Abstract : Alpha- amylase and alpha- glucosidase are played a important role in the carbohydrate digestion. These enzymes digest the carbohydrates from mouth onwards. The inhibition of this enzyme may reduces the glucose concentration in blood stream. The recent researches are find the therapeutic approaches to reduces the glucose level in blood by the inhibition of this enzymes in the in vitro analysis. This can be a major strategy for the management of blood glucose level in the body. The aim of the present study was to investigate the phytochemical analysis of various extract and find out the in vitro anti-diabetic activity of Syzygium cumini seeds. The result proves that the presence of phytoconstituents could be responsible for the medicinal properties of this plant including diabetes and the extract exhibit the dose-dependent action by increasing the inhibitory effect on the alpha-amylase enzyme and alpha- glucosidase enzyme.
