Objective: To evaluate the analgesic and anti-inflammatory effects of the methanolic extract of the Jatropha curcas (MEJC) belonging to the family Euphorbiaceae. Materials and Methods: Phytochemical screening was done by standard procedures. Acute toxicity studies were done by using female albino mice weighing 23-35 gm as per OECD 425 guidelines. In the hot plate models for analgesic activity, the oral administration of J. curcas extract at the three different doses of MEJC like (100, 200, 400 mg/kg) and the reference drug diclofenac sodium (25 mg/kg) were administered. The control group was taken using normal saline 0.9% NaCl solution. While in the carrageenan-induced paw edema models, the same dosage regimen as per the analgesic activity were followed but the standard drug dose of aspirin is 150 mg/kg. Results: Phytochemical screening revealed the presence of flavonoids, steroids, alkaloids, tannins, carbohydrates, cardiac glycosides. The extract was found to be non-toxic up to the dose of 2000 mg/kg after the acute toxicity test. In analgesic all the three doses of MEJC i.e. 100mg/kg...

The present investigation deals with fast disintegrating tablets of the model drug (Telmisartan) and to determine the influence of the excipients on physical properties of tablets. Employing a Box Behnken design, concentration of co-processed superdisintegrants (Crosspovidone: sodium starch glycolate) (X1), the concentration of meglumine (X2) and concentration of sodium lauryl sulfate (X3), selected as independent variables whereas disintegration time (Y1) selected as the dependent variable. All formulations were evaluated for pre-compression and post-compression parameters. Mathematical equations and response surface plots were used to relate the dependent and independent variables. The regression equation generated for disintegration time (DT) of Telmisartan tablets was Y1=30.25-1.6887A-1.2175B +2.7437C +0.1675AB +2.02AC+3.007BC-2.6752A2-3.62B2+ 0.0425C2. The statistical validity of the polynomial was established, and optimized formulation factors were selected by feasibility and grid search. Validation of the optimization study with 13 confirmatory runs indicated a high degree of prognostic ability of response surface...

Indian medicinal plants are considered as a vast source of several pharmacologically active principles and compounds, which are commonly used in home remedies against multiple ailments. Plant secondary metabolites such as alkaloids, tannins, steroids, terpenoids, coumarins and phenolic compounds and their semi-synthetic derivatives continue to play an important role in anticancer drug therapy. Molecular docking is a computational technique that aims to predict how a particular small molecule will stably bind to a target protein. It is an important component of many drug discovery projects when the structure of the protein is available. Although it is primarily used as a virtual screening tool, and subsequently for lead optimization purposes, there are also applications in target identification. To characterize the phytochemical constituents and anti-tumorigenic efficacy of methanolic extract of Ficus racemosa bark against cancer target proteins using in-silico Glide docking and QikProp panel. The results showed that the presence of phytochemical constituent’s namely, flavonoids, steroids, saponins, glycoside, tannins, phenolics, fixed oils and fats and the total 24 phytochemical constituents present...

Medicinal plants are essential in our balanced life diet and are in demand in allopathic and herbal medicine. The present study was aimed to evaluate the phytochemical, antioxidant and antimicrobial activities of Phyllanthus emblica (Euphorbiaceae), Averrhoa bilimbi (Oxalidaceae) and Phyllanthus acidus (Euphorbiaceae) fruits. The preliminary phytochemical analysis was carried out using standard methods. Total phenolic, flavonoid, protein, vitamin-C and tannin content were analyzed. Antioxidant and antibacterial activity was assessed by DPPH and agar well diffusion method. Phytochemical screening revealed the presence of alkaloids, flavonoids, glycoside, phenols, proteins, and amino acids, steroids, saponins, terpenoids, tannins, resins and emodols in different fruit extracts. The phenolics, protein and vitamin C content were higher in Phyllanthus emblica fruits. While flavonoids and tannin content was higher in Averrhoa bilimbi fruits. The free radical scavenging activity was significantly higher in Phyllanthus emblica fruits. Maximum inhibition of antibacterial activity was noticed in Phyllanthus emblica against Bacillus subtilis followed by Klebsiella pneumoniae, Staphylococcus aureus, and Escherichia coli respectively. In conclusion, our studies provide evidence that fruit extracts...

Diabetes mellitus is one of the most common endocrine disorder which causes microvascular and macrovascular complications. Herbal medicines derived from plant extracts are used to treat various diseases because of its fewer side effects. The present investigation includes a screening of phytochemicals and evaluation of the in-vitro and in-vivo anti-diabetic activity of Hellenia speciosa leaves extract. The leaf extract was screened for various phytochemicals and then subjected to in-vitro anti-diabetic study using alpha-amylase and alpha-glucosidase enzyme. Inhibition of carbohydrate digestive enzymes amylase and glucosidase can effectively decrease the postprandial increase of glucose level. This is an important strategy in the management of diabetes. This was followed by the in-vivo study to evaluate the anti-diabetic effect of Hellenia speciosa leaves in normal and alloxan induced diabetic rats. The oral administration of crude leaf extract in diabetic rats for 28 days at a dosage of 300 mg/kg body weight exhibited a significant reduction (P<0.05) in fasting blood glucose level and remarkable increases in serum insulin level. The action of Hellenia speciosa...
