    Methanolic extracts of Pterocarpus marsupium Roxb (P. marsupium) and Ocimum sanctum Linn (O. sanctum) were prepared separately and then administered to both non-diabetic and alloxan induced diabetic adult female Wistar rats as a mixture of both at a dosage of 500mg/kg body weight, and its effect was checked on serum and tissue lipids together with corticosterone, estrogen and progesterone profile. Further, tissue load of metabolites (cholesterol), enzymatic and non-enzymatic antioxidant status together with lipid peroxidation levels and serum markers of hepatic and renal damage were also assessed. Results of the present study strongly support the possibility of this herbal combination in humans to meet the objective of achieving a holistic amelioration and cure of diabetes as, the herbal extract mixture of P. marsupium and O. sanctum has succeeded in not only rectifying dyslipidemia but also in restoring the endogenous antioxidant levels to the pre diabetic status. Herbal preparations are ideal candidates of choice and in this context, the present combination of P. marsupium and O. sanctum provides compelling evidence for a holistic efficacy in amelioration of associated diabetic manifestations/dysregulations.

    The antidiabetic activity of various subfractions of the alcohol extract of the bark of Pterocarpus marsupium Roxb. was evaluated in alloxan-induced diabetic rats. The effect of these extracts on lipid profile and liver function tests were also assessed to evaluate their activity in controlling diabetes related metabolic alterations. The parameters measured were plasma glucose, total protein, cholesterol, triglycerides, alkaline phosphatase, SGOT and SGPT. The results indicate the effective role of Pterocarpus marsupium on the above mentioned parameters indicating that Pterocarpus marsupium can also control the diabetes related metabolic alterations apart from controlling the glucose levels. Among the fractions tested the butanol subfraction was found to be more active in comparison with other subfractions. It can be concluded that the butanol subfraction of the alcohol extract of Pterocarpus marsupium exhibits significant antidiabetic activity and corrects the metabolic alterations in diabetic rats and this activity may resemble insulin-like properties.

    Diabetes mellitus is a complex chronic disease characterized by hyperglycemia, which via several mechanism leads to an increase in production of reactive oxygen species (ROS) leading to various secondary complications. Thus, a drug having both antidiabetic and antioxidant properties would have great therapeutic value for overcoming the oxidative load in diabetes. The present study was aimed at extensively evaluating the antioxidant properties of an anti-diabetic plant extract of stem bark of Pterocarpus marsupium using various in vitro radical scavenging assays as well as by using liver slice cultures as a model system. Our results demonstrate that the whole aqueous extract showed high antioxidant activity in all different assays used and also protected mitochondria against oxidative damage. Ethanol was used as an inducer of oxidative stress in liver slice culture and cytotoxicity was estimated by quantitating release of cytotoxicity marker enzymes such as lactate dehydrogenase (LDH). Additionally, levels of antioxidant enzymes (AOEs) namely superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase were also estimated. The whole aqueous extract significantly reduced LDH release along with reduction of lipid peroxidation compared to ethanol treated slices. These results indicate that the P. marsupium extract may serve as a potential source of natural antioxidant for treatment of diabetes.

    The purpose of the present study is to analyse the influence of Pterocarpus marsupium methanolic extract and isolated Pterocarpus marsupium isoflavone on a battery of cellular targets Glut-4, PPAR gamma and PI3 kinase. Pterocarpus marsupium is an anti-diabetic plant indigenous to South India. Sequential extraction performed with different solvents were analysed for glucose uptake activity at each step. Fraction-9 showing maximum glucose activity on glucose uptake was purified by column chromatography and the structure was elucidated as 7-O-alpha-L-rhamnopyranosyl oxy-4'-methoxy-5-hydroxy isoflavone using NMR and mass spectroscopy. The significant glucose uptake showed by Pterocarpus marsupium crude and pure was comparable with insulin and rosiglitazone. Elevation of Glut-4 and PPARgamma gene expression in parallel with glucose uptake supported the in vitro glucose uptake activity of Pterocarpus marsupium methanolic extract and Pterocarpus marsupium isoflavone. The inhibitory effect of cycloheximide on Pterocarpus marsupium methanolic extract and Pterocarpus marsupium isoflavone-mediated glucose uptake suggested that new protein synthesis is required for elevated Glut-4 protein expression. PI3 kinase plays an important role in glucose transport and activated by Pterocarpus marsupium methanolic extract but not the isolated pure isoflavone. Therefore, we postulate that the isoflavone from Pterocarpus marsupium may activate glucose transport by a PI3 kinase independent pathway, which require further analysis.

    Full Text Available A method was developed for optimization of In vitro germination of an economically important timber-yielding multipurpose tree, Pterocarpus marsupium Roxb. The seeds inoculated in different orientation on different strengths of MS medium without any hormones showed varied response to the seed positions. The seeds inoculated on half strength medium in horizontal position recorded to produce a maximum germination (78.23%, shoot number (0.86 and root number (7.99. However, a maximum of shoot length of 3.67 cm was recorded in the quarter strength medium in the seeds inoculated in vertical down position, which was significantly higher than other media strength and positions. Our results indicate that the seed orientation including medium strength have tremendous effect on germination and seeds inoculated horizontally on half strength MS medium can be utilized to enhance In vitro seed germination of Pterocarpus marsupium.

    Long-term complications are frequently encountered in diabetes mellitus and are difficult to treat. This study was undertaken to assess the effect of three antidiabetic plants on the development of cataract in rats. An aqueous extract of Pterocarpus marsupium Linn bark (PM, Hindi name: Vijaysar) (1 g kg(-1) day(-1)), Ocimum sanctum Linn leaves (OS, Hindi name, Tulsi) (200 mg kg(-1) day(-1)) and alcoholic extract of Trigonella foenum-graecum Linn seeds (FG, Hindi name, Methi) (2 g kg(-1) day(-1)) were given to alloxan (120 mg kg(-1)) diabetic rats until the development of cataract. Serum glucose and body weight were monitored at regular intervals while cataract was examined through naked eye as well as slit lamp at 75, 100 and 115 days after alloxan administration. Administration of all the three plant extracts exerted a favorable effect on body weight and blood glucose, the effects were best with PM followed by FG and OS. On the course of cataract development, PM followed by FG exerted anti-cataract effect evident from decreased opacity index while OS failed to produce any anti-cataract effect in spite of significant antihyperglycemic activity.

Materials and Methods: The effect of heart wood extract of P. marsupium on wound healing has been studied in diabetic and normal animals. The effect has also been compared with standard (mupirocin ointment application. In the absence of specific animal model for cutaneous diabetic wound healing, we have used common model of wound healing (excision wound model in animals having diabetes (by administration of alloxan monohydrate 120 mg/kg i.p.. Statistics Analysis: Data were analyzed by using one-way ANOVA, followed by Tukey′s post hoc tests, using the Graph Pad Software (5.0 demo version, and P value <0.05 was considered to be significant. Results and Conclusion : Rats treated with 200 mg/kg/day of P. marsupium heart wood extract had high rate of wound contraction, significantly decreased epithelization period, and significant increase in dry weight, wet weight, and hydroxyproline content of the granulation tissue when compared with the diabetic control and normal control groups. Wound contraction together with increased tensile strength and hydroxyproline content support the use of P. marsupium heart wood extract in the management of wound healing in normal and diabetic rats.

    The present study was undertaken to evaluate cardiotonic activity of aqueous extract of heartwood of P. marsupium. This plant species contains 5,7,2-4 tetrahydroxy isoflavone 6-6 glucoside which are potent antioxidant and are believed to prevent cardiovascular diseases. Cardiotonic effect of aqueous extract of heartwood of P. marsupium was studied by using isolated frog heart perfusion technique (IFHP). Calcium free Ringer solution was used as vehicle for administration of aqueous extract of P. marsupium as a test extract and digoxin as a standard. A significant increase in height of force of contraction (positive inotropic effect) and decrease in heart rate (negative chronotropic effect) at a very low concentration (0.25 mg/ml) was observed with test extract as compared to the same dose of a standard digoxin. The present results indicated that a significant increase in height of force of contraction with decrease in heart rate was observed as the dose of test extract increased. The test extract produced cardiac arrest at 4 mg/ml, a higher concentration, as compared to standard, digoxin (0.5 mg/ml). Compared to digoxin, a drug with narrow therapeutic window, P. marsupium showed wide therapeutic window.

    We investigated the effect of seed mass on emergence, seed-ling survival and growth of Pterocarpus marsupium Roxb., a medium to large, commercially valuable and deciduous tree species. Among the three size classes viz. small (10-12 mm), medium (13-15 mm) and large (16-17 mm), the maximum proportion of seed by number (54.12%) and dry weight (51.87%) was recorded in the medium size seed class. Seed length and seed width were greatest in the large seed class (16.50 mm, 7.33 mm) followed by medium (13.50 mm, 5.60 mm) and small (11.37 mm, 3.66 mm). Similarly, hundred seed weight (100 sw) varied from a maximum of 12.92 g in the large seed class to intermediate 10.95 g in the medium seed class and minimum of 7.02 g in the small seed class. The large seed size showed maximum emergence and shoot length over the medium and small seed class. After six months of growth, significant variations due to seed size were also observed for the growth and dry weight of P. marsupium seedlings. Seedling vigour, expressed in terms of height, collar diameter, number of leaves and dry biomass, was sig-nificantly affected by seed class. Seedlings that emerged from large seeds showed better growth and produced heavier seedlings as compared to medium and small seeds.

    This study was designed to investigate the effect of aqueous extract of Pterocarpus marsupium Roxb. on elevated inflammatory cytokine, tumor necrosis factor (TNF)-α in type 2 diabetic rats. Type 2 diabetes was induced by administering streptozotocin (90 mg/kg, i.p.) in a neonatal rat model. Aqueous extract of P. marsupium at a dose of 100 and 200 mg/kg was given orally to desired group of animals for a period of 4 weeks. After 4 weeks of drug treatment, parameters such as fasting blood glucose, postprandial blood glucose, and TNF-α in serum were analyzed. Aqueous extract of P. marsupium at both doses, i.e., 100 and 200 mg/kg, decreased the fasting and postprandial blood glucose in type 2 diabetic rats. The 200 mg/kg had more pronounced effect on postprandial hyperglycemia. The drug also improved the body weight of diabetic animals. Cytokine TNF-α was found to be elevated in untreated diabetic rats due to chronic systemic inflammation. The aqueous extract at both doses significantly (P < 0.001) decreased the elevated TNF-α level in type 2 diabetic rats. Modulation of cytokine TNF-α by the rasayana drug P. marsupium is related with its potential anti-diabetic activity.

    Full Text Available Bactericidal potential of methanolic extract of stem bark (Apical bark, middle bark and Mature bark of Pterocarpus marsupium was evaluated with respect to pathogenic bacteria Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoneae, Salmonella typhi, Proteus mirabilis and Micrococcus sp. The methanolic extract of apical stem bark was effective than the middle bark and mature bark in inhibiting the growth of all bacteria. The bacterium Staphylococcus aureus was most sensitive among all the bacterial species studied. Preliminary phytochemical analysis revealed the presence of alkaloids, glycosides,flavonoids, flavonols, phenols and terpenoids. Saponins were absent in all the bark samples.The concentrations of these phytoconstituents was higher in the apical stem bark than the middle and mature stem bark. The percent extract yield was maximum in apical stem bark. Thus, in the pharmacological point of view, it is important to study the biochemistry of apical bark in order to isolate and screen the new pharmacological active principals which can be useful in designing of new drugs active against various infectious micro- rganisms like bacteria, fungi and viruses etc.

    The renewed interest in plant-derived drugs has led to an increased need for efficient extraction methods. The present investigation was an attempt to evaluate and compare the conventional methods of extraction with non conventional methods of extraction, such as ultrasonic-assisted extraction (UAE) and microwave-assisted extraction (MAE) methods. Pterocarpus marsupium Roxb. has been reported to contain bioactive phytochemicals, e.g., pterostilbene (3',5'-dimethoxy-4-stilbenol). The results showed that among the conventional extraction methods, percolation gave the highest yield. The non conventional methods were optimized. The extraction yield was the highest in case of MAE. The phytochemical screening of the extracts indicated similar groups of compounds in all the extracts. The thin layer chromatography showed the presence of pterostilbene in the extracts obtained by using percolation, MAE and UAE. In these extracts the quantification of pterostilbene was conducted by high performance liquid chromatography and the method was validated. The MAE method extracted significantly higher amount of pterostilbene.

    Alzheimer's disease (AD), the most common form of dementia, is characterized by the loss of normal functions of brain cells and neuronal death, ultimately leading to memory loss. Recent accumulating evidences have demonstrated the therapeutic potential of anti-diabetic agents, such as dipeptidyl peptidase-4 (DPP-4) inhibitors, for the treatment of Alzheimer's disease (AD), providing opportunities to explore and test the DPP-4 inhibitors for treating this fatal disease. Prior studies determining the efficacy of Pterocarpus marsupium (PM, Fabaceae) and Eugenia jambolana (EJ, Myrtaceae) extracts for ameliorating type 2 diabetes have demonstrated the DPP-4 inhibitory properties indicating the possibility of using of these extracts even for the treating AD. Therefore, in the present study, the neuroprotective roles of PM and EJ for ameliorating the streptozotocin (STZ) induced AD have been tested in rat model. Experimentally, PM and EJ extracts, at a dose range of 200 and 400mg/kg, were administered orally to STZ induced AD Wistar rats and cognitive evaluation tests were performed using radial arm maze and hole-board apparatus. Following 30 days of treatment with the extracts, a dose- and time-dependent attenuation of AD pathology, as evidenced by decreasing amyloid beta 42, total tau, phosphorylated tau and neuro-inflammation with an increase in glucagon-like peptide-1 (GLP-1) levels was observed. Therefore, PM and EJ extracts contain cognitive enhancers as well as neuroprotective agents against STZ induced AD. Copyright © 2014 Elsevier B.V. All rights reserved.

    Insulin resistance (hyperinsulinaemia) is now recognized as a major contributor to the development of glucose intolerance, dyslipidaemia and hypertension in non-insulin-dependent diabetes mellitus (NIDDM) patients. Sedentary lifestyle, consumption of energy-rich diet, obesity, longer lifespan, etc., are important reasons for this rise (J. R. Turtle, Int J Clin Prac 2000; 113: 23). Aqueous extracts of Pterocarpus marsupium Linn bark (PM), Ocimum sanctum Linn leaves (OS) and Trigonella foenumgraecum Linn seeds (FG) have been shown to exert hypoglycaemic/antihyperglycaemic effect in experimental as well as clinical setting. As no work has been carried out so far to assess the effect of PM, OS and FG on fructose-induced hyperglycaemia, hyperinsulinaemia and hypertriglyceridaemia, we undertook this study to assess whether these extracts attenuate the metabolic alteration induced by fructose-rich diet in rats. Five groups of rats (eight each) were fed chow diet, 66% fructose diet, 66% fructose diet + PM leaves extract (1 g/kg/day), 66% fructose diet + OS leaves extract (200 mg/kg/day) and 66% fructose diet + FG seeds extract (2 g/kg/day) for 30 days. Fructose feeding to normal rats for 30 days significantly increased serum glucose, insulin and triglyceride levels in comparison with control. Treatment with all the three plants extract for 30 days significantly lowered the serum glucose levels in comparison with control group. However, only PM extract substantially prevented hypertriglyceridaemia and hyperinsulinaemia, while OS and FG had no significant effect on these parameters. Results of this study, in addition to previous clinical benefits of PM seen in NIDDM subjects, are suggestive of usefulness of PM bark (Vijayasar) in insulin resistance, the associated disorder of type 2 diabetes; however, OS and FG may not be useful. Though several antidiabetic principles (-epicatechin, pterosupin, marsupin and pterostilbene) have been identified in the PM, yet future studies

    Full Text Available A method was developed for optimization of In vitro germination of an economically important timber-yielding multipurpose tree, Pterocarpus marsupium Roxb. The seeds inoculated in different orientation on different strengths of MS medium without any hormones showed varied response to the seed positions. The seeds inoculated on half strength medium in horizontal position recorded to produce a maximum germination (78.23%, shoot number (0.86 and root number (7.99. However, a maximum of shoot length of 3.67 cm was recorded in the quarter strength medium in the seeds inoculated in vertical down position, which was significantly higher than other media strength and positions. Our results indicate that the seed orientation including medium strength have tremendous effect on germination and seeds inoculated horizontally on half strength MS medium can be utilized to enhance In vitro seed germination of Pterocarpus marsupium.

    In this study, an extract of Pterocarpus marsupium Roxb. containing pterostilbene has been evaluated for its PGE2-inhibitory activity in LPS-stimulated PBMC. In addition, the COX-1/2 selective inhibitory activity of P. marsupium (PM) extract was investigated. Biological activity, as well as safety of PM extract was evaluated in healthy human volunteers. PM extract, pterostilbene and resveratrol inhibited PGE2 production from LPS-stimulated human peripheral blood mononuclear cells (PBMC) with IC50 values of 3.2 +/- 1.3 microg/mL, 1.0 +/- 0.6 microM and 3.2 +/- 1.4 microM, respectively. When pterostilbene content of PM extract is calculated, PGE2 production inhibition of PM extract is comparable to PGE2 production inhibition of purified pterostilbene. Furthermore, in a COX-1 whole blood assay (WBA) PM extract was not effective while in a COX-2 WBA, PM extract decreased PGE2 production indicating COX-2 specific inhibition. In healthy human volunteers, the oral use of 450 mg PM extract did not decrease PGE2 production ex vivo in a WBA. Pterostilbene levels in serum were increased, but were 5-fold lower than the observed IC50 for PGE2 inhibition in LPS-stimulated PBMC. No changes from base-line of the safety parameters were observed and no extract-related adverse events occurred during the study. In conclusion, this is the first study to describe the selective COX-2 inhibitory activity of a Pterocarpus marsupium extract. Moreover, the PGE2 inhibitory activity of PM extract was related to its pterostilbene content. In humans, 450 mg PM extract resulted in elevated pterostilbene levels in serum, which were below the active concentration observed in vitro. In addition, short-term supplementation of 450 mg PM extract is considered to be a safe dose based on the long history of use, the absence of abnormal blood cell counts and blood chemistry values and the absence of extract-related adverse events. This strongly argues for a dose-finding study of PM extract in humans to

    The crude powder, ethanolic extract and aqueous, chloroform, hexane and n-butanol soluble fractions of ethanolic extract of heart wood of P. marsupium showed marked improvement on oral glucose tolerance post sucrose load in normal rats. All these fractions except aqueous fraction showed improvement on oral glucose tolerance post sucrose load on streptozotocin (STZ)-induced diabetic rats. The crude powder, ethanolic extract and hexane and n-butanol fractions showed marked decline in blood glucose level on STZ-induced diabetic rats. The ethanolic extract (100 mg/kg body weight) when given to STZ-induced diabetic rats for 10 consecutive days declined blood glucose, improved OGTT and increased their serum insulin levels. The ethanolic extract also showed marked improvement on oral glucose tolerance on high fat-low dosed STZ-induced diabetic rats and neonatally STZ treated rats. The ethanolic extract of P. marsupium also showed marked antidyslipidemic effects on high fat diet fed Syrian golden hamsters. Altered renal and hepatic function markers and serum insulin levels of high fat diet fed-low dosed STZ-treated diabetic rats were also found towards normalization when these animals were treated with ethanolic extract of P. marsupium for 28 consecutive days. The four out of five phenolic C-glycosides isolated from n-butanol fraction of ethanolic extract of P. marsupium enhanced glucose uptake by skeletal muscle cells (C2C12) in a dose dependent manner. It may primarily be concluded that phenolic-C-glycosides present in P. marsupium heart wood are the phytoconstituents responsible for the antihyperglycemic activity and validate the claim of antidiabetic activity of heart wood of P. marsupium.

