    Glycyrrhiza uralensis and G. glabra, members of the Fabaceae, are medicinally important species that are native to Asia and Europe. Extracts from these plants are widely used as natural sweeteners because of their much greater sweetness than sucrose. In this study, the three complete chloroplast genomes and five 45S nuclear ribosomal (nr)DNA sequences of these two licorice species and an interspecific hybrid are presented. The chloroplast genomes of G. glabra, G. uralensis and G. glabra × G. uralensis were 127,895 bp, 127,716 bp and 127,939 bp, respectively. The three chloroplast genomes harbored 110 annotated genes, including 76 protein-coding genes, 30 tRNA genes and 4 rRNA genes. The 45S nrDNA sequences were either 5,947 or 5,948 bp in length. Glycyrrhiza glabra and G. glabra × G. uralensis showed two types of nrDNA, while G. uralensis contained a single type. The complete 45S nrDNA sequence unit contains 18S rRNA, ITS1, 5.8S rRNA, ITS2 and 26S rRNA. We identified simple sequence repeat and tandem repeat sequences. We also developed four reliable markers for analysis of Glycyrrhiza diversity authentication.

    The biotransformation of β-artemether (1) by cell suspension cultures of Glycyrrhiza glabra and Lavandula officinalis is reported here for the first time. The major biotransformed product appeared as a grayish-blue color spot on thin-layer chromatography (TLC) with transparent crystal-like texture. Based on its infrared (IR) and (1)H nuclear magnetic resonance (NMR) spectra, the product was characterized as a tetrahydrofuran (THF)-acetate derivative (2). The highest conversion efficiencies of 57 and 60% were obtained when 8-9-day-old cell suspensions of G. glabra and L. officinalis were respectively fed with 4-7 mg of compound 1 in 40 ml of medium per culture and the cells were harvested after 2-5 days of incubation. The addition of compound 1 at the beginning of the culture cycle caused severe growth depression in a dose-dependent manner, resulting in poor bioconversion efficiency of ~25% at 2-5 mg/culture dose only.

    Medicinal plants have been founded as traditional herbal medicine worldwide. Most of the plant's therapeutic properties are due to the presence of secondary metabolites such as alkaloids, glycosides, tannins and volatile oil. The present investigation analyzed the High-Pressure Liquid Chromatography (HPLC) fractions of Glycyrrhiza glabra (Aqueous, Chloroform, Ethanol and Hexane) against multidrug resistant human bacterial pathogens (Escherichia coli, Acinetobacter baumannii, Staphylococcus aureus and Pseudomonas aeruginosa). All the fractions showed antibacterial activity, were subjected to LC MS/MS analysis for identification of bioactive compounds. Among total HPLC fractions of G. glabra (n = 20), three HPLC fractions showed potential activity against multidrug resistant (MDR) bacterial isolates. Fraction 1 (F1) of aqueous extracts, showed activity against A. baumannii (15 ± 0.5 mm). F4 from hexane extract of G. glabra showed activity against S. aureus (10 ± 0.2 mm). However, F2 from ethanol extract exhibited activity against S. aureus (10 ± 0.3 mm). These active fractions were further processed by LC MS/MS analysis for the identification of compounds. Ellagic acid was identified in the F1 of aqueous extract while 6-aldehydo-isoophiopogonone was present in F4 of hexane extract. Similarly, Liquirtigenin was identified in F2 of ethanol. Glycyrrhiza glabra extracts HPLC fractions showed anti-MDR activity. Three bioactive compounds were identified in the study. 6-aldehydo-isoophiopogonone and Liquirtigenin were for the first time reported in G. glabra. Further characterization of the identified compounds will be helpful for possible therapeutic uses against infectious diseases caused by multidrug resistant bacteria.

This study investigates the G. glabra methanol extract and glycyrrhizin for the treatment of corneal neovascularization (CNV. G. glabra was extracted in 70% aqueous methanol. Phytochemical tests, thin layer chromatography (TLC, and high performance liquid chromatography (HPLC were used for the analysis of chemical composition. The topical solution of G. glabra methanol extract (2% w/v and glycyrrhizin (1% w/v was prepared in normal saline. After corneal burn (1 N NaOH, animals were left untreated for a week so that neovascularization appears in all groups. Treatments started on day 7 and continued for next 21 consecutive days. The animals were treated with 3 drops of various topical solutions thrice a day. Digital photograph analysis and histological studies were used for the evaluation of CNV. Phytochemical analysis of the G. glabra methanol extract showed the presence of saponins, phenols, carbohydrates, flavonoids, and proteins. TLC and HPLC confirmed the presence of glycyrrhizin. Photograph analysis of the extract and glycyrrhizin treated group showed a considerable decrease in CNV. Histological study of G. glabra and glycyrrhizin treated groups showed no blood vessels with properly arranged collagen fibers. This study showed that G. glabra and glycyrrhizin can be used for the treatment of CNV. Bioassay guided isolation can lead to preparation of ophthalmic solutions for the treatment of CNV.

    Full Text Available This study compared the total flavonoid content of Glycyrrhiza glabra L. leaf and root extracts. Results suggested that the total flavonoid content in the leaf extract was obviously higher than that in the root extract. Pinocembrin, the main compound in the leaf extract after purification by column chromatography, showed good antioxidant activity and nitrite scavenging capacity, but moderate inhibitory effect on mushroom tyrosinase. Liquiritin was the main compound in root extract and possessed strong inhibitory effect on mushroom tyrosinase. Both compounds exhibited significant protection effect on H2O2-injured PC12 cells at a low concentration. These results indicate that Glycyrrhiza glabra L. leaf is potential as an important raw material for functional food.

    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.

    In this research work, four different growth stages of Glycyrrhiza Glabra were studied separately and under green house conditions, and in all of these stages the plants were treated by labelled herbicides 14 C-2,4-D and 14 C-Glyphosate through the ad axial surface with activity of 0.60μci up to 0.1018 μci (in each 10μLi of solution). The plants were harvested 72 hours after treatment. They were divided into treated leaf, leaves and stem above the treated leaf and leaves and stem below the treated leaf and root. The amount of radio labelled herbicides in each homo genus solution (produced from extraction of herbicides from plants samples) was quantified using liquid scintillation counter. The amount of herbicide mobility and transfer to different parts of Glycyrrhiza Glabra in each growth stage were determined. This study shows that the best application time of 2,4-D for translocation to the root system of the plant is at 6- leaf stage, and 2,4-D indicates more trans loc ability as compared with Glyphosate

    Full Text Available The aim of this paper is to investigate the removal of toluene from gaseous solution through Glycyrrhiza glabra root (GGR as a waste material. The batch adsorption experiments were conducted at various conditions including contact time, adsorbate concentration, humidity, and temperature. The adsorption capacity was increased by raising the sorbent humidity up to 50 percent. The adsorption of toluene was also increased over contact time by 12 h when the sorbent was saturated. The pseudo-second-order kinetic model and Freundlich model fitted the adsorption data better than other kinetic and isotherm models, respectively. The Dubinin-Radushkevich (D-R isotherm also showed that the sorption by GGR was physical in nature. The results of the thermodynamic analysis illustrated that the adsorption process is exothermic. GGR as a novel adsorbent has not previously been used for the adsorption of pollutants.

    Full Text Available In this study, the antimicrobial and antioxidant activities of root methanolic extracts of Glycyrrhiza glabra var. glandulifera (Waldst. & Kit. Boiss. (Fabaceae were investigated. Plant samples were collected from different habitats in the East Mediterranean part of Turkey. The plant extracts were evaluated for antimicrobial activities against nine bacterial and two yeast strains using disc-diffusion and minimum inhibitory concentration methods. The antioxidant activity was determined by using the DPPH (1,1-diphenyl-2-picrylhydrazyl method. The antimicrobial assays indicated that the plant root extracts were more effective against Gram-positive bacteria than against Gram-negative ones. In addition, the extracts had higher antimicrobial effect against Candida species than against bacteria. The extracts showed good antioxidant activity, with a median inhibitory concentration (IC50 in the range of 588 ± 0.86 µg/mL to 2190 ± 1.73 µg/mL. Results indicated that different environmental conditions in each habitat might affect the contents of chemical compounds and biological activity in the natural licorice populations of. This study also supported the traditional use of licorice and as well as suggested that it may also be its beneficial role in the treatment of other infections. The obtained results indicated that different environmental conditions in each habitat might affect the contents of chemical compounds and the biological activity in the natural licorice populations.

    Liquid chromatography electrospray mass spectrometry (LC-ESI/MS) has been applied to the full characterization of saponins and phenolics in hydroalcoholic extracts of roots of liquorice (Glycyrrhiza glabra). Relative quantitative analyses of the samples with respect to the phenolic constituents and to a group of saponins related to glycyrrhizic acid were performed using LC-ESI/MS. For the saponin constituents, full scan LC-MS/MS fragmentation of the protonated (positive ion mode) or deprotonated (negative ion mode) molecular species generated diagnostic fragment ions that provided information concerning the triterpene skeleton and the number and nature of the substituents. On the basis of the specific fragmentation of glycyrrhizic acid, an LC-MS/MS method was developed in order to quantify the analyte in the liquorice root samples. Chinese G. glabra roots contained the highest levels of glycyrrhizic acid, followed by those from Italy (Calabria). Copyright © 2010 Elsevier B.V. All rights reserved.

    In this study, antimicrobial activities of an ethanol extract of Tribulus terrestris aloneand in combination with Capsella bursa-pastoris and Glycyrrhiza glabra were examined in vitro against six pathogens namely Streptococcus mutans, Streptococcus sanguis, Actinomyces viscosus, Enterococcus faecalis Staphylococcus aureus, and Escherichia coli. Antibacterial activities of the extracts were examined using disc and well diffusion methods and the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of ethanol extracts were determined against these microorganisms using agar and broth dilution methods. Chlorhexidine was used as positive control. Tribulus terrestris extract exhibited good antibacterial activity against all bacteria. Antibacterial activity of mixed extract was evaluated and exhibited that mixed extract was more effective against all bacteria than any of the cases alone which indicates the synergistic effect between these three extracts (p˂0.05). No strain showed resistance against these extracts. In agar dilution, Tribulus terrestris exhibited MIC values ranging from 35.0 to 20.0 mg/ml and mixed extract showed MIC values ranging from 12.5 to 5.0 mg/ml. The results of broth dilution method were consistent with the findings of the agar dilution method. This in-vitro study was a preliminary evaluation of antibacterial activity of the plants. It provided scientific evidence to support uses of T. terrestris and its mixture with C. bursa-pastoris and G. glabra for the treatment of oral infections. In-vivo studies are also required to better evaluate the effect of these extracts.

    Licorice ( Glycyrrhiza glabra ) is an important medicinal crop often used as health foods or medicine worldwide. The molecular genetics of licorice is under scarce owing to lack of molecular markers. Here, we have developed cleaved amplified polymorphic sequence (CAPS) and high-resolution melting (HRM) markers based on single nucleotide polymorphisms (SNP) by comparing the chloroplast genomes of two Glycyrrhiza species ( G. glabra and G. lepidota ). The CAPS and HRM markers were tested for diversity analysis with 24 Glycyrrhiza accessions. The restriction profiles generated with CAPS markers classified the accessions (2-4 genotypes) and melting curves (2-3) were obtained from the HRM markers. The number of alleles and major allele frequency were 2-6 and 0.31-0.92, respectively. The genetic distance and polymorphism information content values were 0.16-0.76 and 0.15-0.72, respectively. The phylogenetic relationships among the 24 accessions were estimated using a dendrogram, which classified them into four clades. Except clade III, the remaining three clades included the same species, confirming interspecies genetic correlation. These 18 CAPS and HRM markers might be helpful for genetic diversity assessment and rapid identification of licorice species.

    2014-01-01

    Background Rhaponticum cathamoides (RC) is an endemic wild Siberian herb with marked medicinal properties that are still poorly understood. The aim of this study is to investigate the therapeutic potential of RC extract (ERC) compared to the effects of Glycyrrhiza glabra (EGG) and Punica granatum extracts (EPG) in a rat model with high-fat diet-(HFD)-induced signs of metabolic syndrome; therefore, this study addresses a significant global public health problem. Methods Six-month-old male Wistar Albino Glaxo rats were subjected to eight weeks of a standard diet (SD), HFD, or HFD in which ERC, EGG, or EPG powders were incorporated at 300 mg/kg/day. The serum lipid profile, corticosterone and cytokine concentrations, glucose tolerance, systolic blood pressure, triacylglycerol accumulation, and PPARα DNA-binding activities in the liver samples were determined. Results In contrast to EGG and EPG, an ERC supplement significantly reduced the weight of epididymal tissue (19.0%, p < 0.01) and basal serum glucose level (19.4%, p < 0.05). ERC improved glucose intolerance as well as dyslipidemia more efficiently than EGG and EPG. EGG but not ERC or EPG supplementation decreased systolic blood pressure by 12.0% (p < 0.05). All of the tested extracts reduced serum IL6 and corticosterone levels induced by HFD. However, the lowering effects of ERC consumption on the serum TNF-α level and its restoring effect on the adrenal corticosterone level significantly exceeded the improvements induced by EGG and EPG. ERC intake also reduced triacylglycerol accumulation and increased the PPARα DNA-binding activity in the liver more significantly than EGG and EPG. Conclusions ERC powder supplementation improved glucose and lipid metabolism more significantly than EGG and EPG in rats fed on HFD, supporting the strategy of R. carthamoides use for safe relief of metabolic syndrome and its related disturbances such as inflammation, stress, and hepatic steatosis.

    Full Text Available Objectives: About two-thirds of cancer patients undergo radiotherapy. Oral mucositis represents a major complication of radiotherapy, causing morbidity and mortality and decreasing the quality of life of patients. This study aimed to assess the preventive effect of Glycyrrhiza aqueous extract on oral mucositis in cancer patients under head and neck radiotherapy.Materials and Methods: In this double-blind clinical trial, 37 head and neck cancer patients were divided into intervention (n=19 group receiving Glycyrrhiza aqueous extract and control (n=18 group receiving placebo. Patients in the test group used Glycyrrhiza aqueous extract topically twice a day from the first day of starting radiotherapy until the end of the second week. Patients were examined in the first day of radiotherapy for any type of wound before treatment and those with oral ulcers before radiotherapy were excluded from the study. The grade of mucositis was determined using the classification by the World Health Organization. ANCOVA was performed to assess any difference between the two groups with regard to oral mucosal irritation and wound size after the intervention while controlling for the covariates such as sex and age.Results: Significant differences were found in the maximum grade of mucositis and oral mucosal irritation between the intervention and control groups (P<0.001.Conclusions: This study showed that aqueous extract of Glycyrrhiza can be effective for decreasing the severity of oral mucositis in head and neck cancer patients undergoing radiotherapy.

    The use of doxorubicin (DOX) is limited by its dose-dependent cardio toxicity in which reactive Oxygen Species (ROS) play an important role in the pathological process. The aim of this study was to evaluate the protective effect of three medicinal plants, Nigella sativa (N), Glycyrrhiza glabra (G) and Zingiber officinale (Z), and their combination (NGZ), against DOX-induced apoptosis and death in H9c2 cells. The cells were incubated with different concentrations of each extract or NGZ for 4 hr which continued in the presence or absence of 5µM doxorubicin for 24 hr. Cell viability and the apoptotic rate were determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium (MTT) and propidium iodide (PI) staining assays, respectively. The level of ROS and lipid peroxidation were measured by fluorimetric methods. Treatment with doxorubicin increased ROS generation, enhanced malondialdehyde (MDA) formation, and induced apoptosis. Co-treatment of the cells with each herb extract increased viability of cells dose-dependently with a maximum protection effect of about 30%, and their potencies were N>G>Z. The combination of the threshold dose of each extract (NGZ) produced a similar effect, which was increased dose-dependently to a maximum protection of 70%. These effects were correlated with the effects of NGZ on ROS and MDA. All of the extracts have some protective effects against DOX-induced toxicity in cardiomyocytes with similar efficacies, but with different potencies. However, NGZ produced much higher protective effect via reducing oxidative stress and inhibiting of apoptotic induction processes. Further investigations are needed to determine the effects of NGZ on DOX chemotherapy.

    "Licorice oil extract" (LOE) (antioxidant agent) is described in the notice of Japanese food additive regulations as a material obtained from the roots and/or rhizomes of Glycyrrhiza uralensis, G. inflata or G. glabra. In this study, we aimed to identify the original Glycyrrhiza species of eight food additive products using LC/MS. Glabridin, a characteristic compound in G. glabra, was specifically detected in seven products, and licochalcone A, a characteristic compound in G. inflata, was detected in one product. In addition, Principal Component Analysis (PCA) (a kind of multivariate analysis) using the data of LC/MS or (1)H-NMR analysis was performed. The data of thirty-one samples, including LOE products used as food additives, ethanol extracts of various Glycyrrhiza species and commercially available Glycyrrhiza species-derived products were assessed. Based on the PCA results, the majority of LOE products was confirmed to be derived from G. glabra. This study suggests that PCA using (1)H-NMR analysis data is a simple and useful method to identify the plant species of origin of natural food additive products.

    Full Text Available Leaves, wood, seed, bark and pericarp of the fruit of Pongamia glabra were separately dried, powdered and extracted with methanol in Soxhlet extractor. Anthelmintic activity of these various extracts was evaluatedon Indian adult earthworms, Pherentima posthuma. Results showed that the seed part of P. glabra took less time to cause paralysis and death of the earthworms; therefore, seeds were extracted successively withpetroleum ether, ethyl acetate and methanol in Soxhlet extractor. Again these extracts were screened for anthelmintic activity. Results showed that the ethyl acetate extract of seeds of P. glabra was most potentfollowed by petroleum ether extract. It can be concluded that anthelmintic activity of the seed of P. glabra is due to the active principles present mostly in the ethyl acetate and petroleum ether extracts.

    Full Text Available Nanotechnology is a new discipline with huge applications including medicine and pharmacology industries. Although several methods and reducing agents have been employed to synthesize silver nanoparticles, reactive chemicals promote toxicity and nondesired effects on the human and biological systems. The objective of this work was to synthesize silver nanoparticles from Glycyrrhiza glabra and Amphipterygium adstringens extracts and determine their bactericidal and antimycotic activities against Enterococcus faecalis and Candida albicans growth, respectively. 1 and 10 mM silver nitrate were mixed with an extract of Glycyrrhiza glabra and Amphipterygium adstringens. Green silver nanoparticles (AgNPs were characterized by TEM, Vis-NIR, FTIR, fluorescence, DLS, TGA, and X-ray diffraction (XRD analysis. Bactericidal and antimycotic activities of AgNPs were determined by Kirby and Bauer method and cell viability MTT assays. AgNPs showed a spherical shape and average size of 9 nm if prepared with Glycyrrhiza glabra extract and 3 nm if prepared with Amphipterygium adstringens extract. AgNPs inhibited the bacterial and fungal growth as was expected, without a significant cytotoxic effect on human epithelial cells. Altogether, these results strongly suggest that AgNPs could be an interesting option to control oral biofilms.

    The effectiveness of antimalarial drugs is declining at an ever accelerating rate, with consequent increase in malaria-related morbidity and mortality. The newest antiplasmodial drug from plants is needed to overcome this problem. The aim of this study was to assess antimalarial activity of the ethanolic extracts of 10 different medicinal plants from eight families against Plasmodium falciparum chloroquine-sensitive 3D7 strain. The selection of the hereby studied plants was based on the existing information on their local ethnobotanic history. Plants were dried, powdered, and macerated in a hydroalcoholic solution. Resulting extracts have been assessed for in vitro and in vivo antimalarial and brine shrimp toxicity activities. Of 10 plant species tested, four plants: Althea officinalis L. (Malvaceae), Myrtus communis Linn (Myrtaceae), Plantago major (Plantaginaceae), and Glycyrrhiza glabra L. (Papilionaceae) displayed promising antimalarial activity in vitro (50% inhibitory concentration values of 62.77, 42.18, 40.00, and 13.56 μg/mL, respectively) with no toxicity against brine shrimp larvae. The crude extracts of three active plants, G. glabra, M. communis, and A. officinalis, also significantly reduced parasitemia in vivo in female Swiss albino mice at a dose of 400 mg/kg compared to no treatment. Antiplasmodial activities of extracts of A. officinalis and M. communis are reported for the first time.

    The extracts of glycyrrhiza, Mentha and Melissa were tested for the antiulcerogenic activities against indomethacin induced ulcer in irradiated rats. Animals were irradiated at radiation dose levels 0.5, 1 and 2 Gy. The extracts were given orally 3 days after irradiation and the antiulcerogenic as well as the antisecretory and cyroprotective effects of the extracts were determined. All plant extracts produced pronounced antiulcerogenic activities and reduced acid output, increased mucin and decreased pepsin secretion in pyloric ligated rats. The antiulcerogenic activity of the plant extracts was also confirmed histologically. The effect of the plant extract could be party due to their flavonoids content and to their free radical scavenging properties. The stomach is a radiosensitive part of the gastriontestinal tract (Friedman, 1992). It does not tolerate radiation doses that are necessary to control cancer. Hoever, some parts of the stomach are often in the primary treatment field in radiotherapy

    Daiokanzoto (DKT), a Kampo medicine that includes the combination of two crude drugs (rhubarb and glycyrrhiza), is clinically effective for constipation. The aim of this study is to clarify the influence of glycyrrhiza, three glycyrrhiza constituents (glycyrrhizin, liquiritin, and liquiritin apioside), and eight antibiotics on the purgative action of DKT, rhubarb, or sennoside A, a constituent of rhubarb, in mice. The purgative actions of rhubarb and sennoside A were significantly intensified when glycyrrhiza was co-administered orally to mice. Liquiritin and liquiritin apioside but not glycyrrhizin showed significant amplification of the purgative action in a dose-dependent manner. The purgative actions of DKT and sennoside A were significantly reduced by the pre-administration of ampicillin, cefcapene pivoxil, faropenem, fosfomycin, or kanamycin, but were not affected by the pre-administration of clarithromycin or levofloxacin. On the other hand, the purgative action of sennoside A was significantly reduced by the pre-administration of minocycline, whereas that of DKT was not affected. The effect of minocycline on the purgative action of sennoside A was lost when glycyrrhiza was co-administered. These results suggest that liquiritin and liquiritin apioside contribute as active substances for the purgative action of DKT, and some antibiotics reduce the purgative action of DKT and sennoside A. Furthermore, glycyrrhiza has the ability to recover the purgative action of sennoside A suppressed by minocycline via an unknown mechanism.

    The increased cancer risk associated with hormone therapies has encouraged many women to seek non-hormonal alternatives including botanical supplements such as hops (Humulus lupulus) and licorice (Glycyrrhiza spec.) to manage menopausal symptoms. Previous studies have shown estrogenic properties for hops, likely due to the presence of 8-prenylnarigenin, and chemopreventive effects mainly attributed to xanthohumol. Similarly, a combination of estrogenic and chemopreventive properties has been reported for various Glycyrrhiza species. The major goal of the current study was to evaluate the potential estrogenic effects of three licorice species (Glycyrrhiza glabra, G. uralensis, and G. inflata) in comparison with hops. Extracts of Glycyrrhiza species and spent hops induced estrogen responsive alkaline phosphatase activity in endometrial cancer cells, estrogen responsive element (ERE)-luciferase in MCF-7 cells, and Tff1 mRNA in T47D cells. The estrogenic activity decreased in the order H. lupulus > G. uralensis > G. inflata > G. glabra. Liquiritigenin was found to be the principle phytoestrogen of the licorice extracts; however, it exhibited lower estrogenic effects compared to 8-prenylnaringenin in functional assays. Isoliquiritigenin, the precursor chalcone of liquiritigenin, demonstrated significant estrogenic activities while xanthohumol, a metabolic precursor of 8-prenylnaringenin, was not estrogenic. Liquiritigenin showed ERβ selectivity in competitive binding assay and isoliquiritigenin was equipotent for ER subtypes. The estrogenic activity of isoliquiritigenin could be the result of its cyclization to liquiritigenin under physiological conditions. 8-Prenylnaringenin had nanomolar estrogenic potency without ER selectivity while xanthohumol did not bind ERs. These data demonstrated that Glycyrrhiza species with different contents of liquiritigenin have various levels of estrogenic activities, suggesting the importance of precise labeling of botanical

The rats in Sini Tang group and Sini Tang without Glycyrrhizae Radix et Rhizoma group were treated respectively with physic liquor by intragastric administration at the dose of 0.02 mL•g ⁻¹ (equivalent to 0.8 g•mL ⁻¹ crude drugs) once a day for 7 days. The rats in normal group were given with equal volume of saline solution. The plasma samples were collected from each rat 0.5 h after the last administration for GC-MS detection. The data was used for multivariate statistical analysis to obtain 14 potential metabolic markers(13 of them were identified). Then their relative content and metabolic pathways were analyzed. Compared with Sini Tang without Glycyrrhizae Radix et Rhizoma group, seven metabolic markers of were reduced in Sini Tang group. Analysis on physiological functions of these potential metabolic markers showed that the Glycyrrhizae Radix et Rhizoma in Sini Tang could reduce the toxicity of Aconiti Lateralis Radix Preparata by adjusting the glycolysis, lipid metabolism, citrate cycle and some amino acids metabolism.

    Antimutagenesis against N-nitroso compounds contribute to prevention of human cancer. We have found that Glycyrrhiza aspera ethanolic extract exhibits antimutagenic activity against N-methyl-N-nitrosourea (MNU) using the Ames assay with Salmonella typhimurium TA1535. In the present study, eight purified components from Glycyrrhiza, namely glabridin, glycyrrhetinic acid, glycyrrhizin, licochalcone A, licoricesaponin H2, licoricesaponin G2, liquiritigenin and liquiritin were evaluated for their antimutagenicity against MNU in the Ames assay with S. typhimurium TA1535. Glycyrrhetinic acid, glycyrrhizin, licoricesaponin G2, licoricesaponin H2 and liquiritin did not show the antimutagenicity against MNU in S. typhimurium TA1535. Glabridin, licochalcone A and liquiritigenin reduced revertant colonies derived from MNU in S. typhimurium TA1535 without showing cytotoxic effects, indicating that these compounds possess antimutagenic activity against MNU. The inhibitory activity of glabridin and licochalcone A was more effective than that of liquiritigenin. Thus, Glycyrrhiza contains antimutagenic components against DNA alkylating, direct-acting carcinogens.

    The Bougainvillea glabra bract was extracted using three ratios of methanolic solvents at 50%, 70% and 100%. In this study, the methanolic extracts of B. glabra bract were evaluated for antioxidant properties and quantification of phenolics and flavanoids. Methanol at 100% was the highest extraction efficiency among three other methanolic with yield value of 38%. The content of phenolics and flavonoids of B. glabra bracts in methanol 100% were 63.92±0.90 GAE mg/100g and 249.53±26.20 QE mg/100g respectively. The antioxidant activity was measured using three different bioassays namely, DPPH, ABTS and FRAP. The results were expressed as mg Trolox equivalent per 100 g where Trolox is a vitamin E analog. Among these methanol extracts, highest antioxidant capacity was observed in the pure methanol concentration. Positive correlation was observed in B. glabra bract between DPPH assay and TPC, r2=1.00. The methanol extract at 100% was rich in polyphenolics, which indicating that the B. glabra bract has the potential to be recommended as a good dietary source of natural antioxidants.

    Sarcandra glabra (Chinese name, Zhongjiefeng) is an important herb widely used in traditional Chinese medicine. Lycopene has been shown to be a powerful antioxidant. This study aims to test the hypothesis that Sarcandra glabra combined with lycopene protect rats from lipopolysaccharide (LPS) induced acute lung injury (ALI). Metabolomics approach combined with pathological inspection, serum biochemistry examination, enzyme-linked immunosorbent assay and western blotting were used to explore the protective effects of Sarcandra glabra and lycopene on LPS-induced ALI, and to elucidate the underlying mechanisms. Results showed that Sarcandra glabra and lycopene could significantly ameliorate LPS-induced histopathological injuries, improve the anti-oxidative activities of rats, decrease the levels of TNF-α and IL-6, suppress the activations of MAPK and transcription factor NF-κB and reverse the disturbed metabolism towards the normal status. Taken together, this integrated study revealed that Sarcandra glabra combined with lycopene had great potential in protecting rats from LPS-induced ALI, which would be helpful to guide the clinical medication.

    Waldheimia glabra (Decne.) Regel is a wild plant from the Himalayan Mountains, commonly known as Smooth Ground Daisy. This plant is traditionally used by local populations in religious rituals (incense) or in traditional herbal medicine to treat skin diseases, headache, joint pain and fever. In literature few data are available on the investigation of this aromatic plant. The present work aims at deepening knowledge about the chemical composition of W. glabra extracts and incense, as well as its activity on TRP ion channels. Extracts and incense of W. glabra were analyzed by using HS-SPME GC/MS, GC/MS and NMR analysis. Tests on the activity of W. glabra extracts and isolated compounds (+)-ludartin 1 and B-ring-homo-tonghaosu 2 on TRP channels were also performed. Some extracts and pure compounds from W. glabra showed an interesting activity in terms of efficacy and potency on rat TRPA1, an ion channel involved in several sensory mechanisms, including pungency, environmental irritation and pain perception. Activity is discussed and compared with that of other known TRPA1 natural agonists with different chemical structures. All compounds showed only a negligible inhibition activity on rat TRPM8 ion channel. Our findings demonstrate that W. glabra is involved in the receptor activation mechanism and therefore represents a new natural product potentially useful in pharmaceutical and agrifood research.

