*3.4. In Vitro Enzyme Inhibition Assay*

The EA extract exhibited α-amylase and α-glucosidase inhibitory activity in a dose-dependent manner. Acarbose was used as a standard. IC50 value of EA extract for α-glucosidase and α-amylase inhibition was found to be 21.17 and 20.46 respectively, whereas that of acarbose was 15.47 and 18.15 μg/mL respectively (Tables 3 and 4).
