    Full Text Available Abstract Background The objective of present study was to provide the pharmacological basis for the medicinal use of Morinda citrifolia Linn in dyslipidemia using the aqueous-ethanolic extracts of its fruits (Mc.Cr.F, leaves (Mc.Cr.L and roots (Mc.Cr.R. Results Mc.Cr.F, Mc.Cr.L and Mc.Cr.R showed antidyslipidemic effects in both triton (WR-1339 and high fat diet-induced dyslipidemic rat models to variable extents. All three extracts caused reduction in total cholesterol and triglyceride levels in triton-induced dyslipidemia. In high fat diet-induced dyslipidemia all these extracts caused significant reduction in total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C, atherogenic index and TC/HDL ratio. Mc.Cr.R extract also caused increase in high density lipoprotein-cholesterol (HDL-C. The Mc.Cr.L and Mc.Cr.R reduced gain in body weight with a reduction in daily diet consumption but Mc.Cr.F had no effect on body weight and daily diet consumption. Conclusions These data indicate that the antidyslipidemic effect of the plant extracts was meditated through the inhibition of biosynthesis, absorption and secretion of lipids. This may be possibly due partly to the presence of antioxidant constituents in this plant. Therefore, this study rationalizes the medicinal use of Morinda citrifolia in dyslipidemia.

    In the present work, we describe the synthesis of gold nanoparticles using an aqueous root extract of Morinda citrifolia. UV-vis spectroscopy, XRD, FTIR, FE-SEM, EDX and TEM were performed to characterize the formation of gold nanoparticles. The synthesized gold nanoparticles were characterized by a peak at 540 nm in the UV-vis spectrum. The XRD peaks at 38°, 44°, 64° and 77° can be indexed to the (1 1 1), (2 0 0), (2 2 0) and (3 1 1) Bragg's reflections of cubic structure of metallic gold, respectively. The FTIR result showed that extract containing protein might be responsible for the formation of the nanoparticles and may play an important role in the stabilization of the formed nanoparticles. FESEM images revealed that the particles were triangle and mostly spherical in shape. TEM images clearly revealed the size of the nanoparticles were 12.17-38.26 nm in size.

    Full Text Available Soxhlet, Ultrasonic extract of Morinda citrifolia L. fruit and four extracts from high pressure extraction at 10 MPa using ethanol, ethyl acetate as solvent and dried by vacuum oven and spray dryer were analyzed for their antioxidant activity by peroxide value method and diphenylpicrylhydrazyl radical scavenging method. The five extracts along with the reference samples, butylated hydroxyl toluene and tannic acid were further analyzed to determine their total phenolic content by Folin-Ciocalteau method and total flavonoid content by Dowd method. The M. citrifolia extract by high pressure extraction with ethyl acetate as solvent and spray dried was found to exhibit highest antioxidant activity and total flavonoid content. High total phenolic content was determined in the high pressure extract using ethyl acetate as solvent and vacuum dried. It was interesting to note that ultrasonic extract exhibited significant antioxidant activity, total phenolic and flavonoid content. High pressure extracted M. citrifolia in ethanol was found to express lesser values comparatively. The significant difference in activity among the high pressure extracts was found to be due to the polarity of the solvents used for extraction as M. citrifolia fruit contains relatively larger quantity of non-polar antioxidant compounds. It was also found that the drying methods had significant impact on the antioxidant activity, total phenolic and flavonoid content of the extracts.

    Morinda citrifolia L. has been used for the treatment of a wide variety of diseases, including cancer. This study was undertaken to evaluate the anti-angiogenic effect of M. citrifolia fruits and leaves. Anti-angiogenic activity was evaluated in vivo using the chick chorioallantoic membrane assay. Bioactivity-guided fractionation and isolation were performed to identify the active constituent, and high-performance liquid chromatography analysis was then used to quantify the amount of this active constituent in the active extracts and fraction. The methanol extracts of fruits and leaves of M. citrifolia and the subsequent chloroform fraction of the fruit methanolic extract were found to have potential anti-angiogenic activity and were more potent compared to suramin. Scopoletin was identified as one of the chemical constituents that may be partly responsible for the anti-angiogenic activity of M. citrifolia fruits. The present findings further support the use of M. citrifolia in cancer or other pathological conditions related to angiogenesis.

    Full Text Available Slight decrease of hemoglobin and erythrocyte count was observed previously after subchronic oral dosing of Morinda citrifolia L leaves extract in rats. Induction of erythrocyte membrane damage could be the cause for these effects. Aims: The objective of this investigation was to assess the in vitro cytotoxicity of Morinda citrifolia L leaves extract and fractions on rat erythrocytes. Methods: Hemolytic damage was assayed in rat erythrocytes. Oxidative stress was assessed by measuring methemoglobin formation, thiobarbituric acid reactive substances (TBARS and enzyme antioxidant activities, superoxide dismutase (SOD and catalase (CAT. Results: Morinda citrifolia L extract caused no hemolysis and induced oxidative damage to red cells in vitro. Methemoglobin increase was observed at concentration between 2 and 8 mg/ml of the extract. Lipid peroxidation was increased and CAT and SOD activities were depleted indicating a possible increase of hydrogen peroxide and superoxide radicals in erythrocytes. Ethyl acetate, dichloromethane and butanol fraction did not cause methemoglobin formation while water fraction increased methemoglobin level at doses up to 6 mg/ml. Conclusions: We concluded that high doses of Morinda citrifolia L extract promote erythrocyte oxidative damage due to metabolites present in water fraction. These could be the cause of decreased erythrocyte and hemoglobin levels observed. [J Intercult Ethnopharmacol 2013; 2(3.000: 135-140

    The aim of this study was to investigate the effect of Morinda citrifolia fruit on blood fluidity. M. citrifolia fruit extract (MCF-ext) was investigated for its influence on blood aggregation and fibrinolysis. MCF-ext inhibited polybrene-induced erythrocyte aggregation and thrombin activity. The fibrinolytic activity of MCF-ext, in the euglobulin lysis time test and fibrin plate assay, is reported here for the first time. One of the active compounds was an iridoid glycoside, asperulosidic acid. The results indicated that MCF-ext is a potentially useful health food which is capable of improving blood flow and preventing lifestyle-related diseases.

    Morinda citrifolia Linn. (Rubiaceae) leaves have been used in tropical folk medicine to treat topical inflammation and burns. A carbomer gel base, containing the ethanol extract and juice pressed from the leaves, was evaluated for potential allergenic properties in a repeat-insult patch test in 49 volunteers. To investigate the topical photo-protective properties, the combined ethanol extract and leaf juice were evaluated in a UVB-induced erythema model in 25 volunteers. The crude ethanol extract of M. citrifolia leaves was also evaluated in vitro for potential anti-inflammatory activity in a histamine H-1 receptor antagonism assay. There was no evidence of allergenic potential in the repeat-insult patch test. When the combination of ethanol extract and leaf juice was applied, the UVB dose required to induce erythema was almost 3.5 times greater than with untreated skin (P citrifolia leaves inhibited receptor binding by 57%. These results suggest that M. citrifolia leaves are safe for topical use and may be useful in mitigating UVB-induced injury to the skin.

    Morinda citrifolia, commonly known as noni, is a traditional natural medicine in French Polynesia and Hawaii. Functional foods derived from M. citrifolia fruit have been marketed to help prevent diseases and promote good health. The objective of this study was to assess the effects of M. citrifolia fruit on cell-mediated immunity. In the picryl chloride-induced contact dermatitis test, M. citrifolia fruit extract (Noni-ext) inhibited the suppression of cell-mediated immunity by immunosuppressive substances isolated from freeze-dried ascites of Ehrlich carcinoma-bearing mice (EC-sup). In addition, Noni-ext inhibited reduction of IL-2 production in EC-sup-treated mice and activated natural killer cells in normal mice. These results suggest that Noni-ext has multiple effects on the recovery of cell-mediated immunity. Furthermore, we investigated the active principles of Noni-ext and identified an iridoid glycoside, deacetylasperulosidic acid. Oral administration of deacetylasperulosidic acid inhibited the reduction of ear swelling, and also cancelled the suppression of IL-2 production along with the activation of natural killer cells in the same manner as that of Noni-ext.

    Herbal drugs have been used since ancient times to treat a wide range of diseases. Morinda citrifolia Linn (popularly known as "Noni") has been used in folk medicine by Polynesians for over 2,000 years. It is reported to have a broad range of therapeutic effects, including effects against headache, fever, arthritis, gingivitis, respiratory disorders, infections, tuberculosis, and diabetes. The aim of this study was to investigate the antioxidant, anti-inflammatory, antinociceptive, and antibacterial properties of the aqueous extract from M. citrifolia leaves (AEMC). Antioxidant activity was observed against lipid peroxidation, nitric oxide, and hydroxyl radicals. The antinociceptive effect of AEMC was observed in the acetic acid-induced writhing test at the higher dose. Moreover, AEMC significantly reduced the leukocyte migration in doses of 200 and 400 mg/kg and showed mild antibacterial activity. Together, the results suggest that properties of M. citrifolia leaf extract should be explored further in order to achieve newer tools for managing painful and inflammation conditions, including those related to oxidant states.

    In this study the leaves of the Thai noni/Yor, (Morinda citrifolia Linn.) were extracted by several methods and evaluated against human cancer cell lines: KB (human epidermoid carcinoma), HeLa (human cervical carcinoma), MCF-7 (human breast carcinoma) and HepG2 (human hepatocellular carcinoma) cell lines as well as a Vero (African green monkey kidney) cell line, employing the MTT colorimetric method, comparing it to damnacanthal, rutin, and scopoletin. The dichloromethane extract of the fresh leaf showed a better inhibitory effect against KB and HeLa cells with IC50 values of 21.67 and 68.50 microg/ml, respectively. The dichloromethane extract of dried leaves revealed cytotoxicity against the KB cell line with an IC50 value of 39.00 microg/ml. Other extracts, as well as rutin and scopoletin, showed reduced anti-proliferative effects on all cancer cell lines (IC50 103 to over 600 microg/ml). Interestingly, the damnacanthal had potent cytotoxicity against all cancer cell lines and Vero cell lines. These results suggest Thai noni extracts may be safer than the pure compounds, due to their higher safety ratios, which is a good indicator for possible cancer treatment. Several non-aqueous extracts from the leaves showed antioxidant properties, giving IC50 values of 0.20-0.35 mg/ml. It can be concluded the leaves of M. citrifolia may have benefit as a food supplement for chemoprevention against epidermoid and cervical cancers.

    Full Text Available Morinda citrifolia L (noni is an evergreen or small tree that grows in many tropical regions of the world. The use of the noni leaves has not been so studied however; there are reports of its pharmacological benefits. Aims: The objective of this investigation was to assess the genotoxicity, short-term, and subchronic oral toxicity of Morinda citrifolia L leaves aqueous extract. Methods: The genotoxicity of the M. citrifolia extract was investigated by measuring the frequency of micronuclei in mice bone marrow cells. The animals were treated with three doses of the extract (500, 1000, and 2000 mg/kg. For short-term toxicity, both sexes Wistar rats received 1000 mg/kg/day for 28 days. Animals were sacrificed for hematological and biochemical evaluation. For the subchronic study, Wistar rats were administered with three doses of M. citrifolia extract (100, 300, and 1000 mg/kg by oral route for 90 days. Mortalities, clinical signs, body weight changes, food and water consumption, hematological and biochemical parameters, gross findings, organ weights, and histological examination were monitored during the study period. Results: Genotoxicity and short-term toxicity test resulted in absence of toxicity at doses between 500 and 2000 mg/kg. Significant differences were observed in hemoglobin, and differential leukocyte count after subchronic dosing of the extract. Histology evaluation did not reveal treatment-related abnormalities. Variations observed were within to normal range and reversible. Conclusions: In summary, 1000 mg/kg orally was the NOAEL for M. citrifolia extract for effects other than transient variations in some hematological parameters within normal range.

    Lung cancer causes 1.4 million deaths annually. In the search for functional foods as complementary therapies against lung cancer, the immuno-stimulatory properties of the vegetable Morinda citrifolia leaves were investigated and compared with the anti-cancer drug erlotinib. Lung tumour-induced BALB/c mice were fed with 150 mg kg(-1) or 300 mg kg(-1) body weight of the leaf extract, or erlotinib (50 mg kg(-1) body-weight) for 21 days. The 300 mg kg(-1) body weight extract significantly (and dose-dependently) suppressed lung tumour growth; the extract worked more effectively than the 50 mg kg(-1) body weight erlotinib treatment. The extract significantly increased blood lymphocyte counts, and spleen tissue B cells, T cells and natural killer cells, and reduced the epidermal growth factor receptor (EGFR) which is a lung adenocarcinoma biomarker. The extract also suppressed the cyclooxygenase 2 (COX2) inflammatory markers, and enhanced the tumour suppressor gene (phosphatase and tensin homolog, PTEN). It inhibited tumour growth cellular gene (transformed mouse 3T3 cell double minute 2 (MDM2), V-raf-leukemia viral oncogene 1 (RAF1), and mechanistic target of rapamycin (MTOR)) mRNA expression in the tumours. The extract is rich in scopoletin and epicatechin, which are the main phenolic compounds. The 300 mg kg(-1)Morinda citrifolia leaf 50% ethanolic extract showed promising potential as a complementary therapeutic dietary supplement which was more effective than the 50 mg kg(-1) erlotinib in suppressing lung adenocarcinoma. Part of the mechanisms involved enhancing immune responses, suppressing proliferation and interfering with various tumour growth signalling pathways.

    Full Text Available Background: Morinda citrifolia (Rubiaceae, commonly known as noni is distributed throughout tropical and sub-tropical regions of the world. Anti-allergic effects of noni have not been reported despite the clinical usage as an anti-allergic agent. Materials and Methods: To investigate the anti-allergic effects of the 50% ethanolic extract of M. citrifolia fruits and leaves (MCF-ext and MCL-ext, dinitrofluorobenzene (DNFB-induced triphasic cutaneous reaction and picryl chloride-induced contact dermatitis (PC-CD tests were performed. Results: In DNFB-induced triphasic cutaneous reaction, oral administration of MCF-ext and MCL-ext exhibited dose-dependent inhibition of cutaneous reaction at 1 h (immediate phase response after the DNFB challenge. MCF-ext also inhibited ear swelling at 24 h (late phase response and 8 days (very late phase response after the DNFB challenge. The effect of MCL-ext on the immediate phase response was attributed to the anti-degranulation from RBL-2H3 cells, while MCF-ext had no significant effect on degranulation. The active components of anti-degranulation activity in MCL-ext were determined to be ursolic acid, rutin and kaempferol-3-O-α-L-rhamnopyranosyl-(1→6-β-D-glucopyranoside. In the PC-CD test, both MCF-ext and MCL-ext showed an anti-swelling effect but the potency of MCF-ext was stronger than MCL-ext. Conclusion: These data suggest that noni fruits and leaves can be a daily consumable material for the prevention of allergic symptoms.

    Full Text Available Morinda citrifolia L. (noni is one of the most important traditional Polynesian medicinal plants. The primary indigenous use of this plant appears to be of the leaves, as a topical treatment for wound healing. The ethanol extract of noni leaves (150 mg kg−1 day−1 was used to evaluate the wound-healing activity on rats, using excision and dead space wound models. Animals were randomly divided into two groups of six for each model. Test group animals in each model were treated with the ethanol extract of noni orally by mixing in drinking water and the control group animals were maintained with plain drinking water. Healing was assessed by the rate of wound contraction, time until complete epithelialization, granulation tissue weight and hydoxyproline content. On day 11, the extract-treated animals exhibited 71% reduction in the wound area when compared with controls which exhibited 57%. The granulation tissue weight and hydroxyproline content in the dead space wounds were also increased significantly in noni-treated animals compared with controls (P < 0.002. Enhanced wound contraction, decreased epithelialization time, increased hydroxyproline content and histological characteristics suggest that noni leaf extract may have therapeutic benefits in wound healing.

    Morinda citrifolia (Indian mulberry or noni) fruit has been long used as a folk medicine for a wide range of health purposes as it is claimed to have analgesic, antiinflammatory, antioxidant, detoxifier, and cell-rejuvenator properties. A recent study has revealed central nervous system suppressant nature of its extract. Hence, the present study has evaluated the anxiolytic, sedative, and hypnotic effects of the aqueous extracts of Morinda citrifolia in rodents in comparison to diazepam. Anxiety was assessed by 'Isolation-induced aggression' model, sedation by 'Spontaneous locomotor activity using actophotometer' and hypnotic activity by 'Prolongation of ketamine-induced sleeping time'. Six male mice were used for each of the groups and postdose, all the six that received diazepam had shown an inhibition of aggression, whereas in the test group, five of six mice and none in the control group had shown an inhibition of aggression (P = 0.0007). Similarly, for the sedative activity, the total number of spontaneous locomotor activity at 30 min following drug administration was found to be 364.67 ± 10.74, 123.16 ± 8.33, and 196.67 ± 3.7, while at 60 min it was found to be 209 ± 12.98, 49 ± 5.78, and 92 ± 2.5 (mean ± SD) for the control, standard, and test groups of mice respectively (P < 0.001). Hypnotic activity was measured by prolongation of ketamine-induced sleeping time wherein the onset and duration of loss of righting reflex were compared among each group of mice. The time in minutes for the onset in control, standard, and test groups was 4.01 ± 0.22, 1.23 ± 0.05, and 2.23 ± 0.07, respectively. The duration of loss of righting reflex was 44.23 ± 0.59, 56.03 ± 1.34, and 50.57 ± 0.36, respectively. Both these were statistically significant (P < 0.001). However, more clinical studies are needed to assess the long-term effects of the extract in humans.

    Morinda citrifolia L. (NONI) fruits have been used for thousands of years for the treatment of many health problems including cancer, cold, diabetes, flu, hypertension, and pain. Plant extracts have reported several therapeutic benefits, but extraction of individual compound from the extract often exhibits limited clinical utility as the synergistic effect of various natural ingredients gets lost. They generally constitute polyphenols and flavonoids. Studies have suggested that these phytochemicals, especially polyphenols, display high antioxidant properties, which help to reduce the risk of degenerative diseases, such as cancer and cardiovascular diseases. Several in-vitro and in-vivo studies have shown that Noni fruits have antioxidant, anti-inflammatory, anti-dementia, liver-protective, anticancer, analgesic, and immunomodulatory effects. Till date about 7 in vitro cancer studies have been done, but a detailed in vitro study including cell cycle and caspase activation assay on breast cancer cell line has not been done. In the present study different Noni fruit fractions have tested on cancer cell lines MCF-7, MDA-MB-231 (breast adenocarcinoma) and one non-cancer cell line HEK-293 (Human embryonic kidney). Out of which ethylacetate extract showed a higher order of in vitro anticancer activity profile. The ethylacetate extract strongly inhibited the proliferation of MCF-7, MDA-MB-231 and HEK-293 cell lines with IC50 values of 25, 35, 60 µg/ml respectively. The extract showed increase in apoptotic cells in MCF-7 and MDA-MB-231 cells and arrested the cell cycle in the G1/S phase in MCF-7 and G0/G1 phase in MDA-MB-231 cells. Noni extract also decreases the intracellular ROS generation and mitochondrial membrane potential.

    The composition of Morinda citrifolia (M. citrifolia) was determined using high-performance liquid chromatography (HPLC), and the anticancer effects of M. citrifolia extract evaluated in HepG2, Huh7, and MDA-MB-231 cancer cells. M. citrifolia fruit extracts were obtained by using five different organic solvents, including hexane (Hex), methanol (MeOH), ethyl acetate (EtOAc), chloroform (CHCl3), and ethanol (EtOH). The water-EtOAc extracts from M. citrifolia fruits was found to have the highest anticancer activity. HPLC data revealed the predominance of chrysin in water-EtOAc extracts of M. citrifolia fruit. Furthermore, the combined effects of cotreatment with apigenin and chrysin on liver and breast cancer were investigated. Treatment with apigenin plus chrysin for 72-96 h reduced HepG2 and MDA-MB-231 cell viability and induced apoptosis through down-regulation of S-phase kinase-associated protein-2 (Skp2) and low-density lipoprotein receptor-related protein 6 (LRP6) expression. However, the combination treatment for 36 h synergistically decreased MDA-MB-231 cell motility but not cell viability through down-regulation of MMP2, MMP9, fibronectin, and snail in MDA-MB-231 cells. Additionally, chrysin combined with apigenin also suppressed tumor growth in human MDA-MB-231 breast cancer cells xenograft through down-regulation of ki-67 and Skp2 protein. The experimental results showed that chrysin combined with apigenin can reduce HepG2 and MDA-MB-231 proliferation and cell motility and induce apoptosis. It also offers opportunities for exploring new drug targets, and further investigations are underway in this regard.

    Intestinal microflora and inflammation are associated with the risk of inflammatory bowel diseases. Noni (Morinda citrifolia L.) has various bioactivities, but its effect on colon health remains unknown. This study focused on the effects of fermented noni fruit extracts on colon microflora and inflammation of colon epithelial cells. The anti-inflammatory activities of ethanol and ethyl acetate extracts on Caco-2 cells were evaluated including interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2). The growth of Lactobacillus and Bifidobacterium species was promoted by ethanol extract. Ethyl acetate extract decreased intracellular reactive oxygen species and significantly suppressed COX-2, IL-8, and prostaglandin E2 production and neutrophil chemotaxis by suppressing the translocation of the p65 subunit. Quercetin was the main contributor to the anti-inflammatory activity. The fermented noni fruit promoted probiotic growths and downregulated the intracellular oxidation and inflammation in Caco-2 cells. These results suggest that fermented noni fruit might protect against inflammatory diseases of the colon.

    Morinda citrifolia leaf extract was tested for larvicidal activity against three medically important mosquito vectors such as malarial vector Anopheles stephensi, dengue vector Aedes aegypti, and filarial vector Culex quinquefasciatus. The plant material was shade dried at room temperature and powdered coarsely. From the leaf, 1-kg powder was macerated with 3.0 L of hexane, chloroform, acetone, methanol, and water sequentially for a period of 72 h each and filtered. The yield of extracts was hexane (13.56 g), chloroform (15.21 g), acetone (12.85 g), methanol (14.76 g), and water (12.92 g), respectively. The extracts were concentrated at reduced temperature on a rotary vacuum evaporator and stored at a temperature of 4°C. The M. citrifolia leaf extract at 200, 300, 400, 500, and 600 ppm caused a significant mortality of three mosquito species. Hexane, chloroform, acetone, and water caused moderate considerable mortality; however, the highest larval mortality was methanolic extract, observed in three mosquito vectors. The larval mortality was observed after 24-h exposure. No mortality was observed in the control. The third larvae of Anopheles stephensi had values of LC(50) = 345.10, 324.26, 299.97, 261.96, and 284.59 ppm and LC(90) = 653.00, 626.58, 571.89, 505.06, and 549.51 ppm, respectively. The Aedes aegypti had values of LC(50) = 361.75, 343.22, 315.40, 277.92, and 306.98 ppm and LC(90) = 687.39, 659.02, 611.35, 568.18, and 613.25 ppm, respectively. The Culex quinquefasciatus had values of LC(50) = 382.96, 369.85, 344.34, 330.42, and 324.64 ppm and LC(90) = 726.18, 706.57, 669.28, 619.63, and 644.47 ppm, respectively. The results of the leaf extract of M. citrifolia are promising as good larvicidal activity against the mosquito vector Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus.

    Morinda citrifolia L. commonly known as noni is used by the pharmaceutical and cosmetic industries due to the plethora of pharmacological activities of its metabolites. In Mauritius, the fruits of M. citrifolia are used in folk medicine against a number of indications. The present study aimed at evaluating the antioxidant activity of ripe and unripe noni fruit at both biochemical and cellular levels. Using an array of established assay systems, the fruit antioxidant propensity was assessed in terms of its radical scavenging, iron reducing and metal chelating potentials. Ascorbic acid, total phenolic and total flavonoid contents of the fruits were also determined. The ascorbic acid content of ripe noni was 76.24 ± 1.13 mg/100 g while total phenolics of ripe and unripe fruit extracts were 748.40 ± 8.85 μg and 770.34 ± 2.27 μg GAE g(-1) FW respectively. Both the ripe and unripe extracts of M. citrifolia were potent scavengers of nitric oxide, superoxide and hydroxyl radicals. The ferric reducing capacity ranged from 11.26 ± 0.33 to 11.90 ± 0.20 mM Fe(2+) g(-1) FW while the IC50 values for the iron (II) chelating power were 0.50 ± 0.01 and 1.74 ± 0.01 g FW/mL for the ripe and unripe fruit extracts respectively. Cellular studies additionally demonstrated that noni were able to dose-dependently counteract accumulation of reactive oxygen species (ROS)-induced oxidative stress, a potential obesogenic factor within human liposarcoma SW872 cells as well as significantly restore cell death within the concentration range of 0.106-0.813 g/mL. Results reported herein suggest noni as an interesting source of prophylactic antioxidants modulated by its polyphenol composition.

    Full Text Available Use of alternative medicine to control oral streptococci is a new topic worthy of further investigation. This study aimed to elucidate the dose-dependent anti-bacterial activity of crude aqueous extract of ripe Morinda citrifolia L. (Family: Rubiaceae fruits against oral streptococci i.e. Streptococcus mutans and Streptococcus mitis, that cause dental caries in humans.Fresh ripe M. citrifolia fruits (750g were ground in an electronic blender with sterile water (500ml. The crude aqueous extract was lyophilized to yield a brown colored powder. Various concentrations (1000-100μg/ ml of the extract were tested for its antibacterial activity (Kirby and Bauer method against whole cells of S. mutans and S. mitis. Minimum Inhibitory Concentration (MIC was determined by micro-dilution method, using serially diluted (2 folds fruit extract, according to the National Committee for Clinical Laboratory Standards (NCCLS.Crude aqueous extract (1000μg/ ml of ripe M. citrifolia fruits effectively inhibited the growth of S. mutans (19±0.5 mm and S. mitis (18.6±0.3 mm compared to the streptomycin control (21.6±0.3 mm. The growth inhibition was clearly evident with "nil" bacteriostasis, even after 48 hours of incubation at 37°C. The MIC of the extract for S. mutans and S. mitis was 125 μg and 62.5 μg, respectively.Our results suggest that phytochemicals naturally synthesized by M. citrifolia have an inhibitory effect on oral streptococci. Furthermore, purification and molecular characterization of the "bioactive principle" would enable us to formulate a sustainable oral hygiene product.

    The development of complementary and/or alternative drugs for treatment of hepatitis C virus (HCV) infection is still needed. Antiviral compounds in medicinal plants are potentially good targets to study. Morinda citrifolia is a common plant distributed widely in Indo-Pacific region; its fruits and leaves are food sources and are also used as a treatment in traditional medicine. In this study, using a HCV cell culture system, it was demonstrated that a methanol extract, its n-hexane, and ethyl acetate fractions from M. citrifolia leaves possess anti-HCV activities with 50%-inhibitory concentrations (IC(50)) of 20.6, 6.1, and 6.6 μg/mL, respectively. Bioactivity-guided purification and structural analysis led to isolation and identification of pheophorbide a, the major catabolite of chlorophyll a, as an anti-HCV compound present in the extracts (IC(50) = 0.3 μg/mL). It was also found that pyropheophorbide a possesses anti-HCV activity (IC(50) = 0.2 μg/mL). The 50%-cytotoxic concentrations (CC(50)) of pheophorbide a and pyropheophorbide a were 10.0 and 7.2 μg/mL, respectively, their selectivity indexes being 33 and 36, respectively. On the other hand, chlorophyll a, sodium copper chlorophyllin, and pheophytin a barely, or only marginally, exhibited anti-HCV activities. Time-of-addition analysis revealed that pheophorbide a and pyropheophorbide a act at both entry and the post-entry steps. The present results suggest that pheophorbide a and its related compounds would be good candidates for seed compounds for developing antivirals against HCV.

    Phytotherapy is an emerging field successfully utilized to treat various chronic diseases including alcohol dependence. In the present study, we examined the effect of the standardized methanolic extract of Morinda citrifolia Linn. unripe fruit (MMC), on compulsive ethanol-seeking behavior using the mouse conditioned place preference (CPP) test. CPP was established by injections of ethanol (2 g/kg, i.p.) in a 12-day conditioning schedule in mice. The effect of MMC and the reference drug, acamprosate (ACAM), on the reinforcing properties of ethanol in mice was studied by the oral administration of MMC (1, 3, and 5 g/kg) and ACAM (300 mg/kg) 60 min prior to the final CPP test postconditioning. Furthermore, CPPs weakened with repeated testing in the absence of ethanol over the next 12 days (extinction), during which the treatment groups received MMC (1, 3, and 5 g/kg, p.o.) or ACAM (300 mg/kg, p.o.). Finally, a priming injection of a low dose of ethanol (0.4 g/kg, i.p.) in the home cage (Reinstatement) was sufficient to reinstate CPPs, an effect that was challenged by the administration of MMC or ACAM. MMC (3 and 5 g/kg, p.o.) and ACAM (300 mg/kg, p.o.) significantly reversed the establishment of ethanol-induced CPPs and effectively facilitated the extinction of ethanol CPP. In light of these findings, it has been suggested that M. citrifolia unripe fruit could be utilized for novel drug development to combat alcohol dependence.

    Helicobacter pylori is a human gastric pathogen that adheres to host cells and injects cytotoxin-associated gene A (CagA) to induce interleukin-8 (IL-8), inducible nitric oxide (iNOS), and cyclooxygenase 2 (COX-2). Noni (Morinda citrifolia) is found to possess antibacteria, anti-inflammation, and antioxidation activities, but its effect on H. pylori infection is still unknown. Ethanol and ethyl acetate extracts of noni fruit were used in this study. The inhibitory effect on CagA and H. pylori-induced IL-8, iNOS, and COX-2 were determined. The coculture medium was collected for measuring neutrophil chemotaxis. Both extracts of noni fruit showed weak inhibition on H. pylori. Both ethanol and ethyl acetate extracts provided antiadhesion of H. pylori to AGS cells and down-regulation on the CagA, IL-8, COX-2, and iNOS expressions. Results also indicated both extracts relieved neutrophil chemotaxis. Noni fruit extracts down-regulated inflammatory responses during H. pylori infection, and the phenolic compounds play key role in antiadhesion.

    The objective of this study was to examine the effects of Morinda citrifolia (noni) extract and its constituents on α-melanocyte stimulating hormone (α-MSH)-stimulated melanogenesis in cultured murine B16 melanoma cells (B16 cells). A 50% ethanolic extract of noni seeds (MCS-ext) showed significant inhibition of melanogenesis with no effect on cell proliferation. MCS-ext was more active than noni leaf and fruit flesh extracts. Activity guided fractionation of MCS-ext led to the isolation of two lignans, 3,3'-bisdemethylpinoresinol (1) and americanin A (2), as active constituents. To elucidate the mechanism of melanogenesis inhibition by the lignans, α-MSH-stimulated B16 cells were treated with 1 (5 μM) and 2 (200 μM). Time-dependent increases of intracellular melanin content and tyrosinase activity, during 24 to 72 h, were inhibited significantly by treatment with the lignans. The activity of 1 was greater than that of 2. Western blot analysis suggested that the lignans inhibited melanogenesis by down regulation of the levels of phosphorylation of p38 mitogen-activated protein kinase, resulting in suppression of tyrosinase expression.

    The objective of this study was to examine whether a 50% ethanolic extract (MCS-ext) of the seeds of Morinda citrifolia (noni) and its constituents have matrix metalloproteinase-1 (MMP-1) inhibitory activity in UVA-irradiated normal human dermal fibroblasts (NHDFs). The MCS-ext (10 μg/mL) inhibited MMP-1 secretion from UVA-irradiated NHDFs, without cytotoxic effects, at 48 h after UV exposure. The ethyl acetate-soluble fraction of MCS-ext was the most potent inhibitor of MMP-1 secretion. Among the constituents of the fraction, a lignan, 3,3'-bisdemethylpinoresinol (1), inhibited the MMP-1 secretion at a concentration of 0.3 μM without cytotoxic effects. Furthermore, 1 (0.3 μM) reduced the level of intracellular MMP-1 expression. Other constituents, namely americanin A (2), quercetin (3) and ursolic acid (4), were inactive. To elucidate inhibition mechanisms of MMP-1 expression and secretion, the effect of 1 on mitogen-activated protein kinases (MAPKs) phosphorylation was examined. Western blot analysis revealed that 1 (0.3 μM) reduced the phosphorylations of p38 and c-Jun-N-terminal kinase (JNK). These results suggested that 1 suppresses intracellular MMP-1 expression, and consequent secretion from UVA-irradiated NHDFs, by down-regulation of MAPKs phosphorylation.

    In this thesis we design new cryptographic protocols, whose security is based on the hardness of root extracting or more speci cally the RSA problem. First we study the problem of root extraction in nite Abelian groups, where the group order is unknown. This is a natural generalization of the...... construction based on root extracting. As an example of this, we modify Cramer-Shoup signature scheme such that it becomes a genericm algorithm. We discuss then implementing it in RSA groups without the original restriction that the modulus must be a product of safe primes. It can also be implemented in class......,  providing a currently acceptable level of security. This allows us to propose the rst practical blind signature scheme provably secure, without relying on heuristics called random oracle model (ROM). We obtain the protocol for issuing blind signatures by implementing our modi ed Fischlin's signing algorithm...

