathways of several anti-cancer compounds like taxol, curcumin, and vinblastine in addition to anti-malarial compounds like artemisinin and acridone alkaloids, emphasizing turmeric's importance as a highly potent phytochemical. Our data not only provides molecular signatures for several terpenoids but also a comprehensive molecular resource for facilitating deeper insights into the transcriptome of C. longa. PMID:23468859

    Curcuminoids are pharmaceutically important compounds isolated from the herb Curcuma longa. Two additional type III polyketide synthases, named CURS2 and CURS3, that are capable of curcuminoid synthesis were identified and characterized. In vitro analysis revealed that CURS2 preferred feruloyl-CoA as a starter substrate and CURS3 preferred both feruloyl-CoA and p-coumaroyl-CoA. These results suggested that CURS2 synthesizes curcumin or demethoxycurcumin and CURS3 synthesizes curcumin, bisdemethoxycurcumin and demethoxycurcumin. The availability of the substrates and the expression levels of the three different enzymes capable of curcuminoid synthesis with different substrate specificities might influence the composition of curcuminoids in the turmeric and in different cultivars.

    Hydatid disease is an important economic and human public health problem with a wide geographical distribution. Surgical excision remains the primary treatment and the only hope for complete cure of hydatosis. The most important complications arising from surgical excision, however, is recurrence, which is due to dissemination of protoscolices during the surgery. Pre-surgical inactivation of the contents of the hydatid cyst by injection of scolicidal agent into the cyst has been used as adjunct to surgery in order to overcome the risk of recurrence. In the present study, ethanolic extracts of turmeric ( Curcuma longa ) and ginger ( Zingiber officinale ) were tested as scolicidal agent for Echinococcus protoscoleces. Protoscoleces were collected aseptically from sheep livers containing hydatid cysts. Three concentrations (10, 30 and 50 mg/ml) of each extract were investigated and viability of the protoscoleces was tested by 0.1% eosin staining. Ginger extract showed the strongest scolicidal effect (100%) after 20 min at a concentration of 30 mg/ml and 10 min at 50 mg/ml . The maximum scolicidal effect of turmeric was 93.2% after 30 min at a concentration of 50 mg/ml. It is concluded that turmeric and ginger extracts have high scolicidal activity and could be used as effective scolicidal agents against Echinococcus protoscoleces.

    Full Text Available ABSTRACT  Target production of catfish in aquaculture can be reached by suppressing the pathogenic bacterial infection. Previous works had shown that turmeric Curcuma longa has antibacterial activity. The objectives of this research were to determine the best method of extraction and to evaluate the efficacy of turmeric extract as feed additive to control Edwardsiella tarda disease in catfish culture. Briefly, the objective was achieved through in vitro assay based on inhibition ability of extraction method against E. tarda, while the following objective was obtained through in vivo assay based on their survival during challenge test either as preventive or curative measurement. A complete randomized design with three replications was used for each assay. Furthermore, challenge test was done by mean intraperitoneal injection at concentration 106 cfu/mL of E. tarda (LD50. The results showed that 15 minutes decoction method allowed the best inhibition with diameter 7.42 mm of clear zone and then curative measurement using turmeric extract could be the best application against E. tarda since it gave 86.67% of survival. Clinical signs such as swelling, hemoraghic, body ulcer, gastroentritis and gaseous captivity were observed on challenged fish. However, there were no significant different among treatments for specific growth, body weight, and absolute length parameters.  Keywords: Edwardsiella tarda, extraction, turmeric, catfish, inhibition zone  ABSTRAK Peningkatan produksi ikan lele dapat dicapai melalui pencegahan infeksi penyakit bakterial.

    To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl4 intoxicated Swiss albino mice. First group of mice (n=5) received CCl4 treatment at a dose of 0.5 mL/kg bw (i.p.) for 7 days. Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for 15 days. The third group was given both the turmeric extract (for 15 days, orally) and CCl4 (for last 7 days, i.p.). The fourth group was kept as a control. To study the liver function, the transaminase enzymes (SGOT and SGPT) and bilirubin level were measured in the serum of respective groups. For assaying the immunotherapeutic action of Curcuma longa (C. longa), non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups. The result of present study suggested that CCl4 administration increased the level of SGOT and SGPT and bilirubin level in serum. However, the aqueous extract of turmeric reduced the level of SGOT, SGPT and bilirubin in CCl4 intoxicated mice. Apart from damaging the liver system, CCl4 also reduced non specific host response parameters like morphological alteration, phagocytosis, nitric oxide release, myeloperoxidase release and intracellular killing capacity of peritoneal macrophages. Administration of aqueous extract of C. longa offered significant protection from these damaging actions of CCl4 on the non specific host response in the peritoneal macrophages of CCl4 intoxicated mice. In conclusion, the present study suggests that C. longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.

    Full Text Available Background: Treatment of plaque-induced periodontal disease is largely based on the mechanical debridement of the tooth surface and meticulous maintenance of oral hygiene thereafter. Various chemical plaque control agents are used as adjuncts along with the mechanical plaque control methods for this treatment. Most of these chemical plaque control agents have varied side effects. This has led to the search of natural products which are highly effective in controlling plaque microbes while being biocompatible. Turmeric is one such well-known plant product, known for its varied medicinal value. Aim: The aim of this study is to evaluate the clinical efficacy of Curcuma longa oral formulation in treatment of infective inflammatory early periodontal diseases. Materials and Methods: This clinical study comprised twenty individuals presenting with clinical features of plaque-induced gingivitis and mild periodontitis. Three groups were randomly made in mouth of each patient selected for the study. Group I was treated with scaling and root planing (SCRP only. Group II was treated with SCRP plus C. longa oral formulation topical application for 2 weeks. Group III was treated only with topical application of C. longa extract oral formulation for 2 weeks. Gingival index, sulcus bleeding index, and plaque index were scored in each group before and after the treatment. Results: The results showed statistically significant improvement with respect to all the clinical parameters in all the three groups. However, Group II showed the maximum improvement (P < 0.001, followed by Group I (P < 0.001 and Group III (P < 0.05. The intergroup difference between the three groups for the improvements in clinical parameters was statistically nonsignificant. Conclusion: The oral formulation containing C. longa extract is effective in treating early infective-inflammatory periodontal diseases not only when used as an adjunct to SCRP but also when used alone.

    Curcuma longa L. (turmeric) of ginger family (Zingiberaceae) belongs to the group of oldest cultivated spice plants in the south-east Asian countries. For many years rhizome of this plant has been used also as a safe and active drug for the treatment of various.chronic diseases, especially of diabetes mellitus (DM). The active substance of turmeric - curcumin (diferuloylmethane), possesses multiple therapeutic properties. In recent years, many detailed research (tests in vito and in vivo) along with clinical trials have revealed its very valuable biological activities related to its anti-inflammatory, antioxidant and cancer preventive properties, which are presented in numerous publications (1-6). At the molecular level it has been stated that curcumin inhibits cell proliferation, metastasis creation and apoptosis. Currently, great attention has been focused on curcumin as a blocker of TNF-s, which are the principal mediators of most inflammation-related disturbances (7). The main cause of blocking the broadly extended pharmacological and clinical investigations of curcumin is its extremely low solubility in water and in organ fluids. This feature consequently limits its systemic bioavailability and makes use of curcumin as a therapeutic remedy (to date) difficult. The primary aim of presently conducted research is to achieve increased solubilization and bioavailability of this promising nontoxic agent.

    Aflatoxins are highly toxic, mutagenic, teratogenic and carcinogenic mycotoxins. Consumption of aflatoxin-contaminated food and commodities poses serious hazards to the health of humans and animals. Turmeric, Curcuma longa L., is a native plant of Southeast Asia and has antimicrobial, antioxidant and antifungal properties. This paper reports the antiaflatoxigenic activities of the essential oil of C. longa and curcumin. The medium tests were prepared with the oil of C. longa, and the curcumin standard at concentrations varied from 0.01% to 5.0%. All doses of the essential oil of the plant and the curcumin standard interfered with mycotoxin production. Both the essential oil and curcumin significantly inhibited the production of aflatoxins; the 0.5% level had a greater than 96% inhibitory effect. The levels of aflatoxin B(1) (AFB(1)) production were 1.0 and 42.7 μg/mL, respectively, for the samples treated with the essential oil of C. longa L. and curcumin at a concentration of 0.5%.

    Green synthesis of noble metal nanoparticles is a vastly developing area of research. Metallic nanoparticles have received great attention from chemists, physicists, biologists, and engineers who wish to use them for the development of a new-generation of nanodevices. In this study, silver nanoparticles were biosynthesized from aqueous silver nitrate through a simple and eco-friendly route using Curcuma longa tuber-powder extracts, which acted as a reductant and stabilizer simultaneously. Characterizations of nanoparticles were done using different methods, which included ultraviolet-visible spectroscopy, powder X-ray diffraction, transmission electron microscopy, scanning electron microscopy, energy-dispersive X-ray fluorescence spectrometry, and Fourier-transform infrared spectroscopy. The ultraviolet-visible spectrum of the aqueous medium containing silver nanoparticles showed an absorption peak at around 415 nm. Transmission electron microscopy showed that mean diameter and standard deviation for the formation of silver nanoparticles was 6.30 ± 2.64 nm. Powder X-ray diffraction showed that the particles are crystalline in nature, with a face-centered cubic structure. The most needed outcome of this work will be the development of value-added products from C. longa for biomedical and nanotechnology-based industries. PMID:23341739

    2016-04-01

    Curcuma longa rhizome lectin, a mannose-binding protein of non-seed portions of turmeric, is known to have antifungal, antibacterial and α-glucosidase inhibitory activities. We studied the role of complex-type glycans attached to asparagine (Asn) 66 and Asn 110 to elucidate the role of carbohydrates in lectin activity and stability. Apart from the native lectin, the characteristics of a deglycosylated Escherichia coli expressed lectin, high-mannose oligosaccharides at both asparagines and its glycosylation mutants N66Q and N110Q expressed in Pichia pastoris, were compared to understand the relationship between glycosylation and activity. Far UV circular dichroism (CD) spectra, fluorescence emission maximum, hemagglutination assay show no change in secondary or tertiary structures or sugar-binding properties between wild-type and aforementioned recombinant lectins under physiological pH. But reduced agglutination activity and loss of tertiary structure are observed in the acidic pH range for the deglycosylated and the N110Q protein. In thermal and guanidine hydrochloride (GdnCl)-induced unfolding, the wild-type and high-mannose lectins possess higher stability compared with the deglycosylated recombinant lectin and both mutants, as measured by a higher Tm of denaturation or a greater free energy change, respectively. Reversibility experiments after thermal denaturation reveal that deglycosylated proteins tend to aggregate during thermal inactivation but the wild type shows a much greater recovery to the native state upon refolding. These results suggest that N-glycosylation in turmeric lectin is important for the maintenance of its proper folding upon changes in pH, and that the oligosaccharides help in maintaining the active conformation and prevent aggregation in unfolded or partially folded molecules. © The Author 2015.

    Urinary tract infection is caused primarily by the quorum sensing (QS)-dependent biofilm forming ability of uropathogens. In the present investigation, an anti-quorum sensing (anti-QS) agent curcumin from Curcuma longa (turmeric) was shown to inhibit the biofilm formation of uropathogens, such as Escherichia coli, Pseudomonas aeruginosa PAO1, Proteus mirabilis and Serratia marcescens, possibly by interfering with their QS systems. The antibiofilm potential of curcumin on uropathogens as well as its efficacy in disturbing the mature biofilms was examined under light microscope and confocal laser scanning microscope. The treatment with curcumin was also found to attenuate the QS-dependent factors, such as exopolysaccharide production, alginate production, swimming and swarming motility of uropathogens. Furthermore, it was documented that curcumin enhanced the susceptibility of a marker strain and uropathogens to conventional antibiotics. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Pterygium is a relatively common eye disease that can display an aggressive clinical behaviour. To evaluate the in vitro effects of Curcuma longa on human pterygium-derived keratinocytes, specimens of pterygium from 20 patients undergoing pterygium surgical excision were collected. Pterygium explants were put into culture and derived keratinocytes were treated with an alcoholic extract of 1.3% Curcuma longa in 0.001% Benzalkonium Chloride for 3, 6, and 24 h. Cultured cells were examined for CAM5.2 (anti-cytokeratin antibody) and CD140 (anti-fibroblast transmembrane glycoprotein antibody) expression between 3th and 16th passage to assess cell homogeneity. TUNEL technique and Annexin-V/PI staining in flow cytometry were used to detect keratinocyte apoptosis. We showed that Curcuma longa exerts a proapoptotic effect on pterygium-derived keratinocytes already after 3 h treatment. Moreover, after 24 h treatment, Curcuma longa induces a significant increase in TUNEL as well as Annexin-V/PI positive cells in comparison to untreated samples. Our study confirms previous observations highlighting the expression, in pterygium keratinocytes, of nuclear VEGF and gives evidence for the first time to the expression of nuclear and cytoplasmic VEGF-R1. All in all, these findings suggest that Curcuma longa could have some therapeutic potential in the treatment and prevention of human pterygium.

    Cerium chloride (CeCl 3 ) is considered an environmental pollutant and a potent neurotoxic agent. Medicinal plants have many bioactive compounds that provide protection against damage caused by such pollutants. Curcuma longa is a bioactive compound-rich plant with very important antioxidant properties. To study the preventive and healing effects of Curcuma longa on cerium-damaged mouse brains, we intraperitoneally injected cerium chloride (CeCl 3 , 20 mg/kg BW) along with Curcuma longa extract, administrated by gavage (100 mg/kg BW), into mice for 60 days. We then examined mouse behavior, brain tissue damage, and brain oxidative stress parameters. Our results revealed a significant modification in the behavior of the CeCl 3 -treated mice. In addition, CeCl 3 induced a significant increment in lipid peroxidation, carbonyl protein (PCO), and advanced oxidation protein product levels, as well as a significant reduction in superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities. Acetylcholinesterase (AChE) activity remarkably increased in the brain of CeCl 3 -treated mice. Histopathological observations confirmed these results. Curcuma longa attenuated CeCl 3 -induced oxidative stress and increased the activities of antioxidant enzymes. It also decreased AChE activity in the CeCl 3 -damaged mouse brain that was confirmed by histopathology. In conclusion, this study suggests that Curcuma longa has a neuroprotective effect against CeCl 3 -induced damage in the brain.

Cultured cells were examined for CAM5.2 (anti-cytokeratin antibody and CD140 (anti-fibroblast transmembrane glycoprotein antibody expression between 3th and 16th passage to assess cell homogeneity. TUNEL technique and Annexin-V/PI staining in flow cytometry were used to detect keratinocyte apoptosis. We showed that Curcuma longa exerts a proapoptotic effect on pterygium-derived keratinocytes already after 3 h treatment. Moreover, after 24 h treatment, Curcuma longa induces a significant increase in TUNEL as well as Annexin-V/PI positive cells in comparison to untreated samples. Our study confirms previous observations highlighting the expression, in pterygium keratinocytes, of nuclear VEGF and gives evidence for the first time to the expression of nuclear and cytoplasmic VEGF-R1. All in all, these findings suggest that Curcuma longa could have some therapeutic potential in the treatment and prevention of human pterygium.

    Full Text Available Solid lipid nanoparticles incorporating Curcuma longa L., Zingiberaceae, curcuminoids were produced by the hot melt emulsion method. A Box–Behnken factorial design was adopted to study the nanoparticles production at different levels of factors such as the percentage of curcuminoids, time of homogenization and surfactant ratio. The optimized nanoparticles were incorporated into hydrogels for stability, drug release and skin permeation tests. The average nanoparticle sizes were 210.4 nm; the zeta potential of −30.40 ± 4.16; the polydispersivity was 0.222 ± 0.125. The average encapsulation efficiency of curcumin and curcuminoids was 52.92 ± 5.41% and 48.39 ± 6.62%, respectively. Solid lipid nanocapsules were obtained with curcumin load varying from 14.2 to 33.6% and total curcuminoids load as high as 47.7%. The topical formulation containing SLN-Curcuminoids showed good spreadability and stability when subjected to mechanical stress test remained with characteristic color, showed no phase separation and no significant change in pH. As a result of slow release, the nanoparticles were able to avoid permeation or penetration in the pig ear epidermis/dermis during 18 h. The topical formulation is stable and can be used in further in vivo studies for the treatment of inflammatory reactions, in special for radiodermitis.

    Fourteen endophytic bacterial isolates were isolated from the rhizome of Curcuma longa L. were characterized on the basis of morphology, biochemical characteristics and 16S rRNA gene sequence analysis. The isolates were identified to six strains namely Bacillus cereus (ECL1), Bacillus thuringiensis (ECL2), Bacillus sp. (ECL3), Bacillus pumilis (ECL4), Pseudomonas putida (ECL5), and Clavibacter michiganensis (ECL6). All the strains produced IAA and solubilized phosphate and only two strains produced siderophore (ECL3 and ECL5) during plant growth promoting trait analysis. All the endophytic strains utilized glucose, sucrose and yeast extract as a carbon source where as glycine, alanine, cystine and glutamine as nitrogen source. The strains were mostly sensitive to antibiotic chloramphenicol followed by erythromycin while resistant to polymixin B. The endophytic strains effectively inhibit the growth of Escherichia coli, Klebsiella pneumoniae and some of the fungal strain like Fusarium solani and Alterneria alternata. The strain ECL2 and ECL4 tolerated maximum 8 % of NaCl concentration where as strains ECL5 and ECL6 6 % in salinity tolerance.

    An integral type natural convection solar drier has been fabricated and coupled with a biomass stove. Experiments have been conducted to test the performance of the drier by drying of Zingiber officinale (ginger), Curcuma longa l. (turmeric) and Tinospora cordifolia (guduchi) during the summer climate in Delhi. It was found that, during the load test for ginger, 18 kg of fresh product with an initial moisture content of 319.74(db)% was dried to a final moisture content of 11.8(db)% within 33 h. Similarly, moisture content of turmeric and guduchi were reduced from 358.96 to 8.8 and 257.45 to 9.67(db)% during 36 and 48 h of drying, respectively. The drying of these products has also been studied under 'solar-only' and open sun in the same climatic conditions and the results indicate that for all the products, drying is faster, and is within 33-48 h in hybrid drier, against 72-120 h in 'solar-only' operation of the same drier and 192-288 h in open sun. Efficiency of the drier during its two mode (solar and biomass separately) of operation has been estimated and quality evaluation of under-studied products showed that developed drier is suitable for the drying of these products. The developed drier is a simple system, which can be manufactured locally and can be used for drying of other agricultural products. (author)

    The present study is aimed at evaluating the protective effects of oils from Zingiber officinale (ginger) and Curcuma longa (turmeric) on acute ethanol-induced fatty liver in male Wistar rats. Ferric reducing antioxidant power activity and oxygen radical absorbance capacity of the oils were evaluated ex vivo. Rats were pretreated for 28 d with standard drug (Livolin Forte) and oils from Z. officinale and C. longa before they were exposed to 45% ethanol (4.8 g/kg) to induce acute fatty liver. Histological changes were observed and the degree of protection was measured by using biochemical parameters such as alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activities. Serum triglyceride (TG) level, total cholesterol (TC) level and the effects of both oils on reduced gluthatione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD) and hepatic malondialdehyde (MDA) levels were estimated. Oils from Z. officinale and C. longa at a dose of 200 mg/kg showed hepatoprotection by decreasing the activities of serum enzymes, serum TG, serum TC and hepatic MDA, while they significantly restored the level of GSH as well as GST and SOD activities. Histological examination of rats tissues was related to the obtained results. From the results it may be concluded that oils from Z. officinale and C. longa (200 mg/kg) exhibited hepatoprotective activity in acute ethanol-induced fatty liver and Z. officinale oil was identified to have better effects than C. longa oil.

Other animals fed daily on high fat diets containing either raw or irradiated turmeric powder (2 g per 100 g diet) at doses 10, 15 or 20 kGy for 6 weeks. The results showed that the relative spleen, kidneys, heart, lungs, and testes weight, and the levels of Hb, PCV and MCHC were not changed in animals fed the experimental diets for 6 weeks. Animals kept on HFD suffered from liver enlargement. Dietary interventions through administrating 2% (w/w) raw or irradiated turmeric powder at 20 kGy normalized the liver size as compared with those received reference diet. Meanwhile, the results revealed that rats fed on high fat diet significantly increased plasma AST, ALT, TC and TG and significant decrease was observed in HDL. Meanwhile, feeding rats on diet containing of either raw or irradiated turmeric powder at 10, 15 and 20 kGy induced a significant improvement in the above mentioned parameters. These results imply that irradiated turmeric powder at 20 kGy can offer protection against the biochemical changes as a consequence of hyperlipidaemic food and contribute to the regulation of lipid metabolism safely

    Curcuma longa is a plant that belongs to the ginger family, Zingiberaceae. It has been used in Siddha medicine for thousands of years in Asia. Parkinson's disease (PD) is a degenerative disorder of the central nervous system that affects the motor system of the brain. Death of dopamine-producing cells in the substantia nigra leads to PD. Exposure to salsolinol, which is an endogenous neurotoxin, has been associated with damage to dopamine-producing cells. The present study assessed the toxicity of salsolinol in SH-SY5Y human neuroblastoma cells and subsequently investigated the neuroprotective potential of C. longa extract in salsolinol-induced toxic conditions in SH-SY5Y cells. Sulphorhodamine-B assay showed the protective effect of the anti-apoptotic effect of treated SH-SY5Y cells. Fluorescence microscopy and confocal laser scanning microscope analysis indicated the anti-apoptotic impact of the C. longa extract. Mitochondria-derived reactive oxygen species were reduced in C. longa extract-treated SH-SY5Y cells. Downregulated mRNA expression levels of p53, Bcl-2-associated X protein and caspase 3 were observed in the C. longa extract-treated SH-SY5Y cells. Caspase 3 activity was reduced in the C. longa extract-treated SH-SY5Y cells. In conclusion, the present findings demonstrated that solsolinol is neurotoxic to SH-SY5Y cells, and C. longa extract may be useful in the treatment of PD.

    Curcuma longa possesses powerful antifungal activity, as demonstrated in many studies. In this study, the antifungal spectrum of Curcuma longa alcohol extract was determined, and the resulting EC50 values (mg/mL) of its extract on eleven fungi, including Fusarium graminearum, Fusarium chlamydosporum, Alternaria alternate, Fusarium tricinctum, Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium culmorum, Rhizopus oryzae, Cladosporium cladosporioides, Fusarium oxysporum and Colletotrichum higginsianum, were 0.1088, 0.1742, 0.1888, 0.2547, 0.3135, 0.3825, 0.4229, 1.2086, 4.5176, 3.8833 and 5.0183, respectively. Among them, F. graminearum was selected to determine the inhibitory effects of the compounds (including curdione, isocurcumenol, curcumenol, curzerene, β-elemene, curcumin, germacrone and curcumol) derived from Curcuma longa. In addition, the antifungal activities of curdione, curcumenol, curzerene, curcumol and isocurcumenol and the synergies of the complexes of curdione and seven other chemicals were investigated. Differential proteomics of F. graminearum was also compared, and at least 2021 reproducible protein spots were identified. Among these spots, 46 were classified as differentially expressed proteins, and these proteins are involved in energy metabolism, tRNA synthesis and glucose metabolism. Furthermore, several fungal physiological differences were also analysed. The antifungal effect included fungal cell membrane disruption and inhibition of ergosterol synthesis, respiration, succinate dehydrogenase (SDH) and NADH oxidase. PMID:29543859

    The effects of dietary supplementation with an organic extract of Curcuma longa on systemic and local immune responses to experimental Eimeria maxima and Eimeria tenella infections were evaluated in commercial broiler chickens. Dietary supplementation with C. longa enhanced coccidiosis resistance as demonstrated by increased BW gains, reduced fecal oocyst shedding, and decreased gut lesions compared with infected birds fed a nonsupplemented control diet. The chickens fed C. longa-supplemented diet showed enhanced systemic humoral immunity, as assessed by greater levels of serum antibodies to an Eimeria microneme protein, MIC2, and enhanced cellular immunity, as measured by concanavalin A-induced spleen cell proliferation, compared with controls. At the intestinal level, genome-wide gene expression profiling by microarray hybridization identified 601 differentially expressed transcripts (287 upregulated, 314 downregulated) in gut lymphocytes of C. longa-fed chickens compared with nonsupplemented controls. Based on the known functions of the corresponding mammalian genes, the C. longa-induced intestinal transcriptome was mostly associated with genes mediating anti-inflammatory effects. Taken together, these results suggest that dietary C. longa could be used to attenuate Eimeria-induced, inflammation-mediated gut damage in commercial poultry production.

    Diabetes mellitus is an important human disease afflicting many from various walks of life in different countries. Even though modern medicines contribute a variety of effective treatment options, they can have several unfavourable effects. The intention of this review is to organize and discuss various studies that have been previously conducted on the effectiveness of these herbal plants in diabetes. By using various electronic search databases, a comprehensive English literature search was conducted. Different search terms were used by combining all the search fields in titles, abstracts and keywords. Curcuma longa, a spice, is commonly known as turmeric and belongs to the family Zingiberaceae. Piper nigrum is also a spice, commonly called black pepper, and belongs to the family Piperaceae. Phoenix dactylifera , commonly known as date fruit, belongs to the family Arecaceae. From ancient times, they have been traditionally used for the treatment of various diseases. Among various activities, regulation of hyperglycaemia is considered one of their important effects. One of the aetiological factors implicated in the development of diabetes and its complications is the damage induced by free radicals. Antioxidant properties of antidiabetic compounds would be more beneficial. Extracts of these plants have shown hypoglycaemic and hypolipidaemic effects by the involvement of several mechanisms. In the future, further studies are needed to investigate the mechanisms involved in their hypoglycaemic potential and their active constituents as synthetic analogues. This review focusses on some medicinal plants that have antidiabetic effect, thus contributing to the reduction of risk factors associated with diabetes, and related beneficial effects are compiled.

    Curcumin, a biphenolic compound extracted from turmeric (Curcuma longa), possesses potent anti-inflammatory activity. The present study investigated whether curcumin could increase 5' adenosine monophosphate-activated protein kinase (AMPK) activity in macrophages and modulate the severity of lipopolysaccharide (LPS)-induced acute lung injury. Macrophages were treated with curcumin and then exposed (or not) to LPS. Acute lung injury was induced by intratracheal administration of LPS in BALB/c mice. Curcumin increased phosphorylation of AMPK and acetyl-CoA carboxylase (ACC), a downstream target of AMPK, in a time- and concentration-dependent manner. Curcumin did not increase phosphorylation of liver kinase B1, a primary kinase upstream of AMPK. STO-609, an inhibitor of calcium(2+)/calmodulin-dependent protein kinase kinase, diminished curcumin-induced AMPK phosphorylation, but transforming growth factor-beta-activated kinase 1 inhibitor did not. Curcumin also diminished the LPS-induced increase in phosphorylation of inhibitory κB-alpha and the production of tumor necrosis factor alpha (TNF-α), macrophage inflammatory protein (MIP)-2, and interleukin (IL)-6 by macrophages. Systemic administration of curcumin significantly decreased the production of TNF-α, MIP-2, and IL-6 as well as neutrophil accumulation in bronchoalveolar lavage fluid, and also decreased pulmonary myeloperoxidase levels and the wet/dry weight ratio in mice subjected to LPS treatment. These results suggest that the protective effect of curcumin on LPS-induced acute lung injury is associated with AMPK activation.

    AIM The rhizome of turmeric, Curcuma longa (CL), is a herbal medicine used in many traditional prescriptions. It has previously been shown that CL treatment showed greater than 47% recovery from cisplatin-induced cell damage in human kidney HEK 293 cells. This study was conducted to evaluate the recovery mechanisms of CL that occur during cisplatin induced nephrotoxicity by examining the genome wide mRNA expression profiles of HEK 293 -cells. METHOD Recovery mechanisms of CL that occur during cisplatin-induced nephrotoxicity were determined by microarray, real-time PCR, immunofluorescent confocal microscopy and Western blot analysis. RESULTS The results of microarray analysis and real-time PCR revealed that NFκB pathway-related genes and apoptosis-related genes were down-regulated in CL-treated HEK 293 cells. In addition, immunofluorescent confocal microscopy and Western blot analysis revealed that NFκB p65 nuclear translocation was inhibited in CL-treated HEK 293 cells. Therefore, the mechanism responsible for the effects of CL on HEK 293 cells is closely associated with regulation of the NFκB pathway. CONCLUSION CL possesses novel therapeutic agents that can be used for the prevention or treatment of cisplatin-induced renal disorders. PMID:20840446

    Dietary spice components ofCurcuma longa andAbroma augusta have been screened for their protective effect against reactive oxygen species induced lipid peroxidation. They have been found to be efficient antioxidant when administered in combination. The purpose of the study was to investigate the effect of oral administration (300mg/Kg) of the aqueous extract of turmeric whose active ingredient isCurcumin andAbromine powder as a hypoglycemic agent mixed with diet. The effect of this aqueous extract on blood glucose, lipid peroxidation (LPO) and the antioxidant defense system in rat tissues like liver, lung, kidney and brain was studied for 8 weeks in streptozotocin induced diabetic rats. The administration of an aqueous extract of turmeric and abromine powder resulted in a significant reduction in blood glucose and an increase in total haemoglobin. The aqueous extract also resulted in decreased free radical formation in the tissues studied.The decrease in thiobarbituric acid reactive substances (TBARS) and increase in reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) clearly showed the antioxidant property of the mixture. It is suggested that these changes initially counteract the oxidative stress in diabetes however, a gradual decrease in the antioxidative process may be one of the factors which results in chronic diabetes. These results indicate that the mixture of the two plants have shown antidiabetic activity and also reduced oxidative stress in diabetes. A combination ofAbroma augusta and Curcuma longa also restored the other general parameters in diabetic animals. The results were statistically analyzed and indicated that combination of herbal extracts showed better efficacy as compared to individual herbal plant extracts used.