    The radices of Glycyrrhiza uralensis Fisch. and herbal preparations containing Glycyrrhiza spp. have been used for thousands of years as an herbal medicine for the treatment of viral induced cough, viral hepatitis, and viral skin diseases like ulcers in China. Glycyrrhizic acid (GA) is considered the principal component in Glycyrrhiza spp. with a wide spectrum of antiviral activity. The present study attempt to validate the medicinal use of Glycyrrhiza uralensis for hand, foot and mouth disease (HFMD) and further to verify whether GA is an active antiviral component in the water extract of Glycyrrhiza uralensis. Radices of Glycyrrhiza uralensis Fisch. were extracted with hot water. The chemical contents of the extract were profiled with HPLC analysis. The antiviral activity of the extract and the major components was evaluated against infection of enterovirus 71 (EV71) and coxsackievirus A16 (CVA16) on Vero cells. The cytopathic effect caused by the infection was measured with MTT assay. Infectious virion production was determined using secondary infection assays and viral protein expression by immunoblotting analysis. The extract at 1000 μg/ml suppressed EV71 replication by 1.0 log and CVA16 by 1.5 logs. The antiviral activity was associated with the content of GA in the extract since selective depletion of GA from the extract by acid precipitation resulted in loss of antiviral activity. In contrast, the acid precipitant retained antiviral activity. The precipitant at a concentration of 200 μg/ml inhibited EV71 and CVA16 replication by 1.7 and 2.2 logs, respectively. Furthermore, GA dose-dependently blocked viral replication of EV71 and CVA16. At 3 mM, GA reduced infectious CVA16 and EV71 production by 3.5 and 2.2 logs, respectively. At 5mM, CVA16 production was reduced by 6.0 logs and EV71 by 4.0 logs. Both EV71 and CVA16 are members of Enterovirus genus, time-of-drug addition studies however showed that GA directly inactivated CVA16, while GA anti-EV71 effect

    This study was aimed at investigating the antioxidant activity of Mangifera indica Linn., Cocos nucifera Linn., and Averrhoa carambola Linn. and their biological effect on human keratinocytes affected by the ultraviolet B (UVB), a major cause of cell damage and skin cancer through induction of DNA damage, production of reactive oxygen species (ROS), and apoptosis. The richest antioxidant activity was found in ethanol fraction of M. indica (21.32 ± 0.66 mg QE/g dry weight), while the lowest one was found in aqueous fractions of M. indica and C. nucifera (1.76 ± 2.10 and 1.65 ± 0.38 mg QE/g dry weight, respectively). Ethanol and aqueous fractions of A. carambola (250 µg/mL) significantly reduced the number of apoptotic cells. The expression of cleaved caspase 3 in UVB-treated group was significantly greater than that in untreated group. Both fractions of A. carambola (50, 100, and 250 µg/mL) significantly decreased the expression of cleaved caspase 3. Regarding the induction of DNA repair, ethanol (100 and 250 µg/mL) and aqueous (50, 100 and 250 µg/mL) fractions of A. carambola significantly decreased the percentage of cyclobutane pyrimidine dimers (CPD). Taken together, our results suggest that both fractions of A. carambola may be potentially developed for dermal applications. PMID:27057195

    Full Text Available This work focused on the intensification of extraction process of glycyrrhizic acid (GA from Glycyrrhiza uralensis using ultrasound-assisted extraction (UAE method. Various process parameters such as ultrasonic power, ultrasonic frequency, extraction temperature, and extraction time which affect the extraction yield were optimized. The results showed that all process parameters had exhibited significant influences on the GA extraction. The highest GA yield of 217.7 mg/g was obtained at optimized parameters of 125 W, 55 kHz, 25 °C, and 10 min. Furthermore, the extraction kinetics model of this process was also investigated based on Fick’s first law available in the literature. Kinetic parameters such as equilibrium concentration (Ce and integrated influence coefficient (λ for different ultrasonic powers, ultrasonic frequencies, and extraction temperatures were predicted. Model validations were done successfully with the average of relative deviation between 0.96% and 4.36% by plotting experimental and predicted values of concentration of GA in extract. This indicated that the developed extraction model could reflect the effectiveness of the extraction of GA from Glycyrrhiza uralensis and therefore serve as the guide for comprehending other UAE process.

    The chemical composition of essential oil obtained by hydrodistillation of the leaves of Pachira glabra Pasq., (PgEO) has been studied by Gas Chromatography (GC) and Gas Chromatography coupled with Mass Spectrometry (GC/MS). Thirty three constituents representing 98.4% of total contents were identified from the essential oil. The major constituents of oil were limonene (23.2%), β-caryophyllene (14.5%), phtyol (8.5%) and β-bisabolene (6.3%). The antimicrobial activity of the PgEO was evaluated against a panel of ten bacteria and three fungal strain using agar diffusion and broth microdilution methods. Results have shown that the PgEO exhibited moderate to strong antimicrobial activity against the tested microorganisms except Citrobacter youagae, Micrococcus spp. and Proteus spp. The activity zones of inhibition (ZI) and minimum inhibitory concentrations (MIC) ranged between 13.7 mm-24.0 mm and 0.3 mg/mL-2.5 mg/mL, respectively. The insecticidal activity of PgEO was assayed against the adult Sitophilus zeamais. The lethal concentrations (LC50 and LC90) of the PgEO showed it to be toxic against adult S. zeamais at 32.2 and 53.7 mg/mL, respectively. This is the first report on the chemical composition and in vitro biological activities of essential oil of P. glabra growing in Nigeria.

    Full Text Available The rhizome of Smilax glabra has been used for a long time as both food and folk medicine in many countries. The present study focused on the active constituents from the rhizome of S. glabra, which possess potential anti-inflammatory activities. As a result, nine known compounds were isolated from the rhizome of S. glabra with the bioassay-guiding, and were identified as syringaresinol (1, lasiodiplodin (2, de-O-methyllasiodiplodin (3, syringic acid (4, 1,4-bis(4-hydroxy-3,5-dimethoxyphenyl-2,3-bis(hydroxymethyl-1,4-butanediol (5, lyoniresinol (6, trans-resveratrol (7, trans-caffeic acid methyl ester (8, and dihydrokaempferol (9. Among these compounds, 2 and 3 were isolated for the first time from S. glabra. In addition, the potential anti-inflammatory activities of the isolated compounds were evaluated in vitro in lipopolysaccharide- (LPS- induced RAW264.7 cells. Results indicated that 4 and 7 showed significant inhibitory effects on NO production of RAW264.7 cells, and 1, 2, 3, and 5 showed moderate suppression effects on induced NO production. 1, 7, and 5 exhibited high inhibitory effects on TNF-α production, with the IC50 values less than 2.3, 4.4, and 16.6 μM, respectively. These findings strongly suggest that compounds 1, 2, 3, 4, 5, 7, and 9 were the potential anti-inflammatory active compositions of S. glabra.

    The use of different plant powders of Ambrosia Maritiama, Origanum Vulgare, Glycyrrhiza Glabra, Matricaria Chamomilla and Nigella sativa for protection of peanuts (shelled or unshelled) and onion from infestation by the almond moth, Ephestia Cautella, showed that G. Glabra caused 100% larval mortality in case of shelled peanut at 0.25 g which leads to zero infestation while 100% larval mortality was occurred also when G.Glabra was used at concentration 1.0 gram in unshelled peanut. In onion, 100% mortality was occurred when powders of G.Glabra and M.Chamomilla were used at concentration 0.5 gram and A.Maritiama at concentration 1.0 gram. The use of different plant powders leads to reduction in percent pupation and percent emergence comparing with the control. Also, the number of eggs laid per female was decreased in females treated with plant powders compared to the control and the concentration 1 gram prevent egg hatching for all plant powders used in shelled or unshelled peanut and onion. The use of LC 3 0 of plant powders beside the doses 100 or 150 Gy of gamma radiation leads to increase in percent mortality and decrease in percent infestation as the dose increase. The use of G.Glabra beside 100 or 150 Gy caused 100% mortality and prevent peanut inside shells from infestation, but the plant powders of A.Maritiama, N.Sativa and M.Chamomilla leads to the same result but with the dose 150 Gy. The use of LC 3 0 of plant powders beside 150 Gy leads to decrease in number of eggs and prevent egg hatching in peanut and onion except when N.sativa and M.Chamomilla used with onion

    Dobera glabra (Forssk.) Poir (Salvadoraceae) is a highly valued tree with diverse importance as special mineral sourced feed and a folkloric tool for forecasting droughts. However, there are no reports on its phytochemical and biological investigations. Phytochemical investigation of D. glabra leaves and its protective potential against CCl 4 inducing changes in the genetic materials. D. glabra extract, DGE (70% MeOH/H 2 O), was applied to polyamide column chromatography, eluting with MeOH/H 2 O of decreasing polarities, followed by preparative chromatographic tools, yielded seven compounds. Three DGE doses (50, 100 and 200 mg/kg bw/d) were administrated for 8 weeks intragastrically to male albino rats prior treated with CCl 4 (0.5 mL/kg/bw). The reactive oxygen species (ROS) levels, expression changes of glutamate transporters (GLAST, GLT-1 and SNAT3) mRNA, DNA fragmentation and glutathione peroxidase (GPx) activity were investigated in the liver tissues of these rats. Isorhamnetin-3-O-β-glucopyranoside-7-O-α-rhamnopyranoside, isorhamnetin-3-O-α-rhamnopyranoside-7-O-β-glucopyranoside, kaempferol-3,7-di-O-α-rhamnopyranoside, isorhamnetin-3-O-β-glucopyranoside, kaempferol-3-O-β-glucopyranoside, isorhamnetin and kaempferol were identified. DGE (200 mg/kg bw) + CCl 4 exhibited the most significant reduction in ROS levels and DNA fragmentation with 251.3% and141% compared to 523.1% and 273.2% for CCl 4 , respectively. Additionally, it increased significantly the mRNA expression of GLAST, GLT-1 and SNAT3 to 2.16-, 1.72- and 2.09-fold, respectively. Also, GPx activity was increased to 4.8 U/mg protein/min compared to CCl 4 (1.8 U/mg protein/min). Flavonoid constituents, antioxidant effect and genotoxic protection activity of D. glabra were first reported. DGE may be valuable in the treatment and hindrance of hepatic oxidative stress and genotoxicity.

    Objectives: To evaluate the ethanolic and aqueous extracts of Bauhinia variegata Linn. for in vitro antioxidant and antihyperlipidemic activity. Materials and Methods: Ethanolic and aqueous extracts of the stem bark and root of B. variegata Linn. were prepared and assessed for in vitro antioxidant activity by various methods namely total reducing power, scavenging of various free radicals such as 1,2-diphenyl-2-picrylhydrazyl (DPPH), super oxide, nitric oxide, and hydrogen peroxide. The percentage scavenging of various free radicals were compared with standard antioxidants such as ascorbic acid and butylated hydroxyl anisole (BHA). The extracts were also evaluated for antihyperlipidemic activity in Triton WR-1339 (iso-octyl polyoxyethylene phenol)-induced hyperlipidemic albino rats by estimating serum triglyceride, very low density lipids (VLDL), cholesterol, low-density lipids (LDL), and high-density lipid (HDL) levels. Result: Significant antioxidant activity was observed in all the methods, (P < 0.01) for reducing power and (P < 0.001) for scavenging DPPH, super oxide, nitric oxide, and hydrogen peroxide radicals. The extracts showed significant reduction (P < 0.01) in cholesterol at 6 and 24 h and (P < 0.05) at 48 h. There was significant reduction (P < 0.01) in triglyceride level at 6, 24, and 48 h. The VLDL level was also significantly (P < 0.05) reduced from 24 h and maximum reduction (P < 0.01) was seen at 48 h. There was significant increase (P < 0.01) in HDL at 6, 24, and 48 h. Conclusion: From the results, it is evident that alcoholic and aqueous extracts of B. variegata Linn. can effectively decrease plasma cholesterol, triglyceride, LDL, and VLDL and increase plasma HDL levels. In addition, the alcoholic and aqueous extracts have shown significant antioxidant activity. By the virtue of its antioxidant activity, B. variegata Linn. may show antihyperlipidemic activity.

    Full Text Available Background & Objectives. The plan of this work was to study the larvicidal activity of Cassia occidentalis (Linn. against the larvae of Culex quinquefasciatus. These larvae are the most significant vectors. They transmit the parasites and pathogens which cause a deadly disease like filariasis, dengue, yellow fever, malaria, Japanese encephalitis, chikungunya, and so forth, which are considered harmful towards the population in tropic and subtropical regions. Methods. The preliminary laboratory trail was undertaken to determine the efficacy of petroleum ether and N-butanol extract of dried whole plant of Cassia occidentalis (Linn. belonging to the family Caesalpiniaceae at various concentrations against the late third instar larvae of Culex quinquefasciatus by following the WHO guidelines. Results. The results suggest that 100% mortality effect of petroleum ether and N-butanol extract of Cassia occidentalis (Linn. was observed at 200 and 300 ppm (parts per million. The results obviously showed use of plants in insect control as an alternative method for minimizing the noxious effect of some pesticide compounds on the environment. Thus the extract of Cassia occidentalis (Linn. is claimed as more selective and biodegradable agent. Conclusion. This study justified that plant Cassia occidentalis (Linn. has a realistic mortality result for larvae of filarial vector. This is safe to individual and communities against mosquitoes. It is a natural weapon for mosquito control.

    Glycyrrhiza is the dry root and rhizome of the leguminous plant, Glycyrrhiza uralensis Fisch., Glycyrrhiza inflata Bat. or Glycyrrhiza glabra L., which was firstly cited in Shennong's Herbal Classic in Han dynasty and was officially listed in the Chinese Pharmacopoeia, has been widely used in China during the past millennia. Licoflavone is the major component of Glycyrrhiza with anti-ulcer activity. The present study is based on clarifying the anti-ulcer effect of licoflavone, aiming at elucidating the possible molecule mechanisms of its action for treating gastric ulcer rats induced by acetic acid. Rats were divided into 7 groups, and drugs were administered from on the day after the onset of gastric ulcer (day 3) until day 11 of the experiment once daily continuously. The plasma were analyzed by high-performance liquid chromatography combined with time-of-flight mass spectrometry (HPLC/ESI-TOF-MS), significant different metabolites were investigated to explain its therapeutic mechanism. Furthermore, quantitative real time polymerase chain reaction (RT-PCR) analysis was performed to detect the expression of RNA in stomach tissue for verifying the above results. Licoflavone can effectively cure the gastric ulcer, particularly the middle dose group. According to the statistical analysis of the plasma different metabolites from each groups and the expression of genes in tissues, sixteen significant different metabolites, including histamine, tryptophan, arachidonic acid, phingosine-1-phosphate etc., contributing to the treatment of gastric ulcer were discovered and identified. In RT-PCR analysis, the results of the expression of RNA were corresponded with what we discovered. Our study indicated licoflavone plays the role of treating gastric ulcer by regulating inflammation mediators and amino acid metabolism. We demonstrated that metabolomics technology combined with gene technology is a useful tool to search different metabolites and to dissect the potential

    Full Text Available Tabanid females are better known as hematophagous on man and other mammals, and linked to mechanical transmission of parasites. The association between tabanids and reptiles is poorly known, but has been gaining more corroboration through experiments and occasional observation in the tropics. The present study was conducted at a military base (CIGS/BI-2, situated 54 km from Manaus, Amazonas, in a small stream in a clearing (02°45'33"S; 59°51'03"W. Observations were made monthly, from April 1997 to March 1998, during two consecutive days. At the same time, other vertebrate animals were offered, including humans. However in this paper only data obtained on a common caiman, Caiman crocodilus (Linn., and an anaconda, Eunectes murinus (Linn., in diurnal observations from 05:30 a.m. to 18:30 p.m., will be discussed. A total of 254 tabanid specimens were collected, 40 from the anaconda and 214 from the caiman. Four tabanid species were recorded on these two reptiles: Stenotabanus cretatus Fairchild, S. bequaerti Rafael et al., Phaeotabanus nigriflavus (Kröber and Tabanus occidentalis Linn. Diurnal activities showed species-specific patterns. The first three species occurred only in the dry season. T. occidentalis occurred during the whole observation period, and with increased frequency at the end of the dry season. We observed preferences for body area and related behavior of the host. Observations on the attack of tabanids on one dead caiman are also presented.

    Information on the accumulation of metals in plants is reviewed. The authors report some of their investigations of the metal accumulating plants Hybanthus floribundus and Polycarpia glabra. In general, nickel levels in the aerial parts of plants are quite low, however a number of plants have been cited as nickel tolerant. The leaves of the Hybanthus plant have large epidermal cells and ridges of large cells which continue along the leaf stem and on to the main stem of the bush. It was found that nickel could be located in these large cells. The presence of nickel in the ridge cells was confirmed by an electron probe technique using a scanning electron microscope. These same areas showed high concentration of pectins. In studying the Polycarpia species, two zinc complexes were found to accumulate in the flowers and stems. 22 references.

    Raw licorice roots represent heterogeneous materials obtained from mainly three Glycyrrhiza species. G. glabra, G. uralensis, and G. inflata exhibit marked metabolite differences in terms of flavanones (Fs), chalcones (Cs), and other phenolic constituents. The principal objective of this work was to develop complementary chemometric models for the metabolite profiling, classification, and quality control of authenticated licorice. A total of 51 commercial and macroscopically verified samples were DNA authenticated. Principal component analysis and canonical discriminant analysis were performed on 1H NMR spectra and area under the curve values obtained from UHPLC-UV chromatograms, respectively. The developed chemometric models enable the identification and classification of Glycyrrhiza species according to their composition in major Fs, Cs, and species specific phenolic compounds. Further key outcomes demonstrated that DNA authentication combined with chemometric analyses enabled the characterization of mixtures, hybrids, and species outliers. This study provides a new foundation for the botanical and chemical authentication, classification, and metabolomic characterization of crude licorice botanicals and derived materials. Collectively, the proposed methods offer a comprehensive approach for the quality control of licorice as one of the most widely used botanical dietary supplements. PMID:26244884

    Wound healing has being extensively investigated over the world. Healing impairment is caused by many reasons including increasing of free-radicals-mediated damage, delaying in granulation tissue formation, reducing in angiogenesis and decreasing in collagen reorganization. These facts consequently lead to chronic wound healing. Piper betle Linn (Betle) leaves have been folklore used as an ingredient of drugs for cutaneous wound treatment. However, the effect of betle leaf on wound healing is not yet well elucidated. In this study, we aimed to investigate the healing efficacy of methanol leaf extract of Piper betle Linn on proliferation of fibroblast NIH3T3 cells as well as full-thickness burn and excision wounds in swiss mice. Scratch wound healing assays were conducted to examine the effects of betle leaf extract on healing activity of fibroblast cells. Burn and excision wounds on swiss mouse skins were created for investigating the wound healing progress caused by the betle leaf extract. Malondialdehyde (MDA) was also evaluated to examine the products of lipid hydroperoxide (LPO) under conditions of with or without betle leaf extract treatment. The results of this study showed that Piper betle Linn leaf extract in methanol increased proliferation of NIH3T3 cells and promoted wound healing in vitro and in vivo with both burn wound and excision wound models. In addition, this extract significant decreased level of malondialdehyde (MDA) in liver of treated-mice compared with that in non-treated mice. Our results suggest that Piper betle Linn can be used as an ingredient in developing natural origin drugs for treatment of cutaneous wounds.

    Julie B Hebert

    Full Text Available Recently diverged taxa often show discordance in genetic divergence among genomic loci, where some loci show strong divergence and others show none at all. Genetic studies alone cannot distinguish among the possible mechanisms but experimental studies on other aspects of divergence may provide guidance in the inference of causes of observed discordances. In this study, we used no-choice mating trials to test for the presence of reproductive isolation between host races of the leaf-mining fly, Phytomyza glabricola on its two holly host species, Ilex coriacea and I. glabra. These trials inform our effort to determine the cause of significant differences in the degree of divergence of nuclear and mitochondrial loci of flies collected from the two host plants. We present evidence of reproductive isolation between host races in a controlled greenhouse setting: significantly more mate pairs consisting of flies from the same host plant species produced offspring than inter-host mate pairs, which produced no offspring. We also tested whether the presence of the natal or non-natal host plant affects reproductive success. Flies collected from I. coriacea were more likely to produce offspring when in the presence of the natal host, whereas the presence or absence of either the natal or non-natal host had no effect on flies collected from I. glabra. The results indicate discordant patterns of nuclear and mitochondrial divergence among host races of P. glabricola are likely due to incomplete lineage sorting, and the host races may be well on their way to becoming biological species.

However, the effect of human disturbance on such specific interactions and its ecological consequences is poorly understood. This study evaluated the outcomes of mutualism between ants and the EFN-bearing plant Stachytarpheta glabra under anthropogenic disturbance. We compared the arthropod fauna composition between two groups of twenty plant individuals, one in an area disturbed by human activities and one in a preserved area. We also check the plant investment in herbivory defense and the consequential leaf damage by herbivore. Our results indicate that such disturbances cause simplification of the associated fauna and lack of proper ant mutualist. This led to four times more herbivory on plants of disturbed areas, despite the equal amount of EFN and ant visitors and low abundance of herbivores. The high pressure of herbivory may difficult the re-establishment of S. glabra, an important pioneer species in ferruginous fields, therefore it may affect resilience of this fragile ecological community.

    Glycyrrhiza uralensis roots used in this study were produced using novel cultivation systems, including artificial hydroponics and artificial hydroponic-field hybrid cultivation. The equivalency between G. uralensis root extracts produced by hydroponics and/or hybrid cultivation and a commercial Glycyrrhiza crude drug were evaluated for both safety and efficacy, and there were no significant differences in terms of mutagenicity on the Ames tests. The levels of cadmium and mercury in both hydroponic roots and crude drugs were less than the limit of quantitation. Arsenic levels were lower in all hydroponic roots than in the crude drug, whereas mean lead levels in the crude drug were not significantly different from those in the hydroponically cultivated G. uralensis roots. Both hydroponic and hybrid-cultivated root extracts showed antiallergic activities against contact hypersensitivity that were similar to those of the crude drug extracts. These study results suggest that hydroponic and hybrid-cultivated roots are equivalent in safety and efficacy to those of commercial crude drugs. Further studies are necessary before the roots are applicable as replacements for the currently available commercial crude drugs produced from wild plant resources.

    Excellent memory, extraordinary intelligence, great academic achievement, and successful career are the dreams of every individual in this era of competition and professionalism. A good memory power acts as a catalyst in all walks of life, be it academic success or maintenance of personal relationships. It is observed that an average man uses only 10% of his natural memory. Remaining 90% is left unused in a haphazard manner. As per the American psychologist Carl Emil Seashore, if one is alert and makes systematic attempts to awaken and use the natural memory properly, his/her natural memory would be activated creatively and would offer benefits of higher order. A comparative study was conducted comprising 90 subjects to know the efficacy of Medhya Rasayana and Yogic practices in short-term memory of school-going children. The study was conducted over a period of 3 months. It was an open, prospective, and randomized clinical study. The subjects of group A formed the control group and they were observed silently for 3 months without any intervention. The subjects in group B were administered with Choorna (powder) of four Medhya Rasayanas, Mandukaparni (Centella asiatica Linn.), Yashtimadhu (Glycyrrhiza glabra Linn.), Guduchi [Tinospora cordifolia (Willd.) Miers ex Hook. f. and Thoms.], and Sankhapushpi (Convolvulus pluricaulis Choisy), at a dose of 2 g twice daily with milk. Subjects belonging to group C were advocated regular Yogic practices of Asanas, Pranayama, and Dhyana. Further study revealed that among the three groups, group B treated with Medhya Rasayana showed highly significant and most effective changes with respect to objective parameters in the tests, i.e. (1) short-term memory test pictures and (2) serial recall effects test using memory scope. Among the three groups, group C treated with Yogic practices showed highly significant and most effective changes with respect to subjective and objective parameters in mini mental status scale i.e. test 3.

    This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng.) Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS) and the Sandy Strip Closed Shrub (SSCS) formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalariform perforation plates, wood parenchyma scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees may be due to the greater diameters of their branches. Our results suggest that M. glabra develops structural adaptations to the restinga micro-environmental variations during its development.

    Full Text Available Introduction . Dermatitis herpetiformis is a rare bullous disorder. Autoimmunological disturbances associated with hypersensitivity to gluten play the main role in the etiopathogenesis of the disease. Clinical manifestations include polymorphic skin lesions which may cause diagnostic difficulties. Objective. To present a case of dermatitis herpetiformis diagnosed and treated without any clinical improvement as tinea cutis glabrae. Case report . A 20-year-old male patient was admitted for the evaluation of polymorphic skin lesions of 7-month duration distributed symmetrically on the skin of elbows, knees, face and the gluteal and sacral region. The patient was previously treated with systemic and topical antimycotic drugs. Due to a typical distribution of skin lesions as well as symptoms reported by the patient, we started to suspect Duhring’s disease. The diagnosis was confirmed by direct immunofluorescence of skin biopsy and serological tests. Systemic treatment with dapsone and a gluten-free diet led to clinical improvement. Conclusions . The morphology and localization of skin lesions in Duhring’s disease may be similar to the clinical presentation of fungal infection of the skin, which in equivocal cases should be excluded by a mycological test.

    Abutilon indicum (Linn. sweet (Malvaceae commonly called “Country Mallow” is a perennial plant up to 3m in
    height. It is abundantly found as weed in sub-Himalayan tract and in hotter parts of India. The plant is traditionally
    used for treatment of several diseases like bronchitis, body ache, toothache, jaundice, diabetes, fever, piles,
    leprosy, ulcers, cystitis, gonorrhea, diarrhoea etc. Abutilon indicum Linn. is reported to have hepatoprotective,
    hypoglycemic, antimicrobial, male contraceptive and antidiarrhoeal activities. The present study was done to
    evaluate the analgesic potential of various extracts of root of Abutilon indicum Linn. The powdered root (900 g
    was subjected to successive solvent extraction with solvents in increasing order of polarity viz. petroleum ether
    (60-80 C°, methanol and ethanol by soxhlet apparatus for 72 hrs. The marc was extracted by cold maceration for
    72 hrs. to obtain water soluble extract. Peripheral analgesic activity was studied using acetic acid induced writhing
    method in Swiss albino mice (20-30 g while central analgesic activity was evaluated by tail flick method and
    tail immersion method. Results indicated that all the tested extracts except methanol extract exhibited significant
    analgesic activity in both animals’ models. Petroleum ether extract showed higher analgesic activity. The activity
    may be related with central mechanism or due to peripheral analgesic mechanisms. Thus the present study authenticates
    the traditional use.

  15. Identification of Glycyrrhiza as the rikkunshito constituent with the highest antagonistic potential on heterologously expressed 5HT3A receptors due to the action of flavonoids

    Directory of Open Access Journals (Sweden)

    Robin eHerbrechter

    2015-07-01

    Full Text Available The traditional Japanese phytomedicine rikkunshito is traditionally used for the treatment of gastrointestinal motility disorders, cachexia and nausea. These effects indicate 5-HT3 receptor antagonism, due to the involvement of these receptors in such pathophysiological processes. E.g. setrons, specific 5-HT3 receptor antagonists are the strongest antiemetics, developed so far. Therefore, the antagonistic effects of the eight rikkunshito constituents at heterologously expressed 5-HT3A receptors were analyzed using the two-electrode voltage-clamp technique. The results indicate that tinctures from Aurantii, Ginseng, Zingiberis, Atractylodis and Glycyrrhiza inhibited the 5-HT3A receptor response, whereas the tinctures of Poria cocos, Jujubae and Pinellia exhibited no effect. Surprisingly, the strongest antagonism was found for Glycyrrhiza, whereas the Zingiberis tincture, which is considered to be primarily responsible for the effect of rikkunshito, exhibited the weakest antagonist of 5-HT3A receptors. Rikkunshito contains various vanilloids, ginsenosides and flavonoids, a portion of which show an antagonistic effect on 5-HT3 receptors. A screening of the established ingredients of the active rikkunshito constituents and related substances lead to the identification of new antagonists within the class of flavonoids. The flavonoids (--liquiritigenin, glabridin and licochalcone A from Glycyrrhiza species were found to be the most effective inhibitors of the 5-HT-induced currents in the screening. The flavonoids (--liquiritigenin and hesperetin from Aurantii inhibited the receptor response in a non-competitive manner, whereas glabridin and licochalcone A exhibited a potential competitive antagonism. Furthermore, licochalcone A acts as a partial antagonist of 5-HT3A receptors. Thus, this study reveals new 5-HT3A receptor antagonists with the aid of increasing the comprehension of the complex effects of rikkunshito.

    Full Text Available Rhizoma Smilacis glabrae, a traditional Chinese medicine (TCM as well as a functional food, has been commonly used for detoxification treatments, relieving dampness and as a diuretic. In order to quickly define the chemical profiles and control the quality of Smilacis glabrae, ultra high performance liquid chromatography coupled with electrospray ionization hybrid linear trap quadrupole orbitrap mass spectrometry (UHPLC-ESI/LTQ-Orbitrap-MS was applied for simultaneous identification and quantification of its bioactive constituents. A total of 56 compounds, including six new compounds, were identified or tentatively deduced on the basis of their retention behaviors, mass spectra, or by comparison with reference substances and literature data. The identified compounds belonged to flavonoids, phenolic acids and phenylpropanoid glycosides. In addition, an optimized UHPLC-ESI/LTQ-Orbitrap-MS method was established for quantitative determination of six marker compounds from five batches.

    Full Text Available Purpose : Abutilon indicum (Linn. sweet (Malvaceae commonly called ′Country Mallow′ is a perennial plant up to 3 m in height. It is abundantly found as a weed in the sub-Himalayan tract and in the hotter parts of India. The plant is traditionally used for treatment of several diseases like bronchitis, body ache, toothache, jaundice, diabetes, fever, piles, leprosy, ulcers, cystitis, gonorrhea, diarrhea, and so on. Abutilon indicum Linn. is reported to have hepatoprotective, hypoglycemic, antimicrobial, male contraceptive, and antidiarrheal activities. The present study was done to evaluate the analgesic potential of various extracts of the root of Abutilon indicum Linn. Materials and Methods : The powdered root (900 g was subjected to successive solvent extraction, with solvents in increasing order of polarity, namely, petroleum ether (60 - 80΀C, methanol, and ethanol, using the soxhlet apparatus for 72 hours. The marc was extracted by cold maceration for 72 hours, to obtain a water-soluble extract. The peripheral analgesic activity was studied using acetic acid-induced writhing method in Swiss albino mice (20 - 30 g, while the central analgesic activity was evaluated by the tail flick method and the tail immersion method. Results : Results indicated that all the tested extracts, except the methanol extract, exhibited significant analgesic activity in both animals′ models. Petroleum ether extract showed higher analgesic activity. The activity may be related to the central mechanism or may be due to the peripheral analgesic mechanisms. Conclusion : The present study authenticates the traditional use.

    Full Text Available Out of the twenty-four samples of shrimp and fish muscle used for this study, twelve were collected near a large marine sewer for waste disposal, 3 km off the coast of Fortaleza (Brazil and used for the isolation of E. coli. Other twelve were collected at the Mucuripe fresh fish market (Fortaleza, Brazil and used for the isolation of Staphylococcus aureus. Ethanol, water and acetone-diluted extracts of guava and papaya leaf sprouts were tested on the bacteria in order to verify their microbicidal potential. The E. coli strains used in the trials were rated LT positive. The papaya leaf extracts (Carica papaya Linn showed no microbicidal activity while the guava sprout extracts (Psidium guajava Linn displayed halos exceeding 13 mm for both species, an effect considered to be inhibitory by the method employed. Guava sprout extracts by 50% diluted ethanol most effectively inhibited E. coli (EPEC, while those in 50% acetone were less effective. It may be concluded that guava sprout extracts constitute a feasible treatment option for diarrhea caused by E. coli or by S. aureus-produced toxins, due to their quick curative action, easy availability in tropical countries and low cost to the consumer.Foram coletadas doze amostras de camarão e peixes nas imediações do interceptor oceânico, em Fortaleza e igual número na Feira de pescado do Mucuripe, Fortaleza, para isolamento de E. coli e Staphylococcus aureus, respectivamente.

    GLABRA3 (GL3), a bHLH transcription factor, has previously proved to be involved in anthocyanin biosynthesis and trichome formation in Arabidopsis, however, its downstream targeted genes are still largely unknown. Here, we found that GL3 was widely present in Arabidopsis vegetative and reproductive organs. New downstream targeted genes of GL3 for anthocyanin biosynthesis and trichome formation were identified in young shoots and expanding true leaves by RNA sequencing. GL3-mediated gene expression was tissue specific in the two biological processes. This study provides new clues to further understand the GL3-mediated regulatory network of anthocyanin biosynthesis and trichome formation in Arabidopsis. Copyright © 2017 Elsevier Inc.