    The prevalence of obesity is increasing worldwide, with high fat diet (HFD) as one of the main contributing factors. Obesity increases the predisposition to other diseases such as diabetes through various metabolic pathways. Limited availability of antiobesity drugs and the popularity of complementary medicine have encouraged research in finding phytochemical strategies to this multifaceted disease. HFD induced obese Sprague-Dawley rats were treated with an extract of Morinda citrifolia L. leaves (MLE 60). After 9 weeks of treatment, positive effects were observed on adiposity, fecal fat content, plasma lipids, and insulin and leptin levels. The inducement of obesity and treatment with MLE 60 on metabolic alterations were then further elucidated using a (1)H NMR based metabolomics approach. Discriminating metabolites involved were products of various metabolic pathways, including glucose metabolism and TCA cycle (lactate, 2-oxoglutarate, citrate, succinate, pyruvate, and acetate), amino acid metabolism (alanine, 2-hydroxybutyrate), choline metabolism (betaine), creatinine metabolism (creatinine), and gut microbiome metabolism (hippurate, phenylacetylglycine, dimethylamine, and trigonelline). Treatment with MLE 60 resulted in significant improvement in the metabolic perturbations caused obesity as demonstrated by the proximity of the treated group to the normal group in the OPLS-DA score plot and the change in trajectory movement of the diseased group towards the healthy group upon treatment.

    The present study was designed to investigate the effect of a methanolic extract of Morinda citrifolia Linn. fruit (MMC) on the rewarding effect of heroin in the rat conditioned place preference (CPP) paradigm and naloxone-precipitated withdrawal in mice. In the first experiment, following a baseline preference test (preconditioning score), the rats were subjected to conditioning trials with five counterbalanced escalating doses of heroin versus saline followed by a preference test conducted under drug-free conditions (post-conditioning score) using the CPP test. Meanwhile, in the second experiment, withdrawal jumping was precipitated by naloxone administration after heroin dependence was induced by escalating doses for 6 days (3×/ day). The CPP test results revealed that acute administration of MMC (1, 3, and 5 g/kg body weight (bw), p.o.), 1 h prior to the CPP test on the 12th day significantly reversed the heroin-seeking behavior in a dose-dependent manner, which was similar to the results observed with a reference drug, methadone (3 mg/kg bw, p.o.). On the other hand, MMC (0.5, 1, and 3 g/kg bw, p.o.) did not attenuate the heroin withdrawal jumps precipitated by naloxone. These findings suggest that the mechanism by which MMC inhibits the rewarding effect of heroin is distinct from naloxone-precipitated heroin withdrawal.

Standard root extract of Anacyclus pyrethrum (AP root extract showed an increase in ambulatory behaviour indicating a stimulant effect of the photoactometer. AP root extract produces a significant antidepressant effect in both FST and TST as they reduced the immobility. AP root extract was found to be effective in reversing hypothermia produced by clonidine and reserpine. In our study, we found that AP root extract inhibited haloperidol-induced catalepsy. These study suggest that AP root extract might produce antidepressant effect by interaction with adrenergic and dopamine receptor thereby increasing the level of noradrenaline and dopamine in brains of mice.

    The search for new treatments against leishmaniasis has increased due to high frequency of drug resistance registered in endemics areas, side effects, and complications caused by coinfection with HIV. Morinda citrifolia Linn., commonly known as Noni, has a rich chemical composition and various therapeutic effects have been described in the literature. Studies have shown the leishmanicidal activity of M. citrifolia; however, its action on the parasite has not yet been elucidated. In this work, we analyzed leishmanicidal activity and ultrastructural changes in Leishmania infantum promastigotes caused by M. citrifolia fruit juice treatment. M. citrifolia fruit extract showed a yield of 6.31% and high performance liquid chromatography identified phenolic and aromatic compounds as the major constituents. IC50 values were 260.5 µg/mL for promastigotes and 201.3 µg/mL for intracellular amastigotes of L. infantum treated with M. citrifolia. Cytotoxicity assay with J774.G8 macrophages showed that M. citrifolia fruit juice was not toxic up to 2 mg/mL. Transmission electron microscopy showed cytoplasmic vacuolization, lipid inclusion, increased exocytosis activity, and autophagosome-like vesicles in L. infantum promastigotes treated with M. citrifolia fruit juice. M. citrifolia fruit juice was active against L. infantum in the in vitro model used here causing ultrastructural changes and has a future potential for treatment against leishmaniasis. PMID:27313649

    2015-06-01

    Full Text Available Antimicrobial activity of Abitulon indicum roots was studied against seven pathogenic bacteria and three fungal strains by agar well diffusion method. Antimicrobial activity was recorded for hexane, chloroform, methanol, ethanol and aqueous extracts. Alcohol (ethanol and methanol extracts exhibited the highest degree of antimicrobial activity compared to aqueous, chloroform and hexane extracts. Pseudomonas aeruginosa was turned out to be the most susceptible bacterium to the crude root chemical constituents, using the standard Tetracycline and Clotrimazole. Minimum inhibition concentration values of hexane, chloroform, methanol, ethanol and aqueous extracts were determined by the agar dilution method and ranged between 62.5 and 1,000 µg. The study suggested that the root extracts possess bioactive compounds with antimicrobial activity against the tested bacteria and fungi, revealing a significant scope to develop a novel broad spectrum of antimicrobial drug formulation from Abitulon indicum.

    This review investigated the relationship of noni juice, or its extract (fruit, leaves or root), to anticancer and/or immunostimulant properties. A Medline search was conducted using the key search words 'Morinda citrifolia' and 'Morinda citrifolia and cancer' (1964 to October, 2011) along with cross-referencing. Botanical and chemical indexes were not included. A total of 304 and 29 (10%) articles, respectively, were found under these key terms. Of the 19 studies actually related to cancer, seven publications were in vitro cancer studies, nine were in vivo animal cancer studies, and three were in vivo human cancer studies. Among the in vitro studies, a 'concentrated component' in noni juice and not pure noni juice may (1) stimulate the immune system to 'possibly' assist the body fight the cancer, and (2) kill a small percentage (0-36%) of cancer cells depending on the type. The nine animal studies suggest that a concentrated component in noni juice may stimulate the immune system; but only slightly increases the number (about 1/3; 25-45%) of surviving mice. Other than two case studies, only two human clinical studies existed. The first consisted of testing freeze-dried noni fruit, which reduced pain perception, but did not reverse advanced cancer. The second was on smokers ingesting an unknown concentration of noni juice who experienced decreased aromatic DNA adducts, and decreased levels of plasma superoxide anion radicals and lipid hydroperoxide. Factors to consider in the future are clearly defining the substance being tested, and whether or not the juice is pasteurized. Some reports of hepatotoxicity exist, although there were confounding factors in most of the case reports. More importantly, noni juice is high in potassium and needs to be monitored by patients with kidney, liver or heart problems. In conclusion, a few in vitro and in vivo animal studies suggest a possible unidentified substance in unpasteurized noni fruit juice that may have a small degree of

    Clinicians have many treatment techniques from which to choose when extracting a failing tooth and replacing it with an implant-supported restoration and when successful management of an extraction socket during the course of tooth replacement is necessary to achieve predictable and esthetic outcomes. This article presents a straightforward, yet thorough, classification for extraction sockets of single-rooted teeth and provides guidance to clinicians in the selection of appropriate and predictable treatment. The presented classification of extraction sockets for single-rooted teeth focuses on the topography of the extraction socket, while the protocol for treatment of each socket type factors in the shape of the remaining bone, the biotype, and the location of the socket whether it be in the mandible or maxilla. This system is based on the biologic foundations of wound healing and can help guide clinicians to successful treatment outcomes.

    The extraction process of Sphallerocarpus gracilis root polysaccharides (SGRP) was optimized using response surface methodology with two methods [hot-water extraction (HWE) and ultrasonic-assisted extraction (UAE)]. The antioxidant activities of SGRP were determined, and the structural features of the untreated materials (HWE residue and UAE residue) and the extracted polysaccharides were compared by scanning electron microscopy. Results showed that the optimal UAE conditions were extraction temperature of 81°C, extraction time of 1.7h, liquid-solid ratio of 17ml/g, ultrasonic power of 300W and three extraction cycles. The optimal HWE conditions were 93°C extraction temperature, 3.6h extraction time, 21ml/g liquid-solid ratio and three extraction cycles. UAE offered a higher extraction yield with a shorter time, lower temperature and a lower solvent consumption compared with HWE, and the extracted polysaccharides possessed a higher antioxidant capacity. Therefore, UAE could be used as an alternative to conventional HWE for SGRP extraction.

    Ricinus communis Linn (Euphorbiaceae) plant parts are claimed to be used as carminative, asthma, bronchitis, leprosy, anti-inflammatory, cathartic, and aphrodisiac. The toxicological study was carried out in the root part of the plant. The collected root was extracted with methanol and water. The extracts were vacuum-dried to yield the respective aqueous (AE) and methanol (ME) extracts. Toxicological assessment sought to determine the safety of Ricinus communis root extracts. The extracts were evaluated in the acute toxicity study (OECD-423 guidelines) and 90 days repeated dose toxicological assessment in Wistar albino rats. The acute oral toxicity of the aqueous (AE) and methanol (ME) extracts did not produce any toxic symptoms or mortality at the dose level of 2000 mg/kg in rats. In the 90 days (sub-chronic toxicity) repeated dose toxicity study the extracts (AE and ME) were administered 1000 mg/kg daily through oral route. The sub-chronic toxicity study demonstrated no significant changes in body weight, food, and water intake. Hematology parameters RBC, WBC, DLC, Hb, blood clotting time, and the biochemical parameters glucose, blood urea nitrogen, creatinine, total cholesterol, total protein, total bilirubin AST, ALT, and ALP were estimated. Histopathology observation of the major vital organs (liver, kidney, heart, spleen, lungs, ovary, testis, and brain) were tested. The hematology, biochemical and histopathology evaluations did not show any adverse effects in any of the organs tested. These results demonstrate the non-toxic nature of the root extracts AE and ME can be used for long-term usage in clinical practice.

    A large number of compounds have been reported in peanut plants. Many of these compounds are phytoalexins, which are produced by plants experiencing environmental stress and often exhibit antioxidant activity. It is difficult to determine which of the many compounds has the greatest impact on total antioxidant capacity in a mixture. The objectives of this research were to examine the oxygen-radical absorbing capacity (ORAC) value and total phenolic contents of peanut root extracts and peanut root extract fractions collected via HPLC. Peanut roots were extracted from four different cultivars (Brantley, NC-12, Phillips, and Wilson) with 70% aqueous ethanol with ultrasonic assistance. Each cultivar was sampled in duplicate. The extracts were fractionated into 18 3-min fractions by HPLC using a C-18 column. Fractions and crude extracts were freeze dried. ORAC values and total phenolic content were then determined for all fractions and crude extracts. Fractions had a significant effect on the μM TE/mg gallic acid equivalents (GAE). ORAC values ranged from -46.89 μM TE to 185 μM TE in HPLC fractions. ORAChromatography can be used to focus on antioxidants in complex samples.

    Full Text Available The present study was carried out to evaluate the cerebroprotective effect of the aqueous extract of the roots of Glycyrrhiza glabra Linn. (250 and 500 mg/kg in hypoxic rats. Hypoxia was induced by providing sodium nitrite drinking water to rats for 14 days. Extract at the tested doses promoted the locomotor activity and spatial behavior significantly, which was impaired in hypoxic rats. The extract administration restored the decreased levels of brain enzymes such as glutamate and dopamine and decreased acetylcholinesterase (AchE activity significantly. Levels of antioxidant enzymes such as superoxide dismutase, glutathione peroxidase, glutathione reductase and catalase were reduced due to hypoxia and were restored to near normalcy by administration of ethanol extract of G. glabra. Increased lipid peroxidation in hypoxic rats was also restored significantly by extract treatment. Thus, this study suggests that ethanol extract of G. glabra possess a cerebroprotective effect in hypoxic rats, which may be mediated by its antioxidant effects.

    Objective: To investigate the phytochemical screening (group determination) and selected pharmacological activities (antioxidant, antimicrobial and analgesic activity) of the plant Sida cordifolia Linn (S. cordifolia). Methods: Eighty percent concentrated ethanol extract of the roots was used. To identify the chemical constituents of plant extract standard procedures were followed. In phytochemical screening the crude extract was tested for the presence of different chemical groups like reducing sugar, tannins, saponins, steroids, flavonoids, gums, alkaloids and glycosides. The antioxidant property of ethanolic extract of S. cordifolia was assessed by DPPH free radical scavenging activity. Analgesic activity of the extract was tested using the model of acetic acid induced writhing in mice. Diclofenac sodium is used as reference standard drug for the analgesic activity test. Antibacterial activity of plant extract was carried out using disc diffusion method with five pathogenic bacteria comparison with kanamycin as a standard. Results:Phytochemical analysis of the ethanolic extract of the roots of S. cordifolia indicated the presence of reducing sugar, alkaloids, steroids and saponins. In DPPH scavenging assay the IC50 value was found to be 50 µg/mL which was not comparable to the standard ascorbic acid. The crude extract produced 44.30%inhibition of writhing at the dose of 500 mg/kg body weight which is statistically significant (P>0.001). The in vitro antimicrobial activity of the ethanol extract of the roots of S. cordifolia showed no antimicrobial activity against five types of microorganisms. The experiment was conducted only with five species of bacteria as test species, which do not at all indicate the total inactivity against micro-organisms. Conclusions: The obtained results provide a support for the use of this plant in traditional medicine but further pharmacological studies are required.

    Withania somnifera extracts are known for their anti-cancerous, anti-inflammatory and antioxidative properties. One of their mechanisms of actions is to modulate mitochondrial function through increasing oxidative stress. Recently ‘priming’ has been suggested as a potential mechanism for enhancing cancer cell death. In this study we demonstrate that ‘priming’, in HT-29 colon cells, with W. somnifera root extract increased the potency of the chemotherapeutic agent cisplatin. We have also showed the W. somnifera root extract enhanced mitochondrial dysfunction and that the underlying mechanism of ‘priming’ was selectively through increased ROS. Moreover, we showed that this effect was not seen in non-cancerous cells. PMID:28129345

    Full Text Available Abstract Solanum paniculatum L., Solanaceae, locally known as "jurubeba", is widely used in Brazil for culinary purposes, and in folk medicine to treat of diverse disorder including gastric dysfunctions. In this study we investigated the antidiarrheal activity of S. paniculatum roots extract in rats at different concentrations (125, 250 and 500 mg/kg, p.o using different experimental models such as castor oil-induced diarrhea, enteropooling and gastrointestinal motility, determined by in vivo experimental models. The major compound of root extract was characterized as chlorogenic acid based in the IR, 1D and 2D NMR analysis. All the extract doses achieved antidiarrheal potency, as indicated by reduced weight of feces in castor oil-induced diarrhea, decreased intestinal motility and significantly inhibited castor oil-induced enteropooling compared to the vehicle group. The highest dose (500 mg/kg produced greater anti-motility effect and better reduction of enteropooling, similar to the reference drug Loperamide (5 mg/kg. Extract from S. paniculatum L. roots had antidiarrheal activity, as shown by the lower weight of the feces as well as decrease in the accumulation of intestinal fluid and slower transit, justifying the traditional use of plant for diarrhea.

    Morinda citrifolia Linn (Rubiaceae) is a traditional medicinal herb that has been purported to be beneficial in the treatment of infections due to its immune enhancing properties. However, detailed studies highlighting the effect of different compounds isolated from the plant on the immune system are lacking. In this study, the stimulatory effects of the extracts and fractions of M. citrifolia fruits on important components of the adaptive immune system such as T lymphocytes and B lymphocytes were studied. The effects of the plant extracts on lymphocytes were assessed by in vitro (MTT assay) and in vivo (cell mediated immune response) techniques. Results of the MTT study indicated that the hydroalcoholic (0.5 and 1.0 mg/mL) and aqueous extracts (0.5 and 1.0 mg/mL) significantly (p citrifolia fruits on B-cells was measured by the delayed type hypersensitivity method. The study revealed that the hydroalcoholic extract (200 mg/kg) and fraction F I (40 mg/kg) significantly increased the humoral response to the extent of 33.33 and 35.12%, respectively. The results of this study confirm the cellular and humoral immunostimulant properties of M. citrifolia fruits and justify its usage in traditional medicine.

    Efficacy of Morinda citrifolia L. leaf (MLE) and fruit extracts (MFE) in inhibiting lipoprotein lipase (LPL) was determined in vitro. The result of the study showed that the highest inhibition on the LPL activity was exhibited by MLE (66%+/- 2.1%), which is significantly higher than that demonstrated by MFE (54.5%+/- 2.5%), green tea extract (GTE) (54.5%+/- 2.6%), and catechin (43.6%+/- 6.1%). Percent of LPL inhibition increase with concentration of the extracts. Quantitative analysis of the extracts revealed the presence of high levels of (+)-catechin at 63.5 +/- 17 and 53.7 +/- 5.7 mg/g in MLE and MFE, respectively, although not as high as that found in GTE (530.6 +/- 42 mg/g). Appreciable amount of epicatechin was found in all extracts tested, while rutin was only found in MLE and MFE. The study suggested that both leaf and fruit of M. citrifolia may be used as antiobesity agents in body weight management.

    Introduction: Endodontic infections are polymicrobial in nature. Candida albicans is the most common fungus isolated from failed endodontic cases. The constant increase in antibiotic resistant strains and side-effects caused by synthetic drugs has prompted researchers to look for herbal alternatives such as propolis, Morinda citrifolia and Azadirachta indica (Neem) etc., since, the gold standard for irrigation, i.e., sodium hypochlorite has many disadvantages. Materials and Methods: Extracted human mandibular premolars were biomechanically prepared, vertically sectioned, placed in tissue culture wells exposing the root canal surface to C. albicans grown on Sabouraud Dextrose Agar to form a biofilm. At the end of 2 days, all groups were treated with test solutions and control for 10 min and evaluated for Candida growth and number of colony forming units. The readings were subjected to statistical analysis using analysis of variance and post hoc Tukey tests. Results: Sodium hypochlorite and propolis groups exhibited highest antimicrobial efficacy against C. albicans with no statistically significant difference. It was followed by the A. indica (Neem) group. M. citrifolia had limited antifungal action followed by the negative control group of saline. Conclusion: According to the results of this study, propolis can be used as an effective antifungal agent similar to that of sodium hypochlorite, although long-term in vivo studies are warranted.

Materials and Methods: Extracted human mandibular premolars were biomechanically prepared, vertically sectioned, placed in tissue culture wells exposing the root canal surface to C. albicans grown on Sabouraud Dextrose Agar to form a biofilm. At the end of 2 days, all groups were treated with test solutions and control for 10 min and evaluated for Candida growth and number of colony forming units. The readings were subjected to statistical analysis using analysis of variance and post hoc Tukey tests. Results: Sodium hypochlorite and propolis groups exhibited highest antimicrobial efficacy against C. albicans with no statistically significant difference. It was followed by the A. indica (Neem group. M. citrifolia had limited antifungal action followed by the negative control group of saline. Conclusion: According to the results of this study, propolis can be used as an effective antifungal agent similar to that of sodium hypochlorite, although long-term in vivo studies are warranted.

    Antidiabetic effects of Morinda citrifolia (aka Noni) fermented by Cheonggukjang (fast-fermented soybean paste) were evaluated using a T2DM (type 2 diabetes mellitus) murine model. Six-week-old KK-Ay/TaJcl mice were randomly divided into four groups: (1) the diabetic control (DC) group, provided with a normal mouse diet; (2) the positive control (PC) group, provided with a functional health food diet; (3) the M. citrifolia (MC) group, provided with an MC-based diet; (4) the fermented M. citrifolia (FMC) group, provided with an FMC-based diet. Over a testing period of 90 days, food and water intake decreased significantly in the FMC and PC groups compared with the DC group. Blood glucose levels in the FMC group were 211.60-252.20 mg/dL after 90 days, while those in the control group were over 400 mg/dL after 20 days. In addition, FMC supplementation reduced glycosylated hemoglobin (HbA1c) levels, enhanced insulin sensitivity, and significantly decreased serum triglycerides and low-density lipoprotein (LDL) cholesterol. Furthermore, a fermented M. citrifolia 70% ethanolic extract (FMCE) activated peroxisome proliferator-activated receptor-(PPAR-) γ and stimulated glucose uptake via stimulation of AMP-activated protein kinase (AMPK) in cultured C2C12 cells. These results suggest that FMC can be employed as a functional health food for T2DM management.

    Free radicals induce numerous diseases by lipid peroxidation and DNA damage. It has been reported that some of the extracts from plants possess antioxidant properties capable of scavenging free radicals in vivo. Vetiveria zizanioides belonging to the family Gramineae, is a densely tufted grass which is widely used as a traditional plant for aromatherapy, to relieve stress, anxiety, nervous tension and insomnia. In this regard, the roots of V zizanioides was extracted with ethanol and used for the evaluation of various in vitro antioxidant activities such as reducing power ability, superoxide anion radical scavenging activity, deoxyribose degradation assay, total antioxidant capacity, total phenolics and total flavonoid composition. The various antioxidant activities were compared with suitable antioxidants such as butyl hydroxy toluene, ascorbic acid, quercetin, alpha tocopherol, pyrocatechol and curcumin respectively. The generation of free radicals O2, H2O2 OH and N O were effectively scavenged by the ethanolic extract of V zizanioides. In all these methods, the extract showed strong antioxidant activity in a dose dependent manner. The results obtained in the present study clearly indicates that V zizanioides scavenges free radicals, ameliorating damage imposed by oxidative stress in different disease conditions and serve as a potential source of natural antioxidant. The study provides a proof for the ethnomedical claims and reported biological activities. The plant has, therefore, very good therapeutic and antioxidant potential.

    Full Text Available In India, more than 300 million people use Devanagari script for documentation. In Devanagari script, Marathi and Hindi are mainly used as primary language of Maharashtra state and national language of India respectively. As compared with English script, Devanagari script is reach of morphemes. Thus the lemmatization of Devanagari script is quite complex than that of English script. There is lack of resources for Devanagari script such as WordNet, ontology representation, parsing the keywords and their part of speech. Thus the overall task of information retrieval becomes complex and time consuming. Devanagari script document always carries suffixes which may cause problem in accurate information retrieval. We propose a method of extracting root words from Devanagari script document which can be used for information retrieval, text summarization, text categorization, ontology building etc. An attempt is made to design the Morphological Analyzer for Devanagari script. We have designed CORPUS containing more than 3000 possible stop words and suffixes for Marathi language. Morphological Analyzer can acts as a preliminary stage for developing any information retrieval application in Devanagari script. We have conducted the experiments on randomly selected Marathi documents and we found the accuracy of designed morphological analyzer is up to 96%.

    Full Text Available We propose a robust formant extraction algorithm that combines the spectral peak picking, formants location examining for peak merger checking, and the root extraction methods. The spectral peak picking method is employed to locate the formant candidates, and the root extraction is used for solving the peak merger problem. The location and the distance between the extracted formants are also utilized to efficiently find out suspected peak mergers. The proposed algorithm does not require much computation, and is shown to be superior to previous formant extraction algorithms through extensive tests using TIMIT speech database.

    In the present study, we report a green methodology for the synthesis of silver and gold nanoparticles, using the root extract of the herbal medicinal plant Korean red ginseng. The silver and gold nanoparticles were synthesized within 1 h and 10 min respectively. The nanoparticles generated were not aggregated, and remained stable for a long time, which suggests the nature of nanoparticles. The phytochemicals and ginsenosides present in the root extract assist in reducing and stabilizing the synthesized nanoparticles. The red ginseng root extract-generated silver nanoparticles exhibit antimicrobial activity against pathogenic microorganisms including Vibrio parahaemolyticus, Staphylococcus aureus, Bacillus cereus, and Candida albicans. In addition, the silver nanoparticles exhibit biofilm degrading activity against S. aureus and Pseudomonas aeruginosa. Thus, the present study opens up a new possibility of synthesizing silver and gold nanoparticles in a green and rapid manner using Korean red ginseng root extract, and explores their biomedical applications.

    Full Text Available Herb-drug interaction studies have getting attention recently due to the increasingly use of herbal products worldwide. The porpose of the present study was to examine the in vitro effect of methanol leaf extract of Orthosiphon stamineus and Morinda citrofolia fruit juice extract on hepatic aminopyrine metabolism by CYP 3A in different age of normal and STZ-induced diabetic Sprague Dawley (SD rats. Isolated rat hepatocytes were prepared using the collagenase perfusion technique. Aminopyrine was used as a probe substrate to determine the hepatic levels of CYP 3A by measuring the activity of N-demethylation of aminopyrine in rat hepatocytes according to the method described by Nash. Results obtained showed that aminopyrine N-demethylase activity measured from all diabetic rat hepatocytes was not affected by 0. stamineus and M. citrifolia extract. A significant decrease in the aminopyrine N-demethylase activity was observed in the normal old male SD rat hepatocytes preincubated with 0.1 mg/kg (P< 0.01 of methanol extract of 0. stamineus when compared to the respective control group. M. citrifolia juice extract at 0.1 mg/ml (P< 0.01 significantly increased aminopyrine N-demethylase activity in normal adult male SD rat hepatocytes as compared to the control group. For conclusion, both M. citrifolia and 0. stamineus extract could affect the in vitro metabolism of aminopyrine by CYP3A in normal rat hepatocytes. No significant change in the hepatic aminopyrine metabolism was observed in the diabetic rats after incubating with different concentrations of M. citrifolia and 0. stamineus extracts. The observed herb-drug interactions in the present study was age- and disease-dependent.

    Nymphaea hybrid, a water lily from the Nymphaeaceae family, has been found to exhibit some in vivo beneficial effects. In the present study we investigated the lifespan-extending effects of Nymphaea hybrid root extract in the nematode Caenorhabditis elegans. We found that Nymphaea hybrid root extract significantly extended the lifespan of C.elegans and improved its locomotion during aging. Moreover, Nymphaea hybrid root extract increased the resistance of C.elegans to both heat stress and oxidative stress. We found that the ability of Nymphaea hybrid root extract to increase lifespan was independent of its antimicrobial effects and was probably associated with its effects on the reproduction of C.elegans. In addition, the lifespan-extending effects of Nymphaea hybrid root extract were found to be dependent on the insulin/IGF signaling pathway. We also found that total flavones of Nymphaea hybrid could increase survival of C.elegans in both normal and adverse conditions, indicating that total flavones comprise the major fractions with lifespan-extending effects. Therefore, Nymphaea hybrid root extract has lifespan-extending effects in C.elegans and could be developed as a functional food.

    Full Text Available Abstract Background Arctium lappa, known as burdock, is widely used in popular medicine for hypertension, gout, hepatitis and other inflammatory disorders. Pharmacological studies indicated that burdock roots have hepatoprotective, anti-inflammatory, free radical scavenging and antiproliferative activities. The aim of this study was to evaluate total phenolic content, radical scavenging activity by DPPH and in vitro antiproliferative activity of different A. lappa root extracts. Methods Hot and room temperature dichloromethanic, ethanolic and aqueous extracts; hydroethanolic and total aqueous extract of A. lappa roots were investigated regarding radical scavenging activity by DPPH, total phenolic content by Folin-Ciocalteau method and antiproliferative in vitro activity was evaluated in human cancer cell lines. The hydroethanolic extract analyzed by high-resolution electrospray ionization mass spectroscopy. Results Higher radical scavenging activity was found for the hydroethanolic extract. The higher phenolic contents were found for the dichloromethane, obtained both by Soxhlet and maceration extraction and hydroethanolic extracts. The HRESI-MS demonstrated the presence of arctigenin, quercetin, chlorogenic acid and caffeic acid compounds, which were identified by comparison with previous data. The dichloromethane extracts were the only extracts that exhibited activity against cancer cell lines, especially for K562, MCF-7 and 786-0 cell lines. Conclusions The hydroethanolic extracts exhibited the strongest free radical scavenging activity, while the highest phenolic content was observed in Soxhlet extraction. Moreover, the dichloromethanic extracts showed selective antiproliferative activity against K562, MCF-7 and 786-0 human cancer cell lines.

    Full Text Available Dependence of efficiency of fructans extraction on soaking time, temperature and time of high temperature extraction was investigated. Dried and powdered chicory Cichorium intybus L. cv Pala rossa «hairy» roots obtained by Agrobacterium rhizogenes-mediated transformation with pCB161 vector were used for study. There were used low- and high-temperature extractions without heating at +22 °C during 0.5; 1 and 24 hours and with heating at +70 °C, +80 °C and +90 °C during 10, 20 and 30 minutes. Fructans fractionation was conducted by two ways: separation of high molecular weight fraction by crystallization at +4 °C and low molecular weight separation by extraction with 95% ethanol. To determine fructans concentration in the extracts McRary and Slattery method was used. Based on the experimental data, a mathematical model of fructan extraction process was created. Its adequacy was tested with the Fisher criterion and coefficient of determination. Optimal parameters of the extraction process chosen using the methods of linear programming were determined. Extraction for 30 minutes at 90 °C without soaking identified as the most tech nological one. It allowed to extract fructans general amount from transgenic roots (146 ±8,77 mg/g of root dry weight. Optimal regime of fructan obtaining from chicory «hairy» roots is extraction at +90 °C for 30 min. Preliminary soaking time does not affect any effectiveness for such extraction. The most effective mode of obtaining of low- and high molecular fractions of fructans from transgenic chicory roots is twostage extraction with 95% ethanol at +80 °C and water at +90 °C with the duration of each stage of 30 minutes.

    The objective of this work was to fit together the starch extraction from Pachyrhizus ahipa roots and the recovery of the proteins present in these storage organs, making an improved use of this novel raw material. The replacement of water by buffer PO4(-3)/NaCl as solvent in the first extraction steps improved protein extraction without lowering the starch yield. The starches obtained from the traditional and the proposed methods exhibited some differences in appearance and technological and thermal properties, which were endorsed to the adjustment in the methodology of extraction rather than to the use of buffer as solvent. Thus, P. ahipa starch obtaining procedure could be coupled to protein extraction with a minimum change in the methodology. This innovation did not significantly shift the characteristics of the starch obtained and allowed to obtain a protein yield of 135.7mg BSA equivalent protein/100g of fresh roots.

    Free radicals have been implicated in many diseases. They attack biological macromolecules in healthy human cells and cause protein and DNA damage along with lipid peroxidation. Present study reports the phytochemical analysis as well as free radical scavenging and antioxidant activities of Solanum xanthocarpum root extracts. Tannins, flavonoids, terpenoids, alkaloids, saponins and steroids were present in different extracts. Total flavonoid content in extracts was quantified and maximum contents were found in ethyl acetate fraction followed by chloroform and ethyl alcohol fractions, respectively. Dose dependent response was observed in metal ion chelating activity of extracts. Comparatively better chelating activity was found in polar extracts. Most of the extracts exhibited significant free radical scavenging activity in DPPH radical scavenging assay. Ethanolic and aqueous extracts accounted for about 40—50% lipid peroxidation inhibition (LPOI) in rat liver homogenate. Antioxidant activity did not show direct correlation with the amount of flavonoid contents in the extracts. However, direct correlation was observed between DPPH free radical scavenging activity and LPOI. Antioxidant activity of the extracts was compared with standard antioxidants. The differential activity observed in extracts could be attributed to the presence of other phytochemicals such as tannins and terpenoids in addition to flavonoids. The study demonstrated appreciable protective efficacy in S. xanthocarpum root extracts against free radical damage.

    This in vitro study sought to evaluate the effectiveness of castor oil extract used as an irrigating solution on Escherichia coli and its endotoxins in root canals. Sixty single-rooted teeth were prepared (using castor oil extract as irrigating solution) and divided into five groups (n = 12): Group 1 samples were treated with calcium hydroxide (Ca(OH)2), Group 2 samples were treated with polymyxin B, Group 3 samples were treated with Ca(OH)2 and 2% chlorhexidine gel (CHX), and Group 4 samples were treated with castor oil extract. A control group used physiological saline solution as an irrigant. Canal content samples were collected at four different times: immediately after instrumentation, seven days after instrumentation, after 14 days of intracanal medication, and seven days after removal of intracanal medication. A plating method was used to assess antimicrobial activity and the quantification of endotoxins was evaluated by the chromogenic Limulus lysate assay. Data were submitted to ANOVA and a Dunn test (a = 5%). Irrigation with castor oil extract decreased E. coli counts but had no effect on the level of endotoxins. Samples taken seven days after removal of medication revealed a significant reduction in endotoxin levels in Groups 3 and 4. Compared to the saline solution irrigation, castor oil extract decreased microorganism counts in root canals immediately after canal preparation. None of the medications used completely eliminated endotoxins in the root canal.

    2012-04-01

    Full Text Available INTRODUCTION: Apical root resorption is a frequent and occasionally critical problem in orthodontic patients undergoing induced tooth movement. One of the factors that might influence prognosis, especially in maxillary incisors, which most frequently present resorptions, are the so-called the anatomical barriers; that is, proximity of the buccal and palatal cortical bones to the maxillary incisor roots. OBJECTIVE: The purpose of this research was to investigate whether patients with excessive vertical growth really present a small distance between the alveolar cortical bones and the maxillary incisor roots, and whether there is a correlation between this distance and the root resorption index in comparison with patients presenting horizontal growth. METHODS: The sample comprised orthodontic records of 18 patients with extraction planning of first maxillary premolars and treatment by the standard and/or preadjusted edgewise brackets. Their initial and final periapical radiographs were evaluated to determine the amount of root resorption that occurred. RESULTS: On the palatal side, patients with excessive vertical growth (Group 2 - SN-GoGn > 43º showed a narrower alveolar bone than the horizontal growth patients (Group 1 - SN-GoGn < 29º. However, the distance between the buccal cortical bone and the central incisor root apex showed no significant difference between Groups 1 and 2; CONCLUSIONS: It was concluded that there are no correlations between the proximity of buccal cortical bone, maxillary incisor roots and the root resorption index.

    Full Text Available Euphorbia thymifolia root is having the protective effect against female reproductive dysfunctions. This study is to evaluate the antioxidant activity of ethanolic extract of Euphorbia thymifolia root in treating stress induced female reproductive dysfunctions. Forced swimming stress (15min/day for 28 days and restraint stress (3h/day for 28 days were the methods employed to induce female reproductive dysfunction in rats. Ethanolic extract of Euphorbia thymifolia root was given to rats in two doses, 100 mg/kg and 200 mg/kg for 28 days along with induction of stress and its effectiveness was assessed by observing changes in SOD, catalase and lipid peroxidation of uterus and ovary. The results were analyzed by using one-way ANOVA followed by Dunnett’s test. Euphorbia thymifolia root extract showed a significant antioxidant activity which is evident by increase in the levels of SOD and catalase, decrease in the levels of lipid peroxidation confirming the antioxidant effect which was found to be dose dependent. The antioxidant activity may be due to the presence of various phytochemical constituents like alkaloids, flavonoids and other constituents present in the Euphorbia thymifolia root.