    The Indian traditional system of medicine prescribed plant therapies for diseases including diabetes mellitus called madhumeh in Sanskrit. One such plant mentioned in Ayurveda is Pterocarpus marsupium (PM). In the present study, aqueous extract of PM (1 g/kg PO) was assessed for its effect on glycogen levels of insulin dependent (skeletal muscle and liver), insulin-independent tissues (kidneys and brain) and enzymes such as glucokinase (GK), hexokinase (HK), and phosphofructokinase (PFK). Administration of PM led to decrease in blood glucose levels by 38 and 60% on 15th and 30th day of the experiment. Liver and 2-kidney weight expressed as percentage of body-weight was significantly increased in diabetics (p < 0.0005) vs. normal controls and this alteration in the renal weight (p < 0.0005) but not liver weight was normalized by feeding of PM extract. Renal glycogen content increased by over 10-fold while hepatic and skeletal muscle glycogen content decreased by 75 and 68% in diabetic controls vs. controls and these alteration in glycogen content was partly prevented by PM. Activity of HK, GK and PFK in diabetic controls was 35,50 and 60% of the controls and PM completely corrected this alteration in PFK and only partly in HK and GK.

    Pterocarpus marsupium Roxb. (PM) is an Ayurvedic traditional medicine well known for its antidiabetic potential. To fractionate the antidiabetic constituent(s) of the aqueous of extract of PM hardwood (PME). Bio-assay methods including, insulin secretion from mouse pancreas and glucose uptake by mouse skeletal muscle, were used to determine and fractionate the antidiabetic activity of PME. Results obtained from the in vitro experiments were then verified by examining the effect of PME on glucose clearance in normoglycemic, non-diabetic sheep in vivo. Exposure of mouse pancreatic and muscle tissues to PME stimulated the insulin secretion and glucose uptake, respectively, in a concentration-dependent manner. PME-mediated muscle glucose uptake was not potentiated in the presence of insulin indicating that PME acts via pathways which are utilized by insulin. Bio-assay-guided fractionation of PME yielded a high molecular weight fraction which had potent antidiabetic properties in vitro, and in in vivo. Our findings, we believe for the first time, provide novel insights for the antidiabetic constituents of PM and demonstrate that a high molecular weight constituent(s) of PM has potent insulinotrophic and insulin-like properties.

    Pterostilbene, a dimethyl ester derivative of resveratrol, may act as an cytotoxic and hence as an anti-cancer agent. The present study was conducted to test the anti-cancer activity of pterostilbene purified from Pterocarpus marsupium on breast (MCF-7) and prostate (PC3) cancer cell lines. The purified pterostilbene was found to cause apoptosis in both the cell lines, which was marked by DNA fragmentation, formation of apoptotic bodies and membrane distortions. Apoptosis probably was due to the production of reactive oxygen species in MCF-7 and nitric oxide over production in PC3 cells. Even the drug detoxifying anti-oxidant enzymes could not nullify the effect of pterostilbene as required by the cancer cells for survival. Pterostilbene was found to inhibit the cell proliferating factors like Akt, Bcl-2 and induced the mitochondrial apoptotic signals like Bax, and the series of caspases. It also inhibited Matrix metalloproteinase 9 (MMP9) and alpha-methylacyl-CoA recemase (AMACR), two very well known metastasis inducers. In conclusion, pterostilbene has multiple target sites to induce apoptosis. Hence, after proper validation it can be used as a potential agent for the cure of breast and prostate cancer.

    The aim of the study was to evaluate the effect of Pterocarpus marsupium (PM) on acetic acid (AA)-induced ulcerative colitis (UC) in rats. The rats were divided into five groups, each having six rats. PM extract 100 mg and 200 mg/kg was given orally to groups four and five, respectively, and standard drug sulfasalazine (100 mg/kg, p.o) to group three. Group two served as UC control animals, and group one control animals received vehicle for 7 days. UC was induced by administering AA (3 % v/v of 2 ml) to all the animals except group one. After 72 h, the animals were killed and the colon was dissected out for microscopic, clinical evaluation, histopathological study and biochemical estimation. PM (100 and 200 mg/kg)-treated group had significantly reduced colon inflammation and mucosal damage. The treatment also normalized the altered antioxidant enzyme levels (LPO, SOD and GSH). Histopathological studies support the effect. The protective effect of PM may be due to antiinflammatory and antioxidant properties.

    The main aims of the study were to evaluate the phytochemical constituents and to study the antioxidant, antimicrobial, antidiabetic, anti-inflammatory, and analgesic activities of extracts from stem wood of Pterocarpus marsupium. Ethanol, acetone and isopropyl alcohol (IPA) (1:1) extracts of stem wood of P. marsupium were subjected to phytochemical screening and analysis of biological activities from August 2015 to January 2016. The antioxidant assay was carried out using 2, 2-diphenyl-1-picrylhydrazyl scavenging method, antimicrobial activity testing by cup diffusion method, antidiabetic test evaluation by oral glucose tolerance test in mice, anti-inflammatory effect was evaluated by hind paw edema method in mice and analgesic test evaluation by a chemical writhing method in mice. The results of the study revealed that P. marsupium is a source of various phytoconstituents such as alkaloids, glycosides, saponins, tannins, proteins, carbohydrates, cardiac glycosides, flavonoids, and terpenoids. Both the acetone and IPA extract as well as the ethanol extract of stem wood of P. marsupium exhibited a dose-dependent antioxidant activity. Acetone and IPA extract showed antibacterial activity against Gram-positive bacteria, while the ethanolic extract was found to possess antidiabetic activity. The antidiabetic activity of the extract was found to be time and dose-dependent. Similarly, the acetone and IPA extract was found to have anti-inflammatory activity, which was also time and dose-dependent. Furthermore, the ethanolic extract showed analgesic activity, which was dose-dependent. The ethanolic extract was found to be nontoxic. Thus, this study laid sufficient background for the further research on extracts from stem wood of P. marsupium for identification, subsequent purification and isolation of compounds having antibacterial, antidiabetic, anti-inflammatory, and analgesic activities.

    Pterocarpus marsupium (PM) (Leguminosae), Eugenia jambolana (EJ) (Myrtaceae) and Gymnema sylvestre (GS) (Asclepiadaceae) are the most important medicinal plants in the Indian system of traditional medicine for the treatment of hyperglycemia. Dipeptidyl peptidase-4 (DPP-4) inhibitors are the emerging class of anti-diabetic agents. However, only few compounds are commercially available. Therefore, in the present study we tried to explore the naturally occurring PM, EJ and GS semi-standardized extracts for their potential DPP-4 inhibition in vitro and in vivo. DPP-4 inhibition was evaluated by in vitro inhibitory assay, and enzyme kinetics were calculated using one-phase exponential decay equation. Glucose load (2 g/kg) was administered to control and diabetic rats 30 min following extract administration (100, 200 and 400 mg/kg) orally once, and blood samples were withdrawn at 0, 0.5, 1, 1.5, 2 and 3 h to measure plasma active glucagon-like peptide-1 (GLP-1) levels. PM and EJ inhibit DPP-4 potently with IC50 values of 273.73 ± 2.96 and 278.94 ± 6.73 µg/mL, respectively, compared to GS (773.22 ± 9.21 µg/mL). PM, EJ and GS exhibit long duration of action with enzyme inhibitory half-lives of 462.3, 317.2 and 153.8 min, respectively. Extracts significantly increase GLP-1 levels compared to negative control groups and peak GLP-1 level was observed at 2 h for PM and EJ, whereas for GS it was at 1.5 h Taken together, results suggest the extracts may have potent DPP-4 inhibitory action, and their hypoglycemic action attributed through an increase in plasma active GLP-1 levels.

    Pterocarpus marsupium is a well-known plant due to its healing properties, in particular, the use of its aqueous extract is able to reduce blood sugar levels and blood triglyceride concentrations. Although this plant has already been widely studied, a complete characterization of its aqueous extract has not been reported. The present study deals with the characterization of the aqueous extract of P. marsupium in order to obtain a full fingerprint of the volatile and nonvolatile constituents. The volatile constituents were identified by CG-MS, whereas the nonvolatile fraction was characterized by UHPLC-MS/MS using a nontarget approach. Several compounds were identified, in particular, polyphenolic species belonging to the class of proanthocyanidins. Cytotoxicity tests were carried out on four different cancer cell lines and three different non-tumoral cell lines. Preliminary results indicate a selective cytotoxicity of the aqueous extract towards the cancer cells. The potential cytotoxicity due to the presence of metals in the aqueous extract was ruled out by testing an aqueous mixture of the metals at the same concentration found in the P. marsupium extract.

    Rising popularity of phytomedicines in various diseased conditions have strengthened the significance of plant-research and evaluation of phytoextracts in clinical manifestations. Pterocarpus marsupium Roxb., a medicinal plant, known for its anti-oxidant and anti-diabetic activity is a rich source of phytochemicals with antihyperglycemic and antihyperlipidemic activities. However, its possible role in diabetic complications is not evaluated yet. The present study explores the possible role of alcoholic extract of heartwood of P. marsupium in the treatment of long-term diabetic complications. The alcoholic extract of P. marsupium was evaluated for advanced glycation-end-products formation, erythrocyte sorbitol accumulation and rat kidney aldose reductase enzyme inhibition at the concentration of 25-400 μg/ml using in-vitro bioassays. Also the phytoextract at the concentration of 10-320 μg/ml was evaluated for its antioxidant potential by in-vitro antioxidant assays which includes, determination of total phenol content; reducing power assay; nitric oxide scavenging activity; superoxide radical scavenging activity; total antioxidant capacity; total flavonoid content; DPPH scavenging activity; and hydrogen peroxide scavenging activity. The alcoholic extract of P. marsupium across varying concentrations showed inhibitory effect as evident by IC50 on advanced glycation-end-products formation (55.39 μg/ml), sorbitol accumulation (151.00 μg/ml) and rat kidney aldose reductase (195.88 μg/ml). The phytoextract also exhibited high phenolic and flavonoid contents with promising antioxidant potential against the antioxidant assays evaluated. The present investigation suggests that the phytoextract showed prominent antioxidant, antiglycation property and, inhibited accumulation of sorbitol and ALR enzyme, thus promising a beneficial role in reducing/delaying diabetic complications.

    The aim of the present study was to assess the anti-diabetic activity of Pterocarpus marsupium Roxb. heartwood in alloxan induced diabetic rats using extracts obtained by optimized conventional and non conventional extraction methods. Aqueous and ethanol extracts of Pterocarpus marsupium heartwood were prepared by conventional methods (infusion, decoction, maceration and percolation) and non conventional methods, such as ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE). The crude aqueous extracts were administered orally to both normal and alloxan induced male albino rats (Sprague-Dawley strain). The experimental set up consisted of 48 male albino rats divided into 6 groups: Normal control, diabetic control (sterile normal saline, 1 ml/100 g body weight), standard (gliclazide, 25 mg/1000g of body weight), groups 4-6 (crude aqueous percolation, optimized UAE and MAE extract, 250 mg/1000g of body weight). In acute treatment, the reduction of blood glucose level was statistically significant with the oral administration of UAE and percolation aqueous extracts to the hyperglycemic rats. In sub-acute treatment, the UAE aqueous extract led to consistent and statistically significant (p<0.001) reduction in the blood glucose levels. There was no abnormal change in body weight of the hyperglycemic animals after 10 days of administration of plant extracts and gliclazide. This study justifies the traditional claim and provides a rationale for the use of Pterocarpus marsupium to treat diabetes mellitus. The antidiabetic activity of Pterocarpus marsupium can be enhanced by extracting the heartwood by non conventional method of UAE.

    The need for new therapeutics for wound healing has encouraged the drive to examine the nature and value of plant products. Ayurveda, the Indian traditional system of medicine, mentions the values of medicinal plants for wound healing. One of these is Pterocarpus santalinus. This article describes a pharmacological study to evaluate its toxicity as well as wound-healing potential in animal studies. Powder made from the wood of the P. santalinus tree was used to make up an ointment in a petroleum jelly base. No toxic effects were observed in 72 hours. Studies were done on punch and burn wound models on normal and diabetic rats using the test ointment, untreated and vehicle controls, and standard therapy. Physical and biochemical measurements were made. The test ointment-treated wounds healed significantly faster. On healing, collagenesis and biochemical measurements yielded supportive data. These studies permit the conclusion that the P. santalinus ointment is safe and effective in treating acute wounds in animal models.

    Oxidative stress is believed to be a pathogenic factor in the development of diabetic complications. In the present study, we aimed to evaluate the effects of different fractions of heart wood of Pterocarpus marsupium on antioxidant enzyme like protein thiols and also check the efficacy of the extract for the protection of the renal function in alloxan induced diabetic rats. The present study also investigates the levels of liver glycogen which are considered as the best biomarker for assaying the hypoglycemic activity of any drug. Diabetes was induced by administering alloxan dissolved in saline, while the normal control group was given propylene glycol. Diabetes induced animals were randomly assigned into different groups. Blood samples were collected from all the experimental and control groups. Estimation of urea, uric acid and creatinine along with protein thiols was made on day 30 only. At the end, all the animals were sacrificed to collect liver tissue to analyze glycogen content. The 30 days treatment with various extracts (75 mg/kg body wt) significantly lowered protein thiol levels, which probably represents increased utilization for neutralizing free radicals. There was no significant increase in the levels of renal parameters in the extract treated groups which revealed that the employed dose of the extract is nontoxic to the kidney. There was also a significant decrease in the glycogen content in insulin and alcohol-extract treated groups and should be encouraging for the treatment of diabetes mellitus. The extract showed a promising antioxidant effect, as well as hypoglycemic activity, and should be encouraged for the treatment of diabetes.

    Three phenolic glycosides isolated from the heartwood of Pterocarpus marsupium showed significant free radical and superoxide ion scavenging activity and antioxidant potential that were comparable to, or several folds higher than those of standard antioxidants, trolox and ascorbic acid. The effective concentrations of these compounds were far below their cytotoxic levels. Compound 3, which was characterized to be α-dihydroxychalcone-glycoside (α-DHC), was the most potent one. Subsequent studies demonstrated that α-DHC effectively reduced nitric oxide and cytokine production by the LPS stimulated RAW 264.7 mouse macrophage cell line. The compound effectively attenuated the expression of inflammation-mediating enzymes COX-2 and iNOS at the mRNA as well as protein levels in a concentration dependent manner. It prevented phosphorylation of all the three MAPKs (JNK, ERK, p38) and eventually blocked the activation of downstream elements contributing to inflammation. Phosphorylation of IκB-α and subsequent translocation of NF-κB into the nucleus were restricted, while the expression of stress responsive gene HO-1 was up-regulated. α-DHC targeted Keap-1 by modifying its cysteine thiols, dissociating it from Nrf-2 and facilitating nuclear entry of the latter; and this in turn induced HO-1 expression. Thus α-DHC exerts its anti-inflammatory activity in a dual manner: by down regulating MAPKs and restricting nuclear stabilization of NF-κB at one end, and by disrupting Nrf-2–Keap-1 complex on the other. In conclusion, the anti-inflammatory potential together with its high therapeutic index envisages α-DHC as a prospective candidate molecule for the development of therapeutic strategy against inflammatory disorders. - Highlights: • α-DHC isolated from Pterocarpus marsupium has significant antioxidant potential. • α-DHC inhibits NO, IL-6, IL-1β, TNF-α production in LPS-stimulated RAW 264.7 cells. • α-DHC down-regulates of COX-2, iNOS expression in LPS

    Pterocarpus santalinus is described in the Ayurveda for its wide spectrum of medicinal properties including wound healing. Previously the authors reported animal studies that demonstrated that an ointment made from the bark of this tree was effective without any toxic effects. They used the same ointment in 6 cases of lower extremity wounds. Healing was observed in all wounds. The study was not controlled, the findings are presented here as case studies. Further studies are planned to develop a wound healing ointment from a locally available and inexpensive plant.

Phosphorylation of IκB-α and subsequent translocation of NF-κB into the nucleus were restricted, while the expression of stress responsive gene HO-1 was up-regulated. α-DHC targeted Keap-1 by modifying its cysteine thiols, dissociating it from Nrf-2 and facilitating nuclear entry of the latter; and this in turn induced HO-1 expression. Thus α-DHC exerts its anti-inflammatory activity in a dual manner: by down regulating MAPKs and restricting nuclear stabilization of NF-κB at one end, and by disrupting Nrf-2-Keap-1 complex on the other. In conclusion, the anti-inflammatory potential together with its high therapeutic index envisages α-DHC as a prospective candidate molecule for the development of therapeutic strategy against inflammatory disorders.

    Quorum sensing mechanism allows the microorganisms to resist the antibiotic treatment by forming biofilms. Quorum quenching is one of the mechanisms to control the development of drug resistance in microbes. Endophyte bacteria are beneficial to plant growth as they support the immune system against the pathogen attack. The endophytic bacteria present in Pterocarpus santalinus were screened for the presence of N-acyl homoserine lactones (AHLs) degrading bacteria using biosensor strains and further confirmed by quantifying the violacein production. Cell-free lysate of endophytic bacteria, Bacillus firmus PT18 and Enterobacter asburiae PT39 exhibited potent AHL degrading ability by inhibiting about 80% violacein production in biosensor strain. Furthermore, when the cell-free lysate was applied to Pseudomonas aeruginosa PAO1 and PAO1-JP2 biofilm it resulted in significant (p<0.01) inhibition of biofilm formation. The biofilm inhibition was confirmed by visualization of biofilm slides under fluorescence microscopy, which showed decrease in total biomass formation in treated slides. Isolation and amplification of the gene (aiiA) indicated that the presence of AHL lactonase in cell-free lysate and sequence alignment indicated that AiiA contains a "HXHXDH" zinc-binding motif that is being conserved in several groups of metallohydrolases. Therefore, the study shows the potential of AHLs degradation by AHL lactonase present in cell-free lysate of isolated endophytic bacteria and inhibition of quorum sensing regulated biofilm formation in P. aeruginosa PAO1.

    2015-01-01

    Pterocarpus indicus Willd is a tropical woody legume that holds promise for plantation forestry. Two glasshouse experiments were undertaken on two soil types to determine the phosphorus (P) concentration ranges in the foliage of P-stressed and healthy plants, and to define cri-tical P concentrations for the diagnosis of deficiency and toxicity. There was a narrow range in rates of P fertilizer, supplied as Ca(H2PO4)2?H20, between deficiency and toxicity compared to other tree species. The relationship between shoot yield and P concentration in the youngest fully expanded leaf enabled critical P concentrations for the diagnosis of deficiency (0.17%) and toxicity (0.41%) to be determined at 90% maximum yield from linear re-gressions fitted to the data. The foliar P concentration ranges for deficiency and toxicity were similar to other nitrogen-fixing trees. The defined P concentration ranges and the critical P concentrations for the diagnosis of P deficiency and P toxicity should be useful for monitoring the P status of nursery stock and the health of young seedlings after out-planting.