    Turmeric or Curcuma is a natural product that has anti-inflammatory, antioxidant and anti-apoptotic pharmacological properties. It can be used in the control of the aging process that involves oxidative stress, inflammation, and apoptosis. Aging is a physiological process that affects higher cortical and cognitive functions with a reduction in learning and memory, limited judgment and deficits in emotional control and social behavior. Moreover, aging is a major risk factor for the appearance of several disorders such as cerebrovascular disease, diabetes mellitus, and hypertension. At the brain level, the aging process alters the synaptic intercommunication by a reduction in the dendritic arbor as well as the number of the dendritic spine in the pyramidal neurons of the prefrontal cortex, hippocampus and basolateral amygdala, consequently reducing the size of these regions. The present review discusses the synaptic changes caused by the aging process and the neuroprotective role the Curcuma has through its anti-inflammatory, antioxidant and anti-apoptotic actions.

    Streptococcus biofilm on tooth surfaces can decrease mouth environment pH, thus causing enamel demineralization that can lead to dental caries. Java Turmeric extract has excellent antibacterial effects and can maintain S. mutans biofilm pH at neutral levels for 4 hours. To analyze the effect of Java Turmeric extract on tooth enamel micro-hardness, the Java Turmeric extract was added on enamel tooth samples with Streptococcus dual species biofilm (S. sanguinis and S. mutans). The micro-hardness of enamel was measured by Knoop Hardness Tester. Results showed that Curcuma xanthorrhiza Roxb. could not maintain tooth enamel surface micro-hardness. It is concluded that Java Turmeric extract ethanol could not inhibit the hardness of enamel with Streptococcus dual species biofilm.

    Food irradiation is a technology to control spoilage and eliminate food-borne pathogens such as Escherichia coli, salmonella, yeasts and mold. It is also applied to spices, herbs, and natural products including Fahthalai and Curcuma longa (C. longa) products. Therefore, it is important to study the effect of irradiation on the active compounds in these products (two crude and two extracts). The results indicated that HPLC and TLC fingerprints of C. longa samples were similar for both before and after irradiation (2.5, 5, 10, 25 kGy). There were no any new compounds occurred after irradiation and during storage. The curcumin content in C. longa crude (2 samples) was stable during 12 months of this study. However, the curcumin content in 2 extracts trended to increase during storage time. Irradiation process at least 5 kGy can reduce some bacteria and fungi contaminations in natural products to the acceptable level indicated in the quality control methods for medicinal plant materials (WHO, 1998). The amount of microorganism growth were not more than 105, 104, 103 colony forming unit (CFU) of each sample for aerobic bacteria, fungi, and enterobacteriaceae growth, respectively, and E. coli, Salmonella spp. and Staphylococcus aureus were not found in all samples

    Curcuma longa L., belonging to the Zingiberaceae family, is a perennial herb and has been used as a spice and a pigment in the food industry. In the ongoing search for inhibitory reagents of NO production and survey of the chemical composition of natural vegetable foods, the chemical constituents of C. longa used as spice were investigated. This investigation resulted in the isolation of 2 new terpenoids and 14 known analogues. Their structures were established on the basis of the extensive analyses of 1D and 2D NMR spectroscopic data, and the absolute configurations of 1-4 were elucidated by comparison of the calculated and experimental ECD spectra. Among them, compound 1 is a rare norditerpene with an ent-labdane skeleton, and 2 is a skeletally novel sesquiterpene having an eight-membered ring. All of the compounds were found to possess NO inhibitory activities in murine microglial BV-2 cells. The discovery of two new compounds in this chemical investigation further disclosed the chemical composition of C. longa used a food spice, and the bioassay implied that the natural food spice C. longa, containing terpenoids with NO inhibitory activities, may be potentially promotive to human health.

    Curcuma longa (C. longa) is commonly found in different areas of Pakistan. It has been locally utilized as a traditional medicine. The aim of this study was to evaluate the antidiabetic, hepatoprotective and total antioxidant effect of the crude drug and its methanolic extract in rabbits. Diabetes was induced with alloxan (180mg/kg). Two major groups were designed, curative and protective groups. In curative group the crude drug and its methanolic extract was orally administered to the diabetic animals and acute study was performed. On the other hand in protective group the crude drug and its methanolic extract were administered for eight days prior to the diabetes induction. Results indicated that in Curative group the crude and methanolic extract of C. longa significantly improved the levels of serum glucose, serum transaminases and antioxidant activity (AOA). In protective group, serum glucose, serum transaminases were not significantly increased by alloxan, in both crude as well as methanolic extract group. This study shows that C. longa acts as antidiabetic, hepatoprotective and antioxidant in diabetes especially type 1 diabetes.

    Full Text Available Supra-nutritional doses of curcumin, derived from the spice Curcuma longa, have been proposed as a potential treatment of inflammation and metabolic disorders related to obesity. The aim of the present study was to test whether Curcuma longa extract rich in curcumin and associated with white pepper (Curcuma-P®, at doses compatible with human use, could modulate systemic inflammation in diet-induced obese mice. We questioned the potential relevance of changes in adiposity and gut microbiota in the effect of Curcuma-P® in obesity.Mice were fed either a control diet (CT, a high fat (HF diet or a HF diet containing Curcuma longa extract (0.1 % of curcumin in the HF diet associated with white pepper (0.01 % for four weeks. Curcumin has been usually combined with white pepper, which contain piperine, in order to improve its bioavailability. This combination did not significantly modify body weight gain, glycemia, insulinemia, serum lipids and intestinal inflammatory markers. Tetrahydrocurcumin, but not curcumin accumulated in the subcutaneous adipose tissue. Importantly, the co-supplementation in curcuma extract and white pepper decreased HF-induced pro-inflammatory cytokines expression in the subcutaneous adipose tissue, an effect independent of adiposity, immune cells recruitment, angiogenesis, or modulation of gut bacteria controlling inflammation.These findings support that nutritional doses of Curcuma longa, associated with white pepper, is able to decrease inflammatory cytokines expression in the adipose tissue and this effect could be rather linked to a direct effect of bioactive metabolites reaching the adipose tissue, than from changes in the gut microbiota composition.

    Curzerene is a sesquiterpene and component used in oriental medicine. It was originally isolated from the traditional Chinese herbal medicine Curcuma rhizomes. In this study, anticancer activity of curzerene was examined in both in vitro and in vivo models. The result of the MTT assay showed that curzerene exhibited antiproliferative effects in SPC-A1 human lung adenocarcinoma cells in a time-dependent and dose-dependent manner. The anticancer IC 50 s were 403.8, 154.8, and 47.0 µM for 24, 48, and 72 hours, respectively. The flow cytometry analysis indicated curzerene arrested the cells in the G2/M cell cycle and promoted or induced apoptosis of SPC-A1 cells. The percentage of cells arrested in the G2/M phase increased from 9.26 % in the control group cells to 17.57 % in the cells treated with the highest dose (100 µM) of curzerene. Western blot and RT-PCR analysis demonstrated that curzerene induced the downregulation of GSTA1 protein and mRNA expressions in SPC-A1 cells. Tumor growth was significantly inhibited in SPC-A1 cell-bearing nude mice by using curzerene (135 mg/kg daily), meanwhile, curzerene did not significantly affect body mass and the organs of the mice, which may indicate that curzerene has limited toxicity and side effects in vivo . In conclusion, curzerene could inhibit the proliferation of SPC-A1 human lung adenocarcinoma cells line in both in vitro and in vivo models. Focusing on its relationship with GSTA1, curzerene could induce the downregulation of GSTA1 protein and mRNA expressions in SPC-A1 cells. Curzerene might be used as an anti-lung adenocarcinoma drug candidate compound for further development. Georg Thieme Verlag KG Stuttgart · New York.

    Curcuma longa L. is an important industrial crop used by medicinal and cosmetic industries in the world. Its leaves are a waste material after harvesting rhizomes. The aim of the study was to evaluate the chemical and pharmacological profile of essential oil from waste leaves of Curcuma longa (EOCl) against skin inflammation. EOCl was subjected to gas chromatography (GC) analysis for identification of essential oil constituents and its anti-inflammatory evaluation through in vitro and in vivo models. Chemical fingerprinting using GC and GC-MS analysis of EOCl revealed the presence of 11 compounds, representing 90.29% of the oil, in which terpinolene (52.88%) and α-phellandrene (21.13%) are the major components. In the in vitro testing EOCl inhibited the production of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) in lipopolysaccharide (LPS) and 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in the human keratinocyte cell line (HaCaT). Topical application of EOCl produced anti-inflammatory effects by reducing ear thickness, ear weight and ameliorating the level of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) at protein and mRNA levels as well as regulating the overproduction of oxidative markers and restoring the histopathological damage in a TPA-induced mouse model of inflammation. These findings of topical anti-inflammatory properties of EOCl provide a scientific basis for medicinal use of this plant material against inflammatory disorders.

    Nanomaterials based fluorescent agents are rapidly becoming significant and promising transformative tools for improving medical diagnostics for extensive in vivo imaging modalities. Compared with conventional fluorescent agents, nano-fluorescence has capabilities to improve the in vivo detection and enriched targeting efficiencies. In our laboratory we synthesized fluorescent metal nanoparticles of silver, copper and iron using Curcuma longa tuber powder by simple reduction. The physicochemical properties of the synthesized metal nanoparticles were attained using UV-visible spectrophotometry, scanning electron microscopy with EDAX spectroscopy, dynamic light scattering, Fourier-transform infrared spectroscopy and X-ray diffraction. The Curcuma longa tuber powder has one of the bioactive compound Curcumin might act as a capping agent during the synthesis of nanoparticles. The synthesized metal nanoparticles fluorescence property was confirmed by spectrofluorometry. When compared with copper and iron nanoparticles the silver nanoparticles showed high fluorescence intensity under spectrofluorometry. Moreover, in vitro cell images of the silver nanoparticles in A549 cell lines also correlated with the results of spectrofluorometry. These silver nanoparticles show inspiring cell-imaging applications. They enter into cells without any further modifications, and the fluorescence property can be utilized for fluorescence-based cell imaging applications.

    To establish a new method for the extraction and separation of curcuminoids from Curcuma longa rhizome by cloud-point preconcentration using microemulsions as solvent. The spectrophotometry was used to detect the solubility of curcumin in different oil phase, emulsifier and auxiliary emulsifier, and the microemulsion prescription was used for false three-phase figure optimization. The extraction process was optimized by uniform experiment design. The curcuminoids were separated from microemulsion extract by cloud-point preconcentration. Oil phase was oleic acid ethyl ester; Emulsifier was OP emulsifier; Auxiliary emulsifier was polyethylene glycol(peg) 400; The quantity of emulsifier to auxiliary emulsifier was the ratio of 5: 1; Microemulsion prescription was water-oleic acid ethyl ester-mixed emulsifier (0.45:0.1:0.45). The optimum extraction process was: time for 12.5 min, temperature of 52 degrees C, power of 360 W, frequency of 400 kHz, and the liquid-solid ratio of 40:1. The extraction rate of curcuminoids was 92.17% and 86.85% in microemulsion and oil phase, respectively. Curcuminoids is soluble in this microemulsion prescription with good extraction rate. This method is simple and suitable for curcuminoids extraction from Curcuma longa rhizome.

    The aim of the study was to investigate the safety and anti-inflammatory effects of polysaccharide fraction (F1) of Curcuma longa extract (NR-INF-02) in classical rodent models of inflammation. F1 was evaluated for its acute oral toxicity and found to be safe upto 5000 mg/kg body weight in rats. The anti-inflammatory activity of F1 was evaluated in acute (carrageenan - induced paw edema; xylene - induced ear edema) and chronic (cotton pellet - induced granuloma) models of inflammation. The results of the study demonstrated that F1 significantly (p ≤ 0.05) inhibited carrageenan-induced paw edema at 1 h and 3 h at doses of 11.25, 22.5 and 45 mg/kg body weight in rats. Also, F1 at doses of 15.75, 31.5 and 63 mg/kg significantly inhibited the xylene induced ear edema in mice. In a chronic model, F1 at 11.25, 22.5 and 45 mg/kg doses produced significant reduction of wet and dry weights of cotton pellets in rats. Overall results indicated that F1 of NR-INF-02 significantly attenuated acute and chronic inflammation in rodent models. This study emphasizes on the importance of Curcuma longa polysaccharide's role in acute and chronic inflammation.

    Turmeric is a rich source of bioactive compounds useful in both medicine and cuisine. Mineral concentrations effects (PO 4 3- , Ca 2+ , Mg 2+ , and KNO 3 ) were tested during in vitro rhizome development on the ex vitro content of volatile constituents in rhizomes after 6 months in the greenhouse. A response surface method (D-optimal criteria) was repeated in both high and low-input fertilizer treatments. Control plants were grown on Murashige and Skoog (MS) medium, acclimatized in the greenhouse and grown in the field. The volatile constituents were investigated by GC-MS. The total content of volatiles was affected by fertilizer treatments, and in vitro treatment with Ca 2+ and KNO 3 ; but PO 4 3- and Mg 2+ had no significant effect. The content was higher in the high-input fertilizer treatments (49.7 ± 9 mg/g DM) with 4 mM Ca 2+ , 60 mM KNO 3 and 5 mM NH 4 + , than the low-input fertilizer (26.6 ± 9 mg/g DM), and the MS control (15.28 ± 2.7 mg/g DM; 3 mM Ca 2+ , 20 mM K + , 39 mM NO 3 - , 20 mM NH 4 + , 1.25 mM PO 4 3- , and 1.5 mM Mg 2+ ). The interaction of Ca 2+ with KNO 3 affected curcumenol isomer I and II, germacrone, isocurcumenol, and β-elemenone content. Increasing in vitro phosphate concentration to 6.25 mM increased ex vitro neocurdione and methenolone contents. These results show that minerals in the in vitro bioreactor medium during rhizome development affected biosynthesis of turmeric volatile components after transfer to the greenhouse six months later. The multi-factor design identified 1) nutrient regulation of specific components within unique phytochemical profile for Curcuma longa L. clone 35-1 and 2) the varied phytochemical profiles were maintained with integrity during the greenhouse growth in high fertility conditions.

    Antioxidant, anticholinesterase and antidiabetic activities of three curcuminoids isolated from the Curcuma longa were simultaneously tested and compared in this study. The highest antioxidant power was detected for curcumin with the applied methods. The drug potentials of curcuminoids for Alzheimer's disease were controlled. Bisdemethoxycurcumin (BDMC) showed substantial inhibitory activity. The activity of demethoxycurcumin (DMC) followed BDMC, whereas curcumin showed very little acetylcholinesterase inhibition activity. Antidiabetic activity of curcuminoids was evaluated by their α-glucosidase inhibitory activities. All curcuminoids show activities with decreasing order as BDMC > curcumin > DMC. The significant activities of BDMC compared to its isomers and examination of chemical structures of isomers might be a starting point in designing new drugs for Alzheimer's and Diabetes Mellitus.

    Naked maghemite nanoparticles, namely, surface active maghemite nanoparticles (SAMNs), characterized by a diameter of about 10 nm, possessing peculiar colloidal stability, surface chemistry, and superparamagnetism, present fundamental requisites for the development of effective magnetic purification processes for biomolecules in complex matrices. Polyphenolic molecules presenting functionalities with different proclivities toward iron chelation were studied as probes for testing SAMN suitability for magnetic purification. Thus, the binding efficiency and reversibility on SAMNs of phenolic compounds of interest in the pharmaceutical and food industries, namely, catechin, tyrosine, hydroxytyrosine, ferulic acid, coumaric acid, rosmarinic acid, naringenin, curcumin, and cyanidin-3-glucoside, were evaluated. Curcumin emerged as an elective compound, suitable for magnetic purification by SAMNs from complex matrices. A combination of curcumin, demethoxycurcumin, and bis-demethoxycurcumin was recovered by a single magnetic purification step from extracts of Curcuma longa rhizomes, with a purity >98% and a purification yield of 45%, curcumin being >80% of the total purified curcuminoids.

    Full Text Available Turmeric or Curcuma is a natural product that has anti-inflammatory, antioxidant and anti-apoptotic pharmacological properties. It can be used in the control of the aging process that involves oxidative stress, inflammation, and apoptosis. Aging is a physiological process that affects higher cortical and cognitive functions with a reduction in learning and memory, limited judgment and deficits in emotional control and social behavior. Moreover, aging is a major risk factor for the appearance of several disorders such as cerebrovascular disease, diabetes mellitus, and hypertension. At the brain level, the aging process alters the synaptic intercommunication by a reduction in the dendritic arbor as well as the number of the dendritic spine in the pyramidal neurons of the prefrontal cortex, hippocampus and basolateral amygdala, consequently reducing the size of these regions. The present review discusses the synaptic changes caused by the aging process and the neuroprotective role the Curcuma has through its anti-inflammatory, antioxidant and anti-apoptotic actions

Moreover, aging is a major risk factor for the appearance of several disorders such as cerebrovascular disease, diabetes mellitus, and hypertension. At the brain level, the aging process alters the synaptic intercommunication by a reduction in the dendritic arbor as well as the number of the dendritic spine in the pyramidal neurons of the prefrontal cortex, hippocampus and basolateral amygdala, consequently reducing the size of these regions. The present review discusses the synaptic changes caused by the aging process and the neuroprotective role the Curcuma has through its anti-inflammatory, antioxidant and anti-apoptotic actions PMID:28761413

    Curcuma caesia Roxb. (Black turmeric), a perennial herb of the family Zingiberaceae is indigenous to India. C. caesia is used as a spice, food preservative and coloring agent commonly in the Indian subcontinent. Functional parametric pharmacological evaluations like drug ability and toxicity profile of this endangered species is poorly documented. In our present study, among all the extracts of dried C. caesia rhizome viz- hexane, ethyl acetate, methanol and water tested for free radical scavenging capacity by total antioxidant activity (TAO) method, Hexane Rhizome Extract (HRE) was found to possess remarkable activity (1200mg ascorbic acid equivalent/100g). In MTT assay across three cancer cell lines and a control cell line, HRE exhibited a dose-dependent inhibition only in cancer cells, with notable activity in HepG2 cell lines (IC50: 0976µg/mL). Further, western blotting and flow cytometry experiments proved that HRE induces cell arrest at G2/M phase along with cellular apoptosis as suggestive by multiple-point mitochondrial mediated intrinsic pathway of Programmed Cell Death (PCD). Gas Chromatography-Mass Spectrophotometry (GC-MS) analysis of HRE suggested twenty compounds that when docked in silico with Tubulin (1SA0) and Epidermal Growth Factor Receptor/ EGFR (1XKK) showed very intimate binding with the original ligands. Our results provided significant evidence of the toxicity mechanisms of HRE that may be beneficial for more rational applications of drug discovery for slowing down cancer progression.

    Full Text Available Intake of food and nutrition plays a major role in affecting aging process and longevity. However, the precise mechanisms underlying the ageing process are still unclear. To this respect, diet has been considered to be a determinant of ageing process. In order to better illustrate this, we used Drosophila melanogaster as a model and fed them orally with different concentrations of two commonly used Indian medicinal plant products, Curcuma longa (rhizome and Emblica officinalis (fruit. The results revealed significant increase in life span of Drosophila flies on exposure to both the plant products, more efficiently by C. Longa than by E. officinalis. In order to understand whether the increase in lifespan was due to high-antioxidant properties of these medicinal plants, we performed enzymatic assays to assess the SOD and catalase activities in case of both treated and control Drosophila flies. Interestingly, the results support the free radical theory of aging as both these plant derivatives show high reactive oxygen species (ROS scavenging activities.

    Mosquito repellents play an important role in preventing man-mosquito contact. In the present study, we evaluated the synergistic mosquito-repellent activity of Curcuma longa, Pogostemon heyneanus and Zanthoxylum limonella essential oils. The mosquito repellent efficacies of three essential oils were evaluated separately and in combination under laboratory and field conditions. N,N-Diethylphenylacetamide (DEPA) and dimethylphthalate (DMP) were used for comparison of the protection time of the mixture of essential oils. At an optimum concentration of 20%, the essential oils of C. longa, Z. limonella and P. heyneanus provided complete protection times (CPTs) of 96.2, 91.4 and 123.4 min, respectively, against Aedes albopictus mosquitoes in the laboratory. The 1:1:2 mixture of the essential oils provided 329.4 and 391.0 min of CPT in the laboratory and field trials, respectively. The percent increases in CPTs for the essential oil mixture were 30 for DMP and 55 for N,N-diethylphenylacetamide (DEPA). The synergistic repellent activity of the essential oils used in the present study might be useful for developing safer alternatives to synthetic repellents for personal protection against mosquitoes.

    Full Text Available O processo de secagem de açafrão, atualmente utilizado pela grande maioria dos produtores agrícolas, consiste na exposição deste produto ao ar livre sobre uma lona plástica estendida sobre o solo, utilizando a radiação solar como fonte de energia para a secagem, sem nenhum tipo de aparato técnico para proteção contra a ação do tempo ou de animais. Sob estas condições de secagem, em um ambiente onde praticamente não há nenhum tipo de controle de temperatura e umidade, surgem vários problemas durante o processo, dentre os quais pode-se destacar o tempo demasiado longo para atingir o ponto final desejado, e paralelamente a isto o desenvolvimento de microrganismos nocivos à saúde e a alta deterioração do produto. Por estar sendo utilizado um ambiente ao ar livre e sem proteção contra a ação do tempo, fica também difícil a previsão do tempo de secagem. Desta forma, o período de secagem pode chegar a 25 dias, o qual é muito longo do ponto de vista industrial. Este trabalho apresenta um levantamento das curvas de secagem do açafrão para diferentes condições de temperatura, velocidade do ar e cortes do rizoma. Tais curvas apresentam a influência da casca, do tipo de corte, da temperatura e da velocidade do ar nos tempos de secagem, parâmetros importantes ao desenvolvimento de novos equipamentos e processos de secagem.The process currently used by most agricultural producers for drying Curcuma longa L. consists in the exposure of the product to atmospheric conditions, on a plastic film on the ground, using solar radiation as energy source for drying, without the use of any kind of apparatus for protection against the weather or animals.

    Turmeric ( Curcuma longa ) is reported to possess wide array of biological activities. Herbal Medicament (HM) is a standardized hexane-soluble fraction of C. longa and is well known for its neuroprotective effect. In this study, we attempted to synthesize a novel chemically modified bioactive fraction from HM (NCCL) along with isolation and characterization of a novel marker compound (I). NCCL was prepared from HM. The chemical structure of the marker compound isolated from NCCL was determined from 1D/2D nuclear magnetic resonance, mass spectroscopy, and Fourier transform infrared. The compound so isolated was subjected to in silico and in vitro screenings to test its inhibitory effect on estrogen receptors. Molecular docking studies revealed that the binding poses of the compound I was energetically favorable. Among NCCL and compound I taken for in vitro studies, NCCL had exhibited good anti-cancer activity over compound I against MCF-7, MDA-MB-231, DU-145, and PC-3 cells. This is the first study about the synthesis of a chemically modified bioactive fraction which used a standardized extract since the preparation of the HM. It may be concluded that NCCL fraction having residual components induce more cell death than compound I alone. Thus, NCCL may be used as a potent therapeutic drug. In the present paper, a standardized hexane soluble fraction of Curcuma longa (HM) was chemically modified to give a novel bioactive fraction (NCCL). A novel marker compound was isolated from NCCL and was characerized using various spectral techniques. The compound so isolated was investigated for in-silico screenings. NCCL and isolated compound was subjected to in-vitro anti-cancer screenings against MCF 7, MDA MB 231 (breast adenocarcinoma) and DU 145 and PC 3 cell lines (androgen independent human prostate cancer cells). The virtual screenings reveals that isolated compound has shown favourable drug like properties. NCCL fraction having residual components induces more cell

    Bacillus strains were isolated from termitarium soil and screened for their antifungal activity through the production of diffusible and volatile metabolites. Further, the bacterial strains that showed antifungal activity were evaluated for their biocontrol potential on the basis of their plant-growth-promoting attributes. Termitarium-inhabiting Bacillus strains TSH42 and TSH77 significantly reduced the growth of pathogenic fungus Fusarium solani, controlled the symptoms of rhizome rot in turmeric (Curcuma longa L.), and demonstrated various plant-growth-promoting traits in different in vitro assays. On the basis of morphological, physiological, biochemical, and 16S rDNA characteristics, isolates TSH42 and TSH77 were identified as Bacillus endophyticus (KT379993) and Bacillus cereus (KT379994), respectively. Through liquid chromatography - mass spectrometry analysis, acidified cell-free culture filtrate (CFCF) of B. cereus TSH77 was shown to contain surfactin and fengycin, while CFCF of B. endophyticus TSH42 contained iturin in addition to surfactin and fengycin. Treatment of the turmeric (C. longa L.) plants with TSH42 and TSH77 significantly reduced the percentage incidence of rhizome rot disease caused by F. solani. The same treatment also increased the fresh rhizome biomass and plant growth in greenhouse conditions.

    Curcumin and lawsone dyes extracted from turmeric (Curcuma longa L.) and henna (Lawsonia inermis L.) are used to investigate their possibility as photosensitizers on a TiO_2 photo electrode, respectively. The natural dyes undergo simple cold extraction techniques without further purification. The photochemical properties are studied by FT-IR spectroscopy and UV-Vis spectrophotometer. The FTIR spectra revealed that the presence of hydroxyl and carbonyl functional groups in both dyes indicated the presence of important characteristics in a sensitizer to graft on to TiO_2 photo electrode. The broad range of absorption peak wavelength obtained in this work shows that curcumin and lawsone are promising candidates for efficient sensitizers in dye-sensitized solar cells (DSSC). The maximum absorption peak attributed for curcumin and lawsone are 425 nm and 673 nm. The optical band gaps calculated are 2.48 eV and 1.77 eV, respectively. The findings indicated the potential of naturally obtained dyes to act as photosensitizers in DSSC. (author)

    The aim of this work is to assess the potential of curcumin in the photosensitization of biofilms of Listeria. Biofilms of Listeria innocua, were irradiated with blue light in the presence of a curcumin-rich extract of Curcuma longa or commercial curcumin. Similar experiments were conducted with planktonic cells, for comparison. A reduction of 4·9 log in the concentration of viable biofilm cells was obtained with 3·7 mg l -1 of commercial curcumin. Planktonic cells were much more susceptible (6·1 log reduction). A tetracationic porphyrin, used as a reference photosensitizer (PS), caused a very modest inactivation of the biofilm (1·1 log) and complete inactivation of the planktonic form (>8 log). Curcumin is an effective PS for the photodynamic control of Listeria biofilms and the inactivation efficiency attained with this natural compound is higher than with the porphyrin. This result may point to a better performance of type I PSs against bacterial biofilms by circumventing the limitations to singlet-oxygen diffusion imposed by the extracellular matrix. Curcumin represents a promising alternative to the control of bacteria and bacterial biofilms in food products particularly in the case of meat products in which turmeric is used as spice. © 2018 The Society for Applied Microbiology.

    To find the cure of world's one of the leading morbid and mortal disorders; diabetes mellitus and its most prevalent complication, 'diabetic-dyslipidemia', is one of the leading health challenges of 21st century. The use of phytomedicine is a glimmer of hope in this scenario. Studies of current decade have shown that methanolic extracts of Zingiber officinale and Curcuma longa have highly effective therapeutic potentials against the aforesaid disorders, however, which of the extracts has more potential is still unclear. Furthermore, synergistic effect of the extracts has never been studied. Forty-eight Albino adult rats of either sex were randomly divided into eight groups. A-D groups were containing healthy rats while E-H groups were of induced diabetic-dyslipidemic rats. For forty-two days, rats of each group were given either distilled water or Zingiber officinale methanolic extract (ZOME) or Curcuma longa methanolic extract (CLME) or ZOME+CLME therapies at dose rate of 300mg/100 mL dist. H 2 O/kg body wt/day. FPG and lipid profiles were estimated before and after the trial, and were statistically analyzed by one-way ANOVA along with Post-hoc Tukey's multiple comparison tests. Although, ZOME and CLME significantly (P<0.05) lowered fasting plasma glucose (FPG) levels and controlled lipid profiles in diabetic-dyslipidemic rats; yet, synergistic therapy of both extracts (ZOME+CLME) most significantly (P<0.05) controlled all parameters of diabetic-dyslipidemia (78.00±1.06mg/dL FPG, 62.00±0.58mg/dL TG, 66.50±0.76mg/dL cholesterol, 32.00±0.36mg/dL HDL, 22.43±0.64 mg/dL LDL, and 12.40±0.12mg/dL VLDL). Our findings may be useful to formulate new medicines having multiple potentials to control diabetes mellitus, dyslipidemia, and diabetic-dyslipidemia.