    With the advent of high-throughput platforms, proteomics has become a powerful tool to search for plant gene products of agronomic relevance. Protein extractions using multistep protocols have been shown to be effective to achieve better proteome profiles than simple, single-step extractions. These protocols are generally efficient for above ground tissues such as leaves. However, each step leads to loss of some amount of proteins. Additionally, compounds such as proteases in the plant tissues lead to protein degradation. While protease inhibitor cocktails are available, these alone do not seem to suffice when roots are included in the plant sample. This is obvious given the lack of high molecular weight (HMW) proteins obtained from samples that include root tissue. For protein/proteome analysis of transgenic plant roots or of seedlings, which include root tissue, such pronounced protein degradation is especially undesirable. A facile protein extraction protocol is presented, which ensures that despite the inclusion of root tissues there is minimal loss in total protein components.

    Full Text Available Background: The genus Amaranthus has potential activity as a hepatoprotective agent. Objective : The present pharmacological investigation focuses on evaluation of the efficacy of aqueous extract of roots of Amaranthus tricolor Linn. for their protection against paracetamol (PCM overdose induced hepatotoxicity . Materials and Methods: The aqueous extract of roots of A. tricolor Linn. was prepared and phytochemical screening was done. The biochemical investigation viz. serum glutamic oxaloacetate transaminase (SGOT, serum glutamic pyruvate transaminase (SGPT, alkaline phosphatase (ALP and total Bilirubin (TB was done against PCM-induced hepatotoxicity in wistar albino rats. The histopathological studies of liver were also done. Results: The phytochemical screening of the aqueous extract showed the presence of alkaloids, carbohydrates, flavanoids, amino acids, proteins, fixed oil, saponins and tannins, and phenolic compounds. Pretreatment with the aqueous extract of root significantly prevented the physical, biochemical, histological, and functional changes induced by paracetamol in the liver. The extract showed significant hepatoprotective effects as evidenced by decreased serum enzyme activities like SGPT, SGOT, ALP, and TB, which was supported by histopathological studies of liver. The aqueous extract showed significant hepatoprotective activity comparable with standard drug silymarin as well as hepatotoxin drug PCM. Conclusion: From these results, it is concluded that the A. tricolor has potential effectiveness in treating liver damage in a dose dependent manner.

    Full Text Available The purpose of the present study was to investigate the antioxidant activity and fructans content in ethanol and water extracts of roots of elecampane (Inula helenium L., a Bulgarian medicinal plant. The extraction procedure included 95% (v/v ethanol extraction and subsequent water treatment. The antioxidant activity was evaluated by several reliable methods such as DPPH-, ABTS-, FRAP- and CUPRAC-assays, as well as the total phenolic content. In addition, the total fructans and sugar content were determinated by spectrophotomeric, TLC and HPLC-RID methods. The level of fructans in ethanol extracts was 14.1 g / 100 g dry weight, as nystose and 1-kestose were only 0.3 g / 100 g dry weight, and 0.5 g / 100g dry weight, respectively. The absence of fructooligosacharides and sugars in water extracts after the ethanol pretreatment was established. Inulin content was evaluated to be 32 g / 100 g dry weight. The metabolites profile of roots revealed their potential application as radical scavengers due to the presence of polyphenols. Therefore, the root extracts of elecampane could be assumed as a rich source of biologically active substance, in particular dietary fiber with potential prebiotic effect, due to the presence of polysaccharide inulin and fructooligosacharides.

    In Ayurveda, Withania somnifera is commonly known as Ashwagandha, its roots are specifically used in medicinal and clinical applications. It possesses numerous therapeutic actions which include anti-inflammatory, sedative, hypnotic and narcotic. Extracts from this plant have been reported for its anticancer properties. In this study we evaluated for the first time, the cytotoxic effect of Withania root extract on human malignant melanoma A375 cells. The crude extract of Withania was tested for cytotoxicity against A375 cells by MTT assay. Cell morphology of treated A375 cells was visualized through phase contrast as well as fluorescence microscopy. Agarose gel electrophoresis was used to check DNA fragmentation of the crude extract treated cells. Crude extract of Withania root has the potency to reduce viable cell count in dose as well as time dependent manner. Morphological change of the A375 cells was also observed in treated groups in comparison to untreated or vehicle treated control. Apoptotic body and nuclear blebbing were observed in DAPI stained treated cells under fluorescence microscope. A ladder of fragmented DNA was noticed in treated cells. Thus it might be said that the crude water extract of Withania somnifera has potent cytotoxic effect on human malignant melanoma A375 cells.

    Full Text Available Adipose tissue dysfunction constitutes a primary defect in obesity and might link this disease to severe chronic health problems. We aimed to evaluate the antioxidant activity of three extracts from Taraxacum officinale (dandelion as well as their effects on mature 3T3-L1 adipocytes concerning intracellular lipid accumulation and cytotoxicity, this would give indications regarding therapeutic interest of dandelion as potential anti-obesity candidate. Antioxidant activities of extracts from dandelion roots and leaves were evaluated in vitro using 1,1-diphenyl-2-picrylhyorazyl (DPPH and Ferric Reducing Antioxidant Power (FRAP methods at the concentration range used in cellular assays (300–600 µg/mL. The influence of the extracts on mature 3T3-L1 adipocyte viability was determined by the 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assay. Lipid content was determined by Oil-red-O staining. The extracts showed effective antioxidant activity correlating with total flavonoid and polyphenol contents. However, the functionality level was weakly associated with the antioxidant activity. Further, our data demonstrated that mature 3T3-L1 adipocytes reduced in size and number when incubated with the extracts, which suggests a significant increase in lipolysis activity. Particularly, leaf extract and crude powdered root of dandelion reduced triglyceride accumulation in mature 3T3-L1 adipocytes to a greater extent that the extract from the root. Our study shows anti-lipogenic effects of dandelion extracts on adipocytes as well as radical scavenging and reducing activity. Importantly, along with previous results indicating that cell populations cultivated in the presence of the dandelion extracts decrease in 3T3-L1 adipogenesis capacity, these results suggests that these extracts might represent a treatment option for obesity-related diseases by affecting different processes during the adipocyte life cycle.

    Rapidly increasing aging population and environmental stressors are the two main global concerns of the modern society. These have brought in light rapidly increasing incidence of a variety of pathological conditions including brain tumors, neurodegenerative & neuropsychiatric disorders, and new challenges for their treatment. The overlapping symptoms, complex etiology and lack of full understanding of the brain structure and function to-date further complicate these tasks. On the other hand, several herbal reagents with a long history of their use have been asserted to possess neurodifferentiation, neuroregenerative and neuroprotective potentials, and hence been recommended as supplement to enhance and maintain brain health and function. Although they have been claimed to function by holistic approach resulting in maintaining body homeostasis and brain health, there are not enough laboratory studies in support to these and mechanism(s) of such beneficial activities remain largely undefined. One such herb is Ashwagandha, also called "Queen of Ayurveda" for its popular use in Indian traditional home medicine because of its extensive benefits including anticancer, anti-stress and remedial potential for aging and neurodegenerative pathologies. However, active principles and underlying mechanism(s) of action remain largely unknown. Here we provide a review on the effects of Ashwagandha extracts and active principles, and underlying molecular mechanism(s) for brain pathologies. We highlight our findings on the nootropic potential of Ashwagandha leaves. The effects of Ashwagandha leaf extracts are multidimensional ranging from differentiation of neuroblastoma and glioma cells, reversal of Alzheimer and Parkinson's pathologies, protection against environmental neurotoxins and enhancement of memory.

    Pfaffia glomerata (Amaranthaceae) is popularly known as "Brazilian ginseng." Previous studies have shown that fructose is the major carbohydrate component present in its roots. Inulin-type fructans, polymers of fructose, are the most widespread and researched prebiotics. Here, we isolated and chemically characterized inulin extracted from P. glomerata roots and investigated its potential prebiotic effect. Fructans were isolated and their structures were determined using colorimetric, chromatography, polarimetry, and spectroscopic analysis. The degree of polymerization (DP) was determined, and an in vitro prebiotic test was performed. The structure of inulin was confirmed by chromatography and spectroscopic analysis and through comparison with existing data. Representatives from the genera Lactobacillus and Bifidobacterium utilized inulin from P. glomerata, because growth was significantly stimulated, while this ability is strain specific. The results indicated that inulin extracted from P. glomerata roots represents a promising new source of inulin-type prebiotics.

    Objective:To search systematically for an alternative therapy with compounds particularly from plant origin.Methods: Efficacy test of different root extracts ofWithania somnifera (W. somnifera) (L) Dunalagainst multi drug resistant(MDR)Staphylococcus aureus(S. aureus)variants was performed following the agar well diffusion method. Evaluation of susceptibility pattern of the isolates was carried out by employing disk diffusion method using standard antibiotic disks. Results:In vitro study withW. somniferaroot extracts was found to be effective against all the MDRS. aureusstrains isolated from local and patient sources. Different root extracts of WS showed different degree of effectiveness against the isolates.Conclusions: The major active principles responsible for the antibacterial efficacy were mainly present in methanol(MeOH) extract and ethanol (EtOH)extracts as well as in butanol (BuOH) extract fraction. Amongst all the extracts the BuOH fraction was found to be most active against all the isolates but aqueous extract was the least active one. Finally it may be concluded that the antimicrobials fromW. somnifera may raise an alternative therapy forMDR staphylococcal infections in near future.

The current study evaluated the effect of aqueous extracts from seven botanical species applied to 40, 50, 60, 70 and 80 days after sowing 'Nantes' carrots in soil infested with root-knot nematode. Three other treatments included cassava wastewater, distilled water (control, which were applied in the same periods of the extracts application, in addition to carbofuran 50G (80Kg/ha, which was applied once at 60 days after carrot sowing. Evaluations were performed at 90 days after inoculation to determine shoot and root fresh weight, as well as the diameter and the length of principal roots and the number of galls on primary and secondary roots. Plants treated with cassava wastewater, extracts of Ricinus communis L. seeds, Crotalaria juncea L. seeds, R. communis leaves + branches + fruits, Chenopodium ambrosioides L. leaves + branches + inflorescences and Azadirachta indica A. Juss. seeds showed the highest rates of total weight (root + shoot and shoot weight. The extract of R. communis leaves + branches + fruits provides the highest total root weight and principal root diameter. Cassava wastewater and extracts of R. communis seeds provided the highest principal root weight. The extract of R. communis seeds and cassava wastewater can be considered promising for the alternative control of M. incognita.

    Full Text Available Abstract Background Ternimalia brownii Fresen (Combretaceae is widely used in traditional medicine to treat bacterial, fungal and viral infections. There is a need to evaluate extracts of this plant in order to provide scientific proof for it's wide application in traditional medicine system. Methods Extraction of stem bark, wood and whole roots of T. brownii using solvents of increasing polarity, namely, Pet ether, dichloromethane, dichloromethane: methanol (1:1, methanol and aqua, respectively, afforded dry extracts. The extracts were tested for antifungal and antibacterial activity and for brine shrimp toxicity test. Results Extracts of the stem bark, wood and whole roots of T. brownii exhibited antibacterial activity against standard strains of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhi, and Bacillus anthracis and the fungi, Candida albicans and Cryptococcus neoformans. Aqueous extracts exhibited the strongest activity against both bacteria and fungi. Extracts of the roots and stem bark exhibited relatively mild cytotoxic activity against brine shrimp larvae with LC50 values ranging from 113.75–4356.76 and 36.12–1458.81 μg/ml, respectively. The stem wood extracts exhibited the highest toxicity against the shrimps (LC50 values 2.58–14.88 μg/ml, while that of cyclophosphamide, a standard anticancer drug, was 16.33 (10.60–25.15 μg/ml. Conclusion These test results support traditional medicinal use of, especially, aqueous extracts for the treatment of conditions such as diarrhea, and gonorrhea. The brine shrimp results depict the general trend among plants of the genus Terminalia, which are known to contain cytotoxic compounds such as hydrolysable tannins. These results warrant follow-up through bioassay-directed isolation of the active principles.

    Objective:To evaluate the wound healing and antimicrobial activity of root extracts of Ixora coccinea (I. coccinea).Methods: To investigate the wound healing efficacy of root extract of I. coccinea Linn, five groups of animals were divided each containing six animals. Two wound models including incision and excision wound models were used in this study. The parameters studied were tensile strength on incision wound model and in terms of wound contraction for excision wound model were compared with standard Nitrofurazone(NFZ) ointment (0.2% w/w). Six extracts (ethanol, aqueous, petroleum ether, benzene, chloroform and ethyl acetate ) ofI. coccinea were screened forin vitro growth inhibiting activity against different bacterial strainsviz, Staphylococcus aureus, Bacillus pumilius, Enterococcus faecalis, Escherichia coli, Salmonella typhi andPseudomonas aeruginosa and fungi Candida albicans and Aspergillus niger were compared with the standard drugs ciprofloxacin and chloramphenicol for antibacterial and griseofulvin for antifungal screening. The serial dilution and cup (or) well plate methods were used for the antimicrobial study andMIC was determined.Results: The ethanolic extract showed significant (P<0.001) wound healing activity when compared to standard drugNFZ with respect to normal control group. Amongst all, ethanolic extract showed highly significant antibacterial activity against all bacterial strains used in this study when compared to standard. The aqueous extract showed moderate significant inhibition against all bacterial strains when compared to standard. All the extracts were shown negligible activity against the fungal strains used in this study. Conclusions: The ethanolic root extract of I. coccinea showed pronounced wound healing and antibacterial activity. The probable reason to heal the wound was that the external application of the extract prevented the microbes to invade through the wound thus the protection of wound occurs against the

    Full Text Available Cymbidium has known antibacterial and antiedema activity and has been used as an ingredient in cosmetics and fragrances. The effects of Cymbidium ethanol extract (CYM on allergic response and the underlying mechanisms of action have not been reported. Therefore, the purpose of this study was to determine the effect of CYM on allergic responses. Topical application of CYM was effective against immunoglobulin E (IgE/dinitrophenyl-conjugated bovine serum albumin- (DNP-BSA- induced degranulation of RBL-2H3 cells and anaphylaxis in ICR mice. An allergic dermatitis-like mouse model was used to evaluate the therapeutic potential of CYM in vivo. Continuous application of 2,4-dinitrochlorobenzene (DNCB not only induced dermatitis in ICR mice but also aggravated the skin lesioning. However, the application of CYM decreased skin lesion severity, scratching behavior, and IgE levels. In addition, CYM downregulated the expression of the proinflammatory cytokines interleukin- (IL- 4, IL-13, and tumor necrosis factor- (TNF- α. Studies of signal transduction pathways showed that CYM suppressed the phosphorylation of spleen tyrosine kinase (Syk, an upstream molecule. It also inhibited the phosphorylation of Akt, phospholipase C- (PLC- γ, and mitogen-activated protein kinase kinase kinase (MEKK. These results indicate that CYM may be effective in preventing and reducing allergic response and may have therapeutic potential as an antiallergic agent in disorders such as atopic dermatitis.

    Plant extracts have traditionally been used as sources of natural antimicrobial compounds, although in many cases, the compounds responsible for their antimicrobial efficacy have not been identified. In this study, crude and dialysed extracts from dandelion root (Taraxacum officinale) were evaluated for their antimicrobial properties against Gram positive and Gram negative bacterial strains. The methanol hydrophobic crude extract (DRE3) demonstrated the strongest inhibition of microbial growth against Staphylococcus aureus, methicillin-resistant S. aureus and Bacillus cereus strains. Normal phase (NP) fractionation of DRE3 resulted in two fractions (NPF4 and NPF5) with enhanced antimicrobial activity. Further NP fractionation of NPF4 resulted in two fractions (NPF403 and NPF406) with increased antimicrobial activity. Further isolation and characterisation of compounds in NPF406 using liquid chromatography solid phase extraction nuclear magnetic resonance LC-SPE-NMR resulted in the identification of 9-hydroxyoctadecatrienoic acid and 9-hydroxyoctadecadienoic acid, while the phenolic compounds vanillin, coniferaldehyde and p-methoxyphenylglyoxylic acid were also identified respectively. The molecular mass of these compounds was confirmed by LC mass spectroscopy (MS)/MS. In summary, the antimicrobial efficacy of dandelion root extracts demonstrated in this study support the use of dandelion root as a source of natural antimicrobial compounds.

    Full Text Available Objectives : To evaluate the antiobesity effects of the ethanolic extract of Argyreia speciosa roots in rats fed with a cafeteria diet (CD. Materials and Methods : Obesity was induced in albino rats by feeding them a CD daily for 42 days, in addition to a normal diet. Body weight and food intake was measured initially and then every week thereafter. On day 42, the serum biochemical parameters were estimated and the animals were sacrificed with an overdose of ether. The, liver and parametrial adipose tissues were removed and weighed immediately. The liver triglyceride content was estimated. The influence of the extract on the pancreatic lipase activity was also determined by measuring the rate of release of oleic acid from triolein. Results : The body weight at two-to-six weeks and the final parametrial adipose tissue weights were significantly lowered (P < 0.01 and P < 0.05, respectively in rats fed with the CD with Argyreia speciosa extract 500 mg/kg/day as compared to the CD alone. The extract also significantly reduced (P < 0.01 the serum contents of leptin, total cholesterol, low density lipoprotein (LDL, and triglycerides, which were elevated in rats fed with CD alone. In addition, the extract inhibited the induction of fatty liver with the accumulation of hepatic triglycerides. The extract also showed inhibition of pancreatic lipase activity by using triolein as a substrate. Conclusions : The ethanolic extract of Argyreia speciosa roots produces inhibitory effects on cafeteria diet-induced obesity in rats.

    Full Text Available Polygonum multiflorum (PM has been commmonly used as folk medicine for treatment of various conditions, such as early graying of hair in humans. However, there have been limited studies which have evaluated the toxicological and biological effects of PM in vitro as well as in vivo. In this study, PM root extracts in ethyl acetate (PM-E and in distilled water (PM-W were examined for their effects on the development of teratogenic defects/deaths. Additionally, they were evaluated for their effects on melanin formation in human melanocytes and pigmentation in embryos/larvae of wild type strain AB zebrafish (Danio rerio. Our results showed that PM root extracts at concentrations of 40 mg/L and 105 mg/L induced the development of teratogenic defects, including yolk sac edema (or heart edema, hemovascular defects, necrosis and abnormal trunk in zebrafish embryos at 4 days post fertilization; teratogenic indexes (TIs were 1.43 and 0.63 for ethyl acetate extract and distilled water extract, respectively. Our results also demonstrated that PM-W significantly increased the pigmentation level of embryos/larvae and induced melanin formation in human melanocytes. The amount of melanin in PM-W-exposed embryos/larvae was 2.2-fold and 1.71-fold greater than those in the control embryos/larvae and control melanocytes, respectively. Our study also showed that the increased level of pigmentation in PM-W embryos/larvae or melanin biosynthesis in melanocytes were both regulated by activation of tyrosinase. Conclusively, our study suggests that PM root extracts could be used as potential agents for treatment of early hair graying as well as various other diseases related to loss of pigmentation. However, these PM root extracts may also have some negative effects on embryos; therefore it should be careful when using for women during pregnancy. [Biomed Res Ther 2016; 3(9.000: 808-818

    Full Text Available Context: Thrombus formation inside the blood vessels obstructs blood flow through the circulatory system leading hypertension, stroke to the heart, anoxia, and so on. Thrombolytic drugs are widely used for the management of cerebral venous sinus thrombosis patients, but they have certain limitations. Medicinal plants and their components possessing antithrombotic activity have been reported before. However, plants that could be used for thrombolysis has not been reported so far. Aims: This study′s aim was to evaluate the thrombolytic potential of selected plants′ root extracts. Settings and Design: Plants were collected, dried, powdered and extracted by methanol and then fractionated by n-hexane for getting the sample root extracts. Venous blood samples were drawn from 10 healthy volunteers for the purposes of investigation. Subjects and Methods: An in vitro thrombolytic model was used to check the clot lysis potential of four n-hexane soluble roots extracts viz., Acacia nilotica, Justicia adhatoda, Azadirachta indica, and Lagerstroemia speciosa along with streptokinase as a positive control and saline water as a negative control. Statistical Analysis Used: Dunnett t-test analysis was performed using SPSS is a statistical analysis program developed by IBM Corporation, USA. on Windows. Results: Using an in vitro thrombolytic model, A. nilotica, L. speciosa, A. indica, and J. adhatoda at 5 mg extract/ml NaCl solution concentration showed 15.1%, 15.49%, 21.26%, and 19.63% clot lysis activity respectively. The reference streptokinase showed 47.21%, and 24.73% clot lysis for 30,000 IU and 15,000 IU concentrations, respectively whereas 0.9% normal saline showed 5.35% clot lysis. Conclusions: The selected extracts of the plant roots possess marked thrombolytic properties that could lyse blood clots in vitro; however, in vivo clot dissolving properties and active components responsible for clot lysis are yet to be discovered.

    Background: There are various microorganisms related to intra and extra-radicular infections and many of these are involved in persistent infections. Bacterial elimination from the root canal is achieved by means of the mechanical action of instruments and irrigation as well as the antibacterial effects of the irrigating solutions. Enterococcus faecalis can frequently be isolated from root canals in cases of failed root canal treatments. Antimicrobial agents have often been developed and optimized for their activity against endodontic bacteria. An ideal root canal irrigant should be biocompatible, because of its close contact with the periodontal tissues during endodontic treatment. Sodium hypoclorite (NaOCl) is one of the most widely recommended and used endodontic irrigants but it is highly toxic to periapical tissues. Objectives: To analyze the literature on the chemotherapeutic agent and plant extracts studied as root canal irrigants. In particularly, the study is focused on their effect on Enterococcus faecalis. Method: Literature search was performed electronically in PubMed (PubMed Central, MEDLINE) for articles published in English from 1982 to April 2015. The searched keywords were “endodontic irrigants” and “Enterococcus faecalis” and “essential oil” and “plant extracts”. Results: Many of the studied chemotherapeutic agents and plant extracts have shown promising results in vitro. Conclusion: Some of the considered phytotherapic substances, could be a potential alternative to NaOCl for the biomechanical treatment of the endodontic space. PMID:28217184

    Commercial application of compost to prevent plant disease is hindered by variable performance. Here, we describe the use of a growth pouch assay to measure impact of a compost water extract (CWE) on root infection under controlled conditions. Most pea roots (≥95%) inoculated with Fusarium solani or Phoma pinodella spores rapidly develop a single local lesion in the region of elongation. In the presence of CWE, infection of pea roots grown in pouches was reduced by 93 to 100%. CWE used as a drench on pea seedlings grown in sand also resulted in 100% protection but, in a heavy clay soil, infection was reduced by roots. CWE inhibited mycelial growth of both pea- and cucumber-infecting isolates of F. solani in culture but exerted root infection. CWE treatment of pea but not cucumber was associated with retention of a sheath of border cells interspersed with bacteria covering the region of elongation. Growth pouch assays may provide a system to monitor effects of specific compost mixtures on root-rhizosphere interactions, and to identify variables influencing disease control.

    Morinda citrifolia, is a valuable medicinal plant with a wide range of therapeutic properties and extensive transformation study on this plant has yet been known. Present study was conducted to establish a simple and reliable transformation protocol for M. citrifolia utilising Agrobacterium tumefaciens via direct seed exposure. In this study, the seeds were processed by tips clipping and dried and subsequently incubated in inoculation medium. Four different parameters during the incubation such as incubation period, bacterial density, temperature and binary vectors harbouring beta-glucuronidase (GUS) gene (pBI121 and pGSA1131), were tested to examine its effect on transformation efficiency. The leaves from the treated and germinated seedlings were analysed via Polymerase Chain Reaction (PCR), histochemical assay of the GUS gene and reverse transcription-PCR (RT-PCR). Results of the study showed that Agrobacterium strain LBA4404 with optical density of 1.0 and 2 h incubation period were optimum for M. citrifolia transformation. It was found that various co-cultivation temperatures tested and type of vector used did not affect the transformation efficiency. The highest transformation efficiency for M. citrifolia direct seed transformation harbouring pBI121 and pGSA1131 was determined to be 96.8% with 2 h co-cultivation treatment and 80.4% when using bacterial density of 1.0, respectively. The transformation method can be applied for future characterization study of M. citrifolia.

    Full Text Available In Indian traditional medicine, Boerhaavia diffusa (punarnava roots have been widely used for the treatment of dyspepsia, jaundice, enlargement of spleen, abdominal pain and as an anti-stress agent. Pharmacological evaluation of the crude ethanolic extract of B. diffusa roots has been shown to possess antiproliferative and immunomodulatory properties. The extract of B. diffusa was studied for anti-proliferative effects on the growth of HeLa cells and for its effect on cell cycle. Bio-assays of extracts from B. diffusa root showed that a methanol : chloroform fraction (BDF 5 had an antiproliferative effect on HeLa cells. After 48 h of exposure, this fraction at a concentration of 200 μg mL−1 significantly reduced cell proliferation with visible morphological changes in HeLa cells. Cell cycle analysis suggests that antiproliferative effect of BDF 5 could be due to inhibition of DNA synthesis in S-phase of cell cycle in HeLa cells, whereas no significant change in cell cycle was detected in control cells. The fraction BDF 5 caused cell death via apoptosis as evident from DNA fragmentation and caspase-9 activation. Thus the extract has potential to be evaluated in detail to assess the molecular mechanism-mediated anticancer activities of this plant.

    Recently, green reduction of graphene oxide (GRO) using various natural materials, including plant extracts, has drawn significant attention among the scientific community. These methods are sustainable, low cost, and are more environmentally friendly than other standard methods of reduction. Herein, we report a facile and eco-friendly method for the bioreduction of GRO using Salvadora persica L. ( S. persica L.) roots (miswak) extract as a bioreductant. The as-prepared highly reduced graphene oxide (SP-HRG) was characterized using powder X-ray diffraction (XRD), ultraviolet-visible (UV-vis) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray photoelectron (XPS) spectroscopy, and transmission electron microscopy (TEM). Various results have confirmed that the biomolecules present in the root extract of miswak not only act as a bioreductant but also functionalize the surface of SP-HRG by acting as a capping ligand to stabilize it in water and other solvents. The dispersion quality of SP-HRG in deionized water was investigated in detail by preparing different samples of SP-HRG with increasing concentration of root extract. Furthermore, the dispersibility of SP-HRG was also compared with chemically reduced graphene oxide (CRG). The developed eco-friendly method for the reduction of GRO could provide a better substitute for a large-scale production of dispersant-free graphene and graphene-based materials for various applications in both technological and biological fields such as electronics, nanomedicine, and bionic materials.

    Full Text Available Cytotoxic and genotoxic effects of methanolic extract of the roots of Strobilanthes heyneanus Nees have been studied on the root meristem cells of Allium cepa. Roots of A. cepa were exposed to different concentrations (0.01%, 0.05%, 0.1% and 0.5% of the extract for ½, 1, 2 and 3 h. Mitotic index and chromosomal aberrations in the treated cells were analysed. Distilled water has been used as control. Mitotic index val¬ues were decreased with increasing concentrations and longer treatment durations compared to the control (p < 0.05 in dose and time dependent manner. Additionally, different abnormal mitotic figures were observed in all treatments. Among these abnormalities were nuclear and chromosome lesions, anaphase bridges, C-mitosis, pulverization, stathmo-anaphases, diagonal orientation, chromosome fragments etc. The total percentage of aberrations generally increased with increasing concentrations of the extract and longer durations of exposure. The observations of the present study are a clear indication of clastogenic and non-clastogenic property of the extract, which is evident from the direct actions on the chromosomes and manifestation of spindle abnormalities.

    It has been known that Arak, Salvadora persica, has a number of medicinal properties. We tried to investigate in vitro scolicidal effect of root extracts of this plant against protoscolices from hydatid cysts of Echinococcus granulosus. Protoscolices were aseptically collected from sheep livers containing hydatid cysts. S. persica root extract was used in 10, 30, and 50 mg/ml concentration for 10, 20, and 30 min. The viability of protoscolices was ascertained by 0.1% eosin staining. Scolicidal activity of S. persica extract at a concentration of 10 mg/ml was 36.3%, 50.3%, and 70.8% after 10, 20, and 30 min of exposure, respectively. The scolicidal effect of this extract at a concentration of 30 mg/ml was 52.9%, 86.7%, and 100% after 10, 20, and 30 min of exposure, respectively. S. persica extract at a concentration of 50 mg/ml, meanwhile, killed 81.4%, 100%, and 100% of protoscolices after 10, 20, and 30 min, respectively. Also, the cytotoxic potential of S. persica was assessed on human liver cells (HepG2) using trypan blue exclusion test. No cytotoxic effect was observed on HepG2 cell line. The present study confirmed for the first time that the ethanolic extract of S. persica has high scolicidal power in vitro. However, in vivo effect of this material remains to be studied for treatment of echinococcosis in humans and herbivorous animals.

    Full Text Available Background. Medicinal plants offer cheaper and safer treatment options to current diabetic drugs. The present study evaluated the effect of aqueous root bark extract of Zanthoxylum chalybeum on oral glucose tolerance and pancreas histopathology in alloxanized rats. Method. Diabetes was induced in rats by administration of alloxan monohydrate. Root extract of Z. chalybeum was administered to rats at 200 and 400 mg/kg BW daily for 28 days. Blood glucose was measured by glucometer and pancreatic histopathology evaluated microscopically. Results. Initial increase was observed in blood glucose of the rats after oral administration of glucose from time zero. Two hours after treatment with Z. chalybeum, a significant reduction in blood glucose was observed within treatment groups (p<0.05 compared to 0.5 hr and 1 hr. There was no significant difference between treatment group receiving 400mg/Kg BW extract and the normal groups (p=0.27, implying that the former group recovered and were able to regulate their blood sugar, possibly via uptake of glucose into cells. The reversal in pancreatic histopathology further supports the protective effect of Z. chalybeum extract towards diabetic damage. Conclusion. Extract of Z. chalybeum is effective in controlling blood glucose in diabetes and protecting pancreatic tissues from diabetic damage.

    Full Text Available Antioxidant activity of some extracts of javanese ginseng root was investigated. Javanese ginseng root extracts were prepared by solvent extraction using methanol, ethanol (96%, ethanol (70%, acetone, and hexane. Total antioxidant activity of the extracts was measured by ferric thiocyanate method, whereas radical scavenging capacity and reducing power were measured by the 1,1-diphenyl-2-picrylhydrazyl and the reducing potential methods, respectively. The result showed that the highest total antioxidant activity was observed in acetone and methanol extracts. It was supposed that the ability of these extracts for partitioning at the interface of the emulsion in the tested oxidation system was the highest among other extracts, therefore it had the best activity to inhibit oxidation. The highest radical scavenging capacity measured by EC50 was observed in acetone extract. The type of phenolic compounds of this extract was suggested to be responsible for the highest radical scavenging capacity. Different phenomena occurred for reducing power. Methanol extract had the highest reducing power and the least is hexane and acetone extract. It was suggested that each extracts comprised different types of phenolic based on different polarity of solvents used for extraction. The antioxidant compounds of javanese ginseng root extracts were primary antioxidant based on these ability to scavenge free radical. It could be concluded that acetone was the best solvent for antioxidant extraction of javanese ginseng root. However, all tested antioxidant mechanisms in this research showed that vitamin E (1000 ppm had better activity than javanese ginseng root extracts (1000 ppm for all types of solvent. Javanese ginseng extracts might contain other compounds that not responsible for antioxidant activity, therefore at the same concentration the activity were lower than vitamin E.

    Full Text Available The effects of the aqueous root extract of urena lobata on the rat liver was investigated using a total of (25 adult Wister rats of both sexes that were randomly divided into five groups of five rats each. Group I served as the control, while rats in groups II-IV where administered 100, 200 and 300 mg/kg body weight of the extract, respectively for 28 days. Rats in group V were administered 300 mg/kg of the extract for 28 days and allowed to stay for 14 days post treatment to observe for reversibility, persistence or delayed occurrence of toxic effects. At the end of the experimental period the animals were sacrificed and liver weight taken and fixed for routine histological examinations. Administration of the extract to rats had no effects on liver and body weights but the extract caused a decrease in albumin level and increases in the levels of Aspartate Transaminases (AST, Alanine Transaminases (ALT and Alkaline Phosphatase (ALP. Histopathological assessment of the liver revealed mild to severe interstitial hemorrhage, mononuclear cell infiltration, necrosis, congestion and edema in the liver of the treated rats while withdrawal of the extract for 14 days showed a slight degree of recovery in the rats. This findings suggest that the biochemical and morphological organization of the liver can significantly be altered with continues and increase use of the extract, but further studies on the long term effect of the extract and a prolonged recovery period is recommended in further studies.

    Since the discovery and subsequent widespread use of antibiotics, a variety of bacterial species of human and animal origin have developed numerous mechanisms that render bacteria resistant to some, and in certain cases to nearly all antibiotics, thereby limiting the treatment options and compromising effective therapy. In the present study, the green synthesis of nanoparticles is carried out by the reduction of silver acetate in the presence of crude methanolic root extracts of Diospyros paniculata, a member of family Ebenaceae. The UV–Vis absorption spectrum of the biologically reduced reaction mixture showed the surface plasmon peak at 428 nm, a characteristic peak of silver nanoparticles. X-ray diffraction (XRD) analysis confirmed the face-centered cubic crystalline structure of metallic silver. The average diameter of Ag NPs is about 17 nm from Transmission Electron Microscopy (TEM) which is in good agreement with the average crystallite size (19 nm) calculated from XRD analysis. Further the study has been extended to the antimicrobial activity against test pathogenic Gram (+), Gram (−) bacterial and fungal strains. The biologically synthesized silver nanoparticles showed promising activity against all the tested pathogenic strains and the activity has been enhanced with the increased dose levels. - Highlights: • Biosynthesis of silver nanoparticles (Ag NPs) using root extracts of Diospyros paniculata. • Average diameter of Ag NPs is about 17 nm from TEM analysis which is in good agreement with XRD analysis. • Antimicrobial activities of root extract mediated synthesis of silver Ag NPs were discussed in detail.