    Recently there has been increasing interest in plants and plant-derived compounds as raw food and medicinal agents. In Ayurveda, an Indian system of traditional medicine, a wide spectrum of medicinal properties of Pterocarpus santalinus is described. Many important bioactive phytocompounds have been extracted and identified from the heartwood of P. santalinus. Bioactive compounds typically occur in small amounts and have more subtle effects than nutrients. These bioactive compounds influence cellular activities that modify the risk of disease rather than prevent deficiency diseases. A wide array of biological activities and potential health benefits of P. santalinus have been reported, including antioxidative, antidiabetic, antimicrobial, anticancer, and anti-inflammatory properties, and protective effects on the liver, gastric mucosa, and nervous system. All these protective effects were attributed to bioactive compounds present in P. santalinus. The major bioactive compounds present in the heartwood of P. santalinus are santalin A and B, savinin, calocedrin, pterolinus K and L, and pterostilbenes. The bioactive compounds have potentially important health benefits: These compounds can act as antioxidants, enzyme inhibitors and inducers, inhibitors of receptor activities, and inducers and inhibitors of gene expression, among other actions. The present review aims to understand the pharmacological effects of P. santalinus on health and disease with "up-to-date" discussion.

    The Man/Glc-specific legume lectin from the seeds of the African bloodwood tree (Pterocarpus angolensis) was crystallized in the presence of the disaccharide ligand Man(alpha1-3)ManMe. Small crystals initially appeared from a preliminary screen, but proved difficult to reproduce. The initial crystals were used to prepare microseeds, leading to a reproducible crystallization protocol. All attempts to obtain crystals directly of the ligand-free protein or of other carbohydrate complexes failed. However, the Man(alpha1-3)ManMe co-crystals withstand soaking with ten other carbohydrates known to bind to the lectin. Soaking for 15 min in 100 mM carbohydrate typically resulted in complete replacement of Man(alpha1-3)ManMe by the desired carbohydrate despite the involvement of lattice contacts at the binding site. Transferring the crystals for two weeks in carbohydrate-free artificial mother liquor resulted in the complete removal of the sugar from one of the two monomers in the asymmetric unit. Additional treatment of these crystals with 100 mM EDTA for two weeks resulted in removal of the structural calcium and manganese ions, which is accompanied by significant structural rearrangements of the loops that constitute the carbohydrate-binding site.

    There have been several recent reports of Pterocarpus angolensis (kiaat) trees dying in South Africa, Zambia and Zimbabwe, where this tree is used in traditional medicine and is a valuable source of timber for woodcarving and furniture. A survey of material from diseased P. angolensis trees in South Africa yielded isolates of the Botryosphaeriaceae, an important fungal family known to cause a number of tree diseases. The aim of this study was to identify these Botryosphaeriaceae and to determine their pathogenicity to P. angolensis with branch inoculations. Seven species of the Botryosphaeriaceae were identified based on a combination of morphological characteristics and sequences from the ITS and EF-1α gene regions. Four of these represent undescribed taxa for which the names Pseudofusicoccum violaceum, P. olivaceum, Diplodia alatafructa and Fusicoccum atrovirens are provided. The remaining three species collected include Lasiodiplodia theobromae, L. pseudotheobromae and L. crassispora. Inoculation trials on tree branches showed that L. pseudotheobromae and one isolate of D. alatafructa differed significantly from control inoculations. The high levels of virulence and common occurrence of L. pseudotheobromae suggest that this species could play a role in tree dieback and death.

    Accumulation of β-amyloid peptides (Aβ) and its progressive deposition into amyloid plaques are key events in the aetiology of Alzheimer's disease (AD). To date, AD treatment is symptomatic and consists of drugs treating the cognitive decline. Identifying molecules specifically targeting Aβ production or aggregation represents a huge challenge in the development of specific AD treatments. Several molecules reported as γ-secretase inhibitors or modulators have been evaluated, but so far none of them have proven to be selective or fully efficient. We have previously investigated the potential interest of plant extracts and we reported that Pterocarpus erinaceus stem-bark extract was active on Aβ release. Our aim here was to characterize the mechanisms by which this extract reduces Aβ levels. We tested P. erinaceus extract at non-toxic concentrations on cells expressing the human amyloid precursor protein (APP695) or its amyloidogenic β-cleaved C-terminal fragment (C99), as well as on neuronal cell lines. P. erinaceus extract was found to inhibit Aβ release. We further showed that this extract inhibited γ-secretase activity in cell-free and in vitro assays, strongly suggesting that P. erinaceus extract is a natural γ-secretase inhibitor. Importantly, this extract did not inhibit γ-secretase-dependent Notch intracellular domain release. P. erinaceus extract appears as a new potent γ-secretase inhibitor selective towards APP processing. 2013 S. Karger AG, Basel

    The aqueous decoction of Pterocarpus erinaceus has been traditionally used in Benin against memory troubles. New strategies are needed against Alzheimer׳s disease (AD), for, to date, AD treatment is symptomatic and consists in drugs treating the cognitive decline. An interesting target is the β-amyloid peptide (Aβ), whose accumulation and progressive deposition into amyloid plaques are key events in AD aetiology. Identifying new and more selective γ-secretase inhibitors or modulators (none of the existing has proven so far to be selective or fully efficient) appears in this respect of particular interest. We studied the activity and mechanisms of action of Pterocarpus erinaceus kino aqueous extract, after the removal of catechic tannins (KAST). We tested KAST at non-toxic concentrations on cells expressing the human Amyloid Precursor Protein (APP695), as well as on primary neurons. Pterocarpus erinaceus extract was found to inhibit Aβ release in both models. We further showed that KAST inhibited γ-secretase activity in cell-free and in vitro assays, strongly suggesting that KAST is a natural γ-secretase inhibitor. Importantly, this extract did not inhibit the cleavage of Notch, another γ-secretase substrate responsible for major detrimental side effects observed with γ-secretase inhibitors. Epicatechin was further identified in KAST by HPLC-MS. Pterocarpus erinaceus kino extract appears therefore as a new γ-secretase inhibitor selective towards APP processing.

    Pterocarpus erinaceus Poir. belonging to Fabacae familly is used as medicinal plant in Burkina Faso's folk medicine. Roots of P. erinaceus are used to treat ulcer, stomach ache and inflammatory diseases. The objective of the present study was to carry out phytochemical composition of methanol (MeOH) and dichloromethane (DCM) extracts from Pterocarpus erinaceus roots, to isolate pure compounds, and to evaluate their pharmacological activities. Chromatographic fractionation led to the isolation of active components of the extracts. The structures were established by NMR analysis and comparison with data from literature. The anti-inflammatory activity was evaluated using croton oil-induced edema of mice ear as well as the effect of extracts against lipoxygenase and lipid peroxidation was evaluated. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Cupric-reducing antioxidant capacity (CUPRAC) methods were used to evaluate the antioxidant activity of the extracts. Friedelin (1), 3a-hydroxyfriedelan-2-one (2), a-sophoradiol (3) and stigmasterol (4) were isolated from DCM extract and maltol-6-O-apiofuranoside-glucopyranoside (5) isolated from MeOH. DCM extract and friedelin, 3a-hydroxyfriedelan-2-one, a-sophoradiol showed a significant anti-inflammatory effect against ear edema. Friedelin (1), α-sophoradiol (3) and maltol-6-O-apiofuranoside-glucopyranoside (5) exhibited lipoxygenase inhibition. MeOH extract (100 μg/mL) inhibited lipoxygenase and lipid peroxidation activities at 45.1 ± 3% and 30.7 ± 0.5% respectively. MeOH extract, ethyl acetate fraction and butanol fraction exhibited antioxidant property with both two methods used. The results suggested that the extracts and compounds from roots of Pterocarpus erinaceus possessed local anti-inflammatory effect, antioxidant properties and inhibitor effect against lipoxygenase and lipid peroxidation activities.

    To investigate the restorative effect of Pterocarpus erinaceus (P. erinaceus) and homopterocarpin, an isoflavonoid isolated from it, on indomethacin-induced disruption in gastric homeostasis in rats. Adult rats were divided into five groups and fasted for 48 h before treatment. Group 1 received olive oil (vehicle), group 2 received 25 mg/kg indomethacin while groups 3-5 received cimetidine (100 mg/kg), homopterocarpin (25 mg/kg) and P. erinaceus ethanolic stem bark extract (100 mg/kg) respectively. After 1 h, all the groups except group 2 were administered 25 mg/kg of indomethacin. One hour later, the rats were sacrificed and the ulcer index and other gastroprotective indices were evaluated. Indomethacin caused significant injury to the stomach of the rats as reflected in the ulcer indices (9.0±1.4) as compared with that of control (2.0±0.0). Equally, there were significant increases in gastric acid concentration and malondialdehyde level in the stomachs of the ulcerated animals compared with the control. However mucus content, reduced gluthatione level and gastric pH were significantly reduced in the ulcerated animals compared with the control. Pretreatment with either Pterocarpus bark extract or homopterocarpin reversed the effects of indomethacin on the evaluated parameters. These results indicate that both homopterocarpin and Pterocarpus extract offered gastroprotection against indomethacin-induced ulcer by antioxidative mechanism and the modulation of gastric homeostasis. The results also suggest that homopterocarpin might be responsible for, or contribute to the antiulcerogenic property of P. erinaceus. Copyright © 2013 Hainan Medical College.

    Tidal freshwater forested wetlands occupy a narrow ecological space determined by the balance between saltwater and freshwater inputs to the system. However, this balance is not well understood. In the Caribbean, tidal freshwater-forested wetlands dominated by Pterocarpus officinalis are vulnerable to changes in tidal influence and freshwater inputs. In this setting, the seasonal interactions of saltwater and freshwater inputs create less than ideal conditions for these forests to survive. Hence, it is crucial to have a better understanding of the hydrologic context of these and other tidal freshwater forested wetlands. We examined the extent of tidal forcing and saltwater influence in the largest Pterocarpus swamp of Puerto Rico by installing automated water level and conductivity recorders across a tidal creek transect at four different distances from the ocean, and by using water stable isotopes ratios (δD, δ18O) as natural tracers to determine the most important freshwater sources for tree transpiration. Records of water level and salinity revealed that the amount of rainfall was most influential on saltwater wedge migration in the creek for locations at the front and back of the tidal network, but that tidal dynamics were most influential at the middle section of the tidal network. Saltwater intrusion into the deepest parts of the tidal network was most prominent during sustained dry periods. Isotopic ratios of the surface water samples in the forest revealed that most of the water there was derived from freshwater runoff, but there was a seasonal change in its relative contribution to the forest hydrology. During the dry season, high δ values suggested the presence of runoff-derived water that had undergone evaporation, and saline influences were found in locations where past deforestation created preferential pathways for this water. During both seasons, δ 18O values of groundwater revealed the influence of saline water at depths 60 cm and greater near

    Pterocarpus angolensis grows throughout northern Botswana and may be found in all woodland types as well as in evergreen and deciduous forests. It is among the few indigenous trees that thrive in the deep Kalahari sands. P. angolensis produces a hard wood timber of attractive appearance. Due to its flexibility, resistance and lightweight, the communities in Botswana use the species for making door frames, window frames, canoes, canoe peddles, spear handles for use in game hunting, fishing and general construction. The community also use it as a carving and sculpting medium. Traditionally, all parts of the tree are used for medicinal purposes.

    The phenolic fraction and the crude extract from Tribulus pterocarpus have different biological activity, including antiplatelet-antiadhesive properties. Since it is demonstrated that hyperhomocysteinemia may act as stimulator of blood platelet activation (platelet adhesion, aggregation, and secretion), but various antiplatelet compounds are able to reduce hyperactivation of blood platelets induced by hyperhomocysteinemia. The aim of our present experiments was to investigate in vitro one of the step in platelet activation process - platelet adhesion to collagen induced by the model of severe hyperhomocyateinemia in the presence of the phenolic fraction and the crude extract from T. pterocarpus. Severe hyperhomocysteinemia was induced by reduced form of Hcy in the concentrations 0.1mM and 1mM, or using HTL in the concentrations 0.1, 0.5 and 1 μM. Adhesion of blood platelets to collagen was determined according to Tuszynski and Murphy. We observed that the phenolic fraction and the crude extract from T. pterocarpus have the inhibitory effect on platelet adhesion during severe hyperhomocysteinemia. The action of tested phenolic and crude extract was concentration-dependent, but the phenolic fraction was stronger antiadhesive action than the crude extract. We suggest that T. pterocarpus may be good source of antiplatelet compounds during hyperhomocysteinemia. Copyright © 2013. Published by Elsevier Ltd.

    A total of fifty root nodules isolates of fast-growing and slow growing rhizobia from Pterocarpus ennaceus and Pterocarpus lucens respectively native of sudanean and sahelian regions of Senegal were characterized. These isolates were compared to representative strains of known rhizobial species. Twenty-two new isolates were slow growers and twenty-eight were fast growers. A polyphasic approach was performed including comparative total protein sodium dodecyl sulphate polyacrylamide gel (SDS-PAGE) profile analysis; 16S rDNA and 16S-23S rDNA intergenic spacer (IGS) sequence analysis. By SDS-PAGE the slow growing isolates grouped in one major cluster containing reference strains of Bradyrhizobium sp. including strains isolated in Africa, in Brazil and in New Zealand. Most of the fast-growing rhizobia grouped in four different clusters or were separate strains related to Rhizobium and Mesorhizobium strains. The 16S rDNA and 16S-23S rDNA IGS sequences analysis showed accurately the differentiation of fast growing rhizobia among the Rhizobium and Mesorbizobium genospecies. The representative strains of slow growing rhizobia were identified as closely related to Bradyrbizobium elkanii and Bradyrhizobium japonicum. Based on 16S rDNA sequence analysis, one slow growing strain (ORS199) was phylogenetically related to Bradyrbizobium sp. (Lupinus) and Blastobacter denitrificans. This position of ORS 199 was not confirmed by IGS sequence divergence. We found no clear relation between the diversity of strains, the host plants and the ecogeographical origins.

    The crystal structure of the Man/Glc-specific seed lectin from Pterocarpus angolensis was determined in complex with methyl-alpha-d-glucose, sucrose, and turanose. The carbohydrate binding site contains a classic Man/Glc type specificity loop. Its metal binding loop on the other hand is of the long type, different from what is observed in other Man/Glc-specific legume lectins. Glucose binding in the primary binding site is reminiscent of the glucose complexes of concanavalin A and lentil lectin. Sucrose is found to be bound in a conformation similar as seen in the binding site of lentil lectin. A direct hydrogen bond between Ser-137(OG) to Fru(O2) in Pterocarpus angolensis lectin replaces a water-mediated interaction in the equivalent complex of lentil lectin. In the turanose complex, the binding site of the first molecule in the asymmetric unit contains the alphaGlc1-3betaFruf form of furanose while the second molecule contains the alphaGlc1-3betaFrup form in its binding site.

    2007-02-01

    The anti-H. pylori activity of Pterocarpus santalinus (PS), a traditional herb, has been assessed and compared with that of bismuth subcitrate, through in vitro studies employing rat gastric epithelial cell cultures and H. pylori isolates from gastric mucosal biopsy patients. The MIC of PS was found to be 20 microg/mL. H. pylori was co-cultivated with rat gastric epithelial cells in the presence/absence of PS at its MIC. A reduction in the activity of urease, a normal appearance of the epithelial cells on electron microscopic examination, a decrease in lipid peroxidation and lactate dehydrogenase suggests the possible anti-H. pylori activity of PS.

    Objective:To screen methanol and dichloromethane extracts of stem bark of Pterocarpus erinaceus for anti-inflammatory, analgesic, in vitro antioxidant activities and phytochemical analysis. Methods:Anti-inflammatory activity was determined by using carrageenan induced-edema of mice paw and croton oil-induced edema of mice ear;analgesic effect was evaluated using acetic acid-induced writhing. Phytochemical screening of extracts was performed by thin layer chromatography. The chromatographic fractionation led to the isolation of main active components as friedelin, lupeol and epicathechin. The structures were established by TLC and nuclear magnetic resonance studies. Results:Both methanol and dichloromethane extracts, friedelin, lupeol and epicatechin showed a significant anti-inflammatory effect using croton oil induced-ear edema. Furthermore, the action of dichloromethane extract was more important. At the doses of 100 and 200 mg/kg, the methanol extract was able to reduce the carrageenan induced-hind paw edema, while at the doses of 100, 200 and 400 mg/kg, it showed an important analgesic effect against writhing induced by acetic acid injection of 38.8%, 68.0%and 74.3%, respectively. Antioxidative properties of methanol extract and its dichloromethane and ethyl acetate fractions were assessed by using the 1,1-diphenyl-2-picrylhydrazyl method. The methanol extract showed the stronger radical scavenging activity than dichloromethane and ethyl acetate fractions, with an antiradical power of 5, 3.5 and 2 respectively. The main components isolated from these extracts as friedelin, lupeol and epicathechin were responsible of these activities. Conclusions:The results suggest that the stem bark extracts of Pterocarpus erinaceus possessed important anti-inflammatory, analgesic activities and strong antioxidant properties, therefore, they could be used as natural potential ingredients for pharma ceutical industry.

Antioxidative properties of methanol extract and its dichloromethane and ethyl acetate fractions were assessed by using the 1,1-diphenyl-2-picrylhydrazyl method. The methanol extract showed the stronger radical scavenging activity than dichloromethane and ethyl acetate fractions, with an antiradical power of 5, 3.5 and 2 respectively. The main components isolated from these extracts as friedelin, lupeol and epicathechin were responsible of these activities. The results suggest that the stem bark extracts of Pterocarpus erinaceus possessed important anti-inflammatory, analgesic activities and strong antioxidant properties, therefore, they could be used as potential natural ingredients in the pharmaceutical industry.

    Narra (Pterocarpus indicus) wood chips were irradiated with positive hydrogen ions H{sup +} and H{sub 2}{sup +} to make them hydrophobic. The ions were produced and extracted from a gas discharge ion source. The extracted beam current ranges from 0.01 to 0.07{mu}A for discharge currents of 1.0-4.0mA, discharge potential between 600V and 1000V. The chips, positioned at 70mm downstream from the ion source, were processed for different time periods and discharge currents. The wettability was characterized by the contact angle of the liquid droplet with respect to the wood surface. Surface modifications were assessed with by measurements of the water contact angle. Tests indicate retarded absorption characteristics for ion-irradiated samples compared to controlled samples. The longest absorptive inhibition were exhibited by samples irradiated for 30min, at discharge current of 1.0mA, 720eV ion energy and 0V extraction potential. Scanning electron micrographs reveal the difference in morphologies of treated and untreated samples. The results prove that low energy beams of hydrogen from a gas discharge ion source are suitable in transforming surfaces of wood chips to be water resistant.

    The insect antifeedant activities of pterocarpans and a sesquiterpene alcohol from the dichloromethane extract of Pterocarpus macrocarpus Kruz. (Leguminosae) were evaluated against the common cutworm, Spodoptera litura F. (Noctuidae), and the subterranean termite, Reticulitermes speratus (Kolbe)(Rhinotermitidae). Three pterocarpans, (-)-homopterocarpin (1), (-)-pterocarpin (2), and (-)-hydroxyhomopterocarpin (3) and the sesquiterpene alcohol, (+)-pterocarpol (5), were isolated from the dichloromethane extract of the heartwood of P. macrocarpus under guidance by a biological assay. Among these natural products, the most active insect antifeedant against both S. litura and R. speratus was 1. On the other hand, sesquiterpene alcohol 5 showed less insect antifeedant activity than the other pterocarpans against both insect species. While its methylated derivative, (-)-methoxyhomopterocarpin (4), showed high biological activity, 3 showed less insect antifeedant activity in this study. Interestingly, racemic 1 did not show insect antifeedant activity against S. litura. However, all of the test pterocarpans and isoflavones showed antifeedant activity against the test termites. Additionally, since these compounds were major constituents of P. macrocarpus, these antifeedant phenolics may act as chemical defense factors in this tree. In Thailand, lumber made from this tree is used to make furniture and in building construction due to its resistance to termite attack.