    Curcuminoid from Curcuma longa Linnaeus has been demonstrated to be effective in anti-cancer and anti-inflammation. The objectives of the present study were to prepare curcuminoid dispersion and nanoemulsion from C. longa and determine their oral bioavailabilities in rats. After curcuminoid extraction using 99.5% ethanol, bisdemethoxycurcumin (BDMC), demethoxycurcumin (DMC) and curcumin were separated within 10 min by high-performance liquid chromatography using an Eclipse XDB-C18 column (Agilent, Palo Alto, CA, USA) and a gradient mobile phase of 0.1% aqueous formic acid and acetonitrile, with a flow rate of 1 mL min -1 , column temperature of 35 °C and detection wavelength of 425 nm. Curcuminoid nanoemulsion at a particle size of 12.1 nm and encapsulation efficiency 98.8% was prepared using lecithin, Tween 80 and water. A pharmacokinetic study in rats revealed that the parameters including T max , C max , t 1/2 and the area under the curve were higher for curcuminoid nanoemulsions than for curcuminoid dispersion at the same dose employed for gavage administration, whereas, for intravenous injection, an opposite trend was shown. The oral bioavailabilities of BDMC, DMC, curcumin and total curcuminoids in nanoemulsion and dispersion were 34.39 and 4.65%, 39.93 and 5.49%, 47.82 and 9.38%, and 46 and 8.7%, respectively. The results of the present study demonstrate a higher oral bioavailability after incorporation of curcuminoid into nanoemulsion, facilitating its application as a botanic drug. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    The liver is a target for toxic chemicals such as cadmium (Cd). When the liver is damaged, hepatic stellate cells (HSC) are activated and transformed into myofibroblast-like cells, which are responsible for liver fibrosis. Curcuma longa has been reported to exert a hepato-protective effect under various pathological conditions. We investigated the effects of C. longa administration on HSC activation in response to Cd induced hepatotoxicity. Forty adult male albino rats were divided into: group 1 (control), group 2 (Cd treated), group 3 (C. longa treated) and group 4 (Cd and C. longa treated). After 6 weeks, liver specimens were prepared for light and electron microscopy examination of histological changes and immunohistochemical localization of alpha smooth muscle actin (αSMA) as a specific marker for activated HSC. Activated HSC with a positive αSMA immune reaction were not detected in groups 1 and 3. Large numbers of activated HSC with αSMA immune reactions were observed in group 2 in addition to Cd induced hepatotoxic changes including excess collagen deposition in thickened portal triads, interlobular septa with hepatic lobulation, inflammatory cell infiltration, a significant increase in Kupffer cells and degenerated hepatocytes. In group 4, we observed a significant decrease in HSC that expressed αSMA with amelioration of the hepatotoxic changes. C. longa administration decreased HSC activation and ameliorated hepatotoxic changes caused by Cd in adult rats.

    The purpose of this research is to investigate the effect of acidity on the energy level of curcumin dye. The natural dye, curcumin, was synthesized from Curcuma longa L. using a simple extraction technique. The purification of curcumin dye was conducted in a column of chromatography and its characteristics were studied. Next, the purified curcumin dye was added by benzoic acids until various acidities of 3.0, 3.5, 4.0, 4.5, and 5.0. The absorbance spectra and the functionality groups found in the dyes were detected by ultraviolet-visible spectroscopy and Fourier-transform infrared spectroscopy, respectively. Meanwhile, the energy level of the dyes, E{sub HOMO} and E{sub LUMO} was measured by cyclic voltammetry. The best energy level of curcumin dye was achieved at pH 3.5 where E{sub red} = −0.37V, E{sub LUMO} = −4.28 eV, E{sub ox} = 1.15V, E{sub HOMO} = −5.83 eV, and E{sub band} {sub gap} = 1.55 eV. Therefore, the purified curcumin dye added by benzoic acid was promising for sensitizing the dye-sensitized solar cells.

    Full Text Available Aim: Gastrointestinal helminthosis is a global problem in small ruminant production. Most parasites have developed resistance to commonly available anthelminthic compounds, and there is currently an increasing need for new compounds with more efficacies. This study evaluated the in vitro effects of ethanolic extract of Curcuma longa (EECL as a biological nematicide against third stage Haemonchus larvae (L3 isolated from sheep. Materials and Methods: Haemonchus L3 were cultured and harvested from the feces of naturally infected sheep. EECL was prepared and three concentrations; 50, 100, and 200 mg/mL were tested for their efficacies on Haemonchus L3. Levamisole at concentration 1.5 and 3 mg/mL were used as positive controls. Results: EECL showed anthelmintic activity in a dose-dependent manner with 78% worm mortality within 24 h of exposure at the highest dose rate of 200 mg/mL. There was a 100% worm mortality rate after 2 h of levamisole (3 mg/mL admisntration. However, there was a comparable larvicidal effect between when levamisole (1.5 mg/mL and EECL (200 mg were administered. Conclusion: The study shows that EECL does exhibit good anthelmintic properties at 200 mg/mL which is comparable with levamisole at 1.5 mg/mL.

    The purpose of this research was to evaluate the efficacy of a combination herbal product that is traditionally used for managing diabetes mellitus. Herbal drug contains Curcuma longa and Eugenia jambolanain the ratio of 1:1. It was orally administered at the dose of 1082 mg/70 kg twice a day for a period of 6 weeks to alloxan induced diabetic rats and compared with glibenclamide (standard). The effects of drug were observed at intervals, with respect to random and fasting glucose levels. HbA1C was also monitored after the drug treatment to monitor the overall diabetic effect. Results revealed that the combination of two herbs significantly reduced fasting and random glucose levels with HbA1C of less than 6% (p<0.001) in comparison to diabetic control. The control of fasting blood glucose levels by herbal combination is similar to the standard drug, glibenclamide (p<0.05). Random glucose levels by herbal combination is better than standard drug after one week and six weeks of treatment (p<0.01 and p<0.001 respectively) and similar after third week of treatment (p<0.05). Also, herbal drug combination showed HbA1C closer to the standard drug. It shows that this herbal combination can be of potential benefit in managing diabetes mellitus in future.

    2014-01-01

    The effect of balanced low pressure drying pretreatment associated with ultrasonication extraction (BU) on the enhancement of skin immune modulatory activities of Curcuma longa leaf was studied by comparing with conventional hot air drying (HE), freeze drying (FE) and balanced low pressure drying (BE) pretreatment processes. In considering skin immune activation activities such as the inhibition of hyaluronidase activity, the BU extract showed ca. 10% higher than those of HE, and even higher than that of the FE extract. Nitric oxide production from macrophage of the BU extract in adding 1.0 mg/mL was increased up to 16.5 μM. When measuring inhibition of IL-6 and TNF-a production from the human T lymphocytes (T cell), the BU extract also showed 53% and 78% of inhibition effect, respectively. It is found that the BU extract could effectively suppress the expression levels of skin inflammation related genes such as Cox-2 and iNOS, down to 80% and 85% compared to the control, respectively. Balanced low pressure drying process was especially active on dehydration of the leaves with minimizing the destruction and making easier elution of the bioactive substances, which resulted in higher extraction yield and better biological activities.

    The hepatoprotective effect of fermented Curcuma longa L. (FC) was investigated in rats under CCl4-induced oxidative stress. FC at a dose of 30 or 300 mg/kg body weight (b.w.) was orally administered for 14 days followed by a single dose of CCl4 (1.25 mL/kg b.w. in 20% corn oil) on day 14. Pretreatment with FC drastically prevented the elevated activities of serum AST, ALT, LDH, and ALP caused by CCl4-induced hepatotoxicity. Histopathologically evident hepatic necrosis was significantly ameliorated by FC pretreatment. When compared to the CCl4-alone treated group, rats pretreated with FC displayed the reduced level of malondialdehyde. Furthermore, FC enhanced antioxidant capacities with higher activities of catalase, glutathione-S-transferase, glutathione reductase, and glutathione peroxidase, and level of reduced glutathione. These results suggest that FC could be a candidate used for the prevention against various liver diseases induced by oxidative stress via elevating antioxidative potentials and decreasing lipid peroxidation.

    To optimize the optimal microwave-assisted extraction method of curcuminoids from Curcuma longa. On the base of single factor experiment, the ethanol concentration, the ratio of liquid to solid and the microwave time were selected for further optimization. Support Vector Regression (SVR) and Central Composite Design-Response Surface Methodology (CCD) algorithm were utilized to design and establish models respectively, while Particle Swarm Optimization (PSO) was introduced to optimize the parameters of SVR models and to search optimal points of models. The evaluation indicator, the sum of curcumin, demethoxycurcumin and bisdemethoxycurcumin by HPLC, were used. The optimal parameters of microwave-assisted extraction were as follows: ethanol concentration of 69%, ratio of liquid to solid of 21 : 1, microwave time of 55 s. On those conditions, the sum of three curcuminoids was 28.97 mg/g (per gram of rhizomes powder). Both the CCD model and the SVR model were credible, for they have predicted the similar process condition and the deviation of yield were less than 1.2%.

    This research examines the acid hydrolysis of Curcuma longa waste, to obtain the hydrolysate containing lactic acid and ethanol fermentative sugars. A central composite design for describing regression equations of variables was used. The selected optimum condition was 4.91% sulphuric acid, 122.68°C and 50 min using the desirability function under the following conditions: the maximum reducing sugar (RS) yield is within the limited range of the 5-hydroxymethylfurfural (HMF) and furfural concentrations. Under the condition, the obtained solution contained 144 g RS/L, 0.79 g furfural/L and 2.59 g HMF/L and was directly fermented without a detoxification step. The maximum product concentration, average productivity, RS conversion and product yield were 115.36 g/L, 2.88 g/L/h, 89.43% and 64% for L-lactic acid; 113.92 g/L, 2.59 g/L/h, 88.31% and 63.29% for D-lactic acid; and 55.03 g/L, 1.38 g/L/h, 42.66 and 30.57%, respectively, for ethanol using a 7-L jar fermenter.

    The rhizome of Curcuma longa (CL) has been commonly used in Asia as a potential candidate for the treatment of different diseases, including inflammatory disorders and cancers. The present study evaluated the anti-proliferative activities of the isolated compounds (3 curcuminoids and 2 turmerones) from CL, using human cancer cell lines HepG2, MCF-7 and MDA-MB-231. The immunomodulatory activities of turmerones (α and aromatic) isolated from CL were also examined using human peripheral blood mononuclear cells (PBMC). Our results showed that the curcuminoids (curcumin, demethoxycurcumin and bisdemethoxycurcumin) and α-turmerone significantly inhibited proliferation of cancer cells in dose-dependent manner. The IC50 values of these compounds in cancer cells ranged from 11.0–41.8 μg/ml. Alpha-turmerone induced MDA-MB-231 cells to undergo apoptosis, which was confirmed by annexin-V & propidium iodide staining, and DNA fragmentation assay. The caspase cascade was activated as shown by a significant decrease of procaspases-3, -8 and -9 in α-turmerone treated cells. Both α-turmerone and aromatic-turmerone showed stimulatory effects on PBMC proliferation and cytokine production. The anti-proliferative effect of α-turmerone and immunomodulatory activities of ar-turmerone were shown for the first time. The findings revealed the potential use of CL crude extract (containing curcuminoids and volatile oil including turmerones) as chemopreventive agent. PMID:20438793

    The purpose of this research is to investigate the effect of acidity on the energy level of curcumin dye. The natural dye, curcumin, was synthesized from Curcuma longa L. using a simple extraction technique. The purification of curcumin dye was conducted in a column of chromatography and its characteristics were studied. Next, the purified curcumin dye was added by benzoic acids until various acidities of 3.0, 3.5, 4.0, 4.5, and 5.0. The absorbance spectra and the functionality groups found in the dyes were detected by ultraviolet-visible spectroscopy and Fourier-transform infrared spectroscopy, respectively. Meanwhile, the energy level of the dyes, E_H_O_M_O and E_L_U_M_O was measured by cyclic voltammetry. The best energy level of curcumin dye was achieved at pH 3.5 where E_r_e_d = −0.37V, E_L_U_M_O = −4.28 eV, E_o_x = 1.15V, E_H_O_M_O = −5.83 eV, and E_b_a_n_d _g_a_p = 1.55 eV. Therefore, the purified curcumin dye added by benzoic acid was promising for sensitizing the dye-sensitized solar cells.

    Curcuma has long been used as an anti-inflammatory agent in inflammatory bowel disease. Since gastrointestinal motility is impaired in inflammatory states, the aim of this work was to evaluate if Curcuma Longa had any effect on intestinal motility. The biological activity of Curcuma extract was evaluated against Carbachol induced contraction in isolated mice intestine. Acute and chronic colitis were induced in Balb/c mice by Dextran Sulphate Sodium administration (5% and 2.5% respectively) and either Curcuma extract (200 mg/kg/day) or placebo was thereafter administered for 7 and 21 days respectively. Spontaneous contractions and the response to Carbachol and Atropine of ileum and colon were studied after colitis induction and Curcuma administration. Curcuma extract reduced the spontaneous contractions in the ileum and colon; the maximal response to Carbachol was inhibited in a non-competitive and reversible manner. Similar results were obtained in ileum and colon from Curcuma fed mice. DSS administration decreased the motility, mainly in the colon and Curcuma almost restored both the spontaneous contractions and the response to Carbachol after 14 days assumption, compared to standard diet, but a prolonged assumption of Curcuma decreased the spontaneous and Carbachol-induced contractions. Curcuma extract has a direct and indirect myorelaxant effect on mouse ileum and colon, independent of the anti-inflammatory effect. The indirect effect is reversible and non-competitive with the cholinergic agent. These results suggest the use of curcuma extract as a spasmolytic agent.

    The essential oil from Curcuma longa L. was analysed by GC/MS. The major components of the oil were ar-turmerone (33.2%), α-turmerone (23.5%) and β-turmerone (22.7%). The antifungal activities of the oil were studied with regard to Aspergillus flavus growth inhibition and altered morphology, as preliminary studies indicated that the essential oil from C. longa inhibited Aspergillus flavus Link aflatoxin production. The concentration of essential oil in the culture media ranged from 0.01% to 5.0% v/v, and the concentration of curcumin was 0.01–0.5% v/v. The effects on sporulation, spore viability, and fungal morphology were determined. The essential oil exhibited stronger antifungal activity than curcumin on A. flavus. The essential oil reduced the fungal growth in a concentration-dependent manner. A. flavus growth rate was reduced by C. longa essential oil at 0.10%, and this inhibition effect was more efficient in concentrations above 0.50%. Germination and sporulation were 100% inhibited in 0.5% oil. Scanning electron microscopy (SEM) of A. flavus exposed to oil showed damage to hyphae membranes and conidiophores. Because the fungus is a plant pathogen and aflatoxin producer, C. longa essential oil may be used in the management of host plants. PMID:24367241

    Ichthyophthirius multifiliis is a ciliated parasite that elicits great economic losses in aquaculture. In the present study, a polyphenol compound, curcumin, was obtained from the rhizome of Curcuma longa by bioassay-guided isolation based on the efficacy of anti-I. multifiliis theronts. Anti-I. multifiliis efficacy of curcumin was evaluated in vitro and in vivo. Curcumin resulted in 100% mortality of I. multifiliis theronts at a concentration of 1mg/L within 21.7±1.2min and killed all tomonts at 8mg/L within 31.0±1.0min. Curcumin at 4mg/L for 16h exposure can completely terminate the reproduction of tomonts. The pretreatment with curcumin at concentrations of 0.5, 0.25, and 0.125mg/L for 2h significantly reduced the infectivity of I. multifiliis theronts. Curcumin at 4mg/L completely cured the infected grass carp and protected naive fish from I. multifiliis infection after 10days exposure. The 4h median effective concentration (EC 50 ) of curcumin to I. multifiliis theronts and the 5h EC 50 of curcumin to I. multifiliis tomonts were 0.303mg/L and 2.891mg/L, respectively. The 96h median lethal concentration (LC 50 ) of curcumin to grass carp was 56.8mg/L, which was approximately 187.4 times EC 50 of curcumin to theronts and 19.6 times EC 50 of curcumin to tomonts. The results demonstrated that curcumin has the potential to be a safe and effective therapeutant for controlling ichthyophthiriasis in aquaculture. Copyright © 2017 Elsevier B.V.

    The effect of certain food additives on aflatoxin production by Aspergillus parasiticus has been studied in vitro. Extracts of turmeric (Curcuma longa), garlic (Allium sativum) and asafoetida (Ferula asafoetida) inhibited the aflatoxin production considerably (more than 90%) at concentrations of 5-10 mg/ml. Similar results were also seen using butylated hydroxytoluene, butylated hydroxyanisole and ellagic acid at concentration 0.1 mM. Curcumin, the antioxidant principle from Curcuma longa did not have any effect on aflatoxin production. Turmeric and curcumin were also found to reverse the aflatoxin induced liver damage produced by feeding aflatoxin B1 (AFB1) (5 micrograms/day per 14 days) to ducklings. Fatty changes, necrosis and biliary hyperplasia produced by AFB1 were considerably reversed by these food additives.

    For this study, we examined the effects of curcumin against acute and chronic stress, paying specific attention to ROS. We also aimed to clarify the differences between acute and chronic stress conditions. We investigated the effects of curcumin against acute stress (once/1 day CCl 4 treatment) and chronic-stress (every other day/4week CCl 4 treatment). Compared with acute stress, in which the antioxidant system functioned properly and aspartate transaminase (AST) and ROS production increased, chronic stress increased AST, alanine aminotransferase (ALT), hepatic enzymes, and ROS more significantly, and the antioxidant system became impaired. We also found that ER-originated ROS accumulated in the chronic model, another difference between the two conditions. ER stress was induced consistently, and oxidative intra-ER protein folding status, representatively PDI, was impaired, especially in chronic stress. The PDI-associated client protein hepatic apoB accumulated with the PDI-binding status in chronic stress, and curcumin recovered the altered ER folding status, regulating ER stress and the resultant hepatic dyslipidemia. Throughout this study, curcumin and curcumin-rich Curcuma longa L. extract promoted recovery from CCl 4 -induced hepatic toxicity in both stress conditions. For both stress-associated hepatic dyslipidemia, curcumin and Curcuma longa L. extract might be recommendable to recover liver activity.

    Background Many plant-derived products exhibit potent chemopreventive activity against animal tumor models as well as rodent and human cancer cell lines. They have low side effects and toxicity and presumably modulate the factors that are critical for cell proliferation, differentiation, senescence and apoptosis. The present study investigates the effects of some medicinal plant extracts from generally recognized as safe plants that may be useful in the prevention and treatment of cancer. Methods Clonogenic assays using logarithmically-growing cells were performed to test the effect. The cytotoxic effects of Curcuma longa and Zingiber officinale were studied using sulforhodamine B assay, tetrazolium dye assay, colony morphology and microscopic analysis. Results Out of the 13 lyophilized plant-derived extracts evaluated for growth-inhibitory effects on the PC-3M prostate cancer cell line, two extracts derived from C. longa and Z. officinale showed significant inhibitory effects on colony-forming ability. The individual and augmentative effects of these two extracts were tested for their narrow range effective lower concentration on PC-3M in clonogenic assays. At relatively lower concentrations, C. longa showed significant inhibition of colony formation in clonogenic assays; whereas at same concentrations Z. officinale showed only moderate inhibitory effects. However, when both the agents were tested together at the same concentrations, the combined effects were much more significant than their individual ones. On normal prostate epithelial cells both C. longa and Z. officinale had similar effects but at a lower magnitude. These observations were confirmed by several cytotoxicity assays involving the morphological appearance of the colonies, microscopic observations, per cent inhibition in comparison to control by sulforhodamine B and tetrazolium dye assay. Conclusions From these observations, it was concluded that the combined effects of C. longa and Z. officinale

    To fully understand the chemical diversity of an herbal medicine is challenging. In this work, we describe a new approach to globally profile and discover novel compounds from an herbal extract using multiple neutral loss/precursor ion scanning combined with substructure recognition and statistical analysis. Turmeric (the rhizomes of Curcuma longa L.) was used as an example. This approach consists of three steps: (i) multiple neutral loss/precursor ion scanning to obtain substructure information; (ii) targeted identification of new compounds by extracted ion current and substructure recognition; and (iii) untargeted identification using total ion current and multivariate statistical analysis to discover novel structures. Using this approach, 846 terpecurcumins (terpene-conjugated curcuminoids) were discovered from turmeric, including a number of potentially novel compounds. Furthermore, two unprecedented compounds (terpecurcumins X and Y) were purified, and their structures were identified by NMR spectroscopy. This study extended the application of mass spectrometry to global profiling of natural products in herbal medicines and could help chemists to rapidly discover novel compounds from a complex matrix.

    Curcuma longa is the scientific name of turmeric, which can be found on spice racks worldwide. This herb is responsible for the yellow colouring of many curry dishes. In the present study, female albino rats were treated with oral administration of curcumin for 14 days before gamma irradiation. Gamma radiation was applied in 0.1, 0.75 and 2 Gy, 1 hour after the last dose of curcuma administration. Animals were divided into control and 6 treated groups, all were irradiated with gamma rays, only three were injected with curcumin. Blood was collected 1 and 48 hours after irradiation. Serum total protein, albumin, globulins, cholesterol, triglycerides, SGOT and SGPT were determined. Curcuma was found to elevate the protein profile (total protein, albumin and globulin) and ameliorated the hyperlipidaemic effects of gamma radiation. Curcuma also improved the liver functions affected by gamma irradiation. It could be concluded that curcuma can be used as a radioprotector for occupationally exposed individuals to low doses and low dose rates

    The accumulation of advanced glycationend products (AGE's) in the body, due to the non-enzymatic glycation of proteins is associated with several pathological conditions like aging and diabetes mellitus. Hence a plant having anti-glycation and anti-oxidation potentials may serve as therapeutic agent for diabetic complications and aging. In this study the anti-glycation and anti-oxidation properties of crude methanolic extracts of fruits of Capsicum frutescens and Curcuma longa were investigated. Among the two C. frutescens had more anti-glycation ability with a minimum inhibitory concentration (MIC50) of 90βg/mLas compared to 324βg/mL MIC50 of C. longa. Curcuma longa had the more anti-oxidation potential i.e. 35.01, 30.83 and 28.08% at 0.5mg, 0.25mg and 0.125mg respectively.

    Streptozotocin-induced diabetic rats were maintained on 0.5% curcumin containing diet for 8 weeks. Blood cholesterol was lowered significantly by dietary curcumin in these diabetic animals. Cholesterol decrease was exclusively from LDL-VLDL fraction. Significant decrease in blood triglyceride and phospholipids was also brought about by dietary curcumin in diabetic rats. In a parallel study, wherein diabetic animals were maintained on a high cholesterol diet, the extents of hypercholesterolemia and phospholipidemia were still higher compared to those maintained on control diet. Curcumin exhibited lowering of cholesterol and phospholipid in these animals also. Liver cholesterol, triglyceride and phospholipid contents were elevated under diabetic conditions. Dietary curcumin showed a distinct tendency to counter these changes in lipid fractions of liver. This effect of curcumin was also seen in diabetic animals maintained on high cholesterol diet. Dietary curcumin also showed significant countering of renal cholesterol and triglycerides elevated in diabetic rats. In order to understand the mechanism of hypocholesterolemic action of dietary curcumin, activities of hepatic cholesterol-7a-hydroxylase and HMG CoA reductase were measured. Hepatic cholesterol-7a-hydroxylase activity was markedly higher in curcumin fed diabetic animals suggesting a higher rate of cholesterol catabolism.

    We explored, using nuclear magnetic resonance (NMR) metabolomics and fatty acids profiling, the effects of a common nutritional complement, Curcuma longa, at a nutritionally relevant dose with human use, administered in conjunction with an unbalanced diet. Indeed, traditional food supplements have been long used to counter metabolic impairments induced by unbalanced diets. Here, rats were fed either a standard diet, a high level of fructose and saturated fatty acid (HFS) diet, a diet common to western countries and that certainly contributes to the epidemic of insulin resistance (IR) syndrome, or a HFS diet with a Curcuma longa extract (1% of curcuminoids in the extract) for ten weeks. Orthogonal projections to latent structures discriminant analysis (OPLS-DA) on the serum NMR profiles and fatty acid composition (determined by GC/MS) showed a clear discrimination between HFS groups and controls. This discrimination involved metabolites such as glucose, amino acids, pyruvate, creatine, phosphocholine/glycerophosphocholine, ketone bodies and glycoproteins as well as an increase of monounsaturated fatty acids (MUFAs) and a decrease of n-6 and n-3 polyunsaturated fatty acids (PUFAs). Although the administration of Curcuma longa did not prevent the observed increase of glucose, triglycerides, cholesterol and insulin levels, discriminating metabolites were observed between groups fed HFS alone or with addition of a Curcuma longa extract, namely some MUFA and n-3 PUFA, glycoproteins, glutamine, and methanol, suggesting that curcuminoids may act respectively on the fatty acid metabolism, the hexosamine biosynthesis pathway and alcohol oxidation. Curcuma longa extract supplementation appears to be beneficial in these metabolic pathways in rats. This metabolomic approach highlights important serum metabolites that could help in understanding further the metabolic mechanisms leading to IR.

    The Curcuma longa L. (CLL) rhizome has long been used to treat patients with hepatic dysfunction. CLL is a member of the ginger family of spices that are widely used in China, India, and Japan, and is a common spice, coloring, flavoring, and traditional medicine. This study was performed to evaluate the hepatoprotective activity of CLL extract and its active component curcumin in an acute carbon tetrachloride (CCl 4 )-induced liver stress model. Acute hepatic stress was induced by a single intraperitoneal injection of CCl 4 (0.1 ml/kg body weight) in rats. CLL extract was administered once a day for 3 days at three dose levels (100, 200, and 300 mg/kg/day) and curcumin was administered once a day at the 200 mg/kg/day. We performed alanine transaminase (ALT) and aspartate transaminase (AST). activity analysis and also measured total lipid, triglyceride, and cholesterol levels, and lipid peroxidation. At 100 g CLL, the curcuminoid components curcumin (901.63 ± 5.37 mg/100 g), bis-demethoxycurcumin (108.28 ± 2.89 mg/100 g), and demethoxycurcumin (234.85 ± 1.85 mg/100 g) were quantified through high liquid chromatography analysis. In CCl 4 -treated rats, serum AST and ALT levels increased 2.1- and 1.2-fold compared with the control. AST but not ALT elevation induced by CCl 4 was significantly alleviated in CLL- and curcumin-treated rats. Peroxidation of membrane lipids in the liver was significantly prevented by CLL (100, 200, and 300 mg/kg/day) on tissue lipid peroxidation assay and immunostaining with anti-4HNE antibody. We found that CLL extract and curcumin exhibited significant protection against liver injury by improving hepatic superoxide dismutase (p < 0.05) and glutathione peroxidase activity, and glutathione content in the CCl 4 -treated group (p < 0.05), leading to a reduced lipid peroxidase level. Our data suggested that CLL extract and curcumin protect the liver from acute CCl 4 -induced injury in a rodent model by suppressing

    Effect of Curcuma longa rhizome powder and its ethanolic extract on CYP2D6 and CYP3A4 metabolic activity was investigated in vitro using human liver microsomes and clinically in healthy human subjects. Dextromethorphan (DEX) was used as common probe for CYP2D6 and CYP3A4 enzymes. Metabolic activity of CYP2D6 and CYP3A4 was evaluated through in vitro study; where microsomes were incubated with NADPH in presence and absence of Curcuma extract. In clinical study phase-I, six healthy human subjects received a single dose (30 mg) of DEX syrup, and in phase-II DEX syrup was administered with Curcuma powder. The enzyme CYP2D6 and CYP3A4 mediated O- and N-demethylation of dextromethorphan into dextrorphan (DOR) and 3-methoxymorphinan (3-MM), respectively. Curcuma extract significantly inhibited the formation of DOR and 3-MM, in a dose-dependent and linear fashion. The 100 μg/ml dose of curcuma extract produced highest inhibition, which was about 70 % for DOR and 80 % for 3-MM. Curcuma significantly increases the urine metabolic ratio of DEX/DOR but the change in DEX/3-MM ratio was statistically insignificant. Present findings suggested that curcuma significantly inhibits the activity of CYP2D6 in in vitro as well as in vivo; which indicates that curcuma has potential to interact with CYP2D6 substrates.

