2-O-(β-D-Glucopyranosyl)-L-ascorbic acid, a natural β-glycoside with ascorbic acid moiety present in Lycium barbarum, and its two analogues were chemically synthesized. Their inhibitory effect on yeast α-glucosidase and α-amylase were investigated with commercially available acarbose as positive control. The biological assays demonstrated the distinct inhibitory effect of these compounds on α-glucosidase activity and weak inhibitory activity against pancreatic α-amylase. The kinetic study indicated that these compounds were competitive inhibitors. These results imply that these three β-glycosides have the potential to be developed as α-glucosidase inhibitors.

Key words: 2-O-(β-D-glucopyranosyl)-L-ascorbic acid, analogue, synthesis, α-glucosidase, α-amylase, inhibitor
