Pongamia Pinnata (Stem bark) and Glycine max (fruits) were selected for evaluation of antidiabetic activity. Extracts were prepared by cold maceration method. Maximum antihyperglycaemic activity was observed in petroleum ether extract of Pongamia Pinnata (Called as PPSB-PEE). 11 compounds were isolated by column chromatography. Compound B2 was most promising antihyperglycaemic activity hence further characterized by physical and chemical properties. B2 was pure compounds namely cycloart-23-ene-3, 25 diol. B2 was further carried out for antidiabetic activity of streptozotocin-nicotinamide...