    Sida cordifolia Linn. (Malvaceae) is a plant used in folk medicine for the treatment of the inflammation of oral mucosa, asthmatic bronchitis, nasal congestion and rheumatism. We studied the hepatoprotective activity of 50 % ethanolic extract of S. cordifolia Linn. against alcohol intoxication. The duration of the experiment was 90 d. The substantially elevated levels of toxicity markers such as alanine aminotransferase, aspartate aminotransferase and γ-glutamyl transferase due to the alcohol treatment were significantly lowered in the extract-treated groups. The activity of antioxidant enzymes and glutathione content, which was lowered due to alcohol toxicity, was increased to a near-normal level in the co-administered group. Lipid peroxidation products, protein carbonyls, total collagen and hydroxyproline, which were increased in the alcohol-treated group, were reduced in the co-administered group. The mRNA levels of cytochrome P450 2E1, NF-κB, TNF-α and transforming growth factor-β1 were found to be increased in the alcohol-treated rats, and their expressions were found to be decreased in the co-administered group. These observations were reinforced by histopathological analysis. Thus, the present study clearly indicates that 50 % ethanolic extract of the roots of S. cordifolia Linn. has a potent hepatoprotective action against alcohol-induced toxicity, which was mediated by lowering oxidative stress and by down-regulating the transcription factors.

    Plants are the real basis towards animal life and are also central to people's livelihood. The contributions of the plants in performing varied religious celebrations and in other multiple beneficiaries like medicine, human happiness as well as in treating deadly diseases can never be neglected. In treating diseases, the plants and their constituents are better choice than any other synthetic chemical. The nature has been kind enough to provide the human beings with various types of medicinal plants and in the real sense these form the storehouse of curing almost all the ailments. Consequently, most of the drugs which are being used in preparing formulations have their origin and roots in the plants which form the chief natural source of medicines. Even in modern era, the plant-derived drugs are being extensively used, either in their original or semi-synthetic form. It is because their natural phytoconstituents are highly innocuous posing relatively fewer or no side effects. Based upon their observations, analysis and experience, our ancestors used many plants for medicinal purposes and thus their efforts need to be supported by scientific evidence. Jasminum grandiflorum Linn. is one of such important plants. It has been extensively used by the tribes all over India to treat different diseases which mainly include body pains, toothache, stomach ache, ulcers, and sexual impotency. Chemistry of the plant revealed the presence of mainly secoiridoids, terpenoids, flavonoids and tannins. Not much scientific support was given to the folklore claims for this plant but some of its traditional uses were investigated like spasmolytic, wound healing, antimicrobial, angiotensin converting enzyme inhibitor, antiulcer and antioxidant activities. This article is the review of research works done on the plant Jasminum grandiflorum Linn. to date. As a part of it the local names, morphology, traditional claims, chemistry and pharmacological activities have been discussed.

    Liquorice is the root of Glycyrrhiza uralensis Fisch. or Glycyrrhiza glabra L., Leguminosae. Licorice is described as 'National Venerable Master' in Chinese medicine and plays paradoxical roles, i.e. detoxification/strengthen efficacy and inducing/enhancing toxicity. Therefore, licorice was called "Two-Face" herb in this paper. The aim of this study is to discuss the paradoxical roles and the perspective usage of this "Two-Face" herb using data mining and frequency analysis. More than 96,000 prescriptions from Chinese Formulae Database were selected. The frequency and the prescription patterns were analyzed using Microsoft SQL Server 2000. Data mining methods (frequent itemsets) were used to analyze the regular patterns and compatibility laws of the constituent herbs in the selected prescriptions. The result showed that licorice (Radix glycyrrhizae) was the most frequently used herb in Chinese Formulae Database, other frequently used herbs including Radix Angelicae Sinensis (Dang gui), Radix et rhizoma ginseng (Ren shen), etc. Toxic herbs such as Radix aconiti lateralis praeparata (Fu zi), Rhizoma pinelliae (Ban xia) and Cinnabaris (Zhu sha) are top 3 herbs that most frequently used in combination with licorice. Radix et rhizoma ginseng (Ren shen), Poria (Fu ling), Radix Angelicae Sinensis (Dang gui) are top 3 nontoxic herbs that most frequently used in combination with licorice. Moreover, Licorice was seldom used with sargassum (Hai Zao), Herba Cirsii Japonici (Da Ji), Euphorbia kansui (Gan Sui) and Flos genkwa (Yuan Hua), which proved the description of contradictory effect of Radix glycyrrhizae and these herbs as recorded in Chinese medicine theory. This study showed the principle pattern of Chinese herbal drugs used in combination with licorice or not. The principle patterns and special compatibility laws reported here could be useful and instructive for scientific usage of licorice in clinic application. Further pharmacological and chemical researches are

    In order to explore the effect of Mirabilis jalapa Linn. growth on the structure characteristics of the microbial community and the degradation of petroleum hydrocarbon (TPH) in the petroleum-contaminated saline-alkali soil, Microbial biomass and species in the rhizosphere soils of Mirabilis jalapa Linn. in the contaminated saline soil were studied with the technology of phospholipid fatty acids (PLFAs) analysis. The results showed that comparing to CK soils without Mirabilis jalapa Linn., the ratio of PLFAs species varied were 71. 4%, 69. 2% and 33. 3% in the spring, summer and autumn season, respectively. In addition, there was distinct difference of the biomasses of the microbial community between the CK and rhizosphere soils and among the difference seasons of growth of Mirabilis jalapa Linn.. Compare to CK soil, the degradation rates of total petroleum hydrocarbon (TPH) was increased by 47. 6%, 28. 3%, and 18. 9% in spring, summer, and autumn rhizosphere soils, respectively. Correlation analysis was used to determine the correlation between TPH degradation and the soil microbial community. 77. 8% of the total soil microbial PLFAs species showed positive correlation to the TPH degradation (the correlation coefficient r > 0), among which, 55. 6% of PLFAs species showed high positive correlation(the correlation coefficient was r≥0. 8). In addition, the relative content of SAT and MONO had high correlation with TPH degradation in the CK sample soils, the corelation coefficient were 0. 92 and 0. 60 respectively; However, the percent of positive correlation was 42. 1% in the rhizosphere soils with 21. 1% of them had high positive correlation. The relative content of TBSAT, MONO and CYCLO had moderate or low correlation in rhizosphere soils, and the correlation coefficient were 0. 56, 0. 50, and 0. 07 respectively. Our study showed that the growth of mirabilis Mirabilis jalapa Linn. had a higher influence on the species and biomass of microbial community in the

    Sarcandra glabra (Thunb.) Nakai, colloquially known as Caoshanhu, is a Chinese medicinal herb with reported anti-tumor, anti-inflammatory, anti-viral and non-specific immunoenhancing properties. Although the plant has been clinically used for treating a variety of diseases, its bioactive ingredients are largely unknown and its mode of action has never been investigated. In this study, the anti-tumor property of ethyl acetate (EA) extract of S. glabra was investigated by determining its in vitro growth-inhibitory effects on a panel of human cancer cell lines of different histotypes. Growth inhibition of the EA extract on the cancer cells seemed to be selective, and the leukemic HL-60 was found to be the most responsive after 48 h of treatment (IC50=58 microg/ml). Flow cytometric studies further illustrated that the extract might interfere with DNA replication and thus arrested the cell cycle at S phase in the leukemic cells, followed by DNA fragmentation and loss of phospholipid asymmetry in the plasma membrane after 72 h of treatment. Concurrently, the pro-apoptotic Bax/Bcl-2 ratio was also up-regulated by more than 178% of the control level. All these findings suggested that the extract had initiated apoptosis to kill the leukemic cells. Results from this pioneer study help to establish a scientific foundation for future research and development of the bioactive ingredients in EA extract of S. glabra as efficacious anti-cancer agents.

    Full Text Available Licorice is the root of Glycyrrhiza glabra, which has a herbal ingredient, glycyrrhizic acid. Excessive intake of licorice may cause a hypermineralocorticoidism-like syndrome characterized by sodium and water retention, hypokalemia, hypertension, metabolic alkalosis, low-renin activity, and hypoaldosteronism. In this paper, an 34 years old man who admitted to the emergency department with respiratory failure and marked muscle weakness of all extremities that progressed to paralysis after excessive intake of licorice syrup was presented. It was aimed to draw attention to the necessity of questioning whether there is excessive intake of licorice or not in patients who admitted to emergency department with paralysis and dyspnea. Plasma potassium concentration of the patient was 1.4 mmol/L. The patient\\'s respiratory distress and loss of muscle strength recovered completely after potassium replacement.

    Full Text Available Malaria is one of the most prevailing fatal diseases causing between 1.2 and 2.7 million deaths all over the world each year. Further, development of resistance against the frontline anti-malarial drugs has created an alarming situation, which requires intensive drug discovery to develop new, more effective, affordable and accessible anti-malarial agents possessing novel modes of action. Over the past few years triterpenoids from higher plants have shown a wide range of anti-malarial activities. As a part of our drug discovery program for anti-malarial agents from Indian medicinal plants, roots of Glycyrrhizaglabra were chemically investigated, which resulted in the isolation and characterization of 18β-glycyrrhetinic acid (GA as a major constituent. The in vitro studies against P. falciparum showed significant (IC50 1.69 µg/ml anti-malarial potential for GA. Similarly, the molecular docking studies showed adequate docking (LibDock score of 71.18 for GA and 131.15 for standard anti-malarial drug chloroquine. Further, in silico pharmacokinetic and drug-likeness studies showed that GA possesses drug-like properties. Finally, in vivo evaluation showed a dose dependent anti-malarial activity ranging from 68-100% at doses of 62.5-250 mg/kg on day 8. To the best of our knowledge this is the first ever report on the anti-malarial potential of GA. Further work on optimization of the anti-malarial lead is under progress.

    This study was conducted to investigate the possible role of Licorice against damages induced by gamma rays. Adult female albino rats (130-140 g) were divided into four groups. Group 1: control animals, group 2: rats whole body exposed to gamma radiations (6.5 Gy), group 3: animals received Licorice in drinking water for four weeks (100 mg/ kg body wt/ day), and group 4: received Licorice two weeks before and two weeks after irradiation. Blood and liver samples were obtained two weeks post-irradiation. Total cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C), glucose, sodium (Na + ) and potassium (K + ) levels were determined in serum. Per oxidative hepatic damage was studied by assessing; thiobarbituric acid reactive substances (TBARs) and reduced glutathione (GSH) contents, as well as, superoxide dismutase (SOD) and catalase (CAT) activities in liver tissue. The data obtained revealed a significant increase in serum glucose, K + , TC, TG and LDL-C and liver TABRs. While, significant decreases were recorded for serum Na + and HDL-C levels, liver GSH content, SOD and CAT activities. On the other hand, Licorice treated irradiation rats showed a significant amelioration in the changes produced by gamma radiation with variable degree. Thus, it could be concluded that Licorice might provide protection against radiation-induced disturbances in metabolic activities and oxidative damage in liver tissues

    Laūq is a pharmaceutical dosage form that had been mainly used for the treatment of various respiratory disorders in traditional Persian medicine. It is important from 2 aspects: a dosage form with efficient and optimum delivery of drugs to the respiratory tract and biological effects of its ingredients. Natural medicine in laūq has been demonstrated to act in respiratory disorders by their antitussive, antiallergic, anti-inflammatory, antioxidant, spasmolytic, and antibacterial activities. Some of these natural remedies act by most of the mentioned mechanisms such as Cydonia oblonga, Glycyrrhiza glabra, Crocus sativus, Hyssopus officinalis, Foeniculum vulgare, and honey. However, the evidence is limited including Cassia fistula, Papaver somniferum, and Drimia maritima. According to positive pharmacokinetic and pharmacodynamic aspects of laūqs, they may be considered as efficient dosage forms for delivery of drugs to the respiratory tract. For better compatibility of patients, it could be substituted laūqs with newer drug delivery systems like lozenges. © The Author(s) 2015.

    In Arabidopsis thaliana, the R3-type MYB transcription factor CAPRICE (CPC) and bHLH transcription factor GLABRA3 (GL3) cooperatively regulate epidermal cell differentiation. CPC and GL3 are involved in root-hair differentiation, trichome initiation and anthocyanin biosynthesis in Arabidopsis epidermal cells. Previously, we showed that CPC and GL3 also influence anthocyanin accumulation in tomato. Introduction of 35S::CPC into tomato significantly inhibits anthocyanin accumulation in cotyledons, leaves and stems. In contrast, introduction of GL3::GL3 strongly enhances anthocyanin accumulation in cotyledons, leaves and stems of tomato. In this study, we investigated the effect of CPC and GL3 on anthocyanin accumulation in the epidermis of tomato fruit. Unlike the results with vegetative tissues, overexpression of CPC and GL3 did not influence anthocyanin biosynthesis in tomato fruit peel.

    2006-11-01

    Full Text Available Screening experiments using 25-1 fractional factorial design showed that pH, temperature, and extracting time were the main factors affecting the amount and quality of extracted pectin from Citrus medica Linn. Optimum condition of pectin extraction was studied using central composite design (CCD. Mathematical models relating pH, temperature and extracted time to amount of extracted pectin, equivalent weight, methyl content and anhydrogalacturonic acid content were established. Based on the mathematics models, the condition of pH 2, 100ºC and 105 min was found to be the optimum conditions for pectin extraction from Citrus medica Linn. Mathematical and experimental results were verified. The use of extracted pectin as a gelling agent in pineapple jam revealed no significant difference in gel consistency compared to that of commercial pectin grade 150 (p>0.05. However, the commercial pectin had a higher liking score on the spreadability, texture and overall liking. As a stabilizer in chocolate pasteurised milk, 0.2% of the extracted pectin was required to prevent precipitation of chocolate powder with the similar viscosity obtained from 0.06% κ-carageenan

    Full Text Available Beringin (Ficus benjamina Linn. is one of typical fast growing tree species which are commonly found in Indonesia. The trees grow with hanging roots which grow larger and often can merged with the main stem, then its timber is not optimally utilized. This paper studies the anatomical structure and fiber quality of main stem and large, medium, and small diameter of hanging roots of beringin (Ficus benjamina Linn. tree. Anatomical structure was observed macroscopically and microscopically, while fiber dimensions were measured from macerated samples. The results show that the anatomical structure pattern of the roots is similar with those of main stem, however the quantity and dimension of anatomical components of hanging roots are smaller and shorter than components of main stem. Likewise, the fiber dimensions of roots are shorter and thinner than those taken from the main stem. Based on fiber dimensions and its derivative value, beringin wood fibers are classified into class quality II for pulp and paper. The creamy white color with white streaky figure of beringin wood from main stem is recommended for indoor decoration products such as wooden venetian blind, while the small roots are recommended for strap or webbing material crafts.

    In order to obtain the fungicides with minimal impact on efficiency of mycorrhizal symbiosis, the effect of five fungicides including polyoxins, jinggangmycins, thiophanate methylate, chlorothalonil and carbendazim on the growth of medicinal plant and efficiency of mycorrhizal symbiosis were studied. Pot cultured Glycyrrhiza uralensis was treated with different fungicides with the concentration that commonly used in the field. 60 d after treated with fungicides, infection rate, infection density, biomass indexes, photosyn- thetic index and the content of active component were measured. Experimental results showed that carbendazim had the strongest inhibition on mycorrhizal symbiosis effect. Carbendazim significantly inhibited the mycorrhizal infection rate, significantly suppressed the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. Polyoxins showed the lowest inhibiting affection. Polyoxins had no significant effect on mycorrhizal infection rate, the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. The other three fungicides also had an inhibitory effect on efficiency of mycorrhizal symbiosis, and the inhibition degrees were all between polyoxins's and carbendazim's. The author considered that fungicide's inhibition degree on mycorrhizal effect might be related with the species of fungicides, so the author suggested that the farmer should try to choose bio-fungicides like polyoxins.

    Linné is a simple crater, with a diameter of 2.23 km and a depth of 0.52 km, located in northwestern Mare Serenitatis. Recent high-resolution data acquired by the Lunar Reconnaissance Orbiter Camera revealed that the shape of this impact structure is best described by an inverted truncated-cone. We perform morphometric measurements, including slope and profile curvature, on the Digital Terrain Model of Linné, finding the possible presence of three subtle topographic steps, at the elevation of +20, -100, and -200 m relative to the target surface. The kink at -100 m might be related to the interface between two different rheological layers. Using the iSALE shock physics code, we numerically model the formation of Linné crater to derive hints on the possible impact conditions and target physical properties. In the initial setup, we adopt a basaltic projectile impacting the Moon with a speed of 18 km s-1. For the local surface, we consider either one or two layers, in order to test the influence of material properties or composite rheologies on the final crater morphology. The one-layer model shows that the largest variations in the crater shape take place when either the cohesion or the friction coefficient is varied. In particular, a cohesion of 10 kPa marks the threshold between conical- and parabolic-shaped craters. The two-layer model shows that the interface between the two layers would be exposed at the observed depth of 100 m when an intermediate value ( 200 m) for the upper fractured layer is set. We have also found that the truncated-cone morphology of Linné might originate from an incomplete collapse of the crater wall, as the breccia lens remains clustered along the crater walls, while the high-albedo deposit on the crater floor can be interpreted as a very shallow lens of fallout breccia. The modeling analysis allows us to derive important clues on the impactor size (under the assumption of a vertical impact and collision velocity equal to the mean

    The pastoral lifestyle of Indigenous communities of Bajaur Agency is bringing them close to natural remedies for treating their domestic animals. Several studies have been conducted across the globe describing the importance of traditional knowledge in veterinary care. Therefore, this study was planned with the aim to record knowledge on ethnoveterinary practices from the remote areas and share sit with other communities through published literature. Data was gathered from community members through semi-structured interviews and analyzed through informant consensus factor (Fic) to evaluate the consent of current ethnoveterinary practices among the local people. In total, 73 medicinal plants were recorded under the ethnoveterinary practices. Most widely used medicinal plants with maximum use reports (URs) were Visnaga daucoides Gaertn., Foeniculum vulgare Mill., Solanum virginianum L., Withania somnifera (L.) Dunal, Glycyrrhiza glabra L., and Curcuma longa L. New medicinal values were found with confidential level of citations for species including Heracleum candicans and Glycerhiza glabra. Family Apiaceae was the utmost family with high number (7 species) of medicinal plants. Maximum number of medicinal plants (32) was used for gastric problems. High Fic was recorded for dermatological (0.97) followed by reproductive (0.93) and gastrointestinal disorders (0.92). The main route of remedies administration was oral. Current study revealed that the study area has sufficient knowledge on ethnoveterinary medicinal plants. This knowledge is in the custody of nomadic grazers, herders, and aged community members. Plants with new medicinal uses need to be validated phytochemically and pharmacologically for the development of new alternative drugs for veterinary purposes.

    Gastric ulcer is a common chronic disease in human digestive system, which is difficult to cure, easy to relapse, and endangers human health seriously. Compared with western medicine, traditional Chinese medicine has a unique advantage in improving the general situation, stablizing medical condition, and with little side effects. Glycyrrhiza known as "king of all the medicine", has a range of pharmacological activities and is commonly used in a variety of proprietary Chinese medicines and formulations. On the basis of explicit antiulcer effect of Glycyrrhiza triterpenes, the molecular mechanisms of its therapeutic effect on acetic acid induced gastric ulcer in rats were explored. Acetic acid induced gastric ulcer model in rats was established to evaluate the curing effect of G. triterpenes and all of the rats were randomised into six groups: Control group, model group, omeprazole group (0.8 mg/mL), triterpenes high dose group (378.0 mg/mL), triterpenes middle dose group (126.0 mg/mL), and triterpenes low dose group (42.0 mg/mL). All rats in groups were orally administered the active group solution 1.5 mL once daily (model and control groups with saline) for 7 days. HPLC-TOF-MS analysis method was performed to obtain the plasma metabolites spectrums of control group, model group, triterpenes high, middle and low dose groups. A total of 11 differential endogenous metabolites related to the therapeutic effect of G. triterpenes were identified, including tryptophan, phingosine-1-phosphate, pantothenic acid, and so on, among which tryptophan and phingosine-1-phosphate are related with the calcium signaling pathway and arachidonic acid (AA) metabolism. At the same time, in order to verify the above results, quantitative real time polymerase chain reaction were performed to evaluate the expression of H + -K + -ATPase alpha mRNA and phospholipase a 2 mRNA in relational signaling pathways.

    Full Text Available Licorice is one of the most generally used herbal medicines in the world; however, wild licorice resources have decreased drastically. Cultivated Glycyrrhiza uralensis Fischer are the main source of licorice at present, but the content of main active components in cultivated G. uralensis are lower than in wild G. uralensis. Therefore, the production of high-quality cultivated G. uralensis is an urgent issue for the research and production fields. In this study, the content of five active components and seven endogenous phytohormones in cultivated G. uralensis (two-year-old were determined by high-performance liquid chromatography (HPLC and enzyme-linked immunosorbent assay (ELISA, respectively. Furthermore, different concentrations (25–200 mg/L of exogenous abscisic acid (ABA were sprayed on the leaves of G. uralensis in the fast growing period. Results showed that ABA, zeatin riboside (ZR, and dihydrozeatin riboside (DHZR had strong correlation with active components. In addition, the content of five active components increased remarkably after ABA treatment. Our results indicate that ABA is significantly related to the accumulation of active components in G. uralensis, and the application of exogenous ABA at the proper concentration is able to promote the accumulation of main components in G. uralensis.

    BACKGROUND This study performed optimized extraction, preliminary characterization, and in vitro antioxidant activities of polysaccharides from Glycyrrhiza uralensis Fisch. MATERIAL AND METHODS Three parameters (extraction temperature, ratio of water to raw material, and extraction time) were optimized for yields of G. uralensis polysaccharides (GUP) using response surface methodology with Box-Behnken design (BBD). The GUP was purified using DEAE cellulose 32-column chromatography. The main fraction obtained from G. uralensis Fisch was GUP-II, which was composed of rhamnose, arabinose, galactose, and glucose monosaccharide, was screened for antioxidant properties using DP Hand hydroxyl radical scavenging assays. In addition, immunological activity of GUP-II was determined by nitric oxide and lymphocyte proliferation assays. RESULTS Optimization revealed maximum GUP yields with an extraction temperature of 99°C, water: raw material ratio of 15: 1, and extraction duration of 2 h. GUP-II purified from G. uralensis Fisch had good in vitro DPPH and hydroxyl radical scavenging abilities. Immunologically, GUP-II significantly stimulated NO production in RAW 264.7 macrophages, and significantly enhanced LPS-induced lymphocyte proliferation. CONCLUSIONS Extraction of GUP from G. uralensis Fisch can be optimized with respect to temperature, extraction period, and ratio of water to material, using response surface methodology. The purified product (GUP-II) possesses excellent antioxidant and immunological activities.

    Full Text Available Effect of Gibberellins (GA4 on Germination Time and Height of Cendana (Santalum album Linn.  The hemiparasite Santalum album Linn. (cendana grows very slow, in nature the rare and difficult seeds need stimulation to germinate. Gibberellins (including GA4 are growth regulators, usually used to increase growth as well as to break seed dormancy. The objectives of this research were to investigate the influence of gibberellins on germination percentage and height of cendana growth. Experiment was laid out in a Completely Randomized Design with 3 replicates of 300 seeds for germination percentage and 3 replicates of 10 seeds for seedling growth. Gibberellin was applied as treatment with 100, 300, and 500 ppm. The seed germination was recorded until 9 weeks, and height of plants measured until 8 months at the greenhouse. The results showed that the addition of gibberellins at all treatment increased the percentage of germination and caused the seeds germinated four weeks earlier than the control. In the first 4 months, 500 ppm gibberellins gave the highest acceleration of germination, afterward all treatments have relatively the same influences. Gibberellins gave positive effect on height of cendana growth. After 7 months, the growth decreased although all gibberellin treatments gave higher growth than the control.

    New developments in the realm of skin rejuvenation such as phytotherapy are at an astounding increasing pace in the cosmeceutical market. Yet, many of these products that are classified as cosmeceuticals are tested less vigorously and do not have to be approved by the Food and Drug Administration to establish efficacy and safety. Thus, as clinicians, we must ask the question, "Is there science-based evidence to validate the mechanism of these new treatments?" We assessed the top anti-aging creams currently on the market specifically evaluating their botanical ingredients. Some of the most common botanicals that are hot off the market are: Rosmarinus officinalis, Vitis vinifera (grape seed extract), Citronellol, Limonene, Oenothera biennis (evening primrose), Glycyrrhiza glabra (licorice extract), Aframomum angustifolium seed extract, Diosgenin (wild yam), N6 furfuryladenine (kinetin), and Ergothioneine. Through researching each of these botanical ingredients, we have concluded that randomized controlled trials are still needed in this area, but there is promise in some of these ingredients and science to validate them. © 2010 Wiley Periodicals, Inc.

    Full Text Available Idiopathic pulmonary fibrosis is a progressive and lethal form of interstitial lung disease that lacks effective therapies at present. Glycyrrhizic acid (GA, a natural compound extracted from a traditional Chinese herbal medicine Glycyrrhiza glabra, was recently reported to benefit lung injury and liver fibrosis in animal models, yet whether GA has a therapeutic effect on pulmonary fibrosis is unknown. In this study, we investigated the potential therapeutic effect of GA on pulmonary fibrosis in a rat model with bleomycin (BLM-induced pulmonary fibrosis. The results indicated that GA treatment remarkably ameliorated BLM-induced pulmonary fibrosis and attenuated BLM-induced inflammation, oxidative stress, epithelial-mesenchymal transition and activation of tansforming growth factor-beta signaling pathway in the lungs. Further, we demonstrated that GA treatment inhibited proliferation of 3T6 fibroblast cells, induced cell cycle arrest and promoted apoptosis in vitro, implying that GA-mediated suppression of fibroproliferation may contribute to the anti-fibrotic effect against BLM-induced pulmonary fibrosis. In summary, our study suggests a therapeutic potential of GA in the treatment of pulmonary fibrosis.

    The aims of this study were to examine the bioactive component(s) responsible for the anticoagulant activity of M. malabathricum Linn. leaf hot water crude extract via bioassay-guided fractionation and to evaluate the effect of bioactive component(s) on the intrinsic blood coagulation pathway. The active anticoagulant fraction of F3 was subjected to a series of chromatographic separation and spectroscopic analyses. Furthermore, the effect of the bioactive component(s) on the intrinsic blood coagulation pathway was studied through immediate and time incubation mixing studies. Through Activated Partial Thromboplastin Time (APTT) assay-guided fractionation, Subfraction B was considered the most potent anticoagulant fraction. Characterisation of Subfraction B indicated that anticoagulant activity could partly be due to the presence of cinnamic acid and a cinnamic acid derivative. APTT assays for both the immediate and time incubation mixing were corrected back into normal clotting time range (35.4-56.3 s). In conclusion, cinnamic acid and cinnamic acid derivative from Subfraction B were the first such compounds to be discovered from M. malabathricum Linn. leaf hot water crude extract that possess anticoagulant activity. This active anticoagulant Subfraction B prolonged blood clotting time by causing factor(s) deficiency in the intrinsic blood coagulation pathway.

    The aim of the present study was to investigate the correlation between root respiration and the levels of biomass and glycyrrhizic acid in Glycyrrhiza uralensis . Root respiration was determined using a biological oxygen analyzer. Respiration-related enzymes including glucose-6-phosphate dehydrogenase plus 6-phosphogluconate dehydrogenase, phosphohexose isomerase and succinate dehydrogenase, and respiratory pathways were evaluated. Biomass was determined by a drying-weighing method. In addition, the percentage of glycyrrhizic acid was detected using high-performance liquid chromatography. The association between root respiration and the levels of biomass and glycyrrhizic acid was investigated. The glycolysis pathway (EMP), tricarboxylic acid cycle (TCA) and pentose phosphate (PPP) pathway acted concurrently in the roots of G. uralensis . Grey correlation analysis showed that TCA had the strongest correlation (correlation coefficient, 0.8003) with biomass. Starch and acetyl coenzyme A had the closest association with above-ground biomass, while soluble sugar correlated less strongly with above-ground biomass. Grey correlation analysis between biochemical pathways and the intermediates showed that pyruvic acid had the strongest correlation with EMP, while acetyl coenzyme A correlated most strongly with TCA. Among the intermediates and pathways, pyruvic acid and EMP exhibited the greatest correlation with glycyrrhizic acid, while acetyl coenzyme A and TCA correlated with glycyrrhizic acid less closely. The results of this study may aid the cultivation of G. uralensis . However, these results require verification in further studies.

    Objectives: The antiplaque and antigingivitis effects of a gel containing 10% Punica granatum Linn extract were evaluated using a 21-day partial-mouth experimental model of gingivitis. Methods: 23 volunteers participated in this cross-over, doubleblind study, carried out in 2 phases of 21 days each. For each period of the experiment, an acrylic toothshield was made for each volunteer to carry the test or placebo gel as well as to avoid brushing of the 4 experimental teeth (posterior teeth in the lower left quadrant). The subjects were randomly assigned to use either the placebo gel (control group) or the test gel (experimental group) and were instructed to brush the remaining teeth normally 3 times a day. On days 0 and 21, the visible plaque index (VPI) and gingival bleeding index (GBI) were recorded. Results: The results did not show statistically significant difference between control and experimental groups for either of the indices (VPI and GBI). Conclusion: The gel containing 10% Punica granatum Linn extract was not efficient in preventing supragingival dental plaque formation and gingivitis. PMID:19089066

    The aim of this study is to investigate the rat intestinal absorption behavior of two main active components, liquiritin, glycyrrhizin and the extract of Glycyrrhiza uralensis. The rat intestinal perfusion model was employed. Concentrations of the compounds of the interest in the intestinal perfusate, bile and plasma samples were determined by HPLC and UPLC. At the same time, the intestinal enzymes incubation test and the partition coefficient determination, the absorption of liquiritin and glycyrrhizin alone and the extract were multiple analyzed. The results showed that the P(eff) (effective permeability) of liquiritin or glycyrrhizin alone or the extract was less than 0.3, which suggested their poor absorption in the intestine. The P(eff) of the two main active components or the extract was not significantly different in duodenum, jejunum, colon and ileum segment. The P(eff) of the glycyrrhizin in the extract had no significant difference in the four intestinal segments compared with the glycyrrhizin alone. The absorption of the liquiritin displayed significant difference (P components might not increase the amount of liquiritin and glycyrrhizin in the bile and plasma within the duration of the test.