    Full Text Available Curcuma longa (Turmeric, belonging to Zingiberaceae family is one of the most useful herbal medicinal plants. Extensive researches have proven that most of the turmeric activities of the turmeric are due to curcumin. It has various useful properties with antioxidant activities and is useful in conditions such as inflammation, ulcer and cancer. It also has antifungal, antimicrobial renal and hepatoprotective activities. Therefore, it has the potential against various cancer, diabetes, allergies, arthritis, Alzheimer’s disease and other chronic and hard curable diseases. The purpose of this review was to provide a brief summary of the new and current knowledge of the effects of curcumin. The recently published papers in international cites such as PubMed/Medline, Science Citation Index and Google Scholar about turmeric were searched. Recent studies have authenticated the use of turmeric for various diseases especially oxidative stress induced ones such as cancer, diabetes mellitus and inflammatory disorders. It also is used as hepatoprotective, nephroprotective, anticoagulant and anti-HIV to combat AIDS. Curcumin, as a spice, exhibits great promise as a therapeutic agent. It has very low toxicity, too. As the global scenario is now changing towards the use of non-toxic plant products having traditional medicinal use, development of modern drugs from turmeric should be emphasized for the control of various diseases. Further evaluation needs to be carried out on turmeric in order to explore the concealed areas and their practical clinical applications, which can be used for the welfare of mankind.

    Turmeric (Curcuma longa) is a wild plant of the ginger family native to tropical South Asia. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science have been searched. Emerging evidence indicate that turmeric/curcumin inhibits cytokines and TGF-β production. From the various factors involved in the genesis of chronic kidney disease and pathogenesis of primary and secondary glomerulonehritis, TGF-β has emerged as a key factor in the cascade of events. Leading to glomerulosclerosis, tubulointerstitial fibrosis and end-stage renal disease. considering the inhibitory effect of turmeric/curcumin on cytokines and TGF-β, it seems wise to assume that supplementary turmeric/curcumin might be a candidate remedy for chronic kidney disease and possibly prevention of subsequent end stage renal disease.

    Three commercial broiler breeds were fed from hatch with a diet supplemented with Capsicum and Curcuma longa oleoresins, and co-infected with Eimeria maxima and Clostridium perfringens to induce necrotic enteritis (NE). Pyrotag deep sequencing of bacterial 16S rRNA showed that gut microbiota compositions were quite distinct depending on the broiler breed type. In the absence of oleoresin diet, the number of operational taxonomic units (OTUs), was decreased in infected Cobb, and increased in Ross and Hubbard, compared with the uninfected. In the absence of oleoresin diet, all chicken breeds had a decreased Candidatus Arthromitus, while the proportion of Lactobacillus was increased in Cobb, but decreased in Hubbard and Ross. Oleoresin supplementation of infected chickens increased OTUs in Cobb and Ross, but decreased OTUs in Hubbard, compared with unsupplemented/infected controls. Oleoresin supplementation of infected Cobb and Hubbard was associated with an increased percentage of gut Lactobacillus and decreased Selenihalanaerobacter, while Ross had a decreased fraction of Lactobacillus and increased Selenihalanaerobacter, Clostridium, Calothrix, and Geitlerinema. These results suggest that dietary Capsicum/Curcuma oleoresins reduced the negative consequences of NE on body weight and intestinal lesion, in part, through alteration of the gut microbiome in 3 commercial broiler breeds.

In addition, human bronchus epithelial cell line BEAS-2B (normal cell was selected for comparison. A high-performance liquid chromatography (HPLC method was developed to separate and quantify the various curcuminoids in C. longa extract, including curcumin (1,714.5 µg/mL, demethoxycurcumin (1,147.4 µg/mL, and bisdemethoxycurcumin (190.2 µg/mL. A high-stability nanoemulsion composed of Tween 80, water, and curcuminoid extract was prepared, with mean particle size being 12.6 nm. The cell cycle was retarded at G2/M for both the curcuminoid extract and nanoemulsion treatments; however, the inhibition pathway may be different. H460 cells were more susceptible to apoptosis than A549 cells for both curcuminoid extract and nanoemulsion treatments. Growth of BEAS-2B remained unaffected for both the curcuminoid extract and nanoemulsion treatments, with a concentration range from 1 to 4 µg/mL. Also, the activities of caspase-3, caspase-8, and caspase-9 followed a dose-dependent increase for both A549 and H460 cells for both the treatments, accompanied by a dose-dependent increase in cytochrome C expression and a dose-dependent decrease in CDK1 expression. Interestingly, a dose-dependent increase in cyclin B expression was shown for A549 cells for both the treatments, while a reversed trend was found for H460 cells. Both mitochondria and death receptor pathways may be responsible for apoptosis of both A549 and H460 cells.Keywords: curcuminoid extract, curcuminoid nanoemulsion, Curcuma longa Linnaeus, lung cancer cell, cell cycle, apoptosis mechanism

    In order to increase the use of natural source and variation of naturalpigment for textile dyes, research activity has been carried out in productdiversification of turmeric for textile dyes however its fixation ability tocotton fibre in this dyes does not have strong fixation ability to cottonfibre in order to improve its colour fastness it was necessary to do aftertreatment with mordant. Up to present time, it has been well known thatturmeric was used as raw material for medicine and cosmetic. Considering thatturmeric contains of carbonyl as chromophore in natural pigment. it has highpossibility to serve it as textile dyes. In this study, turmeric wasextracted with water and used its yields for dyeing cotton fabrics. Theextraction was carried out by using water as medium with ratio of 1 : 4 byboiling until reaching the medium ratio of 1 : 2. The extracted turmeric wasre-extracted again with fresh water in the same condition as the previousextraction and repeating the process up to several times until no more dyeswill be extracted out. The mixture of the extracted dyes were then put intoevaporation to obtain dry pigment and was grinned to obtain powder dyes.Color measurement by means of spectrophotometry was subjected to the dyespowder from known various concentrations to obtain the linear calibrationcurve between dyes concentrations and absorbance. The linear equationobtained from this experiment was : Y = 0.0075 + 0.0435 X. From this equationit was calculated that the dyes yields from the whole turmeric extraction was2.6805 %, and from 3 times repeating extraction was 2.2648 % or 84.49 % fromthe whole extracted dyes. Dyeing experiment for cotton fabrics were carriedout at 60 o C for various times of dyeing (30 minutes to 120 minutes). Thedyed fabrics were then mordanted or after treatment with respected potassiumbichromate, aluminum potassium sulphate (Tawas), and diazonium salt (Red SaltB). The dyed fabrics and the mordanted ones were tested for color fastness

    Curcuma extract exerts a myorelaxant effect on the mouse intestine. In view of a possible use of curcuma extract in motor functional disorders of the gastrointestinal tract, a safety profile study has been carried out in the mouse. Thirty mice were used to study the in vitro effect of curcuma on gallbladder, bladder, aorta and trachea smooth muscular layers and hearth inotropic and chronotropic activity. The myorelaxant effect on the intestine was also thoroughly investigated. Moreover, curcuma extract (200 mg/Kg/day) was orally administered to twenty mice over 28 days and serum liver and lipids parameters were evaluated. Serum, bile and liver bile acids qualitative and quantitative composition was were also studied. In the intestine, curcuma extract appeared as a not competitive inhibitor through cholinergic, histaminergic and serotoninergic receptors and showed spasmolytic effect on K(+) induced contraction at the level of L type calcium channels. No side effect was observed on bladder, aorta, trachea and heart when we used a dose that is effective on the intestine. An increase in gallbladder tone and contraction was observed. Serum liver and lipids parameters were normal, while a slight increase in serum and liver bile acids concentration and a decrease in bile were observed. Although these data are consistent with the safety of curcuma extract as far as its effect on the smooth muscular layers of different organs and on the heart, the mild cholestatic effect observed in absence of alteration of liver function tests must be further evaluated and the effective dose with minimal side effects considered.

    A target cell extraction-chemical profiling method based on human alveolar adenocarcinoma cell line (A549 cells) and UHPLC/LTQ Orbitrap MS for screening the anti-lung cancer bioactive compounds from Curcuma longa has been developed in this paper. According to the hypothesis that when cells are incubated together with the extract of Curcuma longa, the potential bioactive compounds in the extract should selectively combine with the cells, then the cell-binding compounds could be separated and analyzed by LC-MS. The bioactive compounds in C. longa are lipophilic components. They intend to be absorbed on the inner wall of cell culture flask when they were incubated with A549 cells, which will produce interference in the blank solution. In this paper, by using cells digestion and multi-step centrifugation and transfer strategy, the interference problem has been solved. Finally, using the developed method, three cell-binding compounds were screened out and were identified as bisdemethoxycurcumin, demethoxycurcumin, and curcumin. These compounds are the main bioactive compounds with anti-lung cancer bioactivity in C. longa. The improved method developed in this paper could avoid the false positive results due to the absorption of lipophilic compounds on the inner wall of cell culture flask, which will to be an effective complementary method for current target cell extraction-chemical profiling technology.

    Inflammation and oxidative stress is considered to have a crucial role in induction of nephropathy. Curcuma longa (C. longa) and Nigella sativa (N. sativa) have anti-inflammatory and antioxidant effects. This study was designed to investigate the effect of mixed hydro-alcoholic extract of N.sativa and C. longa on the oxidative stress induced by Adriamycin (ADR) in rat kidney. The animals were divided into 6 groups: control (CO), ADR, Adriamycin+ Vitamin C (ADR+VIT C), C. longa extract+ Adriamycin (C.LE+ADR), N. sativa extract+ Adriamycin (N.SE+ADR) and C. longa extract+ N. sativa extract + Adriamycin (N.S+C.L+ADR). ADR (5mg/kg) was injected intravenously, whereas VITC (100mg/kg) and extract of C. longa (1000mg/kg) and N. sativa (200mg/kg) were administrated orally. Finally, the renal tissue, urine and blood samples were collected and submitted to measure of redox markers, osmolarity and renal index. The renal content of total thiol and superoxide dismutase (SOD) activity significantly decreased and Malondialdehyde (MDA) concentration increased in Adriamycin group compared to control group. The renal content of total thiol and SOD activity significantly enhanced and MDA concentration reduced in treated-mixed extract of C. longa and N. sativa along with ADR group compared to ADR group. The mixed extract did not restore increased renal index percentage induced by ADR. There also was no significant difference in urine and serum osmolarity between the groups. hydro-alcoholic extracts of N.sativa and C.longa led to an improvement in ADR-induced oxidative stress and mixed administration of the extracts enhanced the aforementioned therapeutic effect.

Therefore, the search for new compounds with antimicrobial properties is relevant in modern studies, particularly against bacteria of clinical interest. In the present study, in vitro antibacterial activity of the ethanol extract and essential oil of Curcuma longa (Zingiberaceae) was evaluated against nosocomial bacteria, using the microdilution method. Escherichia coli strains, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus sp. were used, Salmonella sp. and Bacillus sp., isolated from nosocomial infections in a hospital in the city of Monteria and reference strains of S. aureus ATCC 43300, S. aureus ATCC 29213, S. aureus ATCC 25923, P. aeruginosa ATCC 27853, E. coli ATCC 25922 and K. pneumonia ATCC 700603. The ethanol extract antibacterial profile was more efficient at higher concentrations (1 000 ppm), obtaining significant percentages of reduction of more than 50 % against K. pneumoniae ATCC 700603 and a clinical isolate of E. coli; while compared to Bacillus clinical isolate, was more active than the essential oil. For the rest of microorganisms, the reduction percentages obtained at a concentration of 1 000 ppm varied between 17 and 42 % with ethanolic extract, and 8 to 43 % with essential oil. At concentrations of 100 and 500 ppm antibacterial activity of the extracts was lower. The results indicated that the ethanolic extract and essential oil of C. longa rhizomes have active compounds with antibacterial properties that could be used in future research as a therapeutic alternative for the treatment of infections caused by nosocomial pathogens.

    The objectives of this study were to explore the inhibition mechanism of lung cancer cells A549 and H460 by curcuminoid extracts and nanoemulsions prepared from Curcuma longa Linnaeus. In addition, human bronchus epithelial cell line BEAS-2B (normal cell) was selected for comparison. A high-performance liquid chromatography (HPLC) method was developed to separate and quantify the various curcuminoids in C. longa extract, including curcumin (1,714.5 μg/mL), demethoxycurcumin (1,147.4 μg/mL), and bisdemethoxycurcumin (190.2 μg/mL). A high-stability nanoemulsion composed of Tween 80, water, and curcuminoid extract was prepared, with mean particle size being 12.6 nm. The cell cycle was retarded at G2/M for both the curcuminoid extract and nanoemulsion treatments; however, the inhibition pathway may be different. H460 cells were more susceptible to apoptosis than A549 cells for both curcuminoid extract and nanoemulsion treatments. Growth of BEAS-2B remained unaffected for both the curcuminoid extract and nanoemulsion treatments, with a concentration range from 1 to 4 μg/mL. Also, the activities of caspase-3, caspase-8, and caspase-9 followed a dose-dependent increase for both A549 and H460 cells for both the treatments, accompanied by a dose-dependent increase in cytochrome C expression and a dose-dependent decrease in CDK1 expression. Interestingly, a dose-dependent increase in cyclin B expression was shown for A549 cells for both the treatments, while a reversed trend was found for H460 cells. Both mitochondria and death receptor pathways may be responsible for apoptosis of both A549 and H460 cells.

    Giardiosis is one of the common parasitic diarrhoea in humans, especially in children, worldwide. Many drugs are used for its treatment, but there is evidence of drug resistance, insufficient efficacy and unpleasant side effects. Natural products are good candidates for discovering more effective anti-giardial compounds. This study evaluated the activity of extracts of Zingiber officinale (ginger) and Curcuma longa (curcumin) against Giardia lamblia in vitro and in vivo. Giardia cyst suspension was prepared from children faecal specimens. For the in vitro experiment, 1, 10 and 50 mg⁄mL dichloromethane extracts of ginger and curcumin separately were incubated with Giardia cysts for 5, 10, 30 and 60 min. The viability was distinguished by 0.1 % eosin and a haemocytometer. For the in vivo experiments, Balb/c mice were infected with Giardia cyst suspension containing 10,000 cysts/mL. Infected mice were administered 10 and 20 mg kg(-1) day(-1) ginger and curcumin extracts separately for 7 days post-infection. The effectiveness of the extracts was evaluated by faecal cyst and intestinal trophozoite counts and histopathological examination of the small intestine. In vitro ginger extract had a higher significant effect on cyst viability than curcumin, in a dose- and time-dependent manner. In vivo ginger (more effective) and curcumin extracts significantly treated infected mice, and this was evidenced by the faecal cyst and intestinal trophozoite counts reduction, in addition to evident improvement of intestinal mucosal damages induced by Giardia infection. Z. officinale and C. longa extracts may represent effective and natural therapeutic alternatives with low side effects and without drug resistance in the treatment of giardiosis.

    Allergies are a problem that greatly affects the population, and hence the use of antiallergic medications is fairly widespread. However, these drugs have many adverse effects. The use of medicinal plants could be an option, but they need to be evaluated. This study was designed to evaluate the antiallergic effect of the atomized extract of rhizome of Curcuma longa , flowers of Cordia lutea , and leaves of Annona muricata . Twenty-four New Zealand white albino rabbits were randomized into 2 groups. Group A received the atomized extract diluted in physiological saline (APS) and group B received it diluted in Freund's adjuvant (FA). Then, the back of each rabbit was divided into 4 quadrants. The A-I quadrant received only physiological saline. The A-I quadrants of each rabbit conformed the PS group. The following 3 quadrants received the APS in 10 μg/mL, 100 μg/mL, and 1,000 μg/mL, respectively. The B-I quadrant received only FA. The B-I quadrants of each rabbit conformed the FA group. The following 3 quadrants received the AFA in 10 μg/mL, 100 μg/mL, and 1,000 μg/mL, respectively. The occurrence of erythema and edema was recorded according to the Draize scoring system and the primary irritation index. After 72 hours, biopsies were performed. The AFA group presented significantly less erythema and edema compared to the FA group ( P <0.05). The histopathologic evaluation at 72 hours showed normal characteristics in the APS group. Considering the clinical and histopathological signs, we conclude that the administration of the atomized extract of rhizome of C. longa , flowers of C. lutea , and leaves of A. muricata lacks antigenic effect but could have an antiallergenic effect in a model of dermal irritation in rabbits.

    In its powdered form, turmeric [Curcuma longa L. (Zingiberaceae)], a spice of medical importance, is often adulterated lowering its quality. The study sought to detect plant-based adulterants in traded turmeric powder using DNA barcoding. Accessions of Curcuma longa L., Curcuma zedoaria Rosc. (Zingiberaceae), and cassava starch served as reference samples. Three barcoding loci, namely ITS, rbcL, and matK, were used for PCR amplification of the reference samples and commercial samples representing 10 different companies. PCR success rate, sequencing efficiency, occurrence of SNPs, and BLAST analysis were used to assess the potential of the barcoding loci in authenticating the traded samples of turmeric. The PCR and sequencing success of the loci rbcL and ITS were found to be 100%, whereas matK showed no amplification. ITS proved to be the ideal locus because it showed greater variability than rbcL in discriminating the Curcuma species. The presence of C. zedoaria could be detected in one of the samples whereas cassava starch, wheat, barley, and rye in other two samples although the label claimed nothing other than turmeric powder in the samples. Unlabeled materials in turmeric powder are considered as adulterants or fillers, added to increase the bulk weight and starch content of the commodity for economic gains. These adulterants pose potential health hazards to consumers who are allergic to these plants, lowering the product's medicinal value and belying the claim that the product is gluten free. The study proved DNA barcoding as an efficient tool for testing the integrity and the authenticity of commercial products of turmeric.

    Full text: The spices Turmeric (curcuma longa) and Saffron (crocus sativus) have also been used as pigments. The EPR spectrum of each shows a readily detectable free radical signal. EPR spectra of the available pure chief active colorants in solid form also give free radical signals. Curcumin (turmeric) is a 'linear' symmetric phenolic, so is expected to do so. The peptide turmerin (commercially unavailable), containing sulphur, may also contribute to the ESR signal. Crocetin (saffron) is a 'linear' molecule, related to the beta-carotenes, which do not give free radical signals: but it does, presumably because of its particular resonant structure properties

    Full Text Available A forty-three year old house-wife developed dermatitis over the center of forehead following application of kumkum, bindi and sticker (except one brand since six months. Patch testing with various brands of kumkum and regularly available sticker used by the patient elicited positive reaction except one brand used by the patient. Kumkum is made by mixing turmeric (Curcuma longa powder with small amount of lime (calcium hydroxide. She was patch tested with turmeric, to which she developed positive reaction. Subsequently she was patch tested with turmeric powder boiled and air-dried and also the acetone-extract and precipitate of the powder. She tested positive to all the extracts and precipitates, but the turmeric powder which was dried by boiling did not elicit positive reaction. She was advised to use boiled and dried turmeric to make kumkum for use. However, the kumkum powder prepared following boiling had lost its adhesive property and hence was unacceptable. She was offered Castellani′s paint and eosin with starch for application. Both were acceptable for 2 months, but she subsequently developed irritant reaction to the paint with starch. She continues to use the non-allergic sticker (Kanchan sticker kumkum while we are trying to find other alternatives to kumkum.

    The impact of a natural supplement (Kepar; Rikrea, Italy), containing several plant extracts such as curcuma longa, silymarin, guggul, chlorogenic acid, and inulin, was evaluated in 78 patients with metabolic syndrome (MetS; 45 men; age: 62 ± 9 years). Kepar at a dose of 2 pills/d was given for 4 months as add-on therapy to the ongoing treatment, maintained at fixed doses for the entire study. Anthropometric variables, plasma lipids, glucose parameters, and oxidative stress were measured at baseline and after 4 months. We found significant reductions in body weight (from 81.1 ± 13.5 to 79.4 ± 12.5 kg, P < .0001), body mass index (from 29.6 [23.7] to 29.3 [21.9] kg/m(2), P = .001), and waist circumference (from 105 ± 11 to 102 ± 10 cm, P = .0004) as well as in fasting glucose (from 6.5 [11.7] to 6.4 [7.6] mmol/L, P = .014) and total cholesterol (from 4.8 ± 1.4 to 4.5 ± 1.0 mmol/L, P = .03). No significant changes were found in the other appraised parameters, including oxidative stress. In conclusion, after few months of treatment Kepar seems to exert beneficial effects in patients with MetS. Larger studies with a longer follow-up period are needed to confirm these preliminary findings. © The Author(s) 2015.

    Turmeric rhizome is a traditional herbal medicine, which has been widely used as a remedy to stop bleeding on fresh cuts and for wound healing by the rural and tribal population of India. To validate scientific and therapeutic application of turmeric rhizomes to stop bleeding on fresh cuts and its role in wound healing process. The water extracts of thoroughly scrubbed and washed turmeric rhizomes viz., Curcuma aromatica Salisb., Curcuma longa L., Curcuma caesia Roxb., Curcuma amada Roxb. and Curcuma zedoria (Christm.) Roscoe. were subjected to salting out and dialysis. The dialyzed crude enzyme fractions (CEFs) were assessed for proteolytic activity using casein as substrate and were also confirmed by caseinolytic zymography. Its coagulant activity and fibrinogenolytic activity were assessed using human citrated plasma and fibrinogen, respectively. The type of protease(s) in CEFs was confirmed by inhibition studies using specific protease inhibitors. The CEFs of C. aromatica, C. longa and C. caesia showed 1.89, 1.21 and 1.07 folds higher proteolytic activity, respectively, compared to papain. In contrast to these, C. amada and C. zedoria exhibited moderate proteolytic activity. CEFs showed low proteolytic activities compared to trypsin. The proteolytic activities of CEFs were confirmed by caseinolytic zymography. The CEFs of C. aromatica, C. longa and C. caesia showed complete hydrolysis of Aα, Bβ and γ subunits of human fibrinogen, while C. amada and C. zedoria showed partial hydrolysis. The CEFs viz., C. aromatica, C. longa, C. caesia, C. amada and C. zedoria exhibited strong procoagulant activity by reducing the human plasma clotting time from 172s (Control) to 66s, 84s 88s, 78s and 90s, respectively. The proteolytic activity of C. aromatica, C. longa, C. caesia and C. amada was inhibited (>82%) by PMSF, suggesting the possible presence of a serine protease(s). However, C. zedoria showed significant inhibition (60%) against IAA and moderate inhibition (30

    Herbs with "blood-activating" properties by traditional medicine theory often raise concerns for their possible anti-platelet or anticoagulation effects based on reports from in vitro studies. Such herbs have been implicated for bleeding manifestations based on only anecdotal reports. In particular, the combination of such herbs with anti-platelet agents is often empirically advised against despite lack of good clinical evidence. Here we studied 3 commonly used herbal preparations Curcuma longa, Angelica sinensis and Panax ginseng on their respective anti-platelet and anticoagulation effect, alone and in combination with aspirin. This is a randomized, double-blind, placebo-controlled trial involving 25 healthy volunteers for each herbal preparation. Each subject underwent 3 phases comprising of herbal product alone, aspirin alone and aspirin with herbal product, where each phase lasted for 3 weeks with 2 weeks of washout between phases. PT/APTT, platelet function by light transmission aggregometry and thrombin generation assay by calibrated automated thrombogram were measured at baseline and after each phase. Information on adverse reaction including bleeding manifestations was collected after each phase. On the whole there was no clinically relevant impact on platelet and coagulation function. With the exception of 5 of 24 subjects in the Curcuma longa group, 2 of 24 subjects in the Angelica sinensis group and 1 of 23 subjects in the Panax ginseng group who had an inhibition in arachidonic-acid induced platelet aggregation, there was no effect of these 3 herbals products on platelet aggregation by other agonists. Combination of these herbal products with aspirin respectively did not further aggravate platelet inhibition caused by aspirin. None of the herbs impaired PT/APTT or thrombin generation. There was no significant bleeding manifestation. This study on healthy volunteers provides good evidence on the lack of bleeding risks of Curcuma longa, Angelica sinensis

    Turmeric, the rhizome of Curcuma longa L., has a wide range of effects on human health. Turmeric oleoresin, an extract of turmeric, is often used for flavoring and coloring. Curcuminoids and turmeric essential oil are both contained in turmeric oleoresin, and both of these fractions have hypoglycemic effects. In the present study, we comprehensively assessed the effect of turmeric oleoresin on hepatic gene expression in obese diabetic KK-Ay mice using DNA microarray analysis and quantitative real-time polymerase chain reaction (PCR). Female KK-Ay mice aged 6 weeks (n = 6/group) were fed a high-fat diet containing turmeric oleoresin, curcuminoids, and essential oil for 5 weeks. The same diet without any of these fractions was used as a control diet. Ingestion of turmeric oleoresin and essential oil inhibited the development of increased blood glucose and abdominal fat mass, while curcuminoids only inhibited the increase in blood glucose. DNA microarray analysis indicated that turmeric oleoresin ingestion up-regulated the expression of genes related to glycolysis, beta-oxidation, and cholesterol metabolism in the liver of KK-Ay mice, while expression of gluconeogenesis-related genes was down-regulated. Real-time PCR analysis was conducted to assess the contribution of the curcuminoids and essential oil in turmeric oleoresin to the changes in expression of representative genes selected by DNA microarray analysis. This analysis suggested that curcuminoids regulated turmeric oleoresin ingestion-induced expression of glycolysis-related genes and also that curcuminoids and turmeric essential oil acted synergistically to regulate the peroxisomal beta-oxidation-related gene expression induced by turmeric oleoresin ingestion. These changes in gene expression were considered to be the mechanism by which the turmeric oleoresin affected the control of both blood glucose levels and abdominal adipose tissue masses. All of these results suggest that the use of whole turmeric

    The aim was to evaluate the activity of seven medicinal, anti-inflammatory plants at the hH 4 R with focus on defined chemical compounds from Curcuma longa. Activities were analyzed with membrane preparations from Sf9 cells, transiently expressing the hH 4 R, G αi2 and G β1γ2 subunits. From the methanolic extract of C. longa curcumin (1), demethoxycurcumin (2) and bis(4-hydroxy-cinnamoyl)methane (3) were isolated, purified with HPLC (elution-time 10.20, 9.66, 9.20 min, respectively) and together with six additional extracts, were characterized via radioligand binding studies at the hH 4 R. Compounds from C. longa were the most potent ligands at the hH 4 R. They exhibited estimated K i values of 4.26-6.26 µM (1.57-2.31 µg/mL) (1); 6.66--8.97 µM (2.26-3.04 µg/mL) (2) and 10.24-14.57 µM (3.16-4.49 µg/mL) (3) (95% CI). The estimated K i value of the crude extract of curcuma was 0.50-0.81 µg/mL. Fractionated curcumin and the crude extract surpassed the effect of pure curcumin with a K i value of 5.54 µM or 2.04 µg/mL [95% CI (4.47-6.86 µM), (1.65-2.53 µg/mL)]. Within this study, defined compounds of C. longa were recognized as potential ligands and reasonable lead structures at the hH 4 R. The mode of anti-inflammatory action of curcumin was further elucidated and the role of extracts in traditional phytomedicine was strengthened.

    Full Text Available A portable Near Infrared Reflectance Spectroscopy (NIRS instrument was applied to 40 growing rabbits to determine body and tissue differences induced by experimental factors. The rabbits were examined at 2 live sites, in 7 warm carcass tissues and in longissimus dorsi muscle samples prepared in ethanol. For this purpose, the method was applied in a bi-factorial experiment concerning the dietary oil source (O (maize vs. palm oil and Curcuma longa (C supplementation (0 and 3 g/kg, respectively. Significant chemical differences emerged for palmitic, oleic and linoleic acids in the longissimus dorsi muscle due to the O factor and for linolenic acid due to the C factor. The NIRS spectra and chemical analyses were elaborated by the Partial Least Squares (PLS method, and the rsquares in cross-validation (R2cv were retained as measure of the unoriented differentiation between the levels of the planned factor for each landmark and fatty acid (FA profile. Multivariate PLS analysis of the FA muscular fat showed that the O factor induced strong differentiation (R2cv: 0.96, while less influence (0.33 was observed for the C factor. The model based on the NIRS radiation of the landmarks clearly shows the O factor effects, not only in the perirenal (0.90 and scapular (0.85 fats, but also in the belly (0.76, liver (0.73 and hind legs (0.72. Whereas the C effects were only expressed in the live animals (ears: 0.66 and abdominal wall: 0.58 and in post-mortem (liver: 0.60. It was concluded that a preliminary NIRS scan of the carcass and of live rabbits can point out the presence of intrinsic experimental effects concerning the lipid metabolism of polyunsaturated FA of the n-6 series (O factor and n-3 series (C factor.

    Chronic hyperglycemia in diabetes leads to the overproduction of free radicals and the evidence is increasing because these radicals are responsible for the development of diabetic nephropathy. Diabetic nephropathy is an important microvascular complication and one of the main causes of end stage renal disease. The aim of the present study was to test the hypothesis that combined treatment with Nigella sativa (NS) and Curcuma longa (CL) is more effective than each of them alone in improving renal function and oxidative stress in alloxan-induced diabetic rats.Diabetes was induced in male albino rats with a single intravenous injection of alloxan (150 mg/kg). Two weeks after alloxan injection, rats were divided into five groups; control, diabetic and diabetic rats received either NS (10ml/kg/day), or CL (80mg/kg/day) and their combination by gastric intubation for 4 weeks.Diabetic rats exhibited many symptoms including loss of body weight, hyperglycemia, polyuria, renal enlargement and renal dysfunction. Significant increase in TBARS (lipid peroxidation marker) was observed in diabetic kidney. This was accompanied by a significant decrease in GSH content, SOD and CAT activities in the kidneys. Daily oral ingestion of NS and/or CL extract for 4 weeks has attenuated the oxidative stress in the kidney and reversed the adverse effect of diabetes in rats by lowering blood glucose levels, increased plasma insulin and restored body weight loss and renal function.These results confirm the role of oxidative stress in the development of diabetic nephropathy and point to the possible anti-oxidative mechanism being responsible for the nephroprotective action of NS and CL.

