An improved process for the production of aqueous dry extract of Vijaysar (Pterocarpus marsupium) has been developed on pilot scale (100 kg hatch capacity). The new process takes only 18 h as compared to 72 h of the conventional process. The energy consumed is 1/3 of the old process and yield of Vijaysar using the new process improved by 2 to 2.5%. At the same time no change was observed in the quality of the final product with respect to hypoglycaemic activity. HPLC profile and other standard quality parameters.