    The radioprotective role of aqueous extract of Mentha piperita (Linn.) (RUBL 19443) against radiation induced hematological alterations in peripheral blood of Swiss albino mice was studied at various post-irradiation intervals between 6 hrs to 30 days. Oral administration of Mentha extract (ME) (1 gm/kg body weight) prior to whole-body irradiation showed a significant protection in terms of survival percentage and hematological parameters. Mice exposed to radiation (10 Gy) without ME pre-treatment exhibited signs of radiation sickness like anorexia, lethargicity, ruffled hairs and diarrhoea and such animals died within 10 days post-irradiation. Conversely, animals pre-treated with ME showed 58 percent survival until 30 days after exposure. A significant decline in hematological constituents was evident until day 5, at later period of observation (day 5 onwards), no animals could survive from control group whereas, in ME pre-treated irradiated group, a gradual recovery was noted in the hematological values. However, these hematological values remained significantly below the normal even till day 30. The results from the present study suggest that Mentha piperita (Linn.) has radioprotective role in stimulating/protecting the hematopoietic system thereby enhancing the survival and increasing the hematological constituents in peripheral blood of mice against lethal dose of gamma radiation.

    Gmelina asiatica Linn (G. parvifolia Roxb.) is a large shrub or a small tree. Roots and aerial parts are used in Ayurvedic medicine and also have ethno-medical uses. Root is reported as adulterant to G. arborea roxb roots. Pharmacognostical characters of root were reported. Owing to the shortage of genuine drug and ever-increasing demands in market, it becomes necessary to search an alternative with equal efficacy without compromising the therapeutic value. Nowadays, it becomes a common practice of using stem. In case of roots phytochemical and pharmacological analysis of stem was reported. However, there is no report on the pharmacognostical characters of stem and to differentiate it from roots. The present report describes the botanical pharmacognostical characters of stem and a note to differentiate it from root. Hollow pith, faint annual rings in cut ends, alternatively arranged macrosclereids and bundle cap fibers, and presence of abundant starch grains and calcium oxalates in pith and in ray cells are the diagnostic microscopic characters of stem. Stem pieces can be differentiated from roots by absence of tylosis.

    Reactive oxygen species (ROS), among other factors, have been implicated in the aetiology of male infertility. Thus, the roles of antioxidants at improving sperm production and quality are being investigated. The present study was designed to assess the effect of the ethanol extract of fresh leaves of Psidium guajava Linn. on the sperm parameters of healthy male Wistar rats. A total of 18 rats, weighing between 108-124 g, were divided into 3 groups of 6 animals each. Animals in groups 1 and 2 were administered 250 mg/kg/d and 500 mg/kg/d of guava leaf extract (GLE) orally for 53 days respectively. Group 3 animals received normal saline. Sperm count increased from 56.2+/-0.3 (x10(6)) in the control to 57.1+/-0.2 (x10(6)) in group 1 animals, and from 56.2+/-0.3 (x10(6)) in the control to 72.3+/-0.4 (x10(6)) in group 2 animals. Similarly, dose-dependent increases in the percentages of motile spermatozoa were observed in GLE-treated animals compared to the control group. These findings suggest that the extracts of the leaves of Psidium guajava Linn. possess beneficial effects on sperm production and quality, and may thus improve the sperm parameters of infertile males with oligospermia and nonobstructive azoospermia.

    Full Text Available Aims: Pseudomonas aeruginosa is a drug resistance opportunistic bacterium. Biofilm formation is key factor for survivalof P. aeruginosa in various environments. Polysaccharides may be involved in biofilm formation. The purpose of thisstudy was to evaluate antimicrobial and anti-biofilm activities of seven plant extracts with known alpha-glucosidaseinhibitory activities on different strains of P. aeruginosa.Methodology and results: Plants were extracted with methanol by the maceration method. Antimicrobial activities weredetermined by agar dilution and by growth yield as measured by OD560nm of the Luria Bertani broth (LB culture with orwithout extracts. In agar dilution method, extracts of Quercus infectoria inhibited the growth of all, while Myrtuscommunis extract inhibited the growth of 3 out of 8 bacterial strains with minimum inhibitory concentration (MIC of 1000μg/mL. All extracts significantly (p≤0.003 reduced growth rate of the bacteria in comparison with the control withoutextracts in LB broth at sub-MIC concentrations (500 μg/mL. All plant extracts significantly (p≤0.003 reduced biofilmformation compared to the controls. Glycyrrhiza glabra and Q. infectoria had the highest anti-biofilm activities. Nocorrelation between the alpha-glucosidase inhibitory activity with growth or the intensity of biofilm formation was found.Conclusion, significance and impact of study: Extracts of Q. infectoria and M. communis had the most antimicrobial,while Q. infectoria and G. glabra had the highest anti-biofilm activities. All plant extracts had anti-biofilm activities withmarginal effect on growth, suggesting that the mechanisms of these activities are unrelated to static or cidal effects.Further work to understand the relation between antimicrobial and biofilm formation is needed for development of newmeans to fight the infectious caused by this bacterium in future.

    Full Text Available Diacetyl (2,3-butanedione is a key contributor to unpleasant odors emanating from the axillae, feet, and head regions. To investigate the mechanism of diacetyl generation on human skin, resident skin bacteria were tested for the ability to produce diacetyl via metabolism of the main organic acids contained in human sweat. L-lactate metabolism by Staphylococcus aureus and Staphylococcus epidermidis produced the highest amounts of diacetyl, as measured by high-performance liquid chromatography. Glycyrrhiza glabra root extract (GGR and α-tocopheryl-L-ascorbate-2-O-phosphate diester potassium salt (EPC-K1, a phosphate diester of α-tocopherol and ascorbic acid, effectively inhibited diacetyl formation without bactericidal effects. Moreover, a metabolic flux analysis revealed that GGR and EPC-K1 suppressed diacetyl formation by inhibiting extracellular bacterial conversion of L-lactate to pyruvate or by altering intracellular metabolic flow into the citrate cycle, respectively, highlighting fundamentally distinct mechanisms by GGR and EPC-K1 to suppress diacetyl formation. These results provide new insight into diacetyl metabolism by human skin bacteria and identify a regulatory mechanism of diacetyl formation that can facilitate the development of effective deodorant agents.

    Full Text Available In many developing countries, jaundice is the common symptom of hepatic diseases which are a major cause of mortality. The use of natural product-based therapies is very popular for such hepatic disorders. A great number of medicinal plants have been utilized for this purpose and some facilitated the discovery of active compounds which helped the development of new synthetic drugs against jaundice. However, more epidemiological studies and clinical trials are required for the practical implementation of the plant pharmacotherapy of jaundice. The focus of this second part of our review is on several of the most prominent plants used against jaundice identified in the analysis performed in the first part of the review viz. Andrographis paniculata (Burm.f. Nees, Silybum marianum (L. Gaertn., Terminalia chebula Retz., Glycyrrhiza glabra L. and some species of genus Phyllanthus. Furthermore, we discuss their physiological effects, biologically active ingredients, and the potential mechanisms of action. Some of the most important active ingredients were silybin (also recommended by German commission, phyllanthin and andrographolide, whose action leads to bilirubin reduction and normalization of the levels of relevant serum enzymes indicative for the pathophysiological status of the liver.

    Polycystic ovary syndrome (PCOS) is a common, complex reproductive endocrinopathy characterized by menstrual irregularities, hyperandrogenism and polycystic ovaries. Lifestyle modification is a first‐line intervention; however, there are barriers to success for this form of self‐care, and women often seek adjunct therapies including herbal medicines. This pragmatic, randomized controlled trial, delivered in communities of Australia in overweight women with PCOS, compared the effectiveness and safety of a lifestyle intervention plus herbal medicine against lifestyle alone. All participants were helped to construct a personalized lifestyle plan. The herbal intervention consisted of two tablets. Tablet 1 contained Cinnamomum verum, Glycyrrhiza glabra, Hypericum perforatum and Paeonia lactiflora. Tablet 2 contained Tribulus terrestris. The primary outcome was oligomenorrhoea/amenorrhoea. Secondary outcomes were hormones; anthropometry; quality of life; depression, anxiety and stress; pregnancy; birth outcomes; and safety. One hundred and twenty‐two women gave their consent.

    According to Indian Systems of Medicine, Mucuna pruriens Linn., belonging to the leguminous family (Papilionaceae), were used for treating male sexual disorders since ancient times. In this study, the effects of ethanolic extracts of the Mucuna pruriens Linn. seed on general mating behaviour, libido and potency of normal male Wister albino rats were investigated and also compared with the standard reference drug, Sildenafil citrate. Animals were divided into one control group (Group I--received saline) and four experimental groups (Groups II-V). Experimental groups were divided on the basis of the dosage of extract to the animals as follows: 150 mg/kg body weight (Group I), 200mg/kg body weight (Group II) and 250 mg/kg body weight (Group IV) while Group V received Sildenafil citrate (5mg/kg body weight). Animals were fed PO with saline or extract or standard drug once in a day for 45 days. To analyse the mating behaviour, female rats with oestrus phase were used. The extract administered PO significantly increased the mounting frequency, intromission frequency and ejaculation latency, and decreased the mounting latency, intromission latency, post-ejaculatory interval and inter-intromission interval. The potency test significantly increased erections, quick flips, long flips and total reflex. Therefore, the results indicated that the ethanolic extracts of Mucuna pruriens Linn. seed produced a significant and sustained increase in the sexual activity of normal male rats at a particular dose (200mg/kg). When compared to control, all the drug-treated groups have shown drug-induced effects for a few parameters. However in Group II, there was an obvious enhancement in all parameters, without affecting the normal behaviour. When compared with the standard drug, the net effect of extract is even less than that in Group II. Therefore, the resulting aphrodisiac activity of the extract lends support to the claim that it has traditionally been used for the treatment of sexual

    2001-10-01

    Ground licorice roots were exposed to 0, 5, 10, 15 and 20 kGy of gamma radiation in a 60 Co source. Irradiated and non-irradiated samples were stored at room temperature. Microbial population, viscosity, concentration of some minerals and sensory properties of the extract were evaluated after 0 and 12 months of storage. The results indicated that, immediately after irradiation, used doses reduced the microbial count and D 10 was at about 2 kGy. No effect was observed in total dissolved solids in the extract of licorice roots. Glycyrrhizinic acid concentration in extract and viscosity of suspension produced from irradiated roots were lower than in non-irradiated ones. Sensory evaluation indicated that no significant differences (P + , Ca ++ and K + ) concentration in extract produced from irradiated roots were lower than in non-irradiated ones, and no significant differences (P< 0.05) were found in viscosity between suspension of irradiated and non-irradiated roots.

    Chemical composition and biological (antimicrobial, antioxidant and cytotoxic) activities of essential oils (EO) obtained from the aerial parts of Glycyrrhiza triphylla Fisch. & C.A.Mey (G. triphylla) were evaluated in the present study. The EO was isolated and analyzed using gas chromatography-mass spectrometry (GC-MS). Fifty-five compounds representing 99.3% of the total oil composition were identified. Major components of the oil were β-caryophyllene (25.4%), limonene (16.7%), β-myrcene (16.0%) and α-humulene (4.4%). The oil composition was dominated by the presence of sesquiterpene hydrocarbons comprising 43.6% of the total oil. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the oil were determined against eight bacterial strains and one fungus. The EO showed a good antibacterial activity against both Gram-positive and Gram-negative bacteria. The most susceptible strain was Micrococcus luteus (MIC = 2.7 μg/mL, MBC = 43.6 μg/mL). The antioxidant potential of the EO was examined using DPPH and β-carotene/linoleic acid (BCB) assays. The oil was considerably active in the DPPH assay (IC 50  = 100.40 ± 0.03 μg/mL). Moreover, in vitro cytotoxic activity was assessed against six cancer cell lines using MTT assay. The EO showed no significant cytotoxic activity. In light of the present findings, G. triphylla oil may deserves to be further investigated for its potential therapeutic effects and also as a natural preservative in food industry.

    Over 60% of currently used anti-cancer agents are derived in one-way or another from natural sources, including plants, marine organisms and microorganisms. Calotropis gigantea (Linn.) (Family: Asclepiadaceae) is a perennial shrub and it is used as a traditional folk medicine for the treatment of various health complications. But there is no report on isolation of anticancerous chemicals from the flower of Calotropis gigantea. The objective of the present study is to explore the antitumor effect of anhydrosophoradiol-3-acetate (A3A), isolated from the flower of Calotropis gigantea (Linn.) against Ehrlich's ascites carcinoma (EAC) in Swiss albino mice. Antitumoric effect of A3A was assessed by evaluating viable tumor cell count, survival time, body weight gain due to tumor burden, hematological and biochemical (glucose, cholesterol, triglyceride, blood urea, SALP, SGPT and SGOT) parameters of EAC bearing host at doses of 10 and 20 mg/kg body weight. Treatment with A3A decreased the viable tumor cells and body weight gain thereby increasing the life span of EAC bearing mice. A3A also brought back the altered hematological (Hb, total RBC and total WBC) and biochemical parameters more or less to normal level. Results of this study conclude that in vivo the A3A was effective in inhibiting the growth of EAC with improving in cancer induced complications.

    2014-01-01

    Despite a number of traditional medicinal uses and pharmacological properties, the usefulness of Oxalis corniculata Linn. (Family: Oxalidaceae) is a question due to its high oxalate content which can form insoluble salts with physiological calcium. Therefore, the present study aimed to reduce oxalates in extracts and to investigate such extracts chemically and biologically. The extraction was carried out using different solvents and methods, and analytical studies of extracts indicated that oxalate contents decrease on drying the material. Furthermore, extraction of both fresh and dried materials using 1 % aqueous calcium chloride and ferric chloride solutions resulted in lowering oxalate contents. Methanolic extracts of stems and leaves having lower oxalates were obtained using sequential extraction, which showed good in vitro antioxidant activity - by DPPH and beta-carotene linoleate models - and in vivo hepatoprotective activity in isoniazid and rifampicin-induced oxidative stressed rats (P < 0.05). It was concluded that methanolic extracts of leaves and stems of Oxalis corniculata had lower oxalates and showed promising antioxidant and hepatoprotective activities. (author)

    TRANSPARENT TESTA GLABRA 1 of Arabidopsis thaliana (AtTTG1) is a WD40 repeat transcription factor that plays multiple roles in plant growth and development, particularly in seed metabolite production. In the present study, to determine whether SiTTG1 of the phylogenetically distant monocot foxtail millet (Setaria italica) has similar functions, we used transgenic Arabidopsis and Nicotiana systems to explore its activities. We found that SiTTG1 functions as a transcription factor. Overexpression of the SiTTG1 gene rescued many of the mutant phenotypes in Arabidopsis ttg1-13 plants. Additionally, SiTTG1 overexpression fully corrected the reduced expression of mucilage biosynthetic genes, and the induced expression of genes involved in accumulation of seed fatty acids and storage proteins in developing seeds of ttg1-13 plants. Ectopic expression of SiTTG1 restored the sensitivity of the ttg1-13 mutant to salinity and high glucose stresses during germination and seedling establishment, and restored altered expression levels of some stress-responsive genes in ttg1-13 seedlings to the wild type level under salinity and glucose stresses. Our results provide information that will be valuable for understanding the function of TTG1 from monocot to dicot species and identifying a promising target for genetic manipulation of foxtail millet to improve the amount of seed metabolites.

    Since antiquity, Piper betel Linn (betel vine; family Piperaceae) has been an important medicinal agent in the various traditional and folk systems of medicine in Southeast Asia countries. The leaves are the most valued plant part and in the past were routinely used as a chewing agent to prevent halitosis. The leaves are also supposed to harden the gum, conserve the teeth and to prevent indigestion, bronchitis, constipation, congestion, coughs and asthma. Innumerable scientific studies have validated the ethnomedicinal claims. Betel leaves are an integral component of the betel quid that consists of areca nut (Areca catechu Linn.), tobacco (Nicotiana tabacum L) and slaked lime; a highly abused agent with carcinogenic properties. Regular chewing of betel quid is associated mainly with oral cancer and detail studies with individual constituents of the quid have shown that both tobacco and areca nut are carcinogenic, while slaked lime is shown to promote the process of carcinogenesis. However unlike other constituents of the betel quid, the betel leaves devoid carcinogenic effects and on the contrary possesses cancer preventive effects including against the carcinogens present in tobacco. This review for the first time provides information on cancer preventive effects and also addresses the various mechanisms which might be involved.

    We previously reported that a methanol extract of Glycyrrhizae radix (MEGR) blocked methamphetamine-induced locomotor sensitization and conditioned place preference in rats. In the present study, the effects of MEGR on repeated nicotine-induced locomotor sensitization and enhanced extracellular dopamine (DA) release in the nucleus accumbens (Nacc) were evaluated. Male Sprague-Dawley rats received repeated administrations of nicotine (0.4 mg/kg, subcutaneous) or saline twice a day for 7 d and were challenged with nicotine 4 d after the last daily dosing. During the 4-d withdrawal period, the rats were treated once a day with MEGR (60 or 180 mg/kg/d). Extracellular DA levels were measured by in vivo microdialysis, the malondialdehyde levels and the activities of superoxide dismutase and catalase in the Nacc were biochemically evaluated, and the expression of antioxidant proteins was confirmed by Western blot assays. All data were assessed with analysis of variance tests followed by post-hoc comparison tests and p values nicotine-induced locomotor sensitization was dose-dependently attenuated by MEGR, and 180 mg/kg/d MEGR significantly inhibited augmented accumbal DA release induced by a direct local challenge of nicotine. Moreover, 180 mg/kg/d MEGR reversed increases in malondialdehyde production, decreases in superoxide dismutase and catalase activities, and the reduced expression of nuclear factor erythroid 2-related factor 2 and heme oxygenase 1 in the nicotine-sensitized Nacc. These results suggest that MEGR inhibited nicotine-induced locomotion and dopaminergic sensitization via antioxidant action.

    Concurrent use of herbs may mimic, magnify, or oppose the effect of drugs. Plausible cases of herb-drug interactions include: bleeding when warfarin is combined with ginkgo (Ginkgo biloba), garlic (Allium sativum), dong quai (Angelica sinensis), or danshen (Salvia miltiorrhiza); mild serotonin syndrome in patients who mix St John's wort (Hypericum perforatum) with serotonin-reuptake inhibitors; decreased bioavailability of digoxin, theophylline, cyclosporin, and phenprocoumon when these drugs are combined with St John's wort; induction of mania in depressed patients who mix antidepressants and Panax ginseng; exacerbation of extrapyramidal effects with neuroleptic drugs and betel nut (Areca catechu); increased risk of hypertension when tricyclic antidepressants are combined with yohimbine (Pausinystalia yohimbe); potentiation of oral and topical corticosteroids by liquorice (Glycyrrhiza glabra); decreased blood concentrations of prednisolone when taken with the Chinese herbal product xaio chai hu tang (sho-salko-to); and decreased concentrations of phenytoin when combined with the Ayurvedic syrup shankhapushpi. Anthranoid-containing plants (including senna [Cassia senna] and cascara [Rhamnus purshiana]) and soluble fibres (including guar gum and psyllium) can decrease the absorption of drugs. Many reports of herb-drug interactions are sketchy and lack laboratory analysis of suspect preparations. Health-care practitioners should caution patients against mixing herbs and pharmaceutical drugs.

    The species Pachyrrhizus erosus Linn., commonly known as yam bean, is cultivated in many countries for its edible underground tubers. The young tubers can be eaten raw, cooked, or can be sliced and made into chips. As genetic variability is limited in this species, a mutation breeding programme, using physical and chemical mutagens, was initiated to induce variability in a locally adapted cultivar. Genetically pure seeds were treated with concentrations of EMS ranging from 0.25 to 2%. Evaluation of M 2 raised from 1.25% treatment revealed a dwarf mutant showing a higher yield than the control. This mutant attained a height of 20 cm only in M 3 as against 82 cm in the controls. Though the starch content of the tuber and rotenone content in the seeds were the same as that in the control, protein content was slightly higher and the sugar content slightly less

    Full Text Available The patterning of the Arabidopsis root epidermis depends on a genetic regulatory network that operates both within and between cells. Genetic studies have identified a number of key components of this network, but a clear picture of the functional logic of the network is lacking. Here, we integrate existing genetic and biochemical data in a mathematical model that allows us to explore both the sufficiency of known network interactions and the extent to which additional assumptions about the model can account for wild-type and mutant data. Our model shows that an existing hypothesis concerning the autoregulation of WEREWOLF does not account fully for the expression patterns of components of the network. We confirm the lack of WEREWOLF autoregulation experimentally in transgenic plants. Rather, our modelling suggests that patterning depends on the movement of the CAPRICE and GLABRA3 transcriptional regulators between epidermal cells. Our combined modelling and experimental studies show that WEREWOLF autoregulation does not contribute to the initial patterning of epidermal cell fates in the Arabidopsis seedling root. In contrast to a patterning mechanism relying on local activation, we propose a mechanism based on lateral inhibition with feedback. The active intercellular movements of proteins that are central to our model underlie a mechanism for pattern formation in planar groups of cells that is centred on the mutual support of two cell fates rather than on local activation and lateral inhibition.

    Full Text Available Cola nitida Linn (Sterculiaceae is an economic plant widely distributed throughout West Africa and possibly other parts of Africa.Members are malvalves because of their lobular nature. Because of its ubiquity, the plant plays an important role in commerce, and in social activities where it is casually eaten without prescription or restriction. The ethnopharmacological effects of bolus ingestion of 30g of Cola nitida was investigated on visually acute and healthy volunteers in order to determine its ocular implications or effects. Results showed that Cola nitida had no effecton the pupil diameter, visual acuity and intraocular pressure but improved the near point of convergence by 43% and increased the amplitude of accommodation by 11% while existing heterophorias are ameliorated. The stimulating effect of Cola nitida might overcome asthenopic symptoms with convergence insufficiency and allows near work to be donewithout stress. Somnolence and ocular muscle imbalance common features of the elderly canbe ameliorated or relieved.

    Full Text Available ABSTRACT Phyllanthus emblica Linn. (amla is used in Ayurveda, the ancient Indian system of medicine and its major constituent is vitamin C which has effective free radical scavenging property. The purpose of this study was to evaluate the in vitro antioxidant activity and the bioavailability profile of vitamin C in amla and its combinations with piperine and ginger in comparison to synthetic vitamin C using New Zealand rabbits. In vitro antioxidant activity studies of synthetic vitamin C, amla, amla with piperine and amla with ginger were carried out using different models such as 2,2-Diphenyl-1-picrylhydrazyl, Nitric Oxide, Hydrogen peroxide scavenging methods, Total reductive capability and Oxygen Radical Absorbance Capacity estimation. The study results showed that synthetic vitamin C, amla, amla with piperine and amla with ginger possess significant in vitro antioxidant activity. For bioavailability studies, synthetic vitamin C, amla, amla with piperine and amla with ginger 100 mg/kg, were administered orally and the serum samples were analyzed by HPLC at 0, 1, 2, 3, 4, 6, 8, 10, 12 and 24 hours. Bioavailability studies revealed that amla with piperine combination has higher concentration of vitamin C when compared to synthetic vitamin C. This is probably due to presence of piperine, which is a bioavailability enhancer. The present study supports the fact that amla with piperine combination can be an alternative to synthetic vitamin C.

    Full Text Available Casuarina equisetifolia Linn. is an introduced actinorhizal plant grown as roadside ornamental tree and as forest plantation in Pakistan. Actinorhizal nodules are formed on the roots of C. equisetifolia as a response to infection by Frankia. Structure of C. equisetifolia nodules is described using histochemical methods to elucidate the nature of micro-symbiont within the nodules. C. equisetifolia nodules were similar to a root in general anatomical structure and resembled with Myrica-type nodules. The nodule consisted of a distinct periderm enclosing the cortex. The cortex showed patches of infected cells interspersed among uninfected ones. Inside the cortex there was a stele bounded by an endodermis, which contained tannins. The phloem-xylem relationship was amphicribral. A poorly defined meristem was also observed. Apart from simple nodules, dichotomously branched and coralloid nodules were also observed. The stele in simple and branched nodules reached up to the tip of the nodules. The micro-symbiont was observed in the nodule tissues in hyphal form only. The histochemical tests revealed absence of vacuoles and starch grains, and presence of tannins and lignin.

    The leaves of Morus alba Linn. (Family: Moraceae) commonly known as mulberry are mainly used as food for the silkworms and they are sometimes eaten as vegetable or used as cattle fodder in different parts of the world. The effect of Morus alba on the immune system was evaluated by using different experimental models such as carbon clearance test, cyclophosphamide induced neutropenia, neutrophil adhesion test, effect on serum immunoglobulins, mice lethality test and indirect haemagglutination test. Methanolic extract of Morus alba was administered orally at low dose and high dose of 100 mg/kg and 1 g/kg respectively and Ocimum sanctum (100 mg/kg, po) was used as standard drug. Morus alba extract in both doses increased the levels of serum immunoglobulins and prevented the mortality induced by bovine Pasteurella multocida in mice. It also increased the circulating antibody titre in indirect haemagglutination test. On the other hand, it showed significant increase in the phagocytic index in carbon clearance assay, a significant protection against cyclophosphamide induced neutropenia and increased the adhesion of neutrophils in the neutrophil adhesion test. Hence, it was concluded that Morus alba increases both humoral immunity and cell mediated immunity.

    This study was aimed at investigating the antimelanogenic and antioxidative properties of the essential oil extracted from leaves of V. negundo Linn and the analysis of the chemical composition of this essential oil. The efficacy of the essential oil was evaluated spectrophotometrically, whereas the volatile chemical compounds in the essential oil were analyzed by gas chromatography-mass spectrometry (GC-MS). The results revealed that the essential oil effectively suppresses murine B16F10 tyrosinase activity and decreases the amount of melanin in a dose-dependent manner. Additionally, the essential oil significantly scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radicals, and showed potent reducing power versus metal-ion chelating properties in a dose-dependent pattern. The chemical constituents in the essential oil are sesquiterpenes (44.41%), monoterpenes (19.25%), esters (14.77%), alcohols (8.53%), aromatic compound (5.90%), ketone (4.96%), ethers (0.4%) that together account for 98.22% of its chemical composition. It is predicted that the aromatic compound in the essential oil may contribute to its antioxidant activities. The results indicated that essential oil extracted from V. negundo Linn leaves decreased melanin production in B16F10 melanoma cells and showed potent antioxidant activities. The essential oil can thereby serve as an inhibitor of melanin synthesis and could also act as a natural antioxidant.

    Plaque-associated gingivitis is a prevalent disease and research in its treatment using herbal agents must be encouraged to verify which would be a useful addition to the current range or chemotherapeutic treatment options. The aim of this study was to evaluate the clinical effect of a mouth rinse containing 10% Anacardium occidentale (AO) Linn., a typical plant commonly found in the Northeast Region of Brazil, on the reduction of plaque and gingivitis in comparison to a gold-standard chemotherapeutic agent. Thirty normosystemic adult volunteers of both genders, who had a minimum of twenty natural teeth, aging between 18 and 32 years, were enrolled in this crossover, controlled, examiner-blind clinical study. They were randomly allocated into three groups: 10% AO Linn. (n = 10); 0.12% chlorhexidine digluconate (CLX, n = 10); or placebo (PB, n = 10). All volunteers were instructed to brush their teeth with a fluoridated dentifrice two times a day (12/12 h) and to rinse for 1 min with one of the mouthwashes (AO, CLX, or PB) 30 min after tooth brushing for 1 month. Plaque index (PLI) and gingival bleeding index (BLI) were recorded on days 0 and 30. Nonparametric Kruskal-Wallis and Wilcoxon tests (α = 0.05) were performed to evaluate statistical differences among groups. There was a significant reduction (P gingivitis at day 30 just in CLX ([PLI = 0.47 ± 0.16; -30%]; [BLI = 0.15 ± 0.09; -55.8%]) and AO ([PLI = 0.49 ± 0.21; -31%]; [BLI = 0.13 ± 0.10; -56.6%]) groups, but no statistically significant difference was observed among them (P > 0.05). Mouthwash containing 10% AO was effective as an antiplaque and antigingivitis agent, in a similar manner that 0.12% CLX.

    This study was conducted to determine effect and mechanism of exogenous silicon (Si) on salt and drought tolerance of Glycyrrhiza uralensis seedling by focusing on the pathways of antioxidant defense and osmotic adjustment. Seedling growth, lipid peroxidation, antioxidant metabolism, osmolytes concentration and Si content of G. uralensis seedlings were analyzed under control, salt and drought stress [100 mM NaCl with 0, 10 and 20% of PEG-6000 (Polyethylene glycol-6000)] with or without 1 mM Si. Si addition markedly affected the G. uralensis growth in a combined dose of NaCl and PEG dependent manner. In brief, Si addition improved germination rate, germination index, seedling vitality index and biomass under control and NaCl; Si also increased radicle length under control, NaCl and NaCl-10% PEG, decreased radicle length, seedling vitality index and germination parameters under NaCl-20% PEG. The salt and drought stress-induced-oxidative stress was modulated by Si application. Generally, Si application increased catalase (CAT) activity under control and NaCl-10% PEG, ascorbate peroxidase (APX) activity under all treatments and glutathione (GSH) content under salt combined drought stress as compared with non-Si treatments, which resisted to the increase of superoxide radicals and hydrogen peroxide caused by salt and drought stress and further decreased membrane permeability and malondialdehyde (MDA) concentration. Si application also increased proline concentration under NaCl and NaCl-20% PEG, but decreased it under NaCl-10% PEG, indicating proline play an important role in G. uralensis seedling response to osmotic stress. In conclusion, Si could ameliorate adverse effects of salt and drought stress on G. uralensis likely by reducing oxidative stress and osmotic stress, and the oxidative stress was regulated through enhancing of antioxidants (mainly CAT, APX and GSH) and osmotic stress was regulated by proline.

    Full Text Available The combined cytoactive effects of American ginseng (Panax quinquefolius and licorice (Glycyrrhiza uralensis root extracts were investigated in a hepatocarcinoma cell line (Hep-G2. An isobolographic analysis was utilized to express the possibility of synergistic, additive or antagonistic interaction between the two extracts. Both ginseng and licorice roots are widely utilized in traditional Chinese medicine preparations to treat a variety of ailments. However, the effect of the herbs in combination is currently unknown in cultured Hep-G2 cells. Ginseng (GE and licorice (LE extracts were both able to reduce cell viability. The LC50 values, after 72 h, were found to be 0.64 ± 0.02 mg/mL (GE and 0.53 ± 0.02 mg/mL (LE. An isobologram was plotted, which included five theoretical LC50s calculated, based on the fixed fraction method of combination ginseng to licorice extracts to establish a line of additivity. All combinations of GE to LE (1/5, 1/3, 1/2, 2/3, 4/5 produced an effect on Hep-G2 cell viability but they were all found to be antagonistic. The LC50 of fractions 1/3, 1/2, 2/3 were 23%, 21% and 18% above the theoretical LC50. Lactate dehydrogenase release indicated that as the proportion of GE to LE increased beyond 50%, the influence on membrane permeability increased. Cell-cycle analysis showed a slight but significant arrest at the G1 phase of cell cycle for LE. Both GE and LE reduced Hep-G2 viability independently; however, the combinations of both extracts were found to have an antagonistic effect on cell viability and increased cultured Hep-G2 survival.

