ABSTRACT Diabetes mellitus is an endocrinal disorder associated with depleted insulin secretions, damaged pancreatic β- cells with altered carbohydrate, lipid and protein metabolism. It is the most common serious metabolic disorder and is considered to be one of the five leading causes of death in the world. Costus igneus, commonly known as insulin plant in India, belongs to the family Costaceae. The aim of the study is to compare inhibitory effect of aqueous leaf extract of Costus igneus and the anti diabetic drug acarbose on salivary amylase, goat pancreatic amylase and commercial porcine pancreatic amylase activities. The results showed a significant inhibitory effect of Costus igneus on amylase activities. Preliminary phytochemical screening of ethanol, aqueous and chloroform extracts revealed the presence of carbohydrates, cardiac glycosides, proteins, flavonoids, saponin and tannins. The results of TLC analysis reported the presence of the flavonoid in Costus igneus leaf extract.