    Background In the present investigation, the effect of Curcuma longa (Cl) and Ocimum sanctum (Os) on myocardial apoptosis and cardiac function was studied in an ischemia and reperfusion (I-R) model of myocardial injury. Methods Wistar albino rats were divided into four groups and orally fed saline once daily (sham, control IR) or Cl (100 mg/kg; Cl-IR) or Os (75 mg/kg; Os-IR) respectively for 1 month. On the 31st day, in the rats of the control IR, Cl-IR and Os-IR groups LAD occlusion was undertaken for 45 min, and reperfusion was allowed for 1 h. The hemodynamic parameters{mean arterial pressure (MAP), heart rate (HR), left ventricular end-diastolic pressure (LVEDP), left ventricular peak positive (+) LVdP/dt (rate of pressure development) and negative (-) LVdP/dt (rate of pressure decline)} were monitored at pre-set points throughout the experimental duration and subsequently, the animals were sacrificed for immunohistopathological (Bax, Bcl-2 protein expression & TUNEL positivity) and histopathological studies. Results Chronic treatment with Cl significantly reduced TUNEL positivity (p < 0.05), Bax protein (p < 0.001) and upregulated Bcl-2 (p < 0.001) expression in comparison to control IR group. In addition, Cl demonstrated mitigating effects on several myocardial injury induced hemodynamic {(+)LVdP/dt, (-) LVdP/dt & LVEDP} and histopathological perturbations. Chronic Os treatment resulted in modest modulation of the hemodynamic alterations (MAP, LVEDP) but failed to demonstrate any significant antiapoptotic effects and prevent the histopathological alterations as compared to control IR group. Conclusion In the present study, significant cardioprotection and functional recovery demonstrated by Cl may be attributed to its anti-apoptotic property. In contrast to Os, Cl may attenuate cell death due to apoptosis and prevent the impairment of cardiac performance. PMID:16504000

    Long term exposure to dexamethasone (Dx) is associated with brain damage especially in the hippocampus via the oxidative stress pathway. Previously, an ethanolic extract from Curcuma longa Linn. (CL) containing the curcumin constituent has been reported to produce antioxidant effects. However, its neuroprotective property on brain histology has remained unexplored. This study has examined the effects of a CL extract on the densities of cresyl violet positive neurons and glial fibrillary acidic protein immunoreactive (GFAP-ir) astrocytes in the hippocampus of Dx treated male rats. It showed that 21 days of Dx treatment (0.5mg/kg, i.p. once daily) significantly reduced the densities of cresyl violet positive neurons in the sub-areas CA1, CA3 and the dentate gyrus, but not in the CA2 area. However, CL pretreatment (100mg/kg, p.o.) was found to significantly restore neuronal densities in the CA1 and dentate gyrus. In addition, Dx treatment also significantly decreased the densities of the GFAP-ir astrocytes in the sub-areas CA1, CA3 and the dentate gyrus. However, CL pretreatment (100mg/kg, p.o.) failed to protect the loss of astrocytes in these sub-areas. These findings confirm the neuroprotective effects of the CL extract and indicate that the cause of astrocyte loss might be partially reduced by a non-oxidative mechanism. Moreover, the detection of neuronal and glial densities was suitable method to study brain damage and the effects of treatment. Copyright © 2014 Elsevier GmbH. All rights reserved.

    The epidermal growth factor receptors (EGFRs) are significant targets for screening active compounds. In this work, an analytical method was established for rapid screening, separation, and identification of EGFRs antagonists from Curcuma longa. Human embryonic kidney 293 cells with a steadily high expression of EGFRs were used to prepare the cell membrane stationary phase in a cell membrane chromatography model for screening active compounds. Separation and identification of the retention chromatographic peaks was achieved by HPLC-MS. The active sites, docking extents and inhibitory effects of the active compounds were also demonstrated. The screening result found that ar-turmerone, curcumin, demethoxycurcumin, and bisdemethoxycurcumin from Curcuma longa could be active components in a similar manner to gefitinib. Biological trials showed that all of four compounds can inhibit EGFRs protein secretion and cell growth in a dose-dependent manner, and downregulate the phosphorylation of EGFRs. This analytical method demonstrated fast and effective characteristics for screening, separation and identification of the active compounds from a complex system and should be useful for drug discovery with natural medicinal herbs. © 2013 WILEY-VCH Verlag GmbH & Co.

    Kiom-18 is a novel composition of Cinnamomum cassia, Pinus densiflora, Curcuma longa and Glycyrrhiza glabra. Curcuma longa and Glycyrrhiza glabra, which are traditional medicines in Asia, have been reported to demonstrate preventive effects against atherosclerosis; however, they have not yet been developed into functional atherosclerosis treatments. We therefore studied the anti-atherosclerotic effects and possible molecular mechanisms of Kiom-18 using vascular smooth muscle cells (VSMCs). To assess the anti-proliferative effect of Kiom-18 in vitro, we performed thymidine incorporation, cell cycle progression, immunoblotting and immunofluorescence assays in VSMCs stimulated by platelet derived-growth factor (PDGF)-BB. In addition, we used LDLr knockout mice to identify the effects of Kiom-18 as a preliminary result in an atherosclerosis animal model. Kiom-18 inhibited platelet-derived growth factor (PDGF)-BB-stimulated-VSMC proliferation and DNA synthesis. Additionally, Kiom-18 arrested the cell cycle transition of G0/G1 stimulated by PDGF-BB and its cell cycle-related proteins. Correspondingly, the level of p27(kip1) expression was upregulated in the presence of the Kiom-18 extract. Moreover, in an atherosclerosis animal model of LDLr knockout mice, Kiom-18 extract showed a preventive effect for the formation of atherosclerotic plaque and suppressed body weight, fat weight, food treatment efficiency, neutrophil count, and triglyceride level. These results indicate that Kiom-18 exerts anti-atherosclerotic effects by inhibiting VSMC proliferation via G0/G1 arrest, which upregulates p27(Kip1) expression.

    Plant polyphenols may exert beneficial action against obesity-related oxidative stress and inflammation which promote insulin resistance. This study evaluated the effect of polyphenols extracted from French Curcuma longa on 3T3-L1 adipose cells exposed to H2 O2 -mediated oxidative stress. We found that Curcuma longa extract exhibited high amounts of curcuminoids identified as curcumin, demethoxycurcumin, and bisdemethoxycurcumin, which exerted free radical-scavenging activities. Curcuma longa polyphenols improved insulin-mediated lipid accumulation and upregulated peroxisome proliferator-activated receptor-gamma gene expression and adiponectin secretion which decreased in H2 O2 -treated cells. Curcuminoids attenuated H2 O2 -enhanced production of pro-inflammatory molecules such as interleukin-6, tumor necrosis factor-alpha, monocyte chemoattractant protein-1, and nuclear factor κappa B. Moreover, they reduced intracellular levels of reactive oxygen species elevated by H2 O2 and modulated the expression of genes encoding superoxide dismutase and catalase antioxidant enzymes. Collectively, these findings highlight that Curcuma longa polyphenols protect adipose cells against oxidative stress and may improve obesity-related metabolic disorders. © 2016 BioFactors, 42(4):418-430, 2016. © 2016 International Union of Biochemistry and Molecular Biology.

    Curcuma longa is the scientific name of Turmeric, which can be found on spice racks worldwide. This herb is responsible for the yellow coloring of many Currie dishes. Female albino rats were treated with oral administration of curcumin for 14 days before γ-irradiation. γ Radiation was applied in 0.1, 0.75 and 2 Gy, 1 hour after the last dose of curcuma administration. Animals were divided into control and 6 treated groups, all were irradiated with γ-rays, only three were injected with curcumin. Blood collected 1 and 48 hours after irradiation. Serum total protein, albumin, globulins, cholesterol, triglycerides, SGOT and SGPT were determined.Curcuma was found to elevate the protein profile (total protein, albumin and globulin) and ameliorates the hyperlipidaemic effects of γ- radiation. Curcuma also improved the liver functions affected by γ- irradiation.The experiment concluded that curcuma can be used as a radioprotector for occupationally exposed individuals to low doses and low dose rates.

    A simple, fast and efficient non-aqueous capillary electrophoresis method (NACE) was developed for the simultaneous determination of three major bioactive curcuminoids (CMNs) in Curcuma longa rhizomes and its herbal products. Good separation, resolution and reproducibility were achieved with the background electrolyte (BGE) consisting a mixture of 15.0 mM sodium tetraborate and 7.4 mM sodium hydroxide (NaOH) in 2:10:15 (v/v/v) of water, 1-propanol, and methanol. The influences of background electrolyte, sodium hydroxide, water, sodium dodecyl sulfate and hydroxylpropyl-β-cyclodextrin on separations were investigated. The separation was carried out in a fused-silica capillary tube with reverse polarity. Hydrodynamic injection of 25mbar for 12s was used for injecting samples and a voltage of 28 kV was applied for separation. The ultrasonication method was used for the extraction of CMNs from the turmeric herbal products and the extract was filtered and directly injected without any further treatments. The limits of detection and quantification were less than 5.0 and 14.6 µg/ml respectively for all CMNs. The percentage recoveries for CMNs were >97.2% (%RSD, <2.62). The results obtained by the method were compared with existing spectrophotometric and HPLC methods. The related compounds in the extract did not interfere in the determination of CMNs. The proposed NACE method is better than existing chromatographic and electrophoretic methods in terms of simple electrophoretic medium, fast analysis and good resolution.

    Although much has been published about curcumin, which is obtained from turmeric, comparatively little is known about turmeric itself. Turmeric, a golden spice obtained from the rhizome of the plant Curcuma longa, has been used to give color and taste to food preparations since ancient times. Traditionally, this spice has been used in Ayurveda and folk medicine for the treatment of such ailments as gynecological problems, gastric problems, hepatic disorders, infectious diseases, and blood disorders. Modern science has provided the scientific basis for the use of turmeric against such disorders. Various chemical constituents have been isolated from this spice, including polyphenols, sesquiterpenes, diterpenes, triterpenoids, sterols, and alkaloids. Curcumin, which constitutes 2-5% of turmeric, is perhaps the most-studied component. Although some of the activities of turmeric can be mimicked by curcumin, other activities are curcumin-independent. Cell-based studies have demonstrated the potential of turmeric as an antimicrobial, insecticidal, larvicidal, antimutagenic, radioprotector, and anticancer agent. Numerous animal studies have shown the potential of this spice against proinflammatory diseases, cancer, neurodegenerative diseases, depression, diabetes, obesity, and atherosclerosis. At the molecular level, this spice has been shown to modulate numerous cell-signaling pathways. In clinical trials, turmeric has shown efficacy against numerous human ailments including lupus nephritis, cancer, diabetes, irritable bowel syndrome, acne, and fibrosis. Thus, a spice originally common in the kitchen is now exhibiting activities in the clinic. In this review, we discuss the chemical constituents of turmeric, its biological activities, its molecular targets, and its potential in the clinic. © 2012 WILEY-VCH Verlag GmbH & Co.

    The potential for the transfer of active principle(s) of turmeric (Curcuma longa L.) and curcumin (major pigment in turmeric) via translactational route and its modulatory influence on the hepatic biotransformation system enzymes in the lactating dams and their suckling offspring was assessed. Turmeric (4 g/kg b.w. per day) and curcumin (0.4 g/kg b.w. per day) induced significant (P curcumin (0.2 g/kg b.w. per day) could modulate hepatic GST activity (P curcumin (0.4 g/kg b.w.). The induction in hepatic biotransformation system enzymes in lactating dams and F1 progeny suggests the passage of active constituents and/or metabolites of turmeric and curcumin via the translactational route.

    Curcuma longa rhizome is used extensively in culinary preparations in Far East and South-East Asia. Health benefits of curcuminoids from C. longa as antioxidants, anti-cancer and anti-inflammatory molecules have been well documented. We report here for the first time that Bisdemethoxycurcumin (BDMC) from C. longa, acts as an inhibitor to inactivate human pancreatic α-amylase, a therapeutic target for oral hypoglycemic agents in type-2 diabetes. Bioactivity guided isolation of rhizome isopropanol extract led to the identification by HPLC and NMR of BDMC as a lead small molecule inhibitor of porcine and human pancreatic α-amylase with an IC(50) value of 0.026 and 0.025 mM, respectively. Kinetic analysis revealed that using starch as the substrate, HPA exhibited an uncompetitive mode of inhibition with an apparent K(i) of 3.0 μM. The study gains importance as BDMC could be a good drug candidate in development of new inhibitors of HPA and of functional foods for controlling starch digestion in order to reduce post-prandial hyperglycemia.

    The present study was designed to identify the chemical constituents of the methanolic extract of Curcuma longa L. rhizomes and their inhibitory effect on a hepatoma cell line. The methanolic extract was subjected to GC-MS analysis to identify the volatile constituents and the other part of the same extract was subjected to liquid column chromatographic separation to isolate curcumin. The inhibition of cell growth in the hepatoma cell line and the cytopathological changes were studied. GC-MS analysis showed the presence of fifty compounds in the methanolic extract of C. longa. The major compounds were ar-turmerone (20.50 %), β-sesquiphellandrene (5.20 %) and curcumenol (5.11 %). Curcumin was identified using IR, 1H and 13C NMR. The inhibition of cell growth by curcumin (IC50 = 41.69 ± 2.87 μg mL-1) was much more effective than that of methanolic extract (IC50 = 196.12 ± 5.25 μg mL-1). Degenerative and apoptotic changes were more evident in curcumin- treated hepatoma cells than in those treated with the methanol extract. Antitumor potential of the methanolic extract may be attributed to the presence of sesquiterpenes and phenolic constituents including curcumin (0.051 %, 511.39 μg g-1 dried methanol extract) in C. longa rhizomes.

    Full Text Available Turmeric (Curcuma longa L. is a vegetatively-propagated crop which is used as a natural dye in the food industryand also presents many biological active compounds. Turmeric conventional breeding is difficult and often limited to germplasmselection. The aim of this study was to evaluate the genetic divergence among turmeric accessions available in Brazil using sevenmorpho-agronomical descriptors. Overall genetic divergence was low, although some divergent genotypes were identified. Fourmain groups of genotypes were identified and could be further used in breeding programs. Canonical variable analysis suggestedthat some descriptors were more important to discriminate accessions and also that one of the descriptors could be discarded. Theresults provided useful insights for better management of the germplasm collection, optimizing conservational and breeding efforts.

    Extensive research within last two decades has indicated that curcumin extracted from turmeric (Curcuma longa), exhibits anticancer potential, in part through the modulation of inflammatory pathways. However, the residual antitumor activity of curcumin-free turmeric (CFT) relative to curcumin or turmeric is not well-understood. In the present study, therefore, we determined activities of these agents in both in vitro and in vivo models of human HCT-116 colorectal cancer (CRC). When examined in an in vitro antiproliferative, clonogenic or anti-inflammatory assay system, we found that curcumin was highly active whereas turmeric and CFT had relatively poor activity against CRC cells. However, when examined in vivo at an oral dose of either 100 or 500 mg/kg given to nude mice bearing CRC xenografts, all three preparations of curcumin, turmeric, and CFT similarly suppressed the growth of the xenograft. The effect of CFT on suppression of tumor growth was dose-dependent, with 500 mg/kg tending to be more effective than 100 mg/kg. Interestingly, 100 mg/kg curcumin or turmeric was found to be more effective than 500 mg/kg. When examined in vivo for the expression of biomarkers associated with cell survival (cIAP-1, Bcl-2, and survivin), proliferation (Ki-67 and cyclin D1) and metastasis (ICAM-1 and VEGF), all were down-modulated. These agents also suppressed inflammatory transcription factors (NF-κB and STAT3) in tumor cells. Overall, our results with CFT provide evidence that turmeric must contain additional bioactive compounds other than curcumin that, in contrast to curcumin, exhibit greater anticancer potential in vivo than in vitro against human CRC. Moreover, our study highlights the fact that the beneficial effects of turmeric and curcumin in humans may be more effectively realized at lower doses, whereas CFT could be given at higher doses without loss in favorable activity.

    A monodisperse molecularly imprinted polymer (MIP) for curcumin was first prepared by precipitation polymerization using methacrylamide (MAM) and 4-vinylpyridine as functional co-monomers, divinylbenzene as a crosslinker, and a mixture of acetonitrile and toluene as a porogen. The use of MAM as the co-monomer resulted in the formation of a monodisperse MIP and non-imprinted polymer (NIP). MIP and NIP, respectively, were monodispersed with a narrow particle size distribution (3.3 ± 0.09 and 3.5 ± 0.10 μm). In addition to shape recognition, hydrophobic and hydrogen-bonding interactions affected the retention and molecular-recognition of curcumin on the MIP. The MIP for curcumin could extract curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) in Curcuma longa L.

    The recruitment of arterial leukocytes to endothelial cells is an important step in the progression of various inflammatory diseases. Therefore, its modulation is thought to be a prospective target for the prevention or treatment of such diseases. Adhesion molecules on endothelial cells are induced by proinflammatory cytokines, including tumor necrosis factor-α (TNF-α), and contribute to the recruitment of leukocytes. In the present study, we investigated the effect of hot water extract of Curcuma longa (WEC) on the protein expression of adhesion molecules, monocyte adhesion induced by TNF-α in human umbilical vascular endothelial cells (HUVECs). Treatment of HUVECs with WEC significantly suppressed both TNF-α-induced protein expression of adhesion molecules and monocyte adhesion. WEC also suppressed phosphorylation and degradation of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha (IκBα) induced by TNF-α in HUVECs, suggesting that WEC inhibits the NF-κB signaling pathway.

    Curcuma longa has long been used in China and India as anti-inflammatory agent to treat a wide variety of conditions and also as a spice for varied curry preparations. The chemoprofile of the Curcuma species exhibits the presence of varied phytochemicals with curcumin being present in all three species but AA only being shown in C. longa . This study explored the effect of a curcumin/AA combination on human cancer cell lines. The curcumin/AA combination was assessed by isobologram analysis using the Loewe additivity drug interaction model. The drug combination showed additive cytotoxicity toward CCRF-CEM and CEM/ADR5000 leukemia cell lines and HCT116p53 +/+ and HCT116p53 -/- colon cancer cell line, while the glioblastoma cell lines U87MG and U87MG.ΔEGFR showed additive to supra-additive cytotoxicity. Gene expression profiles predicting sensitivity and resistance of tumor cells to induction by curcumin and AA were determined by microarray-based mRNA expressions, COMPARE, and hierarchical cluster analyses. Numerous genes involved in transcription ( TFAM, TCERG1, RGS13, C11orf31 ), apoptosis-regulation ( CRADD, CDK7, CDK19, CD81, TOM1 ) signal transduction ( NR1D2, HMGN1, ABCA1, DE4ND4B, TRIM27 ) DNA repair ( TOPBP1, RPA2 ), mRNA metabolism ( RBBP4, HNRNPR, SRSF4, NR2F2, PDK1, TGM2 ), and transporter genes ( ABCA1 ) correlated with cellular responsiveness to curcumin and ascorbic acid. In conclusion, this study shows the effect of the curcumin/AA combination and identifies several candidate genes that may regulate the response of varied cancer cells to curcumin and AA.

    The present study was designed to investigate the mineral content and antimicrobial activity of Curcuma Longa extracts and its essential oil. We also determined the lipid peroxidation inhibition activity of the ethanolic extract against sodium nitroprusside (SNP) induced thiobarbituric acid reactive species (TBARS) formation in rat's brain, kidney and liver homogenates. Major constituents of essential oil identified by gas chromatography and mass spectrometry (GCMS) were beta-sesquiphellandrene (38.69%), alpha-curcumene (18.44%) and p-mentha-1,4 (8)-diene (16.29%). Atomic absorption spectroscopy (AAS) was used for the quantitative estimation of Calcium (Ca), Magnesium (Mg), Iron (Fe), Copper (Cu), Zinc (Zn), Chromium (Cr), Nickel (Ni) and Manganese (Mn). The extract showed highest Mg (49.4 mg/l) concentration followed by Ca (35.42 mg/l) and Fe (1.27 mg/l). Our data revealed that the ethanolic extract of Curcuma Longa at 1-10 mg/kg significantly inhibited TBARS production in all tested homogenates. Crude extracts and essential oil were tested against three gram positive bacteria i.e. Bacillus subtilis, Bacillus atrophoeus, Staphylococcus aureus, six gram negative bacteria i.e. Escherichia coli, Klebsiella pneumonias, Salmonella typhi, Pseudomonas aeruginosa, Erwinia carotovora, Agrobacterium tumefaciens and one fungal strain namely Candida albicans by disc diffusion assay. Essential oil showed highest anti-microbial activity as compared to the crude extracts. The present study confirms the significant antimicrobial and antioxidant potential of the studied plant, which can be considered as a diet supplement for a variety of oxidative stress induced or infectious diseases.

    Full Text Available Introduction: Intestinal mucositis is a frequent limiting factor in anticancer therapy and there is currently no broadly effective treatment targeted to cure this side effect. Objective: This study aimed to evaluate the effects of a mucoadhesive formulation containing curcuminoids (MFC from Curcuma longa L. on the pathogenesis of 5-fluorouracil (5-FU-induced intestinal mucositis. Methods: Three intraperitoneal 5-FU injections (200 mg/kg were used to induce intestinal mucositis in adult Swiss male mice. Treatment was provided orally (MFC 3.75, 7.5 and 15 mg/kg, thirty minutes before 5-FU injections, daily until euthanasia. Duodenal samples were collected to perform morphometric and histopathological analysis, to investigate the expression of Ki-67, p53, Bax and Bcl-2 by immunohistochemistry, to evaluate neutrophil activity myeloperoxidase (MPO-mediated and oxidative stress by malondialdehyde (MDA determination. Mice body weight was assessed as well. Results: As expected, 5-FU induced a significant weight loss (∼17%, P < 0.001, shortening in villi height (∼55.4% and crypts depth (∼47%, and increased (∼64% the histological severity score when compared to other groups (P < 0.05. These pathological changes were markedly alleviated by the three MFC treatment doses (P < 0.05, in special with the dose MFC 15 mg/kg. This dose also stimulated cell proliferation by ∼90% in the epithelial cells lining from villi and crypts (P < 0.05, reduced MPO levels and MDA formation by 60% and 44%, respectively (P < 0.05. Conclusions: Our data suggest the therapeutic potential of the formulation for treating intestinal mucositis in mice. Supplementary studies are underway searching for the elucidation of mechanisms involved in the protective effects of MFC in order to make this formulation a clinical tool for mucositis treatment.

    Aqueous extract of C. longa when administered 4 h after induction of E. coli lipopolysaccharide-induced uveitis in rats showed significantly suppressed inflammation with a significantly lower mean clinical grade, histopathological grade and aqueous humor (AH) protein level compared to vehicle treated group. Although, prednisolone group showed significantly lower clinical grade, histopathological grades and AH protein levels compared to C. longa group, TNF-alpha levels did not differ significantly. Moreover, when the aqueous extract was administered starting from 3 days before induction of uveitis, the mean clinical and histopathological grade as well as AH protein and TNF-alpha levels were comparable to C. longa group when treatment was administered 4 h after induction of uveitis. It is concluded that topically applied standardized aqueous extract of C. longa suppresses endotoxin-induced uveitis in rats by reducing TNF-alpha activity.

    Curcuminoids possess powerful antioxidant activity as demonstrated in many chemical in vitro tests and in several in vivo trials. Nevertheless, the mechanism of this activity is not completely elucidated and studies on the in vivo antioxidant effects are still needed. Metabolomics may be used as an attractive approach for such studies and in this paper, we describe the effects of oral administration of a Curcuma longa L. extract (150 mg/kg of total curcuminoids) to 12 healthy rats with particular attention to urinary markers of oxidative stress. The experiment was carried out over 33 days and changes in the 24-h urine samples metabolome were evaluated by (1)H NMR and HPLC-MS. Both techniques produced similar representations for the collected samples confirming our previous study. Modifications of the urinary metabolome lead to the observation of different variables proving the complementarity of (1)H NMR and HPLC-MS for metabolomic purposes. The urinary levels of allantoin, m-tyrosine, 8-hydroxy-2'-deoxyguanosine, and nitrotyrosine were decreased in the treated group thus supporting an in vivo antioxidant effect of the oral administration of Curcuma extract to healthy rats. On the other hand, urinary TMAO levels were higher in the treated compared to the control group suggesting a role of curcumin supplementation on microbiota or on TMAO urinary excretion. Furthermore, the urinary levels of the sulphur containing compounds taurine and cystine were also changed suggesting a role for such constituents in the biochemical pathways involved in Curcuma extract bioactivity and indicating the need for further investigation on the complex role of antioxidant curcumin effects.

    Background Even though Curcuma longa L. possesses various biological activities, it has strong flavor and taste, which decrease consumer palatability and limit industrial applications in food. Objective The present study investigates the effects of C. longa L. fermented with Aspergillus oryzae supplementation in 60% high-fat diet-induced obese rats measured by the activation of adipogenesis and lipolysis. Design Rats were divided into four groups (n=6 per group) after 1 week of acclimatization: a normal diet group comprised rats fed the AIN76A rodent diet; a high-fat diet-induced obese group with rats fed a 60% high-fat diet; a Garcinia cambogia treated group (positive control) with rats fed a 60% high-fat diet with G. cambogia 500 g/kg body weight (b.w.)/day; and an fermented C. longa L. 50% ethanolic extract treated group (FCE50) with rats fed a 60% high-fat diet with FCE50 500 g/kg b.w./day. Each group received the appropriate vehicle or sample daily by gastric intubation for 12 weeks. Results We found that FCE50 administration suppressed b.w. gain and reduced white adipose tissue weight, serum triglyceride (TG), and cholesterol in high-fat diet-induced obese rats. These results can be associated with the suppression of adipocyte differentiation and lipogenesis with a decrease in the mRNA expressions of fatty acid synthase, acetyl-CoA carboxylase, adipocyte protein 2, and lipoprotein lipase induced by FCE50 administration. In addition, FCE50 increased lipolysis and β-oxidation by up-regulating the expression of lipases such as adipose triglyceride lipase, hormone-sensitive lipase, adiponectin, and AMP-activated protein kinase. Conclusions These results suggest that FCE50 can be a candidate for the prevention of obesity via suppressing adipogenesis and promoting lipolysis. PMID:26822962

    The medicinal plants Artemisia iwayomogi and Curcuma longa radix are both used to treat hyperlipidemia in traditional Korean and Chinese medicine. To evaluate the anti-hyperlipidemic effects of the 30% ethanol extracts of A. iwayomogi (AI), C. longa (CL), and the mixture of A. iwayomogi and C. longa (ACE), using a high-fat diet-induced hyperlipidemia model. Six of seven groups of C57BL/6N male mice (i.e., not including the naïve group) were fed a high-fat diet freely for 10 weeks. Of these six groups, five (i.e., not including the control group) were administered a high-fat diet supplemented with AI (100mg/kg), CL (100mg/kg), ACE (50 or 100mg/kg), or Lipitor (20mg/kg). Serum lipid profiles, obesity-related markers, hepatic steatosis, hepatic gene expression, and oxidative stress markers were analyzed. AI, CL, and ACE were associated with significant effects on serum lipid profiles (total cholesterol [TC] and triglyceride), body, liver and peritoneal adipose tissue weights, hepatic lipid accumulation, and oxidative stress biomarkers. ACE at 100mg/kg was associated with significantly greater improvements in serum TC and triglyceride, hepatic triglyceride, epididymal adipocyte size, and oxidative stress biomarkers, compared with AI and CL. AI, CL and ACE normalized lipid synthesis-associated gene expression (peroxisome proliferator-activated receptor gamma, fatty acid synthase, sterol regulatory element-binding transcription factor-1c, and peroxisome proliferator-activated receptor alpha). ACE exhibits anti-hyperlipidemia properties and is associated with partially synergistic effects compared with AI or CL alone. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The purpose of the study was to investigate the protective effect of the Curcuma longa L. extract (CLE) and its curcuminoids against blue light-induced cytotoxicity in human retinal pigment epithelial (RPE) cells laded with A2E. A2E has been concerned in age-related macular degeneration (AMD). To perform this study, A2E-accumulated ARPE-19 cells were exposed to blue light to induce cytotoxicity. The cytotoxicity and apoptotic gene expression levels were evaluated using a lactate dehydrogenase (LDH) assay and real-time PCR analysis, respectively. Curcuma longa L. extract was found to exert a protective effect in a dose-dependent manner. At a concentration of 15 μm, curcumin, demethoxycurcumin and bisdemethoxycurcumin exerted significant protective effects against blue light-induced cytotoxicity. Treatment with CLE and curcuminoids meaningfully reduced the mRNA levels of c-Abl and p53, which was known to be augmented in apoptotic RPE cells. Demethoxycurcumin and bisdemethoxycurcumin were found to inhibit p38 expression, which is increased in blue light-irradiated A2E-accumulated RPE cells. Curcuma longa L. extract and its curcuminoids provided significant protection against photooxidative damage and apoptosis in the RPE cells. Our results suggest that curcuminoids may show potential in the treatment of AMD. © 2017 Royal Pharmaceutical Society.