  20. Devil's Claw to suppress appetite--ghrelin receptor modulation potential of a Harpagophytum procumbens root extract.

    Directory of Open Access Journals (Sweden)

    Cristina Torres-Fuentes

    Full Text Available Ghrelin is a stomach-derived peptide that has been identified as the only circulating hunger hormone that exerts a potent orexigenic effect via activation of its receptor, the growth hormone secretagogue receptor (GHS-R1a. Hence, the ghrelinergic system represents a promising target to treat obesity and obesity-related diseases. In this study we analysed the GHS-R1a receptor activating potential of Harpagophytum procumbens, popularly known as Devil's Claw, and its effect on food intake in vivo. H. procumbens is an important traditional medicinal plant from Southern Africa with potent anti-inflammatory and analgesic effects. This plant has been also used as an appetite modulator but most evidences are anecdotal and to our knowledge, no clear scientific studies relating to appetite modulation have been done to this date. The ghrelin receptor activation potential of an extract derived from the dried tuberous roots of H. procumbens was analysed by calcium mobilization and receptor internalization assays in human embryonic kidney cells (Hek stably expressing the GHS-R1a receptor. Food intake was investigated in male C57BL/6 mice following intraperitoneal administration of H. procumbens root extract in ad libitum and food restricted conditions. Exposure to H. procumbens extract demonstrated a significant increased cellular calcium influx but did not induce subsequent GHS-R1a receptor internalization, which is a characteristic for full receptor activation. A significant anorexigenic effect was observed in male C57BL/6 mice following peripheral administration of H. procumbens extract. We conclude that H. procumbens root extract is a potential novel source for potent anti-obesity bioactives. These results reinforce the promising potential of natural bioactives to be developed into functional foods with weight-loss and weight maintenance benefits.

    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.

    An in vitro skin diffusion study of pure forskolin (1) versus a 1-containing Plectranthus barbatus root extract (P. barbatus extract) in hairless guinea pig skin and human skin in a flow-through diffusion cell system was conducted and is being reported for the first time. Both topical agents were formulated in a solution of 70% ethanol and 30% propylene glycol (v/v). The results showed that forskolin can be delivered through the stratum corneum and that the flux of this compound was enhanced when 1 was delivered as a constituent of the P. barbatus extract as compared to an equivalent amount in pure form. These results suggest that the P. barbatus extract used contains permeation enhancement activity from other compound(s) contained in the crude root extract. It is possible that P. barbatus root extract may be used as an economical source of 1 to perform topical chemical manipulation of pigmentation in high-risk populations. PMID:19281221

    In the present study, an ethanolic root-bark extract of Moringa oleifera (MO) was examined for its antiulcer potential in albino Wistar rats using two experimental models: ethanol-induced and pylorus ligation-induced gastric ulceration. The extract was orally administered at three different doses (150, 350, and 500 mg/kg) for 15 consecutive days. The antiulcer effects in rats treated with different doses of the extract and omeprazole (30 mg/kg, p.o.) were determined and compared statistically with the antiulcer effects in the control rats treated with saline (NaCl, 0.9%). The MO at doses of 350 and 500 mg/kg decreased the ulcer index significantly as compared to the control group (p Moringa oleifera can be used as source for an antiulcer drug.

    Proteomics is an outstanding area in science whose increasing application has advanced to distinct purposes. A crucial aspect to achieve a good proteome resolution is the establishment of a methodology that results in the best quality and wide range representation of total proteins. Another important aspect is that in many studies, limited amounts of tissue and total protein in the tissue to be studied are found, making difficult the analysis. In order to test different parameters, combinations using minimum amount of tissue with 4 protocols for protein extraction from tomato (Solanum lycopersicum L.) leaves and roots were evaluated with special attention to their capacity for removing interferents and achieving suitable resolution in bidimensional gel electrophoresis, as well as satisfactory protein yield. Evaluation of the extraction protocols revealed large protein yield differences obtained for each one. TCA/acetone was shown to be the most efficient protocol, which allowed detection of 211 spots for leaves and 336 for roots using 500 µg of leaf protein and 800 µg of root protein per gel.

    Full Text Available Objective: Diabetes mellitus is the most common metabolic disorders with severe impact on quality of life. Reducing serum glucose levels and normalization of serum lipid is of great clinical importance for treating diabetes. To our knowledge, there are not any evidences about the anti-diabetic action of capparis spinosa root. In the present study the effects of the C. spinosa root extract on diabetic metabolic disorders have been studied in experimental diabetes. Materials and Methods: Rats were divided into six groups: normal control (NC, diabetic control (DC, diabetic rats receiving 0.2, 0.4 g/kg of plant extract or 0.6 mg/kg glibenclamide (groups D0.2, D0.4 or DG respectively. A normal group of rats was also designed to receive 0.2 g/kg of plant extract (N0.2. Rats were rendered diabetic (streptozotocin 60 mg/kg, i.p. and treated with 0.2, 0.4 g/ kg of plant extract or glibenclamide for four weeks. At the end of the experiment, blood was drawn through heart puncture under deep anesthesia. Weight was measured weekly, glucose levels were measured at the first and fourth week and lipid profiles, insulin and liver enzymes at the end of the study. Results: Glucose levels significantly decreased after treating with plant extract (p=0.003. However, insulin levels did not increase in any treating groups. Plant extract could significantly raise HDL and reduce levels of LDL and liver enzymes (ALT and ALP. Conclusion: These results showed that C. spinosa rootextract could improve diabetic related metabolic derangement such as hyperglycemia, dyslipidemia, and elevated liver markers in an insulin-independent manner.

    Clerodendrum paniculatum L. (Family Verbenaceae) has been used as an antipyretic and anti-inflammatory drug in traditional Thai medicine. This present study investigated the in vitro anti-inflammatory, mutagenic and antimutagenic activities of the ethanolic extract of C. paniculatum (CPE) dried root collected from Sa Kaeo Province of Thailand. Murine macrophage J774A.1 cells were stimulated by lipopolysaccharide (LPS) to evaluate nitric oxide (NO), tumor necrosis factor-α (TNF-α) and prostaglandin E2 (PGE2) production in the anti-inflammatory test while the mutagenic and antimutagenic potential was performed by the Ames test. The outcome of this study displayed that the CPE root significantly inhibited LPS-induced NO, TNF-α, and PGE2 production in macrophage cell line. In addition, the CPE root was not mutagenic toward Salmonella typhimurium strain TA98 and TA100 with and without nitrite treatment. Moreover, it inhibited the mutagenicity of nitrite treated 1-aminopyrene on both strains. The findings suggested the anti-inflammatory and antimutagenic potentials of CPE root.

    Full Text Available Sechium edule is traditionally used in Mexico as a therapeutic resource against renal diseases and to control high blood pressure. The purpose of this work is to evaluate the antihypertensive effect of the hydroalcoholic extract obtained from the roots of this plant, including its fractions and subfractions, on different hypertension models induced with angiotensin II (AG II. The hydroalcoholic extract was tested on an in vitro study of isolated aorta rings denuded of endothelial cells, using AG II as the agonist; this assay proved the vasorelaxant effect of this extract. Vagotomized rats were administered different doses of AG II as well as the Hydroalcoholic extract, which reduced blood pressure in 30 mmHg approximately; subsequently this extract was separated into two fractions (acetone and methanol which were evaluated in the acute hypertension mouse model induced with AG II, where the acetone fraction was identified as the most effective one and was subsequently subfractioned using an open chromatographic column packed with silica gel. The subfractions were also evaluated in the acute hypertension model. Finally, the extract, fraction, and active subfraction were analyzed by MS-PDA-HPLC, identifying cinnamic derivative compounds like cinnamic acid methyl ester.

    Full Text Available Global HIV-1 treatment would benefit greatly from safe herbal medicines with scientifically validated novel anti-HIV-1 activities. The root extract from the medicinal plant Pelargonium sidoides (PS is licensed in Germany as the herbal medicine EPs®7630, with numerous clinical trials supporting its safety in humans. Here we provide evidence from multiple cell culture experiments that PS extract displays potent anti-HIV-1 activity. We show that PS extract protects peripheral blood mononuclear cells and macrophages from infection with various X4 and R5 tropic HIV-1 strains, including clinical isolates. Functional studies revealed that the extract from PS has a novel mode-of-action. It interferes directly with viral infectivity and blocks the attachment of HIV-1 particles to target cells, protecting them from virus entry. Analysis of the chemical footprint of anti-HIV activity indicates that HIV-1 inhibition is mediated by multiple polyphenolic compounds with low cytotoxicity and can be separated from other extract components with higher cytotoxicity. Based on our data and its excellent safety profile, we propose that PS extract represents a lead candidate for the development of a scientifically validated herbal medicine for anti-HIV-1 therapy with a mode-of-action different from and complementary to current single-molecule drugs.

    Full Text Available Background and Aims: Salvia miltiorrhiza Bunge (Labiatae is a Chinese medicinal plant, the dried roots of which (known as Dan-Shen have been used for hundreds of years in the treatment of a series of ailments, including hyperglycemia. This study was designed to evaluate the hypoglycemic effect of a new, standardized extract of S. miltiorrhiza. Materials and Methods: S. miltiorrhiza extract (containing 21% total tanshinones and 3.7% tanshinone IIA was administered acutely and intragastrically at the doses of 0, 50, 100, and 200 mg/kg to male, healthy, fasted Wistar rats 60 min before the intragastric infusion of a bolus of starch (3 g/kg; a semi-naturalistic experimental condition (Experiment 1 or glucose (2 g/kg (Experiment 2. Results: In both experiments, treatment with S. miltiorrhiza extract produced a dose-related decrease in glycemia, evidenced in terms of reduction of peak value and/or area under the curve of the time-course of glycemia. The effect of S. miltiorrhiza extract occurred at doses devoid of any behavioral toxicity in rats. Conclusion: The results of this study suggest that the hypoglycemic effect of S. miltiorrhiza extract was likely secondary to an action on carbohydrate metabolism. These results are consistent with several preclinical and clinical data and add further support to the hypothesis that S. miltiorrhiza extracts may act as effective anti-hyperglycemic remedies.

    Full Text Available In order to evaluate the therapeutic potential of polyphenolic extracts from root bark of M. arboreus, we have determined the content of various polyphenols in aqueous and ethanol (EtOH extract as well as two sub-fractions of the latter: ethyl acetate (EAc and hexane (Hex. The total phenols, flavonoids, hydroxycinnamic acids and proanthocyanidins have been determined for all studied extracts/fractions by spectrophotometric methods. Both TP content (331.5 ± 2.5 mg GAE/g and HCA content (201 ± 1.5 mg CAE/g were determined to be the highest in EAc fraction of EtOH extract. All studied extracts were however determined to have a low content in flavonoids. The determination of antioxidant capacities of the studied extracts has also been performed by the following in vitro antioxidant tests: DPPH scavenging, phosphomolybdenum method and oxygen radical absorbance (ORACFl and ORACPRG assay. The results of the DPPH free radical and ORACFl assays showed that there is no significant difference between the EAc fraction and Oligopin®, but the EAc fraction exhibited the highest antioxidant capacity as determined by the phosphomolybdenium method. In addition, the EtOH extract was determined to have the same antioxidant efficiency as the synthetic antioxidant BHT or commercial extract Oligopin® by phosphomolybdenum method. On the other hand, a positive correlation (r < 0.6 was found between different classes of polyphenols and the results of the phosphomolybdenum method, ORACFl as well as ORACPRG, except for the DPPH assay, for which a negative correlation was indicated (r < 0.62. Interestingly, it seems that the content in hydroxycinnamic acids played a big role in all assays with r < 0.9. According to the present study, EAc fraction and EtOH extract should be further studied for the potential use in the pharmaceutical and food industry.

    Many challenges are associated with the oral delivery of insulin, relating to the physical and chemical stability of the hormone, and its absorption and metabolism in the human body. The present study aims to demonstrate the oral delivery of insulin in both normal and steptozotocin (STZ)-induced diabetic rats with the help of the aqueous extract of Desmodium gangeticum (DG) root. Human insulin was mixed with the aqueous extract of DG root (0.1 mg/ml) with human insulin (40 IU/ml) in ratio 1:1(v/v), to prepare oral insulin drug. Decreased plasma glucose level and increased plasma insulin in normal and STZ-induced diabetic rat suggested the probable absorption of insulin through GI tract when insulin was administered by mixing with DG extract. Indeed, insulin mixed DG potentially stimulates the release of insulin in STZ-induced diabetic rat rather than in normal animal. In vivo insulin secretaguage action of oral insulin drug was determined by isolated rat heart model and the results showed a significant cardio protection in STZ rat. The finding of this study suggests that insulin mixed with DG extract can be a promising vehicle for oral delivery of insulin. However, further studies are required to explore the exact compound(s) responsible for the protective delivery of insulin orally. Increased plasma insulin level by insulin mixed DG extract administration in STZ-treated diabetic rat indicates not only insulin secretaguage action of the mixture but also a probable altered insulin release mechanism in diabetic condition.

The safety assessment of root extract was done in mice on the basis of general signs and symptoms of toxicity, food water intake and mortality of animals following their treatment with various doses of extract (100 and ndash;3200 mg/kg. In addition, the serum glutamate oxaloacetate transaminase (SGOT, serum glutamate pyruvate transaminase (SGPT, cholesterol and total protein of experimental mice were also monitored to assess the toxicity of root extract. Results: In the safety assessment studies, P. fulgens root extract did not showed any visible signs of toxicity, but mortality was observed in a single animal at 3200 mg/kg dose of extract. The extract also did not showed any adverse effects on the studied serum parameters of experimental animals. In the antidiarrhoeal tests, administration of 800 mg/kg dose of extract to mice showed 50% protection from diarrhoea evoked by castor oil. In addition, the extract also showed 29.27% reduction in PGE2-induced intestinal secretion as compared to 30.31% recorded for loperamide, a standard anti-diarrhoeal drug. Conclusions: The results of this study indicate that P. fulgens root extract possesses significant anti-diarrhoeal properties. Therefore, the roots of this plant can be an effective traditional medicine for the protection from diarrhoea. [J Intercult Ethnopharmacol 2014; 3(3.000: 103-108

    Previous results have demonstrated that extracts derived from maturing male sex organs of Chara tomentosa are capable of inducing profound structural and functional effects upon M-phase cells in the primary root meristems of Melandrium noctiflorum and Allium cepa. Evident changes produced by a putative factor engaged in morphogenesis of antheridial filaments are manifested by: (1) significant shortening of chromosomes, (2) decreased mitotic indices, and (3) altered proportions estimated for the prophase and telophase transit times. The present image analysis of late G2 phase nuclei in antheridial filaments of C. tomentosa supports the concepts that progressive changes of their functional activities correspond closely to the increasing proportion of condensed chromatin. Cytophotometric measurements of Feulgen-stained cell nuclei in root meristems after a prolonged incubation in antheridial extracts revealed that cells which previously divided asynchronously became preferentially arrested in G1 (M. noctiflorum) and G2 (A. cepa). The stages at which the cells arrest are supposed to counterpart restriction checkpoints that prevent the initiation of DNA synthesis and mitosis. This assumption has been confirmed by autoradiographic studies using 3H-thymidine. In terms of the "Principal Control Points" (PCP) hypothesis, the obtained results suggest that two PCPs regulate G1-->S and G2-->M transition in a nuclear structure-dependent and a species-specific manner. Although in antheridial extract-treated roots of both M. noctiflorum and A. cepa there are only slight changes in the levels of chromatin condensation, the relative proportions of G1- and G2-arrested cells and their nuclear density profiles differ, as compared with the control and carbohydrate-starved plants.

    Phytosynthesis of silver nanoparticles has attracted considerable attention due to their biocompatibility, low toxicity, cost-effectiveness and being a novel method has an eco-friendly approach. Biological activity of root extracts as well as synthesized silver nanoparticles of Catharanthus roseus were evaluated against larvae of Aedes aegyptiand Culex quinquefasciatus. The structure and proportion of the synthesized nanoparticles was defined by exploitation ultraviolet spectrophotometry, X-ray diffraction, fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy and scanning electron microscopy methods. Reduction of silver ions occurred when silver nitrate solution was treated with aqueous root extract at 60°C. Synthesized silver nanoparticles (AgNPs) were confirmed by analyzing the excitation of surface plasmon resonance (SPR) using UV-vis spectrophotometer at 423 nm. FTIR showed aliphatic amines and alkanes corresponding peaks to be presence of responsible compounds to produced nanoparticles in the reaction mixture. Spherical shaped and crystalline nature of particles was recorded under XRD analysis. Presence of silver metal and 35-55nm sized particles were recorded using EDAX and SEM respectively. Larvicidal activitywas observed after24 hrs of exposure to root extracts and synthesized silver nanoparticles. The highest larval mortality was observed in synthesized silver nanopartiucles against Aedes aegypti (LC50= 2.01 ± 0.34; LC90= 5.29 ± 0.07 at 5.0 mg(-1) concentration) and Culex quinquefasciatus (LC50= 1.18 ± 0.15; LC90= 2.55 ± 0.76 at 3.5 to 5.0 mgl(-1) concentration) respectively. The present study provides evidence that synthesized silver nanoparticles of Catharanthus roseus offer potential source for larvicidal activity againstthe larvae of both dengue and filariasis vectors.

    Full Text Available Diabetes mellitus is a chronic metabolic disorder associated with hyperglycemia, oxidative stress and dyslipidemia. Hemidesmus indicus is employed as an indigenous medicine for a variety of ailments from earlier days. The present study was aimed to evaluate the role of Hemidesmus indicus in alloxan-induced experimental diabetic rats. The effect of oral administration of Hemidesmus indicus root extract (400 mg/kg b.w. on glucose tolerance, the levels of blood glucose, hemoglobin, glycosylated hemoglobin, plasma insulin, protein, lipid peroxides, enzymatic and non-enzymatic antioxidants, lipid profile, muscle glycogen content were determined in control and experimental groups of rats. The altered levels of blood glucose, hemoglobin, glycosylated hemoglobin, plasma insulin, and protein in the diabetic rats were significantly reverted back to near basal values by the administration of ethanol extract of Hemidesmus indicus root to diabetic rats for 30 days. The levels of lipid peroxides in the plasma and pancreatic tissues of diabetic rats were elevated significantly and were normalized by the administration of Hemidesmus indicus root extract. The activities of pancreatic enzymic antioxidants and the levels of plasma non-enzymic antioxidants were markedly declined in the diabetic rats. Upon treatment with Hemidesmus indicus root extract to diabetic rats, these decreased levels were elevated to near normal values. The reduced level of glycogen content in muscle tissues of diabetic rats was significantly improved upon treatment with Hemidesmus indicus root extract. The altered levels of lipid profile were reverted back to near normalcy upon the extract treatment. The results of the study indicate that Hemidesmus indicus root extract possesses antihyperglycemic, antioxidant and antidyslipidemic activity. The results are comparable with glyclazide, an oral standard hypoglycemic drug. The phytochemicals present in the Hemidesmus indicus root extract may

    Methanol and chloroform extracts were prepared from various parts of four plants collected in Mali: Guiera senegalensis (Gmel.) Combretaceae, Feretia apodanthera (Del.) Rubiaceae, Combretum micranthum (Don.) Combretaceae, Securidaca longepedunculata (Fres.) Polygalaceae and two plants -collected in Sao Tome: Pycnanthus angolensis (Welw.) Myristicaceae and Morinda citrifolia (Benth.) Rubiaceae were assessed for their in vitro antimalarial activity and their cytotoxic effects on human monocytes (THP1 cells) by flow cytometry. The methanol extract of leaves of Feretia apodanthera and the chloroform extract of roots of Guiera senegalensis exhibited a pronounced antimalarial activity. Two alkaloids isolated from the active extract of Guiera senegalensis, harman and tetrahydroharman, showed antimalarial activity (IC(50) lower than 4 microg/mL) and displayed low toxicity against THP1. Moreover, the decrease of THP1 cells in S phase of the cell cycle, after treatment with harman and tetrahydroharman, was probably due to an inhibition of total protein synthesis.

    Acetylcholinesterase inhibitors (AChEIs) are important for treatment of Alzheimer's disease and other neurological disorders. Search for potent and safe AChEIs from plant sources still continues. In the present work, we explored fragrant plant extracts that are traditionally used in flavoring foods, namely, Hemidesmus indicus and Vanilla planifolia, as possible sources for AChEI. Root and pod extracts of H. indicus and V. planifolia, respectively, produce fragrant phenolic compounds, 2-hydroxy-4-methoxybenzaldehyde (MBALD) and 4-hydroxy-3-methoxybenzaldehyde (vanillin). These methoxybenzaldehydes were shown to have inhibitory potential against acetylcholinesterase (AChE). Vanillin (IC50 = 0.037 mM) was detected as more efficient inhibitor than MBALD (IC50 = 0.047 mM). This finding was supported by kinetic analysis. Thus, plant-based food flavoring agents showed capacity in curing Alzheimer's disease and other neurological dysfunctions.

    Objective: The present investigation deals with evaluation of antidiabetic (Type 2) activity of standardized alcoholic root extracts of Caesalpinia digyna in STZ-nicotinamide induced diabetic rats. Methods: Alcoholic root extract of Caesalpinia digyna (ACD), obtained from Soxhlet extractor was standardized by HPLC. Type 2 diabetes was induced by single intraperitoneal injection of nicotinamide (110 mg/kg) followed by streptozotocin (65 mg/kg). Diabetic rats ware administered ACD at doses of 250, 500, and 750 mg/kg (p.o.) and different parameters such as normoglycemic and oral glucose tolerance test were evaluated. The study also included estimations of blood plasma glucose, lipid profile, liver glycogen, body weight and anti-oxidant status in normal and diabetic rats. Results: Normoglycemic rats did not reduce the blood glucose level, whereas oral glucose tolerance test showed better tolerance of glucose in treated rats. The alcoholic extract showed a dose dependent reduction in fasting blood glucose level i.e. more pronounced at 750 mg/kg (P<0.05). ACD showed significant reduction in plasma lipid like triglycerides, total cholesterol and improvement in high density lipo-protein cholesterol (HDL-C) in treated groups. The decrease in lipid peroxides and increase in superoxide dismutase (SOD) and catalase (CAT) in liver clearly showed the antioxidant potential while rat hemi-diaphragm glucose uptake study revealed increases in peripheral glucose uptake of treated rats. Conclusions: Results showed that standardized alcoholic extract of C. digyna possessed significant antidiabetic activity which may be attributed to increase in glycogen storage, hypolipidemic and antioxidant activity thus, rationalizing its traditional use.

    An efficient protein extraction method is crucial to ensure successful separation by two-dimensional electrophoresis(2-DE)for recalcitrant plant species, in particular for grapevine(Vitis vinifera L.). Trichloroacetic acid-acetone(TCA-acetone)and phenol extraction methods were evaluated for proteome analysis of leaves and roots from the Tunisian cultivar 'Razegui'. The phenol-based protocol proved to give a higher protein yield,a greater spot resolution, and a minimal streaking on 2-DE gels for both leaf and root tissues compared with the TCA-based protocol. Furthermore, the highest numbers of detected proteins on 2-DE gels were observed using the phenol extraction from leaves and roots as compared with TCA-acetone extraction.

    Securinega virosa (Roxb ex. Willd) Baill. is a plant which is commonly used in African traditional medicine in management of mental illness. Previous study showed that the crude methanolic root bark extract of the plant possesses antipsychotic activity. In this study, the antipsychotic potential of the residual aqueous fraction of the plant was evaluated using two experimental models, apomorphine induced stereotypic climbing behaviour and swim induced grooming, all in mice. The effect of the fraction on haloperidol-induced catalepsy was also evaluated. The fraction significantly reduced the mean climbing score at the highest dose tested (500 mg/kg). In the swim-induced grooming test, the fraction significantly and dose-dependently (125-500 mg/kg) decreased the mean number and mean duration of swim-induced grooming activity in mice. Similarly, the standard haloperidol (1 mg/kg) significantly (p < 0.001) decreased the mean grooming episodes and duration. However, the fraction did not significantly potentiate haloperidol-induced catalepsy. These results suggest that the residual aqueous fraction of methanol root bark extract of Securinega virosa contains biological active principle with antipsychotic potential.

    Full Text Available The synthesis of ZnO nanoparticles using biological method is always eco friendly and attractive. The current study focuses on the production of ZnO nanoparticles using the aqueous root extracts of Zingiber officinale (ginger. The root extracts were found to be rich in flavonoids which were confirmed by the flavonoid test thereby enhancing the biogenic synthesis of ZnO nanoparticle. The Scanning Electron Microscope with the Energy Dispersive X-ray studies were used for characterization that provides the size and the elemental composition of the synthesized ZnO nanoparticles. The average size of the nanoparticles was found to be 30-50nm. The FTIR analysis played a pivotal role in displaying the important functional groups present in the ZnO nanoparticle, which showed that the sample had strong absorbance in the range of 1600 – 1450 cm-1. Hence the biogenic synthesis of ZnO nanoparticles using Zingiber officinale, can be an alternative to chemical synthesis.

    The antioxidant activity of methanolic extracts derived from shoots (HR-shoots) and roots (HR-roots) of pRi-transformed Rehmannia glutinosa plants were determined. The activity was indicated by the ability of the plant extracts to inhibit superoxide anion (O2(-·)) generation and thiobarbituric acid reactive substances (TBARS) production in resting blood platelets and platelets activated by thrombin. The strongest activity was exhibited by the HR-shoot extract (50 μg/mL). The present study also examines the antioxidant properties of the plant extracts against human plasma lipid peroxidation induced by strong biological oxidants: hydrogen peroxide (H2O2) and H2O2/Fe. The study shows that extracts from transformed R. glutinosa plants may be a promising source of natural antioxidants, which would be valuable in various cardiovascular diseases. The extracts may also protect lipids against oxidative modifications.

    Ferula hermonis Boiss. is an aphrodisiac plant that grows in the Mediterranean region. It has been reported that treatment with acetonic extract from the root of this plant acutely increases serum testosterone in the rat. This study investigated the effects of F. hermonis extract alone or combined with exercise on rat skeletal muscle fibers. Adult male rats were divided into four groups: control-sedentary (CS) that had no treatment or exercise; ferula-sedentary (FS) that was orally treated with ferula extract at a dose of 60 mg/kg/rat every other day over a period of 20 d; control-exercised (CE) that was trained by swimming for 40 min every other day; and ferula-exercised (FE) that received ferula and performed exercise. At the end of experiments, the fiber diameter and number of muscle nuclei of tibialis anterior were measured by using immunofluorescent techniques and software analyses. The FE group showed significant increases in muscle weight, fiber size and nuclear number compared with the other groups. However, no significant changes in the aforementioned parameters were found among the CS, FS and CE groups. Ferula treatment and exercise were additive to each other. In conclusion, short-term exercise combined with administration of F. hermonis extract was more effective in enhancing the growth of skeletal muscle fibers than exercise alone.

    Liquid media containing potato extract and 1% of glucose or sucrose were used to culture root-nodule bacteria (rhizobia) in shaken Erlenmeyer flasks. For comparison, these bacteria were also cultured in yeast extract-mannitol broth (YEMB) as a standard medium. Proliferation of rhizobia was monitored by measuring optical densities (OD550) of the cultures and by plate counting of the viable cells (c.f.u) of the bacteria. In general, multiplication of the rhizobia in potato extract-glucose broth (PEGB) and potato extract-sucrose broth (PESB) was markedly faster, as indicated by higher values of OD550, than in YEMB. The numbers of R. leguminosarum by. vicae GGL and S. meliloti 330 in PEGB and PEGB were high and ranged from 1.2 x 10(10) to 4.9 x 10(10) mL(-1) after 48 h of incubation at 28 degrees C. B. japonicum B3S culture in PEGB contained 6.4 x 10(9) c.f.u. ml(-1) after 72 h of incubation. PEGB and YEMB cultures of the rhizobia were similar with respect to their beneficial effects on nodulation of the host-plants of these bacteria.

    Formation of urinary stone is a serious and debilitating problem throughout the world. In the present study, the inhibitory effect of aqueous extract of root of Rotula aquatica was investigated against struvite crystals (one of the components of urinary stone) grown in vitro using single diffusion gel growth technique. For setting the gel, sodium metasilicate solution (specific gravity 1.05) and 0.5 M aqueous solution of ammonium dihydrogen phosphate were mixed, so that the pH of the mixture could be set at 7.0. Equal amounts of supernatant solution of magnesium acetate (1.0 M) prepared with 0.0%, 0.5% and 1% concentrations of the extract were gently poured on the set gels. It was observed that the number, dimension, total mass, total volume, growth rate and depth of growth of struvite crystals decreased with the increasing extract concentrations in the supernatant solutions. The enhancement of dissolution rate and fragmentation of struvite crystals suggested potential application of the extract for inhibition of struvite type urinary stone.

    The present study was undertaken to investigate the cardiovascular effect of three extracts from the root bark of Anthocleista schweinfurthii Gilg.: an aqueous extract (AE), a dichloromethane extract (DCMR) and a fraction enriched in cardiac glycoside type compounds (CARDAN). In isolated perfused frog heart, bolus injection of the extracts produced a positive inotropic effect. The responses to AE and DCMR, but not to CARDAN, were depressed by propranolol. In isolated rat aorta, DCMR produced a transient increase in contractile tension while AE and CARDAN induced a sustained constriction. AE vasoconstrictor effect was abolished by phentolamine, while contraction evoked by CARDAN was antagonized by verapamil. In aortic rings contracted in low K+ media, the addition of K+ evoked a relaxation, which was abolished by ouabain, depressed by DCMR but not affected by either A(E) or CARDAN. These observations indicate that Anthocleista schweinfurthii contains substances that promote vasoconstriction and increase cardiac contraction. The effect of DCMR was only partially mediated by inhibition of the Na+ pump while the mechanism of action of A(E) and CARDAN was distinct from the inhibition of the Na+, K+ - ATPase pump, but could involve adrenergic receptors, or either direct or indirect activation of L-type calcium channels.

Aims: To investigate the possible cardioprotective activity of a DG root extract against isoproterenol (ISO-induced left ventricular cardiac hypertrophy (LVH in adult Wistar rats. Methods: Daily intraperitoneal administration of ISO (10 mg/kg body weight, single injection for 7 days induced LVH in rats. The LVH rats were post-treated orally with DG (100 mg/kg body weight for a period of 30 days. Thereafter, changes in heart weight (HW and body weight (BW, HW/BW ratio, percent of hypertrophy, collagen accumulation, activities of matrix metalloproteinase (MMP -2 and -9, superoxide dismutase (SOD and catalase (CAT enzymes, and the level of an oxidative stress marker, lipid peroxide (LPO, were determined. Results: HW/BW ratio, an indicator of hypertrophic growth, was significantly reduced in DG root post-treated LVH rats as compared with that for the non-treated LVH rats. The altered levels of ventricular LPO, collagen, MMPs-2 and -9, and antioxidant enzymes in the ISO-treated animals reverted back to near normal upon DG treatment. Further, the anti-hypertrophic activity of DG was comparable to that of the standard drug losartan (10 mg/kg. Conclusions: The results of the present study suggest that the aqueous root extract of DG exhibited anti-hypertrophic activity in-vivo by inhibiting ISO-induced ROS generation and MMP activities.

    Hepatitis C virus (HCV) is a serious global health problem affecting approximately 130-150 million individuals. Presently available direct-acting anti-HCV drugs have higher barriers to resistance and also improved success rate; however, cost concerns limit their utilization, especially in developing countries like India. Therefore, development of additional agents to combat HCV infection is needed. In the present study, we have evaluated anti-HCV potential of water, chloroform, and methanol extracts from roots of Valeriana wallichii, a traditional Indian medicinal plant. Huh-7.5 cells infected with J6/JFH chimeric HCV strain were treated with water, chloroform, and methanol extracts at different concentrations. Semi-quantitative reverse transcription polymerase chain reaction result demonstrated that methanolic extract showed reduction in HCV replication. The methanolic extract was fractionated by thin layer chromatography, and the purified fractions (F1, F2, F3, and F4) were checked for anti-HCV activity. Significant viral inhibition was noted only in F4 fraction. Further, intrinsic fluorescence assay of purified HCV RNA-dependent RNA polymerase NS5B in the presence of F4 resulted in sharp quenching of intrinsic fluorescence with increasing amount of plant extract. Our results indicated that methanolic extract of V. wallichii and its fraction (F4) inhibited HCV by binding with HCV NS5B protein. The findings would be further investigated to identify the active principle/lead molecule towards development of complementary and alternative therapeutics against HCV.

    Solvent-modified carbon dioxide extractions of the roots of Harpagophytum procumbens have been investigated with respect to extraction efficiency and content of harpagoside, and compared with a conventional extract. The effects of pressure, temperature, type and concentration of the modifier have been examined. Two extraction steps were necessary in order to achievehigh anti-inflammatory harpagoside-enriched extracts. The first extraction step was carried out in the supercritical state using carbon dioxide modified with n-propanol to remove undesired lipophilic substances. The main extraction was performed either in the supercritical or in the subcritical state with carbon dioxide modified with ethanol. The supercritical fluid extraction resulted in extracts containing up to 30% harpagoside. The subcritical extracts showed a harpagoside content of ca. 20%, but the extraction yield was nearly three times greater compared with supercritical conditions. The total harpagoside recovery resulting from the sum of the extract and the crude drug residue was greater than 99% in all experiments. The conventional extract and two carbon dioxide extracts were tested for in-vitro inhibition of 5-lipoxygenase or cyclooxygenase-2 biosynthesis. Both carbon dioxide extracts showed total inhibition on 5-lipoxygenase biosynthesis at a concentration of 51.8 mg/L. In contrast, the conventional extract failed to show any inhibition of 5-lipoxygenase biosynthesis.

