This experiment was designed to synthesize 18 kinds of polyhydroxybenzophenones by using Friedel-Crafts reaction, and to measure the inhibitory activity on α-glucosidase with p-nitrophenyl-β-D-galactopyranoside (PNPG) as a substrate. Here, acarbose (IC(50)  = 1674.75 µmol L(-1) ) was used as the reference