    Turmeric is one of the prominently use herbal plants due to its diverse beneficial effects especially in Indian medicine. The rhizome part of the turmeric contains valuable compounds which have been said to owe its antimicrobial effects, anti-cancer, anti-inflammatory and enhance wound healing. Due to its short-life span and perishable properties, the conversion of the rhizome into turmeric extract is desirable. Several methods have been used for extraction such as Soxhlet extraction and pressurized liquid extraction (PLE). However, these techniques are tedious, laborious, time consuming and involves the usage of toxic organic solvent, of which safeness of the end product is doubtful. In this study, a rapid, reliable and green extraction method of supercritical fluid extraction (SFE) and ultrasonic assisted extraction (UAE) were used. SFE without modifier has resulted in 0.0006 mg/ 100 g of curcuminoids concentration and 5.62 % of yield (dry weight basis). UAE using ethanol was able to produce significantly the highest yield (6.40 %, dry weight basis) and the highest curcuminoids concentration (0.1020 mg/ 100 g). However, SFE was able to produce extract that contain significantly higher major volatile compounds; tumerone, ar-turmerone and curlone. Therefore, this study proves that both extraction methods were able to produce high quality turmeric extract. (author)

    In the traditional system of medicine, Ayurveda, several spices and herbs are thought to possess medicinal properties. Among the spices, turmeric rhizomes (Curcuma longa. Linn.) are used as flavoring and coloring agents in the Indian diet everyday. In this research, we studied the effect of turmeric and its active principle, curcumin, on diabetes mellitus in a rat model. Alloxan was used to induce diabetes. Administration of turmeric or curcumin to diabetic rats reduced the blood sugar, Hb and glycosylated hemoglobin levels significantly. Turmeric and curcumin supplementation also reduced the oxidative stress encountered by the diabetic rats. This was demonstrated by the lower levels of TBARS (thiobarbituric acid reactive substances), which may have been due to the decreased influx of glucose into the polyol pathway leading to an increased NADPH/NADP ratio and elevated activity of the potent antioxdiant enzyme GPx. Moreover, the activity of SDH (sorbitol dehydrogenase), which catalyzes the conversion of sorbitol to fructose, was lowered significantly on treatment with turmeric or curcumin. These results also appeared to reveal that curcumin was more effective in attenuating diabetes mellitus related changes than turmeric.

    Full Text Available Introduction: Several studies towards the development of an effective treatment for intestinal mucositis have been reported, since this condition represents a major problem in clinical oncology practice due to cytotoxic effects of chemotherapy. However standardized protocols and universally accepted treatment options are yet to be established. Objectives: Given above, this study evaluated the protective effects of a mucoadhesive formulation containing both Bidens pilosa L. (Asteraceae (BP and curcuminoids from Curcuma longa L. (Zingiberaceae (CL on intestinal mucositis induced by 5-fluoruoacil (5-FU in mice. Results: As expected, animals only treated with 5-FU (200 mg/kg showed a significant reduction of 60.3 and 42.4% in villi and crypts size, respectively, when compared to control. On the other hand, the proposed therapeutic/prophylactic treatment with mucoadhesive formulations managed to reduce histopathologic changes in mice bearing mucositis, especially at 125 mg/kg BP + 15 mg/kg CL dose. The formulation promoted an increase of 275.5% and 148.7% for villi and crypts size, respectively. Moreover, chemotherapy-related weight loss was reduced by 7.4% following the treatment. In addition, an increase of 10 and 30.5% in red and white blood cells was observed when compared to 5-FU group. Furthermore, treatments with the mucoadhesive formulation containing BP/CL up modulated Ki-67 and Bcl-2 expression while reduced pro-apoptotic regulator Bax. The formulation also modulated inflammatory response triggered by 5-FU through reduction of 68% of myeloperoxidase activity and a 4-fold increase in anti-inflammatory IL-10 levels. In parallel, the oxidative stress via lipid peroxidation was reduced as indicated by decrease of 63% of malondialdehyde concentrations. Additionally, the new formulation presented low acute oral systemic toxicity, being classified in the category 5 (2000 mg/kg < LD50 < 5000 mg/kg of the Globally Harmonized

    Though the initial etiologies of arthritis are multifactorial, clinically, patients share the prime complaints of the disease, pain. Here the authors assessed the analgesic and anti-inflammatory effects of UP1304, a composite that contains a standardized blend of extracts from the rhizome of Curcuma longa and the root bark of Morus alba, on rats with carrageenan-induced paw edema. A plant library was screened for bradykinin receptor antagonists. In vivo, the anti-inflammatory and analgesic effects of the standardized composite, UP1304, were evaluated in rats with carrageenan-induced paw edema using oral dose ranges of 100-400 mg/kg. Ibuprofen, at a dose of 200 mg/kg, was used as a reference compound. In vitro, cyclooxygenase (COX) and lipoxygenase (LOX) inhibition assays were performed to evaluate the degree of inflammation. Statistically significant improvements in pain resistance and paw edema suppression were observed in animals treated with UP1304, when compared to vehicle-treated rats. Results from the highest dose of UP1304 (400 mg/kg) were similar to those achieved by ibuprofen treatment at 200 mg/kg. In vitro, UP1304 showed dose-dependent inhibition of the enzymatic activities of COX and LOX. A half-maximal inhibitory concentration of 9.6 μg/mL for bradykinin B1 inhibition was calculated for the organic extract of C. longa. Curcumin showed Ki values of 2.73 and 58 μg/mL for bradykinin receptors B1 and B2, respectively. Data presented here suggest that UP1304, analgesic and anti-inflammatory agent of botanical origin, acted as a bradykinin receptor B1 and B2 antagonist, and inhibited COX and LOX enzyme activities. This compound should be considered for the management of symptoms associated with arthritis.

    The purpose of this study was to investigate the activity of xanthorrhizol isolated from Curcuma xanthorrhiza Roxb. on Candida albicans biofilms at adherent, intermediate, and mature phase of growth. C. albicans biofilms were formed in flat-bottom 96-well microtiter plates. The biofilms of C. albicans at different phases of development were exposed to xanthorrhizol at different concentrations (0.5 µg/mL-256 µg/mL) for 24 h. The metabolic activity of cells within the biofilms was quantified using the XTT reduction assay. Sessile minimum inhibitory concentrations (SMICs) were determined at 50% and 80% reduction in the biofilm OD₄₉₀ compared to the control wells. The SMIC₅₀ and SMIC₈₀ of xanthorrhizol against 18 C. albicans biofilms were 4--16 µg/mL and 8--32 µg/mL, respectively. The results demonstrated that the activity of xanthorrhizol in reducing C. albicans biofilms OD₄₉₀ was dependent on the concentration and the phase of growth of biofilm. Xanthorrhizol at concentration of 8 µg/mL completely reduced in biofilm referring to XTT-colorimetric readings at adherent phase, whereas 32 µg/mL of xanthorrhizol reduced 87.95% and 67.48 % of biofilm referring to XTT-colorimetric readings at intermediate and mature phases, respectively. Xanthorrhizol displayed potent activity against C. albicans biofilms in vitro and therefore might have potential therapeutic implication for biofilm-associated candidal infections.

    Aging is a progressive process, and it may lead to the initiation of neurological diseases. In this study, we investigated the effects of wild Indian Curcuma longa using a Morris water maze paradigm on learning and spatial memory in adult and D-galactose-induced aged mice. In addition, the effects on cell proliferation and neuroblast differentiation were assessed by immunohistochemistry for Ki67 and doublecortin (DCX) respectively. The aging model in mice was induced through the subcutaneous administration of D-galactose (100 mg/kg) for 10 weeks. C. longa (300 mg/kg) or its vehicle (physiological saline) was administered orally to adult and D-galactose-treated mice for the last three weeks before sacrifice. The administration of C. longa significantly shortened the escape latency in both adult and D-galactose-induced aged mice and significantly ameliorated D-galactose-induced reduction of cell proliferation and neuroblast differentiation in the subgranular zone of hippocampal dentate gyrus. In addition, the administration of C. longa significantly increased the levels of phosphorylated CREB and brain-derived neurotrophic factor in the subgranular zone of dentate gyrus. These results indicate that C. longa mitigates D-galactose-induced cognitive impairment, associated with decreased cell proliferation and neuroblast differentiation, by activating CREB signaling in the hippocampal dentate gyrus.

    Sodium metabisulphite is used as an antioxidant agent in many pharmaceutical formulations. It is extensively used as a food preservative and disinfectant. It has been demonstrated that sulphite exposure can affect some organs. Curcumin, the main element of Curcuma longa, has been identified to have multiple protective properties. The present study extends the earlier works to quantitative evaluation of the effects of sulphite and curcumin on the heart structure using stereological methods. In this study, 28 rats were randomly divided into four experimental groups. The rats in groups I to IV received distilled water (group I), sodium metabisulphite (25 mg/ kg/day) (group II), curcumin (100 mg/kg/day) (group III), and sodium metabisulphite+curcumin (group IV), respectively, for 8 weeks. The left ventricle was subjected to stereological methods to estimate the quantitative parameters of the myocardium. A 20 % decrease was observed in the total volume of ventricular tissue in the sulphite-treated animals compared to the distilled water treatment (P curcumin did not protect the animals against the structural changes of the ventricle. Sulphite, as a preservative food agent, reduced the length and volume of the ventricular capillaries and curcumin could not protect them.

    Curcuma longa L. (CLL), a traditional herbal medicine, has been widely used for the prevention of diabetic vascular complications in recent years. However, the protective effects of curcuminoids in CLL on the AGEs-induced damage to mesangial cell are not fully understood. In this present study, dihydroethidium, superoxide dismutase kit, malondialdehyde kit, and acridine orange/ethidium bromide staining methods were used to evaluate the activities of curcumin and demethoxycurcumin (10(-11)-10(-9) M) on AGEs-induced oxidative stress and apoptosis, which were associated with the damage to mesangial cell. The results showed that these two compounds could significantly restore advanced glycation end products (AGEs)-induced apoptosis to normal levels (IC50 = 3.874 × 10(-11) M for curcumin and IC50 = 6.085 × 10(-11) M for demethoxycurcumin) and reduce remarkably reactive oxygen species generation in mesangial cell. Furthermore, curcumin and demethoxycurcumin dramatically elevated AGEs-decreased superoxide dismutase activity while significantly reducing AGEs-increased malondialdehyde content in cell culture supernatant. Our results suggest that both curcumin and demethoxycurcumin have a significant protective potential to the prevention of diabetic nephropathy. Georg Thieme Verlag KG Stuttgart · New York.

    Plant density was varied with P, Ca, Mg, and KNO3 in a multifactor experiment to improve Curcuma longa L. micropropagation, biomass and microrhizome development in fed-batch liquid culture. The experiment had two paired D-optimal designs, testing sucrose fed-batch and nutrient sucrose fed-batch techniques. When sucrose became depleted, volume was restored to 5% m/v sucrose in 200 ml of modified liquid MS medium by adding sucrose solutions. Similarly, nutrient sucrose fed-batch was restored to set points with double concentration of treatments’ macronutrient and MS micronutrient solutions, along with sucrose solutions. Changes in the amounts of water and sucrose supplementations were driven by the interaction of P and KNO3 concentrations. Increasing P from 1.25 to 6.25 mM increased both multiplication and biomass. The multiplication ratio was greatest in the nutrient sucrose fed-batch technique with the highest level of P, 6 buds/vessel, and the lowest level of Ca and KNO3. The highest density (18 buds/vessel) produced the highest fresh biomass at the highest concentrations of KNO3 and P with nutrient sucrose fed-batch, and moderate Ca and Mg concentrations. However, maximal rhizome dry biomass required highest P, sucrose fed-batch, and a moderate plant density. Different media formulations and fed-batch techniques were identified to maximize the propagation and storage organ responses. A single experimental design was used to optimize these dual purposes.

    The aim of the study was to assess the curcumin containing ethanolic extract (EtOH) obtained from Curcuma longa (Cl) against retardation of wound healing by aspirin. Wound healing process was retarded by administering the dose of 150 mg/kg body weight of aspirin orally for 9 days to observe the effect of EtOH obtained from Cl using excision and incision wound model in rats. The various parameters such as % wound contraction, epithelialization period, hydroxyproline, tensile strength were observed at variant time intervals and histopathological study was also performed. Curcumin containing 5% and 10% ethanolic extract ointment have shown significant (P < 0.01) wound healing activity against an aspirin (administered 150 mg/kg body weight orally for 9 days) retarded wound healing process. Topical application of ointment showed significant (P < 0.01) difference as compared to the control group. Histopathological studies also showed healing of the epidermis, increased collagen, fibroblasts and blood vessels. Ethanolic extract of Cl ointment (EtOHCl) containing 10% curcumin displayed remarkable healing process against wound retardation by aspirin.

  13. Effects of curcuminoids identified in rhizomes of Curcuma longa on BACE-1 inhibitory and behavioral activity and lifespan of Alzheimer’s disease Drosophila models

    Science.gov (United States)

    2014-01-01

    Background Alzheimer’s disease (AD) is the most common type of presenile and senile dementia. The human β-amyloid precursor cleavage enzyme (BACE-1) is a key enzyme responsible for amyloid plaque production, which implicates the progress and symptoms of AD. Here we assessed the anti-BACE-1 and behavioral activities of curcuminoids from rhizomes of Curcuma longa (Zingiberaceae), diarylalkyls curcumin (CCN), demethoxycurcumin (DMCCN), and bisdemethoxycurcumin (BDMCCN) against AD Drosophila melanogaster models. Methods Neuro-protective ability of the curcuminoids was assessed using Drosophila melanogaster model system overexpressing BACE-1 and its substrate APP in compound eyes and entire neurons. Feeding and climbing activity, lifespan, and morphostructural changes in fly eyes also were evaluated. Results BDMCCN has the strongest inhibitory activity toward BACE-1 with 17 μM IC50, which was 20 and 13 times lower than those of CCN and DMCCN respectively. Overexpression of APP/BACE-1 resulted in the progressive and measurable defects in morphology of eyes and locomotion. Remarkably, supplementing diet with either 1 mM BDMCCN or 1 mM CCN rescued APP/BACE1-expressing flies and kept them from developing both morphological and behavioral defects. Our results suggest that structural characteristics, such as degrees of saturation, types of carbon skeleton and functional group, and hydrophobicity appear to play a role in determining inhibitory potency of curcuminoids on BACE-1. Conclusion Further studies will warrant possible applications of curcuminoids as therapeutic BACE-1 blockers. PMID:24597901

    Full Text Available The goal of the present study was to evaluate the effect of turmeric ingestion on lipid peroxidation and GSH content, promoted by in vitro acetaminophen, on hepatocytes primary culture from well-nourished and malnourished rats. Four groups of Holtzman male rats were used: 1 WNG, well-nourished, fed lab chow diet ad libitum; 2 MNG, malnourished, fed 60% of the diet consumed by WNG; 3 WNG+T fed the same diet of WNG, but containing 1% of turmeric; 4 MNG+T fed 60% of the diet consumed by WNG+T. The animals were sacrificed at 90 days of age, the livers excised and hepatocytes primary cultures were prepared. Half of the plates of hepatocytes culture were treated with acetaminophen. Dose-response curve showed that 6 mM acetaminophen increased peroxidation around 54% and decreased GSH content around 63%. The model of malnutrition used, by restricting food ingestion (40%, decreased body weight in 33% and peroxidation index around 42% and increased GSH content around 43%. Turmeric ingestion decreased hepatocyte peroxidation in both well-nourished (42% and malnourished rats (33% and was able to avoid the acetaminophen pro-oxidant effect in both well-nourished and malnourished animals. Turmeric ingestion played a beneficial role to the organism and, therefore, can be considered a functional food.O objetivo do presente estudo foi avaliar o efeito da ingestão de cúrcuma sobre a peroxidação lipídica e conteúdo de GSH, por ação tóxica in vitro de paracetamol, utilizando cultura primária de hepatócitos.

    The essential oils of ginger (Zingiber officinale) and turmeric (Curcuma longa) contain a large variety of terpenoids, some of which possess anticancer, antiulcer, and antioxidant properties. Despite their importance, only four terpene synthases have been identified from the Zingiberaceae family: (+)-germacrene D synthase and (S)-β-bisabolene synthase from ginger rhizome, and α-humulene synthase and β-eudesmol synthase from shampoo ginger (Zingiber zerumbet) rhizome. We report the identification of 25 mono- and 18 sesquiterpene synthases from ginger and turmeric, with 13 and 11, respectively, being functionally characterized. Novel terpene synthases, (−)-caryolan-1-ol synthase and α-zingiberene/β-sesquiphellandrene synthase, which is responsible for formation of the major sesquiterpenoids in ginger and turmeric rhizomes, were also discovered. These suites of enzymes are responsible for formation of the majority of the terpenoids present in these two plants. Structures of several were modeled, and a comparison of sets of paralogs suggests how the terpene synthases in ginger and turmeric evolved. The most abundant and most important sesquiterpenoids in turmeric rhizomes, (+)-α-turmerone and (+)-β-turmerone, are produced from (−)-α-zingiberene and (−)-β-sesquiphellandrene, respectively, via α-zingiberene/β-sesquiphellandrene oxidase and a still unidentified dehydrogenase.

    Full Text Available The essential oils of ginger (Zingiber officinale and turmeric (Curcuma longa contain a large variety of terpenoids, some of which possess anticancer, antiulcer, and antioxidant properties. Despite their importance, only four terpene synthases have been identified from the Zingiberaceae family: (+-germacrene D synthase and (S-β-bisabolene synthase from ginger rhizome, and α-humulene synthase and β-eudesmol synthase from shampoo ginger (Zingiber zerumbet rhizome. We report the identification of 25 mono- and 18 sesquiterpene synthases from ginger and turmeric, with 13 and 11, respectively, being functionally characterized. Novel terpene synthases, (--caryolan-1-ol synthase and α-zingiberene/β-sesquiphellandrene synthase, which is responsible for formation of the major sesquiterpenoids in ginger and turmeric rhizomes, were also discovered. These suites of enzymes are responsible for formation of the majority of the terpenoids present in these two plants. Structures of several were modeled, and a comparison of sets of paralogs suggests how the terpene synthases in ginger and turmeric evolved. The most abundant and most important sesquiterpenoids in turmeric rhizomes, (+-α-turmerone and (+-β-turmerone, are produced from (--α-zingiberene and (--β-sesquiphellandrene, respectively, via α-zingiberene/β-sesquiphellandrene oxidase and a still unidentified dehydrogenase.

    Many traditional Chinese medicines (TCM), such as Eucommia ulmoides Oliv., Gynostemma pentaphyllum (Thunb.) Makino, and Curcuma longa L., have been reported to have various immune-modulatory effects. To determine the effects of extracts from these three TCM on type 1 T help (Th1)- and Th2-cytokine responses and human leukocyte antigen (HLA)-DR expression in peripheral blood mononuclear cells (PBMCs) obtained from septic patients. Lipopolysaccharide (LPS)-stimulated PBMCs of healthy controls and septic patients were cultured for 48 hs with or without 0.05/0.1 mg/ml of TCM extract. HLA-DR expression in monocytes was detected using flow cytofluorimetry. The interferon [IFN]-γ, tumor necrosis factor [TNF]-α, interleukin (IL)- 2, IL-5, IL-10, and IL-13 levels in supernatants were measured with a human enzyme-linked immunosorbent assay. Treatment with either 0.05 or 0.1 mg/ml of C. longa L. extract significantly restored the percentage of HLA-DR-positive monocytes, which was decreased by LPS in control and patient groups. Treatment with 0.05 or 0.1 mg/ml E. ulmoides Oliv. and C.longa L. extract decreased IL-10 production from LPS-stimulated PBMCs of controls and patients. In patients with sepsis, C. longa L. extract decreased IL-10 production to a greater degree than did E. ulmoides Oliv extract. Although IFN-γ, TNF-α, or IL-13 productions from LPS-stimulated PBMCs were influenced by E. ulmoides Oliv., G. pentaphyllum (Thunb.) Makino, or C. longa L. in control or sepsis groups in this study, only the influence of IL-10 was consistent in both control and sepsis groups. By enhancing monocyte HLA-DR expression and decreasing IL-10 production, C. longa L. might help restore inflammatory responses in septic patients to eradicate pathogens.

    Curcuma longa L. (CL), an Indian herb, has been used to treat many disorders because of its wide spectrum of pharmacological activities. It has been shown to exhibit anti-oxidant and anti-inflammatory properties, and is being used as herbal remedy since ancient times. Osteoarthritis of knee (KOA) is a chronic painful disorder in which prolong use of non-steroidal anti-inflammatory drugs (NSAIDs) or steroids may result into many serious side effects; hence, there is a need to develop herbal drugs, having good analgesia without side effects. Therefore, we planned to evaluate the efficacy of CL in KOA. The study was designed as a randomized, double-blind, placebo-controlled trial in patients of KOA. After obtaining ethical clearance and written informed consent, a total of 160 patients of KOA were randomly enrolled into two groups to receive either CL extract or placebo along with the standard drug regimen. The patients were assessed on day 0, day 60, and day 120. On the days of their visit, the clinical prognosis was assessed by visual analog scale (VAS) and Western Ontario and McMaster Universities (WOMAC) Osteoarthritis index. On these days, the radiographs were also taken for Kellgren and Lawrence grading and blood samples were collected for assessing the changes in levels of IL-1β and biomarkers of oxidative stress, such as reactive oxygen species and malondialdehyde (MDA). Over all significant improvement was observed in the patients of CL extract group as compared to placebo group. Clinically, the VAS and WOMAC scores became better, and simultaneously, the levels of biomarkers, viz., IL-1β, ROS, and MDA, were also significantly (p < 0.05) improved. It may be concluded that on chronic administration, CL suppresses inflammation and brings clinical improvement in patients of KOA, which may be observed by decreased level of IL-1β and VAS/WOMAC scores, respectively. At the same time, CL decreases the oxidative stress also.

    High-energy diets of laying hens may improve roductive performance, although some negative effects may also appear with respect to egg quality and physiological parameters. Curcuma longa rhizome powder (CRP) has beneficial effects on health indices of the birds through antioxidant and antimicrobial properties, especially when the birds experience nutritional stress. Increasing dietary CRP enhanced egg quality by improving eggshell thickness and hardness but decreasing yolk cholesterol content (P < 0.05). The best feed conversion ratio was obtained in birds fed high-apparent metabolizable energy (AME) diets supplemented with 2.0 g kg -1 CRP (P < 0.05). Although increasing dietary AME elevated the serum concentration of triglycerides (P < 0.05) and enzymatic activities of alanine aminotransferase and aspartate aminotransferase (P < 0.05), dietary inclusion of CRP alleviates the blood levels of these enzymes (P < 0.01). Low level of dietary CRP boosted the immune responses to Newcastle virus (P < 0.01) and sheep red blood cells (P < 0.05) antigens but decreased the heterophil to lymphocyte ratio (P < 0.05). Inclusion of at least 2.0 g kg -1 CRP in the diet of laying decreased Escherichia coli enumerations in the ileal content (P < 0.01) and improved villus height, crypt depth and goblet cell numbers (P < 0.05). An improvement in the productive performance of laying hens fed high-energy diets might be associated with decreasing health indices and product quality, which could potentially be amended by nutritional modifications such as incorporating medicinal herbs in the feed. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Full Text Available In this work, the hydrolysis of fresh and dried turmeric (Curcuma longa L. and ginger (Zingiber officinale R. in the presence of subcritical water + CO2 was studied. The hydrolysis of ginger and turmeric bagasses from supercritical fluid extraction was also studied. The reactions were done using subcritical water and CO2 at 150 bar, 200 °C and reaction time of 11 minutes; the degree of reaction was monitored through the amount of starch hydrolyzed. Process yields were calculated using the amount of reducing and total sugars formed. The effects of supercritical fluid extraction in the starchy structures were observed by scanning electron microscopy. Higher degree of hydrolysis (97- 98 % were obtained for fresh materials and the highest total sugar yield (74% was established for ginger bagasse. The supercritical fluid extraction did not significantly modify the degree of hydrolysis in the tested conditions.

    Full Text Available Ethanol extract of turmeric [Curcuma longa Linn. (Zingiberaceae] was investigated for its in vitro antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH radical scavenging assay and activities against six microorganisms (Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphyloccoccus aureus, Candida albicans and Cryptococcus neoformans. Clear liquid soaps containing 0.5% w/v turmeric extract were formulated. The only one preparation with acceptable appearance, foam and viscosity was selected for antimicrobial activity and stability studies. It was found that turmeric extract had 50% radical scavenging ability (EC50 at concentration of 11.26 μg/ml against DPPH. Turmeric extract was showed no activity against Escherichia coli and Pseudomonas aeruginosa. The minimum inhibitory concentration of turmeric extract against Bacillus subtilis, Staphyloccocus aureus, Cryptococcus neoformans and Candida albicans were 16, 128, 128 and 256 μg/ml, respectively. The selected preparation was physically and chemically stable and the antimicrobial activity did not change (p<0.05 under the heating-cooling stability test. However, curcumin content and the antimicrobial activities against S. aureus and C. neoformans decreased significantly (p<0.05 under the accelerated test conditions (temperature 45oC, 75% RH for 4 months and after storage at room temperature for 12 months. The results of a clinical trial with HIV patients found that this liquid soap decreased itching symptom (100% and infectious wound and abscess became dryness scabs (78.6% within 2 weeks.

    Full Text Available Turmeric powder (Curcuma longa L. is valued both for its medicinal properties and for its popular culinary use, such as being a component in curry powder. Due to its high demand in international trade, turmeric powder has been subject to economically driven, hazardous chemical adulteration. This study utilized Fourier Transform-Raman (FT-Raman and Fourier Transform-Infra Red (FT-IR spectroscopy as separate but complementary methods for detecting metanil yellow adulteration of turmeric powder. Sample mixtures of turmeric powder and metanil yellow were prepared at concentrations of 30%, 25%, 20%, 15%, 10%, 5%, 1%, and 0.01% (w/w. FT-Raman and FT-IR spectra were acquired for these mixture samples as well as for pure samples of turmeric powder and metanil yellow. Spectral analysis showed that the FT-IR method in this study could detect the metanil yellow at the 5% concentration, while the FT-Raman method appeared to be more sensitive and could detect the metanil yellow at the 1% concentration. Relationships between metanil yellow spectral peak intensities and metanil yellow concentration were established using representative peaks at FT-Raman 1406 cm−1 and FT-IR 1140 cm−1 with correlation coefficients of 0.93 and 0.95, respectively.

    Fingerprints of 5 temu hitam (Curcuma aeruginosa Roxb.) accessions (Malang, Cirebon, Kuningan 1, Bogor, and Liwa) were determined by thin-layer chromatography (TLC) and compared to fingerprints of turmeric (Curcuma longa L), temu putih (Curcuma zedoaria (Christm.) Roscoe), and temu lawak (Curcuma zanthorriza Roxb.). Maceration method with ethanol as the solvent was used for extraction. The eluent used for fingerprint by TLC was chloroform:dichloromethane (9:1v/v). Five accessions of temu hitam show similar fingerprint patterns, but different in band thickness. Temu hitam rhizomes have bands of curcuminoid (Rf 0.22, 0.10, 0.03), and characteristic bands of Rf 0.42, 0.27, and 0.77, which can be distinguished from turmeric and temu lawak and Rf 0.13, which is different from temu putih. Leaves and stems of temu hitam can be distinguished from temu putih, turmeric, and temu lawak at Rf 0.60. Rhizomes of all plants reveal strong antibacterial activity against Staphylococcus aureus and antioxidant activity on DPPH radicals than its corresponding stems and leaves. Antibacterial and antioxidant activities were determined by microdilution and TLC-bioautography. Antibacterial activity of rhizomes of Cirebon and Kuningan 1 accessions are higher than that of other accessions (MIC = 250 μg/mL MBC = 500 μg/mL, but lower as compared to that of temu lawak (MIC = 62.5 μg/mL, MBC = 250 μg/mL) and tetracycline (MIC = MBC = 15.63 μg/mL). Rhizome of Liwa accession exhibits the highest antioxidant activity (IC50 = 124.88 μg/mL) amongst all accessions, but lower than that of temu lawak (IC50 = 18.45 μg/mL), turmeric (IC50 = 18.82 μg/mL), and temu putih (IC50 = 94.35 μg/mL).

