Abstract

Diabetes mellitus is a clinical condition characterized by hyperglycemia in which an elevated amount of glucose circulates in the blood plasma. Alpha amylase inhibitors are used to achieve greater control over hyperglycemia in type 2 diabetes mellitus. The present study intends to screen novel alpha amylase inhibitors from natural sources like lichens in order to minimize the toxicity and side effects of the inhibitors currently used to control hyperglycemia. The aim of this work was to evaluate the in vitro antidiabetic activity of methanol and ethyl acetate extracts of lichens at various concentrations. Two lichens were collected from Mysore district, Karnataka and identified as Flavoparmelia caperata (L.) Ach. and Physcia aipolia (Ehrh. ex Humb.) Furnr. The alpha amylase inhibition assay showed that the methanolic extract of F. caperata had highest inhibition of 49 at 15mg/ml, followed by P. aipolia with 46 inhibition. The results of the work, therefore clearly indicate the potential of these extracts to manage hyperglycemia. Hence lichens could be exploited in the development of active agents in regulating the postprandial glucose level to control diabetes