    The crystal structure of Pterocarpus angolensis lectin is determined in its ligand-free state, in complex with the fucosylated biantennary complex type decasaccharide NA2F, and in complex with a series of smaller oligosaccharide constituents of NA2F. These results together with thermodynamic binding data indicate that the complete oligosaccharide binding site of the lectin consists of five subsites allowing the specific recognition of the pentasaccharide GlcNAc beta(1-2)Man alpha(1-3)[GlcNAc beta(1-2)Man alpha(1-6)]Man. The mannose on the 1-6 arm occupies the monosaccharide binding site while the GlcNAc residue on this arm occupies a subsite that is almost identical to that of concanavalin A (con A). The core mannose and the GlcNAc beta(1-2)Man moiety on the 1-3 arm on the other hand occupy a series of subsites distinct from those of con A.

    This study investigates the in vitro antioxidant potentials and attenuation of acetaminophen-induced redox imbalance by Pterocarpus osun Craib (Fabaceae) leaf in Wistar rat liver. The in vitro antioxidant activity of the extract (0.2-1.0 mg/mL) was evaluated using 2,2-diphenyl-1-picrylhydrazl (DPPH), hydrogen peroxide, superoxide ion, 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate (ABTS), and ferric ion. The extract (150 and 300 mg/kg body weight) significantly (P<0.05) attenuated the altered liver and serum enzymes of acetaminophen treated animals. Superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glucose-6-phosphate dehydrogenase activities as well as vitamins C and E, and glutathione levels were significantly (P<0.05) elevated by the extract. The activities of uridyl diphosphoglucuronosyl transferase (59%), quinone oxidoreductase (53%), and glutathione S-transferase (73%) significantly increased. The extract of P. osun leaf extract at 1.0mg/mL scavenged the DPPH, hydrogen peroxide, superoxide ion, and ABTS at 94, 98, 92, and 86%, respectively, while ferric ion was significantly reduced. There was attenuation of malondialdehyde and lipid hydroperoxide. The results indicates that P. osun leaves attenuated acetaminophen-induced redox imbalance, possibly acting as free radical scavenger, inducer of antioxidant and drug-detoxifying enzymes, which prevented/reduced lipid peroxidation.

    The crystal structure of a Man/Glc-specific lectin from the seeds of the bloodwood tree (Pterocarpus angolensis), a leguminous plant from central Africa, has been determined in complex with mannose and five manno-oligosaccharides. The lectin contains a classical mannose-specificity loop, but its metal-binding loop resembles that of lectins of unrelated specificity from Ulex europaeus and Maackia amurensis. As a consequence, the interactions with mannose in the primary binding site are conserved, but details of carbohydrate-binding outside the primary binding site differ from those seen in the equivalent carbohydrate complexes of concanavalin A. These observations explain the differences in their respective fine specificity profiles for oligomannoses. While Man(alpha1-3)Man and Man(alpha1-3)[Man(alpha1-6)]Man bind to PAL in low-energy conformations identical with that of ConA, Man(alpha1-6)Man is required to adopt a different conformation. Man(alpha1-2)Man can bind only in a single binding mode, in sharp contrast to ConA, which creates a higher affinity for this disaccharide by allowing two binding modes.

    2005-11-01

    The ethanol extract of Pterocarpus santalinus (PS) was evaluated for gastroprotection in rats using ibuprofen as the induction model. Rats treated with PS (100-400 mg/kg) showed a significant reduction in gastric lesions. PS at a dose of 200 mg/kg was found to be the minimum effective dose and hence further studies with that dose were carried out. PS treatment increased the LDH activity and decreased the lipid peroxidation levels. The extract had the ability to increase the antioxidant enzymes SOD, CAT and GPx when compared with the untreated but induced rats. The membrane bound ATPases - H(+)K(+)ATPase, Na(+)K(+)ATPase and Ca(2+)ATPases were increased upon the induction with ulcerogen. The treated group showed a decrease in the activities of these enzymes and also had the ability to restore the sodium and potassium ion concentrations to near normal levels, which were altered by ibuprofen mediated acid stimulation. The results suggest that the antiulcer properties of PS could traced to its acid inhibiting potential, antioxidant activity and the ability to maintain functional integrity of the cell membranes.

    Full Text Available Pterocarpus santalinus (Family – Fabaceae popularly known as Red Sanders is an endemic species confined to Southern parts of Eastern Ghats of India specially in Andhra Pradesh. Heartwood of Red Sanders has high demand in domestic as well as international market and the wavy grained wood is valued.  Along with its extensive use in furniture, the red dye obtained from the wood is used as colouring agent for textile, medicine and food. The heartwood can accumulate various elements and rare earth elements like strontium cadmium, zinc, copper and uranium. The wood has different uses in traditional and folklore medicines and is used for the treatment of diabetes, prickly heat, skin diseases and for various other ailments. A number of studies have been carried out to anatomically and phenotypicaly screen wavy grain at seedling stage. Morphological variability and genetic diversity studies reveal that Red Sanders harbours enormous variability. Though, macro and micro propagation protocol have been developed, further refinement is required for mass propagation. Andhra Pradesh Forest Department has also initiated different activities under tree improvement programme. Considering the wood demand, restricted distribution, slow regeneration, illegal harvest, trade and habitat destruction, the species has been categorized as endangered by International Union for Conservation of Nature and has been listed in Convention on International Trade in Endangered Species of Wild Fauna and Flora and is also classified as a “reserved tree” under the Andhra Pradesh Preservation of Private Forest Rules, 1978. To revive the past glory of this valuable species, Government agencies, farmers, entrepreneurs and policy makers have to join hands for its protection, sustainable utilization and conservation.

    From 1 kg of defatted Pterocarpus angolensis (mukwa tree) seed meal, 21.6 grams of an alpha,D-mannose/glucose-specific lectin can be purified on mannose-Sepharose. Relative affinities for several (oligo)saccharides and glycoproteins were studied by haemagglutination-inhibition. Gel filtration shows that the lectin exists as a dimer above pH 5 and as a monomer below pH 3.5. This is confirmed by studies on the release of lectin subunits that were adsorbed from solution to lectin monomers immobilized onto Eupergit-c. From the gel filtration patterns it is calculated that a residue with pK(a) of about 4.4 is involved in dimer dissociation. Titration of glutamic acids (E60, E209) is postulated to be involved. CD spectroscopy shows that the secondary structure of the lectin is unchanged between pH 1 and 12.5, and that the tertiary structure remains unchanged between pH 5 and 12. In the acid pH region, reversible spectral changes occur that may be due to the titration of one or more amino acids with a pK(a) value of 3.9-4.2, probably aspartic acid. These residues are implicated in sugar-binding but not in dimerization of the lectin. Only at pH 12.5, irreversible denaturation occurs. Mukwa lectin displays full carbohydrate-binding capacity between pH 4 and 12, as is concluded from ELLA (Enzyme Linked Lectin Assay) using ovalbumin and fetuin, and from binding of the same glycoproteins to immobilized lectin monomers. The lectin is rapidly and fully reversibly demetallized at pH 2.5 with 5 mM EDTA. The demetallized lectin is completely devoid of sugar-binding activity. Mukwa lectin is a very thermostable molecule (at least till 85 degrees C). However, addition of non-ionic detergents substantially lowers its thermostability.

    Pterocarpus santalinus, a traditional medicinal plant has shown protective mechanisms against various complications. The aim of the present study is to evaluate therapeutic efficacy of P. santalinus heartwood methanolic extract (PSE) against alcohol-induced oxidative/nitrosative stress leading to hepatotoxicity. In-vitro studies revealed that PSE possess strong DPPH (1,1-diphenyl-2-picryl hydrazyl) and nitric oxide radical scavenging activity. For in vivo studies male albino Wistar rats were treated with 20% alcohol (5g/kg b.wt/day) and PSE (250mg/kg b.wt/day) for 60days. Results showed that alcohol administration significantly altered plasma lipid profile with marked increase in the levels of plasma transaminases (ALT and AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and gamma glutamyl transferase (γGT). Moreover, lipid peroxides, nitric oxide (NOx) levels in plasma and liver were increased with increased iNOS protein expression in liver was noticed in alcohol administered rats and these levels were significantly brought back close to normal level by PSE administration except iNOS protein expression. Alcohol administration also decreased the content of reduced glutathione (GSH) and activities of glutathione peroxidase (GPx), glutathione-s transferase (GST), glutathione reductase (GR), superoxide dismutase (SOD) and catalase (CAT) in liver, which were significantly enhanced by administration of PSE. The active compounds pterostilbene, lignan and lupeols present in PSE might have shown protection against alcohol-induced hepatic damage by possibly reducing the rate of lipid peroxidation, NOx levels and increasing the antioxidant defence mechanism in alcohol administered rats. Both biochemical and histopathological results in the alcohol-induced liver damage model emphasize beneficial action of PSE as a hepatoprotective agent. Copyright © 2016 Elsevier Masson SAS.

    Pterocarpus officinalis (Jacq.) seedlings inoculated with the arbuscular mycorrhizal fungus, Glomus intraradices, and the strain of Bradyrhizobium sp. (UAG 11A) were grown under stem-flooded or nonflooded conditions for 13 weeks after 4 weeks of nonflooded pretreatment under greenhouse conditions. Flooding of P. officinalis seedlings induced several morphological and physiological adaptive mechanisms, including formation of hypertrophied lenticels and aerenchyma tissue and production of adventitious roots on submerged portions of the stem. Flooding also resulted in an increase in collar diameter and leaf, stem, root, and total dry weights, regardless of inoculation. Under flooding, arbuscular mycorrhizas were well developed on root systems and adventitious roots compared with inoculated root systems under nonflooding condition. Arbuscular mycorrhizas made noteworthy contributions to the flood tolerance of P. officinalis seedlings by improving plant growth and P acquisition in leaves. We report in this study the novel occurrence of nodules connected vascularly to the stem and nodule and arbuscular mycorrhizas on adventitious roots of P. officinalis seedlings. Root nodules appeared more efficient fixing N(2) than stem nodules were. Beneficial effect of nodulation in terms of total dry weight and N acquisition in leaves was particularly noted in seedlings growing under flooding conditions. There was no additive effect of arbuscular mycorrhizas and nodulation on plant growth and nutrition in either flooding treatment. The results suggest that the development of adventitious roots, aerenchyma tissue, and hypertrophied lenticels may play a major role in flooded tolerance of P. officinalis symbiosis by increasing oxygen diffusion to the submerged part of the stem and root zone, and therefore contribute to plant growth and nutrition.

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

    Since Pterocarpus santalinus and Dalbergia louvelii, which are of precious Rosewood, are very similar in their appearance and anatomy characteristics, cheaper Hongmu D. louvelii is often illegally used to impersonate valuable P. santalinus, especially in Chinese furniture manufacture. In order to develop a rapid and effective method for easy confused wood furniture differentiation, we applied tri-step identification method, i.e., conventional infrared spectroscopy (FT-IR), second derivative infrared (SD-IR) spectroscopy and two-dimensional correlation infrared (2DCOS-IR) spectroscopy to investigate P. santalinus and D. louvelii furniture. According to FT-IR and SD-IR spectra, it has been found two unconditional stable difference at 848 cm-1 and 700 cm-1 and relative stable differences at 1735 cm-1, 1623 cm-1, 1614 cm-1, 1602 cm-1, 1509 cm-1, 1456 cm-1, 1200 cm-1, 1158 cm-1, 1055 cm-1, 1034 cm-1 and 895 cm-1 between D. louvelii and P. santalinus IR spectra. The stable discrepancy indicates that the category of extractives is different between the two species. Besides, the relative stable differences imply that the content of holocellulose in P. santalinus is more than that of D. louvelii, whereas the quantity of extractives in D. louvelii is higher. Furthermore, evident differences have been observed in their 2DCOS-IR spectra of 1550-1415 cm-1 and 1325-1030 cm-1. P. santalinus has two strong auto-peaks at 1459 cm-1 and 1467 cm-1, three mid-strong auto-peaks at 1518 cm-1, 1089 cm-1 and 1100 cm-1 and five weak auto-peaks at 1432 cm-1, 1437 cm-1, 1046 cm-1, 1056 cm-1 and 1307 cm-1 while D. louvelii has four strong auto-peaks at 1465 cm-1, 1523 cm-1, 1084 cm-1 and 1100 cm-1, four mid-strong auto-peaks at 1430 cm-1, 1499 cm-1, 1505 cm-1 and 1056 cm-1 and two auto-peaks at 1540 cm-1 and 1284 cm-1. This study has proved that FT-IR integrated with 2DCOS-IR could be applicable for precious wood furniture authentication in a direct, rapid and holistic manner.

    2012-12-01

    Our study was designed to identify the relationships between climate parameters, such as precipitation, and δ18O values of tree ring α-cellulose extracted from exactly dated tree rings of Pterocarpus angolensis trees growing in the arid to semiarid Mzola region of western Zimbabwe. This species is known to be sensitive to variation in rainfall. In this region, the wet season occurs during the austral summer from mid November to early April followed by a dry winter season from around June through October. Overall, the total annual rainfall exhibits a high degree of spatial and temporal variation with a mean of less than 600 mm per year. We applied the Modified Brendel technique to isolate α-cellulose from raw wood samples extracted from two P. angolensis trees and measured the δ18O values using continuous flow isotope ratio mass spectrometry. We developed a 30-year (1955-1984) δ18O chronology and correlated it with tree-ring width, meteoric water δ18O values, monthly and seasonal precipitation totals, and mean monthly temperature. The δ18O values of meteoric water for this region were obtained from the Global Network of Isotopes in Precipitation (GNIP) and correlated with the δ18O values of tree ring α-cellulose. We identified a positive correlation (p=.03) between the δ18O in tree ring α-cellulose and the δ18O values of meteoric water. The δ18O values are significantly negatively correlated (p=0.01) with precipitation during November through February. This trend is consistent with depleted δ18O values measured in summer precipitation during periods of high rainfall, most likely the result of the isotopic amount effect reported in tropical regions. We also investigated the possibility of an isotopic temperature effect for δ18O in rainfall, which also may be reflected in the δ18O values in tree ring α-cellulose. The strongest correlations with temperature (positive values) were found in the previous December, June and July, with p-values ranging from

    Full Text Available Introduction: In the recent years, plants containing flavonoids have gained much more interest in research area, as they are found to be specific ligands for benzodiazepine receptors. Material and Methods: In our investigation, we evaluated the neuropharmacological profile of petroleum, chloroform and ethanolic extracts of aerial part of Lippia nodiflora Linn. With experimental models using test such as potentiation of diazepam-induced sleeping time, locomotor activity, motor coordination, exploratory behavior pattern, elevated plus maze and maximal electroshock convulsions. Diazepam at doses of 5, 4, and 1 mg/kg served as standard. Results: Results showed that the ethanolic extract of L. nodifl ora at both doses (250 and 500 mg/kg p.o. and its chloroform extract at a higher dose of 500 mg/kg produced central inhibitory (sedative effects, anticonvulsant effect and anxiolytic effect in mice. Values were statistically significant (P < 0.05 and P < 0.01 when compared to the control group. The petroleum ether extract of plant at both dose levels (250 and 500 mg/kg p.o. did not produce any central effects. Conclusion: In conclusion, we can say that the ethanolic and chloroform extracts showed the central inhibitory activity due to the presence of fl avonoids and this fact was also supported by the finding that the petroleum ether extract did not show any central effect and flavonoids were not found in it.

    Sensitive plant (Mimosa pudica Linn.) fibre is a natural fibre with electrically conductive property. Because of its electro-active sensing nature, it has been found very interesting among physicists, chemists, biologists, material scientists and technologists. So far as our knowledge is concerned; there is no report on the X-ray structure of M. pudica fibre using diffraction technique. In the present report, the M. pudica fibre has been extracted from the stem of the herb by sinking the stem in 10% NaOH solution for one week. The diffraction pattern of the fibre is found out to be cellulose-I. The effect of the fibre structure and its orientation due to different mounting have been investigated using X-ray diffraction technique. The I max of cellulose-I has been observed along (002) and (10overline{1)} for the perpendicular and parallel mounting of the native-fibre, respectively. Full width at half maxima of the diffraction profile turns out to be decreased with fibre orientation. Dimension of crystallite size D hkl estimated in the perpendicular mounting D_{hkl}^{ bot } is more as compared to that of the parallel mounting D_{hkl}^{{^{allel } }} . The smallest crystallite sizes observed in both parallel and perpendicular mounting are 18.78 and 30.78 Å respectively. It is expected that the present study may help to analyse the X-ray diffraction of fibre materials in general and natural fibres in particular.

    Pterocarpus indicus Willd has been widely used as a traditional medicine to treat edema, cancer, and hyperlipidemia, but its antiallergic properties and underlying mechanisms have not yet been studied. The purpose of this study was to evaluate the antiallergic activity of Pterocarpus indicus Willd water extract (PIW) using activated mast cells and an atopic dermatitis (AD)-like mouse model. PIW decreased IgE/Ag-induced mast cell degranulation and the phosphorylation of Syk and downstream signaling molecules such as PLC-γ, Akt, Erk 1/2, JNK compared to stimulated mast cells. In DNCB-induced AD-like mice, PIW reduced IgE level in serum, as well as AD-associated scratching behavior and skin severity score. These results indicate that PIW inhibits the allergic response by reducing mast cell activation and may have clinical potential as an antiallergic agent for disorders such as AD.

    Full Text Available The antibacterial activities of cold and hot ethanol extracts of air-dried leaves of Carica papaya, Pterocarpus soyauxii, and Vernonia amygdalina on clinical isolates of Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus and Bacillus subtilis were investigated. The cup-plate agar method was used to determine bacterial susceptibility. All the plant extracts screened were potent on the entire clinical isolates tested. However, there was no significant difference in the inhibition zone diameters of the plant extracts screened (on all the test isolates. There was also no significant difference in the inhibition zone diameters between the cold and hot ethanol extracts of each plant. Phytochemical analysis revealed the presence of alkaloids, anthroquinone, flavonoids, saponins, steroids, tannins, terpenoids and glycosides in all leaf samples. The results obtained here reveal the antibacterial potentials of the leaf extracts of Carica papaya, Pterocarpus soyauxii, and Vernonia amygdalina, and suggests their possible exploitation for the development of novel herbal-based antimicrobials.

    Pterocarpus soyauxii Taub (Papilionaceae) is used in Cameroonian traditional medicine and pharmacopoeia to treat hypertension, diabetes, gastrointestinal parasitizes and cutaneous diseases. The present investigation was carried out to evaluate the safety of an aqueous stem bark extract of Pterocarpus soyauxii by determining toxicity after acute and sub-chronic oral administration in male and female rodents. The acute toxicity test was conducted in mice. An aqueous extract of barks was administrated by gavage in single doses of 2.5-12.5 g/kg. General behaviour and mortality were examined for up to 7 days. The sub-chronic toxicity test was performed in rats. The plant extract was administered by daily gavage of 150-600 mg/kg for 42 days. Body weight, food and water intakes were followed weekly. Haematological, biochemical and organ parameters were determined at the end of the 42-day administration. In the acute study in mice, oral administration of the aqueous extract of Pterocarpus soyauxii caused dose-dependent general behaviour adverse effects and mortality. The no-observed adverse effect level (NOAEL) of the extract was 5.0 g/kg. The lowest-observed adverse effect level (LOAEL) was 7.5 mg/kg. Mortality increased with the dose, LD(50) was>10.75 g/kg for the mouse. In the sub-chronic study in rats, daily oral administration of the aqueous extract of Pterocarpus soyauxii did not result in death or significant changes in haematological or biochemical parameters, excepted increased hepatic catalase activity (PPterocarpus soyauxii Taub had very low toxicity in oral acute high dose administration and no toxicity in oral sub-chronic low dose administration and indicate that the plant could be considered safe for oral medication.

