Churna by α-amylase
inhibition was carried out by starch iodine method, initrosalicylic acid method (DNSA)
and effect on normal rats blood sugar level was studied. Nisamalaki Churna
shows potent α-amylase inhibition IC50 89.44 μg/mL by starch iodine method
and IC50100.0
μg/mL by DNS method. Nisamalaki Churna showed potent decrease in blood glucose