    Full Text Available Abstract Background Blechnum orientale Linn. (Blechnaceae is used ethnomedicinally to treat wounds, boils, blisters or abscesses and sores, stomach pain and urinary bladder complaints. The aim of the study was to validate the ethnotherapeutic claim and to evaluate the effects of B. orientale water extract on wound healing activity. Methods Water extract of B. orientale was used. Excision wound healing activity was examined on Sprague-Dawley rats, dressed with 1% and 2% of the water extract. Control groups were dressed with the base cream (vehicle group, negative control and 10% povidone-iodine (positive control respectively. Healing was assessed based on contraction of wound size, mean epithelisation time, hydroxyproline content and histopathological examinations. Statistical analyses were performed using one way ANOVA followed by Tukey HSD test. Results Wound healing study revealed significant reduction in wound size and mean epithelisation time, and higher collagen synthesis in the 2% extract-treated group compared to the vehicle group. These findings were supported by histolopathological examinations of healed wound sections which showed greater tissue regeneration, more fibroblasts and angiogenesis in the 2% extract-treated group. Conclusions The ethnotherapeutic use of this fern is validated. The water extract of B. orientale is a potential candidate for the treatment of dermal wounds. Synergistic effects of both strong antioxidant and antibacterial activities in the extract are deduced to have accelerated the wound repair at the proliferative phase of the healing process.

    Previous studies have shown that GLABRA3 (AtGL3), a bHLH transcription factor, plays essential roles in anthocyanin biosynthesis and trichome formation in Arabidopsis thaliana. However, there have been no such studies of a homologue, BnGL3, from the closely related crop, Brassica napus. Here, we analysed the BnGL3-1 coding domain sequence from the B. napus cultivar QINYOU Seven, identified conserved protein domains and performed a phylogenetic analysis to elucidate its relationship with homologues form a range of plant species. When expressed in tobacco leaves as a fusion protein with green fluorescent protein, BnGL3-1 accumulated in the nucleus, consistent with its predicted function as a transcription factor. Ectopic expression of the BnGL3-1 gene in the A. thaliana gl3-3 mutant resulted in levels of anthocyanins and numbers of trichomes in true leaves that were higher than in wild-type plants. Moreover, overexpression of BnGL3-1 in gl3-3 compensated for the promotion and repression of genes involved in anthocyanin biosynthesis and trichome formation, respectively, that has been reported in gl3-3 young shoots and expanding true leaves. This study provides new insights into GL3 function in anthocyanin biosynthesis and trichome formation in crucifers, and represents a promising target for genetic manipulation of B. napus. © 2017 German Society for Plant Sciences and The Royal Botanical Society of the Netherlands.

    Angelica archangelica Linn. is widely used in food and liquor preparations and also in Kashmiri folk medicine to reduce anxiety. We evaluated the anxiolytic effect of successive extracts of A. archangelica linn. (SAE) on rats tested in the elevated T-maze test (an animal model of generalized anxiety) at doses that exhibit antidepressant-like activity in humans. A. archangelica (1 kg) was subjected to successive extraction in a soxhlet apparatus with solvents [petroleum ether (40-60 degrees C), chloroform, ethyl acetate, methanol and decoction with water] in order of increasing polarity (yield: 6.9%, 7.3%, 5.1%, 11.88% and 8.2% w/w, respectively). SAE were evaluated for anxiolytic effects using the elevated T-maze and forced swimming tests in rats. Oral dosing of diazepam (1 mg/kg) and extracts (50, 100 and 200 mg/kg) clearly showed an anxiolytic-like profile in the elevated T-maze test: it increased one-way escape and decreased inhibitory avoidance on the first, third and seventh day. In the forced swimming test, imipramine and SAE showed antidepressant- and anxiolytic-like effects as reflected by increased climbing time, swimming time and decreased immobility time on the first, third and seventh day. Aqueous and methanol extracts showed the most, petroleum ether (40-60 degrees C) and chloroform intermediate, and ethyl acetate the least anxiolytic activity (*P<0.05, **P<0.01, ***P< 0.001) in both models. These results suggest the anti-anxiety activity of various extracts of A. archangelica and strongly justify its use in traditional Indian medicine for the treatment of anxiety.

    Schisandra chinensis (Chinese starvine) is a popular dietary supplement with a rich history of use in traditional Chinese medicine. Schisandra glabra (bay starvine) is the only North American representative of the genus, and little is known about its history of traditional use, chemistry, and potential biological activity. In this study, we conducted comparative high-performance liquid chromatography-diode array detector (HPLC-DAD) analysis on S. glabra and S. chinensis fruits. Additional characterization of S. glabra was performed by liquid chromatography-Fourier transform mass spectrometry (LC-FTMS). Quantitative analysis of four bioactive marker compounds revealed that S. glabra does not have statistically higher levels of schisandrin A or schisandrol B than S. chinensis. S. glabra has lower levels of schisandrol A and γ-schisandrin. Total phenolic contents of the two species' fruits were not statistically different. S. glabra had higher total tannin content than S. chinensis. We discuss the relevance of this analytical analysis to the study of S. glabra as a potential dietary supplement ingredient and give specific consideration to the conservation challenges involved in commercially developing a regionally threatened species, even in semicultivated conditions.

    In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

    Full Text Available This study was aimed at investigating the antimelanogenic and antioxidative properties of the essential oil extracted from leaves of V. negundo Linn and the analysis of the chemical composition of this essential oil. The efficacy of the essential oil was evaluated spectrophotometrically, whereas the volatile chemical compounds in the essential oil were analyzed by gas chromatography-mass spectrometry (GC-MS. The results revealed that the essential oil effectively suppresses murine B16F10 tyrosinase activity and decreases the amount of melanin in a dose-dependent manner. Additionally, the essential oil significantly scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH and 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid (ABTS radicals, and showed potent reducing power versus metal-ion chelating properties in a dose-dependent pattern. The chemical constituents in the essential oil are sesquiterpenes (44.41%, monoterpenes (19.25%, esters (14.77%, alcohols (8.53%, aromatic compound (5.90%, ketone (4.96%, ethers (0.4% that together account for 98.22% of its chemical composition. It is predicted that the aromatic compound in the essential oil may contribute to its antioxidant activities. The results indicated that essential oil extracted from V. negundo Linn leaves decreased melanin production in B16F10 melanoma cells and showed potent antioxidant activities. The essential oil can thereby serve as an inhibitor of melanin synthesis and could also act as a natural antioxidant.

    2013-01-01

    Full Text Available Formononetin is a naturally occurring isoflavone, which can be found in low concentrations in many dietary products, but the greatest sources of this substance are Astragalus membranaceus, Trifolium pratense, Glycyrrhiza glabra, and Pueraria lobata, which all belong to Fabaceae family. Due to its structural similarity to 17β-estradiol, it can mimic estradiol’s effect and therefore is considered as a “phytoestrogen.” The aim of this study was to examine the effect of formononetin on mechanical properties and chemical composition of bones in rats with ovariectomy-induced osteoporosis. 12-week-old female rats were divided into 4 groups: sham-operated, ovariectomized, ovariectomized treated with estradiol (0.2 mg/kg and ovariectomized treated with formononetin (10 mg/kg. Analyzed substances were administered orally for 4 weeks. Ovariectomy caused osteoporotic changes, which can be observed in bone biomechanical features (decrease of maximum load and fracture load and increase of displacements for maximum and fracture loads and bone chemical composition (increase of water and organic fraction content, while a decrease of minerals takes place. Supplementation with formononetin resulted in slightly enhanced bone mechanical properties and bone chemistry improvement (significantly lower water content and insignificantly higher mineral fraction content. To summarize, administration of formononetin to ovariectomized rats shows beneficial effect on bone biomechanical features and chemistry; thus, it can prevent osteoporosis development.

    Land plant plastid genomes (plastomes) provide a tractable model for evolutionary study in that they are relatively compact and gene dense. Among the groups that display an appropriate level of variation for structural features, the inverted-repeat-lacking clade (IRLC) of papilionoid legumes presents the potential to advance general understanding of the mechanisms of genomic evolution. Here, are presented six complete plastome sequences from economically important species of the IRLC, a lineage previously represented by only five completed plastomes. A number of characters are compared across the IRLC including gene retention and divergence, synteny, repeat structure and functional gene transfer to the nucleus. The loss of clpP intron 2 was identified in one newly sequenced member of IRLC, Glycyrrhiza glabra. Using deeply sequenced nuclear transcriptomes from two species helped clarify the nature of the functional transfer of accD to the nucleus in Trifolium, which likely occurred in the lineage leading to subgenus Trifolium. Legumes are second only to cereal crops in agricultural importance based on area harvested and total production. Genetic improvement via plastid transformation of IRLC crop species is an appealing proposition. Comparative analyses of intergenic spacer regions emphasize the need for complete genome sequences for developing transformation vectors for plastid genetic engineering of legume crops. © 2014 Society for Experimental Biology, Association of Applied Biologists and John Wiley & Sons Ltd.

    Herbal liqueurs are alcoholic beverages produced by the maceration or distillation of aromatic and medicinal plants in alcohol, and are also highly valued for their medicinal properties. The process conditions, as well as the number and quantity of the plants employed, will have a great influence on the quality of the liqueur obtained. The aim of this research was to optimize these important variables. A Box-Benhken experimental design was used to evaluate the independent variables: alcohol content, amount of plant and time during the experimental maceration of plants in grape marc distillate. Four plants were assessed, with the main compound of each plant representing the dependent variable evaluated with respect to following the evolution of the maceration process. Bisabolol oxide A in Matricaria recutita L., linalool in Coriander sativum L. and eucalyptol in Eucalyptus globulus Labill. were quantified using a gas chromatography-flame ionization detector. Glycyrrhizic acid in Glycyrrhiza glabra L was determined using a high-performance liquid chromatography-diode array detector. Other dependent variables were also evaluated: total phenolic content, color parameters and consumer preference (i.e. appearance). The experimental designs allowed the selection of the optimal maceration conditions for each parameter, including the preference score of consumers: 70% (v/v) of ethanol, 40 g L -1 plant concentration and a maceration process of 3 weeks. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Metabolic syndrome is a serious health problem in the present world. Glycyrrhizin, a triterpenoid saponin of licorice (Glycyrrhiza glabra) root, has been reported to ameliorate the primary complications and hepatocellular damage in rats with the syndrome. In this study, we have explored metabolic syndrome-induced changes in liver mitochondrial function and effect of glycyrrhizin against the changes. Metabolic syndrome was induced in rats by high fructose (60%) diet for 6 weeks. The rats were then treated with glycyrrhizin (50 mg/kg body weight) by single intra-peritoneal injection. After 2 weeks of the treatment, the rats were sacrificed to collect liver tissue. Elevated mitochondrial ROS, lipid peroxidation and protein carbonyl, and decreased reduced glutathione content indicated oxidative stress in metabolic syndrome. Loss of mitochondrial inner membrane cardiolipin was observed. Mitochondrial complex I activity did not change but complex IV activity decreased significantly. Mitochondrial MTT reduction ability, membrane potential, phosphate utilisation and oxygen consumption decreased in metabolic syndrome. Reduced mitochondrial aconitase activity and increased aconitase carbonyl content suggested oxidative damage of the enzyme. Elevated Fe(2+) ion level in mitochondria might be associated with increased ROS generation in metabolic syndrome. Glycyrrhizin effectively attenuated mitochondrial oxidative stress and aconitase degradation, and improved electron transport chain activity. Copyright © 2016 John Wiley & Sons, Ltd.

    The bark extract of Abroma augusta Linn is rich in medicinally important phytochemicals including antioxidants and polyphenols. First one step green synthesis of gold nanoparticles (AuNPs) has been described utilizing the bark extract of Abroma augusta L. and chloroauric acid under very mild reaction conditions. The phytochemicals present in the bark extract acted both as a reducing as well as a stabilizing agent, and no additional stabilizing and capping agents were needed. Detailed characterizations of the stabilized AuNPs were carried out by surface plasmon resonance spectroscopy, high resolution transmission electron microscopy, and X-ray diffraction studies. The catalytic activity of the freshly synthesized gold nanoparticles has been demonstrated for the sodium borohydride reduction of 4-nitrophenol to 4-aminophenol, and the kinetics of the reduction reaction have been studied spectrophotometrically.

    Habitat fragmentation, water resources and biological characteristics are important factors that shape the genetic structure and geographical distribution of desert plants. Analysis of the relationships between these factors and population genetic variation should help to determine the evolutionary potential and conservation strategies for genetic resources for desert plant populations. As a traditional Chinese herb, Glycyrrhiza inflata B. (Fabaceae) is restricted to the fragmented desert habitat in China and has undergone a dramatic decline due to long-term over-excavation. Determining the genetic structure of the G. inflata population and identifying a core collection could help with the development of strategies to conserve this species. We investigated the genetic variation of 25 G. inflata populations based on microsatellite markers. A high level of population genetic divergence (FST = 0.257), population bottlenecks, reduced gene flow and moderate genetic variation (HE = 0.383) were detected. The genetic distances between the populations significantly correlated with the geographical distances, and this suggests that habitat fragmentation has driven a special genetic structure of G. inflata in China through isolation by distance. STRUCTURE analysis showed that G. inflata populations were structured into three clusters and that the populations belonged to multiple water systems, which suggests that water resources were related to the genetic structure of G. inflata. In addition, the biological characteristics of the perennial species G. inflata, such as its long-lived seeds, asexual reproduction, and oasis ecology, may be related to its resistance to habitat fragmentation. A core collection of G. inflata, that included 57 accessions was further identified, which captured the main allelic diversity of G. inflata. Recent habitat fragmentation has accelerated genetic divergence. The population genetic structure of G. inflata has been shaped by habitat

    Full Text Available Fruits are important sources of nutrients in human diet, and Barbados Cherry (Malpighia glabra L. is of particular interest due to its high content of antioxidants. Diets rich in fruits and vegetables protect individuals against diseases and cancer, but excessive intake of vitamins may act as pro-oxidant and generate changes in DNA. To evaluate the effect of different in natura (BAN and frozen (BAF Barbados Cherry pulp concentrations and synthetic vitamin C in liquid form (VC on the chromosome level and the cell cycle division, root meristeme cells of Allium cepa L. and bone marrow cells of Wistar rats Rattus norvegicus, were used as test system. In Allium cepa L., BAN, at the highest concentration (0.4 mg.mL-1 and BAF, at the lowest concentration (0.2 mg.mL-1, inhibited cell division, and there was recovery of cell division after the recovery period in water only for BAN. In the Wistar rats, all treatments with Barbados Cherry, either acute or subchronic, were not cytotoxic or mutagenic; only the highest concentration of VC increased significantly the rate of chromosomal abnormalities. The data obtained are important to reinforce the use of Barbados Cherry fruit in the diet.

    Full Text Available Human and veterinary medicines have not been so well succeeded in order to achieving their goals concerning the treatment of infections for long term caused by Staphylococcus aureus linked to resistance development against antibiotic agents. The antibiotic activity of the Punica granatum Linn. fresh fruit pericarp extract was evaluated by the agar diffusion method on 38 S. aureus strains, isolated from apparently healthy lactating cows in farms situated in counties of the semi-arid region of the State of Paraíba, Brazil to determine the minimum inhibitory concentration (MIC. Twenty-two of the thirty-eight strains are penicillin-resistant (PRSA.

    Plant materials rich in phenolic compounds, such as Anacardium occidentale Linn., Have been used as alternatives to synthetic pesticides in Biomphalaria glabrata control programs, intermediate host of Schistosoma mansoni. Studies show that ionizing radiation can influence the content of phenolic compounds and thus their biological actions. The aim of this study was to evaluate the influence of gamma radiation of 60 Co in polyphenol composition of hydroalcoholic extracts of bark and leaves of A. occidentale and evaluate the toxicity of these extracts to embryos and adults of B. glabrata. To achieve this goal this, the extracts were irradiated at 10 kGy, the controls being maintained from 0 kGy and positive (CaCO 3 ) and negative (H 2 O). We quantified the total phenols by the Folin-Ciocalteau and tannins by precipitation of casein. Extracts were used at a concentration of 100 mg/L. The results showed that the radiation caused the changes to the leaves, the percentage of polyphenols and tannins, and the percentage of lethality in embryos and adults Biomphalaria glabrata, these percentages being: 13 ± 5 (0 kGy) and 27 ± 2.5 (10 kGy), and 36.67 ± 5.77 (0 kGy), and 56.67 ± 5.77 (10 kGy), respectively. Gamma radiation caused significant changes in the levels of polyphenols in the extracts of leaves of Anacardium ocidentale Linn., translated by the increased toxicity of this extract against embryos and adults of Biomphalaria glabrata. This indicates that gamma radiation can be used as an agent potentiating the toxicity of plant extracts on the alternate use of these materials as molluscicides. (author)

    A facile one-step green synthesis of stable gold nanoparticles (AuNPs) has been described using chloroauric acid (HAuCl4) and the leaf extract of Lantana camara Linn (Verbenaceae family) at room temperature. The leaf extract enriched in various types of plant secondary metabolites is highly efficient for the reduction of chloroaurate ions into metallic gold and stabilizes the synthesized AuNPs without any additional stabilizing or capping agents. Detailed characterizations of the synthesized gold nanoparticles were carried out by surface plasmon resonance spectroscopy, transmission electron microscopy, dynamic light scattering, Zeta potential, X-ray diffraction and Fourier transform-infrared spectroscopy studies. The synthesized AuNPs have been utilized as a catalyst for the sodium borohydride reduction of 4-nitrophenol to 4-aminophenol in water at room temperature under mild reaction condition. The kinetics of the reduction reaction has been studied spectrophotometrically.

    The fruit of Cassia fistula Linn. is a legume, has antioxidant and lots of other medicinal properties. As oxidants are involved in the pathogenesis of chronic fatigue syndrome, the present study was done to evaluate the effect of ethanolic extract of fruit pulp of C. fistula Linn. (EECF) on forced swimming induced chronic fatigue syndrome (CFS). Albino mice of 25-40 grams were grouped into five groups (n=5). Group A served as naive control and group B served as stress control. Group C received EECF 200 mg/kg and group D received EECF 400 mg/kg respectively. Group E received imipramine 20 mg/kg (standard). All animals were treated with their respective agent orally daily for 7 days. Except for group A, animals in other groups were subjected to force swimming 6 min daily for 7 days to induce a state of chronic fatigue. Duration of immobility was assessed on day 1(st), 3(rd), 5(th) and 7(th). Anxiety level (by elevated plus maze and mirrored chamber) and loco-motor activity (by open field test) were assessed 24 h after last force swimming followed by biochemical estimations of oxidative biomarkers in brain homogenate at the end of study. Treatment with EECF resulted in significant reduction in the duration of immobility, reduced anxiety and increased loco-motor activity. Malondialdehyde level was also reduced and catalase level was increased in the extract treated group and standard group compared to stress control group. The study indicates that EECF has protective effect against experimentally induced CFS.

    A medicinal herb Tribulus terrestris Linn has been used to treat various diseases including hepatocellular carcinoma. The aim of the present study was to investigate the anticancer activity of Tribulus terrestris Linn (TT) in liver cancer cells. The antitumor activity of aqueous TT extract was analyzed by testing the cytotoxicity and the effect on clonogenecity in HepG2 cells. Apoptosis and cell cycle arrest induced by TT were dissected by flow cytometry and its inhibitory effect on NF-κB activity was determined by analyzing the expression levels of NF-κB/IκB subunit proteins. The suppression of NF-κB-regulated gene expression by TT was assessed by RT-PCR. TT extract repressed clonogenecity and proliferation, induced apoptosis, and enhanced accumulation in the G0/G1 phase of liver cancer cells. It also turned out that TT extract inhibited NF-κB-dependent reporter gene expression and NF-κB subunit p50 expression, while it enhanced the cellular level of IκBα by inhibiting the phosphorylation and degradation of IκBα. In addition, IKK activity was inhibited in a dose-dependent manner. Furthermore, TT extract suppressed the transcription of genes associated with cell cycle regulation, anti-apoptosis, and invasion. These data showed that TT extract blocks proliferation and induces apoptosis in human liver cancer cells through the inhibition of NF-κB signaling. Aqueous TT extract can be used as an anticancer drug for hepatocellular carcinoma patients. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The petroleum ether, chloroform, methanol, and aqueous extracts of Heliotropium indicum Linn. (Family: Boraginaceae) were separately evaluated for their wound healing activity in rats using excision (normal and infected), incision, and dead space wound models. The effects of test samples on the rate of wound healing were assessed by the rate of wound closure, period of epithelialisation, wound breaking strength, weights of the granulation tissue, determination of hydroxyproline, super oxide dismutase (SOD), catalase, and histopathology of the granulation tissues. Nitrofurazone (0.2% w/w) in simple ointment I. P. was used as reference standard for the activity comparison. The results revealed significant promotion of wound healing with both methanol and aqueous extracts with more promising activity with the methanol extract compared to other extracts under study. In the wound infection model (with S. aureus and P. aeruginosa), the methanol extract showed significant healing activity similar to the reference standard nitrofurazone. Significant increase in the granulation tissue weight, increased hydroxyproline content, and increased activity of SOD and catalase level with the animals treated with methanol extract in dead space wound model further augmented the wound healing potential of H. indicum. The present work substantiates its validity of the folklore use.

    Full Text Available Summary Polygalacturonases are enzymes with the biotechnological potential for use in fruit juice clarification and for the enhancement of filtration efficiency. The aim of this work was to assess the production of polygalacturonase by the fungus Neosartorya glabra by means of solid-state and submerged fermentation using fruit peel residues as the carbon source, and also apply the enzyme in the clarification and decrease in viscosity of passion fruit and apple juices. The highest polygalacturonase (4.52 U/g/h production was obtained by means of submerged fermentation in Vogel´s medium (1964 containing orange peel – Bahia variety (Citrus sinensis, at a concentration of 1.5% (w/v, dried mass at 30-35°C for 72 h. The polygalacturonase of the crude extract presented optimal activity at 60°C and pH 5.5. The enzyme retained around 90% of the initial activity after 180 minutes at 40°C, and 50% of the initial activity after 150 minutes at 50°C. The enzyme was shown to be stable at acid pH values (3.0-6.5 after 120 minutes at 25oC. All these favourable enzymatic properties make the polygalacturonase attractive for potential uses in the industry of pectin-rich fruit juices, since the application of the crude extract to passion fruit (Passiflora edulis juice caused an 80% reduction in viscosity and 75% decrease in light absorbance. In the processing of apple pulp juice (Malus domestica, there was a 50% reduction in viscosity and 78% decrease in light absorbance.

    Full Text Available In the present study, a goldfish (Carassius auratus Linn. recirculating aquaculture system (GRAS has been developed. The GRAS consisted of a culture tank, a screen filter and a foam fractionator for removal of particulate and dissolved solids and a trickling filter for conversion of ammonium- and nitrite-nitrogen to relatively harmless nitrate-nitrogen. The culture of goldfish at a stocking density of 1.08 kg/m3 was continued for a period of two and half months. Based on mass balance analysis of ammonium- and nitrate-nitrogen and assuming the trickling filter to be a plug flow reactor, a model was formulated to determine the necessary recirculation flow rate at different times of culture for maintaining the major nutrients, viz., ammonium- and nitrate-nitrogen below their permissible limits. The model was calibrated and validated using the real time data obtained from the experimental run. The high values of coefficient of determination and low values of root mean square error show the effectiveness of the model.

    Piper betle Linn. (Piperaceae) is used as a remedy for gastric ulcers in traditional medicinal systems in Sri Lanka. However, the gastroprotective activity has never been proven scientifically using betel leaves grown in Sri Lanka. To evaluate the gastroprotective activity of hot aqueous extract (HAE) and cold ethanolic extract (CEE) of P. betle in rats as the experimental model. Three doses (200, 300, and 500 mg/kg/bw) of both extracts were evaluated for the gastroprotective activity against ethanol induced gastric ulcers in rats. The parameters evaluated were (a) effects of HAE on mucus content adhering to the wall of the gastric mucosa, (b) acidity (total and free), (c) volume and (d) pH of the gastric juice. ORAL ADMINISTRATION OF HAE AND CEE PROVIDED MARKED DOSE DEPENDENT (HAE: r (2) = 0.97; CEE: r (2) = 0.96) and significant (P ≤ 0.05) protection against gastric damage caused by absolute ethanol. The gastroprotective effect of CEE was comparable with that of HAE. Further, gastroprotective activity of the highest dose of both extracts were significantly greater (P ≤ 0.05) than that of misoprostol, the reference drug. The HAE significantly (P ≤ 0.05) increased the mucus content adhering to the wall of the gastric mucosa and inhibited the volume of gastric acid. However, acidity (total and free) and pH of the gastric juice remained unaltered. It is concluded that both HAE and CEE of P. betle leaves have a strong gastroprotective activity.

    Three type of ground root of licorice (fine particular 8.0 mm diameter) were divided into two groups, the first one was exposed to 0, 5, 10, 15 and 20 kGy. Whereas, the second group was exposed 0, 25, 50, 75, and 100 kGy of gamma radiation from a 60 Co source. Irradiated and non-irradiated samples were stored at room temperature. Microbial population, concentrations of glycyrrhizinic acid and some minerals of the extracts were evaluated after irradiation. The results showed that microbial count on fine particular of ground licorice roots were 10 6 g -1 , whereas, on coarse particular microbial counts was 10 5 g -1 . All size of licorice roots treated with gamma irradiation had significantly (p<0.05) lower counts than the untreated (control). The dose needed to reduce the microbial load to less than 10 bacteria per gram was 15 kGy for the fine particular of ground root, and 10 kGy for the coarse particular of ground root. The extract produced from coarse particular of ground roots had lower total dissolved solids, ash and mineral ions (Na, Ca, and K), ph, and Ec values compared with those produced from coarse particular of ground roots. Gamma irradiation decreased glycyrrhizinic acid concentrations in the extracts produced from ground licorice roots. High doses (25, 50, 75, and 100 kGy) of gamma irradiation decreased significantly the concentration of raw fiber, and glycyrrhizinic acid concentrations on ground licorice roots, and increased the dissolved solids and mineral ions (Na, Ca, and K) in extract of licorice root. Sensory evaluation indicated that there were no significant differences in colour, taste or flavour between extracts produced from irradiated with doses up to 25 kGy and non-irradiated roots.

    Marsilea minuta Linn. (Marsileaceae) has been referred in Indian traditional medicine system (Ayurveda) for the treatment of insomnia and other mental disorders. Marsiline isolated from Marsilea minuta was reported to have sedative and anticonvulsant property. The ethanol extract of Marsilea minuta was standardised for marsiline (1.15%, w/w) and studied for its antidepressant activity. Antidepressant activity was studied using forced swimming test (FST), tail suspension test (TST), learned helplessness test (LHT) and 5-hydroxytryptophan (5-HTP) induced head twitches response in rodents. Standardised extract of Marsilea minuta in doses of 100, 200 and 400 mg/kg/day were administered orally for three consecutive days and evaluated on day 3, 1h after the last dose treatment. Imipramine (15 mg/kg/day, i.p.) was used as the standard drug. Neurochemical mechanism of antidepressant activity was elucidated by using radioligand receptor binding assays for 5-HT2A and benzodiazepine receptors in rat frontal cortex. Immobility time in FST and TST was significantly (P<0.05) reduced by ethanol extract of Marsilea minuta treated animals. A decrease in number of escape failures in LHT was also observed in Marsilea minuta treated rats. Head twitch response induced by 5-HTP was significantly attenuated by Marsilea minuta (400 mg/kg, p.o.) and imipramine showing the involvement of serotonergic system. This effect was corroborated with radioligand receptor binding study where Marsilea minuta (400 mg/kg, p.o.) significantly (P<0.05) down regulated 5-HT2A receptor in frontal cortex, whereas, no marked effect was observed for benzodiazepine receptor. The antidepressant effect exhibited by Marsilea minuta extract may be due to its effect on 5-HT2A density in rat frontal cortex.

    The available therapy for leishmaniasis, which affects 2 million people per annum, still causes serious side effects. The polyphenolic-rich extract from the husk fiber of Cocos nucifera Linn. (Palmae) presents antibacterial and antiviral activities, also inhibiting lymphocyte proliferation, as shown by our group in previous works. In the present study, the in vitro leishmanicidal effects of C. nucifera on Leishmania amazonensis were evaluated. The minimal inhibitory concentration of the polyphenolic-rich extract from C. nucifera to completely abrogate parasite growth was 10 microg/ml. Pretreatment of peritoneal mouse macrophages with 10 microg/ml of C. nucifera polyphenolic-rich extract reduced approximately 44% the association index between these macrophages and L. amazonensis promastigotes, with a concomitant increase of 182% in nitric oxide production by the infected macrophage in comparison to nontreated macrophages. These results provide new perspectives on drug development against leishmaniasis, since the extract of C. nucifera at 10 microg/ml is a strikingly potent leishmanicidal substance which inhibited the growth of both promastigote and amastigote developmental stages of L. amazonensis after 60 min, presenting no in vivo allergenic reactions or in vitro cytotoxic effects in mammalian systems.

    In the present study, the culture conditions for the accumulation of Glycyrrhiza uralensis adventitious root metabolites in balloon-type bubble bioreactors (BTBBs) have been optimized. The results of the culture showed that the best culture conditions were a cone angle of 90° bioreactor and 0.4-0.6-0.4-vvm aeration volume. Aspergillus niger can be used as a fungal elicitor to enhance the production of defense compounds in plants. With the addition of a fungal elicitor (derived from Aspergillus niger), the maximum accumulation of total flavonoids (16.12 mg g(-1)) and glycyrrhetinic acid (0.18 mg g(-1)) occurred at a dose of 400 mg L(-1) of Aspergillus niger resulting in a 3.47-fold and 1.8-fold increase over control roots. However, the highest concentration of polysaccharide (106.06 mg g(-1)) was achieved with a mixture of elicitors (Aspergillus niger and salicylic acid) added to the medium, resulting in a 1.09-fold increase over Aspergillus niger treatment alone. Electrospray ionization tandem mass spectrometry (ESI-MS(n)) analysis was performed, showing that seven compounds were present after treatment with the elicitors, including uralsaponin B, licorice saponin B2, liquiritin, and (3R)-vestitol, only identified in the mixed elicitor treatment group. It has also been found that elicitors (Aspergillus niger and salicylic acid) significantly upregulated the expression of the cinnamate 4-hydroxylase (C4H), β-amyrin synthase (β-AS), squalene epoxidase (SE) and a cytochrome P450 monooxygenase (CYP72A154) genes, which are involved in the biosynthesis of bioactive compounds, and increased superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) activity.

    2015-10-01

    Full Text Available This article reviews some of Tore Linné Eriksen’s works within development studies/development research. In a recent introduction to development studies from 2013, he presented development research as a cross-disciplinary social science approach that addresses the grand problems of mankind. Eriksen’s own research into these grand problems has concentrated on the causes of national and international inequality and poverty. In 1974 he supported the view of the “underdevelopment school”: “Underdevelopment” in Africa and Latin America was the outcome of the inclusion of those continents in a capitalist world economy dominated by Europe. Recent works by Eriksen on the origins of the “great divergence” between Western Europe and economically advanced non-European countries (2010 and on inequality and poverty in the current world (2012 are far more complex and empirically nuanced. Still, in a recent discussion of globalization and global capitalism (2013 he reverts to some of the earlier ”underdevelopment arguments” from 1974. The article concludes that there is a tension within Eriksen’s works on the role of capitalism in development and underdevelopment. In his programmatic writings, global capitalism is seen as the main cause of inequality and poverty. In his more empirically grounded works, global capitalism is viewed rather as an important part of the bigger picture of inequality and poverty.