    The antiplatelet and antioxidative activity of polyphenolic fraction isolated from aerial parts of Tribulus pterocarpus in blood platelets stimulated by thrombin was studied. Thrombin as a strong physiological agonist induces the enzymatic peroxidation of endogenous arachidonic acid, the formation of different reactive oxygen species, including superoxide anion radicals ([Formula: see text](·)) and the platelet aggregation. Therefore, the aim of our study was to assess if the polyphenolic fraction from aerial parts of T. pterocarpus may change the biological properties of blood platelets activated by thrombin. We used cytochrome c reduction method to test the ability of this fraction to change [Formula: see text](·) generation in platelets. Arachidonic acid metabolism was measured by the level of thiobarbituric acid reactive substances (TBARS) and by the production of 8-epi-prostaglandin (8-EPI) F(2). Moreover, we determined the effects of the fraction on blood platelet aggregation induced by thrombin. We observed that the polyphenolic fraction from T. pterocarpus reduced [Formula: see text](·), 8-EPI and TBARS production in these cells. The ability of the fraction to decrease the [Formula: see text](·) generation in blood platelets supports the importance of free radicals in platelet functions, including aggregation process. This study may suggest that the tested plant fraction might be a good candidate for protecting blood platelets against changes of their biological functions, which may be associated with the pathogenesis of different cardiovascular disorders.

    Full Text Available Objective: The study was carried out to perform the pharmacognostic evaluation of Lantana camara Linn. root. Method: The pharmacognostic evaluation was done in terms of organoleptic, macro-microscopy, fluorescence analysis and physicochemical parameters. Results: The characteristic macroscopic features showed that the root consists of 25-40 cm long, 0.2-4.0 cm thick pieces which are usually branched, shallow, tough, creamish-brown externally, outer surface rough due to longitudinal wrinkles, with hard fracture, characteristic odour and pungent taste. The main microscopic characters of the root shows exfoliating cork, consisting of about 10-15 rows of tangentially elongated, thick-walled cells followed by cortex consisting of polygonal parenchymatous cells, a few containing rhomboidal shaped calcium oxalate crystals. Endodermis consists of 3-4 layers of non-lignified, thick-walled rounded parenchymatous cells followed by a single layer of non-lignified pericycle. Phloem, a wide zone of xylem consisting of lignified pitted vessels and bi-to triseriate medullary rays are also present. Proximate physicochemical analysis of the root power showed loss on drying, total ash, water soluble ash, sulphated ash values as 0.52, 4.26, 3.8 and 5.8 % w/w respectively. Successive extraction of the root powder with petroleum ether, chloroform, alcohol, water yielded 0.19, 0.35, 2.19 and 2.0 % w/w respectively. Fluorescence study imparted characteristic colors to the root powder when observed under visible, short and long wavelength light. Conclusions: Various pharmacognostic parameters evaluated in this study helps in identification and standardization of Lantana camara L. root in crude form.

    This study was designed to determine the effects of methanolic extracts of Annona muricata (Linn) on the blood glucose level of streptozotocin-induced diabetic Wistar rats. Thirty adult Wistar rats were randomly assigned into three groups (A, B and C) of ten rats each. Group A was the control, Group B was untreated hyperglycemic group and group C was A. muricata-treated group. Hyperglycemia was induced in groups B and C by a single intraperitoneal injection of 80 mg/kg streptozotocin dissolved in 0.1 M citrate buffer. The control group was intraperitoneally injected with equivalent volume of citrate buffer and all the animals were monitored for four weeks. Daily intra peritoneal injection of 100 mg/kg A. muricata was administered to group C rats for two weeks and the animals were monitored for another two weeks. The data obtained were analyzed with descriptive and inferential statistics. The result showed a mean body weight of 206 +/- 7.74 g, 173.29+/-5.13 g and 197 +/- 5.62 g respectively for the control, untreated diabetic and A. muricata-treated diabetic group, and a mean blood glucose concentration of 3.78 +/- 0.190 mmol/L, 21.64 +/- 2.229 mmol/L and 4.22 +/- 0.151 mmol/L for the control, untreated diabetic and treated diabetic groups respectively. A significant difference exists between the blood glucose concentrations of treated and untreated hyperglycemic groups of rats. The result of this study demonstrated that A. muricata possesses anti-hyperglycemic activities.

    The role of immunomodulation in the therapeutic treatment of visceral leishmaniasis has gained eminence in view of moderate to severe drawbacks of the currently available drugs like toxicity, drug resistance and prohibitive costs. The potential for modulation of the immune system of many herbal plants can be tapped to address these problems. We conducted the present research study to investigate the antileishmanial and immunomodulatory effects of Ocimum sanctum Linn. and Cocos nucifera Linn. during the progression of visceral leishmaniasis in BALB/c mouse model. The IC50 values of the ethanolic leaf extract of O. sanctum and that of the aqueous husk-fibre extract of C. nucifera against the sodium stibogluconate (SSG) susceptible strain (MHOM/IN/80/Dd8) were found to be 73.3 and 62 µg/ml respectively. On treatment of infected BALB/c mice with the extracts, we observed a reduction in hepatic parasite load by 43.63 % (O. sanctum), 65.42 % (C. nucifera) and 75.61 % (O. sanctum + C. nucifera) at 1st post treatment day (p.t.d.), while at 15th p.t.d., the reduction was 73.61 % (O. sanctum), 76.59 % (C. nucifera) and 94.12 % (O. sanctum + C. nucifera). This was accompanied by an up-scaling of the DTH response, skewing of the humoral response towards Th1 type and hepatoprotection in the form of normalization of liver function tests. Overall, administration of the extracts of these two plants in combination as compared to their administration alone rescued the affected mice from the disease greatly, which can be attributed to their antileishmanial and immunomodulatory activities.

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

    Objective: To investigate possible protein targets for antimalarial activity of Garcinia mangostana Linn. (G. mangostana) (pericarp) in 3D7 Plasmodium falciparum clone using 2-dimensional electrophoresis and liquid chromatography mass-spectrometry (LC/MS/MS). Methods: 3D7 Plasmodium falciparum was exposed to the crude ethanolic extract of G.mangostana Linn. (pericarp) at the concentrations of 12µg/mL (IC50 level: concentration that inhibits parasite growth by 50%) and 30 µg/mL (IC90 level: concentration that inhibits parasite growth by 90%) for 12 h. Parasite proteins were separated by 2-dimensional electrophoresis and identified by LC/MS/MS.Results:At the IC50 concentration, about 82% of the expressed parasite proteins were matched with the control (non-exposed), while at the IC90 concentration, only 15% matched proteins were found. The selected protein spots from parasite exposed to the plant extract at the concentration of 12 µg/mL were identified as enzymes that play role in glycolysis pathway, i.e., phosphoglycerate mutase putative, L-lactate dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase, and fructose-bisphosphate aldolase/phosphoglycerate kinase. The proteosome was found in parasite exposed to 30 µg/mL of the extract.Conclusions:Results suggest that proteins involved in the glycolysis pathway may be the targets for antimalarial activity of G. mangostana Linn. (pericarp).

    Since trees and plants can absorb CO2, forests are widely regarded as a carbon sink that may control the amount of CO2 in the atmosphere. The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation (PAR), temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data. The PAR-independent CO2 uptake was then related to air temperature. Finally, the effects of PAR (I) and air temperature (Ta) on the CO2 uptake rate (A) were combined as:A= [(-0.0575 Ta2+ 2.6691 Ta-23.264)I/(-4.8794Ta2+227.13Ta-2456.9)+I](-0.00766Ta2+0.40666Ta-3.99924)

    Numerous plants are known to exhibit considerable biological activities in the fields of medicine and agriculture, yet access to their active ingredients is often complicated, cumbersome and expensive. As a consequence, many plants harbouring potential drugs or green phyto-protectants go largely unnoticed, especially in poorer countries which, at the same time, are in desperate need of antimicrobial agents. As in the case of plants such as the Jericho tomato, Solanum incanum, and the common African tree Pterocarpus erinaceus, nanosizing of original plant materials may provide an interesting alternative to extensive extraction and isolation procedures. Indeed, it is straightforward to obtain considerable amounts of such common, often weed-like plants, and to mill the dried material to more or less uniform particles of microscopic and nanoscopic size. These particles exhibit activity against Steinernema feltiae or Escherichia coli, which is comparable to the ones seen for processed extracts of the same, respective plants. As S. feltiae is used as a model nematode indicative of possible phyto-protective uses in the agricultural arena, these findings also showcase the potential of nanosizing of crude "waste" plant materials for specific practical applications, especially-but not exclusively-in developing countries lacking a more sophisticated industrial infrastructure.

    Botanical larvicides have featured prominently as alternative to synthetic chemical insecticides which are less degradable and toxic to non-target organisms. The larvicidal potentials of the seed oils of Pterocarpus santalinoides and Tropical Manihot species (TMS 30572) were investigated in the laboratory against larvae of Aedes aegypti. The seed oil of each plant was extracted using n-hexane and was graded into different concentrations; 30, 60, 90, 120 and 150 ppm. The toxicity of each of the concentrations was evaluated against 3rd instar larvae of A. aegypti and tadpoles (Buffo spp) as non target aquatic fauna. Both oils were toxic to the larvae though at higher concentrations (120 ppm and 150 ppm) after 24 hours of exposure. The oil of P. santalinoides was more toxic to the larvae (LC50 104.0 ppm and LC90 184.5 ppm) than oil of TMS (LC50 113.5 and LC90 201.2) but the difference in the lethal doses was not statistically significant (P > 0.05). However, mortality was not recorded at any of the graded concentrations in both oils against tadpoles. The results therefore suggest that the seed oils of both plants could be incorporated as botanical insecticides against mosquito vectors with high safety to non-target organisms.

    We analysed the molecular diversity of Pterocarpus officinalis, a tree species distributed in Caribbean islands, South and Central America to quantify the genetic variation within island, to assess the pattern of differentiation and infer levels of gene flow; with the overall goal of defining a strategy of conservation. Two hundred two individuals of 9 populations were analysed using three chloroplast and six nuclear microsatellite markers. The observed heterozygosity varied markedly among the populations for nuclear (H(Onuc )= 0.20-0.50) and chloroplast microsatellites (H (cp )= 0.22-0.68). The continental population from French Guyana showed a higher value of H(Onuc) than island populations, and the differences were significant in some cases. The fixation index F (IS) ranged from -0.043 to 0.368; a significant heterozygote deficit was detected in 7 populations. The heterozygosity excess method suggested that two populations in Guadeloupe have undergone a recent bottleneck. Global and pairwise F (ST) were high for both nuclear (F(STnuc )= 0.29) and chloroplast microsatellites (F(STcp )= 0.58). The neighbour-joining tree based on both markers, presented a differentiation pattern that can be explained by the seed dispersal by flotation and marine stream. The comparison of Bayesian approach and the method based on allelic frequency demonstrate a very limited number of migrants between populations.

    Natural polymers can be extracted from leaf or stem of plants. Pterocarpus Indicus W. (PIW) and Jatropha Multifida L. (JIL) plants are good candidate as natural polymer sources. PIW and JIW polymers contain chemical compound so-called flavonoids which has C6-C3-C6 carbons conjugated configuration. The renewable type of polymer as well as their abundancy of flavonoid provide us to explore their physical properties. A number of research have been reported related to broad synthesis method and mechanical properties. So far there is no specific report of electrical conductivity associated to PIW and JIL natural polymers. In order to obtain electrical conductivity and its crystallinity of the extracted polymer films, it was induced on them a various fraction of silver nano particles. The film has been prepared by means of spin coating method on nickel substrate. It was revealed that FTIR spectra confirm the existing of rutine flavonoid. The crystallinity of the samples increase from 0.66%, to 4.11% associated to the respective various of silver fractions of 0.1 M to 0.5 M. SEM images show that there are some grains of silver in the film. The nature of electric conductivity increases a long with the addition of silver. The electrical conductivity increase significantly from 3.22 S/cm, to 542.85 S/cm. On the other hand, PIW films also shows similar trends that increase of Ag induce the increase its crystallinity as well as its electrical conductivity at semiconducting level. This result opens a prospective research and application of the green renewable polymer as optoelectronic materials.

    The incidence of arthritis is quite high and there is a need for the search of natural products to halt the progression of disease or provide symptomatic relief without significant adverse effects. This study aimed at evaluating the anti-inflammatory and analgesic activities of topical Pterocarpus santalinus in an animal model of chronic inflammation. Albino rats of either sex were divided into five groups of six rats each (Group I - Control, Group II -Gel base, Group III -P. santalinus paste, Group IV -P. santalinus gel, Group V- Diclofenac gel). Chronic inflammation was induced on day 0 by injecting 0.1 ml Complete Freund's Adjuvant (CFA) in sub-plantar tissue of left hind paw of the rats. Topical treatment was started from day 12 till day 28. Body weight and paw volume (Plethysmometer) were assessed on day 0, 12 and 28. Pain assessment was done using Randall and Selitto paw withdrawal method. Data was analysed using GraphPad Prism version 5. Unpaired students t-test and ANOVA followed by Tukey's test was used for comparison among groups. Only topical P.santalinus gel significantly reduced the body weight (p=0.02) due to reduction in inflammatory oedema of the left limb. P. santalinus gel also showed significant reduction (p=0.03) in paw volume of rats compared to the other groups. There was significant reduction in pain threshold (gm/sec) due to chronic inflammation, with all the study drugs (p<0.05) but with P. santalinus gel, this reduction was less (p<0.001). Gel showed significant anti-inflammatory and mild analgesic activity on topical application in rat model of chronic inflammation.

    The larvicidal effects of the crude protein extract and purified toxin, Jc-SCRIP, from the seed coat of Jatropha curcas Linn. against the third instar larvae of mosquitoes, Aedes aegypti Linn. and Culex quinquefasciatus Say, were investigated. This test compared the effects of the purified toxin with crude protein extracts from seed kernels of J. curcas and Ricinus communis. At various concentrations of purified toxin and crude protein extract, the larval mortality of both Ae. aegypti and Cx. quinquefasciatus were positively correlated with increased exposure time. The larvae of Cx. quinquefasciatus were more susceptible to the toxin and both extracts than the larvae of Ae. aegypti. After 24 hours of exposure, the extract showed larvicidal activity against Ae. aegypti and Cx. quinquefasciatus with (LC50) values of 3.89 mg/ml and 0.0575 mg/ml, respectively. The toxin, Jc-SCRIP, showed larvicidal activity against Ae. aegypti and Cx. quinquefasciatus with (LC50) values of 1.44 mg/ml and 0.0303 mg/ ml, respectively. These results indicated that the crude protein extract and Jc-SCRIP were more toxic to the third instar larvae of Cx. quinquefasciatus than that of Ae. aegypti. The potent larvicidal activities of the seed coat extract and the Jc-SCRIP toxin from J. curcas suggest that they may be used as bioactive agents to control the mosquito population.

    Instrumental weather records in southern Africa are largely limited to the last 100 years and documentary weather-related data are rare prior to the 1800s, hindering our understanding of the natural and/or anthropogenic factors that influence climate variability over this region. Measuring stable isotopes ratios (commonly 13C/12C and 18O/16O) in tree rings can provide a good proxy for extending climate data beyond the instrumental record. The objective of this study is to characterize historical variations in the climatology underlying extreme climatic events in Zimbabwe using instrumental climate records (precipitation and temperature) and a multi-proxy approach (ring width, δ18O, and δ13C) for dendroclimatic proxy reconstructions. A 90-year (1900-1990) δ18O and δ13C tree ring record using four Pterocarpus angolensis samples is being developed and compared to tree ring width, monthly, seasonal, and annual precipitation totals, meteoric water δ18O values, and mean monthly and seasonal temperature. Preliminary results indicate significant correlations between the average δ18O record and the previous year December precipitation totals (r=0.41, p<0.0001), current year January precipitation totals (r=0.45, p<0.0001), and combined total precipitation for the previous year November and December and current year January (r=0.57, p<0.0001). Furthermore, we find that the δ18O values are strongly influenced by maximum temperature during the previous year December (r=0.39, p=0.0001) and current year January (r=0.40, p=0.0001), and average maximum temperature during the months of the previous year December and current year January and February (r=0.47, p<0.001). We thus present one of the first studies to integrate a multi-proxy approach to investigate historical climate variability in southern Africa using ring widths, and tree ring δ18O and δ13C values of trees growing in Zimbabwe.

    Background The study of traditional knowledge of medicinal plants has led to discoveries that have helped combat diseases and improve healthcare. However, the development of quantitative measures that can assist our quest for new medicinal plants has not greatly advanced in recent years. Phylogenetic tools have entered many scientific fields in the last two decades to provide explanatory power, but have been overlooked in ethnomedicinal studies. Several studies show that medicinal properties are not randomly distributed in plant phylogenies, suggesting that phylogeny shapes ethnobotanical use. Nevertheless, empirical studies that explicitly combine ethnobotanical and phylogenetic information are scarce. Methodology/Principal Findings In this study, we borrowed tools from community ecology phylogenetics to quantify significance of phylogenetic signal in medicinal properties in plants and identify nodes on phylogenies with high bioscreening potential. To do this, we produced an ethnomedicinal review from extensive literature research and a multi-locus phylogenetic hypothesis for the pantropical genus Pterocarpus (Leguminosae: Papilionoideae). We demonstrate that species used to treat a certain conditions, such as malaria, are significantly phylogenetically clumped and we highlight nodes in the phylogeny that are significantly overabundant in species used to treat certain conditions. These cross-cultural patterns in ethnomedicinal usage in Pterocarpus are interpreted in the light of phylogenetic relationships. Conclusions/Significance This study provides techniques that enable the application of phylogenies in bioscreening, but also sheds light on the processes that shape cross-cultural ethnomedicinal patterns. This community phylogenetic approach demonstrates that similar ethnobotanical uses can arise in parallel in different areas where related plants are available.

    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.

    Full Text Available In the present study, the hepatoprotective activity of ethanolic extracts of Cassia sophera Linn. leaves was evaluated against carbon-tetrachloride- (CCl4- induced hepatic damage in rats. The extracts at doses of 200 and 400 mg/kg were administered orally once daily. The hepatoprotection was assessed in terms of reduction in histological damage, changes in serum enzymes, serum glutamate oxaloacetate transaminase (AST, serum glutamate pyruvate transaminase (ALT, serum alkaline phosphatase (ALP, total bilirubin, and total protein levels. The substantially elevated serum enzymatic levels of AST, ALT, ALP, and total bilirubin were restored towards the normalization significantly by the extracts. The decreased serum total protein level was significantly normalized. Silymarin was used as standard reference and exhibited significant hepatoprotective activity against carbon tetrachloride-induced hepatotoxicity in rats. The biochemical observations were supplemented with histopathological examination of rat liver sections. The results of this study strongly indicate that Cassia sophera leaves have potent hepatoprotective action against carbon tetrachloride-induced hepatic damage in rats. This study suggests that possible activity may be due to the presence of flavonoids in the extracts.