The noni plant has a long history of use as a medicinal plant to treat a wide variety of ailments including CNS disorders. The present investigation was designed to evaluate the antipsychotic effect of noni fruits (Morinda citrifolia Linn. using mouse models of apomorphine-induced climbing behaviour and methamphetamine-induced stereotypy (licking, biting, gnawing and sniffing. Methods In acute study, the methanolic extract of Morinda citrifolia (MMC at different doses 1, 3, 5, 10 g/kg was administered orally one hour prior to apomorphine (5 mg/kg, i.p and methamphetamine ( 5 mg/kg, i.p injection respectively in Swiss albino mice. In chronic studies, (TAHITIAN NONI® Juice, TNJ was made available freely in daily drinking water at 30, 50 and 100% v/v for 7 days; 30 and 50% v/v for 21 days respectively. On the test day, an equivalent average daily divided dose of TNJ was administered by oral gavage one hour prior to apomorphine treatment. Immediately after apomorphine/ methamphetamine administration, the animals were placed in the cylindrical metal cages and observed for climbing behaviour/ stereotypy and climbing time. Results The acute treatment of MMC (1, 3, 5, 10 g/kg, p.o significantly decreased the apomorphine-induced cage climbing behaviour and climbing time in mice in a dose dependent manner. The MMC also significantly inhibited methamphetamine-induced stereotypy behaviour and climbing time in mice dose-dependently. The 7 and 21 days treatment of TNJ in drinking water at 50 and 100%v/v significantly alleviated the apomorphine-induced climbing behaviour and climbing time in mice. Conclusions The present study results demonstrated the antidopaminergic effect of Morinda citrifolia Linn. in mice, suggesting that noni has antipsychotic-like activity which can be utilized in the treatment of psychiatric disorders.

The present study therefore investigated the effects of aqueous extract of Arctium lappa L. roots on sexual behavior in normal male rats. Methods Seventy-five albino male rats were randomly divided into five groups of 15 rats each. Rats in group 1 (control were administered 10 mL⁄kg body weight distilled water (vehicle, group 2 received 60 mg/kg body weight sildenafil citrate (Viagra, while those in groups 3, 4, and 5 were given 300, 600, and 1,200 mg/kg body weight, respectively, of aqueous extract of Arctium lappa L. roots in the same volume. Female albino rats were made receptive by hormonal treatment. Sexual behavior parameters in male rats were monitored on days 3, 7 and 15 by pairing with receptive females (1:3. Male serum testosterone concentrations and potency were also determined. Results Oral administration of Arctium lappa L. roots extract at 600 and 1,200 mg/kg body weight significantly increased the frequencies of mount, intromission, and ejaculation frequency (p Conclusions The results of this study demonstrate that aqueous extract of Arctium lappa L. roots enhances sexual behavior in male rats. The aphrodisiac effects of the plant extract may be related to the presence of flavonoids, saponins, lignans and alkaloids, acting via a multitude of central and peripheral mechanisms. These results thus support the traditional use of Arctium lappa L. root extract for treating impotence and sterility.

    Theobroma cacao is a woody and recalcitrant plant with a very high level of interfering compounds. Standard protocols for protein extraction were proposed for various types of samples, but the presence of interfering compounds in many samples prevented the isolation of proteins suitable for two-dimensional gel electrophoresis (2-DE). An efficient method to extract root proteins for 2-DE was established to overcome these problems. The main features of this protocol are: i) precipitation with trichloroacetic acid/acetone overnight to prepare the acetone dry powder (ADP), ii) several additional steps of sonication in the ADP preparation and extractions with dense sodium dodecyl sulfate and phenol, and iii) adding two stages of phenol extractions. Proteins were extracted from roots using this new protocol (Method B) and a protocol described in the literature for T. cacao leaves and meristems (Method A). Using these methods, we obtained a protein yield of about 0.7 and 2.5 mg per 1.0 g lyophilized root, and a total of 60 and 400 spots could be separated, respectively. Through Method B, it was possible to isolate high-quality protein and a high yield of roots from T. cacao for high-quality 2-DE gels. To demonstrate the quality of the extracted proteins from roots of T. cacao using Method B, several protein spots were cut from the 2-DE gels, analyzed by tandem mass spectrometry, and identified. Method B was further tested on Citrus roots, with a protein yield of about 2.7 mg per 1.0 g lyophilized root and 800 detected spots.

    Parkinson's disease is a progressive neurodegenerative movement disorder with the cardinal symptoms of bradykinesia, resting tremor, rigidity, and postural instability, which lead to abnormal movements and lack of activity, which in turn cause muscular damage. Even though studies have been carried out to elucidate the causative factors that lead to muscular damage in Parkinson's disease, apoptotic events that occur in the skeletal muscle and a therapeutical approach to culminate the muscular damage have not been extensively studied. Thus, this study evaluates the impact of rotenone-induced SNPc lesions on skeletal muscle apoptosis and the efficacy of an ethyl acetate extract of Morinda citrifolia in safeguarding the myocytes. Biochemical assays along with apoptotic markers studied by immunoblot and reverse transcription-polymerase chain reaction in the current study revealed that the supplementation of Morinda citrifolia significantly reverted alterations in both biochemical and histological parameters in rotenone-infused PD rats. Treatment with Morinda citrifolia also reduced the expression of pro-apoptotic proteins Bax, caspase-3 and caspase-9 and blocked the release of cytochrome c from mitochondria induced by rotenone. In addition, it augmented the expression of Bcl2 both transcriptionally and translationally. Thus, this preliminary study paves a way to show that the antioxidant and anti-apoptotic activities of Morinda citrifolia can be exploited to alleviate skeletal muscle damage induced by Parkinsonism.

    The aqueous extract of Desmodium gangeticum (L) DC (Fabaceae) (DG) was studied in isoproterenol induced myocardial infarcted (MI) rats for the hypocholesterolemic and antioxidant effect. After inducing MI by isoproterenol (35 mg/kg b wt. i.p.), the aqueous extract of Desmodium gangeticum root at a dose of 3 ml/100 g b wt. was orally administered daily for a period of 30 days in six rats. On induction of MI, the activities of creatinine phosphokinase (CPK), lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and serum glutamate oxaloacetate transaminase (SGOT) increased in myocardial tissue, hepatic tissue and serum. Pretreatment of DG to MI rats prevented the increase of these enzymes. The hypocholesterolemic effect of DG was assessed by the concentration of total cholesterol, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol and through the activities of 3-hydroxy 3-methyl glutaryl co-enzyme (HMG CoA) reductase and lecithin cholesterol acyl transferase (LCAT) in the myocardial tissue. The significant (P < 0.001) decrease in the concentration of thiobarbituric acid reactive substances (TBARS) and improved activities of glutathione reductase and catalase in the myocardial tissues of rats treated with DG suggest free radical scavenging activity of the extract.

    Traditional medicinal plants possess diverse active constituents for exerting their biological activities. Recently, the innovative applications of plant extracts have revealed their promise as 'green' reducing agents for the reduction of metal ions during the synthesis of metallic nanoparticles. Herein, we report the use of 70% ethanol extracts from Polygala tenuifolia roots as a 'green' reducing agent for the production of gold nanoparticles by reducing gold(III) chloride trihydrate. Gold nanoparticles were characterized using UV-Visible spectrophotometry, high-resolution transmission electron microscopy (HR-TEM), atomic force microscopy (AFM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). The gold nanoparticles had characteristic surface plasmon resonance bands at 535 nm. HR-TEM and AFM images revealed major spherical-shaped nanoparticles. The average diameter was measured to be 9.77±3.09 nm using HR-TEM images. The crystalline structure of the gold nanoparticles was confirmed through lattice fringes and circular spots within the selected area electron diffraction in the HR-TEM images along with the XRD peaks. The gold nanoparticles exhibited enhanced anticoagulant activity, as assessed by activated partial thromboplastin time. The current method is a straightforward, environmentally friendly, and inexpensive method for the production of gold nanoparticles using extracts from traditional medicinal plants.

    Full Text Available Sample preparation is a critical step in two-dimensional gel electrophoresis (2-DE of plant tissues. Here we describe a phenol/SDS procedure that, although greatly simplified, produced well-resolved and reproducible 2-DE profiles of protein extracts from soybean [Glycine max (L. Merril] roots. Extractions were made in three replicates using both the original and simplified procedure. To evaluate the quality of the extracted proteins, ten spots were randomly selected and identified by mass spectrometry (MS. The 2-DE gels were equally well resolved, with no streaks or smears, and no significant differences were observed in protein yield, reproducibility, resolution or number of spots. Mass spectra of the ten selected spots were compared with database entries and allowed high-quality identification of proteins. The simplified protocol described here presents considerable savings of time and reagents without compromising the quality of 2-DE protein profiles and compatibility with MS analysis, and may facilitate the progress of proteomics studies of legume-rhizobia interactions.

    Root aqueous extract of Lecaniodiscus cupanioides was evaluated for antimalarial activity and analyzed for its phytochemical constituents. Twenty-four (24) albino mice were infected by intraperitoneal injection of standard inoculum of chloroquine sensitive Plasmodium berghei (NK 65). The animals were randomly divided into 6 groups of 3 mice each. Group 1 served as the control while groups II-IV were orally administered 50, 150, and 250 mg/kg body weights of extract. Groups 5 and 6 received 1.75 and 5 mg/kg of artesunate and chloroquine, respectively. The results of the phytochemical analysis showed the presence of alkaloids (2.37%), saponin (0.336), tannin (0.012 per cent), phenol (0.008 per cent), and anthraquinone (0.002 per cent). There was 100 per cent parasite inhibition in the chloroquine group and 70 per cent in the 50 mg/kg body weight on day 12, respectively. The mean survival time (MST), for the control group was 14 days, artesunate 16 days, and chloroquine 30 days, while the groups that received 50 and 250 mg/kg body weight recorded similar MST of 17 days and the 150 mg/kg body weight group recorded 19 days. The results obtained indicated that the aqueous extract of Lecaniodiscus cupanioides may provide an alternative antimalarial.

    Guava (Psidium guajava L) is native to South America and exists as both wild and cultivated. Guava has been used as a source of food and raw materials for pharmaceuticals. The aim of this study was to determine bioactivity of methanol and water extracts from root and leaves of Kenyan guava landraces against selected pathogenic bacteria. Study samples were collected from Western and South Coast of Kenya. One hundred grams of leaf and root ground powders were used for sequential extraction using methanol and water. Extracts were evaporated and 0.2gms dissolved using the extraction solvent and tested against gram positive (Staphylococcus aureus, Bacillus subtilis) and negative bacteria (Escherichia coli). Data on inhibition zone was taken in mm and analyzed at 95% confidence interval. Extracts from Western region had significant inhibition compared to Coastal region. The two regions have different climatic conditions that result in these plants having different compounds even though they are the same species. Roots had higher inhibition compared to the leaves as they contain high levels of tannins compared to leaves. Water as an extracting solvent had higher inhibition than methanol as it is more polar and it absorbs more bioactive compounds. S. aureus was most inhibited followed by E. coli and B. subtilis respectively. There was no significant difference between the gram positive and negative bacteria. Remarkably, some methanol and water root extracts had significant inhibition against bacteria when compared to some commercial antibiotics used. Results of this study indicate that Kenyan guava roots from Western Kenya extracted with methanol and water have a potential to be used as a source of active compounds in treatment of gram positive and gram negative bacteria pathogens.

    Morinda citrifolia, has been reported to posses different biological activities and almost all parts of this have been studied phytochemically. However there are few studies on the seeds of fruit. The objective of present study was investigated the effect to Noni Seed Oil (NSO) on serum lipid levels in normolipidemic and hyperlipidemic induced mice. We find that administration of noni oil causes a reduction in total cholesterol and triglycerides levels in both models. However hypolipidemic effect is higher when hyperlipidemia is presented.

    Full Text Available Angelica Radix, the roots of the genus Angelica, has been used for more than 2,000 years as a traditional medicine in Eastern Asia. The Chinese Pharmacopoeia records more than 100 herbal formulae containing Angelica roots. There are two common sources of Angelica roots, Angelica sinensis from China and A. gigas from Korea. The two species of Angelica roots differ in their chemical compositions, pharmacological properties and clinical efficacy. 1H-NMR metabolic profiling has recently emerged as a promising quality control method for food and herbal chemistry. We explored the use of 1H-NMR metabolic profiling for the quality control of Angelica Radix. Unlike previous work, we performed the metabolic profiling on hot water extracts, so as to mimic the clinically relevant preparation method. Unsupervised principle component analyses of both the full spectral profile and a selection of targeted molecules revealed a clear differentiation of three types of Angelica roots. In addition, the levels of 13 common metabolites were measured. Statistically significant differences in the levels of glucose, fructose and threonine were found between different sources of Angelica. Ferulic acid, a marker commonly used to evaluate Angelica root, was detected in our samples, but the difference in ferulic acid levels between the samples was not statistically significant. Overall, we successfully applied 1H-NMR metabolic profiling with water extraction to discriminate all three sources of Angelica roots, and obtained quantitative information of many common metabolites.

    The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.

    Full Text Available Aims: In spite of folkloric use of the root of Carpolobia lutea as sexual stimulant in man, there has been limited scientific proof of its efficacy. This study evaluates efficacy of methanol extract of Carpolobia lutea root (MECLR on sexual activity of male rabbits. Methods: Twenty adult male rabbits were grouped into four of five rabbits each. Groups 1-4 were treated orally for 28 days with 2ml/kg 1% tween 20 (vehicle, 40mg/kg MECLR, 80mg/kg MECLR, and 0.5mg/kg sildenafil citrate respectively. Sexual activities of males from each group was assessed by cohabiting them with sexually receptive female at estrus on days 0,1,3 and 5 using digital camera mounted on mating arena. Serum testosterone and nitric oxide concentration of the corpora cavernosa homogenates were also determined. Results: MECLR caused a dose dependent significant increase in mount frequency, intromission frequency and ejaculatory latency, while it reduced mount latency, intromission latency and post ejaculatory latency (similar to sildenafil citrate when compared with the control. MECLR also caused a significant increase in nitric oxide concentration in corpora cavernosa but no change in serum testosterone concentration. Conclusions: Results suggest that MECLR enhances male sexual activity possibly by augmenting nitric oxide concentration. This study thus provides novel scientific rationale for the use of Carpolobia lutea in the management of penile erectile dysfunction and impaired libido.

    The objective of this study was to compare, ex vivo, the accuracy of three electronic apex locators (EALs), Root ZX II, Root ZX Mini and RomiApex A-15, in detecting the apical foramen (AF). Forty extracted single-Rooted human teeth with vital pulp were used in this study. After access preparation, the Root canal length of each tooth was measured by placing a #10 file until the tip was visible at the AF under a stereomicroscope. The teeth were subsequently embedded in an alginate model. In each Root canal, all three EALs were used to determine the working length, which was defined as the zero reading or equivalent. The distance between the file tip and AF was measured to an accuracy of 0.01 mm. Results were analyzed using analysis of variance and the Chi-squared test. Root ZX II, Root ZX Mini and RomiApex A-15 were accurate within 0.5 mm, 62.5, 56.2, 50% of the time. No significant differences were found between the three EALs (p > 0.05). Considering all EALs, the mean distance from the file tip to AF was 4.49 mm. The accuracy of the three EALs evaluated in this study was not statistically significantly different. The 'Apex' or '0.0' marks of the EALs do not indicate the AF itself, but just a position coronal 0.49 mm to the AF. Using a tolerance of ± 0.5 mm from the actual lengths, the ZX II yielded the most acceptable measurements.

    Full Text Available Alchornea cordifolia has been used traditionally for the induction of labour as an abortifacient. This study is aimed at verifying the folkloric use of the plant by investigating the effect of ethanolic extract of the root bark on the isolated stilboestrol pretreated uteri of non-pregnant female rats. The extract (1, 10, 50 g/l, oxytocin (4Χ10−5 to 8Χ10−3 g/l, acetylcholine (4Χ10−6 to 8Χ10−4 g/l, atropine (4Χ10−3 g/l, phenoxybenzamine (4Χ10−3 g/l, diphenhydramine(2Χ10−1 g/l, and verapamil (12Χ10−2 g/l were used. Log concentration response curves were plotted and EC 50 and Emax were obtained. One-way analysis of variance (ANOVA with Dunnet corrections using Graph pad Instat version 2.05a was used for statistical analysis. The extract produced dose-dependent contraction of the uterus. Its potency was less than that of oxytocin and acetylcholine (P<0.05, but the Emax showed no significant difference (P>0.05. The Emax values of the extract in the presence of all antagonists were significantly reduced (P<0.01. The EC 50 in the presence of atropine showed no significant increase (P>0.05; however, in the presence of phenoxybenzamine, the increase was significant (P<0.05. The presence of diphenhydramine and verapamil produced an inhibition such that the EC 50 was unattainable. A. cordifolia stimulates the uterus possibly by binding to alpha-adrenergic or histaminergic receptors or both. This indicates the existence of active principles in the plant, which may be responsible for some of the applications in traditional medicines as an abortifacient and in the induction of labour.

    Full Text Available Abstract Background This study aims to evaluate the antioxidant potential of the ethyl acetate extract of Desmodium gangeticum root for cardioprotection from ischemia reperfusion-induced oxidative stress. Methods The in vitro antioxidant potential of the extract was in terms of hydroxyl radical scavenging activity, lipid peroxide scavenging activity, nitric oxide scavenging activity and diphenylpicrylhydrazyl radical scavenging activity. The in vivo antioxidant potential of the extract was assessed in an isolated rat heart model. Results Free radicals were scavenged by the extract in a concentration-dependent manner within the range of the given concentrations in all models. Administration of the ethyl acetate extract of Desmodium gangeticum root (100 mg per kg body weight before global ischemia caused a significant improvement of cardiac function and a decrease in the release of lactate dehydrogenase in coronary effluent, as well as the level of malondialdehyde in myocardial tissues. Conclusion The ethyl acetate extract of Desmodium gangeticum root protects the myocardium against ischemia-reperfusion-induced damage in rats. The effects of the extract may be related to the inhibition of lipid peroxidation.

    In the present study, we obtained a dried burdock root extract (DBRE) rich in caffeoylquinic acids derivatives. We performed the chemical characterization of DBRE and explored its antihyperglycemic potential in both in vitro and in vivo experiments. Chemical analysis of DBRE using LC-MS and GC-MS revealed the presence of a great majority of dicaffeoylquinic acid derivatives (75.4%) of which 1,5-di-O-caffeoyl-4-O-maloylquinic acid represents 44% of the extract. In the in vitro experiments, DBRE is able to increase glucose uptake in cultured L6 myocytes and to decrease glucagon-induced glucose output from rat isolated hepatocytes together with a reduction of hepatic glucose 6-phosphatase activity. DBRE did not increase insulin secretion in the INS-1 pancreatic β-cell line. In vivo, DBRE improves glucose tolerance both after intraperitoneal and oral subchronic administration. In conclusion, our data demonstrate that DBRE constitutes an original set of caffeoylquinic acid derivatives displaying antihyperglycemic properties.

    Full Text Available Glycyrrhiza glabra, commonly known as licorice, is a popular herbal supplement used for the treatment of chronic inflammatory conditions and as sweetener in the food industry. This species contains a myriad of phytochemicals including the major saponin glycoside glycyrrhizin (G of Glycyrrhetinic acid (GA aglycone. In this study, 2D-ROESY NMR technique was successfully applied for distinguishing 18α and 18β glycyrrhetinic acid (GA. ROESY spectra acquired from G. glabra, Glycyrrhiza uralensis and Glycyrrhiza inflata crude extracts revealed the presence of G in its β-form. Anti-inflammatory activity of four Glycyrrhiza species, G, glabra, G. uralensis, G. inflata, and G. echinata roots was assessed against COX-1 inhibition revealing that phenolics rather than glycyrrhizin are biologically active in this assay. G. inflata exhibits a strong cytotoxic effect against PC3 and HT29 cells lines, whereas other species are inactive. This study presents an effective NMR method for G isomer assignment in licorice extracts that does not require any preliminary chromatography or any other purification step.

    Notoriously chemoresistant melanoma has become the most prevalent form of cancer for the 25-29 North American age demographic. Standard treatment after early detection involves surgical excision (recurrence is possible), and metastatic melanoma is refractory to immuno-, radio-, and most harmful chemotherapies. Various natural compounds have shown efficacy in killing different cancers, albeit not always specifically. In this study, we show that dandelion root extract (DRE) specifically and effectively induces apoptosis in human melanoma cells without inducing toxicity in noncancerous cells. Characteristic apoptotic morphology of nuclear condensation and phosphatidylserine flipping to the outer leaflet of the plasma membrane of A375 human melanoma cells was observed within 48 hours. DRE-induced apoptosis activates caspase-8 in A375 cells early on, demonstrating employment of an extrinsic apoptotic pathway to kill A375 cells. Reactive Oxygen Species (ROS) generated from DRE-treated isolated mitochondria indicates that natural compounds in DRE can also directly target mitochondria. Interestingly, the relatively resistant G361 human melanoma cell line responded to DRE when combined with the metabolism interfering antitype II diabetic drug metformin. Therefore, treatment with this common, yet potent extract of natural compounds has proven novel in specifically inducing apoptosis in chemoresistant melanoma, without toxicity to healthy cells.

    Metastasized lung and liver cancers cause over 2 million deaths annually, and are amongst the top killer cancers worldwide. Morinda citrifolia (Noni) leaves are traditionally consumed as vegetables in the tropics. The macro and micro effects of M. citrifolia (Noni) leaves on metastasized lung cancer development in vitro and in vivo were compared with the FDA-approved anti-cancer drug Erlotinib. The extract inhibited the proliferation and induced apoptosis in A549 cells (IC50 = 23.47 μg/mL) and mouse Lewis (LL2) lung carcinoma cells (IC50 = 5.50 μg/mL) in vitro, arrested cancer cell cycle at G0/G1 phases and significantly increased caspase-3/-8 without changing caspase-9 levels. The extract showed no toxicity on normal MRC5 lung cells. Non-small-cell lung cancer (NSCLC) A549-induced BALB/c mice were fed with 150 and 300 mg/kg M. citrifolia leaf extract and compared with Erlotinib (50 mg/kg body weight) for 21 days. It significantly increased the pro-apoptotic TRP53 genes, downregulated the pro-tumourigenesis genes (BIRC5, JAK2/STAT3/STAT5A) in the mice tumours, significantly increased the anti-inflammatory IL4, IL10 and NR3C1 expression in the metastasized lung and hepatic cancer tissues and enhanced the NFE2L2-dependent antioxidant responses against oxidative injuries. The extract elevated serum neutrophils and reduced the red blood cells, haemoglobin, corpuscular volume and cell haemoglobin concentration in the lung cancer-induced mammal. It suppressed inflammation and oedema, and upregulated the endogenous antioxidant responses and apoptotic genes to suppress the cancer. The 300 mg/kg extract was more effective than the 50 mg/kg Erlotinib for most of the parameters measured.

    Full Text Available We screened the aqueous and methanol leaf and root extracts of Anthocleista djalonensis, Diospyros mespiliformis, and their combinations for possible anti-mycobacterial activities using Mycobacterium smegmatis as a surrogate screen. These plants are reputed among folk practices as potent remedy in the management of tuberculosis and leprosy cases. In the sensitivity screening study, only the methanol extracts of A. djalonensis and D. mespiliformis showed anti-mycobacterial activity, while the aqueous extracts exhibited no inhibitory activity on M. smegmatis. The minimum inhibitory concentration (MIC of the methanol leaf and root extract of A. djalonensis against M. smegmatis were 125 μg/ml. The MIC of the methanol leaf and root extracts of D. mespiliformis is 167 and 250 μg/ml, respectively. In the interaction studies, four out of nine decimal combinations of the two medicinal plant extracts exhibited synergism with fractional inhibitory concentration indices < 1 and a negative activity index values. The 8:2 ratio of D. mespiliformis and A. djalonensis exhibited the greatest degree of antimycobacterial synergy against M. smegmatis. The result of this study supports the claims of efficacy reported in the folk use of these plants in mycobacterial infection and the plants could therefore be investigated further and harnessed as potent antimycobacterial agents.

    Full Text Available Berberis aetnensis C. Presl (Berberidaceae is a bushy-spiny shrub common on Mount Etna (Sicily. We demonstrated that the alkaloid extract of roots of B. aetnensis C. Presl contains prevalently berberine and berbamine, possesses antimicrobial properties, and was able to counteract the upregulation evoked by glutamate of tissue transglutaminase in primary rat astroglial cell cultures. Until now, there are no reports regarding antioxidant properties of B. aetnensis C. Presl collected in Sicily. Air-dried, powdered roots of B. aetnensis C. Presl were extracted, identified, and quantified by HPLC. We assessed in cellular free system its effect on superoxide anion, radicals scavenging activity of antioxidants against free radicals like the 1,1-diphenyl-2-picrylhydrazyl radical, and the inhibition of xanthine oxidase activity. In primary rat astroglial cell cultures, exposed to glutamate, we evaluated the effect of the extract on glutathione levels and on intracellular production of reactive oxygen species generated by glutamate. The alkaloid extract of B. aetnensis C. Presl inhibited superoxide anion, restored to control values, the decrease of GSH levels, and the production of reactive oxygen species. Potent antioxidant activities of the alkaloid extract of roots of B. aetnensis C. Presl may be one of the mechanisms by which the extract is effective against health disorders associated to oxidative stress.

    Oral pre-treatment with ethanolic extract of the roots of C. carandas (ERCC; 100, 200 and 400 mg/kg, po) showed significant hepatoprotective activity against CCl4 and paracetamol induced hepatotoxicity by decreasing the activities of serum marker enzymes, bilirubin and lipid peroxidation, and significant increase in the levels of uric acid, glutathione, super oxide dismutase, catalase and protein in a dose dependent manner, which was confirmed by the decrease in the total weight of the liver and histopathological examination. Data also showed that ERCC possessed strong antioxidant activity, which may probably lead to the promising hepatoprotective activities of C. carandas root extract. These findings therefore supported the traditional belief on hepatoprotective effect of the roots of C. carandas.

    Horseradish (Armoracia rusticana) is a perennial crop and its root is used in condiments. Traditionally, horseradish root is used to treat bacterial infections of the respiratory tract and urinary bladder. The antiphlogistic activity, determined in activated primary human peripheral blood mononuclear cells (PBMC), was evaluated for an aqueous extract and its subfractions, separated by HPLC. Compound analysis was done by UHPLC-QToF/MS and GC-MS. The aqueous extract concentration-dependently inhibited the anti-inflammatory response to lipopolysaccharide (LPS) in terms of TNF-α release at ≥37 μg/mL. Further, the cyclooxygenase as well as lipoxygenase pathway was blocked by the extract as demonstrated by inhibition of COX-2 protein expression and PGE2 synthesis at ≥4 μg/mL and leukotriene LTB4 release. Mechanistic studies revealed that inhibition of ERK1/2 and c-Jun activation preceded COX-2 suppression upon plant extract treatment in the presence of LPS. Chemical analysis identified target compounds with a medium polarity as relevant for the observed bioactivity. Importantly, allyl isothiocyanate, which is quite well known for its anti-inflammatory capacity and as the principal pungent constituent in horseradish roots, was not relevant for the observations. The results suggest that horseradish root exerts an antiphlogistic activity in human immune cells by regulation of the COX and LOX pathway via MAPK signalling. PMID:28182113

  12. An investigation into the kinetics and mechanism of the removal of cyanobacteria by extract of Ephedra equisetina root.

    Directory of Open Access Journals (Sweden)

    Rong Yan

    Full Text Available An aqueous extract of Ephedra equisetina root was found to induce cyanobacterial cell death. The extract displayed no negative effects on the fish populations but instead, improved the habitat conditions for the growth of macrophytes, zooplankton and bacteria because the inhibiting effects of the extracts on cyanobacteria helped clear up the water column. The removal kinetics of cyanobacteria by E. equisetina extract appears to be a first order process with the rate constant being extract-dose-dependent. Compounds including the flavonoids found in E. equisetina root kill the cyanobacteria in vitro at a dose of 5.0 µg extract per 100 mL water or above. The extract constituents act to disrupt the thylakoid membrane, interrupt the electronic transport, decrease the effective quantum yield, and eventually lead to the failure of photosynthesis in Microcystis aeruginosa. This study presents an easily-deployed, natural and promising approach for controlling cyanobacterial blooms as an emergency measure, and also provides insight into the dynamics and mechanism of the extract consisting of multiple compounds synergistically removing algae.

    Fresh first year roots from Dipsacus sylvestris HUDS. were extracted with 70% ethanol, ethyl acetate as well as dichloromethane. Extracts were solubilized in water (lipophilic extracts with addition of polysorbate 80) and tested for their activity against Borrelia burgdorferi sensu stricto in vitro during an eight-day period using amoxicillin as standard. The hydroethanolic extract showed no growth inhibition whereas significant growth inhibiting activity could be shown in the two less polar fractions for the first time. Strongest inhibition was found in the ethyl acetate extract. The effect of polysorbate 80 on bacterial growth was examined and found to be negligible. As the nature of bioactive constituents has not been clarified yet, a micellar electrokinetic capillary chromatography fingerprint analysis for a methanolic extract was applied including loganin, chlorogenic acid, cantleyoside and caffeic acid as marker substances.

    Full Text Available This study was designed to determine the antiproliferative activity of three extracts (alcoholic, hydro-aqueous and aqueous and their fractions from the root part of Calotropis procera using human oral (KB and central nervous system (SNB-78 cancer cell lines as a model system. KB and SNB-78 cells were cultured in the presence of extracts and fractions at various concentrations (10, 30 and100 µg/ml for 48 h, and the percentage of cell viability was evaluated by the sulforhodamine-B (SRB assay. Our result indicates that out of the three extracts of C. procera (root, alcoholic extract had shown greater potential for growth inhibition followed by hydro-aqueous extract at three different concentration of 10 µg/ml, 30 µg/ml and 100 µg/ml in a dose-dependent manner, whereas aqueous extract was found to be least active against both oral and CNS human cancer lines. On evaluation of the fractions prepared from alcoholic and hydro-aqueous extracts, it was observed that chloroform fraction from alcoholic extract was antiproliferative for oral (KB cancer cell line and n-butanol fraction from alcoholic extract was antiproliferative for CNS cancer cell line than remaining fractions at three different concentration of 10 µg/ml, 30 µg/ml, 100 µg/ml in a dose-dependent manner. Thus, our result indicates that the root part of C. procera possess in vitro cytotoxicity against oral and CNS human cancer cell lines. Further investigations are required to obtain the clinically important lead molecules for the drug development.

    Full Text Available Introduction: According to the WHO, 70–80% population in developing countries still relies on nonconventional medicine mainly of herbal origin. Even in developed countries, use of herbal medicine is growing each year. Pain is an unpleasant feeling often caused by intense or damaging stimuli. Traditionally, different plant parts of Ficus benghalensis are claimed to have several analgesic properties. Few scientific evidences support these uses. Interestingly, still others contradict these uses. It was shocking to find very scarce scientific studies trying to solve the mystery. Materials and Methods: It was a quantitative experimental study in Swiss albino mice of either sex. Sample size was calculated using free sample size calculating software G*Power version 3.1.9.2. Hot-plate test and tail-flick test were central antinociceptive paradigms. Writhing test was peripheral model for pain. Test drugs were aqueous root extracts of F. benghalensis at 100 mg/kg and 200 mg/kg mouse weight prepared by Soxhlet method. Suitable negative and positive controls were used. The experimental results were represented as mean ± standard deviation statistical level of significance was set at P < 0.05. For calculation, parametric test - one-way analysis of variance (ANOVA or nonparametric test - Mann–Whitney U-test was appropriately used. Results: Hot-plate reaction time at 100 mg/kg (13.64 ± 1.30 s and 200 mg/kg (10.32 ± 2.23 s were nonsignificant (P = 0.425 and P = 0.498, respectively compared to negative control (11.87 ± 1.92 s. One-way ANOVA revealed nonsignificant (P = 0.178 between-group comparison in mean tail-flick reaction time.

    Full Text Available The Plumbago genus belongs to the Plumbaginaceae family and it is known due to its variety of biological uses, most of them attributed to the presence of naphthoquinones. Plumbagin is a naturally occurring naphthoquinone that can be obtained from roots of Plumbago scandens L. In order to find out the better technique for plumbagin extraction, were applied: static maceration, dynamic maceration, with assistance of ultrasonic waves and in Soxhlet apparatus. Four compounds were qualitatively detected in all extracts: the naphthoquinones plumbagin and epi-isoshinanolone, palmitic acid and sitosterol. Plumbagin was always the major component in all analyzed extracts and it was quantitatively determined by gas chromatograph coupled with mass spectrometer. Soxhlet was the most efficient extraction technique however, prolonged heating time promoted plumbagin degradation.O gênero Plumbago pertence à família Plumbaginaceae e apresenta uma variedade de atividades biológicas, a maioria atribuída à presença de naftoquinonas. Plumbagina é uma naftoquinona natural que pode ser obtida a partir de raízes de Plumbago scandens L. Na tentativa de descobrir a melhor técnica de extração dessa substância foram usadas, maceração estática, maceração dinâmica, extração com auxílio de ultrassom e extração em Soxhlet. Quatro substâncias foram detectadas qualitativamente: as naftoquinonas plumbagina e epi-isoshinanolona, o ácido palmítico e o sitosterol. Plumbagina foi sempre o componente majoritário em todos os extratos analisados e sua determinação quantitativa foi realizada através de cromatografia com fase gasosa acoplada à espectrometria de massas. A extração em Soxhlet foi a técnica mais eficiente para obtenção de plumbagina, entretanto a longa exposição a temperaturas elevadas favoreceu a degradação da plumbagina.