    Scoparia dulcis Linn. (SD) is a perennial herb that has been well studied for its antioxidant, anti-inflammatory, antidiabetic, and hepatoprotective effects. However, scientific information on SD regarding the neuropharmacological effect is limited. This study evaluated the sedative and hypnotic effect of the ethanolic extract of whole plants of Scoparia dulcis (EESD). For this purpose, the whole plants of S. dulcis were extracted with ethanol following maceration process and tested for the presence of phytochemical constituents. The sedative and hypnotic activity were then investigated using hole cross, open field, hole-board, rota-rod, and thiopental sodium-induced sleeping time determination tests in mice at the doses of 50, 100, and 200 mg/kg of EESD. Diazepam at the dose of 1 mg/kg was used as a reference drug in all the experiments. We found that EESD produced a significant dose-dependent inhibition of locomotor activity of mice both in hole cross and open field tests (P < 0.05). Besides, it also decreased rota-rod performances and the number of head dips in hole-board test. Furthermore, EESD significantly decreased the induction time to sleep and prolonged the duration of sleeping, induced by thiopental sodium. Taken together, our study suggests that EESD may possess sedative principles with potent hypnotic properties.

It is a major Medhya Rasayana used in Ayurveda for treatment of memory disorders. Large number of saponins and glycosides has been isolated from the plant. Most of the experimental and clinical studies have been done with crude extracts or standardized preparation of the two active saponins Bacosides A and B.Extracts or saponin mixture facilitate learning, improve consolidation of learned behavior and delay extinction in several models of learnt behavior in normal rats and mice as well as in chemically induced or transgenic models of Alzheimer's disease. They also prevent or reverse amnesia produced by drugs, stress or ischemic hypoxia. Other CNS effects include anti-anxiety, anti-convulsant and analgesic activity. Several mechanisms have been proposed to explain the mechanism of these CNS effects.Extracts as well as the bacoside preparation have been found safe and well tolerated in healthy volunteers in single dose or chronic administration for several weeks in a number of double blind placebo controlled studies in India and abroad. Chronic administration significantly improved information processing, learning and memory consolidation. It was found more effective than caffeine in a comparative study.Double blind placebo controlled studies with bacoside preparation have demonstrated beneficial effects and safety in elderly patients with Age Related Memory Impairment and in children with Attention Deficit Memory Disorder. It has also been found useful in anxiety neurosis, epilepsy and sleep disturbances in post menopausal women.The standardized preparation is marketed as a prescription drug after having obtained the necessary regulatory approval in India, Australia, New Zealand and South Africa and as an OTC product in several other south east Asian and African countries.Bacopa monniera Linn

    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.

    Detection of drug-drug interactions is essential during the early stages of drug discovery and development, and the understanding of drug-botanical interactions is important for the safe use of botanical dietary supplements. Among the different forms of drug interactions that are known, inhibition of cytochrome P450 (P450) enzymes is the most common cause of drug-drug or drug-botanical interactions. Therefore, a rapid and comprehensive mass spectrometry-based in vitro high-throughput P450 cocktail inhibition assay was developed that uses 10 substrates simultaneously against nine CYP isoforms. Including probe substrates for CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and two probes targeting different binding sites of CYP3A4/5, this cocktail simultaneously assesses at least as many P450 enzymes as previous assays while remaining among the fastest due to short incubation times and rapid analysis using ultrahigh pressure liquid chromatography-tandem mass spectrometry. The method was validated using known inhibitors of each P450 enzyme and then shown to be useful not only for single-compound testing but also for the evaluation of potential drug-botanical interactions using the botanical dietary supplement licorice (Glycyrrhiza glabra) as an example.

    Jayasundar, Rama; Ghatak, Somenath

    The use of medicinal plants in Ayurveda is based on rasa, generally taken to represent taste as a sensory perception. This chemosensory parameter plays an important role in Ayurvedic pharmacology. The aim is to explore the use of structuro-functional information deduced from analytical techniques for the rasa-based classification of medicinal plants in Ayurveda. Methods of differential sensing and spectroscopic metabolomics have been used in select medicinal plants from three different taste categories (sweet, pungent and multiple taste): Tribulus terrestris, Vitis vinifera and Glycyrrhiza glabra from sweet category; Piper longum, Cuminum cyminum and Capsicum annum from pungent group; Emblica officinalis with five tastes. While Electronic tongue was used for evaluation of the sensorial property of taste, the chemical properties were studied with Nuclear Magnetic Resonance (NMR), Fourier Transform InfraRed (FTIR) and Laser Induced Breakdown Spectroscopy (LIBS). In terms of taste and phytochemical profiles, all samples were unique but with similarities within each group. While the sensor response in E-tongue showed similarities within the sweet and pungent categories, NMR spectra in the aromatic region showed close similarities between the plants in the sweet category. The sensory, phytochemical and phytoelemental profiles of E. officinalis (with five rasa) in particular, were unique. A combination of sensorial and chemical descriptors is a promising approach for a comprehensive evaluation and fingerprinting of the Ayurvedic pharmacological parameter rasa.

    2017-01-01

    Breast cancer has continued to cause high cancer death rates among women worldwide. The use of plants' natural products in breast cancer treatment has received more attention in recent years due to their potentially wider safety margin and the potential to complement conventional chemotherapeutic drugs. Plantbased products have demonstrated anticancer potential through different biological pathways including modulation of the immune system. Immunomodulatory properties of medicinal plants have been shown to mitigate breast cancer cell growth. Different immune cell types participate in this process especially cytotoxic T cells and natural killer cells, and cytokines including chemokines and tumor necrosis factor-α. Medicinal plants such as Glycyrrhiza glabra, Uncaria tomentosa, Camellia sinensis, Panax ginseng, Prunus armenaica (apricot), Allium sativum, Arctium lappa and Curcuma longa were reported to hold strong potential in breast cancer treatment in various parts of the world. Interestingly, research findings have shown that these plants possess bioactive immunomodulators as their main constituents producing the anticancer effects. These immunomodulatory compounds include ajoene, arctigenin, β-carotene, curcumin, epigallocatechin-3-gallate, ginsan, glabridin and quinic acid. In this review, we discussed the ability of these eight immunomodulators in regulating the immune system potentially applicable in breast cancer treatment via anti-inflammatory (curcumin, arctigenin, glabridin and ajoene) and lymphocytes activation (β-carotene, epigallocatechin-3-gallate, quinic acid and ginsan) properties, as well as future research direction in their use for breast cancer treatment.

    Here we used Illumina RNA-seq technology for transcriptome sequencing of a mixed fruit sample from 'Zill' mango (Mangifera indica Linn) fruit pericarp and pulp during the development and ripening stages. RNA-seq generated 68,419,722 sequence reads that were assembled into 54,207 transcripts with a mean length of 858bp, including 26,413 clusters and 27,794 singletons. A total of 42,515(78.43%) transcripts were annotated using public protein databases, with a cut-off E-value above 10(-5), of which 35,198 and 14,619 transcripts were assigned to gene ontology terms and clusters of orthologous groups respectively. Functional annotation against the Kyoto Encyclopedia of Genes and Genomes database identified 23,741(43.79%) transcripts which were mapped to 128 pathways. These pathways revealed many previously unknown transcripts. We also applied mass spectrometry-based transcriptome data to characterize the proteome of ripe fruit. LC-MS/MS analysis of the mango fruit proteome was using tandem mass spectrometry (MS/MS) in an LTQ Orbitrap Velos (Thermo) coupled online to the HPLC. This approach enabled the identification of 7536 peptides that matched 2754 proteins. Our study provides a comprehensive sequence for a systemic view of transcriptome during mango fruit development and the most comprehensive fruit proteome to date, which are useful for further genomics research and proteomic studies. Our study provides a comprehensive sequence for a systemic view of both the transcriptome and proteome of mango fruit, and a valuable reference for further research on gene expression and protein identification.

    We report an eco-friendly method for the synthesis of copper nanoparticles (CuNPs) using Citron juice (Citrus medica Linn.), which is nontoxic and cheap. The biogenic copper nanoparticles were characterized by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 631 nm which is specific for CuNPs. Nanoparticles tracking analysis by NanoSight-LM20 showed the particles in the range of 10-60 nm with the concentration of 2.18 × 10(8) particles per ml. X-ray diffraction revealed the FCC nature of nanoparticles with an average size of 20 nm. The antimicrobial activity of CuNPs was determined by Kirby-Bauer disk diffusion method against some selected species of bacteria and plant pathogenic fungi. It was reported that the synthesized CuNPs demonstrated a significant inhibitory activity against Escherichia coli followed by Klebsiella pneumoniae, Pseudomonas aeruginosa, Propionibacterium acnes and Salmonella typhi. Among the plant pathogenic fungi tested, Fusarium culmorum was found to be most sensitive followed by F. oxysporum and F. graminearum. The novelty of this work is that for the first time citron juice was used for the synthesis of CuNPs.

    1991-01-01

    An investigation of the hydrogeology and groundwater quality conditions near the Linn County Landfill, eastern Kansas was conducted from July 1988 through June 1989. The landfill is located in an unreclaimed coal strip-mine area near Prescott. Analysis of water levels from nine temporary wells and from strip-mine ponds indicated that groundwater flows southwest through the present landfill. A county road west of the landfill acts as a barrier to shallow westerly groundwater flow. Seasonal variations in the direction of groundwater flow may occur. Water samples from monitoring wells and a strip-mine pond were analyzed for inorganic and organic compounds. Iron, manganese, and dissolved-organic-carbon concentrations were good indicators of the presence of landfill leachate in the groundwater. Benzene, carbon tetrachloride, 1,1-dichloroethane, and 1,1,1-trichloroethane were also detected. None of the inorganic or organic compounds detected exceeded Kansas primary drinking-water standards. Chemical concentrations and water levels in some nested wells indicate there is a hydraulic connection between the strip-mine spoil material and the underlying limestone. Leachate-contaminated groundwater has the potential to migrate southwest corner of the landfill through either strip-mine spoil material or through the underlying Pawnee Limestone

    Piper betle Linn. is a Pan-Asiatic plant having several beneficial properties. Protein glycation and advanced glycation end products (AGEs) formation are associated with different pathophysiological conditions, including diabetes mellitus. Our study aims to find the effect of methanolic extract of P. betle leaves on in vitro protein glycation in bovine serum albumin (BSA)-glucose model. The extract inhibits glucose-induced glycation, thiol group modification and carbonyl formation in BSA in dose-dependent manner. It inhibits different stages of protein glycation, as demonstrated by using glycation models: hemoglobin-delta-gluconolactone (for early stage, Amadori product formation), BSA-methylglyoxal (for middle stage, formation of oxidative cleavage products) and BSA-glucose (for last stage, formation of AGEs) systems. Several phenolic compounds are isolated from the extract. Considering their relative amounts present in the extract, rutin appears to be the most active antiglycating agent. The extract of P. betle leaf may thus have beneficial effect in preventing protein glycation and associated complications in pathological conditions.

OS is commonly known as “holy basil” and “Tulsi” and is used in the Indian System of Medicine as antidiabetic, antioxidant, hepatoprotective, adaptogenic, and cardioprotective. Monocrotaline (MCT) administration caused development of PH in rats after 28 days and rats were observed for 42 days. Treatments (sildenafil; 175 µg/kg, OS; 200 mg/kg) were started from day 29 after the development of PH and continued for 14 days. Parameters to assess the disease development and effectiveness of interventions were echocardiography, right and left ventricular systolic pressures, and right ventricular end diastolic pressure, percentage medial wall thickness (%MWT) of pulmonary artery, oxidative stress markers in lung tissue, NADPH oxidase (Nox-1) protein expression in lung, and mRNA expression of Bcl2 and Bax in right ventricular tissue. OS (200 mg/kg) treatment ameliorated increased lung weight to body weight ratio, right ventricular hypertrophy, increased RVSP, and RVoTD/AoD ratio. Moreover, OS treatment decreases Nox-1 expression and increases expression of Bcl2/Bax ratio caused by MCT. The present study demonstrates that OS has therapeutic ability against MCT-induced PH in rat which are attributed to its antioxidant effect. The effect of OS was comparable with sildenafil.

    The Jatropha curcas L. (Euphorbiaceae) herb is found in SouthWest, Nigeria and other parts of West Africa, and is claimed to possess anti-hypertensive property. The phytochemical screening and flavonoid quantification of the leaf extract of Jatropha curcas Linn were studied. The phytochemical screening of the methanolic leaf extract of J. curcas L. was carried using acceptable and standard methods. The flavonoid contents of the leaf extract of Jatropha curcas L. were determined using thin layer chromatography (TLC), infrared spectroscopy (IRS) and a reversed phase high performance liquid chromatography (HPLC). The phytochemical screening of the methanolic extract of the leaves of the plant shows the presence of alkaloids, cardiac glycosides, cyanogenic glycosides, phlobatannins, tannins, flavonoids and saponins. To quantify the flavonoid contents of leaf extract of Jatropha curcas L, extracts from the plant samples where examined in a C-18 column with UV detection and isocratic elution with acetonitrile; water (45:55). Levels of flavonoids (flavones) in leaves ranged from 6:90 to 8:85 mg/g dry weight. Results indicate that the methanolic extract of the leaves of Jatropha curcas L. contains useful active ingredients which may serve as potential drug for the treatment of diseases. In addition, a combination of TLC, IRS and HPLC can be used to analyse and quantify the flavonoids present in the leaves of Jatropha curcas L.

    An efficient simplified method was developed to determine multiple classes of phytohormones simultaneously in the medicinal plant Glycyrrhiza uralensis. Ultrahigh-performance liquid chromatography electrospray ionization tandem mass spectrometry (UPLC/ESI-MS/MS) with multiple reaction monitoring (MRM) in negative mode was used for quantification. The five studied phytohormones are gibberellic acid (GA3), abscisic acid (ABA), jasmonic acid (JA), indole-3-acetic acid, and salicylic acid (SA). Only 100 mg of fresh leaves was needed, with one purification step based on C18 solid-phase extraction. Cinnamic acid was chosen as the internal standard instead of isotope-labeled internal standards. Under the optimized conditions, the five phytohormones with internal standard were separated within 4 min, with good linearities and high sensitivity. The validated method was applied to monitor the spatial and temporal changes of the five phytohormones in G. uralensis under ABA stress. The levels of GA3, ABA, JA, and SA in leaves of G. uralensis were increased at different times and with different tendencies in the reported stress mode. These changes in phytohormone levels are discussed in the context of a possible feedback regulation mechanism. Understanding this mechanism will provide a good chance of revealing the mutual interplay between different biosynthetic routes, which could further help elucidate the mechanisms of effective composition accumulation in medicinal plants.

    Mucilage isolated from seeds of Manilkara zapota (Linn.) P. Royen syn. is a plant growing naturally in the forests of India. This mucilage is yet to be commercially exploited, and characterized as polymer. Various physicochemical methods like particle size analysis, scanning electron microscopy, thermal analysis, gel permeation chromatography, X-ray diffraction spectrometry, zeta potential, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy have been employed to characterize this gum in the present study. Particle size analyses suggest that mucilage has particle size in nanometer. Scanning electron microscopy analysis suggests that the mucilage has irregular particle size. The glass transition temperature of the gum was observed to be 138°C and 136°C by differential scanning calorimetry and differential thermal analysis, respectively. The thermogravimetric analysis suggested that mucilage had good thermal stability. The average molecular weight of mucilage was determined to be 379180, by gel permeation chromatography, while the viscosity of mucilage was observed to be 219.1 cP. The X-ray diffraction spectrometry pattern of the mucilage indicates a completely amorphous structure. Elemental analysis of the gum revealed the contents of carbon, hydrogen, nitrogen, and sulfur to be 80.9 (%), 10.1 (%), 1.58 (%), and 512 (mg/kg), respectively. Mucilage had specific content of calcium, magnesium, potassium, lower concentrations of aluminum, cadmium, cobalt, lead, and nickel. The major functional groups identified from FT-IR spectrum include 3441 cm(-1) (-OH), 1660 cm(-1) (Alkenyl C-H & C=C Stretch), 1632 cm(-1) (-COO-), 1414 cm(-1) (-COO-), and 1219 cm(-1) (-CH3CO). Analysis of mucilage by paper chromatography and 1D NMR, indicated the presence of rhamnose, xylose, arabinose, mannose, and fructose.

    Anacardium occidentale Linn (cajueiro) and Anadenanthera colubrina (Vell.) Brenan (angico) are very know as a source of phenolic compounds, mainly tannins. The aim of this study was to evaluate the difference of phenols and tannins contents of crude extracts were measured after irradiation of barks and leaves of each plant source, using a source of {sup 60}Co. The crude extracts were divided into control group and three groups which were separately after exposition to gamma radiation, in doses of 5; 7.5 and 10 kGy. From each group, the total phenols were quantified by the Folin-Ciocalteau method, while the contents of tannins were assessed using precipitation of the casein technique. For all doses, the total phenol and tannin percentages from 'cajueiro' barks presented no significant statistical alteration. However, for the leaves of 'cajueiro', their chemical composite levels significantly changed with the radiation absorbed dose. On the other hand, the gamma irradiation did not cause alterations in total phenols and tannins content of extracts from 'angico'. (author)

    Full Text Available Enrichment planting in naturally recovering secondary forests or in tree plantations is increasingly being used as strategy to restore later-successional, large-seeded tropical forest trees. We seeded two tree species (Otoba novogranatensis and Ruagea glabra in three agricultural sites in Southern Costa Rica: abandoned pastures, eight to ten year old secondary forests and three year old tree plantations (containing two N-fixing of four total tree species. We measured micrometeorological conditions, soil water content, plant water potential, leaf area, foliar C and N, and photosynthesis to better understand mechanistic responses of seedlings to conditions in the different successional habitats. Micrometeorological conditions, soil water content, and plant water potential were generally similar across habitats. Certain aspects of leaves (such as Specific Leaf Area and foliar N content, and photosynthesis (e.g. quantum yield and electron transport rate were highest in the plantations, intermediate in the secondary forests, and lowest in abandoned pastures. Enhanced rates of photosynthetic biochemistry (such as Vcmax and Jmax and Photosystem II efficiency (e.g. thermal energy dissipation occurred in leaves from the plantations compared to the abandoned pastures, which may be related to higher leaf %N content. Results suggest that foliar N may be of greater importance than soil water content and micrometeorological factors in driving differences in photosynthetic processes across planting habitats. Planting seeds of these two species in plantations containing three year old trees (including two N-fixing species enhances certain aspects of their photosynthesis and growth, compared to seedlings in abandoned pastures with non-native grasses, and thus can help increase forest recovery on abandoned agricultural lands.

    Effect of heat treatment on yield and some quality parameters of loofah seed (Luffa cylindrical Linn.) oil was the focus of this study. Central composite rotatable response surface methodology design for two variables was used for this investigation. Fatty acid composition of the un-treated oil was determined. The independent variables roasting temperature were 102, 110, 130, 150, 158 degree C and duration 16, 20, 30, 40, 44 min while oil yield, moisture content, free fatty acid, colour, refractive index and specific gravity of the oil were the dependent variables. All determinations were done using standard methods. Linoleic acid (50.66%), oleic acid (27.66%), palmitic acid (12.28%) and stearic acid (6.44%) were the major fatty acids. Mean oil yield, moisture, free fatty acid, colour, refractive index and specific gravity were 25.9 ± 5.16%, 0.035 ± 0.003%, 5.3 ± 2.47%, 15.23 ± 1.83 mg/100g, 1.47 ± 0.002 ND 40 and 0.913 ± 0.02, respectively. All the parameters were significantly affected by heat treatment (p<0.05). Regression models were not fit to express the relation, thus optimisation using response surface approach was not adequate.

    Full Text Available This work has been done for the investigation of the anti-inflammatory and analgesic activity of methanol extract of dried leaves of Murraya koenigii Linn by oral administration at dose of 100, 200 and 400 mg/kg body weight, to healthy animals. Extract was studied for its anti-inflammatory activity by using carrageenan-induced hind paw edema in albino rats and the mean increase in paw volume and % inhibition in paw volume were measured plethysmometrically at different time intervals after carrageenan (1% w/v injection. Extract was also evaluated for analgesic activity using Eddy′s hot plate method and formalin induced paw licking method in albino rats. The methanol extract showed significant (P < 0.001 reduction in the carrageenan-induced paw edema and analgesic activity evidenced by increase in the reaction time by eddy′s hot plate method and percentage increase in pain in formalin test. The methanol extract showed anti-inflammatory and analgesic effect in dose dependent manner when compared with the control and standard drug, diclofenac sodium (10mg/kg, p.o. These inhibitions were statistically significant (P < 0.05. Thus our investigation suggests a potential benefit of Murraya koenigii in treating conditions associated with inflammatory pain.

    The nephroprotective activity of the ethanolic extract of Bauhinia variegata (Linn.) whole stem against cisplatin-induced nephropathy was investigated by an in vivo method in rats. Acute nephrotoxicity was induced by i.p. injection of cisplatin (7 mg/kg of body weight (b.w.)). Administration of ethanol extract at dose levels of 400 and 200 mg/kg (b.w.) to cisplatin-intoxicated rats for 14 days attenuated the biochemical and histological signs of nephrotoxicity of cisplatin in a dose-dependent fashion. Ethanol extract at 400 mg/kg decreased the serum level of creatinine (0.65 ± 0.09; P<0.001) and urea (32.86 ± 5.88; P<0.001) associated with a significant increase in body weight (7.16 ± 1.10; P<0.001) and urine volume output (11.95 ± 0.79; P<0.05) as compared to the toxic control group. The ethanol extract of B. variegata at 400 mg/kg (b.w.) exhibited significant and comparable nephroprotective potential to that of the standard polyherbal drug cystone. The statistically (one-way-ANOVA followed by Tukey-Kramer multiple comparison) processed results suggested the protective action of B. variegate whole stem against cisplatin-induced nephropathy.

    Arundo donax linn, as a perennial energy crop, has promising application prospect. In the present study, Fourier transform Raman (FT Raman) spectroscopy was applied to determine the structural information of materials, milled wood lignin (MWL), and alkaline lignins (AL, under different treated time) from A. donax stem nondestructively. The results indicated that, extractable compounds in A. donax had negative contribution to the Raman spectra without rising new Raman peaks. FT Raman spectrum of MWL indicated that MWL from A. donax was HGS type lignins. Compared with the spectra of MWL from wood materials, the peak at 1173 cm(-1) was much higher in intensity for the MWL from A. donax stem, which may be assigned to hydroxycinnamic acid by analyzing the standard. With respect to FT Raman spectra of ALs, the relatively highest intensity of 1173 cm(-1) was found in alkaline lignin (AL2), which was treated for 40 min by alkaline. Moreover, the peak of coniferaldehyde/sinapaldehyde (1630 cm(-1)) was lowest in intensity while the band attributed to coniferyl alcohol/sinapyl alcohol (1660 cm(-1)) was almost disappeared in AL2. It could be inferred that AL2 demonstrated a highest content of phenolic acid, which may improve its potential application, such as for antioxidant activity. Furthermore, the results obtained by FT Raman spectra were verified by two dimensional heteronuclear singlequantum coherence nuclear magnetic resonance analyses. Above all, FT Raman spectroscopy provided alternative safe, rapid, accurate, and nondestructive technology for lignin structure determination.

    Grewia asiatica Linn. (Family: Tiliaceae), called Phalsa in Hindi is an Indian medicinal plant used for a variety of therapeutic and nutritional uses. The root bark of the plant is traditionally used in rheumatism (painful chronic inflammatory condition). The present study demonstrates the analgesic and anti-inflammatory activity of root bark of G. asiatica in rodents. The methanolic extract of Grewia asiatica (MEGA) and aqueous extract of Grewia asiatica (AEGA) of the bark were prepared and subjected to phytochemical tests and pharmacological screening for analgesic and anti-inflammatory effect in rodents. Analgesic effect was studied using acetic acid-induced writhing in mice and hot plate analgesia in rats while anti-inflammatory activity was investigated using carrageenan-induced paw oedema in rats. The MEGA or AEGA was administered orally in doses of 200 and 400 mg/kg/day of body weight. Data were analysed by one-way analysis of variance followed by Dunnett's test. The extracts showed a significant inhibition of writhing response and increase in hot plate reaction time and also caused a decrease in paw oedema. The effects were comparable with the standard drugs used. The present study indicates that root bark of G. asiatica exhibits peripheral and central analgesic effect and anti-inflammatory activity, which may be attributed to the various phytochemicals present in root bark of G. asiatica.

    Full Text Available Objective: Ankaferd hemostat is the first topical hemostatic agent about the red blood cell–fibrinogen relations tested in the clinical trials. Ankaferd hemostat consists of standardized plant extracts including Alpinia officinarum, Glycyrrhiza glabra, Thymus vulgaris, Urtica dioica, and Vitis vinifera. The aim of this study was to determine the effect of Ankaferd hemostat on viability of melanoma cell lines. Methods: Dissimilar melanoma cell lines and primary cells were used in this study. These cells were treated with different concentrations of Ankaferd hemostat to assess the impact of different dosages of the drug. All cells treated with different concentrations were incubated for different time intervals. After the data had been obtained, one-tailed T-test was used to determine whether the Ankaferd hemostat would have any significant inhibitory impact on cell growth. Results: We demonstrated in this study that cells treated with Ankaferd hemostat showed a significant decrease in cell viability compared to control groups. The cells showed different resistances against Ankaferd hemostat which depended on the dosage applied and the time treated cells had been incubated. We also demonstrated an inverse relationship between the concentration of the drug and the incubation time on one hand and the viability of the cells on the other hand, that is, increasing the concentration of the drug and the incubation time had a negative impact on cell viability. Conclusion: The findings in our study contribute to our knowledge about the anticancer impact of Ankaferd hemostat on different melanoma cells.

    To search major Traditional Persian Medicine (TPM) textbooks for medicinal plants used to treat asthma. The conformity of the TPM findings on the anti-asthmatic efficacy of plants with the findings of pharmacological studies was also explored. Major TPM textbooks were hand searched to find medicinal plants used for the treatment of asthma. Scientific names of TPM-suggested plants were determined using botanical databases and were used for a multidatabase electronic search in PubMed, Scopus, ScienceDirect and Google Scholar databases. Then, the antiasthmatic effectiveness of TPM-recommended plants was verified in view of the findings from modern pharmacological investigations. According to the main TPM texts, Adianthum capillus-veneris, Boswellia oleogumresin, Crocus sativus, Glycyrrhiza glabra, Hyssopus officinalis and Ruta graveolens were the most efficacious medicinal plants for the treatment of asthma. This finding was confirmed by pharmacological studies which showed counterbalancing effects of the above-mentioned plants on inflammation, oxidative stress, allergic response, tracheal smooth muscle cell constriction and airway remodeling. The strong ethnobotanical background of plants used in TPM could be a valuable tool to find new anti-asthmatic medications. In this review, TPM-suggested anti-asthmatic plants were found to possess several mechanisms relevant to the treatment of respiratory diseases according to the information retrieved from modern pharmacological studies. This high degree of conformity suggested further proof-of-concept trials to ascertain the role of these plants in the routine management of asthmatic patients.

    2013-01-01

    Herbal therapies gained much popularity among the general public, but compared to therapies approved by official authorities, toxicological studies are frequently not available for them. Hence, there may be inherent risks and the kidneys may be especially vulnerable to toxic effects. Herbs may induce nephrotoxicity by induction of apoptosis. High oxalate contents in Star fruit (Averrhoa carambola L.) may induce acute nephropathy. Triptolide from Thunder God Vine (Triperygium wilfordii Hook) is a diterpenoid epoxide with induces reactive oxygen species and nephrotubular apoptosis. Cranberry juice is discussed as promoter of kidney stone formation (nephrolithiasis). Abuse of guaifenesin from Roughbark (Guaicum officinale L.) increases stone formation. Aristolochia acids from Aristolochia fangchi Y.C.Wu ex L.D. Chow & S.M. Hwang causes the well-known aristolochic acid nephropathy and carcinogenesis by DNA adduct formation. Carboxyatractyloside from Impila (Callilepsis laureola DC.) inhibits mitochondrial ATP synthesis. Acute allergic interstitial nephritis was diagnosed after intake of Peruvian Cat's claw (Uncaria tomentosa Willd. DC.). Whether or not Willow Bark (Salix alba L.) induces analgesic nephropathwy is a matter of discussion. Other herbal therapies are considered to affect the rennin-angiotensisn-aldosterone (RAA) system Ephedra sinica Stapf with its ingredient ephedrine. Devil's Claw (Harpagophytum procumbens DC. Ex Meisn.) and licorice (Glycyrrhiza glabra L.) may inhibit major renal transport processes needed for filtration, secretion, and absorption. Strategies to minimize nephrotoxicity include (1) quality control and standardization of herbal products, (2) research on the molecular modes of action to better understand pathophysiological mechanisms of herbal products as well as (3) clinical trials to demonstrate efficacy and safety.

    Full Text Available Abstract Background Obesity is recognized as a social problem, associated with serious health risks and increased mortality. Numerous trials have been conducted to find and develop new anti-obesity drugs through herbal sources to minimize side effects associated with the present anti-obesity drugs. The present study was designed to evaluate the quality control parameters, quantitative phytochemical analysis (total phenolic, total flavonoids and total saponin content, and the anti-obesity effect of lyophilized juice (LJ of Stellaria media (Linn. Vill. by employing in vitro and in vivo models. Methods In vitro studies were performed to evaluate the inhibitory activity of LJ on pancreatic amylase and lipase. The in vivo pancreatic lipase activity was evaluated by measurement of plasma triacylglycerol levels after oral administration of lipid emulsion to swiss albino mice. Furthermore, the anti-obesity effect of LJ was assessed at two doses, 400 mg/kg and 900 mg/kg body weight in mice fed a high-fat-diet with or without LJ for 6 weeks. Results The LJ inhibited pancreatic amylase and lipase activity in vitro and elevated plasma triacylglycerol level in mice. LJ suppressed the increase in body weight, retroperitoneal adipose tissue, liver weights and serum parameters viz., total cholesterol, total triglyceride, LDL-cholesterol level at the dose of 900 mg/kg body weight of the mice fed with high fat diet. The total phenolic, flavonoid and saponin contents were found to be 0.26 mg/g, 1.4 mg/g and 1.19 μg/g respectively of LJ. Conclusion The anti-obesity effects of LJ in high-fat-diet fed mice may be partly mediated through delaying the intestinal absorption of dietary fat and carbohydrate by inhibiting digestive enzymes.