    Full Text Available Actaea spicata Linn. (Ranunculaceae has been traditionally used for the treatment of various ailments such as rheumatism, inflammation, nerve diseases, lumbago, scrofula and chorea. Despite a long tradition of use, no systematic phytochemical and pharmacological work has been carried out on this potential plant. Thus, A. spicata was subjected to preliminary anti-anxiety screening studies, with a view to ascertain the verity of its traditional use as an anxiolytic. In the present investigation, roots of the plant were extracted using solvents in order of increasing polarity viz., petroleum ether (60-80C, chloroform, methanol and distilled water. All the crude extracts were evaluated for anti-anxiety activity in mice using elevated plus maze apparatus. Among all these extracts, only methanol extract exhibited significant anti-anxiety activity at a dose of 100 mg/kg in mice with respect to control as well as standard (diazepam, 2 mg/kg. Phytochemical screening showed presence of alkaloids and polyphenols in methanol extract of A. spicata. Thus, Specific methods were adopted to extract total alkaloidal and polyphenol fractions from the plant material and methanol extract of plant, respectively. Polyphenol fraction exhibited significant anxiolytic activity at the dose of 50 mg/kg, while alkaloidal fraction was found to be devoid of any activity.

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

    Full Text Available Malaria parasites are increasingly becoming resistant to currently used antimalarial therapies, therefore there is an urgent need to expand the arsenal of alternative antimalarial drugs. In addition, it is also important to identify novel antimalarial drug targets. In the current study, extracts of two plants, Pterocarpus angolensis and Ziziphus mucronata were obtained and their antimalarial functions were investigated. Furthermore, we explored the capability of the extracts to inhibit Plasmodium falciparum heat shock protein 70 (Hsp70 function. Heat shock protein 70 (Hsp70 are molecular chaperones whose function is to facilitate protein folding. Plasmodium falciparum the main agent of malaria, expresses two cytosol-localized Hsp70s: PfHsp70-1 and PfHsp70-z. The PfHsp70-z has been reported to be essential for parasite survival, while inhibition of PfHsp70-1 function leads to parasite death. Hence both PfHsp70-1 and PfHsp70-z are potential antimalarial drug targets. Extracts of P. angolensis and Z. mucronata inhibited the basal ATPase and chaperone functions of the two parasite Hsp70s. Furthermore, fractions of P. angolensis and Z. mucronata inhibited P. falciparum 3D7 parasite growth in vitro. The extracts obtained in the current study exhibited antiplasmodial activity as they killed P. falciparum parasites maintained in vitro. In addition, the findings further suggest that some of the compounds in P. angolensis and Z. mucronata may target parasite Hsp70 function.

    Full Text Available The West African Chimpanzee Pan troglodytes verus is Endangered (A4cd ver 3.1 in Senegal (Humle et al. 2008, mainly due to habitat fragmentation and destruction. We gathered qualitative and quantitative data on the tree species preferences of the West African Chimpanzee for nest building in order to gain insight into habitat dependence. Between March 1998 and Febrary 2000 we identified tree species in which a sample of 1790 chimpanzee nests had been built, and ranked species in preference order. We compared this sample to the relative abundance of tree species in the chimpanzee habitat to determine whether particular species were chosen for nesting. We observed that about a quarter (25.42% of nests were built in Pterocarpus erinaceus, which is considerably greater than would be expected from the abundance of this species in the habitat (6.35%, indicating a strong preference by chimpanzees. We examined the physical traits of the most-used tree species and concluded that height and wood hardness may be key choice features. P. erinaceus is threatened in Senegal due to extensive cutting, which may endanger chimpanzees living outside the boundaries of protected areas. In the current anthropogenic setting our results provide conservation managers with information on how to protect a key aspect of the chimpanzee natural environment.

    Aim of the Study: The aim is to evaluate the hypoglycemic and antidiabetic effects of aqueous and CH2Cl2/CH3OH stem bark extracts of Pterocarpus soyauxii Taub in normal and diabetic rats. Materials and Methods: Streptozotocin (STZ)-induced diabetic and normal adult Wistar rats were orally administered with aqueous and CH2Cl2/CH3OH plant extracts of P. soyauxii at various doses (38–300 mg/kg) in a single administration. In addition, STZ-induced diabetic rats received prolonged daily administration for 14 days. Glibenclamide (GB) (10 mg/kg) was used as reference treatment. In acute test, fasting blood glucose was followed for 5 h. In subacute test, body weight, food and water intakes, and blood glucose were followed weekly and serum biochemical parameters evaluated after 14 days treatment. Results: Acute administration of aqueous and CH2Cl2/CH3OH stem bark extracts moderately decreased fasting blood glucose compared to GB, significantly in normal rats (P Sodium chloride; K3Fe(CN)6: Potassium ferricyanide; ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; H: Hour; BW: Body weight, W1 and W2: Weeks 1 and 2; CHOD: Cholesterol oxidase; GPO: Glycerol-3 Phosphate oxidase; PAP: Phenol + Aminophenazone

    The present study was designed to investigate the effect of bark of Pterocarpus santalinus, an ethnomedicinal plant, on blood glucose, plasma insulin, serum lipids and the activities of hepatic glucose metabolizing enzymes in streptozotocin-induced diabetic rats. Streptozotocin-induced diabetic rats were treated (acute/short-term and long-term) with ethyl acetate:methanol fractions of ethanolic extract of the bark of P. santalinus. Fasting blood glucose, HbA(1C), plasma insulin and protein were estimated before and after the treatment, along with hepatic glycogen, and activities of hexokinase, glucose-6-phosphatase, fructose-1,6-bisphosphatase and glucose-6-phosphate dehydrogenase. Further anti-hyperlipidemic activity was studied by measuring the levels of serum lipids and lipoproteins. Phytochemical analysis of active fraction showed the presence of flavonoids, glycosides and phenols. Biological testing of the active fraction demonstrated a significant antidiabetic activity by reducing the elevated blood glucose levels and glycosylated hemoglobin, improving hyperlipidemia and restoring the insulin levels in treated experimental induced diabetic rats. Further elucidation of mechanism of action showed improvement in the hepatic carbohydrate metabolizing enzymes after the treatment. Our present investigation suggests that active fraction of ethanolic extract of bark of P. santalinus decreases streptozotocin induced hyperglycemia by increasing glycolysis and decreasing gluconeogenesis.

    Full Text Available Pterocarpus officinalis (Jacq. is a leguminous forestry tree species endemic to Caribbean swamp forests. In Guadeloupe, smallholder farmers traditionally cultivate flooded taro (Colocasia esculenta cultures under the canopy of P. officinalis stands. The role of arbuscular mycorrhizal (AM fungi in the sustainability of this traditional agroforestry system has been suggested but the composition and distribution of AM fungi colonizing the leguminous tree and/or taro are poorly characterized. An in-depth characterization of root-associated AM fungal communities from P. officinalis adult trees and seedlings and taro cultures, sampled in two localities of Guadeloupe, was performed by pyrosequencing (GS FLX+ of partial 18S rRNA gene. The AM fungal community was composed of 215 operational taxonomic units (OTUs, belonging to eight fungal families dominated by Glomeraceae, Acaulosporaceae, and Gigasporaceae. Results revealed a low AM fungal community membership between P. officinalis and C. esculenta. However, certain AM fungal community taxa (10% of total community overlapped between P. officinalis and C. esculenta, notably predominant Funneliformis OTUs. These findings provide new perspectives in deciphering the significance of Funneliformis in nutrient exchange between P. officinalis and C. esculenta by forming a potential mycorrhizal network.

    Full Text Available This article points to the responsibility historians have in the formation of what we may call the collective memory of persons, groups and states. What are the images of “the other” conveyed in textbooks and media? In Norway, the historian Tore Linné Eriksen has – more than any other scholar – used his research, writings and enormous capacity for work to educate students, youth and the public in general and to create a more just image of “the other”. His driving force has been an extraordinary ability to be at the forefront in spotting international research, as well as his sense of justice and respect for the non-western world. His last extensive work on global history (Globalhistorie 1750–1900 clearly demonstrates these capabilities.In the early 1980s, long before the wave of genocide studies after the Rwanda catastrophe of 1994, Eriksen’s two works on Namibia –Namibia: Kolonialisme, apartheid og frigjøringskamp i det sørlige Afrika (1982 and The Political Economy of Namibia: An Annotated Critical Bibliography (1985 – used the concept of genocide to describe German conduct in Namibia in the early 20th century. In 2007, Eriksen published his book about what he calls the first genocide of the 20th century, Det første folkemordet i det tjuende århundret. Namibia 1903–1908. German and African history is woven into the question of whether the dangerous relations that developed between German settlers and Africans can be labelled genocide. The present article attempts to present Eriksen’s arguments. An introductory section deals with the trends in the international research literature and establishes a link between colonialism and genocide. In 2008, Eriksen’s article on the extinction of the Herero people in Namibia – “Utslettelse av Hererofolket i Namibia 1903– 1908” – was published in Bernt Hagtvets collection of articles, Folkemordenes svarte bok. The following year, Tore Linné Eriksen’s article in the

    Full Text Available Herbal and natural products of folk medicine have been used for centuries in every culture throughout the world. Scientists and medical professionals have shown increased interest in this field as they recognize the true health benefits of these remedies. “Let food be your medicine and let medicine be your food” was advised by the father of medicine, Hippocrates, over two million ago. It’s still true today that “you are what you eat.” Spinach is a leafy green vegetable that came originally from south-western Asia and is now grown in most parts of the world. Scientifically it is known as Spincia oleracea Linn. (Family-Chenopodiaceae. Though Spinach is most often used as a food, it has medicinal value as well. Spinach is packed with vitamins such as vitamin C, vitamin A and vitamin E and minerals like magnesium, manganese, iron, calcium and folic acid. Spinach is also a good source of chlorophyll, which is known to aid in digestion. Spinach is also rich in the carotenoids beta-carotene and lutein. It is a good source of the bioflavonoid quercetin with many other flavonoids which exhibits anti-oxidant, antiproliferative, antiinfammatory, antihistaminic, CNS depressant, protection against gamma radiation, hepatoprotective properties in addition to its many other benefits. Spinach is also used to prevent the bone loss associated with osteoporosis and for its anti-inflammatory properties in easing the pain of arthritis. Spinach is good for the heart and circulatory system and has energy-boosting properties. Spinach is truly one of nature's most perfect foods.

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

    Objective:To study the leaf epidermis of wild and micropropagated Dioscorea bulbifera Linn. (D. bulbifera) in order to document useful diagnostic features that may be employed for correct crude drug identification and to clear any taxonomic uncertainties in the micropropagated medicinal plant. Methods:Growth responses of micropropagated D. bulbifera were observed on Murashige Skoog medium supplemented with 6-benzylamino purine (1.0 mg/L)+α-naphthaleneacetic acid (0.2 mg/L)+cysteine (20 mg/L) using nodal segments as explants. Leaves of the wild and micropropagated plants were studied microscopically. Results: More than 80%shoot regeneration and formation of 10%-30%whitish-brown callus were observed within 3 weeks. The highest root proliferation was obtained from Murashige Skoog medium of 6-benzylamino purine (0.05 mg/L) and α-naphthaleneacetic acid (0.01 mg/L) with mean root length of (27.00±1.25) mm and elongated single shoot of mean length (38.00±11.09) mm. Leaf epidermal features that revealed similarities between the wild and micropropagated plants included amphistomatic condition, presence of mucilage, glandular unicellular trichome with multicellular head, polygonal cells with smooth walls, stomata type and shape. Slight variations included thick cuticular wall with closed stomata in wild plant compared to thin walled opened stomata in the in vitro plant. Opening of stomata accounted for larger average stomata sizes of (7.68±0.38) µm and (6.14±0.46) µm on the adaxial and abaxial surfaces, respectively of the micropropagated plant compared to the wild. Conclusions: The diagnostic features obtained in the study could serve as a basis for proper identification for quality control for standardization of the medicinal plant.

    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.

    Tribulus is a well-known pharmaceutical herb that has been used for a long time in the traditional Chinese and Indian systems of medicine for the treatment of various diseases. It has been found that the genus Tribulus is rich in biologically active furostane-, cholestane- and spirostane-type steroidal saponins. To develop a rapid, sensitive and accurate method based on liquid-phase extraction followed by high-performance liquid chromatography and electrospray ionisation mass spectrometry (HPLC-ESI-MS) to identify different saponins in three species of the genus Tribulus, and to quantify the compounds that are already known. After extraction from the species studied, the extracts were subjected to HPLC analyses with an XTerra® MS C(18) -column and a binary mobile phase consisting of 0.05% formic acid in water and acetonitrile, and with an ESI-MS detection in the negative ion mode. Data were acquired and processed using the Xcalibur 1.3 software. The results exhibited that the profiles of native steroidal glycosides of both T. pentandrus and T. megistopterus subsp. pterocarpus were very similar to each other, but that of T. parvispinus was remarkably different. The fragmentation patterns provided evidence that the saponins possess spirostane-, cholestane- and furostane-type aglycones. Quantitative analyses suggested that these species are a rich source of steroidal saponins. HPLC-ESI-MS/MS allowed identification of the key compounds without preparative isolation of the components from the crude extract of Tribulus species. Copyright © 2012 John Wiley & Sons, Ltd.

    Pterocarpus officinalis Jacq. is a legume tree native to the Caribbean islands and South America growing as a dominant species in swamp forests. To analyze (i) the genetic diversity and (ii) the symbiotic properties of its associated nitrogen-fixing soil bacteria, root nodules were collected from P. officinalis distributed in 16 forest sites of the Caribbean islands and French Guiana. The sequencing of the 16S-23S ribosomal RNA intergenic spacer region (ITS) showed that all bacteria belonged to the Bradyrhizobium genus. Bacteria isolated from insular zones showed very close sequence homologies with Bradyrhizobium genospecies V belonging to the Bradyrhizobium japonicum super-clade. By contrast, bacteria isolated from continental region displayed a larger genetic diversity and belonged to B. elkanii super-clade. Two strains from Puerto Rico and one from French Guiana were not related to any known sequence and could be defined as a new genospecies. Inoculation experiments did not show any host specificity of the Bradyrhizobium strains tested in terms of infectivity. However, homologous Bradyrhizobium sp. strain-P. officinalis provenance associations were more efficient in terms of nodule production, N acquisition, and growth than heterologous ones. The dominant status of P. officinalis in the islands may explain the lower bacterial diversity compared to that found in the continent where P. officinalis is associated with other leguminous tree species. The specificity in efficiency found between Bradyrhizobium strains and host tree provenances could be due to a coevolution process between both partners and needs to be taken in consideration in the framework of rehabilitation plantation programs.

    Novel hepatoprotectives are needed to address the increasing cases of liver problems worldwide. Pterocarpus erinaceus Poir (Fabaceae) ethanol stem bark extract (PE) and its constituent flavonoid, homopterocarpin (HP), were investigated for their protective property in acetaminophen-induced oxidative stress and liver damage. Adult male albino rats were divided into nine groups. Seven groups were pretreated with PE (50-, 100-, and 150 mg/kg), HP (25-, 50-, and 75 mg/kg) or silymarin (25 mg/kg), respectively, once daily for 5 consecutive days and then administered acetaminophen (2 g/kg) on the 5th day. The control and acetaminophen-intoxicated groups received normal saline throughout the experimental period, with the latter group additionally receiving 2 g/kg acetaminophen on the 5th day. Administrations were performed po. In the acetaminophen-intoxicated group, there were significant increases (p<0.05) in serum activities of alanine aminotransferase (31.72±3.3 vs. 22.1±1.2 U/I), aspartate aminotransferase (185.1±10.1 vs. 103.83±13.3 U/I), bilirubin level and hepatic malondialdehyde (2.32±0.3 vs. 1.42±0.1 units/mg protein), accompanied with significant decreases (p<0.05) in hepatic reduced glutathione level (0.10±0.01 vs. 0.23±0.03 units/mg protein) and glutathione peroxidase activity (2.51±0.2 vs. 3.25±0.2 μmol H2O2 consumed/min/mg protein) compared with the control. PE and HP ameliorated most of the observed biochemical alterations with HP appearing to show more potency. The results suggest that the flavonoid, homopterocarpin contributes to the hepatoprotective and antioxidant potentials of P. erinaceus extract.

    Alzheimer's disease is a neurodegenerative disorder associated with a decline in cognitive abilities. Dementia is one of the age-related mental problems and a characteristic symptom of Alzheimer's disease. Nootropic agents are used in situations where there is organic disorder in learning abilities. The present work was undertaken to assess the potential of Foeniculum vulgare Linn. extract as a nootropic and anticholinesterase agent in mice. Methanolic extract of the whole plant of F. vulgare Linn. administered for eight successive days ameliorated the amnesic effect of scopolamine (0.4 mg/kg) and aging- induced memory deficits in mice. The passive avoidance paradigm served as the exteroceptive behavioral model for assessing memory. F. vulgare extract increased step-down latency and acetylcholinesterase inhibition in mice significantly. Hence, F. vulgare can be employed in treatment of cognitive disorders such as dementia and Alzheimer's disease.

    Full Text Available Problem statement: The formation of a urinary stone, known as nephrolithiasis, urolithiasis, renal calculi or kidney stone is a serious, debilitating problem in all societies throughout the world. Struvite or Ammonium Magnesium Phosphate Hexahydrate (AMPH is one of the components of urinary stone (calculi. Struvite stones are commonly found in women. Struvites form in humans as a result of urinary tract infection with ureolithic urea splitting micro organisms. These stones can grow rapidly forming "staghorn-calculi", which is more painful urological disorder. Therefore, it is of prime importance to study the growth and inhibition of Struvite crystals. Approach: This in vitro study had been carried out in the presence of herbal extract of Boerhaavia diffusa Linn. by using single diffusion gel growth technique. Sodium metasilicate solution of specific gravity 1.05 and an aqueous solution of ammonium dihydrogen phosphate of 0.5 M concentration were mixed so that the pH value 7.0 could be set. After the gelation, equal amount of supernatant solution of 1.0 M magnesium acetate prepared with 0.5 and 1% concentrations of the herbal extract of B. diffusa Linn. were gently poured on the set gels in the respective test tubes in the aseptic medium. Results: The growth of crystals without and with herbal extracts was monitored at regular time intervals. As the concentration of B. diffusa Linn. increased, the inhibition of crystals also increased in the gel media as well as the dissolution of crystals at the gel-liquid interface increases. The de-fragmentation of some grown crystals was also noticed. Conclusion: The herbal extract of B. diffusa Linn. inhibited the growth of struvite crystals in vitro. This study incorporated multidisciplinary interests and may be used for formulating the strategy for prevention or dissolution of urinary stones.

