Abstract

The present study was to fabricate and evaluate oral anti- diabetic sustained release herbal tablets by direct compression method with dry extracts of Costus Pictus., Trigonella Foenum- Graecum and Abelmoschus Esculentus were used as the polymers and binding agent respectively in the preparation of Costus Pictus sustained release tablets.Costus Pictus were subjected for isolation and identification of active compound. The isolated compound were identified by UV, IR, Mass and NMR spectroscopy and the compound identified as the β- Amyrin of triterpenoids, which may be responsible for the anti diabetic activity. Physico chemical properties of dried powdered blend were studied. Prepared tablets were evaluated for thickness, hardness, friability, uniformity of weight, swelling behavior and release ate characteristic were studied. The extract of Trigonella Foenum- Graecum and Abelmoschus Esculentus showed sustained release of the drug Costus Pictus with the concentration of 15 % of the binder and the polymer. The in-vitro release data was applied to various kinetic models and the optimized formulation (F6) was to follow zero order kinetics. In- vivo studies were done to evaluate anti diabetic activity in rabbits and the formulation F6 was found to be the best among all the formulation. Studies indicated that the extracted drugs is a good pharmaceutical adjuants and possess anti – diabetic activity. Finally it is concluded that the herbal tablets of Costus Pictus has reduced side effects, low cost and improved bio availability of the drug.