    Compost extracts are novel organic amendments, typically applied to suppress soil-borne diseases. This research evaluated the phytotoxicity of compost extracts and analyzed their ability to inhibit pathogenic fungal growth and reduce root-knot nematodes. The physical, chemical and biological characteristics of extracts from a pig manure and straw compost were analyzed. Three types of extracts were tested: direct extracts of compost (DEC), aerated fermentation extracts of compost (AFEC) and non-aerated fermentation extracts of compost (NAFEC). All compost extracts showed low phytotoxicity against lettuce and cress, but AFEC and NAFEC were more phytotoxic than DEC. All compost extracts significantly inhibited pathogenic fungal growth except for the fungus Rhizoctonia solania AG4. For two seasons, tomato root biomass of three compost extracts was 1.25-5.67 times greater than CK (water control), and AFEC and NAFEC showed the best tomato root growth promotion. The reduction ratio of root egg mass and density of soil nematodes were 34.51-87.77% and 30.92-51.37%, when applied with three compost extracts. The microbial population in compost extracts was considered to be the most significant factor of inhibition pathogenic fungal growth. No markedly correlations among bacterial community diversity, the inhibition of pathogenic fungal growth and the reduction of root-knot nematodes were observed. This information adds to the understanding of the growth-promoting and suppression effects of compost extracts and will help to enhance crop production.

    Objective:To evaluate pharmacological mimetic action of herbal extractDesmodium gangeticum (DG) roots on ischemia reperfusion injury.Methods:With the help of Langendroff perfusion technique, ischemic post condition (POC) mimetic action of DG methanol root extract was evaluated and compared by using standard drugs that acts as muscarinic receptor agonist and antagonist, namely acetylcholine (Ach) and atropine (Atr) respectively in an isolated rat heart. Results:The physiological parameters like left ventricular developed pressure, end diastolic pressure and working index of isolated rat heart showed significant recovery in DG root extract administrated rat heart, similar to the recovery by POC. Kymogram results showed muscarinic receptor agonist like action for DG methanol root extract, confirmed in rat heart by muscarnic receptor agonist (acetylcholine) and anatoginst (atropine). Administration of DG root extract prior to reperfusion showed better antioxidant status in myocardial tissue homogenate and mitochondrial, complemented by the levels of cardiac specific marker proteins in myocardial tissue and perfusate. Even though DG methanol root extract mimics its action similar to that of Ach, the myocardial protection mediated by the extract was superior to Ach, due to the presence of antioxidants in the crude extract.Conclusions: DG methanol root extract provides myocardial protection towards IRI by stimulating muscarinic receptors.

    Rhaponticum carthamoides has a long tradition of use in Siberian folk medicine. The roots and rhizomes of this species are used in various dietary supplements or nutraceutical preparations to increase energy level or eliminate physical weakness. This is the first report to reveal the protective and DNA repair stimulating abilities of R. carthamoides root extracts in Chinese hamster ovary (CHO) cells exposed to an oxidative agent. Both transformed root extract (TR extract) and extract of soil-grown plant roots (NR extract) may be responsible for stimulating CHO cells to repair oxidatively induced DNA damage, but CHO cells stimulated with extract from the transformed roots demonstrated significantly stronger properties than cells treated with the soil-grown plant root extract. These differences in biological activity may be attributed to the differences in the content of phenolic compounds in these root extracts. Preincubation of the CHO cells with TR and NR extracts showed an increase in gene expression and protein levels of catalase (CAT) and superoxide dismutase (SOD2). R. carthamoides may possess antioxidant properties that protect CHO cells against oxidative stress. PMID:27034736

    The effects of grape-tobacco intercropping patterns on populations of grape phyl oxera, Daktulosphaira vitifoliae Fitch, as wel as on the growth and development of the infested vines were evaluated in the ifeld and the impact of an aqueous tobacco root extract on grape phyl oxera was evaluated using a laboratory bioassay. The aqueous tobacco root extract exhibited biological activity against this pest. The egg mortality, nymph mortality, development period, life span and female fecundity were signiifcantly affected. In the ifeld trial, grape phyl oxera populations were clearly lower as compared to the monoculture pattern. However, the rates of newly developed roots and newly infested grape roots were signiifcantly higher and lower, in intercropping patterns than in the vine monoculture, respectively. The grape phyl oxera population number on the grape roots decreased each year, and the vine trees gradual y renewed upon continuous intercropping with tobacco over three years. These results conifrmed that intercropping grapes with tobacco can effectively control grape phyl oxera in an infested vineyard. The results also indicated that additional crops could be intercropped with grapes and are effective against grape phyl oxera, which should be explored as an integrated approach for control ing the pest.

    Arctium lappa L. is used in folk medicine as a diuretic, depurative and digestive stimulant and in dermatological conditions. The objective of this study was to evaluate the effect and the possible mechanisms involved in the gastroprotective effects of a chloroform extract (CE) of the roots from A. lappa and its fractions. Oral pretreatment with CE (10, 30 and 100 mg kg(-1)) significantly reduced gastric lesions induced by ethanol by 61%, 70% and 76%, respectively. Oral administration of CE (100 mg kg(-1) per day for 7 days) reduced the chronic gastric ulceration induced by acetic acid by 52%. Intraduodenal CE (100, 300 and 600 mg kg(-1)) reduced the total acidity of gastric secretion by 22%, 22% and 33%, respectively, while i.p. administration (10, 30 and 100 mg kg(-1)) inhibited total acidity by 50%, 60% and 67%, respectively. In-vitro, CE inhibited H+, K+ -ATPase activity with an EC50 of 53 microgmL(-1) and fraction A (30 and 100 microgmL(-1)) reduced this by 48% and 89%, respectively. CE had no effect on gastrointestinal motility. CE (250 microgmL(-1)) and fraction B (100 and 250 microgmL(-1)) had free-radical scavenging ability, inhibiting 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical activity by 50%, 20% and 55%, respectively. Collectively, the results show that the CE protects animals from gastric lesions by reducing gastric acid secretion via inhibition of gastric H+, K+ -ATPase.

    Croton membranaceus Müll.Arg. (Euphorbiaceae) is used for benign prostate hyperplasia (BPH) treatment. The study aimed at investigating organs that the aqueous root extracts of C. membranaceus (CMARE) target, which is absent in literature. Twenty-four male Sprague-Dawley rats (100-140 g) were randomly divided into 4 groups. Group 1, the control group received distilled water. Groups 2, 3 and 4 received 30, 150 and 300 mg kg(-1) b.wt CMARE respectively (oral gavage). Rats fed 90 days the standard chow diet ad libitum. Upon sacrifice, major organs were histologically examined and serum prostate-specific antigen (PSA) biochemically determined. Only the prostate was abnormal. Histologically, H&E staining revealed thickness and infoldings of the epithelial cells shrinking with increasing dose. The 30 mg kg(-1) group showed low columnar or flattened epithelium cells, whereas the columnar epithelium infoldings of the 150 mg kg(-1) b.wt and 300 mg kg(-1) b.wt groups were virtually nonexistent. The acini of the control, 30 mg kg(-1) b.wt group and the 150 mg kg(-1) b.wt groups showed clear pinkish secretion. However, secretion of the high-dose group appeared light pink in colour and the stroma cells appeared much darker than all the treated and control group. C. membranaceus targets the prostate with significant PSA reduction (P < 0.01).

    Opuntia ficus indica f. inermis methanolic root extract (ORE) was investigated for phenolic and flavonoids contents, in vitro evaluated for DPPH radical scavenging activity, reducing power and in vivo tested for its gastro-protective ability against 80% ethanol induced ulcer in rats. Phytochemical test of ORE were positive for phenolic and flavonoid contents. DPPH radical scavenging activity and reducing power of ORE showed an EC(50) of 118.65±2.51 μg/ml and 300 μg/ml respectively. In vivo the pre-treatment of rats with ranitidine (50 mg/kg) and 200, 400, and 800 mg/kg doses of ORE significantly (p<0.05) reduced the 80% ethanol induced-ulcer lesion, with a rate of 82.68%, 49.21%, 83.13%, and 92.59% respectively, and prevented the depletion of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), total glutathione (GSH), and inhibited the increase of myeloperoxidase (MPO) and malondialdehyde (MDA) in rat stomach tissues when compared with ethanol group. Also pre-treatment with ORE marked a dose-dependent attenuation of histopathology changes induced by ethanol. Phenolic and flavonoids wealth, radical scavenging activity, and reducing power, have been implicated for antiulcer property of ORE.

    Although Eurycoma longifolia has been studied for erectile function, the blood pressure- (BP-) lowering effect has yet to be verified. Hence, this study aims at investigating the BP-lowering properties of the plant with a view to develop an antihypertensive agent that could also preserve erectile function. Ethanolic root extract was partitioned by hexane, dichloromethane (DCM), ethyl acetate, butanol, and water. The DCM fraction, found to be potent in relaxing phenylephrine- (PE-) precontracted rat aortic rings, was further purified by column chromatography. Subfraction DCM-II, being the most active in relaxing aortae, was studied for effects on the renin-angiotensin and kallikrein-kinin systems in aortic rings. The effect of DCM-II on angiotensin-converting enzyme (ACE) activity was also evaluated in vitro. Results showed that DCM-II reduced (p < 0.05) the contractions evoked by angiotensin I and angiotensin II (Ang II). In PE-precontracted rings treated with DCM-II, the Ang II-induced contraction was attenuated (p < 0.05) while bradykinin- (BK-) induced relaxation enhanced (p < 0.001). In vitro, DCM-II inhibited (p < 0.001) the activity of ACE. These data demonstrate that the vasodilatory effect of DCM-II appears to be mediated via inhibition of Ang II type 1 receptor and ACE as well as enhancement of Ang II type 2 receptor activation and BK activity.

    Full Text Available Summary: The present study explored the anti-inflammatory potential of aqueous root extract of Strophanthus hispidus (SPH DC (Apocynaceae in rodents, using standard laboratory models. Doses of 50, 100, 500 and 1000 mg/kg of aqueous SPH were administered orally in carrageenan-induced rat hind paw oedema, xylene-induced ear oedema in mice, and formalin-induced mice hind paw oedema (sub-acute 6 days, using indomethacin (10 mg/kg, dexamethasone 1 mg/kg and acetylsalicylic acid (Aspirin, 100 mg/kg respectively as standard drugs. The study further explored the effect of the herbal drug on some inflammatory mediators-histamine, serotonin and prostaglandin, using only the highest dose of SPH. Results obtained showed that the extract exerted a dose-dependent and significant (p<0.05 anti-inflammatory activity, which compared favourably with the positive control.  Significant inhibitions of mediators were also recorded; however, the least inhibition (42.8 % was produced in the serotonin model. Phytochemical analysis indicated the presence of flavonoids, cardiac glycosides, tannins, and anthraquinones.  It is also noteworthy that zinc, copper, manganese, lead, and chromium were the elemental constituents in the aqueous extract of SPH, some of which have been reported to possess anti-inflammatory property. While 2 g/kg of SPH administered orally did not produce any mortality, the median lethal dose by i.p route was 39.81 mg/kg, and it is thought that the lead contribute to the toxicity recorded. The pH of the herbal drug was 6.7. Our findings substantiate the local use of SPH in the treatment of acute and sub-acute inflammatory conditions, while it also suggests some possible pathways for its anti-inflammatory activity.  Lastly, since the herbal drug is liable to producing toxic effects, it must be used with caution. Industrial relevance: Herbal remedies continue to serve as an important source of conventional therapies for diverse disease conditions

    The aim of this study was to assess the ability of a traditional Chinese medicinal ginger root extract (GRE) to prevent behavioral dysfunction in the Alzheimer disease (AD) rat model. Rat AD models were established by an operation (OP) in which rats were treated with a one-time intra-cerebroventricuIar injection of amyloid β-protein (Aβ) and continuous gavage of aluminum chloride every day for 4 weeks. GRE was administered intra-gastrically to rats. After 35 days, learning and memory were assessed in all of the rats. Brain sections were processed for immunohistochemistry and Hematoxylin & Eosin (H&E) and Nissl staining. The latency to show significant memory deficits was shorter in the group that received OP with a high dose of GRE (HG)(OP+HG) than in the groups that received OP with a low or moderate dose of GRE (LG, MG)(OP+LG, OP+MG) (p<0.05). The expression of superoxide dismutase (SOD) and catalase (CAT) in the OP+MG and OP+LG groups was up-regulated compared to the OP+HG groups (p<0.05). The rats in the OP+HG groups had lower levels of nuclear factor-κB (NF-κB), interleukin-1β (IL-1β), and malondialdehyde (MDA) expression than the rats in the OP+MG and OP+LG groups (p<0.05). This experiment demonstrates that the administration of GRE reverses behavioral dysfunction and prevents AD-like symptoms in our rat model.

    Asparagus racemosus root extracts (AR) have been reported to possess a variety of pharmacological properties. The aim of the present study was to develop liposomes of AR and to assess their physicochemical characteristics and anti-inflammatory activity in the monocytic leukemia cell line THP-1. Liposomes containing various ratios of AR to lipid and a phosphatidylcholine to cholesterol molar ratio of 7:3 were prepared by thin-film hydration (TF), reverse-phase evaporation (REV) and polyol dilution (PD). The results showed that AR liposomes prepared by TF had a multilamellar structure and a large size, whereas those prepared by REV and PD were oligolamellar in structure, and of a smaller size. The particle sizes and zeta potentials of the liposomes ranged from 196.5 to 456.6 nm and from −4.34 to −18.94 mV, respectively. The AR to lipid ratio was shown to have no significant influence on particle size, while the zeta potential generally increased with increasing AR to lipid ratio. The highest entrapment efficiency values were detected in liposomes with an AR to lipid ratio of 1:5, and for liposomes prepared by TF, REV and PD methods, the entrapment efficiencies were 55.71±2.04, 56.21±3.59 and 67.68±1.37%, respectively. AR was found to exert no toxicity on THP-1 cells. The maximum anti-inflammatory activities of AR and AR liposomes, evaluated in terms of the percentage inhibition of tumor necrosis factor-α in THP-1 cells, were ~52% at a concentration of 1 µg/ml. It can be concluded from the present study that AR liposomes have the potential to be used a formulation for topical and/or transdermal drug delivery to provide anti-inflammatory activity.

Objective: In this study, clinical evaluation of Boerhavia diffusa root extract was carried out in CRF in dogs in comparison with standard enalapril. Materials and Methods: A total of 20 dogs of mixed breeds suffering from CRF from 1 to 2 months were divided into two groups (n = 10 and treated as follows: Group I - Enalapril at 0.5 mg/kg p.o. once daily for 90 days + amoxicillin and cloxacillin at 25 mg/kg i.m. once daily for 1-week; Group II - B. diffusa root extract at 500 mg p.o per dog daily for 90 days. Both groups were maintained on a supportive fluid therapy. The data were analyzed using paired t-test and one-way ANOVA followed by Dunnett's post-hoc test. Results: CRF caused a significant (P < 0.05 increase in systolic and diastolic blood pressure, serum creatinine, urea nitrogen, sodium, potassium, phosphorus, urinary protein, alkaline phosphatase (ALP, and glutamyl transferase (GGT. A significant (P < 0.05 decrease in hemoglobin and total erythrocyte count (TEC was also observed. Nephrosonography revealed indistinct corticomedullary junction, altered renal architecture, hyper-echoic cortex, medulla, and sunken kidneys. Both the treatments significantly (P < 0.05 reduced systolic and diastolic blood pressure by day 30. Serum Creatinine, urea nitrogen, phosphorus, urinary protein, ALP, and GGT showed significant (P < 0.05 reduction by day 60 in both the treatments. However, potassium levels were normalized only by B. diffusa root extract treatment by day 30. Both the treatments failed to show a significant improvement in nephrosonographic picture even after 90 days posttreatment. Conclusions: In conclusion, the efficacy of B. diffusa root extract was comparable to standard enalapril treatment of CRF in dogs.

    Full Text Available The chemical composition of the ethanol extracts of chicory root, peel, seed and leaf has been determined, in particular their inulin and phenolic fractions. The root and peel extracts were characterized by large mass fractions of inulin (60.1 and 46.8 g per 100 g of fresh mass, respectively, predominantly with degree of polymerization in the range from 3 to 10, while phenolics, determined as caffeoylquinic acids, made up 0.5 and 1.7 g per 100 g of fresh mass, respectively. The leaf and seed extracts had decidedly lower mass fractions of inulin (1.7 and 3.2 g per 100 g of fresh mass, respectively and higher mass fractions of phenolics (9.6 and 4.22 g per 100 g of fresh mass, respectively recognized as caffeoylquinic acids, chicoric acid and quercetin glucuronide. The biological properties of a non-inulin fraction from each extract were determined on Wistar rats fed with diets rich in fructose and saturated fat, as a model of metabolic changes related to westernization of human eating habits. The diets contained the same amount of inulin (6 % with various phenolic fractions. Some changes were noted in the microbial enzymatic activity of the caecum after feeding for 4 weeks with the diet containing the highest mass fraction of phenolics (0.208 %, derived from the mixture of peel and seed extracts (decreased activity of β-galactosidase and β-glucuronidase, as well as with the diet containing leaf extract (decreased β-glucuronidase activity. All the diets showed no essential influence on the caecal concentration and profile of short-chain fatty acids, except acetate, whose concentration decreased significantly in rats fed with the diet enriched with root extract. The addition of peel and leaf extracts to the fructose diets significantly increased the serum antioxidant capacity of lipophilic substances. The study indicates that parts of chicory and its byproducts might be a source of valuable compounds to improve the physiological activity of

    Protective effects of peony root extract and its components on neuron damage in the CA1 area of the hippocampus induced by the cobalt focus epilepsy model were examined. Neuron damage in the CA1 area of the hippocampus and frequent spike discharges induced by application of metallic cobalt to the cerebral cortex of rats were completely prevented when peony root extract was continuously administered orally at 1 g/kg/day for 30 days prior to cobalt application. Component crude gallotannin fraction showed marked but incomplete protective action. A combination of crude gallotannin fraction and paeoniflorin showed complete protective action in the same way as peony root extract against neuron damage although use of paeoniflorin alone had no effect. These findings together with our previous reports indicate that peony root extract and its component, gallotannin, have excellent protective effects on neuron damage in addition to anticonvulsant action by prior oral administration.

    Compounds with antioxidant activity may protect different elements of blood from damaging effects of oxidative stress. The present in vitro study was designed to examine the antioxidant activity of methanolic extracts from leaves and roots of R. glutinosa plants against damages induced by oxidative stress. Oxidative stress was stimulated in human plasma and human blood platelet samples by the strong biological oxidant--hydrogen peroxide (H2O2) or H2O2/Fe (the donor of hydroxyl radicals). In experimental trials, the level of biomarker of lipid peroxidation--TBARS was significantly decreased by the action of methanolic extracts from R. glutinosa leaves. Therefore, it seems that the methanolic extract from leaves of the plants may be a new source of bioactive antioxidant natural compounds. It may be also an active pharmacological agent or a food supplement for healthy subjects and for people with different diseases (cardiovascular diseases and cancer) induced by oxidative stress.

    Full Text Available Reactive oxygen species (ROS and free radical species have been implicated in initiating or accompanying many diseases in living organisms; there is thus, a continual need for antioxidants molecules to inactivate ROS/free radicals. Many studies of plants crude extracts have demonstrated free-radical scavenging and antioxidant action. Salacia species have long been used, in several countries, as traditional medicines against certain diseases and for their anti-inflammatory properties. In this study, Salacia campestris Walp (Hippocrateaceae root bark ethanol extract (ScEtOH was assessed for its ability to scavenge free radicals and reactive oxygen species; the results were expressed as percentage inhibition of the active species. ScEtOH was efficient against studied species: DPPH radical (obtained inhibition = 30%, ABTS•+ (IC50 = 1.8±0.8 μg/mL, HOCl (IC50 = 1.7 ± 0.1 μg/mL, O2•- (obtained inhibition = 32%, and NO• (obtained inhibition = 18 %. Peroxidase activity inhibition was evaluated through the guaiacol oxidation reaction catalyzed by hemin, HRP and myeloperoxidase (MPO; data showed that ScEtOH at 10 μg/mL led to 54 and 51% of inhibition, respectively, for the hemin and HRP systems. In the MPO system, ScEtOH promoted a 50% inhibition at 8.9 μg/mL, whereas quercetin, a powerful MPO inhibitor, inhibited this system at 1.35 μg/mL.Espécies reativas do oxigênio (ERO e radicais livres estão relacionados ao início ou à exacerbação de muitas doenças em organismos vivos; existindo portanto uma necessidade contínua por moléculas antioxidantes que inativem as ERO e radicais livres.

    Ultrasound-assisted extraction was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of ginsenosides (saponins) from various types of ginseng. The ginseng samples were extracted with different solvents, under either direct sonication by an ultrasound probe horn or indirect sonication in an ultrasound cleaning bath. The ultrasonic extraction was compared with the conventional method of refluxing boiling solvents in a soxhlet extractor, on the yields of both the total saponin isolated by thin-layer chromatography and the individual ginsenosides by high performance liquid chromatography. It was found that the sonication-assisted extraction of ginseng saponins was about three times faster than the traditional extraction method. The ultrasonic extraction was not only more efficient but also convenient for the recovery and purification of the active ingredients of plant materials. In addition, the sonication-assisted extraction can be carried out at lower temperatures which are favorable for the thermally unstable compounds.

    2015-01-01

    We determined the in vitro antioxidant activity of methanolic extracts from the shoots and roots of Scutellaria species (S. altissima and S. alpina) against the action of strong oxidants: hydrogen peroxide (H2O2) and H2O2+Fe(2+) (donor of hydroxyl radicals) on plasma proteins and lipids. Lipid peroxidation in human plasma was measured by the level of thiobarbituric acid reactive species (TBARS). Protein oxidation was measured by quantitation of thiol group. We observed that the extracts (5-50 µg ml(-1)) containing phenolic compounds from both Scutellaria species distinctly reduced oxidation of lipids and proteins in human plasma treated with H2O2. These results also indicated that the extracts have a protective effect against oxidative damage to the human plasma lipids and proteins by induced hydroxyl radical. The main components of the plant materials analysed were flavonoids, present as aglycones (luteolin) or glycosides (cynaroside, baicalin, wogonoside). In all of the extracts, the phenylethanoid verbascoside was also found. The properties of the tested plant extracts were also compared with the action of a well characterised commercial antioxidative polyphenolic extract from the berries of Aronia melanocarpa (Aronox(®)). The comparative studies indicated that the analysed plant extracts were comparable to or even more effective in reducing the oxidation processes than the A. melanocarpa extract. The present study suggests that natural extracts from S. altissima and S. alpina have antioxidant activities and, therefore, may be beneficial in the prevention of diseases related to oxidant stress, such as cancer, cardiovascular, and inflammatory diseases.

    Dietary stilbenoids are receiving increasing attention due to their potential health benefits. However, most studies concerning the bioactivity of stilbenoids were conducted with pure compounds, for example, resveratrol. The aim of this study was to characterize a complex root extract of Vitis vinifera in terms of its free radical scavenging and cellular antioxidant and anti-inflammatory properties. HPLC-ESI-MS/MS analyses of the root extract of Vitis vinifera identified seven stilbenoids including two monomeric (resveratrol and piceatannol), two dimeric (trans-ɛ-viniferin and ampelopsin A), one trimeric (miyabenol C), and two tetrameric (r-2-viniferin = vitisin A and r-viniferin = vitisin B) compounds which may mediate its biological activity. Electron spin resonance and spin trapping experiments indicate that the root extract scavenged 2,2-diphenyl-1-picrylhydrazyl, hydroxyl, galvinoxyl, and superoxide free radicals. On a cellular level it was observed that the root extract of Vitis vinifera protects against hydrogen peroxide-induced DNA damage and induces Nrf2 and its target genes heme oxygenase-1 and γ-glutamylcysteine synthetase. Furthermore, the root extract could induce the antiatherogenic hepatic enzyme paraoxonase 1 and downregulate proinflammatory gene expression (interleukin 1β, inducible nitric oxide synthase) in macrophages. Collectively our data suggest that the root extract of Vitis vinifera exhibits free radical scavenging as well as cellular antioxidant and anti-inflammatory properties.

    Full Text Available The present study was designed to investigate the in vitro and in vivo free radical scavenging effect of aqueous extract of Desmodium gangeticum (DG root in different antioxidant models and experimentally induced ischemic reperfusion in an isolated rat heart. The rats were divided into three groups namely control, reperfusion control, and drug treated. For in vivo study, ischemic reperfusion injury (IRI was induced by 30 minutes ischemia followed by reperfusion of Krebs-Henseleit buffer for 15 minutes or 30 minutes or 45 minutes. Oral administration of DG extract (50 and 100 mg/kg once daily for 30 days was performed in rats of drug group and an increase of enzymatic activity of SOD, catalase and GPx along with an inhibition of lipid per-oxidations were observed. However, a significant rise in lipid peroxidation and reduction in myocardial SOD, catalase, and GPx were observed during IRI. The inhibitory concentrations (IC 50 in DPPH, superoxide scavenging activity, hydroxide scavenging activity, nitric oxide scavenging activity and lipid peroxidation were found to be 51.3, 24.6, 52.7, 53.2 and 415 µg/mL respectively. The presence of cactine, an alkaloid used to treat irregular heartbeat, angina pectoris and cardiac neuralgia was reported in DG through GS-MS analysis. The above results suggest that the aqueous extract of DG root exhibit potential free radical scavenging effect that can reduce the oxidative stress exhibited by IRI.

    Objective: The purpose of the present investigation is to rule out the antacid activity of Tephrosiapurpurea root by in vitro method using a self fabricated and modified artificial stomach model. The reason for selecting in vitro method was to minimize the usage of experimental animals. Method:In this work we have used air bubbles from an aerator to mimic the peristaltic movements of stomach. Sodium bicarbonate and water were used as reference and control respectively. The parameters evaluated were neutralizing effect, duration of neutralization effect and capacity and effect of temperature on pH. We evaluated the potency of the plant by extracting with three solvents in increasing order of polarity. Results: The neutralization effect, duration of neutralization effect and capacity were found to be higher for methanol root extract than sodium bicarbonate, whereas ethyl acetate and chloroform extract produced moderately good response but less when compared to standard drug but higher than water. Conclusion: Hence this plant can be an effective alternative for sodium bicarbonate which is reported to have side effects like edema n the feet, alteration in systemic pH, belching etc.

    Four protocols viz., the trichloroacetic acid-acetone (TCA), phenol-ammonium acetate (PAA), phenol/SDS-ammonium acetate (PSA) and trisbase-acetone (TBA) were evaluated with modifications for protein extraction from banana (Grand Naine) roots, considered as recalcitrant tissues for proteomic analysis. The two-dimensional electrophoresis (2-DE) separated proteins were compared based on protein yield, number of resolved proteins, sum of spot quantity, average spot intensity and proteins resolved in 4-7 pI range. The PAA protocol yielded more proteins (0.89 mg/g of tissues) and protein spots (584) in 2-DE gel than TCA and other protocols. Also, the PAA protocol was superior in terms of sum of total spot quantity and average spot intensity than TCA and other protocols, suggesting phenol as extractant and ammonium acetate as precipitant of proteins were the most suitable for banana rooteomics analysis by 2-DE. In addition, 1:3 ratios of root tissue to extraction buffer and overnight protein precipitation were most efficient to obtain maximum protein yield.

    The cancer-preventive activity of an extract of Withania somnifera (WS) roots was examined in female transgenic (MMTV/Neu) mice that received a diet containing the extract (750 mg/kg of diet) for 10 months. Mice in the treated group (n=35) had an average of 1.66 mammary carcinomas, and mice in the control group (n=33) had 2.48, showing a reduction of 33%. The average weights of the carcinomas were 2.36 g for mice in the treated group and 2.63 g for the controls, a difference of 10%. Labeling indices for Ki67 and proliferating cell nuclear antigen marker in mammary carcinomas of the treated group were 35% and 30% lower, respectively, than those of the corresponding control group. Expression of the chemokine was reduced by 50%. These results indicate that the root extract reduced the number of mammary carcinomas that developed and reduced the rate of cell division in the carcinomas.

    Carpolobia lutea, commonly called cattle stick or poor man's candle, is used by traditional herbalists in eastern Nigeria to treat 'madness'. It has a reported analgesic and anti-nociceptive effect. The effect of its ethanolic root extract on learning and memory was investigated. Thirty mice were divided into three groups of ten each. One group of mice served as the control and was given normal saline (p.o.) while the other two groups were given acute low dose (1500mg/kg, p.o.) and high dose (2500mg/kg, p.o.) (LD50 3338.83mg/kg). The effect of the extract on cognitive memory was investigated using the Novel Object recognition task (NORT) while the effect on visuospatial learning and memory was studied using the Morris Water maze (MWM). The results obtained in the NORT show that the index of habituation was significantly lower following acute treatment with a low dose of C. lutea extract compared to control. However, the index of habituation did not differ following treatment with a high dose of C. lutea compared to control but it was higher compared to the low dose. Following treatment with a low dose of the extract, the index of discrimination was significantly higher compared to control. The index of discrimination in the high dose treatment group did not differ from control, but it was lower compared to the low dose treatment. This indicated that there was improved cognitive memory only in the low dose treatment group. In the MWM there was no significant difference in swim latency during Acquisition and Reversal training. There also was no significant difference in quadrant duration during probe trial. The swim latency during the visible platform test showed that all mice used had good visual acuity. Therefore, the ethanolic extract of C. lutea root enhanced cognitive memory. However it did not affect visuospatial learning and memory.

    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.

    Phenolic compounds have different biological properties, including antioxidative activities, but they may also be prooxidants. The effect of phenolic fraction from roots of Alhagi maurorum on oxidative protein/lipid damages (determined by such parameters as levels of protein thiol groups and the concentration of thiobarbituric acid reactive species--TBARS) in human blood platelets and human plasma after treatment with hydrogen peroxide--H2O2 (which is the strong biologic oxidant and inflammatory mediator) was studied in vitro. We also studied the effect of A. maurorum extract on blood platelet activation corresponding to thrombin-induced arachidonic acid pathway. Moreover, the present work was designed to study the effect of A. maurorum extract on selected physiological function of blood platelets--adhesion of blood platelets to collagen in vitro. The action of phenolic fraction from A. maurorum was compared with the selected commercial phenolic extracts: extract from berries of Aronia melanocarpa (Aronox®), extract from bark of Yucca schidigera and monomeric polyphenol-resveratrol (3,4',5-trihydroxystilbene). Exposure of blood platelets or plasma to H2O2 resulted in a decrease of the level of thiol groups in proteins, and an increase of TBARS. In the presence of phenolic fraction from A. maurorum (0.5-50 µg/ml), a reduction of thiol groups oxidation together with the decrease of autoperoxidation of lipids and lipid peroxidation caused by H2O2 or thrombin was observed. The inhibitory, concentration-dependent effects of A. maurorum extract on adhesion of thrombin-activated platelets to collagen were also found. The phenolic fraction from A. maurorum acts as an antioxidant and can be useful as the natural factor protecting against diseases associated with oxidative stress. Tested fraction from A. maurorum has more effective antioxidative activity and antiplatelet properties than aronia extract or other commercial extract, however differences between their actions

    2,4-Dichlorophenol (2,4-DCP) is widely distributed in wastewaters discharged from several industries, and it is considered as a priority pollutant due to its high toxicity. In this study, the use of different peroxidase extracts for 2,4-DCP removal from aqueous solutions was investigated. Tobacco hairy roots (HRs), wild-type (WT), and double-transgenic (DT) for tomato basic peroxidases (TPX1 and TPX2) were used to obtain different peroxidase extracts: total peroxidases (TPx), soluble peroxidases (SPx), and peroxidases ionically bound to the cell wall (IBPx). All extracts derived from DT HRs exhibited higher peroxidase activity than those obtained from WT HRs. TPx and IBPx DT extracts showed the highest catalytic efficiency values. The optimal conditions for 2,4-DCP oxidation were pH 6.5, H2O2 0.5 mM, and 200 U mL(-1) of enzyme, for all extracts analyzed. Although both TPx extracts were able to oxidize different 2,4-DCP concentrations, the removal efficiency was higher for TPx DT. Polyethylene glycol addition slightly improved 2,4-DCP removal efficiency, and it showed some protective effect on TPx WT after 2,4-DCP oxidation. In addition, using Lactuca sativa test, a reduction of the toxicity of post removal solutions was observed, for both TPx extracts. The results demonstrate that TPx extracts from both tobacco HRs appear to be promising candidate for future applications in removing 2,4-DCP from wastewaters. This is particularly true considering that these peroxidase sources are associated with low costs and are readily available. However, TPx DT has increased peroxidase activity, catalytic efficiency, and higher removal efficiency than TPx WT, probably due to the expression of TPX1 and TPX2 isoenzymes.

    Full Text Available Proteases have been widely used in cancer treatment, wounds healing, overcoming digestion disorder and other modern pharmaceutical applications. Proteases may be present in fruits and leaves of noni (Morinda citrifolia L. since the plant has been used traditionally in wound healing. This research aimed to purify proteases from noni’s fruits and leaves at two maturity stages, i.e. fruits with green-yellow (TK2 and white-yellow (TK4 skin colour, also leaves from shoot and base. Proteases were purified through several steps consisting of extraction, precipitation using saturated ammonium sulfate and dialysis followed by electrophoresis under denaturing conditions (SDS-PAGE and zymography. The specific activity of the four extracts showed different trend during purification. The specific activity of TK2 fruit, shoot and base leaves decreased whereas TK4 fruits increased. TK2 crude extract had a higher specific activity (3.79 U/mg than the other crude extracts. SDS-PAGE and zymogram using 12% acrylamide indicated that the dialysates were not pure proteases. The molecular weight profiles of the TK2 dialysates were similar to TK4 dialysates, while those of shoot leaves dialysates were similar to the base leaves dialysates. The SDS-PAGE separated the enzymes in the fruit dialysates into several bands of polypeptides,i.e. 24-26kDa, 14-15kDa, 12-13kDa and the smaller ones, and also separated the enzymes in the dialysates of leaves into two bands, 70kDa and 58-61.5kDa. Protease bands detected in the zymogram of fruits were estimated at ~25kDa, ~27kDa, and 37-38kDa, whereas of those of leaves were estimated at ~29kDa and ~50kDa. The ~25kDa and ~29kDa protein bands appearing in zymogram were similar to papain’s and bromelain’s molecular weight.