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

    Full Text Available Haridra (Curcuma longa Linn (Zingiberaceae family is a rhizomatous household spice and has been a widely used herb in India since ancient times. Ayurvedic pharmacodynamics of C. longa are described as follows: Rasa - tikta and katu, Guna - rukhsha and laghu, Virya - ushna, Vipak - katu and Doshaghnata - tridoshshamak. It is used as a tonic, carminative, antidiarrheal, hepatoprotective and as a purifying agent. It is also used in cancer management. Since years, haridra has been used as a hemostyptic agent. However, the oncopreventive aspect of haridra has drawn the scientists towards it. Use of haridra in medoja arbuda is documented in Sushrut Samhita. Recently, it has been found that chronic inflammation has played a role in cancer formation. The kapha and vata shamaka property is responsible for the shothghna activity of haridra. Several studies have also proved the anti-inflammatory condition of haridra. The essential oil, containing ar-turmerone, as a major component has been shown to possess anti-inflammatory effect of haridra. Experimental studies ′in vitro and in vivo′ in diverse models have also proved the anti-tumor activity of haridra. Curcumin,the chief ingredient, of it is mainly responsible for anticancer property. However other constituents like Turmerone and polysacchrides also play a major role in anti cancer activity. The free radical scavenging activity as well as inhibition of lipid peroxidation by curcumin has been reported by Kuttan et al. The mechanisms underlying the anticancer potential of curcumin are complex. Many reports in literature mention about that work carried out regarding the suppression of proliferation of cells of different tumors. They include the down regulation of transcription factors, inhibiting COX2, LOX, inducible nitric oxide synthase, matrix metalloproteinases 9, cell adhesion molecules along with TNF-α. Curcumin inhibits TNF-α-induced AKT activation whereby levels required for NFkβ gene

    Objective: To investigate the hepatoprotective activity of ethanolic and aqueous extract of Sesbania grandiflora(Linn) flower in CCl4 induced hepatotoxicity models in rats. Methods:The ethanolic and aqueous extract of Sesbania grandiflora (Linn) flower are screened for its hepatoprotective activity in CCl4 (0.5 ml/kg, i.p) induced liver damage in Swiss albino rats at a dose of 200 mg/kg bw. Results: The ethanolic and aqueous extract of Sesbania grandiflora (Linn) flower significantly (P<0.001) decreases the biochemical parameters (SGOT, SGPT, ALP, TP, and TB). Silymarin (25 mg/kg), a known hepatoprotective drug used for comparison exhibited significant activity (P<0.001). The extract did not shown any mortality up to a dose of 2000 g/kg bw. These findings suggest that the ethanolic and aqueous extract of Sesbania grandiflora (Linn) flower (500mg/kg) was effective in bringing about functional improvement of hepatocytes. The healing effect of this extract was also confirmed by histological observations. Conclusions: The ethanolic extract at doses of 250 and 500 mg/kg, p.o. and aqueous extract at a dose of 500 mg/kg, p.o. of Sesbania grandiflora (Linn) flower have significant effect on the liver of CCl4 induced hepatotoxicity animal models.

    Study was undertaken to compare Cr accumulation in two ferns (Adiantum capillus-veneris Linn. and Microsorium punctatum (Linn.) Copel) and the role of antioxidants were also investigated towards metal tolerance in order to assess the use of ferns in phytomediation/ phytostabilization. Different concentrations (0, 50, 100, 150 microg g(-1) dw) of Cr were added to fern planted in pot containing 1 kg soil. In both the ferns, Cr accumulation increased with increase in metal concentration and maximum accumulation of 800.5 microg g(-1) (fronds) and 1457.4 microg g(-1) (roots) in M. punctatum and 660.8 microg g(-1) (fronds) and 1259.6 microg g(-1) (roots) in A. capillus-veneris was recorded. The increase in the levels of malondialdehyde, antioxidants and antioxidant enzymes (superoxide dismutase, glutathione peroxidase) in A. capillus-veneris was less pronounced than M. punctatum under Cr exposure as compared to their respective controls. In view of less decrease in chlorophyll content and antioxidants along with higher accumulation of Cr in the fronds M. punctatum, is indicative of its higher tolerance towards Cr. However, bioaccumulation factor (concentration of Cr in fronds/concentration of Cr in the soil) of both the ferns was recorded > 1 which qualifies the plants as potential Cr hyperaccumulator and suitable for phytoremediaton.

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

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

    Neutrophils play an important role in the pathogenesis of rheumatoid arthritis (RA) and various inflammatory conditions, by accumulation and liberation of active proteolytic enzymes. The effect of milk extract of Semecarpus anacardium Linn. nuts (SA) at a dosage of 150 mg kg(-1) body weight day(-1) for 14 days on adjuvant arthritis was studied to gain some insight into this intriguing disease in relation to neutrophil functions. The decreased phagocytic function of neutrophils (phagocytic index and avidity index) found in adjuvant arthritis was significantly increased by the administration of the drug SA. Increased levels of reactive oxygen species (superoxide radical, hydroxyl radical, H2O2 and myeloperoxidase), lysosomal enzymes (acid phosphatase and cathepsin D) and increased accumulation of neutrophils in the joints observed in adjuvant arthritic animals were reverted back to near normal levels by treatment with SA. The results of this study indicate that SA can be considered to be a good therapeutic agent for inflammation and arthritis.

    Extracts from Justicia adhatoda L. (Acanthaceae) strongly reduced the fitness of the mosquito, Aedes aegypti Linn. The methanolic extracts inhibited several enzymes responsible for protecting insects from oxidative and other damage, including glutathione-S-transferase, superoxide dismutase, cytochrome P450, and α- and β-esterases. They increased repellency (maximum repellency at 100 ppm) in host-seeking adult females using the "arm-in cage assay." Histopathological examination showed the extracts led to serious midgut cell damage. Justicia adhatoda extracts led to reduced fecundity and oviposition of gravid females compared to controls. The extracts led to substantially reduced A. aegypti survival. We infer that the extracts have potential to reduce pathogen transmission by suppressing population growth of A. aegypti, and possibly other mosquito species.

    Full Text Available Summary: Phyllanthus emblica Linn. (Euphorbiaceae is an herbal plant commonly used in Asian traditional medicine systems for treatment of many disorders. In the present study, we investigated for the first time acute and chronic toxicity of the standardized water extract of P. emblica fruit. The water extract of P. emblica was prepared according to the Thai Herbal Pharmacopoeia and standardized to 20% gallic acid. For studying acute toxicity study, single oral dose of 5000 mg water extract /kg body weight was administered to Sprague Dawley rats (five females, five males. The results showed no toxicity in terms of general behavior change, mortality, or change in gross appearance of internal organs (LD50 > 5,000 mg/kg. Chronic toxicity was studied by daily oral dose (ten females, ten males of 300, 600 and 1,200 mg/kg for 270 days. The results showed slightly significant differences in the body and organ weights between the control and treatment groups. In addition, the rats were analyzed for final body and organ weights, necropsy, and hematological, blood chemical and histopathological parameters. Hematological analysis and clinical blood chemistry revealed slightly changes, but were within the normal limits. No gross or histopathology findings were observed in the treatment groups. Altogether, the standardized water extract from the fruit of P. emblica did not produce acute and chronic toxicity in its traditional uses. Industrial relevance: Traditional medicine is still stronghold of more than 50% of the world population, especially in developing countries. Nowadays, a number of medicinal plants (such as Phyllanthus emblica Linn. are commercially available on local markets as a tonic, food and/or dietary supplement product commonly used for clinical management of several conditions. Despite the widespread use of this plant, there is still little literature on the scientific evaluation of their toxicity. Results of the current study provide

    Indiscriminate use of synthetic insecticides to eradicate mosquitoes has caused physiological resistance. Plants provide a reservoir of biochemical compounds; among these compounds some have inhibitory effect on mosquitoes. In the present study the larvicidal, adulticidal and genotoxic activity of essential oil of Psoralea corylifolia Linn. against Culex quinquefasciatus Say was explored. Essential oil was isolated from the seeds of P. corylifolia Linn. Larvicidal and adulticidal bioassay of Cx. quinquefasciatus was carried out by WHO method. Genotoxic activity of samples was determined by comet assay. Identification of different compounds was carried out by gas chromatography- mass spectrometry analysis. LC50 and LC90 values of essential oil were 63.38±6.30 and 99.02±16.63 ppm, respectively against Cx. quinquefasciatus larvae. The LD50 and LD90 values were 0.057±0.007 and 0.109±0.014 mg/cm2 respectively against adult Cx. quinquefasciatus,. Genotoxicity of adults was determined at 0.034 and 0.069 mg/cm2. The mean comet tail length was 6.2548±0.754 μm and 8.47±0.931 μm and the respective DNA damage was significant i.e. 6.713% and 8.864% in comparison to controls. GCMS analysis of essential oil revealed 20 compounds. The major eight compounds were caryophyllene oxide (40.79%), phenol,4-(3,7-dimethyl-3-ethenylocta-1,6-dienyl) (20.78%), caryophyllene (17.84%), α-humulene (2.15%), (+)- aromadendrene (1.57%), naphthalene, 1,2,3,4-tetra hydro-1,6-dimethyle-4-(1-methyl)-, (1S-cis) (1.53%), trans- caryophyllene (0.75%), and methyl hexadecanoate (0.67%). Essential oil obtained from the seeds of P. corylifolia showed potent toxicity against larvae and adult Cx. quinquefasciatus. The present work revealed that the essential oil of P. corylifolia could be used as environmentally sound larvicidal and adulticidal agent for mosquito control.

    The leaf of Psidium guajava Linn. (family, Myrtaceae) is used traditionally in African folk medicine to manage, control, and/or treat a plethora of human ailments, including diabetes mellitus and hypertension. In order to scientifically appraise some of the anecdotal, folkloric, ethnomedical uses of P. guajava Linn., the present study was undertaken to investigate the hypoglycemic and hypotensive effects of P. guajava leaf aqueous extract (PGE, 50-800 mg/kg) in rat experimental paradigms. The hypoglycemic effect of the plant's extract was examined in normal and diabetic rats, using streptozotocin (STZ)-induced diabetes mellitus model. Hypertensive Dahl salt-sensitive rats were used to investigate the hypotensive (antihypertensive) effect of the plant's extract. Chlorpropamide (CPP; 250 mg/kg, p.o.) was used as the reference hypoglycemic agent for comparison. Acute oral administrations of the plant's extract (PGE; 50-800 mg/kg, p.o.) caused dose-related, significant (p < 0.05-0.001) hypoglycemia in normal (normoglycemic) and STZ-treated, diabetic rats. Moreover, acute intravenous administrations of the plant's extract (PGE, 50-800 mg/kg i.v.) produced dose-dependent, significant reductions (p < 0.05-0.001) in systemic arterial blood pressures and heart rates of hypertensive, Dahl salt-sensitive rats. Although the exact mechanisms of action of the plant's extract still remain speculative at present, it is unlikely that the extract causes hypotension in the mammalian experimental animal model used via cholinergic mechanisms, since its cardiodepressant effects are resistant to atropine pretreatment. The numerous tannins, polyphenolic compounds, flavonoids, pentacyclic triterpenoids, guiajaverin, quercetin, and other chemical compounds present in the plant are speculated to account for the observed hypoglycemic and hypotensive effects of the plant's leaf extract. However, the results of this experimental animal study indicate that the leaf aqueous extract of P. guajava

    Ultraviolet light-induced reactive oxygen species (ROS) damage human skin and prematurely cause aging. A growing body of research is focusing on considering plants and plant-derived compounds as anti-photoaging therapeutic material. Pterocarpus santalinus L., as an Indian traditional medicine, possesses antidiabetic, anti-inflammatory and antioxidative effects. Here, we studied the anti-photoaging effects of ethanolic extract of P. santalinus L. heartwood (EPS) on ultraviolet radiation B (UVB)-irradiated normal human dermal fibroblasts (NHDFs). Results showed that EPS significantly inhibited the upregulation of matrix metalloproteinases and IL-6 caused by UVB irradiation, and suppressed UVB-induced phosphorylation of extracellular signal-regulated kinase, Jun N-terminal kinase, and p38, as well as the activation of AP-1 transcription factors. Further study indicated that UVB-induced production of MMP-1 and IL-6 could be inhibit by PD 98059 (an ERK inhibitor) and SP600125 (A JNK inhibitor), implied that EPS inhibited UVB-induced MMP-1 and IL-6 secretion by inactivating MAPK signaling pathway. In addition, EPS possessed an excellent antioxidant activity, which could increase cytoprotective antioxidants such as HO-1, NQ-O1 expression by facilitating the nuclear accumulation of Nrf2. Treatment of NHDFs with EPS also recovered UVB-induced procollagen type I reduction by activating TGF-β/Smad pathway. These findings demonstrated that EPS had a potential effect against UVB-induced skin photoaging. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    In a recent study, various extracts of Pterocarpus angolensis were prepared and tested against bacteria. The acetone extract was found to be the most active against all the bacteria investigated, with minimum inhibitory concentrations varying from 0.0156 mg/ml against Staphylococcus aureus to 2 mg/ml against Enterobacter cloacae. Seven pure compounds were subsequently isolated from the ethanol extract of P. angolensis. Using several chromatographic and spectroscopic methods, the structures of five of these compounds - phthalate and four derivatives of epicatechin [(-)-epicatechin, epicatechin-3-O-galate, epicatechin (4beta-8)-epicatechin (B2), and a hexamer of epicatechin] - were successfully determined. The seven purified compounds were then further tested, in vitro, against Staphylococcus aureus and Entamoeba histolytica, and for their in-vitro cytotoxic activity. Although all seven were active against S. aureus, just one of the purified compounds from P. angolensis and piperitenone, a pure compound isolated from Lippia javanica essential oil, were found to have marked activity against Entamoeba histolytica, with median inhibitory concentrations (IC(50)) of 25 and 100 microg/ml, respectively. The other P. angolensis compounds were either weakly active or showed no activity against the amoebae when tested at concentrations up to 400 microg/ml. All seven compounds isolated from P. angolensis showed less toxicity against cultures of human (HCT-8) cells than piperitenone, with IC(50) of 175-375 microg/ml. The presence of epichatechin and derivatives (with strong antibacterial activities but generally weak activities against Entamoeba histolytica) in the stem bark of P. angolensis has thus been demonstrated. Further investigation of the activities of these compounds and their potential use in the treatment of bacterial diseases appears justified.

    Full Text Available The ethnobotanical information of the plant Durio zibenthinus Linn has been existing for a quite a long time. In India this plant is mainly available for the treatment only from the Nilgiris. Ethnomedical information suggests the proven fertility enhancing activity of the folklore. Hence, it was proposed to carry out the isolation, characterization, screening and documentation of phytoconstituents from the fruits of Durio zibenthinus. An additional advantage in working on this plant is the close proximity with the phytochemical lab, which was thought to cause the least degradation of the biologically active constituents. Durio zibenthinus (Durian fruit is being used by the people world wide for its fertility-enhancing activity. The tribal people who grow and harvest this plant claim that the fruits of Durian increases fertility in human beings because, “it kills the germs in the reproductive organs”. But as per the references available, individual compounds have not been implicated for their antimicrobial activity. So, this work aims to study the phytoconstituents for the antibacterial or antifungal potential, taking the cue from the ethnopharmacological literature. The determination of the biological activities helps in developing these compounds into drugs for further drug development. The compound was isolated from the chloroform extract of the Fruit pulp extract of Durio zibenthinus is 7,8-dimethoxy-13,13-dimethyl-2,13- dihydro-3H-Pyrano[5,6-c]quinolin2-one.The isolated compound showed significant antibacterial as well as antifungal activity against the microorganisms tested.

    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.

    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.

    During the screening of endophytes obtained from Glycyrrhiza glabra Linn., the extract from a fungal culture designated as GG1F1 showed significant antimicrobial activity. The fungus was identified as a species of the genus Phoma and was most closely related to Phoma cucurbitacearum. The chemical investigation of the GG1F1 extract led to the isolation and characterization of two thiodiketopiperazine derivatives. Both the compounds inhibited the growth of several bacterial pathogens especially that of Staphylococcus aureus and Streptococcus pyogenes, with IC50 values of less than 10 μM. The compounds strongly inhibited biofilm formation in both the pathogens. In vitro time kill kinetics showed efficient bactericidal activity of these compounds. The compounds were found to act synergistically with streptomycin while producing varying effects in combination with ciprofloxacin and ampicillin. The compounds inhibited bacterial transcription/translation in vitro, and also inhibited staphyloxanthin production in S. aureus. Although similar in structure, they differed significantly in some of their properties, particularly the effect on the expression of pathogenecity related genes in S. aureus at sub-lethal concentrations. Keeping in view the antimicrobial potential of these compounds, it would be needful to scale up the production of these compounds through fermentation technology and further explore their potential as antibiotics using in vivo models.

    Full Text Available The present study was carried out with the water-soluble portion of the ethanol extracts of flowers, barks, seeds and leaves of Nyctanthes arbortristis Linn. to confirm their CNS depressant activity. The ethanol extracts of the plant parts were obtained by soxhlet extraction. After performing the gross behavioral study, the CNS depressant activity was evaluated by observing the prolongation of sleeping time induced by pentobarbital sodium in mice. Attempts have been made to explore the possible mechanism behind this activity by determining their effect on brain monoamine neurotransmitters like dopamine and serotonin. The gross behavioral study showed that ethanol extracts of the leaves, flowers and seeds possess significant CNS depressant activity. The leaves, flowers, seeds and barks (600 mg/kg showed significant and dose-dependent prolongation of onset and duration of sleep and so found to cause decrease dopamine and increase serotonin level. From which it can be concluded that the CNS depressant activity of the ethanol extracts of seeds, leaves and flowers may be due to the decrease in dopamine and increase in serotonin level.

Oil prepared with the juice of leaves of Vitex-negundo is reported to have very useful medicinal properties like wonderful cures of sloughing wounds and ulcers. In Ayurveda; roots of Vitex negundo is reported to have anti-flatulent properties. Philippines peoples used to make tea from fruits of this plant, which was considered very useful in relieving stomach gas which, we refer to flatulence. Here we studied the anti flatulent activity of different essential oils and extracts of Vitex negundo Linn. The standard drug used was simethicone (10 mg/10 g of flatulent diet, p.o., which inhibited gas production up to 90 % as compared to control. Addition of test drugs (essential oils/ethanolic extracts to the chickpea diet (5 % decreased the amount of gas production significantly up to 69% by root and leaves extracts while dry fruit oil inhibited gas formation to 81%. The anti-flatulent activity in this plant may due to combined effect of flavonoids and triterpenoids constituents. As the safety evaluation study indicates that Vitex negundo is well tolerated at very high doses without any toxic effects. Thus, Vitex negundo has a high potential for the development of modern medicine for the treatment of various diseases.

    The antioxidant activity potential of three different plant extracts was investigated against superoxide anion radical while employing cyclic voltammetry technique. The plants Berberis lyceum Royle, Morus nigra Linn and Zanthoxylum armatum were selected because of their potential use in the traditional medicine. The voltammetric response of the electrochemically generated superoxide anion radial in DMSO was monitored in the absence and presence of the plat extracts. The decrease in the current was interpreted in terms of antiradical activity of the added extract. The thermodynamic feasibility of the radical scavenging by extracts was accounted in terms of antioxidant activity coefficient (K(ao)) and standard Gibbs free energy (ΔG(o)). The values of K(ao) and ΔG(o) ranged from 1.0 x 102 to 57 x 102 L(-1) and -18 to -27 kJmol(-1), respectively. The possible mechanism of the antioxidant reaction was regarded as E(r)C(i) mechanism i.e. reversible electron transfer followed by hydrogen atom transfer- an irreversible chemical reaction.

    Bhallataka (Semecarpus anacardium Linn.; Ancardiaceae) is mentioned under Upavisha group in Ayurvedic classics and it is described as a poisonous medicinal plant in Drugs and Cosmetics Act (India), 1940. Fruit of Bhallataka is used either as a single drug or as an ingredient in many compound formulations of Indian systems of medicine to cure many diseases. Tarry oil present in the pericarp of the fruit causes blisters on contact. The major constituent of the tarry oil is anacardic acid and bhilawanol, a mixture of 3-n-pentadec(en)yl catechols. Bhilawanol A and B are known as Urushiols, and also, anacardic acid is closely related to Urushiol. Urushiol-induced contact dermatitis is the medical name given to allergic rashes produced by the oil Urushiol. This paper deals with five case reports of contact dermatitis caused during different stages of Shodhana (purificatory measures) of Bhallataka fruit due to improper handling of the utensils and disposal of media used in Shodhana procedure and their Ayurvedic management. To combat these clinical conditions, the affected persons were advised external application with pounded Nimba (Azadirachta indica A.