    The aim of the present study was to reveal the possible antiapoptotic effect of turmeric (Curcuma longa Linn.) on the hippocampal neurons of rats exposed to trimethyltin (TMT). Oxidative damage in the hippocampus can induce the apoptosis of neurons associated with the pathogenesis of dementiaMETHODS. The ethanolic turmeric extract and a citicoline (as positive control) solution were administered to the TMT-exposed rats for 28 days. The body weights of rats were recorded once a week. The hippocampal weights and imumunohistochemical expression of caspase 3 proteins in the CA1 and CA2-CA3 regions of the hippocampi were examined at the end of the experiment. Immunohistochemical analysis showed that the injection of TMT increased the expression of caspase 3 in the CA1 and CA2-CA3 regions of hippocampus. TMT also decreased the body and hippocampal weights. Furthermore, the administration of 200 mg/kg bw dose of turmeric extract decreased the caspase 3 expression in the CA2-CA3 pyramidal neurons but not in the CA1 neurons. It also prevented the decrease of the body and hippocampal weights. We suggest that the 200 mg/kg bw dose of turmeric extract may exert antiapoptotic effect on the hippocampal neurons of the TMT-exposed rats (Tab. 1, Fig. 3, Ref. 49).

    Free or loosely chelated iron has tumor-promoting properties in vitro. Curcumin, a polyphenol derived from the food spice turmeric (Curcuma longa), is a potent antioxidant that binds iron. The primary aim of this study was to investigate whether curcuminoids prevent tumor-promoting effects of iron in T51B cells, a non-neoplastic rat liver epithelial cell line. Purified curcuminoids (curcumin) or a standardized turmeric extract similarly reduced oxidative stress and cytotoxicity associated with iron overload (IC 50 values near 10 μM, P turmeric for 16 wk in culture; subsequently assayed by soft agar colony formation) was nearly complete at 20 μM of total curcuminoids (P turmeric extract were taken up better by cells, had a longer half-life, and appeared more effective in blocking tumor promotion (P < 0.01), suggesting enhanced curcuminoid delivery to cells in culture. The primary finding that curcuminoids can inhibit tumor promotion caused by iron in T51B cells is tempered by evidence for an underlying increase in neoplastic transformation at lower concentrations.

    As studies on radiation stability of food dyes are scarce, commercially important natural food grade dyes were evaluated in terms of their sensitivity against gamma ionizing radiation. Cochineal, annatto and turmeric dyes with suitable concentrations were subjected to increasing doses up to 32 kGy and analyzed by spectrophotometry and capillary electrophoresis. The results showed different pattern of absorbance versus absorbed dose for the three systems. Carmine, the glucosidal coloring matter from the scale insect Coccus cacti L., Homoptera (cochineal) remained almost unaffected by radiation up to doses of about 32 kGy (absorbance at 494 nm). Meanwhile, at that dose, a plant-derived product annatto or urucum (Bixa orellana L.) tincture presented a nearly 58% reduction in color intensity. Tincture of curcumin (diferuloylmethane) the active ingredient in the eastern spice turmeric (Curcuma longa) showed to be highly sensitive to radiation when diluted. These data shall be taken in account whenever food products containing these food colors were going to undergo radiation processing. - Highlights: • Comparison of radiosensitivity of food colors was performed. • Carmine showed the highest resistance to radiation. • Annatto and turmeric behaved sensitive to radiation when diluted. • Turmeric was the most affected by ionizing radiation.

    To investigate the effects of rapid anesthesia and long-term sedation with the essential oils (EOs) of Myrcia sylvatica (EOMS) and Curcuma longa (EOCL) on biochemical and oxidative parameters in matrinxã. Prospective, randomized, laboratory experiment. A total of 72 matrinxã (Brycon amazonicus) adults weighing 404.8 ± 27.9 g were divided into eight groups of nine fish. Biochemical and oxidative effects were investigated in plasma and tissues of matrinxã subjected to rapid anesthesia (5 minutes) or long-term sedation (360 minutes, simulating the practice of transport) with EOMS (200 μL L -1 and 10 μL L -1 , respectively) and EOCL (500 μL L -1 and 40 μL L -1 , respectively). Transport simulation without sedation or anesthesia increased lipid peroxidation levels in the gills and kidney of fish in the control group. Anesthesia and sedation with EOs decreased cortisol concentrations and increased lactate concentrations compared with controls. Lipid peroxidation was lower in the brain, gills, liver and kidney of sedated and anesthetized fish, than in the control group. Anesthesia with EOs increased the activity of superoxide dismutase and glutathione-S-transferase in the brain, and catalase in the liver and gills, compared with controls. Long-term sedation with EOs increased superoxide dismutase, glutathione peroxidase and glutathione reductase activities in the brain, catalase in the liver, glutathione peroxidase and glutathione reductase in the gills and superoxide dismutase in the kidney. In general, nonprotein thiols content and total reactive antioxidant potential of tissues were higher after anesthesia and sedation with EOs compared with the control group. The concentrations of EOMS and EOCL used were effective at preventing a stress response and excess of reactive oxygen species formation. For these reasons, these substances may be recommended for use in the transportation of fish to improve survival and animal welfare. Copyright © 2017

    Essential oils and extract of Curcuma longa, ar-turmerone, and curcuminoids were evaluated for their larvicidal and deterrent activity against mosquitoes. Ar-turmerone and curcuminoids constituted 36.9, 24.9 and 50.6% of rhizome oil, leaf oil, and rhizome extract, respectively. Ar-turmerone was the major compound of the rhizome oil (36.9%) and leaf oil (24.9%). The ethanolic extract had 15.4% ar-turmerone with 6.6% bisdesmethoxycurcumin, 6.1% desmethoxycurcumin, and 22.6% curcumin. In in vitro studies, essential oils of the leaf (biting deterrence index [BDI] = 0.98), rhizome (BDI = 0.98), and rhizome ethanolic extract (BDI = 0.96) at 10 µg/cm(2) showed biting deterrent activity similar to DEET at 25 nmol/cm(2) against Aedes aegypti L. Among the pure compounds, ar-turmerone (BDI = 1.15) showed the biting deterrent activity higher than DEET at 25 nmol/cm(2) whereas the activity of other compounds was lower than DEET. In Anopheles quadrimaculatus Say, only ar-turmerone showed deterrent activity similar to DEET. In dose-response bioassay, ar-turmerone showed significantly higher biting deterrence than DEET at all the dosages. Ar-turmerone, at 15 nmol/cm(2), showed activity similar to DEET at 25 nmol/cm(2) and activity at 5 nmol/cm(2) was similar to DEET at 20 and 15 nmol/cm(2). Leaf essential oil with LC(50) values of 1.8 and 8.9 ppm against larvae of An. quadrimaculatus and Ae. aegypti, respectively, showed highest toxicity followed by rhizome oil and ethanolic extract. Among the pure compounds, ar-turmerone with LC(50) values of 2.8 and 2.5 ppm against larvae of An. quadrimaculatus and Ae. aegypti, respectively, was most toxic followed by bisdesmethoxycurcumin, curcumin, and desmethoxycurcumin. © The Authors 2015.

    Full Text Available The stability of active constituents (curcuminoids and volatile oil in turmeric (Curcuma longa Linn. rhizomes and zedoary [Curcuma zedoaria (Berg. Roscoe] bulb and finger rhizomes during storage have been investigated. They were prepared as sliced and powdered and separately packed, either in black polyethylene bags or in paper bags, and stored at room temperature (28-31oC. Samples at initial and three monthly intervals were examined over 12-15 months storage to determine the contents of curcuminoids, volatile oil and moisture. The results showed that storage of rhizomes in black polyethylene bags could prevent samples from taking up moisture better than those stored in paper bags. The sliced and powderedturmeric rhizomes exhibited no decrease in curcuminoids content after 15 months of storage irrespective of the nature of the packing material. However, the slices of zedoary (bulb and finger rhizomes lost curcuminoids to a lesser extent than powdered rhizomes during storage period. Volatile oil content of turmeric rhizomes, zedoary (bulb and finger rhizomes decreased slower when stored as slices rather than as powders. The result from the present study suggested that in order to maintain the quality of turmeric and zedoary rhizomes as raw material for food and medicinal uses, they should be prepared in sliced form and stored in black polyethylene bags in order to maintain their content of active constituents during storage period.

    Although ligand fishing has been shown to be an efficient technique for the identification of bioactive components from complex mixtures such as natural products, it cannot be applied to biomedical image processing. Herein, a specific fluorescent ligand fishing combined with in situ imaging approach is presented for the identification of heat shock protein 90 (Hsp 90) inhibitors from complex matrixes, Curcuma longa L., using N-terminus immobilized Hsp 90α functionalized InP/ZnS quantum dots embedded mesoporous nanoparticles (i.e. Hsp 90α (NT)-FQDNs) as extraction sorbents and fluorescent tracer. The fished ligands were identified by liquid chromatography time-of-flight/mass spectrometry (LC-TOF/MS) and gas chromatography-mass spectrometry (GC-MS). Moreover, in situ imaging by confocal laser scanning microscopy (CLSM) was applied for evaluating the effect of fished-ligands on bioactivity-induced apoptosis morphologically in HeLa cells. MTT assay verified the bioactivity of the ligands and molecular docking results further provided convincing information to verify the feasible binding mode between ligands and protein. Twelve ligands as potential Hsp 90 inhibitors were ultimately fished and identified from Curcuma longa L. crude extracts. The proposed approach based on Hsp 90α functionalized nanocomposites is superior in the combination of highly specific screening efficiency and concurrent visual in situ imaging, which could have great promise for the development of other plant-derived Hsp 90 inhibitors, and providing a rapid and reliable platform for discovering biologically active molecules in natural products.

    Adipocyte lipid accumulation due to impaired fatty acid oxidation causes adipocyte hypertrophy and adipose tissue increment, leading to obesity. The aim of this study was to determine the antiobesity effects of the herbal composition Gambigyeongsinhwan (4) (GGH(4)) composed of Curcuma longa L. (Zingiberaceae), Alnus japonica (Thunb.) Steud. (Betulaceae), and the fermented traditional Korean medicine Massa Medicata Fermentata. The effects of GGH(4) and the individual components on lipid accumulation in 3T3-L1 adipocytes and body weight gain in Otsuka Long-Evans Tokushima Fatty (OLETF) rats were examined using Oil red O staining, hematoxylin and eosin staining, quantitative real-time PCR, and peroxisome proliferator-activated receptor α (PPARα) transactivation assay. GGH(4), individual components, and an active principle of Curcuma longa curcumin inhibited lipid accumulation and mRNA levels of adipocyte-specific genes (PPARγ, aP2, and C/EBPα) in 3T3-L1 adipocytes compared with control cells. Treatment with GGH(4), the individual components or curcmumin increased mRNA levels of mitochondrial (CPT-1, MCAD, and VLCAD) and peroxisomal (ACOX and thiolase) PPARα target genes. GGH(4) and the individual components also increased PPARα reporter gene expression compared with control cells. These effects were most prominent in GGH(4)-treated cells. However, the PPARα antagonist GW6471 reversed the inhibitory effects of GGH(4) on adipogenesis. An in vivo study showed that GGH(4) decreased body weight gain, adipose tissue mass, and visceral adipocyte size with increasing mRNA levels of adipose tissue PPARα target genes in OLETF rats. These results demonstrate that GGH(4) has an antiobesity effects through the inhibition of adipocyte lipid accumulation, and this process may be mediated in part through adipose PPARα activation.

    Curcuma longa Linn. (Zingiberaceae) commonly known as turmeric has long been used for centuries as a spice and household remedy. The present study was carried out to assess the possible mutagenic potential and acute oral toxicity of polysaccharide extract of turmeric rhizome (NR-INF-02) using standard tests. The standard battery of in vitro genotoxicity tests, bacterial reverse mutation test (BRMT), chromosome aberration (CA), and micronucleus (MN) tests were employed to assess the possible mutagenic activity of NR-INF-02 (Turmacin). The results showed no mutagenic effect with NR-INF-02 up to a dose of 5000 µg/mL in BRMT. The results on CA and MN tests revealed the non clastogenic activity of NR-INF-02 in a dose range of 250.36 to 2500 µg/mL with and without metabolic activation (S9). In acute oral toxicity study, NR-INF-02 was found to be safe up to 5 g/kg body weight in Wistar rats. Overall, results indicated that polysaccharide extract of C. longa was found to be genotoxically safe and also exhibited maximum tolerable dose of more than 5 g/kg rat body weight. PMID:24455673

    Tardive dyskinesia (TD) is a motor disorder of the orofacial region resulting from chronic neuroleptic treatment. A high incidence and irreversibility of this hyperkinetic disorder has been considered a major clinical issue in the treatment of schizophrenia. The molecular mechanism related to the pathophysiology of tardive dyskinesia is not completely known. Various animal studies have demonstrated an enhanced oxidative stress and increased glutamatergic transmission as well as inhibition in the glutamate uptake after the chronic administration of haloperidol. The present study investigated the effect of curcumin, an antioxidant, in haloperidol-induced tardive dyskinesia by using different behavioural (orofacial dyskinetic movements, stereotypy, locomotor activity, % retention), biochemical (lipid peroxidation, reduced glutathione levels, antioxidant enzyme levels (SOD and catalase) and neurochemical (neurotransmitter levels) parameters. Chronic administration of haloperidol (1 mg/kg i.p. for 21 days) significantly increased vacuous chewing movements (VCM's), tongue protrusions, facial jerking in rats which was dose-dependently inhibited by curcumin. Chronic administration of haloperidol also resulted in increased dopamine receptor sensitivity as evident by increased locomotor activity and stereotypy and also decreased % retention time on elevated plus maze paradigm. Pretreatment with curcumin reversed these behavioral changes. Besides, haloperidol also induced oxidative damage in all major regions of brain which was attenuated by curcumin, especially in the subcortical region containing striatum. On chronic administration of haloperidol, there was a decrease in turnover of dopamine, serotonin and norepinephrine in both cortical and subcortical regions which was again dose-dependently reversed by treatment with curcumin. The findings of the present study suggested for the involvement of free radicals in the development of neuroleptic-induced tardive dyskinesia and point to curcumin as a possible therapeutic option to treat this hyperkinetic movement disorder.

    Full Text Available Background: Recent studies have suggested increased levels of pro-inflammatory cytokines in depression. Aim: The present study aimed to evaluate the effect of extracts from Rhodiola and Curcuma on immunoreactivity of animals subjected to a chronic mild stress (CMS model followed by lipopolysaccharide-induced inflammation. Materials and methods: Male Wistar rats (n=56 divided in 7 groups were treated orally with: distilled water 10 ml/kg (control and CMS model groups; Rhodiola 250 mg/kg; Rhodiola 500 mg/kg; Curcuma 250 mg/kg; Curcuma 500 mg/kg, Rhodiola 250 mg/kg and Curcuma 250 mg/kg. All groups except the control were stressed daily according to a CMS protocol. Changes in glucose preference, weight gain and locomotor activity were recorded. In the sixth week the animals were challenged with LPS and rats’ sera were obtained for ELISA evaluation of TNF-α and IL-6 levels. Results: The animals from the model group decreased their weight gain, glucose preference and locomotor activity compared to controls. The groups exposed to stress and treated with Rhodiola 500 mg/kg, Curcuma 500 mg/kg and their combination increased their locomotor activity compared to the model group. High expression of the pro-inflammatory cytokines TNF-α and IL-6 were found in all groups exposed to CMS and challenged by LPS. Conclusions: The groups exposed to the stress procedure showed a variety of depression-like behavioral changes. In addition, ELISA tests showed that CMS is affecting rats’ immunity by increasing the cytokines’ levels. These changes could be reversed by administration of Rhodiola and Curcuma in combination suggesting synergic interaction regarding their anti-inflammatory and anti-stress effects.

    The blending of transformer oil (used mainly as an insulating oil) with appropriate synthetic antioxidants, such as BHT (2,6-di-tert-butyl-4-methylphenol) and DBP (2,6-di-tert-butylphenol) have been previously reported. This article is focused on the use of antioxidant extracts from turmeric (Curcuma longa), a natural source. Turmeric is well known for its antimicrobial, antioxidant and anticarcinogenic properties owing to the active nature of its components. Extracts from powdered turmeric were subsequently blended into naphthenic-based uninhibited virgin transformer oil, hereinafter referred to as extract-oil blends (E-OB). Thin-layer chromatography (TLC) of the oil blends revealed that five components extracted from turmeric powder were successfully blended into the oil. Subsequent gas chromatography-mass spectrometry (GC-MS) analysis confirmed the presence of the compounds: curcumene, sesquiphellandrene, ar-turmerone, turmerone and curlone. Thermogravimetric analysis (TGA) of the extract-oil blends, containing various levels of extracts, revealed an average temperature shift of ˜8.21°C in the initial onset of degradation in comparison to virgin non-blended oil. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay showed that an increase in the mass aliquot of turmeric extracts in the transformer oil increased the free radical scavenging activity of the oil. Electrical properties of the oil investigated showed that the dissipation factor in the blended oil was found to be lower than that of virgin transformer oil. Evidently, a lower dissipation value renders the oil blend as a superior insulator over normal virgin non-blended oil. This investigation elucidated improved physico-chemical properties of transformer oil blended with turmeric antioxidant extracts.

    Curcuma longa L. is a well-known medicinal plant that has been used for its anti-cancer, neuroprotective, and hepatoprotective effects. However, the neuroprotective effect of fermented C. longa (FCL) has not been reported. Therefore, in this study, the effectiveness of FCL for the regulation of memory dysfunction was investigated in two brain cell lines (rat glioma C6 and murine microglia BV2) and scopolamine-treated mice. C. longa powder was fermented by 5% Lactobacillus plantarum K154 containing 2% (w/v) yeast extract at 30 °C for 72 h followed by sterilization at 121 °C for 15 min. The protective effects of fermented C. longa (FCL) on oxidative stress induced cell death were analyzed by MTT assay in C6 cells. The anti-inflammatory effects of FCL were investigated by measuring the production of nitric oxide (NO) and prostaglandin E 2 (PGE 2 ) as well as the expression levels of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) in LPS-stimulated BV2 cells. The step-through passive avoidance test, Morris water maze test, acetylcholinesterase (AChE) activity, and expression of cAMP response element-binding protein (CREB) and brain-derived neurotropic factor (BDNF) were employed to determine the effects of FCL on scopolamine-induced memory deficit in mice. The contents of curcuminoids were analyzed through LC/MS. Pretreatment with FCL effectively prevented the cell death induced by oxidative stress in C6 cells. Moreover, FCL inhibited the production NO and PGE 2 via the inhibition of iNOS and COX-2 expression in BV2 cells. FCL significantly attenuated scopolamine-induced memory impairment in mice and prevented scopolamine-induced AChE activity in the hippocampus. Additionally, FCL reversed the reduction of CREB and BDNF expression. The curcuminoids content in FCL was 1.44%. FCL pretreatment could alleviate scopolamine-induced memory impairment in mice, as well as oxidative stress and inflammation in C6 and BV2 cells, respectively. Thus, FCL might be a

    This study was carried out to provide scientific basis for the medicinal use of turmeric (Curcuma longa) in gastrointestinal and respiratory disorders. The crude extract of turmeric (Cl.Cr), relaxed the spontaneous and K+ (80 mM)-induced contractions in isolated rabbit jejunum as well as shifted the CaCl2 concentration-response curves. In rabbit tracheal preparation, Cl.Cr inhibited carbachol and K(+)-induced contractions. In anesthetized rats, Cl.Cr produced variable responses on blood pressure with a mixture of weak hypertensive and hypotensive actions. In rabbit aorta, Cl.Cr caused a weak vasoconstrictor and a vasodilator effect on K+ and phenylephrine-induced contractions. In guinea-pig atria, Cl.Cr inhibited spontaneous rate and force of contractions at 14-24 times higher concentrations. Activity directed fractionation revealed that the vasodilator and vasoconstrictor activities are widely distributed in the plant with no clear separation into the polar or non-polar fractions. When used for comparison, both curcumin and verapamil caused similar inhibitory effects in all smooth muscle preparations with relatively more effect against K(+)-induced contractions and that both were devoid of any vasoconstrictor effect and curcumin had no effect on atria. These data suggest that the inhibitory effects of Cl.Cr are mediated primarily through calcium channel blockade, though additional mechanism cannot be ruled out and this study forms the basis for the traditional use of turmeric in hyperactive states of the gut and airways. Furthermore, curcumin, the main active principle, does not share all effects of turmeric.

    Tamoxifen is a drug wildly used for the adjuvant therapy in the treatment of women with estrogen receptor-positive breast tumors and has a low incidence of serious side-effects. Feeding turmeric ( Curcuma longa L .) to rats has no apparent side effects; reduced the types of inflammation that can cause liver cell damage, blockage and scarring. Turmeric delay the damage caused by progressive inflammatory liver disease. This study was carried out to study the possible therapeutic effect of polyphenyl constituents in turmeric and tamoxifen on hepatocarcinogenesis in rats chemically induced by diethylnitrosamine (DEN). Thirty five male rats were injected with DEN in a single dose i.p. (200mg/kg), 7 rats were sacrificed after ~6 months for histopathological examination for HCC nodules in different lobes and lobules, many nodules were observed by naked eye with a diameter of about ~2-3mm. The remaining 28 hepatoma (HCC) bearing rats chemically induced were randomized divided into 4 groups (each of 7rats): hepatoma bearing rats receiving the control diet; hepatoma bearing rats (supplemented with 4g/kg (wt/wt) turmeric (~200 μg curcumin /rat/day/4weeks; hepatoma bearing rats treated with 50mg/kg (wt/wt) tamoxifen dissolved in 0.1 ml dimethylsulfoxide and diluted with normal saline and drinking water; hepatoma bearing rats treated with 50mg/kg (wt/wt) tamoxifen in 0.1 ml dimethylsulfoxide and diluted with normal saline and drinking water and supplemented with 4g/ kg (wt/wt) turmeric(~200 μg curcumin /rat/day/4weeks; besides, 7 male rats serves as control group. By the end of the experiment at 4 weeks, rats in each group were sacrificed for examination.

    Synergistic effect of supercritical CO2 extracts of Curcuma species with conventional chemotherapeutic drugs was investigated in human alveolar (SJRH30) and embryonal (RD) rhabdomyosarcoma cell lines. The Curcuma amada (mango ginger) (CA) extract showed the highest levels of cytotoxicity with inhibitory concentration IC50 values of 7.133 µg/ml and 7.501 µg/ml for SJRH30 and RD cell lines, respectively, as compared with Curcuma longa (turmeric) and Curcuma xanthorrhiza (Javanese turmeric) extracts. CA showed synergistic cytotoxic effects with vinblastine (VBL) and cyclophosphamide (CP) as indicated by the combination index values of <1 for VBL + CA, CP + CA, and VBL + CP + CA combinations in both embryonal and alveolar rhabdomyosarcomas. When lower doses of CA (0.1-0.2 µg/ml) were combined with cancer drugs like CP and VBL, caspase-3 activity increased significantly compared with individual agents and correlated with the percentage of apoptotic cells. CA in combination with VBL and CP induced a higher percentage of apoptosis than single agents in both cell lines. CA also modulated the expression of genes associated with intrinsic pathway of apoptosis (Bcl-2, Bax, Bak, and p53) and also inhibited the expression of genes associated with inflammation such as COX-2 and NF-κB. Xenograft studies with SJRH30 tumors in nude mice showed that CA treatment inhibited tumor growth rate with and without VBL and increased the survival rate significantly. These results suggest that CA can be evaluated further as an adjuvant with cancer drugs for the treatment of rhabdomyosarcoma patients. Copyright © 2015 John Wiley & Sons, Ltd.

    As studies on radiation stability of food dyes are scarce, commercially important natural food grade dyes were evaluated in terms of their sensitivity against gamma ionizing radiation. Cochineal, annatto and turmeric dyes with suitable concentrations were subjected to increasing doses up to 32 kGy and analyzed by spectrophotometry and capillary electrophoresis. The results showed different pattern of absorbance versus absorbed dose for the three systems. Carmine, the glucosidal coloring matter from the scale insect Coccus cacti L., Homoptera (cochineal) remained almost unaffected by radiation up to doses of about 32 kGy (absorbance at 494 nm). Meanwhile, at that dose, a plant-derived product annatto or urucum (Bixa orellana L.) tincture presented a nearly 58% reduction in color intensity. Tincture of curcumin (diferuloylmethane) the active ingredient in the eastern spice turmeric (Curcuma longa) showed to be highly sensitive to radiation when diluted. These data shall be taken in account whenever food products containing these food colors were going to undergo radiation processing.

    The immune response is stimulated to protect the body from external antigens and is controlled by several types of immune cells. In the present study, the immunomodulatory effects of Curcuma longa L., purple sweet potato, and mixtures of the two (CPM) were investigated in C57BL/6 mice infected with LP-BM5 murine leukemia virus (MuLV). Mice were divided into seven groups as follows: normal control, infected control (LP-BM5 MuLV infection), positive control (LP-BM5 MuLV infection+dietary supplement of red ginseng 300 mg/kg body weight), the original powder of C. longa L. (C; LP-BM5 MuLV infection+dietary supplement of C 189 mg/kg body weight), the original powder of purple sweet potato (P; LP-BM5 MuLV infection+dietary supplement of P 1811 mg/kg body weight), CPM Low (CPL; LP-BM5 MuLV infection+CPM 2 g/kg body weight), and CPM High (CPH; LP-BM5 MuLV infection+CPM 5 g/kg body weight). Dietary supplementation lasted for 12 weeks. Dietary supplementation of CPM inhibited LP-BM5 MuLV-induced lymphadenopathy and splenomegaly and inhibited reduction of messenger RNA (mRNA) expression of major histocompatibility complex (MHC) I and II. Moreover, CPM reduced the decrease in T- and B cell proliferation, reduced the population of CD4(+)/CD8(+) T cells, and remedied the unbalanced production of T helper-1 (Th1)/T helper-2 (Th2) cytokines in LP-BM5 MuLV-infected mice. In addition, CPM inhibited reduction of phagocytosis in peritoneal macrophages and decreased serum levels of immunoglobulin A (IgA), immunoglobulin E (IgE), and immunoglobulin G (IgG). These results suggest that CPM had a positive effect on immunomodulation in C57BL/6 mice induced by LP-BM5 leukemia retrovirus infection.

    Curcuma longa is a perennial member of the Zingiberaceae family, and cultivated mainly in India, and Southeast Asia. The hypothesis for this study is that turmeric will have distinctive effects from curcumin due to the presence of other bioactive compounds. Thirty Eight-week old Sprague-Dawley rats were separated into 3 oral feeding groups. Group 1, standard rat chow, Control diet - AIN 93M, group 2 Curcumin- 700 ppm or 0.7 g/kg diet, and group 3 - Turmeric -14,000 ppm or 14 g/kg diet for a total of 3 weeks. One group of rats were feed all three diets only and another group underwent esophagoduodenal anastomosis to evaluate the effects of bioavailability. Curcumin diet did not increase the transcription of mRNA of TNF-alpha, IL-6, iNOS and COX-2. The average fold change in the mRNAs level was not significant. Whereas turmeric diet increases the levels of IL-6 (1.9 fold, p=0.05) iNOS (4.39 fold, p=0.02), IL-8 (3.11 fold, p=0.04) and COX-2 (2.02 fold, p=0.05), suggesting that turmeric either was more bioavailabile or had more affect on pro-inflammatory genes compare to curcumin diet. We have demonstrated the molecular effects of curcumin and turmeric in the role as an anti-inflammatory therapy. However, significant bioavailable differences do occur and must be considered in further chemopreventative investigative trials the setting of reflux esophagitis, Barrett’s esophagus, and other upper gastrointestinal cancers.

Methods and Materials: For the assay of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in urine, a marker for acute effects, Wistar-MS virgin rats were fed the basal diet with exposure at 0 or 3 Gy to γ-rays from a 60 Co source as the control. Rats in the experimental groups received whole-body irradiation with 3 Gy and were fed a diet containing 1% (wt/wt) curcumin for 3 days before and/or 2 days after irradiation. The urine was collected for a 24-h period between 1 and 2 days after irradiation. Urine samples were used to determine the 8-OHdG level using an enzyme-linked immunosorbent assay and the creatinine level by a modified Jaffe reaction. For long-term effects, rats at Day 17 of pregnancy were fed a diet containing curcumin for 3 days before and/or 3 days after irradiation with 1.5 Gy, and received a pellet of diethylstilbestrol as the promoter. The rats were examined for mammary and pituitary tumors for 1 year. To determine survival, virgin rats received whole-body irradiation with 9.6 Gy and were fed a diet containing curcumin for 3 days before and/or 3 days after irradiation. After irradiation, all rats were assessed daily for survival for 30 days. Results: Acutely in virgin rats irradiated with 3 Gy, the creatinine-corrected concentration and total amount of 8-OHdG in the 24-h urine samples were higher (approximately 1.3-fold) than the corresponding values in the nonirradiated controls. Adding curcumin to the diet for 3 days before and/or 2 days after irradiation reduced the elevated 8-OHdG levels by 50-70%. The evaluation of the protective action of curcumin against the long-term effects revealed that curcumin significantly decreased the incidence of mammary and pituitary tumors. However, the

    Curcumin is the major constituent of turmeric (Curcuma longa L.). It has attracted widespread attention for its anticancer and anti-inflammatory activities. The separation of curcumin and its two close analogs, demethoxycurcumin and bisdemethoxycurcumin, has been challenging by conventional techniques. In this study, an environmentally friendly method based on supercritical fluid chromatography was established for the rapid and facile separation of the three curcuminoids directly from the methanol extract of turmeric. The method was first developed and optimized by ultra performance convergence chromatography, and was then scaled up to preparative supercritical fluid chromatography. Eluted with supercritical fluid CO2 containing 8-15% methanol (containing 10 mM oxalic acid) at a flow rate of 80 mL/min, curcumin, demethoxycurcumin and bisdemethoxycurcumin could be well separated on a Viridis BEH OBD column (Waters, 250 mm × 19 mm, 5 μm) within 6.5 min. As a result, 20.8 mg of curcumin (97.9% purity), 7.0 mg of demethoxycurcumin (91.1%), and 4.6 mg of bisdemethoxycurcumin (94.8%) were obtained after a single step of supercritical fluid chromatography separation with a mean recovery of 76.6%. Showing obvious advantages in low solvent consumption, large sample loading, and easy solvent removal, supercritical fluid chromatography was proved to be a superior technique for the efficient separation of natural products. © 2015 WILEY-VCH Verlag GmbH & Co.