    Full Text Available BACKGROUND: Chronic Myelomonocytic Leukemia (CMML is a heterogeneous disease that is not only hard to diagnose and classify, but is also highly resistant to treatment. Available forms of therapy for this disease have not shown significant effects and patients rapidly develop resistance early on in therapy. These factors lead to the very poor prognosis observed with CMML patients, with median survival duration between 12 and 24 months after diagnosis. This study is therefore centered around evaluating the selective efficacy of a natural extract from dandelion roots, in inducing programmed cell death in aggressive and resistant CMML cell lines. METHODOLOGY/PRINCIPAL FINDINGS: To confirm the induction of programmed cell death in three human CMML cell lines, nuclear condensation and externalization of the phosphatidylserine, two main characteristics of apoptosis, were detected using Hoechst staining and annexin-V binding assay. The induction of another mode of cell death, autophagy, was determined using a monodansylcadaverine (MDC stain, to detect the formation of autophagy vacuoles. The results from this study indicate that Dandelion Root Extract (DRE is able to efficiently and selectively induce apoptosis and autophagy in these cell lines in a dose and time dependent manner, with no significant toxicity on non-cancerous peripheral blood mononuclear cells. More importantly, we observed early activation of initiator caspase-8, which led to mitochondrial destabilization and the induction of autophagy, suggesting that DRE acts through the extrinsic pathway of apoptosis. The inability of DRE to induce apoptosis in dominant-negative FADD cells, confirms the mechanism of action of DRE in in vitro models of CMML. CONCLUSION: The results from this study indicate that natural products, in particular Dandelion Root Extract, have great potential, as non-toxic and effective alternatives to conventional modes of chemotherapy available today.

    A local herb, Kacip Fatimah, is famous amongst Malay women for its uses in parturition; however, its phytochemical contents have not been fully documented. Therefore, a study was performed to evaluate the phenolics, flavonoids, and total saponin contents, and antibacterial and antifungal properties of the leaf, stem and root of three varieties of Labisia pumila Benth. Total saponins were found to be higher in the leaves of all three varieties, compared to the roots and stems. Leaves of var. pumila exhibited significantly higher total saponin content than var. alata and lanceolata, with values of 56.4, 43.6 and 42.3 mg diosgenin equivalent/g dry weight, respectively. HPLC analyses of phenolics and flavonoids in all three varieties revealed the presence of gallic acid, caffeic acid, rutin, and myricetin in all plant parts. Higher levels of flavonoids (rutin, quercitin, kaempferol) were observed in var. pumila compared with alata and lanceolata, whereas higher accumulation of phenolics (gallic acid, pyrogallol) was recorded in var. alata, followed by pumila and lanceolata. Antibacterial activities of leaf, stem and root extracts of all varieties determined against both Gram positive (Micrococcus luteus, Bacillus subtilis B145, Bacillus cereus B43, Staphylococcus aureus S1431) and Gram negative (Enterobacter aerogenes, Klebsiella pneumonia K36, Escherichia coli E256, Pseudomonas aeruginosa PI96) pathogens showed that crude methanolic extracts are active against these bacteria at low concentrations, albeit with lower antibacterial activity compared to kanamycin used as the control. Antifungal activity of methanolic extracts of all plant parts against Fusarium sp., Candida sp. and Mucor using the agar diffusion disc exhibited moderate to appreciable antifungal activities compared to streptomycin used as positive control.

    Dandelion extracts have been studied extensively in recent years for its anti-depressant and anti-inflammatory activity. Recent work from our lab, with in-vitro systems, shows the anti-cancer potential of an aqueous dandelion root extract (DRE) in several cancer cell models, with no toxicity to non-cancer cells. In this study, we examined the cancer cell-killing effectiveness of an aqueous DRE in colon cancer cell models. Aqueous DRE induced programmed cell death (PCD) selectively in > 95% of colon cancer cells, irrespective of their p53 status, by 48 hours of treatment. The anti-cancer efficacy of this extract was confirmed in in-vivo studies, as the oral administration of DRE retarded the growth of human colon xenograft models by more than 90%. We found the activation of multiple death pathways in cancer cells by DRE treatment, as revealed by gene expression analyses showing the expression of genes implicated in programmed cell death. Phytochemical analyses of the extract showed complex multi-component composition of the DRE, including some known bioactive phytochemicals such as α-amyrin, β-amyrin, lupeol and taraxasterol. This suggested that this natural extract could engage and effectively target multiple vulnerabilities of cancer cells. Therefore, DRE could be a non-toxic and effective anti-cancer alternative, instrumental for reducing the occurrence of cancer cells drug-resistance.

    Bacterial biofilms are serious concern in patients infected with urinary tract infections, complicated urinary tract infections and other device-associated infections. Microbes within the biofilms are effectively shielded from antibiotics and host immune cells, hence can be treated only with agents which has the potential to disassemble the biofilms. The study is focused on the root extracts of Arctium lappa Linn. as a source for complementary medicine against three major biofilm forming clinical isolates of Escherichia coli, Proteus mirabilis, and Serratia marcescens. Methanol extracts of burdock roots (BR) showed no bactericidal activity (p > 0.05) against the uropathogens, whereas restrained the biofilms (p < 0.05) on polystyrene and glass surfaces at a biofilm inhibitory concentration of 100 µg/mL. The 3D confocal laser scanning microscopy was used to analyze the biofilm architecture which showed significant reduction in the surface area. Z-stack analysis has also revealed substantial reduction in the biofilm thickness (E. coli-50.79%, P. mirabilis-69.49%, and S. marcescens-75.84%). Further, BR extracts also inhibited quorum-sensing (QS)-controlled cellular phenotypes such as violacein, prodigiosin, swarming motility, and cell surface hydrophobicity. LC-MS/MS analysis of BR extracts identified the presence of two major quercetin derivatives (miquelianin and peltatoside) along with few other constituent components. Exploring such phytocompounds will provide potential agents to treat infections caused by biofilm forming uropathogens. The antibiofilm and anti-QS agents will ultimately serve as armor, facilitating the host immune system to fight infections.

    Full Text Available The effect of oral administration of ethanolic root extract of Jatropha gossypifolia and prednisolone on the kidney histology and renal function of albino rats was studied to assess the safety and toxicity of the plant as an herbal remedy.The rats were divided into four groups I, II, III and IV. Group I served as control and was given feed and water only. Group II, III, and IV were subdivided into Group IIa, IIb, IIIa, IIIb, IVa and IVb. Groups IIa, IIIa, and IVa received 10 mg, 20 mg and 30 mg/kg b.w of the extract while Group IIb, IIIb and IVb received 10 mg ,20 mg and 30 mg/kg b.w of the extract respectively plus 10 mg/kg b.w of prednisolone per day. The animals were sacrificed on day 7, 10 and 14 and their kidneys harvested and processed for histological studies. Their blood was also collected for serum urea measurement.Photomicrographs of the histological sections of Groups II, III and IV rats revealed changes compared to the control group and serum urea levels were significantly higher in these groups. Histological changes observed are consistent with glomerulonephritis and include increased urinary (Bowman's space, shrinkage and distortion of the glomerular tuft as well as scarring of the glomeruli. Changes appear to be both dosage and time dependent and the administration of prednisolone as an adjunct did not exert any ameliorative effect.We conclude that ethanolic root extract of Jatropha gossypifolia is toxic to the kidney and causes increased urea retention in the blood.

The root dentin moisture of 66 extracted human mandibular single-rooted teeth was measured at baseline (day 0) and at 1, 3, 7, and 14 days using a digital grain moisture meter. The baseline dentin moisture value was used as a covariate in the generalized estimating equation (GEE) analysis. The mean dentin moisture values (%) ± standard deviation on days 0, 1, 3, 7, and 14 were 10.6±0.64, 14.3±0.71, 14.6±0.84, 14.4±0.64, and 14.7±0.75 (Group A); 11.4±0.94, 14.6±0.95, 14.6±0.76, 14.6±0.93, and 14.8±0.81 (Group B); and 10.2±0.95, 12.8±0.90, 13.3±0.95, 13.0±0.91, and 13.2±0.89 (Group C), respectively. The dentin moisture increased in all three groups; however, there was no overall significant difference in moisture between the formalin and sodium azide groups. PMID:19540443

    A new numerical method for solving the 1D Richard's equation has been proposed by P. Ross (Agronomy J., 2003, in press). The Kirchhoff transform or degree of saturation is used instead of the classical matrix potential. The solution can be used both for saturated or non saturated soils. Hydraulic properties are described using the Brooks and Corey model. The soil is discretized into layers. Their thickness can be larger than in classical matrix potential methods, due to the use of a time and space varying weighing procedure for the calculation of fluxes between layers. This allows the use of a non iterative procedure, ensuring a very fast numerical solution. Extensive tests showed that the new method was very accurate for bare soils. The next step was the addition of a root extraction module in order to account for plant transpiration. Two root water uptake modules with compensation mechanisms in case of water stress were chosen from the literature. They express the transpiration source term in the Richards equation as a linear function of a potential transpiration and take into account water stress and its effects on plant transpiration. These modules were proposed first by Lai and Katul (Adv. Water Resour., 2000) and Li et al. (J. Hydrol., 2001). The new version of the model has been tested in a systematic way with several soils characteristics, climate forcings, and evapotranspiration calculation. Like the tests without vegetation, the SiSPAT (Simple Soil Plant Atmosphere Transfer) model was considered as a reference after implementation of the same roots modules. The numerical solution was also tested using a soybean data set. The variations and the cumulative values like drainage, water content, real transpiration and real evapotranspiration were in a good agreement with the SiSPAT modelling, with a relative error of less than 3%. The error on soil evaporation remained important (about 20%) on low cumulative values (less than 20mm), i.e. when LAI was close to

    Objective: Bryonia aspera (Stev. ex Ledeb) is a plant that grows in northeast of Iran. In the present study, cytotoxic and apoptogenic properties of B. aspera root extract was determined against HN-5(head and neck squamous cell carcinoma) and Hela (cervix adenocarcinoma) cell lines. Materials and Methods: HN-5 and Hela cell lines were cultured in DMEM medium and incubated with different concentrations of B. aspera root extract. Cell viability was quantitated by MTT assay and the optical absorbance was measured at 570 nm (620 nm as the reference) by an ELISA reader, in each experiment. Apoptotic cells were assessed using PI staining of DNA fragmentation by flow cytometry (sub-G1 peak). The B. aspera inhibited 50% growth (IC50) of Hela and HN-5 cell lines at 100±28 μg/ml and 12.5±4 μg/ml, respectively after 48 hr of incubation. Results: Cell viability assay showed that inhibitory effects of B. aspera were time and dose-dependent in both cell lines, which were consistent with morphological changes, observed under light microscope. Apoptosis was investigated by flow cytometry in which percentage of apoptotic cells increased in a dose and time-dependent manner. Conclusion: Based on our data, B. aspera has cytotoxic effects in which apoptosis played an important role. Further evaluations are needed to assess the possible anti-tumor properties of this plant.

    Full Text Available Erythrina velutina Willd., Fabaceae, is a medicinal plant that can be found in the tropics and subtropics, including in the semi-arid northeastern Brazil. It is commonly used in folk medicine to treat anxiety, agitation and insomnia. E. velutina has been known to present analgesic, anti-inflammatory and antibacterial activities, however, it is unknown if this plant present a protective effect on DNA. We assessed the antigenotoxic effect of E. velutina against the genotoxic effects induced by MMS in the root meristem cells of Allium cepa. Three concentrations of the aqueous extract (100, 200 and 400 mg/L of this medicinal plant were used in three different types of treatment (pre-, post- and simultaneous. The effects of the extracts on the root meristem cells of A. cepa were analyzed at both macroscopic and microscopic levels. Protective effects were observed at higher concentrations in pre-treatment and in simultaneous treatment. The results suggest that E. velutina may present antigenotoxic properties and demonstrate its chemopreventive potential.

    Full Text Available This case report illustrates determination of prognosis and immediate resection carried out, before completing the endodontic therapy, during the surgery employed for managing a nonperiodontal problem. This case showed external pressure resorption in the distobuccal root of maxillary second molar caused by the impingement of impacted third molar. Extraction of third molar was decided when healing was not seen, despite initiating endodontic therapy in second molar. Following elevation of flap and extraction of third molar, the poor prognosis due to severe bone loss around the resorbed root was evident. But due to strategic value of second molar, it was found beneficial to employ resection. Therefore, immediate resection was carried out in the same surgical field before the completion of endodontic therapy. This prevented the need for another surgical entry with its associated trauma to carry out resection separately later. Resection followed by the completion of endodontic therapy and full crown assisted in salvaging the remaining functional portion of the tooth and prevented the occurrence of distal extension with its potential drawbacks.

    Full Text Available The metabolic syndrome (MS is a condition consisting of various metabolic abnormalities that are risk factors for developing kidney failure, cardiovascular, vascular and cerebrovascular diseases, among others. The prevalence of this syndrome shows a marked increase. The aim of this study was to investigate the pharmacological effect of Smilax aristolochiifolia root on some components of MS and obtain some of the active principle using chromatographic techniques. The compound isolated was N-trans-feruloyl tyramine NTF (1, and its structure was determined by spectroscopic and spectrometric analyses. The whole extract and the standardized fractions were able to control the weight gain around 30%; the fraction rich in NTF was able to decrease the hypertriglyceridemia by 60%. The insulin resistance decreased by approximately 40%; the same happened with blood pressure, since the values of systolic and diastolic pressure fell on average 31% and 37% respectively, to levels comparable to normal value. The treatment also had an immunomodulatory effect on the low-grade inflammation associated with obesity, since it significantly decreased the relative production of pro-inflammatory cytokines regarding anti-inflammatory cytokines, both kidney and adipose tissue. Therefore it can be concluded that the extract and fractions of Smilax aristolochiifolia root with NTF are useful to counteract some symptoms of MS in animal models.

    Leaf extract of Morinda citrifolia L. was assessed for the synthesis of silver nanoscale particles under different temperature and reaction time. Synthesized nanoscale (MCAgNPs) particles were confirmed by analysing the excitation of surface plasmon resonance (SPR) using UV-visible spectrophotometer at 420 nm. Further SEM, HRTEM analysis confirmed the range of particle size between 10 and 60 nm and SEAD pattern authorizes the face centered cubic (fcc) crystalline nature of the MCAgNPs. Fourier transform infrared spectrum (FTIR) of synthesized MCAgNPs confirms the presence of high amount of phenolic compounds in the plant extract which may possibly influence the reduction process and stabilization of nanoparticles. Further, inhibitory activity of MCAgNPs and plant extract were tested against human pathogens like Eschericia coli, Pseudomonas aeroginosa, Klebsiella pneumoniae, Enterobacter aerogenes, Bacillus cereus and Enterococci sp. The results indicated that the MCAgNPs showed moderate inhibitory actions against human pathogens than crude plant extract, demonstrating its antimicrobial value against pathogenic diseases.

    Withania somnifera is a widely used medicinal plant for several disorders. Toxicity studies on Withania somnifera are not available. Acute and sub-acute oral toxicities of Withania somnifera root extract in Wistar rats were evaluated in the present study. In the acute toxicity study, WSR extract was administered to five rats at 2000 mg/kg, once orally and were observed for 14 days. No toxic signs/mortality were observed. In the sub-acute study, WSR extract was administered once daily for 28 days to rats at 500, 1000 and 2000 mg/kg, orally. No toxic signs/mortality were observed. There were no significant changes (P < 0.05) in the body weights, organ weights and haemato-biochemical parameters in any of the dose levels. No treatment related gross/histopathological lesions were observed. The present investigation demonstrated that the no observed adverse effect level was 2000 mg/kg body weight per day of hydroalcoholic extract of W. somnifera in rats and hence may be considered as non-toxic.

    Full Text Available Slaking experiments were conducted of fragipan clods immersed in solutions of poultry manure, aerobically digested biosolid waste (ADB, fluidized bed combustion byproduct (FBC, D-H2O, CaCO3, NaF, Na-hexa-metaphosphate, and ryegrass root biomass. The fragipan clods were sampled from the Btx horizon of an Oxyaquic Fragiudalf in Kentucky. Wet sieving aggregate analysis showed significantly better fragmentation in the NaF, Na-hexa-metaphosphate, and ryegrass root solutions with a mean weight diameter range of 15.5–18.8 mm compared to the 44.2–47.9 mm of the poultry manure, ADB, and FBC treatments. Dissolved Si, Al, Fe, and Mn levels released in solution were ambiguous. The poor efficiency of the poultry manure, ADB, and FBC treatments was attributed to their high ionic strength, while the high efficiency of the NaF, Na-hexa-metaphosphate, and rye grass root solutions to their high sodium soluble ratio (SSR. A slaking mechanism is proposed suggesting that aqueous solutions with high SSR penetrate faster into the fragipan capillaries and generate the critical swelling pressure and shearing stress required to rupture the fragipan into several fragments. Additional fragmentation occurs in a followup stage during which potential Si, Al, Fe, and Mn binding agents may be released into solution. Field experiments testing these findings are in progress.

    Objective:To assess the effect of plumbagin-free alcohol extract (PFAE) ofPlumbago zeylanica Linn. (Plumbaginaceae) (P. zeylanica) root, on female reproductive system and fertility of adult female wistar rats.Methods: After the oral acute toxicity study, thePFAE was administered at two dose levels to perform the estrous cycle study, anti-implantation and abortifacient activity and hormonal analysis. However, the estrogenic/antiestrogenic activity was evaluated at only one most effective dose.Results:LD50cut-off was5 000 mg/kg body weight. The extract exhibited significant anti-implantation and abortifacient activity at the tested dose levels (300 and500 mg/kg,p.o.) (P<0.01). The extract dose-dependently decreased the levels of serum progesterone, follicle stimulating hormone and luteinizing hormone, while a dose-dependent increase was observed in the concentration of serum prolactin. The extract did not show any significant changes in structure and function of uterus when given alone, but when given along with ethinyl estradiol, it exhibited significant antiestrogenic activity in immature overiectomized female rats(P<0.001). Biochemical parameters in the serum/blood and haematological parameters did not show appreciable changes throughout and after the course of investigation. However, all the altered parameters returned to normalcy within30 days following withdrawal of treatment. Conclusions: All findings suggest that the antifertility activity of extract could possibly be through the changes in the implantation site, altered hormonal levels, prolonged estrous cycle and anti-estrogenic activity. Hence, the extract possesses reversible antifertility activity without adverse toxicity in female rats.

    Full Text Available On the basis of reports that ginger (Zingiber officinale, Z. officinale extract has antiinfalammatory activity, the present study was undertaken to investigate whether the aqueous extract of Z. officinale has any significant beneficial effect on chronic inflammation in diabetic mice. Control mice received normal saline (0.1 ml, i.p., and in the test group, diabetes was induced by injection of streptozotocin (STZ, 180mg/kg, i.p. which was confirmed by the measurement of blood glucose, 7 days after STZ injection. One week after saline or STZ injection, chronic inflammation was induced by implantation of cotton pellets (30 mg on each side of the groin region subcutaneously. Then at the day of 3, the aqueous extract of Z.officinale was added to drinking water (100, 200 and 400 mg/100 ml for 4 days. In another sets of experiments, L-NAME, a nitric oxide synthase inhibitor, (0.1 mg/kg, i.p. and indomethacin, an inhibitor of the prostaglandin biosynthesis, (2 mg/kg, i.p. were injected at the day of 5 of implantation. On the 8th day, the mice were killed and the pellets were removed, freed from extraneous tissue and dried at 60 °C for 24h. The increase in the weight of cotton pellets was higher in diabetic mice (control: 160 ± 13.6 mg,diabetic: 271 ± 11.8 mg, P<0.001. Pretreatment with the aqueous extract of Z. officinale caused a significant but not dose-dependent reduction in cotton pellet weight in diabetic animals (diabetic + Z.officinale's extract: 181.4 ± 21 mg, P<0.05 vs diabetic. The anti-inflammatory effect of extract was almost the same as L-NAME, but less than indomethacin. Results suggest that the anti-inflammatory effects of aqueous extract of Z. officinale are comparable to L-NAME.

    Full Text Available The active principles from the aqueous liquorice plant extracts were investigated and quantified by evaluation of bioactive compounds (saponins through phytochemical reactions. The presence of saponins was evaluated by measuring the foam index, which was around 500. A major component was Glycyrrhizic acid, responsible for the antioxidant activity, found in concentration of 5.82 % at plant maturity. A time-dependent decrease in concentration of the bioactive compounds from aqueous liquorice extracts was observed. The antimicrobial activity of the extracts was tested by the agar diffusion method, showing a moderate inhibitory activity against Bacillus sp. and strong inhibitory activity against coliforms. A liquorice syrup was obtained and subsequently could be used as nutraceutical additive in bread with good results, showing characteristic, optical and antimicrobial properties and good stability in time. Adding liquorice syrup in food products could be an alternative to improve nutraceutical potential.

    Dogs are intensely integrated in human social life and their shed hairs can play a major role in forensic investigations. The overall aim of this study was to validate a semi-automated extraction method for mitochondrial DNA analysis of telogenic dog hairs. Extracted DNA was amplified with a 95% success rate from 43 samples using two new experimental designs in which the mitochondrial control region was amplified as a single large (± 1260 bp) amplicon or as two individual amplicons (HV1 and HV2; ± 650 and 350 bp) with tailed-primers. The results prove that the extraction of dog hair mitochondrial DNA can easily be automated to provide sufficient DNA yield for the amplification of a forensically useful long mitochondrial DNA fragment or alternatively two short fragments with minimal loss of sequence in case of degraded samples.

    ABSTRACT Objective:To evaluate the hepatoprotective potential of ethanolic (50%) extract ofZiziphus oenoplia (L.) Mill (Z. oenoplia) root against isoniazid(INH) and rifampicin(RIF) induced liver damage in animal models.Methods: Five groups of six rats each were selected for the study. Ethanolic extract at a dose of 150 and300 mg/kg as well as silymarin (100 mg/kg) were administered orally once daily for21d in INH + RIF treated groups. The serum levels of glutamic oxaloacetic transaminase(SGOT), glutamate pyruvate transaminase (SGPT), alkaline phosphatase (SALP), and bilirubin were estimated along with activities of superoxide dismutase, catalase, glutathione S-transferase, glutathione peroxidase, and hepatic melondialdehyde formation. Histopathological analysis was carried out to assess injury to the liver.Result: The considerably elevated serum enzymatic activities of glutamic oxaloacetic transaminase, glutamate pyruvate transaminase, alkaline phosphatase and bilirubin due toINH + RIF treatment were restored towards normal in a dose dependent manner after the treatment with ethanolic extract of Z. oenopliaroots. Meanwhile, the decreased activities of superoxide dismutase, catalase, glutathione S-transferase and glutathione peroxidase were also restored towards normal dose dependently. In addition, ethanolic extract also significantly prevented the elevation of hepatic melondialdehyde formation in the liver ofINH + RIF intoxicated rats in a dose dependent manner. The biochemical observations were supplemented with histopathological examination of rat liver sections.Conclusions: The results of this study strongly indicate that ethanolic extract of Z. oenoplia has a potent hepatoprotective action againstINH + RIF induced hepatic damage in rats.

    A comparison was made of water-soluble root exudates and extracts of Sorghum vulgare Pers. grown under two levels of P nutrition. An increase in P nutrition significantly decreased the concentration of carbohydrates, carboxylic acids, and amino acids in exudates, and decreased the concentration of carboxylic acids in extracts. Higher P did not affect the relative proportions of specific carboxylic acids and had little effect on proportions of specific amino acids in both extracts and exudates. Phosphorus amendment resulted in an increase in the relative proportion of arabinose and a decrease in the proportion of fructose in exudates, but did not have a large effect on the proportion of individual sugars in extracts. The proportions of specific carbohydrates, carboxylic acids, and amino acids varied between exudates and extracts. Therefore, the quantity and composition of root extracts may not be a reliable predictor of the availability of substrate for symbiotic vesicular-arbuscular mycorrhizal fungi. Comparisons of the rate of leakage of compounds from roots with the growth rate of vesicular-arbuscular mycorrhizal fungi suggest that the fungus must either be capable of using a variety of organic substrates for growth, or be capable of inducing a much higher rate of movement of specific organic compounds across root cell membranes than occurs through passive exudation as measured in this study.

    Primary cultures of rodent sensory neurons are widely used to investigate the cellular and molecular mechanisms involved in pain, itch, nerve injury and regeneration. However, translation of these preclinical findings may be greatly improved by direct validation in human tissues. We have developed an approach to extract and culture human sensory neurons in collaboration with a local organ procurement organization (OPO). Here we describe the surgical procedure for extraction of human dorsal root ganglia (hDRG) and the necessary modifications to existing culture techniques to prepare viable adult human sensory neurons for functional studies. Dissociated sensory neurons can be maintained in culture for >10 d, and they are amenable to electrophysiological recording, calcium imaging and viral gene transfer. The entire process of extraction and culturing can be completed in <7 h, and it can be performed by trained graduate students. This approach can be applied at any institution with access to organ donors consenting to tissue donation for research, and is an invaluable resource for improving translational research.

    Full Text Available Background: Root canal treatment consists of preparation, sterilization, and obturation. During root canal preparation, debris is smeared over the dentinal surface forming a smear layer. Smear layer will reduce the attachment of root canal filling materials. Organic material in smear layer can be substrated for microorganism. Preparation of root canal should be followed by irrigation. NaOCl is common irrigation solution in endodontics. It has been very effective for their disinfecting and tissue-dissolving properties, but it is incapable of removing the smear layer. On the other hand, saponin of mangosteen peel extract has an ability as a surfactant to lower the surface tension, and it can dissolve debris containing of anorganic and organic materials. Purpose: This study aims to know the differences between 2.5% NaOCl and 0.002% saponin of mangosteen peel extract in removing the debris in the root canal after the preparation procedure. Method: Three groups of teeth (7 teeth in each were instrumented with K-file and irrigated as follow: group 1 (control with aquadest; group 2 with 2.5% NaOCl; and group 3 with 0.002% saponin of mangosteen peel extract. Furthermore, those teeth were split horizontally and longitudinally 4mm above the apical. The apical third of root canal walls was observed by a scanning electron microscope (SEM. Result: There were significant differences between each group (p<0.05. Median value of the group 3 was score 1 considered as the smallest value. It indicates that Group 3 with 0.002% saponin of mangosteen peel extract was the cleanest group. Conclusion:It can be concluded that 0.002% saponin of mangosteen peel extract can clean the smear layer of the root canal better than 2.5% NaOCl.

Evaluating solubility investigations, the extraction temperature was fixed at 85 degrees C. The inulin stability regarding degradation or hydrolysis could be confirmed by extraction in the presence of model inulin. Confirming stability at the given conditions the isolation procedure was transferred from a 1 L- to a 1 m3-reactor. The Reynolds number was selected as the relevant dimensionless number that has to remain constant in both scales. The stirrer speed in the large scale was adjusted to 3.25 rpm regarding a 300 rpm stirrer speed in the 1 L-scale and relevant physical and process engineering parameters. Assumptions were confirmed by approximately homologous extraction kinetics in both scales. Since T. kok-saghyz is in the focus of research due to its rubber content side-product isolation from residual biomass it is of great economic interest. Inulin is one of these additional side-products that can be isolated in high quantity (- 35% of dry mass) and with a high average degree of polymerization (15.5) in large scale with a purity of 77%.

    Full Text Available ABSTRACT Information about the morphology, chemical composition and reserve mobilization is important in understanding the establishment of native and exotic species. The purpose of this study was to describe the morphology, chemical composition, and mobilization of reserves during germination of noni (Morinda citrifolia L.. Biometric and morphological analyzes were performed with 100 randomly selected dried seeds. Other seeds were treated with sulfuric acid PA and soaked in Petri dishes. Collected seeds of five different times of germination were used for cytochemical and chemical analysis. For cytochemical analysis, the cuts of 5μm were submitted to dyes TB at pH 4.0; XP at pH 2.5, reaction of PAS and Sudan IV. The seeds were crushed for chemical analysis with lipids, proteins and soluble sugars extraction that were determined gravimetrically, by the Bradford method and the Antrona method, respectively. The fatty acid composition of the dry seed was determined by gas chromatography. Noni seeds are albuminous and have a thick seed coat, rich in lignin. Lipid and protein bodies were observed inside the endosperm cells, representing 43.50% and 9.15% respectively, while the reservoir of soluble sugars was less than 5%. Linoleic acid was the most prevalent with 68.1%. The lipids were mobilized during germination, suffering a reduction of up to 38% of its total. Proteins, as well as lipids decreased by 25.78% during the germination period observed. The main reserves of noni seeds are lipids and proteins that are mobilized during germination to provide energy and matter to the developing embryo and synthesis of more complex compounds.

    Case selection and treatment plan are important aspects of endodontic treatment. Dentists should organize the treatment plan based on their knowledge, abilities, skills and more importantly the patients' preference and dentition. Indubitably, the treatment plan for each patient is exclusive and "tailor-made" and cannot be used for all patients. Dentists' selfestimation of their abilities opens up treatment options; however, in difficult or complicated cases it is advisable to refer to a specialist. Currently, one of the most challenging aspects in dentistry is the choice between extraction and placement of implant (EPI) instead of a complicated root canal treatment (RCT). Overemphasis on one treatment plan while neglecting other options, not only mislead the dentist but also impose unnecessary charges to the patients. This mini-review compares RCT to EPI from various aspects to help practitioners in routine decision making.

    Rhus tripartitum (sumac) is an Anacardiaceae tree with a wide phytotherapeutic application including the use of its roots in the management of gastric ulcer. In the present study the Rhus tripartitum root barks extract (RTE) was phytochemical studied, in vitro tested for their potential antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and reducing power assay and in vivo evaluated for its ability to prevent ethanol-induced gastric ulcer in rats. The RTE was rich in phenolics, flavonoids, tannins and polysaccharide contents and exhibited a low but not weak in vitro antioxidant activity when compared with (+)-catechin. Pre-treatment with RTE at oral doses 50, 200 and 400 mg/kg body weight was found to provide a dose-dependent protection against ethanol-induced ulcer by averting the deep ulcer lesions of the gastric epithelium, by reducing gastric juice and acid output, by enhancing gastric mucus production by preserving normal antioxidant enzymes activities, and inhibiting the lipid peroxidation. The antiulcerogenic activity of RTE might be due to a possible synergistic antioxidant and antisecretory effects.

    Cutaneous leishmaniasis (CL) manifests as localized skin lesions, which lead to significant tissue destruction and disfigurement. In the Yucatan Peninsula, Mayan traditional healers use Pentalinon andrieuxii Muell.-Arg. (Apocynaceae) roots for the topical treatment of CL. Here, we studied the effect of P. andrieuxii root hexane extract (PARE) on the parasites and host cells in vitro and examined its efficacy in the topical treatment of CL caused by L. mexicana. PARE exhibited potent antiparasitic activity in vitro against promastigotes as well as amastigotes residing in macrophages. Electron microscopy of PARE-treated parasites revealed direct membrane damage. PARE also activated NF-κB and enhanced IFN-γR and MHC class II expression and TNF-α production in macrophages. In addition, PARE induced production of the Th1 promoting cytokine IL-12 in dendritic cells as well as enhanced expression of the co-stimulatory molecules CD40, CD80 and CD86. In vivo studies showed that L. mexicana-infected mice treated by topical application of PARE resulted in the significant reduction in lesion size and parasite burden compared to controls. These findings indicate that PARE could be used as an alternative therapy for the topical treatment of CL. PMID:24347110

    Objective: The present study was carried out to investigate the hypoglycemic effects of the petroleum ether extract of Sesbania sesban (SS)(Merr.) roots, which are widely used in inflammation, fever, ulcers, leucoderma and diabetes in various parts of India. Methods: SS was administered orally at different doses (250, 500 and 1000mg/kg) to normal and streptozotocin (STZ) induced type- 2 diabetic mice. The fasting blood glucose (FBG), biochemical parameters in serum, change in body weight, internal organs weight, food intake, water intake and glycogen level in livers were performed for the evaluation of hypoglycemic effects.Results: All the doses of SS caused a marked decrease of FBG in STZ induced type -2 diabetic mice. SS decreased the cholesterol, triglyceride (TG), urea, creatinine level and increased the insulin, HDL cholesterol, and total protein level. Decrease in body weight and glycogen level induced by STZ was restored. Increase in water and food intake induced by STZ was decreased. Conclusions: The results suggest that SS may have hypoglycemic potential for the type 2- diabetes and support the traditional use of the roots of plant as a hypoglycemic agent.

    Full Text Available Ashwagandha (Withania somnifera has been described in traditional Indian Ayurvedic medicine as an aphrodisiac that can be used to treat male sexual dysfunction and infertility. This pilot study was conducted to evaluate the spermatogenic activity of Ashwagandha root extract in oligospermic patients. Forty-six male patients with oligospermia (sperm count < 20 million/mL semen were enrolled and randomized either to treatment (n=21 with a full-spectrum root extract of Ashwagandha (675 mg/d in three doses for 90 days or to placebo (n=25 in the same protocol. Semen parameters and serum hormone levels were estimated at the end of 90-day treatment. There was a 167% increase in sperm count (9.59 ± 4.37 × 106/mL to 25.61 ± 8.6 × 106/mL; P<0.0001, 53% increase in semen volume (1.74 ± 0.58 mL to 2.76 ± 0.60 mL; P<0.0001, and 57% increase in sperm motility (18.62 ± 6.11% to 29.19 ± 6.31%; P<0.0001 on day 90 from baseline. The improvement in these parameters was minimal in the placebo-treated group. Furthermore, a significantly greater improvement and regulation were observed in serum hormone levels with the Ashwagandha treatment as compared to the placebo. The present study adds to the evidence on the therapeutic value of Ashwagandha (Withania somnifera, as attributed in Ayurveda for the treatment of oligospermia leading to infertility.