    Full Text Available Antibiotics have been used in non-therapeutic fashion as growth promoter for about 50 years in many parts of the world. It has been proven that supplementation of antibiotics in the diets reduces morbidity and mortality, as well as improve feed efficiency and overall growth performance of broiler chickens. However, the routine use of these antimicrobial growth promoters (AGPs is being curtailed in view of threat to public health occurring through microflora that are developing resistance to antibiotics. This risk has driven European Union and other countries to withdraw authorization of in-feed antibiotics since 1997. Removal of AGPs resulted in substantial increase infections in poultry. As a consequence, the poultry industry needs to find alternatives to antibiotics in order to stem the effects of infection. One comparable alternative is natural sources of herbs and medicinal plants, which later known as phytobiotics. For the last 15 years, these alternatives have been increasingly claimed to increase enteric health, stimulate digestive system, and enhance growth performance. It was reported that turmeric (Curcuma longa Linn. belongs to such class of medicinal plant and may be an alternative to antibiotics in poultry production. In this review, the responses of poultry to diets supplemented with turmeric on growth performance, egg production, health status, and carcass characteristic were briefly discussed.

    Full Text Available The use of compounds which can selectively protect normal tissues against radiation injury is of immense use because in addition to it protecting the normal tissue, will also permits use of higher doses of radiation to obtain better cancer control and possible cure. However, most of the radio protective compounds investigated possess inadequate clinical application principally due to their inherent systemic toxicity at their optimal protective concentrations. Plants commonly used as medicinal and dietary agents have recently been the focus of attention and studies have shown that Ocimum sanctum Linn. commonly known as the Holy Basil and its water soluble flavonoids, orientin and vicenin protects experimental animals against the radiation-induced sickness and mortality at nontoxic concentrations. Studies with tumor bearing mice have also shown that both Tulsi extract and its flavonoids selectively protect the normal tissues against the tumoricidal effects of radiation. Preclinical studies have also shown that the aqueous extract of the Tulsi leaves; its flavanoids orientin and vicenin, and eugenol, the principal nonpolar constituent present in Tulsi prevent radiation-induced clastogenesis. Mechanistic studies have indicated that free radical scavenging, antioxidant, metal chelating and anti-inflammatory effects may contribute toward the observed protection. In addition, clinical studies with a small number of patients have shown that Tulsi was effective as a radio protective agent. This review summarizes the results related to the radio protective properties of Tulsi and its phytochemicals and also emphasizes the aspects that warrant future research to establish its use as a radio protective agent.

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

    Full Text Available Dioscorea bulbifera Linn. is a unique wild yam able to thrive in a wide range of ecological zones. Mopho-molecular studies were carried out with a view to relating the observed morphological variation to its genetics. For morphometric study,30 representative herbarium vouchers  were studied while recently expanded leaf tissue samples of 34 accessions of five natural populations were submitted for genomic DNA using sixteen SSR markers. Bulbil size and shape, petiole length, leaf colour and shape varied among populations. A low level of genetic variability characterized the two geographically closest of the five populations (with P=15.15 and 6.06%,; H=0.0646 and 0.0251 while the other populations showed higher values (P varied from 66.6 and 84.85%; H varied from 0.1992 and 0.1992. That the highest value of genetic distance (0.1964 occurred between Iwo and Polytechnic populations was unexpected. The highest value (0.9869 of genetic identity occurred between the Polytechnic and Pebble Road populations as expected. Clustering typically occurred at lower distance scale reflecting the proximity of their genetic distances and therefore low divergence. Conclusively, the use of microsatellite markers allowed the identification of genetic variability among the natural populations of D. bulbifera.

    Full Text Available The crude extracts obtained from the aerial parts of Artemisia annua Linn. (Asteraceae were investigated for their antibacterial activity by using agar well diffusion assays against five Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis, Bacillus pumilus, Bacillus cereus, and Micrococcus luteus and three Gram-negative bacteria (Escherichia coli, Salmonella typhi, and Pseudomonas aeruginosa. Of the various extracts, the methanol extract showed the strongest activity against most bacteria used in this study. The most sensitive organism to the extracts was M. luteus. The minimum inhibitory concentration (MIC values were determined by the tube dilution method. The results showed that S. aureus required ~0.25 mg/mL of the methanol extract for inhibition. The HPTLC fingerprint of the methanol extract after derivatization with anisaldehyde sulphuric acid reagent showed a maximum number of separated components. TLC bioautography of the methanol extract showed that the area of inhibition around compounds differentiated at R f = 0.32, R f = 0.42, R f = 0.46, R f = 0.77, and R f = 0.87 against S. aureus. This is the first report of the antibacterial activity of A. annua against food-borne bacteria. The results indicated that aerial parts of A. annua might be potential sources of new antibacterial agents.

    Bacoside-A (B-A) was evaluated for its hepatoprotective activity against d-GalN induced liver injury in rats. B-A is a major constituent isolated from the plant Bacopa monniera Linn. B-A (10mg/kg of body weight) was administered orally once daily for 21 days and then d-GalN (300 mg/kg of body weight) was injected on 21st day after final administration of B-A. B-A reduces the elevated levels of serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (gamma-GT), lactate dehydrogenase (LDH), 5'nucleotidase (5'ND). In addition B-A also significantly restored towards normalization of the decreased levels of Vit-C, and Vit-E induced by d-GalN both in liver and plasma. These results suggest that B-A has hepatoprotective effect against d-GalN induced hepatotoxicity in rats.

    The study was to investigate and compare the effects of the Bacopa monniera Linn. extract and bacoside A on the ICR mice immune system in vitro. Splenocyte proliferation without or with mitogen (lipopolysaccharide, pokeweed mitogen, phytohaemagglutinin and concanavalin A) and phagocytic activity were assayed. The results showed that B. monniera extract at 0.001-1 mg/mL slightly suppressed splenocyte proliferation (SI 0.7) and decreased T-lymphocyte proliferation (SI 0.4) at 0.001 and 0.1 mg/mL with concanavalin A. Bacoside A at 0.001 mg/mL gave the highest splenocyte proliferation (SI 1.5) and strongly increased T-lymphocyte proliferation (SI 2.0) at 0.1 mg/mL with concanavalin A. Thus, it is possible to attribute the effect of B. monniera extract on splenocyte proliferation to the presence of bacoside A with other combined components. However, only B. monniera extract at 10 mg/mL produced a slight increase in lysosomal enzyme activity (PI 1.2), indicating a weak effect on phagocytic activation. It might be concluded that B. monniera manifests various effects on the murine immune system depending on the immune cell types, in accordance with its folklore uses. New assays are being carried out to study its mechanisms and to further investigate its applications in the treatment of human immune mediated diseases.

    Full Text Available Thunbergia laurifolia (linn., TL, a natural phenolic compound, has been reported to have many benefits and medicinal properties. The current study ascertains the total phenolic content present in TL aqueous leaf extract and also examines the antioxidant ability of the extract in preserving acetylcholinesterase (AChE activity of mice exposed to lead in vivo and in vitro model. Mice were given lead acetate (Pb in drinking water (1 g/L together with TL 100 and 200 mg/kg/day. The result showed that Pb induced AChE dysfunction in both in vitro and in vivo studies. TL significantly prevented Pb induced neurotoxicity in a dose-dependent manner which was indicated by comparatively better performance of TL treated mice in Morris Water Maze Swimming Test and increased AChE activity in the tissue sample collected from the brains of these mice. TL also exhibited the greatest amount of phenolic content, which has a significant positive correlation with its antioxidant capacity (P<0.05. Taken together, these data suggested that the total phenolic compounds in TL could exhibit antioxidant and in part neuroprotective properties. It may play a potential treatment strategy for Pb contamination.

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

    2012-01-01

    Full Text Available The anti-inflammatory, analgesic and ulcerogenic activity of extract of leaves of Vigna Mungo linn. (Leguminosae were investigated as well as the mechanisms of action. The extract significantly (P<0.05 inhibited the formation of paw edema induced by    carrageenan in rat and increased reaction latency to thermal pain in rat in a dose-dependent manner. The extract caused a significant (P<0.05 dose-dependent ulceration of rat gastric mucosa and concentration-dependent inhibition of hypotonicity-induced haemolysis of red blood cell. Also the extract significantly (P<0.05 inhibited the activates of the phospholipase A2 and prostaglandine synthesis in a concentration related manner. These suggest that the leaves posses anti-inflammatory, analgesic and ulcerogenic activities mediated through sequential inhibition of the enzymes responsible for prostaglandine synthesis from arachidonic acid. Phytochemical analysis of the extract revealed the presence of glycoside, tannins, alkaloid, flavonoids and Saponins. Acute toxicity studies established an oral LD50 greater than 3000 mg/kg.

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

    The study describes the scope of clonal propagation of guava (Psidium guajava Linn.) by stem cutting collected from mature stockplants. Cuttings were treated with 0, 0.2%, 0.4% and 0.8% IBA solution and rooted in the non-mist propagator. Rooted cuttings were allowed to grow in the polybags filled with soil and cow-dung mixed in the ratio of 3:1 (by volume) for three months to assess the steckling capacity and initial growth performance. The study reveals that the species is amenable for clonal propagation by mature stem cutting. The highest rooting percentage (60%) was observed in the cuttings treated with 0.4% IBA solution followed by 0.2% IBA and the lowest was in controlled cuttings. The maximum number of primary root (32.7) was developed in the cuttings treated with 0.8% IBA solution followed by 0.4% IBA and the lowest was in the cuttings without IBA treatment. The highest survival percentage (70.9) was observed in the cuttings rooted with 0.4% IBA treatment and the lowest (58.3) was in the cuttings without any treatment. However, there was no significant variation in height growth of cutlings due to IBA treatments in rooting.

    Permafrost is one of six cryospheric indicators of global climate change. As permafrost contains various forms of ground ice, thawing, degradation and speed up of particularly ice-rich periglacial landforms can lead to substantial landscape change and development. This has geomorphological, biological and socio-economical impacts, with changes in the water balance, increase in greenhouse gas emissivity, changes in flora and fauna and impacts on infrastructure. The present scientific challenge is to combine detailed site/point scale geomorphological field process observations with remote sensing data covering at landscape scale. We apply a multi-temporal satellite radar interferometric (InSAR) method to data obtained using the TerraSAR-X satellite. TerraSAR-X has a high spatial resolution and with 11 days repeat cycle, it is well suited to detect seasonal permafrost deformation. To test the usability of X-band InSAR data, we compare hourly field measurements between 2008-2011 of solifluction ground deformation at Kapp Linné, central Svalbard, with InSAR deformation time-series. We show that InSAR is able to pick up the seasonal deformation patterns of frost heave, ground settlement and associated solifluction as well as the interannual downslope movement. These results are a promising first step towards successful upscaling periglacial field point measurements to landscape scale, enabling observations of periglacial processes in larger parts of the permafrost landscapes.

    Snake bite has been regarded as an important health problem in Myanmar since early 1960's. In the recent years, there has been growing interest in alternative therapies and therapeutic use of natural products, especially those derive from plants. In Myanmar and Indian traditional medicine, various plants have used as a remedy for treating snake bite. The present study was carried out to evaluate the effects of alcohol extract of Tamarind (Tamarindus indica Linn.) seed on some biologic properties of Russell's viper (Daboia russelli siamensis) venom (RVV). The Phospholipase A2 (PLA2) enzyme, coagulase enzyme and caseinolytic enzyme activities of Russell's viper venom (RVV) were reduced when mixed and incubated with the extract. When the RVV and the different amount of extracts were preincubated and injected intramuscularly into mice, all of them survived, but all the mice in the control group died. On the other hand, when RVV were injected first followed by the extract into mice, all of them died. If the extract was injected near the site where Russell's viper venom was injected, all the mice survived for more than 24 hours and the survival time prolonged but they all died within 96 hours. In conclusion, according to the results obtained, the extract neutralizes some biologic properties of the Russell's viper venom and prolonged the survival time if the extract was injected near the site where the Russell's viper venom was injected.

    Colocasia esculenta Linn (CE) is traditionally used for the treatment of various ailments such as high blood pressure, rheumatic pain, pulmonary congestion, etc. Hence in present study, the effect of aqueous extract of CE leaves (AECE) was evaluated for antihypertensive and acute diuretic activity in rats. Preliminary phytochemical evaluation revealed the presence of carbohydrate, saponins, tannins, and flavonoids in AECE. The animals did not show any sign of toxicity and mortality after the administration of AECE 2000 mg/Kg in acute oral toxicity study. The administration of AECE (100, 200, and 400 mg/Kg/day, p.o.) for six weeks and AECE (10, 20, and 40 mg/Kg, IV) on the day of experiment in renal artery-occluded hypertensive rats and AECE (20 and 40 mg/Kg, IV) in noradrenalin-induced hypertension in rats produced significant (p < 0.05) anti-hypertensive effects. AECE (400 mg/Kg, p.o.) showed positive diuretic activity at 5 h. AECE (200 and 400 mg/Kg, p.o.) significantly increased sodium and chloride content of urine in 5 h and 24 h and additionally potassium in 24 h urine. Hence, the results of the present study revealed the antihypertensive and weak diuretic activity of AECE. These effects may be attributed due to the ACE inhibitory, vasodilatory, β-blocking, and/ or Ca(2+) channel blocking activities, which were reported for the phytoconstitunts, specifically flavonoids such as vitexin, isovitexin, orientin, and isoorientin present in the leaves of CE.

    In traditional medicine, Tridax procumbens Linn. is used in the treatment of injuries and wounds. The bacterial endophytes (BEs) of medicinal plants could produce medicinally important metabolites found in their hosts; and hence, the involvement of BEs in conferring wound healing properties to T. Procumbens cannot be ruled out. But, we do not know which types of BEs are associated with T. Procumbens. The objective of this study was to investigate the fast growing and cultivable BEs associated with T. procumbens. Leaves and stems of healthy T. Procumbens plants were collected and cultivable BEs were isolated from surface-sterilized leaf and stem tissue samples using Luria-Bertani (LB) agar (medium) at standard conditions. A polymerase chain reaction was employed to amplify 16S rRNA coding gene fragments from the isolates. Cultivable endophytic bacterial isolates (EBIs) were identified using 16S rRNA gene nucleotide sequence similarity based method of bacterial identification. Altogether, 50 culturable EBIs were isolated. 16S rRNA gene nucleotide sequences analysis using the Basic Local Alignment Search Tool (BLAST) revealed identities of the EBIs. Analysis reveals that cultivable Bacillus spp., Cronobacter sakazakii, Enterobacter spp., Lysinibacillus sphaericus, Pantoea spp., Pseudomonas spp. and Terribacillus saccharophilus are associated with T. Procumbens. Based on the results, we conclude that 24 different types of culturable BEs are associated with traditionally used medicinal plant, T. Procumbens, and require further study.

    Objective: To assess the antifertility activity of ethanolic extract of Caesalpinia pulcherrima Linn (C. pulcherrima) leaves in albino female mice. Methods: Acute toxicity study of the extract was carried out in adult albino mice. The antifertility activity of the extract at dose levels (200 and 400 mg/kg, orally) was evaluated in two experimental animal models i.e. antiimplantation and esterogenic/antiestrogenic activity in female mice by observing no. of implants, estrus cycle, vaginal cornification, uertus weight and cholesterol content. Results: The extract was found to be safe up to a dose of 4 000 mg/kg body weight when administered orally. A good antiimplantation (66.66 %) activity in female mice was observed at the tested dose levels (200 and 400 mg/kg, orally). The extract further showed more significant (P<0.05) increase in uterine weight and cholesterol content in immature mice. Simultaneous administration of extract alongwith ethinyl estradiol showed significant estrogenic activity. Conclusion: The results suggest that ethanolic extract of C. pulcherrima leaves possess significant antifertility activity, therefore, justifying the traditional use of this plant in fertility regulation.

    Polymerase chain reaction (PCR) amplification of a partial fragment of the sex determining region Y (SRY) gene was used for sexing a young Linne's two-toed sloth (Choloepus didactylus), a species in which gender determination from the external genitalia is difficult. DNA was extracted from hairs of a 5-month-old sloth as well as the dam and sire as external controls. A SRY fragment (216 bases) was PCR-amplified both from the offspring and the sire, but not amplified from the dam. The DNA sequence (166 bases without primers) of the sloth PCR product was determined and compared with SRY sequences of other mammals previously reported. High homology of their nucleotide (74.1-86.8%) and deduced amino acid (63.6-85.5%) sequences indicates that the PCR product of the sloth was amplified from a region of the SRY gene, and that SRY sequences are conserved throughout mammalian orders. From the result the sex of the young sloth was determined as a male. The PCR method using hairs for sexing the sloth provides an advantageous tool for captive propagation plan in zoos. To the authors' knowledge, no report regarding SRY sequences in the order Xenarthra (Edentata) has been published.

    In a preliminary study, we found that the cadmium (Cd) concentrations in shoots of the winter farmland weeds Cardamine hirsuta Linn. and Gnaphalium affine D. Don exceeded the critical value of a Cd-hyperaccumulator (100 mg kg(-1)), indicating that these two farmland weeds might be Cd-hyperaccumulators. In this study, we grew these species in soil containing various concentrations of Cd to further evaluate their Cd accumulation characteristics. The biomasses of C. hirsuta and G. affine decreased with increasing Cd concentrations in the soil, while the root/shoot ratio and the Cd concentrations in shoot tissues increased. The Cd concentrations in shoots of C. hirsuta and G. affine reached 121.96 and 143.91 mg kg(-1), respectively, at the soil Cd concentration of 50 mg kg(-1). Both of these concentrations exceeded the critical value of a Cd-hyperaccumulator (100 mg kg(-1)). The shoot bioconcentration factors of C. hirsuta and G. affine were greater than 1. The translocation factor of C. hirsuta was less than 1 and that of G. affine was greater than 1. These findings indicated that C. hirsuta is a Cd-accumulator and G. affine is Cd-hyperaccumulator. Both plants are distributed widely in the field, and they could be used to remediate Cd-contaminated farmland soil in winter.

    Full Text Available Ethnobotany is a multidisciplinary science defined as the interaction between plants and people. On the basis of ethnomedicinal use, antipyretic activity of petroleum ether, ethyl acetate, chloroform, methanol extract of Cassia fistula Linn (Fabaceae bark has been investigated in albino rats. Normal body temperature is regulated by a centre in the hypothalamus that ensures a balance between heat loss and production. Fever occurs when there is a disturbance of this hypothalamic ‘thermostat’, which leads to the set-point of body temperature being raised. Once there has been a return to the normal set-point, temperature regulating mechanism (dilatation of superficial blood vessels, sweating etc. operates to reduce temperature. The study was carried out by using dose of 300 mg/kg orally. Experimental results exhibited that petroleum ether, ethyl acetate, chloroform, methanol extract of Cassia fistula bark, possess a significant antipyretic effect. After inducing 15% w/v suspension of yeast (1ml /100gm Body weight, temperature of experimental animal was increased. Then different extracts of the drug was induced into albino rats, which shows significant results. It was observed that methanol extract at a dose of 300 mg / kg body weight showed maximum antipyretic activity amongst other extracts which is statistically significant as the value of p<0.05.
