A complete documentation of the ethno-biological information presently existing among the diverse communities is needed at an earliest so as to restore the traditional medicinal knowledge. Research to find out scientific evidence for claims by tribal healers on Indian herbs has been intensified as being evidenced from many cited literatures. Once these local ethno medical preparations are scientifically evaluated and disseminated properly, people will be better informed regarding efficacious drug treatment and improved health status. Hence, the plant, Mimosa pudica Linn. was selected for the present study based on its medicinal use in the locality. Successive solvent extraction of the root powder of M. pudica was carried out as per the standard procedure using various solvents like, petroleum ether (40o-60oC), ethyl acetate and methanol. Preliminary phytochemical analysis, isolation of metabolites and antimicrobial activities of the extracts as well as the first time reported isolates were carried out. Preliminary phytochemical studies of vaious solvent extracts revealed presence of many biologically important secondary metabolites, such as, alkaloids, steroids, phenolic compounds, tannins,...

Aim: To assess the effect of vanadium compounds on glycemic control in diabetic rats. Methods: Eligible studies were identified by searching two databases; one search engine was also used for search of articles from different data bases using standardized terms and Boolean logic. Statistical analysis was performed with Meta Analyst software. Results: 56 relevant studies were found but only 8 studies met the inclusion criteria for this meta-analysis. Meta-analysis was done for blood glucose level from a pooled sample of 84 vanadium treated and 80 control diabetic rats. The analysis generated a combined standardized mean difference (Std. mean difference) of -5.21 and p< 0.00001 for blood glucose level. Additionally, all the included studies lay in favor of vanadium treatment. The meta-analysis for average weight and plasma insulin level did not show significant variation between vanadium treated and control diabetic rats. Conclusion: This meta-analysis reaffirmed that, vanadium compounds are able to reduce significantly blood glucose level and other base line measures like food intake and fluid intake without affecting plasma...

Antioxidants have important role in prevention and treatment of disorders and plants are considered as rich sources of radical scavenging compounds. Nowadays, many herbs are used in dried form which is possible to affect their antioxidant activity. In the present investigation, the effects of different drying methods on the antioxidant capacity and total phenolics content of some culinary plant species have been studied. Leaves of Mentha piperita, Mentha spicata, Thymus vulgaris and Anethum graveolense were dried in sun, shade, oven and microwave and extracted with methanol. Antioxidant activity of each extract was determined by DPPH free radicals and total phenolics content was measured by folin cio-calteus reagent. The results revealed that drying process reduced the antioxidant activity of Anethum graveolense whereas sun-drying and shade-drying increased the antioxidant activity of Mentha piperita, Mentha spicata and Thymus vulgaris (Lamiaceae). During sun-drying and shade-drying, total phenolics content increased for the three plants of Lamiaceae while oven- and microwave-drying reduced the phenolics content. Drying also declined the phenolics content of Anethum graveolense which...

The objective of this study was to develop simple, precise, accurate, reproducible and economical vireodt’s method for simultaneous estimation of mesalamine (MSM) and prednisolone (PRD) in combined oral dosage form. The method involved measurement of absorbance at two wavelengths, 332nm and 246nm, λmax of MSM and PRD, respectively in phosphate buffer (pH 7.4) with dimethyl formamide (DMF) as cosolvent. The linearity was obtained in the concentration range of 5-50 µg/ml and 2-20 µg/ml for MSM and PRD, respectively. The average percent recovery of MSM and PRD was found to be 99.19+0.78% and 99.71+0.82%, respectively. The accuracy and precision were determined and recovery studies confirmed the accuracy of the developed method that was carried out following the International Conference on Harmonization (ICH) guidelines. The recovery study was carried out by standard addition method. The proposed method was found to be rapid, specific, precise, accurate, and reproducible and can be successfully applied for the routine analysis of MSM and PRD in pharmaceutical dosage...

The course on “Herbal Medicines, Nutraceuticals and Dietary Supplements” has been implemented among the new courses within the 2007 curriculum of the Pharmacy Program, School of Food, Biochemical and Pharmaceutical Sciences at the Catholic University of Cuyo, located in San Juan Province, Argentina. The main objective of the course is to provide students with the necessary tools to acquire knowledge on new concepts of nutritional therapies, functional foods and dietary supplements. All of which are meant to revert or prevent unfavorable health conditions. This paper describes the methodology used in the development of the course, the minimum contents exposed, experience and teacher evaluation during the years 2009 and...