    Nicotiana plumbignifolia (Linn) is used as folk medicine in the treatment of liver dysfunction in Pakistan. The present study was designed to investigate the hepatoprotective role of N. plumbignifolia methanolice extract (NPME) against carbon tetrachloride (CCl4)-induced oxidative damage in liver of chicks. Methanolic extract of N. plumbignifolia was obtained and was further evaluated as a hepatoprotective agent against CCl4-induced oxidative damage in liver of chicks. For this study, 60-day-old 50 male chicks were divided into five groups. Chicks of group 1 (control) had free access to food and water. Group II received 1 mL/kg of CCl4 (30% in olive oil v/v) via the intraperitoneal route thrice a week for 4 weeks. Group III received 100 mg/kg body weight (b.w.) of silymarin via gavage after 48 h of CCl4 treatment, whereas group IV were given 200 mg/kg b.w. NPME after 48 h of CCl4 treatment. Hepatoprotective activity was assessed by measuring the activities of the antioxidant enzymes: catalase, peroxidase, superoxide dismutase, glutathione peroxidase, glutathione reductase, and lipid peroxidation (thiobarbituric acid reactive substances (TBARS)). Serum was analyzed for various biochemical parameters. The results revealed that CCl4 induced oxidative stress as evidenced by the significant decrease in the activity levels of antioxidant enzymes, while an increase in the levels of TBARS in liver samples is compared with the control group. Serum levels lactate dehydrogenase, triglycerides, total cholesterol, and low-density lipoprotein was elevated while reducing high-density lipoprotein compared to controls. Cotreatment of NPME treatment reversed these alterations, which seems likely that NPME can protect the liver tissues against CCl4-mediated oxidative damage. © The Author(s) 2013.

    Oregon state law requires each county in the state to identify agricultural land and enact policies and regulations to protect agricultural land use. State guidelines encourage the preservation of large parcels of agricultural land and discourage partitioning of agricultural land and construction of nonfarm dwellings in agricultural areas. A land evaluation and site assessment (LESA) system was developed in Linn County to aid in the identification of agricultural land and provide assistance to decision makers concerning the relative merits of requests to partition existing parcels of ricultural land and introduce nonagricultural uses. Land evaluation was determined by calculating soil potential ratings for each agricultural soil in the county based on the soil potentials for winter wheat, annual ryegrass, permanent pasture, and irrigated sweet corn. Soil potential ratings were expressed on a scale of 0 to 150 points. The land evaluation score for a parcel consists of the weighted average soil potential rating for all of the soils in the parcel, weighted by the percentage of each soil present in the parcel. Site assessment was based on the size of a parcel and on the amount of existing conflict between agricultural and nonagricultural uses, particularly rural residential uses, both adjacent to and in the vicinity of a parcel. Parcel size refers to both size in relation to a typical field and size in relation to a typical farm unit. Conflict takes into account the number of nonfarm dwellings within 1/4 mile (0.4 km) of a parcel, the amount of the perimeter that adjoins conflicting land uses, and the residential density adjacent to the parcel. Empirical scales were derived for assigning points to each of the site assessment factors. Both parcel size and conflict were worth 75 points in the model. For parcel size, 45 points were allocated to field size and 30 points to farm-unit size. For conflict, 30 points were allocated to nonfarm dwellings within 1/4 mile and 45

    The antimicrobial activity of phenolic compounds from Olea (O.) europaea Linné (L.) is part of the scientific discussion regarding the use of natural plant extracts as alternative food preservative agents. Although, the basic knowledge on the antimicrobial potential of certain molecules such as oleuropein, hydroxytyrosol or elenolic acid derivatives is given, there is still little information regarding their applicability for food preservation. This might be primarily due to the lack of information regarding the full antimicrobial spectrum of the compounds, their synergisms in natural or artificial combinations and their interaction with food ingredients. The present review accumulates available literature from the past 40 years, investigating the antimicrobial activity of O. europaea L. derived extracts and compounds in vitro and in food matrices, in order to evaluate their food applicability. In summary, defined extracts from olive fruit or leaves, containing the strongest antimicrobial compounds hydroxytyrosol, oleacein or oleacanthal in considerable concentrations, appear to be suitable for food preservation. Nonetheless there is still need for consequent research on the compounds activity in food matrices, their effect on the natural microbiota of certain foods and their influence on the sensorial properties of the targeted products.

    Adiantum capillus-veneris Linn (Maidenhair fern) is an herb belonging to the family Pteridaceae. It is named as " Pare-siavashan " in medical and pharmaceutical textbooks of Iranian Traditional Medicine. The fronds of Maidenhair fern were mainly administrated by ancient physicians as single medicine or in combination with other plants in multi-herbal formulations for curing different diseases. Because of different chemical compositions, the herb fronds were also assessed for its numerous pharmacological effects. Therefore, the current study was done to review the traditional usage and modern pharmacological and toxicological effects of Maidenhair fern. Scientific databases and publications including Web of Science, PubMed, Scopus, Science direct, Cochrane Library, SID (for Persian papers) and medical and pharmaceutical textbooks of traditional medicine as well were searched for " Adiantum capillus-veneris ", " Maidenhair fern " and " Pare-siavashan " without limitation up to 2016. Maidenhair fern exhibited to possess anti-diabetic, anticonvulsant, analgesic, hypocholesterolemic, goitrogenic, anti-thyroidal, antibacterial, antifungal, wound healing, antiobesity, anti hair loss, anti-asthmatic, anti-inflammatory, antidiarrheal and antispasmodic, antioxidant as well as diuretic, anti-urolithiatic and detoxifying effects in modern medicine. Ancient physicians declared some of the confirmed pharmacological effects. Maidenhair fern frond can be a good candidate for clinical purpose. Therefore, future researches on the other mentioned effects in traditional medicine are recommended.

    Glycyrrhizae radix has been popularly used as one of the oldest and most frequently employed botanicals in herbal medicine in Asian countries, and currently occupies an important place in food products. Cadmium (Cd) induces both apoptotic and non-apoptotic cell death, in which alterations in cellular sulfhydryls participate. In the present study, we determined the effects of G. radix extract (GRE) and its representative active components on cell death induced by Cd and explored the mechanistic basis of cytoprotective effects of G. radix. Incubation of H4IIE cells with GRE inhibited cell death induced by 10 μM Cd. Also, GRE effectively blocked Cd (1 μM)-induced cell death potentiated by buthionine sulfoximine (BSO) without restoration of cellular GSH. GRE prevented both apoptotic and non-apoptotic cell injury induced by Cd (10 μM) or Cd (0.3-1 μM) + BSO. Inhibition of Cd-induced cell injury by pretreatment of cells with GRE suggested that the cytoprotective effect result from alterations in the levels of the protein(s) responsible for cell viability. GRE inhibited mitochondrial Bad translocation by Cd or Cd+BSO, and caused restoration of mitochondrial Bcl xL and cytochrome c levels. Cd-induced poly(ADP-ribose)polymerase cleavage in control cells or in cells deprived of sulfhydryls was prevented by GRE treatment. Among the major components present in GRE, liquiritigenin, but not liquiritin, isoliquiritigenin or glycyrrhizin, exerted cytoprotective effect. These results demonstrated that GRE blocked Cd-induced cell death by inhibiting the apoptotic processes involving translocation of Bad into mitochondria, decreases in mitochondrial Bcl xL and cytochrome c, and poly(ADP-ribose)polymerase cleavage

(N. lotus with the aim of obtaining a new lead for formulating safe, inexpensive, nontoxic and readily available trypanocidal drugs. Methods: Seventy percent (v/v (methanol/water crude extract of N. lotus was evaluated for antitrypanosomal activity in experimental trypanosomiasis using Trypanosoma brucei bruceiinfected mice. Infected mice in different groups were administered intraperitoneally 100, 200, 300 and 400 mg/kg body weight/day of the crude for two weeks, while a positive control group was treated with standard drug, berenil. Results: The crude extract at a dose of 100 mg/kg body weight/day was more effective than the higher doses in completely clearing parasites from the blood of mice infected with Trypanosoma brucei brucei. Pre-treatment of healthy mice with the crude extract for 5 days before infection did not prevent the establishment of the infection, indicating that the extract had no prophylactic activity. Subinoculation of the blood and cerebrospinal fluid drawn from the cured mice into healthy mice failed to produce any infection within 50 days post inoculation. Administration of 1 000 mg/kg body weight of the crude extract led to the death of 50% of the experimental animals indicating a high level of toxicity of the extract at higher doses. Conclusions: This study has demonstrated the potency of the crude extract of N. lotus in treating experimental trypanosomiasis at lower doses.

    Although the herbal pair of Euphorbia kansui (GS) and Glycyrrhiza (GC) is one of the so-called "eighteen antagonistic medicaments" in Chinese medicinal literature, it is prescribed in a classic Traditional Chinese Medicine (TCM) formula Gansui-Banxia-Tang for cancerous ascites, suggesting that GS and GC may exhibit synergistic or antagonistic effects in different combination designs. Here, we modeled the effects of GS/GC combination with a target interaction network and clarified the associations between the network topologies involving the drug targets and the drug combination effects. Moreover, the "edge-betweenness" values, which is defined as the frequency with which edges are placed on the shortest paths between all pairs of modules in network, were calculated, and the ADRB1-PIK3CG interaction exhibited the greatest edge-betweenness value, suggesting its crucial role in connecting the other edges in the network. Because ADRB1 and PIK3CG were putative targets of GS and GC, respectively, and both had functional interactions with AVPR2 approved as known therapeutic target for ascites, we proposed that the ADRB1-PIK3CG-AVPR2 signal axis might be involved in the effects of the GS-GC combination on ascites. This proposal was further experimentally validated in a H22 hepatocellular carcinoma (HCC) ascites model. Collectively, this systems-level investigation integrated drug target prediction and network analysis to reveal the combination principles of the herbal pair of GS and GC. Experimental validation in an in vivo system provided convincing evidence that different combination designs of GS and GC might result in synergistic or antagonistic effects on HCC ascites that might be partially related to their regulation of the ADRB1-PIK3CG-AVPR2 signal axis.

    In spite of the therapeutic importance of Aristolochia bracteolata Linn. in Nigerian ethnomedicine, it is largely collected from the wild. Owing to the acclaimed potency of the plant and the difficulty in treating candidiasis, the anticandidal activity and in vitro propagation of the plant were investigated. Phytochemical screening and preparation of extracts of the roots were done using standard procedures. Clinical isolates of Candida albicans were screened against extracts and essential oil of Aristolochia bracteolata root using agar-well diffusion method. Minimum Inhibitory Concentration (MIC) of the ethanol extract was determined using broth dilution method. The nodal cuttings of A. bracteolata were cultured on Murashige and Skoog (MS) basal media. A. bracteolata contained alkaloids, saponins and cardenolides. The water extract was inactive on all isolates. The ethanol extract (500 mg/ml) and essential oil (undiluted) exhibited anticandidal activity on 9 out of 10 isolates at 10(1) - 10(6) cfu/ml inoculums concentration. Green growth and callus formation were observed in explants cultured on MS basal media after 30 days. A. bracteolata could be a source of anticandidal phytomedicine and the in vitro propagation confirmed its sustainability as anticandidal agent.

    Kenaf (Hibiscus cannabinus Linn, Pundi), Chick pea (Cicer arietinum Linn, Chana) and Prickly lettuce (Lactuca scariola Linn, Hattaraki) leaves are a few of indigenous plants which are routinely consumed by the people of north Karnataka in the diet. Studies on these plants showed some potential anti-diabetic efficacies. To examine the effect of leaves extracts of Hibiscus cannabinus Linn, Cicer arietinum Linn and Lactuca scariola Linn on cardiovascular integrity, glucose homeostasis and oxygen sensing cell signaling mechanisms in alloxan induced diabetic rats. In vitro and in vivo tests on glucose regulatory systems and molecular markers such as - NOS3, HIF- 1α and VEGF were conducted in alloxan induced diabetic rats supplemented with all the three plant extracts. Electrophysiological analysis (HRV, LF: HF ratio, baroreflex sensitivity, BRS) and histopathogy of myocardial tissues and elastic artery were evaluated in diabetic rats treated with L. scariola linn. Out of these three plant extracts, Lactuca scariola Linn supplementation showed significant beneficial effects on glucose homeostasis and oxygen sensing cell signaling pathways in alloxaninduced diabetic rats. Furthermore, effects of sub chronic supplementation of Lactuca scariola Linn aqueous extracts showed significant improvement in sympatho-vagal balance in diabetic rats by increase of Heart Rate Variability (HRV) and regaining of Baroreflex Sensitivity (BRS). These results were also corroborated with myocardial and elastic artery histopathology of Lactuca scariola Linn supplemented diabetic rats. These findings indicate an adaptive pathway for glucose homeostasis, oxygen sensing cell signaling mechanisms and cardio protective actions in alloxan - induced diabetic rats supplemented with Lactuca scariola Linn extracts.

    The influence of two varieties of betel leaf (Piper betle Linn.) namely, the pungent Mysore and non-pungent Ambadi, was examined on digestive enzymes of pancreas and intestinal mucosa and on bile secretion in experimental rats. The betel leaves were administered orally at two doses which were either comparable to human consumption level or 5 times this. The results indicated that while these betel leaves do not influence bile secretion and composition, they have a significant stimulatory influence on pancreatic lipase activity. Besides, the Ambadi variety of betel leaf has a positive stimulatory influence on intestinal digestive enzymes, especially lipase, amylase and disaccharidases. A slight lowering in the activity of these intestinal enzymes was seen when Mysore variety of betel leaf was administered, and this variety also had a negative effect on pancreatic amylase. Further, both the betel leaf varieties have shown decreasing influence on pancreatic trypsin and chymotrypsin activities.

    In a greenhouse pot experiment, dandelion (Taraxacum platypecidum Diels.) and bermudagrass (Cynodon dactylon[Linn.] Pers.), inoculated with and without arbuscular mycorrhizal fungus (AMF) Rhizophagus irregularis, were grown in chromium (Cr)-amended soils (0 mg/kg, 5 mg/kg, 10 mg/kg, and 20 mg/kg Cr[VI]) to test whether arbuscular mycorrhizal (AM) symbiosis can improve Cr tolerance in different plant species. The experimental results indicated that the dry weights of both plant species were dramatically increased by AM symbiosis. Mycorrhizal colonization increased plant P concentrations and decreased Cr concentrations and Cr translocation from roots to shoots for dandelion; in contrast, mycorrhizal colonization decreased plant Cr concentrations without improvement of P nutrition in bermudagrass. Chromium speciation analysis revealed that AM symbiosis potentially altered Cr species and bioavailability in the rhizosphere. The study confirmed the protective effects of AMF on host plants under Cr contaminations. © 2014 SETAC.

    Full Text Available One of the forms of ethnoecological tradition performed for generations by the people of the Triwidadi Village, Pajangan, DI Yogyakarta is the utilization of forest resources “duwet” (Syzygium cumini Linn as a medicinal plant. However, these values and local wisdom received less recognition and appreciation from the government, especially to be considered as a basis in the formulation of forest management policies in Java. The aims of the study are to construct local wisdom in the utilization of duwet as a form of physical culture of an institutionalized knowledge system.by using cognitive ethnographic method. This semi-quantitative research is focused to seek sociological explanation of cultural knowledge systems and duwet utilization process. Duwet habitat is in natural forest, secondary forest, and garden-yard, describes the form of changes in the environmental adaptation and social processes of forest resource utilization. The results showed that there is a symbolic interaction in the utilization of duwet consisting of constitution, cognitive, assessment and disclosure feeling symbols. In the construction of local knowledge, the utilization of duwet reflects six essential elements of ethnoecology, namely local resources, local knowledge, local value, local skills, local solidarity groups, and mechanisms of local decision-making.

    In an attempt to scientifically appraise some of the ethnomedical uses of Anacardium occidentale Linn. (family: Anacardiaceae), the present study was undertaken to examine the antiinflammatory effect of the plant's stem-bark aqueous extract in rats. Young adult male Wistar rats weighing 250-300 g were used. The antiinflammatory effect of A. occidentale stem-bark aqueous extract alone and in combination with grapefruit (Citrus paradisi Macf.) juice was investigated on fresh egg albumin-induced rat paw edema. Like diclofenac (100 mg/kg p.o.), aqueous extract of A. occidentale stem-bark (800 mg/kg p.o.) produced time-related, sustained and significant reduction (p extract was found to be approximately 8-15 times less than that of diclofenac. Coadministration of grapefruit juice (5 ml/kg p.o.) with A. occidentale stem-bark aqueous extract (800 mg/kg p.o.) or diclofenac (100 mg/kg p.o.) significantly potentiated (p extract and diclofenac on fresh egg albumin-induced rat paw edema. Although A. occidentale stem-bark aqueous extract is less potent than diclofenac as an antiinflammatory agent, the results of this experimental animal study indicate that the plant extract possesses antiinflammatory activity, and thus lend pharmacological support to the folkloric use of the plant in the management and/or control of arthritis and other inflammatory conditions among the Yoruba-speaking people of western Nigeria.

    The use of natural remedies for the treatment of liver diseases has a long history, starting with the Ayurvedhic treatment, and extending to the Chinese, European and other systems of traditional medicines. The 21st century has seen a paradigm shift towards therapeutic evaluation of herbal products in liver diseases by carefully synergizing the strengths of the traditional systems of medicine with that of the modern concept of evidence-based medicinal evaluation, standardization of herbal products and randomized placebo controlled clinical trials to support clinical efficacy. The present review provides the status report on the scientific approaches made to herbal preparations used in Indian systems of medicine for the treatment of liver diseases. In spite of the availability of more than 300 preparations for the treatment of jaundice and chronic liver diseases in Indian systems of medicine using more than 87 Indian medicinal plants, only four terrestrial plants have been scientifically elucidated while adhering to the internationally acceptable scientific protocols. In-depth studies have proved Sylibum marianum to be anti-oxidative, antilipidperoxidative, antifibrotic, anti-inflammatory, immunomodulating and liver regenerative. Glycyrrhiza glabra has been shown to be hepatoprotective and capable of inducing an indigenous interferon. Picrorhiza kurroa is proved to be anti-inflammatory, hepatoprotective and immunomodulatory. Extensive studies on Phyllanthus amarus have confirmed this plant preparation as being anti-viral against hepatitis B and C viruses, hepatoprotective and immunomodulating, as well as possessing anti-inflammatory properties. For the first time in the Indian systems of medicine, a chemo-biological fingerprinting methodology for standardization of P. amarus preparation has been patented.

    The objective of this review was to collect available data on the following: (i) adverse effects observed in humans from the intake of plant food supplements or botanical preparations; (ii) the misidentification of poisonous plants; and (iii) interactions between plant food supplements/botanicals and conventional drugs or nutrients. PubMed/MEDLINE and Embase were searched from database inception to June 2014, using the terms 'adverse effect/s', 'poisoning/s', 'plant food supplement/s', 'misidentification/s' and 'interaction/s' in combination with the relevant plant name. All papers were critically evaluated according to the World Health Organization Guidelines for causality assessment. Data were obtained for 66 plants that are common ingredients of plant food supplements; of the 492 papers selected, 402 (81.7%) dealt with adverse effects directly associated with the botanical and 89 (18.1%) concerned interactions with conventional drugs. Only one case was associated with misidentification. Adverse effects were reported for 39 of the 66 botanical substances searched. Of the total references, 86.6% were associated with 14 plants, including Glycine max/soybean (19.3%), Glycyrrhiza glabra/liquorice (12.2%), Camellia sinensis/green tea ( 8.7%) and Ginkgo biloba/gingko (8.5%). Considering the length of time examined and the number of plants included in the review, it is remarkable that: (i) the adverse effects due to botanical ingredients were relatively infrequent, if assessed for causality; and (ii) the number of severe clinical reactions was very limited, but some fatal cases have been described. Data presented in this review were assessed for quality in order to make the results maximally useful for clinicians in identifying or excluding deleterious effects of botanicals. © 2014 The British Pharmacological Society.

    In a compartmented cultivation system, white clover (Trifolium repens Linn.) and ryegrass (Lolium perenne L.), with their roots freely intermingled, or separated by 37 {mu}m nylon mesh or plastic board, were grown together in an arsenic (As) contaminated soil. The influence of AM inoculation on plant growth, As uptake, phosphorus (P) nutrition, and plant competitions were investigated. Results showed that both plant species highly depended on mycorrhizas for surviving the As contamination. Mycorrhizal inoculation substantially improved plant P nutrition, and in contrast markedly decreased root to shoot As translocation and shoot As concentrations. It also showed that mycorrhizas affected the competition between the two co-existing plant species, preferentially benefiting the clover plants in term of nutrient acquisition and biomass production. Based on the present study, the role of AM fungi in plant adaptation to As contamination, and their potential use for ecological restoration of As contaminated soils are discussed. - Both white clover and ryegrass highly depend on the mycorrhizal associations for surviving heavy arsenic contamination.

    Anacardium occidentale Linn. is popularly known as cashew plant, found in Northeastern Brazil, is of great scientific interest because it contains high levels of bioactive compounds, such as polyphenols, flavonoids and tannins, which characterize their applications as natural antioxidants, which can contribute to protect against oxidative processes in the human body. This study aimed to evaluate the effects of {sup 60}Co gamma irradiation in the antioxidant action of the extracts of leaves of A. occidentale. The extracts of A. occidentale were extracted with 70% ethanol, evaporated under reduced pressure and divided into samples control and irradiation at 10 kGy. Subsequently analyzing the kidnapping of radical DPPH (concentrations of 6.25; 12.5; 25; 50; 100 and 200 ppm) and reducing power (concentrations of 25; 50; 100; 200; 400; 600; 800 and 1000 ppm). The results showed increased antioxidant actions dependent on the concentration and dose of 10 kGy in both assays. However, the kidnapping of DPPH activity showed variations from 50% to 92% for control, and 75% and 100% for irradiated. It is observed that the irradiated samples showed maximum activity (100%) in a 4-fold lower concentration (50 ppm) than the control samples. Featuring EC{sub 50} of standards BHT (235.8%) and vitamin C (63.5%) was very low compared with control extracts (8.1%) and irradiated (0.48). However the results obtained in this study indicate that extracts of leaves of A. occidentale irradiated at a dose of 10 kGy exhibit strong antioxidant activity against DPPH and power reducer, this paves its use as a natural source of antioxidants.

    The prevalence of diabetes mellitus is becoming more and more serious and reaches epidemic proportions worldwide. Scientific research is constantly looking for new agents that could be used as dietary functional ingredients in the fight against diabetes. The objective of the present study was to evaluate the effect of ethyl acetate fraction of Hibiscus rosa sinensis Linn. petals on experimental diabetes at a dose of 25 mg/kg body weight and it was compared with standard anti-diabetic drug metformin. The elevated levels of serum glucose (398.56 ± 35.78) and glycated haemoglobin (12.89 ± 1.89) in diabetic rats were significantly decreased (156.89 ± 14.45 and 6.12 ± 0.49, respectively) by Hibiscus rosa sinensis petals (EHRS) administration. Hepatotoxicity marker enzyme levels in serum were normalized. The fraction supplementation restored the glycogen content by regulating the activities of glycogen metabolizing enzymes. It significantly modulated the expressions of marker genes involved in glucose homeostasis signalling pathway. Histopathological analysis of liver and pancreas supported our findings. The overall effect was comparable with metformin. Hence, our study reveals the role of hibiscus petals for alleviation of diabetes complications, thus it can be propagated as a nutraceutical agent.

    Full Text Available Annona muricata Linn. (soursop is one of  tropical plants which have relatively complete chemical compounds. It has flavonoid, tannin, phytosterol, alkaloid, etc. The high antioxidant compound in soursop is believed as cancer prevention so the cancer threat in the world can be minimized. The antioxidant compound in soursop can be found not only in its fruit, but also in other parts like leaves, seeds, etc. Based on that potency, this study aimed to compare antioxidant capacity of soursop leaves and seeds, also to study about the utilization of soursop parts which is usually not used. This research began with maceration to extract leaves and seeds with 96% ethanol. Ethanolic extract of soursop leaves and seeds were then tested for antioxidant capacity with DPPH (1,1-diphenyl-2-picrylhydrazyl method. The result showed that antioxidant capacity of soursop leaves and seeds are 85,66875% and 39,0166, respectively. The antioxidant capacity of leaves is higher than seeds due to seed’s extraction difficulty so its antioxidant compound could not be extracted optimally. However, either leaves or seeds extract in this study are potential as antioxidant resources because there are no significant differences between antioxidant capacity of both extract.

    Full Text Available Background Hypertension and myocardial infarction account for the high rate of mortality globally. Hibiscus sabdariffa (HS Linn. is rich in antioxidants and previous studies have demonstrated its anti-hypertensive effects. Several studies show that regular physical activity is an important component to reduce cardiovascular mortality. The objective of this study was to evaluate the effects of a combination of aerobic exercise and HS extract on nitric oxide (NO and endothelin-1 (ET-1 in rats.   Methods An experimental study was conducted on 36 male Wistar rats, aged 4 weeks and 60-70 g in weight. The interventions were aerobic exercises and HS at 400 mg/kg BW/day administered for 4, 8 and 12 weeks. The rats were randomized into 12 groups: 3 control groups (C4, C8, C12, 3 aerobic exercise groups (A4, A8, A12, 3 HS groups (H4, H8, H12, and 3 combination groups [aerobic exercise and HS] (HA4, HA8, HA12. After 4, 8, and 12 weeks, the rats were sacrificed and their abdominal aorta was collected for determination of nitric oxide and ET-1 concentrations. One way ANOVA was used to analyze the data.   Results There was a significant difference in NO levels between all groups, with the 4-week aerobic exercise group (A4 showing the highest NO levels compared to the other eleven groups (p<0.05. In contrast, the ET-1 levels were not significantly different between all groups.   Conclusions This study demonstrated that the combination of HS supplementation and aerobic exercise increases NO in rats, and provided further evidence to the traditional use of the plant as an antioxidants agent.

    Full Text Available In continuation of the efforts for synthesizing silver nanoparticles (AgNPs by green chemistry route, here we report a facile bottom-up ‘green’ route for the synthesis of AgNPs using aqueous leaves extract of Urtica dioica (Linn.. The synthesized AgNPs were characterized by UV-vis spectroscopy, X-ray diffraction (XRD, Fourier transform-infrared spectroscopy (FTIR, Zeta-sizer and Zeta-potential, Scanning electron microscopy (SEM, Energy dispersive X-ray (EDX spectroscopy, Transmission electron microscopy (TEM and Selected area electron diffraction (SAED. The results obtained from various characterizations revealed that AgNPs were in the size range of 20–30 nm and crystallized in face-centered-cubic structure. The antibacterial activity against Gram-positive (Bacillus cereus, Bacillus subtilis, Staphylococcus aureus and Staphylococcus epidermidis and Gram-negative (Escherichia coli, Klebsiella pneumoniae, Serratia marcescens and Salmonella typhimurium bacterial pathogens was demonstrated by synthesized nanoparticles. Further, synergistic effects of AgNPs with various antibiotics were evaluated against above mentioned bacterial pathogens. The results showed that AgNPs in combination with antibiotics have better antibacterial effect as compared with AgNPs alone and hence can be used in the treatment of infectious diseases caused by bacteria. The maximum effect, with a 17.8 fold increase in inhibition zone, was observed for amoxicillin with AgNPs against S. marcescens proving the synergistic role of AgNPs. Therefore, it may be used to augment the activities of antibiotics.

    The plant Cocos nucifera Linn. (Arecaceae) is commonly known as coconut. Traditionally the juice of the young spadix when fresh is used in diarrhea and diabetes. The objective of the present study was to investigate the effect of antidiabetic activity and effect on lipid profile as well as cardioprotective effect of hydro-methanol extract of Cocos nucifera (HECN) on streptozotocin (STZ)-induced diabetic rats. After 72 h of STZ (50 mg/kg, b.w. i.p.) administration, animals showing plasma sugar level more than 250 mg/dl were considered as diabetic rat. Fasting blood glucose (FBG) levels were measured on 0th (after 72 h of STZ), 5th, 10th, and 15th day. On the 15th day all the animals were sacrificed and the serum biochemical parameters and antioxidant enzyme status were measured. HECN treated animals showed a significant reduction in FBG level as compared with diabetic control group. Serum enzyme level (SGOT, SGPT, SALP), lipid peroxidation and antioxidant enzyme level such as CAT, GSH, SOD and cholesterol and triglycerides in the HECN treated groups were restored towards normal level as compared to diabetic control groups and the values were comparable with the standard groups (glibenclamide). Improvement in the FBG and the restoration of all other biomarker as well as enzymes indicates that HECN has very good antidiabetic activity with very low side effects and provides a scientific rationale for the use as an antidiabetic agent.

    Full Text Available Lepidium latifolium Linn. (perennial pepperweed is one of the preferred phytofoods among cold arid region of Ladakh, India and its leaves contribute significantly to people's diet. This study was conducted to determine its nutritive value and antioxidant activity. Plant samples from three different locations were selected in the present study. Results showed that this plant is an excellent source of glucosinolates, notably sinigrin that is present in very high amount (∼70-90%. Its value ranged from 149 to 199 µg per g fresh weight. Fatty acid composition analysis showed that its leaves were abundant in unsaturated fatty acids, specifically linolenic acid (18∶3 whose percentage is about 50%. Higher glucose and crude protein along with higher nitrogen to sulfur ratio, supplements the nutritive value of this plant. Based on total phenol, flavanoids, free radical scavenging activity and DNA protective activity showed that this ecotype of perennial pepperweed contains high antioxidant properties. The percentage inhibition for O2(- scavenging activity ranged from 41.3% to 83.9%. Higher content of phenols (26.89 to 50.51 mg gallic acid equivalents per g dry weight and flavanoids (38.66 to 76.00 mg quercetin equivalents per g dry weight in leaves could be responsible for the free radical scavenging activity of this plant. Depending upon the location of the plants, variations were observed in different activities. Based on the systematic evaluation in this study, preparations of Lepidium latifolium from Ladakh can be promoted as substitute to dietary requirements.

    This research is designed to determine the efficacy of DBD plasma to reduce the microbial contamination of pepper and sesame powder. The AC high voltage power supply was used with voltages of up to 20 kV and the frequency of 5.5 kHz was applied to the DBD. The gap of DBD electrodes was set at 5 mm. In raw initial samples, the total aerobic count of pepper (Piper nigrum) was found at quite a high level at 5.40 × 105 CFU/g. Coliform bacteria was also found in both the sesame (Sesamum indicum Linn.) powder and pepper (Piper nigrum) powder. Both kinds of samples were treated with plasma for 2, 4, 6 and 10 minutes. Results indicated that plasma treatment at 2-10 minutes reduced the total aerobic count of pepper allowed to achieve the acceptable microbial level for spices. The plasma treatment times in this experiment were also effective in reducing faecal coliform bacteria in both pepper and sesame powders (MPN/g <3) as indicated in the standard. Plasma from dielectric barrier charge can reduce Staphylococcus epidermidis in sesame powder which was artificially contaminated with 3.50 × 102 CFU/g resulting in 0.15-0.5 log cycle reductions of microbial load.