    Background Among the naturally occurring compounds, turmeric from the dried rhizome of the plant Curcuma longa has long been used extensively as a condiment and a household remedy all over Southeast Asia. Turmeric contains essential oil, yellow pigments (curcuminoids), starch and oleoresin. The present study was designed for investigating the neuroprotective efficacy and the time window for effective therapeutic use of Curcuma oil (C. oil). Method In the present study, the effect of post ischemic treatment of C.oil after ischemia induced by occlusion of the middle cerebral artery in the rat was observed. C.oil (500 mg/kg body wt) was given 4 hrs post ischemia. The significant effect on lesion size as visualized by using diffusion-weighted magnetic resonance imaging and neuroscore was still evident when treatment was started 4 hours after insult. Animals were assessed for behavioral deficit scores after 5 and 24 hours of ischemia. Subsequently, the rats were sacrificed for evaluation of infarct and edema volumes and other parameters. Results C.oil ameliorated the ischemia induced neurological functional deficits and the infarct and edema volumes measured after 5 and 24 hrs of ischemia. After 24 hrs, immunohistochemical and Western blot analysis demonstrated that the expression of iNOS, cytochrome c and Bax/Bcl-2 were altered after the insult, and antagonized by treatment with C.oil. C.oil significantly reduced nitrosative stress, tended to correct the decreased mitochondrial membrane potential, and also affected caspase-3 activation finally apoptosis. Conclusion Here we demonstrated that iNOS-derived NO produced during ischemic injury was crucial for the up-regulation of ischemic injury targets. C.oil down-regulates these targets this coincided with an increased survival rate of neurons. PMID:18826584

    Curcuma spp. (Zingiberaceae) is one of the significant ingredients in food and traditional medicines. The current study was to investigate health-benefits of the rhizomes of endemic Curcuma caesia, Curcuma zedoaria and Curcuma aeruginosa using in vitro antioxidant, antiinflammatory and human tumor cell proliferation inhibitory activities. Among these, C. caesia (black turmeric) showed the best overall biological activities based on [3-(4, 5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide] (MTT) and lipid peroxidation (LPO), cyclooxygenase (COX-1 and -2) enzymes, and tumor cell growth inhibitory assays. The hexane and methanolic extracts of C. caesia (CCH and CCM) showed LPO inhibition by 31 and 43 %, and COX-2 enzyme by 29 and 38 %, respectively, at 100 μg/ml. Eleven terpenoids were isolated and identified. The MTT antioxidant assay revealed that the extracts of three Curcuma spp. at 250 μg/ml and isolates at 5 μg/ml demonstrated activity comparable to positive controls vitamin C and t-butyl hydroquinone (TBHQ) at 25 μg/ml. The extracts inhibited LPO by 40 % at 250 μg/ml whereas pure isolates 1-11 by about 20 %. The extracts and isolates inhibited COX-1 and -2 enzymes between the ranges of 3-56 and 5-30 %, respectively. The in vitro biological activity exhibited by the extracts and isolates of C. caesia rhizome further supported its use in traditional medicine.

    The proteases from turmeric species have procoagulant and fibrinogenolytic activity. This provides a scientific basis for traditional use of turmeric to stop bleeding and promote wound healing processes. Our previous studies revealed that fibrinogenolytic action of crude enzyme fraction of Curcuma aromatica Salisb., was found to be more influential than those of Curcuma longa L., Curcuma caesia Roxb., Curcuma amada Roxb. and Curcuma zedoria (Christm.) Roscoe. Hence, the purpose of this study is to purify and characterize protease from C. aromatica and to explore its role in wound healing process. The protease was purified by Sephadex G-50 gel permeation chromatography. Peak with potent proteolytic activity was subjected to rechromatography and then checked for homogeneity by SDS-PAGE and native PAGE. Furthermore purity of the peak was assessed by RP-HPLC and MALDI-TOF. The biochemical properties, type of protease, kinetic studies, fibrinogenolytic, coagulant and fibrinolytic activities were carried out. The two proteolytic peaks were fractionated in gel permeation chromatography. Among these, the peak-II showed potent proteolytic activity with specific activity of 10units/mg/min and named as C. aromatica protease-II (CAP-II). This protein resolved into a single sharp band both in SDS-PAGE (reducing and non-reducing) as well as in native (acidic) PAGE. It is a monomeric protein, showing sharp peak in RP-HPLC and its relative molecular mass was found to be 12.378kDa. The caseinolytic and fibrinolytic activity of CAP-II was completely inhibited by phenylmethylsulfonylfluoride (PMSF). The CAP-II exhibited optimum temperature of 45°C and optimum pH of 7.5. The Km and Vmax of CAP-II was found to be 1.616µg and 1.62units/mg/min respectively. The CAP-II showed hydrolysis of all three subunits of fibrinogen in the order Aα>Bß>γ. The CAP-II exhibited strong procoagulant activity by reducing the human plasma clotting time. It also showed fibrinolytic activity by complete

    Background Ginger (Zingiber officinale) and turmeric (Curcuma longa) accumulate important pharmacologically active metabolites at high levels in their rhizomes. Despite their importance, relatively little is known regarding gene expression in the rhizomes of ginger and turmeric. Results In order to identify rhizome-enriched genes and genes encoding specialized metabolism enzymes and pathway regulators, we evaluated an assembled collection of expressed sequence tags (ESTs) from eight different ginger and turmeric tissues. Comparisons to publicly available sorghum rhizome ESTs revealed a total of 777 gene transcripts expressed in ginger/turmeric and sorghum rhizomes but apparently absent from other tissues. The list of rhizome-specific transcripts was enriched for genes associated with regulation of tissue growth, development, and transcription. In particular, transcripts for ethylene response factors and AUX/IAA proteins appeared to accumulate in patterns mirroring results from previous studies regarding rhizome growth responses to exogenous applications of auxin and ethylene. Thus, these genes may play important roles in defining rhizome growth and development. Additional associations were made for ginger and turmeric rhizome-enriched MADS box transcription factors, their putative rhizome-enriched homologs in sorghum, and rhizomatous QTLs in rice. Additionally, analysis of both primary and specialized metabolism genes indicates that ginger and turmeric rhizomes are primarily devoted to the utilization of leaf supplied sucrose for the production and/or storage of specialized metabolites associated with the phenylpropanoid pathway and putative type III polyketide synthase gene products. This finding reinforces earlier hypotheses predicting roles of this enzyme class in the production of curcuminoids and gingerols. Conclusion A significant set of genes were found to be exclusively or preferentially expressed in the rhizome of ginger and turmeric. Specific

    Curcuminoids, namely curcumin and its analogs, are secondary metabolites that act as the primary active constituents of turmeric (Curcuma longa). The contents of these curcuminoids vary among species in the genus Curcuma. For this reason, we compared two wild strains and two cultivars to understand the differences in the synthesis of curcuminoids. Because the fluxes of metabolic reactions depend on the amounts of their substrate and the activity of the catalysts, we analyzed the metabolite concentrations and gene expression of related enzymes. We developed a method based on RNA sequencing (RNA-Seq) analysis that focuses on a specific set of genes to detect expression differences between species in detail. We developed a 'selection-first' method for RNA-Seq analysis in which short reads are mapped to selected enzymes in the target biosynthetic pathways in order to reduce the effect of mapping errors. Using this method, we found that the difference in the contents of curcuminoids among the species, as measured by gas chromatography-mass spectrometry, could be explained by the changes in the expression of genes encoding diketide-CoA synthase, and curcumin synthase at the branching point of the curcuminoid biosynthesis pathway. © The Author 2015.

    Turmeric is obtained from the plant Curcuma longa L; its major constituent, curcumin, is a polyphenol with multiple effects which can modulate some signaling pathways. Insulin resistance is a major risk factor for chronic diseases such as type 2 diabetes, atherosclerotic, metabolic syndrome and cardiovascular disease. In addition, Insulin resistance in peripheral tissue is one of the most important reasons of hyperglycemia which can cause global or systemic effects. The present study reviewed studies published in PubMed from 1998 to 2013, indicating the role of curcumin in attenuation of many pathophysiological processes involved in development and progression of hyperglycemia and insulin resistance. Curcumin can reduce blood glucose level by reducing the hepatic glucose production, suppression of hyperglycemia-induced inflammatory state, stimulation of glucose uptake by up-regulation of GLUT4, GLUT2 and GLUT3 genes expressions, activation of AMP kinase, promoting the PPAR ligand-binding activity, stimulation of insulin secretion from pancreatic tissues, improvement in pancreatic cell function, and reduction of insulin resistance. Curcumin has antihyperglycemic and insulin sensitizer effects. Thereby, more studies evaluating the effects of curcumin on hyperglycemic state and insulin resistance in related disorders such as diabetes are recommended.

    Pressurized hot water extraction (PHWE, also known as subcritical water extraction) is commonly considered to be an environmentally friendly extraction technique that could potentially replace traditional methods that use organic solvents. Unfortunately, the applicability of this technique is often limited by the very low water solubility of the target compounds, even at high temperatures. In this paper, the scope for broadening the applicability of PHWE by adjusting the pH of the water used in the extraction is demonstrated in the extraction of curcumin (which exhibits very limited water solubility) from untreated turmeric (Curcuma longa L.) rhizomes. Although poor extraction yields were obtained, even at high temperatures when using degassed water or neutral phosphate buffer as the extraction medium, yields exceeding those obtained by Soxhlet extraction were achieved using highly acidic pH buffers due to curcumin protonation. The influence of the temperature, pH, and buffer concentration on the extraction yield were investigated in detail by means of a series of designed experiments. Optimized conditions for the extraction of curcumin from turmeric by PHWE were estimated at 197 °C using 62 g/L buffer concentration at pH 1.6. The relationships between these variables were subjected to statistical analysis using response surface methodology.

    Full Text Available We aimed to compare the anti-inflammatory activities of six species of Curcuma drugs using adjuvant arthritis model mice. When orally administered 1 day before the injection of adjuvant, the methanol extract of Curcuma phaeocaulis significantly inhibited paw swelling and the serum haptoglobin concentration in adjuvant arthritis mice. Also when orally administered 1 day after the injection of adjuvant, the methanol extract of Curcuma phaeocaulis significantly inhibited paw swelling. Other Curcuma species (Curcuma longa, Curcuma wenyujin, Curcuma kwangsiensis, Curcuma zedoaria and Curcuma aromatica had no significant inhibitory effects on adjuvant-induced paw swelling. Cyclooxygenase (COX-2 activity was significantly inhibited by the methanol extract of C. phaeocaulis. Curcuminoids' (curcumin, bis-demethoxycurcumin and demethoxycurcumin were rich in C. longa, but less in C. phaeocaulis and C. aromatica, not in C. wenyujin, C. kwangsiensis and C. zedoaria, suggesting that curcuminoids' contents do not relate to inhibition of arthritis swelling. Therefore, C. phaeocaulis may be a useful drug among Curcuma species for acute inflammation, and the active constituents of C. phaeocaulis are not curcuminoids.

    This research was conducted to investigate the effects of gamma irradiation on medicinal plants by studying the characteristics of the essential oils of these samples. The samples studied were ''temu lawak'' (Curcuma xanthoriza), ''temu hitam'' (Curcuma aeruginosa), turmeric (Curcuma domestica) and galanga (Kaemferia galanga). The sliced tubers, which contained 8 to 14% of moisture were packed in low density polyethylene bags of 0.13 mm thickness, then irradiated with doses of 0, 5 and 10 kGy. Some samples were directly analyzed and the rest were stored for six months at temperatures of 29±2 0 C and under 70 to 95% humidity. The results showed that the water activity (Aw), the content and characteristics of essential oils, analyzed on a gas liquid chromatography, were not changed by irradiation and storage, but the water content was changed by storage. It was observed also that after irradiation and storage mould and bacteria contents decreased. (author)

    Curcuma oil (C. oil) isolated from turmeric (Curcuma longa L.) has been shown to have neuro-protective, anti-cancer, antioxidant and anti-hyperlipidaemic effects in experimental animal models. However, its effect in insulin resistant animals remains unclear. The present study was carried out to investigate the disease modifying potential and underlying mechanisms of the C. oil in animal models of diet induced insulin resistance and associated thrombotic complications. Male Golden Syrian hamsters on high fructose diet (HFr) for 12 wk were treated orally with vehicle, fenofibrate (30 mg/kg) or C. oil (300 mg/kg) in the last four weeks. Wistar rats fed HFr for 12 wk were treated orally with C. oil (300 mg/kg) in the last two weeks. To examine the protective effect of C. oil, blood glucose, serum insulin, platelet aggregation, thrombosis and inflammatory markers were assessed in these animals. Animals fed with HFr diet for 12 wk demonstrated hyperlipidaemia, hyperglycaemia, hyperinsulinaemia, alteration in insulin sensitivity indices, increased lipid peroxidation, inflammation, endothelial dysfunction, platelet free radical generation, tyrosine phosphorylation, aggregation, adhesion and intravascular thrombosis. Curcuma oil treatment for the last four weeks in hamsters ameliorated HFr-induced hyperlipidaemia, hyperglycaemia, insulin resistance, oxidative stress, inflammation, endothelial dysfunction, platelet activation, and thrombosis. In HFr fed hamsters, the effect of C. oil at 300 mg/kg [ ] was comparable with the standard drug fenofibrate. Curcuma oil treatment in the last two weeks in rats ameliorated HFr-induced hyperglycaemia and hyperinsulinaemia by modulating hepatic expression of sterol regulatory element binding protein 1c (SREBP-1c), peroxisome proliferator-activated receptor-gamma co-activator 1 (PGC-1)α and PGC-1β genes known to be involved in lipid and glucose metabolism.

    Inflammatory bowel disease (IBD) comprising of ulcerative colitis (UC) and Crohn's disease (CD) is a major ailment affecting the small and large bowel. In clinics, IBD is treated using 5-amninosalicylates, antibiotics, the steroids and immunomodulators. Unfortunately, the long term usages of these agents are associated with undue side effects and compromise the therapeutic advantage. Accordingly, there is a need for novel agents that are effective, acceptable and non toxic to humans. Preclinical studies in experimental animals have shown that curcumin, an active principle of the Indian spice turmeric (Curcuma longa Linn) is effective in preventing or ameliorating UC and inflammation. Over the last few decades there has been increasing interest in the possible role of curcumin in IBD and several studies with various experimental models of IBD have shown it to be effective in mediating the inhibitory effects by scavenging free radicals, increasing antioxidants, influencing multiple signaling pathways, especially the kinases (MAPK, ERK), inhibiting myeloperoxidase, COX-1, COX-2, LOX, TNF-α, IFN-γ, iNOS; inhibiting the transcription factor NF-κB. Clinical studies have also shown that co-administration of curcumin with conventional drugs was effective, to be well-tolerated and treated as a safe medication for maintaining remission, to prevent relapse and improve clinical activity index. Large randomized controlled clinical investigations are required to fully understand the potential of oral curcumin for treating IBD.

    This study investigated the suppressive mechanisms of an extract from bioprocessed Lentinus edodes mycelial liquid culture supplemented with turmeric (bioprocessed Curcuma longa extract [BPCLE]) against murine salmonellosis. The BPLCE extract from the bioprocessed mycelia of the Salmonella Typhimurium into murine RAW 264.7 macrophage cells, elimination of intracellular bacteria, and elevation of inducible nitric oxide synthase expression. Dietary administration of BPCLE activated leukocytes from the mice infected with Salmonella through the intraperitoneal route. The enzyme-linked immunosorbent assay of the cytokines produced by splenocytes from infected mice showed significant increases in the levels of Th1 cytokines, including interleukin (IL)-1β, IL-2, IL-6, and IL-12. Histology showed that dietary administration of BPCLE protected against necrosis of the liver resulting from a sublethal dose of Salmonella. In addition, the treatment (1) extended the lifespan of lethally infected mice, (2) suppressed the invasion of Salmonella into human Caco-2 colorectal adenocarcinoma cells, (3) increased excretion of the bacterium in the feces, (4) suppressed the translocation of the Salmonella to internal organs, and (5) increased total immunoglobulin A in both serum and intestinal fluids. BPCLE protected the mice against salmonellosis via cooperative effects that include the upregulation of the Th1 immune reaction, prevention of translocation of bacteria across the intestinal epithelial cells, and increased immunoglobulin A production in serum and intestinal fluids.

    Various Curcuma rhizomes have been used as medicines or spices in Asia since ancient times. It is very difficult to distinguish them morphologically, especially when they are boiled and dried, which causes misidentification leading to a loss of efficacy. We developed a method for discriminating Curcuma species by intron length polymorphism markers in genes encoding diketide-CoA synthase and curcumin synthase. This method could apply to identification of not only fresh plants but also samples of crude drugs or edible spices. By applying this method to Curcuma specimens and samples, and constructing a dendrogram based on these markers, seven Curcuma species were clearly distinguishable. Moreover, Curcuma longa specimens were geographically distinguishable. On the other hand, Curcuma kwangsiensis (gl type) specimens also showed intraspecies polymorphism, which may have occurred as a result of hybridization with other Curcuma species. The molecular method we developed is a potential tool for global classification of the genus Curcuma. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Curcuminoids, the active principle of Curcuma longa L, is one of the most researched subjects worldwide for its broad-spectrum biological activities. Being traditionally known for their anticancer properties and issues related to bioavailability, the curcuminoids, including diferuloylmethane (curcumin), have gained special attention. Thus, the current study focused on the purity profiling of curcuminoids when extracted by accelerated solvent extraction, which was run with turmeric rhizome powder (20 g) at 1500 psi and at 50°C, with a static time of 10 min and with three cycles. The performance of ethanol, ethyl acetate, and acetone as extraction solvents was comparatively evaluated. Once extracted, the individual curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) were purified by column chromatography, followed by preparative TLC, and the compounds were characterized by spectroscopic and chromatographic techniques. The HPLC method was standardized by using a gradient mobile phase of water and acetonitrile containing 0.1% formic acid. The LODs were calculated as 0.27, 0.33, and 0.42 μg/mL for curcumin, demethoxycurcumin, and bisdemethoxycurcumin, respectively. Accuracy (relative percentage error) and precision RSD values of the developed HPLC method were below 5%. The intraday accuracy ranged between -0.9 and -3.63%. The physical yield was the highest in ethanol (8.4%) extraction, followed by ethyl acetate (7.4%) and acetone (6.6%). Maximum purity was recorded in acetone (46.2%), followed by ethanol (43.4%) and ethyl acetate (38.8%), with no significant differences across the individual curcuminoids. This research will be useful for future applications related to the extraction of curcuminoids at a commercial level and to their profiling in food matrixes.

    Gingivitis affects an estimated 80% of the population, and is characterized as the world's most predominant inflammatory periodontal disease. Without intervention, gingivitis can advance to alveolar bone loss. Therefore, the primary goal in patients suffering with gingivitis is to control plaque buildup and soft tissue inflammation. Current guidelines consider chlorhexidine as the gold standard in the prevention and treatment of gingivitis. However, negative side effects of chlorhexidine, including oral mucosal erosion, discoloration of teeth, and bitter taste, provide an opportunity for alternative medications. Turmeric, a commonly used herb, possesses anti-inflammatory, antioxidant, antibacterial, antiviral, and antifungal properties. By virtue of these properties, multiple controlled trials have been performed to investigate the efficacy of turmeric in gingivitis. The aim of this comprehensive review is to summarize and evaluate the evidence on the efficacy of turmeric as compared to chlorhexidine in the prevention and treatment of gingivitis. PubMed, MedLine (Web of Science), and EBSCO (academic search complete) were utilized as primary literature search tools. The following search strategy was used: ((turmeric OR curcumin OR curcuma) AND (gingivitis OR "gum inflammation")). Five reviewed studies show that both turmeric and chlorhexidine significantly decrease plaque index (PI) and gingival index (GI), and can therefore be used in the prevention and treatment of gingivitis. Both chlorhexidine and turmeric can be used as an adjunct to mechanical means in preventing and treating gingivitis. However, trials longer than 21 days with a greater number of patients are necessary to further evaluate the comparison between turmeric and chlorhexidine. Copyright © 2016 Elsevier Ltd.

    2013-01-01

    Background Previous animal studies have shown that Curcuma longa (turmeric) improves liver function. Turmeric may thus be a promising ingredient in functional foods aimed at improving liver function. The purpose of the study is to investigate the hepatoprotective effect of fermented turmeric powder (FTP) on liver function in subjects with elevated alanine transaminase (ALT) levels. Methods A randomised, double-blind, placebo-controlled trial was conducted between November 2010 and April 2012 at the clinical trial center for functional foods of the Chonbuk National University Hospital. The trial included 60 subjects, 20 years old and above, who were diagnosed mild to moderate elevated ALT levels between 40 IU/L and 200 IU/L. Sixty subjects were randomised to receive FTP 3.0 g per day or placebo 3.0 g per day for 12 weeks. The treatment group received two capsules of FTP three times a day after meals, for 12 weeks. The primary efficacy endpoint was change in the ALT levels in the two groups. The secondary efficacy endpoints included its effect on aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), total bilirubin (TB), and lipid profiles. Safety was assessed throughout the study using ongoing laboratory tests. Adverse events (AEs) were also recorded. Results Sixty subjects were randomised in the study (30 into the FTP group, 30 into the placebo group), and among them, twelve subjects were excluded from the analysis for protocol violation, adverse events or consent withdrawal. The two groups did not differ in baseline characteristics. After 12 weeks of treatment, 48 subjects were evaluated. Of the 48 subjects, 26 randomly received FTP capsules and 22 received placebo. The FTP group showed a significant reduction in ALT levels after 12 weeks of treatment compared with the placebo group (p = 0.019). There was also observed that the serum AST levels were significantly reduce in the FTP group than placebo group (p = 0.02). The GGT levels

    Curcuma, a genus of rhizomatous herbaceous species, has been used as a spice, traditional medicine, and natural dye. In this study, the metabolite profile of Curcuma extracts was determined using gas chromatography-time of flight mass spectrometry (GC/TOF MS) and ultrahigh-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF MS) to characterize differences between Curcuma aromatica and Curcuma longa grown on the Jeju-do or Jin-do islands, South Korea. Previous studies have performed primary metabolite profiling of Curcuma species grown in different regions using NMR-based metabolomics. This study focused on profiling of secondary metabolites from the hexane extract of Curcuma species. Principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA) plots showed significant differences between the C. aromatica and C. longa metabolite profiles, whereas geographical location had little effect. A t-test was performed to identify statistically significant metabolites, such as terpenoids. Additionally, targeted profiling using UPLC/Q-TOF MS showed that the concentration of curcuminoids differed depending on the plant origin. Based on these results, a combination of GC- and LC-MS allowed us to analyze curcuminoids and terpenoids, the typical bioactive compounds of Curcuma, which can be used to discriminate Curcuma samples according to species or geographical origin.

    Full Text Available The objective of this study was to evaluate the effects of the inclusion of annato (Bixa orellana L. and turmeric (Turmeric longa L. in layer feeds on live performance, egg quality, and yolk pigmentation and depigmentation time. A number of 144 layers were distributed in a completely randomized experimental design, with four treatments with six replicates of six birds each. In the basal diet, sorghum replaced 50% of corn, and was supplemented or not with natural pigments to composse the following treatments: Control (0% pigments, AS (2.0% annato, TR (2% turmeric and ASTR (1% annato and 1% turmeric. Egg weight (g, egg production (%, egg mass (%, feed intake (g, feed conversion ratio (kg/dz and kg/kg and mortality were evaluated. The following egg quality parameters were evaluated: specific gravity (SG; yolk, albumen, and eggshell percentages, and yolk color. The treatments did not influence layer performance or egg quality parameters, except for egg production and yolk color. The dietary inclusion of 1% turmeric root and 1% annato seed promoted higher egg production. Diets containing annato resulted in more saturated, more intense, and redder yolk color, with increasing pigment deposition after day 10, with maximum values obtained on day 28. Dried turmeric root did not promote good yolk pigmentation, resulting in higher presence of white in the yolk, which was stabilized on day 4. Three days after pigments were withdrawn from the feeds, yolk color faded in the treatments with annato inclusion.

    Chemical compositions, antioxidative, antimicrobial, anti-inflammatory, and cytotoxic activities of essential oils extracted from four common Curcuma species (Curcuma longa, Curcuma phaeocaulis, Curcuma wenyujin, and Curcuma kwangsiensis) rhizomes in P. R. China are comparatively studied. In total, 47, 49, 35, and 30 compounds are identified in C. longa, C. phaeocaulis, C. wenyujin, and C. kwangsiensis essential oils by GC/MS, and their richest compounds are ar-turmerone (21.67%), elemenone (19.41%), curdione (40.23%) and (36.47%), respectively. Moreover, C. kwangsiensis essential oils display the strongest DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity (IC 50 , 3.47 μg/ml), much higher than ascorbic acid (6.50 μg/ml). C. phaeocaulis oils show the best antibacterial activities against Escherichia coli (MIC, 235.54 μg/ml), Pseudomonas aeruginosa (391.31 μg/ml) and Staphylococcus aureus (378.36 μg/ml), while C. wenyujin and C. kwangsiensis oils show optimum activities against Candida albicans (208.61 μg/ml) and Saccharomyces cerevisiae (193.27 μg/ml), respectively. C. phaeocaulis (IC 50 , 4.63 μg/ml) and C. longa essential oils (73.05 μg/ml) have the best cytotoxicity against LNCaP and HepG2, respectively. C. kwangsiensis oils also exhibit the strongest anti-inflammatory activities by remarkably down-regulating expression of COX-2 and TNF-α. Therefore, due to their different chemical compositions and bioactivities, traditional Chinese Curcuma herbs should be differentially served as natural additives for food, pharmaceutical, and cosmetic. © 2017 Wiley-VHCA AG, Zurich, Switzerland.

    Turmeric, a rhizome of Curcumin longa L. is widely used as both a spice and an herbal medicine. The traditional use of turmeric in gastroenterology is mainly based on its choleretic activity. The aim of this study is to determine the effects of turmeric on bile flow (BF) and total bile acids (TBAs) excretion in a bile fistula rat model after acute duodenal administration. A significant dose-dependent enhancement in both BF and TBAs was detected after treatment with the turmeric decoctions which suggested the choleretic activity was bile acid-dependent secretion. In order to direct the active group of compounds, aqueous (AE), ethyl acetate (EtOAc), and petroleum ether (PE) extracts were investigated. The EtOAc and PE extracts showing high effects were purified to locate the active ingredients. Three curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) and 2 sesquiterpenes (bisacurone B and ar-turmerone) were isolated. It was found Bisacurone B was the most potent choleretic ingredient followed by ar-turmerone, bisdemethoxycurcumin demethoxycurcumin, and then curcumin. The amounts of the active ingredients were quantitatively analyzed by high-performance liquid chromatography. The EtOAc and PE extracts had high sesquiterpenes and curcuminoids content, while the AE extract had poor content of sesquiterpenes and curcuminoids which affected neither BF nor TBAs. Based on the results of multiple linear regression analysis, the content of BIS and TUR were dominant factors (P < 0.01) of controlling BL and TBAs in EtOAC and PE extracts. © 2016 Institute of Food Technologists®

    Curcumin is a substance obtained from the root of the turmeric plant, which has the feature of being a yellow or orange pigment. It is also the main component of curry powder commonly used in Asian cuisine. Curcumin, a substance that has had an important place in traditional Indian and Chinese medicines for thousands of years, has been the center of interest for scientific studies especially in the field of cancer treatment for several years. Laboratory studies have presented some favorable results in terms of curcumin's antioxidant, antiinflammatory and anticancer properties in particular. However, since such findings have yet to be confirmed in clinical studies, its effect on humans is not clearly known. Therefore, when its advantages in terms of toxicity, cost and availability as well as the favorable results achieved in laboratory studies are considered, it would not be wrong to say that curcumin is a substance worth being studied. However, for now the most correct approach is to abstain from its use for medical purposes due to lack of adequate reliable evidence obtained from clinical studies, and because of its potential to interfere with other drugs.