    This paper addresses the problem of semi-automatic extraction of line networks in digital images - e.g., road or hydrographic networks in satellite images, blood vessels in medical images, robust. For that purpose, we improve a generic method derived from morphological and hydrological concepts and consisting in minimum cost path estimation and flow simulation. While this approach fully exploits the local contrast and shape of the network, as well as its arborescent nature, we further incorporate local directional information about the structures in the image. Namely, an appropriate anisotropic metric is designed by using both the characteristic features of the target network and the eigen-decomposition of the gradient structure tensor of the image. Following, the geodesic propagation from a given seed with this metric is combined with hydrological operators for overland flow simulation to extract the line network. The algorithm is demonstrated for the extraction of blood vessels in a retina image and of a river network in a satellite image.

    Full Text Available Seed germination under field conditions is highly influenced by the presence of other plants. Allelopathy is an important mechanism of plant competition, by producing phytotoxins to the plant environment in order to decline other plants growth. Soil sickness problem in farm lands is also known as an allelopathic effect or even autotoxicity. The toxicity of released allelochemicals by a plant in the environment is attributed to its function of concentration, age and metabolic stage. In this study we investigate the effect (5, 20, 35 and 50 g l-1 of leaf, stem and root water extract of sorghum on seed germination and seedling growth of mung bean. The results of the experiment showed that allelopathic effect of different concentrations was not significant for germination percentage, but germination rate and mean germination time decreased significantly by increasing the concentration of allelopathic extracts; also, there was a clear allelopathic effect of sorghum extract on seedling growth of mung bean. 50 g l-1 sorghum stem extract exhibited the highest inhibitory effect on root and shoot growth of mung bean. Among all parts of sorghum, stem extracts showed the highest allelopatic effect on seedling growth. Root extract showed higher inhibitory effect than leaf extracts.

    Raphanus sativus, a common cruciferous vegetable has been attributed to possess a number of pharmacological and therapeutic properties. It has been used in indigenous system of medicine for the treatment of various human ailments in India. This present study evaluated the chemopreventive efficacy of different parts of R. sativus such as root, stem and leaves, extracted with solvents of varying polarity and investigated the molecular mechanism leading to growth arrest and apoptotic cell death in human cancer cell lines. Of the different parts, significant growth inhibitory effect was observed with hexane extract of R. sativus root. Analysis of hexane extract by GC-MS revealed the presence of several isothiocyanates (ITCs) such as 4-(methylthio)-3-butenyl isothiocyanate (MTBITC), 4-(methylthio)-3-butyl isothiocyanate (erucin), 4-methylpentyl isothiocyanate, 4-pentenyl isothiocyanate and sulforaphene. R. sativus root extract induced cell death both in p53 proficient and p53 deficient cell lines through induction of apoptotic signaling pathway regardless of the p53 status of cells. The molecular mechanisms underlying R. sativus-induced apoptosis may involve interactions among Bcl(2) family genes, as evidenced by up-regulation of pro-apoptotic genes and down-regulation of anti-apoptotic genes along with activation of Caspase-3. Our findings present the first evidence that hexane extract of R. sativus root exerts potential chemopreventive efficacy and induces apoptosis in cancer cell lines through modulation of genes involved in apoptotic signaling pathway.

    Morinda citrifolia, also known as Great Morinda, Indian Mulberry, or Noni, is a plant belonging to the family Rubiaceae. A number of major chemical compounds have been identified in the leaves, roots, and fruits of Noni plant. The fruit juice is in high demand in alternative medicine for different kinds for illnesses such as arthritis, diabetes, high blood pressure, muscle ached and pains, menstrual difficulties, headache, heart diseases, AIDS, gastric ulcer, sprains, mental depression, senility, poor digestion, arteriosclerosis, blood vessel problems, and drug addiction. Several studies have also demonstrated the anti-inflammatory, antioxidant and apoptosis-inducing effect of Noni in various cancers. Based on a toxicological assessment, Noni juice was considered as safe. Though a large number of in vitro, and, to a certain extent, in vivo studies demonstrated a range of potentially beneficial effects, clinical data are essentially lacking. To what extent the findings from experimental pharmacological studies are of potential clinical relevance is not clear at present and this question needs to be explored in detail before an recommendations can be made.

    In the present study, the effect of DG chloroform root extract was assessed on isolated rat heart and in-vitro antioxidant models. Ischemia reperfusion injury was experimentally induced by using Langendroff apparatus. The free radical scavenging potential was studied in vitro by using different antioxidant models such as DPPH, super oxide scavenging activity, hydroxide scavenging activity and nitric oxide scavenging activity. Both experimental approaches not only substantiate its antioxidant potential but also the cardio-protection imparted by the extract. The cardio-stimulatory effects were investigated for the extract by treating it as a pre-conditioning agent against myocardial ischemia reperfusion injury. The improved antioxidant status of the myocardium indirectly predicts reduced oxidative stress mediated by ischemic reperfusion with evident reduction of infarct size determined by cardiac marker protein. These findings indicate that DG chloroform root extract may possess therapeutic potential against ischemia reperfusion injury.

    Asparagus cochinchinensis is a traditional Chinese medicine used for treating lung and spleen-related diseases. In this study, we compared the medicinal effects of A. cochinchinensis root and stem extracts on the activity of superoxide dismutase (SOD), the content of malonaldehyde (MDA) and total protein content in the brain, liver and plasma of mice. Polysaccharides and aqueous extracts of the roots significantly increased the spleen index and the SOD activity but reduced the MDA content and slowed down the aging process. In contrast, feeding with the stem extracts significantly reduced the SOD activity and increased the MDA accumulation in the brain and liver of mice, suggesting that the stem extracts may not be appropriate for treating aging-related diseases.

    Root exudates can play an important role in plant-nematode interactions. Recent studies have shown that the root cap exudates obtained from several plant species trigger a state of dormancy or quiescence in various genera of nematodes. This phenomenon is not only of fundamental ecological interest, but also has application potential if the plant-produced compound(s) could be used to control harmful nematodes or help to prolong the shelf-life of beneficial entomopathogenic nematodes (EPNs). The identification of the compound(s) involved in quiescence induction has proven to be a major challenge and requires large amounts of active material. Here, we present a high-throughput method to obtain bioactive root extracts from flash-frozen root caps of green pea and maize. The root cap extract obtained via this method was considerably more potent in inducing quiescence than exudate obtained by a previously used method, and consistently induced quiescence in the EPN Heterorhabditis megidis, even after a 30-fold dilution. Extracts obtained from the rest of the root were equally effective in inducing quiescence. Infective juveniles (IJs) of H. megidis exposed to these extracts readily recovered from their quiescent state as soon as they were placed in moist soil, and they were at least as infectious as the IJs that had been stored in water. Excessive exposure of IJs to air interfered with the triggering of quiescence. The implications of these results and the next steps towards identification of the quiescence-inducing compound(s) are discussed from the perspective of applying EPN against soil-dwelling insect pests.

    This study was performed to determine the effects of Arctium lappa (Al) to protect against cadmium damage in the rat liver. Male rats received a single i.p. dose of CdCl2 (1.2 mg/kg body weight (BW)) with or without Al extract administered daily by gavage (300 mg/kg BW) for 7 or 56 days. After 7 days, Al caused plasma transaminase activity to diminish in groups Al (glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT)) and CdAl (GPT). After 56 days, GOT and GPT plasma activities were reduced in the Cd group. No alteration in plasma levels of creatinine, total bilirubin, and total protein were observed. GOT liver activity increased in the Cd group. No alteration was observed in superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), and malondialdehyde (MDA) dosage. In the Cd group, hepatocyte proportion decreased and sinusoid capillary proportion increased. In the Al and CdAl groups, the nuclear proportion increased and the cytoplasmic proportion decreased. The hepatocyte nucleus density reduced in Cd and increased in the Al group. After 56 days, there was no alteration in the Cd group. In Al and CdAl groups, the nuclear proportion increased without cytoplasmic proportion variation, but the sinusoid capillary proportion was reduced. The hepatocyte nucleus density decreased in the Cd group and increased in the Al and CdAl groups. In conclusion, the liver function indicators showed that A. lappa protected the liver against cadmium toxicity damage.

    The neuroprotective effect of an ethyl acetate extract of Morinda citrifolia (Rubiaceae) Linn. fruits (EMC, ethyl acetate extract of Morinda citrifolia) at doses of 200 and 400 mg/kg, p.o. was studied on beta-amyloid (25-35) peptide induced cognitive dysfunction in mice. In the step-down inhibitory avoidance, EMC exhibited a significant increase in short-term memory and long-term memory (p < 0.05). A significant decrease (p < 0.01) in escape latency was noticed in the animals in the water maze. A significant increase (p < 0.01) in alteration of behavior was exhibited upon administration of EMC 200 and 400 mg/kg on the Y maze. Exploratory parameters such as line crossings, head dipping and rearing were increased significantly in EMC treated groups in a dose-dependent manner (p < 0.05 and p < 0.01). A significant reduction (p < 0.05) in acetyl cholinesterase activity was noticed in the EMC 200 and 400 mg/kg treated groups. The level of monoamine oxidase-A was decreased by the administration of EMC 200 and 400 mg/kg (p < 0.05 and p < 0.01, respectively). EMC at a dose of 400 mg/kg exhibited a significant increase (p < 0.01) in the levels of serotonin and dopamine. Antioxidant enzymes such as superoxide dismutase, glutathione reductase, glutathione peroxidase and ascorbic acid were decreased significantly in the b-amyloid peptide injected group, whose levels were restored significantly (p < 0.01) by the administration of EMC (400 mg/kg).

    Previous studies demonstrated that Withania somnifera Dunal (WS), a safe medicinal plant, prevents the development of tolerance to the analgesic effect of morphine. In the present study, we investigated whether WS extract (WSE) (100 mg/kg, i.p.) may also modulate the analgesic effect induced by acute morphine administration (2.5, 5, 10 mg/kg, s.c.) in the tail-flick and in the hot plate tests, and if it may prevent the development of 2.5 mg/kg morphine-induced rebound hyperalgesia in the low intensity tail-flick test. Further, to characterize the receptor(s) involved in these effects, we studied, by receptor-binding assay, the affinity of WSE for opioid (μ, δ, k), cannabinoid (CB1, CB2), glutamatergic (NMDA), GABAergic (GABAA, GABAB), serotoninergic (5HT2A) and adrenergic (α2) receptors. The results demonstrated that (i) WSE alone failed to alter basal nociceptive threshold in both tests, (ii) WSE pre-treatment significantly protracted the antinociceptive effect induced by 5 and 10 mg/kg of morphine only in tail-flick test, (iii) WSE pre-treatment prevented morphine-induced hyperalgesia in the low intensity tail-flick test, and (iv) WSE exhibited a high affinity for the GABAA and moderate affinity for GABAB, NMDA and δ opioid receptors. WSE prolongs morphine-induced analgesia and suppresses the development of morphine-induced rebound hyperalgesia probably through involvement of GABAA, GABAB, NMDA and δ opioid receptors. This study suggests the therapeutic potential of WSE as a valuable adjuvant agent in opioid-sparing therapies.

Methods:The studiedArtemisia species wereArtemisia absinthium, Artemisia khorasanica, Artemisia deserti, Artemisia fragrans, Artemisia aucheri, Artemisia sieberi andArtemisia vulgaris. The activity of these plant extracts onHIV-1 replication andCD4 expression was performed byHIV-1 p24 antigen kit and flow cytometry respectively. Results: The results demonstrated that flower extracts of all species increasedPBMCs number more than shoot, leaf and root extracts. However, the frequency ofCD4 expression inPBMC was not increased in the presence of all flower extracts. The flower extracts of all species had inhibitory effect onHIV-1 replication. Conclusions:In conclusion, the results demonstrated that flower extracts ofArtemisia species are good candidates for further studies as anticancer agents.

    The main objective of this study was to investigate the effects of cultured wild ginseng root extracts (cWGRE) on the sperm of boars and the reproductive system of guinea pigs. Firstly, semen collected from boars (n=10) were incubated in 38°C for 1h with xanthine and xanthine oxidase to generate ROS. The cWGRE was added to the sperm culture system to test its antioxidant effect on the boar sperm. The amount of Reactive Oxygen Species (ROS) was measured by a chemiluminescence assay using luminol. The results indicated that the addition of cWGRE to boar sperm culture inhibited xanthine and xanthine oxidase-induced ROS concentrations. Treatment with cWGRE also had a positive effect on maintaining sperm motility. Effects of cWGRE administration on vitamin C-deficient guinea pigs were further investigated. Hartley guinea pigs (n=25) at 8 weeks of age were randomly divided into five groups. With the exception of the positive control group, each group was fed vitamin C-deficient feed for 21days (d). Respective groups were also orally administered cWGRE, ginseng extract, or mixed ginsenosides for 21 days. In comparison to the control group, oral administration of cWGRE reduced (P<0.05) amount of lipid peroxidation and increased (P<0.05) both glutathione peroxidase concentrations and the trolox equivalent antioxidant capacity. In addition, administration of cWGRE induced increases (P<0.05) in body weight, testosterone concentrations, and spermatid populations. The results of the present study support our hypothesis that cWGRE has positive effects on male reproductive functions via suppression of ROS production.

    Objective: To determine the anti-breast cancer activities and the safety oral consumption of Dillenia suffruticosa root aqueous extract (DRAE) in BALB/c mice. Methods: In the anti-breast cancer study, female BALB/c mice were divided into five groups (n = 12), which were (1) positive control (with breast cancer, untreated), (2) negative control (without breast cancer, untreated) and other three groups of mice with breast cancer treated with 1 000, 500 and 250 mg/kg of DRAE, respectively, by oral gavage for 28 days. All mice except from the negative control group were injected into the mammary fat pad with 4T1 cells (1 × 105 4T1 cells/0.1 mL of phosphate buffer solution). DRAE was administered orally on Day 11 after the tumor has developed. Results: The tumor volume of the 1 000 mg/kg of DRAE group reduced significantly compared to the positive control while treatment with 500 mg/kg of DRAE had signif-icantly inhibited metastasis to the heart. In the acute toxicity study, treatment with up to 5 000 mg/kg of DRAE was not toxic to the animals, indicating its safety when a large amount of this plant extract was ingested. Based on the sub-acute toxicity study, treatment of the highest dose of DRAE (1 000 mg/kg) had mild liver toxicity indicated by mild focal hemorrhage. Conclusions: DRAE possesses anti-breast cancer properties but at the same time it shows mild toxicity to the liver. The non observable adverse effect dose for DRAE is 500 mg/kg.

    Several diseases are associated to the mosquito-human interaction. Mosquitoes are the carriers of severe and well-known illnesses such as malaria, arboviral encephalitis, dengue fever, chikungunya fever, West Nile virus and yellow fever. These diseases produce significant morbidity and mortality in humans and livestock around the world. The present investigation was undertaken to study the ovicidal, larvicidal and adulticidal activities of crude hexane, ethyl acetate, benzene, chloroform and methanol extracts of root of Asparagus racemosus were assayed for their toxicity against three important vector mosquitoes, viz., Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi (Diptera: Culicidae). The mean percent hatchability of the eggs was observed after 48 h post-treatment. The percent hatchability was inversely proportional to the concentration of extract and directly proportional to the eggs. All the five solvent extracts showed moderate ovicidal activity; however, the methanol extract showed the highest ovicidal activity. The methanol extract of Asparagus racemosus against Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi exerted 100% mortality (zero hatchability) at 375, 300 and 225 ppm, respectively. Control eggs showed 99-100% hatchability. The larval mortality was observed after 24 h of exposure. All extracts showed moderate larvicidal effects; however, the highest larval mortality was found in methanol extract of root of Asparagus racemosus against the larvae of Culex quinquefasciatus, Aedes aegypti and Anopheles stephensi with the LC50 and LC90 values were 115.13, 97.71 and 90.97 ppm and 210.96, 179.92, and 168.82 ppm, respectively. The adult mortality was observed after 24 h recovery period. The plant crude extracts showed dose-dependent mortality. At higher concentrations, the adult showed restless movement for some times with abnormal wagging and then died. Among the extracts tested, the highest adulticidal activity was observed in

    In the present study, we investigate the effect of Korean ginseng root extract (KG) on cisplatin-induced pica in a rat model. Rats were treated with KG before (25, 50, and 100 mg/kg) or after (12.5, 25, and 50 mg/kg) a single intraperitoneal injection of cisplatin (7 and 6 mg/kg, respectively). We examined intake of kaolin and normal food as an indicator of the emetic stimulus every 24 h for 120 h. Changes in body weight, haematology and histopathology were additionally assessed. Pre-treatment with KG (25 and 50 mg/kg) significantly attenuated cisplatin-induced kaolin intake (24, 48, and 72 h) and markedly improved intake of normal food by rats at 48, 72, 96, and 120 h. Cisplatin-induced kaolin intake was markedly decreased upon post-treatment of rats with KG (12.5, 25, and 50 mg/kg) at 24 h. Notably, post-treatment with the lowest KG dose resulted in a significant anti-pica effect and improved food intake until 72 h. The magnitude of body weight reduction was significantly diminished in rats pre-treated/post-treated with 25, 50, and 12.5 mg/kg KG. The anti-pica effects of KG were further confirmed with haematological and histopathological findings. Our findings collectively indicate that KG improves the resistance of rats against emesis.

    Full Text Available Jacaranda decurrens subsp. symmetrifoliolata Farias & Proença (Bignoniaceae is a species traditionally used for the treatment of inflammatory and infectious diseases. Previous findings from our group reported scientifically that J. decurrens has anti-inflammatory efficacy. However, more toxicological studies are needed to support and ensure its safe use. The present study was carried out to evaluate the toxic effects of a prolonged treatment with hydroethanolic root extract of J. decurrens (EJD on hematological, biochemical, and reproductive parameters in adult male rats. The animals received by oral gavage 0; 250; 500; or 1000 mg/kg body weight of EJD for 28 days. After the treatment, biochemical, hematological, histopathological, and reproductive parameters were analyzed. The EJD treatment did not cause adverse effects on body weight gain, feed and water consumption, hematological and biochemical profiles, or histopathological analysis of liver and kidney. Similarly, there were no statistically significant differences in reproductive parameters, such as sperm production, number of sperm in the epididymis, and sperm morphology. These results demonstrate the absence of subacute toxicity as a result of the oral treatment with EJD for 28 days in adult male rats. However, other studies should be performed to evaluate the total safety of this plant.

    Full Text Available Background. Many women experience sexual dysfunction where there are orgasm disorders and sexual difficulties. Ashwagandha (Withania somnifera is a herb known to improve the body’s physical and psychological condition. Objective. The purpose of the study was to determine the efficacy and safety of a high-concentration ashwagandha root extract (HCARE supplementation for improving sexual function in healthy females. Methods. In this pilot study, 50 study subjects were randomized to either (i HCARE-treated group or (ii placebo- (starch- treated group. The subjects consumed either HCARE or placebo capsules of 300mg twice daily for 8 weeks. Sexual function was assessed using two psychometric scales, the Female Sexual Function Index (FSFI Questionnaire and the Female Sexual Distress Scale (FSDS, and by the number of total and successful sexual encounters. Results. The analysis indicates that treatment with HCARE leads to significantly higher improvement, relative to placebo, in the FSFI Total score (p<0.001, FSFI domain score for “arousal” (p<0.001, “lubrication” (p<0.001, “orgasm” (p=0.004, and “satisfaction” (p<0.001, and also FSDS score (p<0.001 and the number of successful sexual encounters (p<0.001 at the end of the treatment. Conclusions. This study demonstrated that oral administration of HCARE may improve sexual function in healthy women. The present study is registered in the Clinical Trial Registry, Government of India, with a number CTRI/2015/07/006045.

    Full Text Available The expression of mitochondrial voltage-dependent anion channels (VDAC mayunderlie the protective effects of Limonium sinense (Girard Ktze root extracts (LSE againstcarbon tetrachloride-induced liver damage. Pretreatment of mice with 100 mg/kg, 200mg/kg or 400 mg/kg LSE significantly blocked the carbon tetrachloride-induced increase inboth serum aspartate aminotransferase (sAST and serum alanine aminotransferase (sALTlevels. Ultrastructural observations by electron microscope confirmed hepatoprotection,showing decreased nuclear condensation, ameliorated mitochondrial fragmentation of thecristae and less lipid deposition. Pretreatment with LSE prevented the decrease of thedisruption of mitochondrial membrane potential (15.3% observed in the liver of the carbontetrachloride-insulted mice, further demonstrating the mitochondrial protection. In addition,LSE treatment (100-400 mg/kg significantly increased both transcription and translation ofVDAC. The above data suggests that LSE mitigates the damage to liver mitochondriainduced by carbon tetrachloride, possibly through regulation of mitochondrial VDAC, one ofthe most important proteins in the mitochondrial outer membrane.

    Objective: Daucus carota L. (Carrot) (Apiaceae) is used in the traditional medicine for the treatment of variety of ailments. The aim of present investigation was to formulate and evaluate wound healing activity of ethanolic extract of Daucus carota L. root on excision wound model and incision wound model. Methods: The soft paraffin based cream containing 1%, 2% and 4% w/w of ethanolic extract of Daucus carota L. (EEDC) root was formulated and evaluated for pharmaceutical parameters such as rheological properties, pH, skin irritation and external characters. Excision wounds sized 300 mm2 and 2 mm depth were used for the study of rate of contraction of wound and epithelization at different time intervals. Incision wounds six centimeter long and two linear-paravertebral incisions were used for the study of tensile strength, total protein and hydroxyproline content measured on 10th day old incision wound. Results: Ethanolic extract of Daucus carota L. root cream formulation when applied topically did not show any sign and symptoms of skin irritation. Animals treated with topical EEDC cream formulation (1%, 2%and 4% w/w) showed significance decrease in wound area, epithelization period and scar width whereas rate of wound contraction significantly increased (P<0.01, P<0.001 and P<0.001 resp.) as compared to control group animals in excision wound model. In incision wound model there was significant increase (P<0.01 and P<0.001) in tensile strength, hydroxyproline content and protein content of animals treated with topical EEDC cream formulation (2% and 4% w/w, respectively). Conclusions: Wound-healing property of ethanolic extract of Daucus carota L. root may be attributed to the various phytoconstituents like flavonoids and phenolic derivatives present in the root and the quicker process of wound healing could be a function of either its antioxidant or antimicrobial potential. The present findings provide scientific evidence to the ethanomedicinal properties of Daucus

    Michaelle G. Santos

    Full Text Available ABSTRACT Eriosema campestre var. macrophylum (Grear Fortunato, Fabaceae, is a native plant of the Brazilian Cerrado and the decoction of its roots has been used by folk medicine for the therapy of inflammatory diseases. In this study we aimed to investigate the effect of the dichloromethane–ethanolic extract of E. campestre roots on the proliferative response of lymphocytes and to examine the profile of IL-2 production. The effect of dichloromethane–ethanolic extract of E. campestre on the proliferation of phytohemagglutinin-stimulated lymphocytes was evaluated by using flow cytometry and the cell supernatants were assayed for IL-2 concentrations by using an enzyme-linked immunosorbent assay. The phytochemical screening of E. campestre roots was performed to determine the main secondary metabolites through chromogenic and precipitation reactions and by using HPLC-PAD. In addition to the presence of subclasses of flavonoids (flavones and flavonols in dichloromethane–ethanolic extract of E. campestre, we observed that the extract induced a concentration-dependent decrease in IL-2 levels on the supernatant of the cell cultures as well as an antiproliferative effect on T lymphocytes, including CD4+ and CD8+ cells. The anti-inflammatory effects attributed to E. campestre by folk medicine may partly be explained by its antiproliferative action on T lymphocytes.

    Medicinal plants have been shown to have both chemopreventive and/or therapeutic effects on cancer and other diseases related to oxidative damage. Moringa oleifera Lam., known in the Hausa and Igala languages of Nigeria as "Zogale" and "Gergedi," respectively, and drumstick in English, is a plant that is used both as food and in folkloric medicine in Nigeria and elsewhere. Different parts of the plant were analyzed for polyphenol content as well as in vitro antioxidant potential. The methanol extract of the leaves of M. oleifera contained chlorogenic acid, rutin, quercetin glucoside, and kaempferol rhamnoglucoside, whereas in the root and stem barks, several procyanidin peaks were detected. With the xanthine oxidase model system, all the extracts exhibited strong in vitro antioxidant activity, with 50% inhibitory concentration (IC(50)) values of 16, 30, and 38 microL for the roots, leaves, and stem bark, respectively. Similarly, potent radical scavenging capacity was observed when extracts were evaluated with the 2-deoxyguanosine assay model system, with IC(50) values of 40, 58, and 72 microL for methanol extracts of the leaves, stem, and root barks, respectively. The high antioxidant/radical scavenging effects observed for different parts of M. oleifera appear to provide justification for their widespread therapeutic use in traditional medicine in different continents. The possibility that this high antioxidant/radical scavenging capacity may impact on the cancer chemopreventive potential of the plant must be considered.

    Objective: To investigate the phytochemical components of Abrus precatorius (A. precatorius) and the in-vitro susceptibility of Salmonella typhi and Shigella dysen-teriae to the aqueous extracts of A. precatorius leaf, seed and root. Methods: The leaf, seed and root of A. precatorius were collected and homogenized separately after drying at 40 °C for seven days in hot-air oven. The aqueous extracts of each of the parts were prepared and subjected to phytochemical screening. Dilutions of 400, 300, 200, 100 mg/mL, of each of the extracts were used for broth dilution in minimum inhibitory concentration (MIC) determination against clinical isolates of Sal-monella typhi and Shigella dysenteriae, while 50, 40, 30, 20, and 10 mg/mL dilutions were used for the agar diffusion test and 100μg/mL and 10μg/mL of gentamycin were used as controls for broth dilution in MIC determination and agar diffusion test, respectively. Results: Qualitative study reveals that tannin, saponins, alkaloids, flavonoids, terpe-noids, steroids and phenols were present in all of the plant parts. The leaf has the highest quantities of tannin and phenol. The root generally showed the lowest quantity of all the compounds. The pathogens were susceptible to aqueous extracts of the leaf, stem and root of A. precatorius at 50 mg/mL. At concentrations of 40, 30 and 20 mg/mL, all the aqueous extracts of A. precatorius showed variation in MIC, but produced no minimum bactericide effect upon subculture. There were variations in diameter of zone of inhibition against the organisms at lower concentrations. Conclusions: These findings suggest that A. precatorius is a valuable source of phyto-chemicals with promising antibacterial activity. Considering this bioactivity, A. precatorius could be probed further for toxicity, and to obtain some novel antibacterial molecules.

    Accumulation of phenolic compounds in cell walls of different plant organs leading to increased lignification is an early defence response of plants against biotic stress. The aim of this work was to delineate occurrence of cell wall-bound (CWB) phenolic compounds in Morinda citrifolia leaves. Alkaline hydrolysis of the cell wall material of leaf tissues yielded 4-coumaric acid (4-CA) as the major bulk of the phenolic compounds in all Morinda germplasms. Next in line was 4-hydroxybenzoic acid. Other phenolics identified were vanillic acid, 4-hydroxybenzaldehyde, vanillin and ferulic acid. Concentrations of all the CWB phenolics were highest in the germplasm CHN-5, followed by the germplasm CHN-1. Incidentally, these two Morinda germplasms recorded lowest incidence of foliar diseases. Significantly higher amounts of 4-CA in combination with other phenolics may be the reasons for lowest incidence of foliar diseases in CHN-5 and CHN-1 germplasms of M. citrifolia.

    Full Text Available Statement of Problem: The main purpose of a root canal treatment is to eliminate the bacteria and their products from the pulp space. Sodium hypochlorite has excellent antibacterial properties, but also some negative features. Purpose: The aim of the present study is to compare the antimicrobial effect of Aloe Vera so-lution with sodium hypochlorite on E.faecalis in the root canals of human extracted teeth. Materials and Method: Sixty human extracted single rooted teeth were selected for this in vitro study. The teeth recruited in this study had no cracks, internal resorption, external resorption and calcification. Enterococcus faecalis was injected in the root canals of all teeth. The teeth were then divided into three groups randomly. Each group consisted of 20 teeth that were all rinsed with one of the following solutions: sodium hypochlorite 2.5%, Aloe vera and normal saline. Subsequent to rinsing, root canals of all teeth were sampled. The samples were cultured and growth of the bacteria was assessed after 48 hours. The number of colonies of the bacteria was then counted. Results: The difference between the inhibitory effect of Aloe vera and normal saline on E.faecalis was not significant according to independent t-test (p= 0.966. The inhibitory effect of sodium hypochlorite on E.faecalis was much greater than that of Aloe vera and normal saline (p< 0.001. Conclusion: Aloe vera solution is not recommended as a root canal irrigator, but future studies are suggested to investigate the antibacterial effect of Aloe vera with longer duration of exposure and as an intra canal medicament.

    It is known that the fruit juice of Morinda citrifolia (M. citrifolia, Noni, Rubiaceae) has various pharmacological effects such as antioxidant or anti-inflammatory activities, which may help the inhibition of ischemic neuronal damage. Here, we examined the effect of the fruit juice of M. citrifolia (Noni juice) on the brain damage caused by ischemic stress in mice. Noni juice was obtained from the mature fruit grown in Okinawa (about 1.5 l/4 kg of fruit; 100% Okinawa Noni juice (ONJ). Male ddY mice were supplied with 3% or 10% juice in the drinking water for 7 d, and compared to the control group. On the 7th day, mice were subjected to 2 h of middle cerebral artery occlusion (MCAO). Interestingly, the intake of juice reduced the infarct volume as analyzed by 2,3,5-triphenyltetrazolium chloride (TTC) staining on the 3rd day of MCAO when compared to the control group. Furthermore, we found that the neurological deficit scores (NDS) were decreased after the reperfusion in the juice-supplied mice. On the other hand, the intake of juice did not affect the expression levels of antioxidant such as Cu/Zn superoxide dismutase. The present study suggests that Noni juice may have a preventive effect against cerebral ischemic stress, while further studies are needed to explain the detailed mechanism.

    In this paper, we present a novel surface imprinting technique for the preparation of molecularly imprinted polymers/multi-walled carbon nanotubes (MIPs/MWNTs) for extraction of emodin from kiwi fruit root. The MIPs/MWNTs were characterised by scanning electron microscopy (SEM) and Fourier transform-infrared spectroscopy (FT-IR). The properties involving adsorption dynamics, static adsorption, and selective recognition capacity were evaluated. The MIPs/MWNTs exhibited good site accessibility in which it only took 60 min to achieve adsorption equilibrium and highly selective recognition for the template emodin. Furthermore, the performance of the MIPs/MWNTs as solid phase extraction (SPE) material was investigated in detail. The proposed MIPs/MWNTs-SPE procedure for emodin exhibited satisfactory recoveries ranging from 89.2% to 93.8% for real samples. It was used for the purification and enrichment of emodin from kiwi fruit root successfully.

    Biotic and abiotic stresses can inhibit plant growth, resulting in losses of crop productivity. However, moderate adverse stress can promote the accumulation of valuable natural products in medicinal plants. Elucidating the underlying molecular mechanisms thus might help optimize the variety of available plant medicinal materials and improve their quality. In this study, Salvia miltiorrhiza hairy root cultures were employed as an in vitro model of the Chinese herb Danshen. A comparative proteomic analysis using 2-dimensional gel electrophoresis and MALDI-TOF-MS was performed. By comparing the gel images of groups exposed to the stress of yeast extract (YE) combined with Ag(+) and controls, 64 proteins were identified that showed significant changes in protein abundance for at least one time point after treatment. According to analysis based on the KEGG and related physiological experimental verification, it was found that YE and Ag(+) stress induced a burst of reactive oxygen species and activated the Ca(2+)/calmodulin signaling pathway. Expression of immune-suppressive proteins increased. Epidermal cells underwent programmed cell death. Energy metabolism was enhanced and carbon metabolism shifted to favor the production of secondary metabolites such as lignin, tanshinone and salvianolic acids. The tanshinone and salvianolic acids were deposited on the collapsed epidermal cells forming a physicochemical barrier. The defense proteins and these natural products together enhanced the stress resistance of the plants. Since higher levels of natural products represent good quality in medicinal materials, this study sheds new light on quality formation mechanisms of medicinal plants and will hopefully encourage further research on how the planting environment affects the efficacy of herbal medicines.

    Croton membranaceus aqueous root extract (CMARE) is among the widely used phytotherapeutics in Ghana for the management of benign prostatic hyperplasia (BPH) and prostate cancer. However, the mechanism of action of CMARE remains to be elucidated. This study aimed to establish whether apoptosis is involved in the antiproliferative effect of CMARE on human BPH-1 cells. We determined the effect of treatment with 0, 1, 3, and 5 mg/mL CMARE for 24, 48, and 72 h on the viability and morphology of BPH-1 cells using the MMT assay and phase-contrast microscopy, respectively. We examined the apoptosis-inducing effects of CMARE after 48 h at the cellular level using Hoescht 33258 and JC-1 dye staining and flow cytometry analysis. We performed reverse transcription polymerase chain reaction and Western blotting to confirm the apoptotic effects of CMARE at the molecular level. CMARE induced a significant dose-dependent inhibition in the proliferation of BPH-1 cells (P < 0.05) and an alteration in their morphology and a reduction their density. Furthermore, CMARE induced dose-dependent staining of the nuclear chromatin, significant DNA fragmentation with G₀/G₁ sub-diploid cells (P < 0.01), and loss of the mitochondrial membrane potential in the treated cells compared to the controls after 48 h (P < 0.01). Additionally, while CMARE induced a significant upregulation of the mRNA and protein levels of Bax, those of Bcl2 did not change significantly. Therefore, induction of mitochondria-dependent apoptosis of BPH-1 cells may be a possible mechanism of action of CMARE.