    The case of diabetes mellitus (DM) tends to increase worldwide. DM triggers the oxidative stress condition that caused by the increasing of free radical. The present study was conducted to evaluate the effect of giving ethanolic extract of Lawsonia inermis (Linn) leaves to the glucose and malondialdehyde (MDA) level in alloxan-induced diabetic Wistar male rats. The powder of dry leaves of L.inermis was macerated in ethanol 96% to obtain ethanolic extract (LLEE).Thirty five of rats were divided into five groups, ie. K (normal and given 0.9% NaCl solution ), P1-P4 were induced using alloxan (120 mg/kg) intraperitoneally to get diabetic condition. Diabetic rats then were treated as follows: P1 (given 0.9% NaCl solution) P2 (LLEE (200 mg/kg BW), P3 (LLEE (400 mg/kg BW)), P4 ( LLEE (600 mg/kg BW)). All groups were treated for 28 days. The fasting blood glucose levels were measured at day 1, 7, 14, 21, 28 whereas MDA levels were measured at the end of treatment. The result showed that LLEE improved blood glucose level (BGLs) of alloxan-induced diabetic rats significantly (p 0.5). The study concluded that LLEE have antihyperglycemic properties.

    Calcium supplements can reduce the risk of osteoporosis, but they are not automatically absorbed in the gastrointestinal tract. Nanotechnology is presumed to have a capacity in resolving this problem. The preparation and characterization of calcium carbonate nano particle to improve the solubility was performed. Calcium carbonate nano particles were synthesized using precipitation method from cockle shells (Anadara granosa Linn). Samples of the cockle shells were dried in an oven at temperature of 50°C for 7 (seven) days and subsequently they were crushed and blended into fine powder that was sieved through 125-μm sieve. The synthesis of calcium carbonate nanocrystals was done by extracting using hydro chloride acid and various concentrations of sodium hydroxide were used to precipitate the calcium carbonate nano particles. The size of the nano particles was determined by SEM, XRD data, and Fourier transform infrared spectroscopy (FT-IR). The results of XRD indicated that the overall crystalline structure and phase purity of the typical calcite phase CaCO3 particles were approximately 300 nm in size. The method to find potential applications in industry to yield the large scale synthesis of aragonite nano particles by a low cost but abundant natural resource such as cockle shells is required.

    Full Text Available Ajisamat, an herb commonly used as an aphrodisiac in the Malaysian traditional medicine, corresponds to two different species from different families - Salacia macrophylla Blume, Celastraceae, and Prismatomeris glabra (Korth. Valeton, Rubiaceae. Macromorphological inspection of the vegetative parts both plants reveals only a slight difference in the arrangement of the petioles. Microscopic investigation of the plants roots used as crude drugs revealed however distinctive anatomical features. Prismatic calcium oxalate crystals and banded paratracheal parenchyma are characteristics of S. macrophylla while P. glabradisplays an abundance as crystals. Other features such as vessels diameters and arrangements are also of diagnostic importance. Some of these characters were also identified in the powder of thes e plant materials and proposed for diagnostic purpose. The values for extraction of ethanol and water as well as total ash, acid-insoluble ash, water-soluble ash and sulfated ash were determined for both plants. Phytochemical studies were carried out on hexane and chloroform extracts of S. macrophylla and methanolic extract of P. glabra. S. macrophylla was shown to contain highly oxidized pentacyclic triterpenes while P. glabra contains anthraquinones. The pharmacognostical and hytochemical information can be utilised as the identification tools for Salacia macrophylla and Prismatomeris glabra

    The present study aimed to determine the antioxidant activity and phytochemical contents in 10 underutilized fruits of Andaman Islands (India) namely Malpighia glabra L., Mangifera andamanica L., Morinda citrifolia L., Syzygium aqueum (Burm.f) Alst., Annona squamosa L., Averrhoa carambola L., Averrhoa bilimbi L., Dillenia indica L., Annona muricata L. and Ficus racemosa L. The antioxidant activity varied from 74.27% to 98.77%, and the methanol extract of M. glabra showed the highest antioxidant activity (98.77%; inhibitory concentration, IC(50) = 262.46 μg/ml). Methanol was found to be a better solvent than acetone and aqueous for estimating the antioxidant activity. M. glabra was found to be rich in phytochemicals viz. polyphenol (355.74 mg/100 g), anthocyanin (91.31 mg/100 g), carotenoids (109.16 mg/100 g), tannin (24.39 mg/100 g) and ascorbic acid (394.23 mg/100 g). Carbohydrate content was estimated to be highest in M. glabra (548 mg/100 g). Phenols, tannins, anthocyanins and carotenoids contents showed positive correlation (r² = 0.846, r² = 0.864, r² = 0.915 and r² = 0.806, respectively) with antioxidant activity. The information generated in present study will be useful for bioprospecting of underutilized fruits of Andaman Islands.

    Plant materials rich in phenolic compounds, such as Anacardium occidentale Linn., Have been used as alternatives to synthetic pesticides in Biomphalaria glabrata control programs, intermediate host of Schistosoma mansoni. Studies show that ionizing radiation can influence the content of phenolic compounds and thus their biological actions. The aim of this study was to evaluate the influence of gamma radiation of {sup 60}Co in polyphenol composition of hydroalcoholic extracts of bark and leaves of A. occidentale and evaluate the toxicity of these extracts to embryos and adults of B. glabrata. To achieve this goal this, the extracts were irradiated at 10 kGy, the controls being maintained from 0 kGy and positive (CaCO{sub 3}) and negative (H{sub 2}O). We quantified the total phenols by the Folin-Ciocalteau and tannins by precipitation of casein. Extracts were used at a concentration of 100 mg/L. The results showed that the radiation caused the changes to the leaves, the percentage of polyphenols and tannins, and the percentage of lethality in embryos and adults Biomphalaria glabrata, these percentages being: 13 ± 5 (0 kGy) and 27 ± 2.5 (10 kGy), and 36.67 ± 5.77 (0 kGy), and 56.67 ± 5.77 (10 kGy), respectively. Gamma radiation caused significant changes in the levels of polyphenols in the extracts of leaves of Anacardium ocidentale Linn., translated by the increased toxicity of this extract against embryos and adults of Biomphalaria glabrata. This indicates that gamma radiation can be used as an agent potentiating the toxicity of plant extracts on the alternate use of these materials as molluscicides. (author)

    In the traditional medicine, Cynodon dactylon (Linn.) is used in asthma, but scientific studies to provide evidence for medicinal uses are sparse. Thus this study was undertaken to provide evidence for medicinal use in asthma as a bronchodilator, and to identify active ingredient(s). In vivo, acetylcholine (Ach)-induced bronchospasm was conducted in guinea pig while isolated rat tracheal strip was suspended in organ bath to measure the concentration response curve using multichannel data acquisition system. The chloroform extract of Cynodon dactylon (CECD) protected against Ach-induced bronchospasm in guinea pigs, similar to atropine. In the in vitro studies, CECD relaxed carbachol (CCh) and high K+-induced contraction of rat tracheal strip, similar to atropine and verapamil respectively, suggesting antimuscarinic and calcium channel blocking (CCB) activities, which were confirmed by right ward shifting of CCh and Ca(+2) concentration response curve (CRC). The phosphodiestrase (PDE) inhibitory activity was confirmed by potentiation of isoprenaline-induced inhibitory response, similar to papaverine. Densitometry analyses led to the identification of scopoletin as an active ingredient. Effectively, it significantly inhibited high K+, and Ca(+2) induced contractile response, similar to verapamil. The phosphodiestrase (PDE) inhibitory activity was confirmed by direct evidence of potentiation of isoprenaline-induced inhibitory response, similar to papaverine. These results suggest that the bronchodilator activity of CECD is partly due to presence of scopoletin, and mediated possibly through CCB and PDE inhibition.

    Full Text Available The bottom dwelling air-breathing catfish, Clarias batrachus (Linn. also respires via its skin (an accessory water-breathing organ. Prolonged (90 days exposure to disodium arsenate heptahydrate has caused massive damage (e.g. wear and tear of various cellular components including club cells, hypertrophy and hyperplasia of the goblet mucous cells, altered staining and the slimy secretion to the epidermis of its skin. The present study investigated the recovery in architecture of the damaged epidermis following return of the 90 days disodium arsenate heptahydrate exposed fish to clean water. The significant regeneration of its different cellular components (epithelial cells, Club cells, Mucous cells took place after 24 h of withdrawal when sloughing; wear and tear and other damages of the epidermis of the skin got substantially reduced. The histopathological alterations which still continued included squeezing out of contents of the Club cells that formed a thin layer on the body surface. Regeneration of the Club cells continued throughout the epidermis even though the newly formed Club cells still showed massive sign of degeneration. Altered staining behaviour and hyperactivity of the Mucous cells continues even after prolonged withdrawal of the stress of the arsenic salt. Similarly the glycoproteins of the slime secreted by the mucous cells retained their sulphate moieties. This indicates that disodium arsenate heptahydrate induces certain permanent non-reversible damages including altered mucogenic activity in the epidermis of the skin of C. batrachus.

    Introduction: Present work, is an effort toward exploring the potential of Cassia fistula Linn. seed gum as an extended release polymer and laxative. While, C. fistula pulp polymer has evaluated as suspending agent. Materials and Methods: For extended release application, total five batches (F1-F5) were prepared by varying the ratio of drug:polymer as 1:1, 1:2, 1:3, 1:4, and 1:5, respectively. The granules were prepared by wet granulation method and further evaluated for micromeritic properties such as angle of repose (θ), Carr's compressibility index (CCI), and Hausner's ratio. Further compacts were evaluated by hardness, thickness, swelling index, in-vitro dissolution, and so on. Laxative activity was evaluated by administration of seed polymer (100 mg/kg) alone or in combination with bisacodyl (2.5 mg/kg) in 1% Tween 80. Zinc oxide suspension was prepared by varying the concentration of C. fistula pulp polymer and compared with suspension made by use of tragacanth, sodium carboxymethyl cellulose and bentonite. Results: Result showed that granules were free flowing, while the compact extended the drug release up to 10 h (72.84 ± 0.98; batch F5) and followed Higuchi matrix release kinetics. This extended release might be due to the formation of polyelectrolyte complex because of gluco-mannose in seed gum. Result of in-vivo laxative activity showed that seed polymer reduced faeces weight after 24 h compared to control (P < 0.01). Conclusions: Pulp polymer showed good sedimentation volume, but alone fails to stabilize the suspension for a longer period, so it could be useful in combination with other suspending agents and can be useful as novel excipient.

The present study aimed to analyze and compare the dipterofauna that visit or colonize carcasses in the urban and coastal areas of São Paulo, Brazil, during summer and winter seasons. Four swine (Sus scrofa Linné, 1758 carcasses of approximately 12 kg were used. The animals were previously euthanized and then placed in metal cages covered with a flight intercept trap (Shannon, modified. In total, 10,495 flies from 39 families were collected, with 15 species belonging to the Calliphoridae family, 14 species belonging to the Fanniidae family, 43 species belonging to the Muscidae family, and 22 species belonging to the Sarcophagidae family. Flies from these four families visited all carcasses; however, they did not show the highest visitation frequencies in all of the trials. Species variations occurred between the experiments that were performed at different locations and in different seasons. Furthermore, difference in the number of insects attracted to each stage of decomposition was observed. In addition to the four families highlighted above, the families Phoridae, Sepsidae, Otitidae, and Piophilidae were observed in all carcasses.

    P-coumaric acid is a nonflavonoid phenolic acid and is a major constituent of the species Cynodon dactylon Linn. (Pers.). In this study isolation of P-coumaric acid was achieved by preparative TLC and the compound thus isolated was characterised by UV, mass, and H1 NMR spectral analysis. An isocratic RP-HPLC method was developed for the estimation of P-coumaric acid from methanolic extracts of durva grass. The chromatographic separations were achieved by RP-C18 column (250 mm × 4.6 mm, 5 μ), Shimadzu LC-20AT Prominence liquid chromatograph, and a mobile phase composed of water : methanol : glacial acetic acid (65 : 34 : 1 v/v). The flow rate was 1.0 mL/min and the analyses of column effluents were performed using UV-visible detector at 310 nm. Retention time of P-coumaric acid was found to be 6.617 min. This method has obeyed linearity over the concentration range of 2–10 μg/mL and the regression coefficient obtained from linearity plot for P-coumaric acid was found to be 0.999. RP-HPLC method was validated in pursuance of ICH guidelines. PMID:25788944

    The purpose of this study is to use a molecular docking approach to identify potential estrogen mimics or anti-estrogens in phytochemicals found in popular dietary herbal supplements. In this study, 568 phytochemicals found in 17 of the most popular herbal supplements sold in the United States were built and docked with two isoforms of the estrogen receptor, ERα and ERβ (a total of 27 different protein crystal structures). The docking results revealed six strongly docking compounds in Echinacea, three from milk thistle (Silybum marianum), three from Gingko biloba, one from Sambucus nigra, none from maca (Lepidium meyenii), five from chaste tree (Vitex agnus-castus), two from fenugreek (Trigonella foenum-graecum), and two from Rhodiola rosea. Notably, of the most popular herbal supplements for women, there were numerous compounds that docked strongly with the estrogen receptor: Licorice (Glycyrrhiza glabra) had a total of 26 compounds strongly docking to the estrogen receptor, 15 with wild yam (Dioscorea villosa), 11 from black cohosh (Actaea racemosa), eight from muira puama (Ptychopetalum olacoides or P. uncinatum), eight from red clover (Trifolium pratense), three from damiana (Turnera aphrodisiaca or T. diffusa), and three from dong quai (Angelica sinensis). Of possible concern were the compounds from men's herbal supplements that exhibited strong docking to the estrogen receptor: Gingko biloba had three compounds, gotu kola (Centella asiatica) had two, muira puama (Ptychopetalum olacoides or P. uncinatum) had eight, and Tribulus terrestris had six compounds. This molecular docking study has revealed that almost all popular herbal supplements contain phytochemical components that may bind to the human estrogen receptor and exhibit selective estrogen receptor modulation. As such, these herbal supplements may cause unwanted side effects related to estrogenic activity.

    Many plants are known to have beneficial therapeutic effects as noted in the traditional Indian system of medicine, Ayurveda and used since time immemorial for curing diseases. Even today, nearly 70% of the world's population is dependent on plants for handling their health related problems and plants have been utilized successfully for the treatment of free radical-mediated diseases in human such as Rheumatoid arthritis, Atherosclerosis, Cancer, Alzheimer's disease, Parkinson's disease, aging and several other conditions including inflammatory diseases. Plant extracts eliciting radio protective efficacy contain a plethora of compounds including antioxidants, immunostimulants, cell proliferation stimulators, anti-inflammatory and antimicrobial agent, some of which may act in isolation as well as in combination with other constituents from the same plants. Glycyrrhiza glabra, Allium sepa, Allium sativum, Aloe arborescens, Amaranthus paniculatus, Curcuma longa, Moringa olefera and Syzygium cumini are some important radio protective plants. Alium sativum has been reported to possess antioxidant antimicrobial, antitumor, antimutagenic and anti-inflammatory properties. Aloe arborescens acts as a cell proliferate, healer and allergy reducer. Amaranthus paniculatus is used for purifying blood and treating scrofulous sores. Curcuma longa is widely used in antitumor and antibacterial activities. Leaf extract of Moringa oleifera is significantly used in nervous debility and healing of wound. Chlorella is well known nutrient dense superfood that contains 60% protein, 18 amino acids (including all the essential amino acids), more than 20 vitamins and minerals. Chlorell has been used to treat cancer and also protect the body from the effects of cancer radiation treatment due to its chlorophyll in abundance level. However they have little attention for their radio protective as well as antioxidant. There is an urgent need to develop newer, more efficient and reliable bioassays

    In the present study, glycyrrhizic acid (GA) the main component of Glycyrrhiza glabra was evaluated for its efficacy as antileishmanial agent and its mode of action explored. GA inhibits promastigotes and intracellular amastigotes in a dose dependent manner at an IC 50 value of 34 ± 3.0 μM and 20 ± 4.2 μM respectively. GA was non-toxic against THP-1 macrophage host cell line. GA was found to inhibit recombinant Leishmania donovani HMG-CoA reductase (LdHMGR) enzyme at the half-maximum inhibitory concentration of 24 ± 4.3 μM indicating the sensitivity and specificity of GA towards the enzyme. However, GA could cause only 30% reduction in HMGR activity when measured in Leishmania promastigotes treated with 34 μM of GA. Interestingly western blot analysis revealed fivefold reduced HMGR expression in GLA treated promastigotes. To further study the mode of action of GA, we used transgenic parasites overexpressing LdHMGR. Results indicated that ∼2 fold resistance was exhibited by LdHMGR overexpressing promastigotes to GA with an IC 50 value of 74 μM compared to the wild type parasite. This explained the specific binding of GA to LdHMGR enzyme. There was ∼2 fold depletion in ergosterol levels in wild type promastigotes compared to the HMGR overexpressors. This data was further validated by exogenous supplementation of GA treated cells with ergosterol and 40% reversal of growth inhibition was observed. The results obtained suggested that GA kills the parasite by affecting sterol biosynthetic pathway, especially by inhibiting the L. donovani HMGR and altering ergosterol levels. The finding from the current study shows that GA is a potential antileishmanial chemotherapeutic agent. Copyright © 2017 Elsevier Inc. All rights reserved.

    Context • The cough is a protective reflex, with 2 types, one being more sensitive to mechanical stimulation and the other to chemical stimulation, such as sulfur dioxide, ammonia, citric acid, and capsaicin. Some evidence is available that suppressant therapy is most effective when used for the short-term reduction of coughing. Today, use of herbal drugs is increasing all over the world for various ailments, including to provide antitussive activity. Objective • The study intended to review the antitussive effects of various extracts, some fractions, and some constituents of the studied medicinal plants. Design • Various databases, including the Medline, Science Direct, Scopus, and Google Scholar, were searched for studies published between 1978 and 2015, using the keywords antitussive and cough and the names of various medicinal plants and their constituents. Setting • The study took place in the districts related to Mashhad University of Medical Sciences (Mashhad, Iran). Outcome Measures • The antitussive effects of medicinal plants and their constituents were normalized to 50 mg/kg and 1 mg/mL against various cough stimulants and compared. Results • The most potent antitussive effect was observed for Nigella sativa and Linum usitatissimum on coughs induced by sulfur dioxide. Artemisia absinthium showed a higher antitussive effect on cough induced by ammonia compared with the other studied medicinal plants. The antitussive effects of Cuminum cyminum and Glycyrrhiza glabra were more potent on cough induced by citric acid than other medicinal plants. Conclusions • These results suggest the therapeutic potential of the studied medicinal plants as antitussive therapies. However, only a few clinical studies have examined the antitussive effects of medicinal plants, and more clinical studies are needed. The underlying mechanisms of the antitussive effects of medicinal plants should be also examined in further studies.

    The total phenolic and flavonoid content and percentage of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of callus and in vivo plant parts of Heliotropium indicum Linn. were estimated. Murashige and Skoog (MS) basal medium supplemented with α-naphthaleneacetic acid (NAA) 2.0 mg/l with benzyladenine (BA) 0.5 mg/l showed the highest amount of callus biomass (1.87 g/tube). The morphology of callus was significantly different according to the plant growth regulators and their concentrations used in the medium. The highest amount of total phenolic (21.70 mg gallic acid equivalent per gram (GAE/g)) and flavonoid (4.90 mg quercetin equivalent per gram (QE/g)) content and the maximum percentage (77.78 %) of radical scavenging activity were estimated in the extract of inflorescence. The synergistic effect of NAA (2.0 mg/l) and BA (0.5 mg/l) enhances the synthesis of total phenolic (9.20 mg GAE/g) and flavonoid (1.25 mg QE/g) content in the callus tissue. The callus produced by the same concentration shows 45.24 % of free radical scavenging activity. While comparing the various concentrations of NAA with 2,4-dichlorophenoxyacetic acid (2,4-D) for the production of callus biomass, total phenolic and flavonoid content and free radical scavenging activity, all the concentrations of NAA were found to be superior than those of 2,4-D.

    Full Text Available Abstract Background The aqueous-methanolic extract of Amaranthus spinosus (A. spinosus Linn., whole plant, was studied for its laxative, spasmolytic and bronchodilator activities to validate some of its medicinal uses. Methods The crude extract of A. spinosus was studied in-vivo for bronchodilator and laxative activities and in-vitro using isolated tissue preparations which were mounted in tissue baths assembly containing physiological salt solutions, maintained at 37°C and aerated with carbogen, to assess the spasmolytic effect and to find out the possible underlying mechanisms. Results In the in-vivo experiments in mice, the administration of A. spinosus increased fecal output at doses of 100 and 300 mg/kg showing laxative activity. It also inhibited carbachol-induced bronchospasm in anesthetized rats at 1, 3, 10 and 30 mg/kg indicative of bronchodilator activity. When tested on isolated gut preparations, the plant extract showed a concentration-dependent (0.01-10.0 mg/ml spasmogenic effect in spontaneously contracting rabbit jejunum and guinea-pig ileum. The spasmogenic effect was partially blocked in tissues pretreated with atropine (0.1 μM. When tested on K+ (80 mM-induced sustained contractions in isolated rabbit jejunum, the plant extract caused complete relaxation and also produced a shift in the Ca++ concentration-response curves (CRCs towards right, similar to diltiazem. In rabbit trachea, the plant extract completely inhibited K+ (80 mM and carbachol (CCh, 1 μM-induced contractions at 1 mg/ml but pretreatment of tissue with propranolol (1 μM, caused around 10 fold shift in the inhibitory CRCs of the plant extract constructed against CCh-induced contraction. The plant extract (up to 0.3 mg/ml also increased both force and rate of spontaneous contractions of isolated guinea-pig atria, followed by relaxation at higher concentration (1.0-5.0 mg/ml. The cardio-stimulant effect was abolished in the presence of propranolol, similar to

    Full Text Available Dengue, a mosquito-borne viral disease, poses a significant global public health risk. In tropical countries such as India where periodic dengue outbreaks can be correlated to the high prevalence of the mosquito vector, circulation of all four dengue viruses (DENVs and the high population density, a drug for dengue is being increasingly recognized as an unmet public health need.Using the knowledge of traditional Indian medicine, Ayurveda, we developed a systematic bioassay-guided screening approach to explore the indigenous herbal bio-resource to identify plants with pan-DENV inhibitory activity. Our results show that the alcoholic extract of Cissampelos pariera Linn (Cipa extract was a potent inhibitor of all four DENVs in cell-based assays, assessed in terms of viral NS1 antigen secretion using ELISA, as well as viral replication, based on plaque assays. Virus yield reduction assays showed that Cipa extract could decrease viral titers by an order of magnitude. The extract conferred statistically significant protection against DENV infection using the AG129 mouse model. A preliminary evaluation of the clinical relevance of Cipa extract showed that it had no adverse effects on platelet counts and RBC viability. In addition to inherent antipyretic activity in Wistar rats, it possessed the ability to down-regulate the production of TNF-α, a cytokine implicated in severe dengue disease. Importantly, it showed no evidence of toxicity in Wistar rats, when administered at doses as high as 2g/Kg body weight for up to 1 week.Our findings above, taken in the context of the human safety of Cipa, based on its use in Indian traditional medicine, warrant further work to explore Cipa as a source for the development of an inexpensive herbal formulation for dengue therapy. This may be of practical relevance to a dengue-endemic resource-poor country such as India.

    Background: Leonotis nepetifolia Linn (Lamiaceae) is used in traditional medicine for its calming (tranquilizing) effects. The aim of this study was to determine whether there is any scientific justification for this use. To achieve this purpose, we investigated the behavioural effects of the methanol extract of Leonotis nepetifolia stem (37.5, 75 and 150 mg/kg) in mice. Methods: Acute toxicity studies were carried out on the methanol stem extract of Leonotis nepetifolia to determine the LD50. The behavioural tests employed were diazepam-induced sleep onset and duration, hole board assay for exploratory activity, mouse beam walk assay for motor coordination, and the staircase test for the detection of anxiolytic compounds. Preliminary phytochemical screening was also carried out on the extract. Results: The intraperitoneal LD50 value was found to be 3.8 g/kg. The results showed that the extract significantly prolonged the duration of diazepam-induced sleep at the highest dose (150 mg/kg). There was no observable effect on exploratory activity and motor coordination at the doses tested (37.5, 75 and 150 mg/kg). The extract, however, at 150 mg/kg elicited a significant decrease in the number of rearings in the staircase test, an effect also observed in the group of mice injected with an anxiolytic dose of diazepam. The preliminary phytochemical screening revealed the presence of alkaloids, saponins, glycosides and triterpenoids. Conclusion: The results obtained suggest that the crude methanol extract of Leonotis nepetifolia stem possesses some biologically active constituents with potential anxiolytic activity and thus may justify its traditional use as a tranquilizer.

    Ocimum sanctum Linn (Sanskrit: Tulasi; family: Libiaceae), popularly known as holy basil or Ocimum teinufolium, is found throughout the semitropical and tropical parts of India. In Ayurveda, Tulasi has been well known for its therapeutic potentials. To optimise and develop a standard method to quantify seven polyphenols simultaneously by HPTLC. A three-level factor Box-Behnken statistical design was used for optimisation, where extraction time (min), temperature (°C) and methanol:water ratio (% v/v) are the independent variables with polyphenols as the dependent variable. The separation was archived on a silica-gel 60 F254 HPTLC plate using toluene:ethyl acetate:formic acid:methanol (3:3:0.8:0.2 v/v) as the mobile phase. Densitometric analysis of polyphenols was carried out in the absorbance mode at 366 nm. The quantification of polyphenols was carried out based on peak area with a linear calibration curve at concentration ranges of 60-240, 20-200, 100-1600, 40-200, 200-1400, 10-160, 200-1400, 100-5000 ng/band for caffeic acid, ellagic acid, rutin, kaempferol, catechin, quercetin, eupalitin and epicatechin respectively. The method was validated for peak purity, precision, accuracy, limit of detection (LOD) and quantification (LOQ). Method specificity was confirmed using the retention factor value and visible spectra correlation of marker compounds. A validated HPTLC method was newly developed for simultaneous quantification of seven polyphenols in an Ayurvedic preparation of O. sanctum. The proposed method is simple, precise, specific, accurate, cost-effective, less time consuming and has the ability to separate the polyphenols from other constituents.

    Anacardium occidentale Linn. is popularly known as cashew plant, found in Northeastern Brazil, is of great scientific interest because it contains high levels of bioactive compounds, such as polyphenols, flavonoids and tannins, which characterize their applications as natural antioxidants, which can contribute to protect against oxidative processes in the human body. This study aimed to evaluate the effects of 60 Co gamma irradiation in the antioxidant action of the extracts of leaves of A. occidentale. The extracts of A. occidentale were extracted with 70% ethanol, evaporated under reduced pressure and divided into samples control and irradiation at 10 kGy. Subsequently analyzing the kidnapping of radical DPPH (concentrations of 6.25; 12.5; 25; 50; 100 and 200 ppm) and reducing power (concentrations of 25; 50; 100; 200; 400; 600; 800 and 1000 ppm). The results showed increased antioxidant actions dependent on the concentration and dose of 10 kGy in both assays. However, the kidnapping of DPPH activity showed variations from 50% to 92% for control, and 75% and 100% for irradiated. It is observed that the irradiated samples showed maximum activity (100%) in a 4-fold lower concentration (50 ppm) than the control samples. Featuring EC 50 of standards BHT (235.8%) and vitamin C (63.5%) was very low compared with control extracts (8.1%) and irradiated (0.48). However the results obtained in this study indicate that extracts of leaves of A. occidentale irradiated at a dose of 10 kGy exhibit strong antioxidant activity against DPPH and power reducer, this paves its use as a natural source of antioxidants

    To investigate the studies on effects of Andrographis paniculata (A. paniculata) (Burm.f.) and Andrographis lineata (A. lineata) nees (Family: Acanthaceae) extracts against two mosquitoes Culex quinquefasciatus (Cx. quinquefasciatus) (Say.) and Aedes aegypti (Ae. aegypti) (Linn.). The aqueous and petroleum ether extracts of two plant species, A. paniculata and A. lineate were examined against the larvae of A. aegypti (L.) and Cx. quinquefasciatus with gradually increasing concentration ie. from 50 to 200 ppm of solvent extracts and to test their activity in combination with each other. In a 24 h bioassay experiment with plant extracts, highest mortalities were recorded at 200 ppm of concentrations for leaves of A. lineta and A. paniculata individually. For combination effect, only 150 ppm of the mixture of solvent extracts of petroleum ether: aqueous (1:1) extracts showed 100% mortality after 24 h of exposure. The results show that, insecticides of plant combination is ecofriend and has better larvicidal activity compared to individual extracts. Copyright © 2013 Hainan Medical College.

    Full Text Available Essential oils of different species of the genus Ocimum are natural flavouring materials of commercial importance. The data given in current literature are pertaining to the chemical composition of essential oils of different Ocimum species viz., Ocimum basilicum Linn. (alt. Ocimum basilicum var. minimum, Ocimum basilicum var. purpurience, Ocimum campechianum Mill., Ocimum canum Sims. (Ocimum americanum, Ocimum citriodorum, Ocimum gratissimum Linn., Ocimum kilimandscharicum Linn., Ocimum micranthum Willd., Ocimum sanctum Linn., (alt. Ocimum tenuiflorum Linn., Ocimum selloi Benth., Ocimum trichodon, Ocimum utricifolium from different geographical regions. A considerable difference in chemical composition of a particular species is found, which may be due to their occurrence in different eco-climatic zones and changes in edaphic factors. Attention is also focused on the biological properties of Ocimum oils which are related to their various interesting applications as antimicrobial, antioxidant, repellent, insecticidal, larvicidal, nematicidal and therapeutic (anti-inflammatory, antinociceptive, antipyretic, antiulcer, analgesic, anthelmintic, anticarcinogenic, skin permeation enhancer, immunomodulatory, cardio-protective, antilipidemic agents.

    Development of newer improved therapeutic agents with efficient antimicrobial activities continues to draw attention of researchers till date. Moreover, abatement of polluting dyes released from industry with enhanced efficiency is currently being considered as challenging task for people working on material sciences. In the present study, we report a facile biogenic synthesis of gold and silver nanoparticles (NPs) in which aqueous extracts of Paederia foetida Linn. was used as reducing as well as stabilizing agent. The biosynthesized Au and Ag NPs were characterized by UV-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction analysis (XRD) and transmission electron microscopy (TEM). The photocatalytic activity of these nanoparticles were tested against Rhodamine B (RhB). The antimicrobial activity of these biosynthesized NPs were investigated against four human pathogens viz. B. cereus, E. coli, S. aureus and A. niger. Biogenic silver nanoparticles presented a strong antimicrobial activity against B. cereus (26.13) followed by E. coli (26.02), S. aureus (25.43) and A. niger (22.69). Ag NPs owing to their small size (5-25nm) could have easily penetrate into the cell membrane, disturb the metabolism, cause irretrievable damage finally leading to the microbial cell death. Interestingly biogenic gold nanoparticles didn't show any antimicrobial activity. Copyright © 2017 Elsevier B.V. All rights reserved.
