Inhibitory effect of Gymnema Montanum leaves on α-glucosidase activity and α-amylase activity and their relationship with polyphenolic content

The present study was attempted to investigate the effect of G. montanum leaf extract on inhibition of α-glucosidase and α-amylase activity. The ethanol extract of G. montanum (GLEt) at various concentrations (1–10 μg/ml) was tested for its inhibition pattern against α-glucosidase and α-amylase activity in vitro and compared with the commercially available α-glucosidase inhibitor, acarbose. The GLEt showed competitive inhibition against yeast...
