Objective: To investigate the effect of epigallocatechin-3-gallate (EGCG) on the activity of alpha-glucosidase derived from bakers' yeast and small intestinal mucosa of Wistar rats, in order to establish an evaluation system for the activity of alpha-glucosidase inhibitor.
Methods: alpha-glucosidase was prepared from the bakers' yeast and the small intestinal mucosa of Wistar rats. The inhibitory activity of EGCG on alpha-glucosidase was based on the concentration of glucose in the reaction system.
Results: EGCG was shown to be an alpha-glucosidase inhibitor. IC50 was 0.150 mg/ml and 0.837 mg/ml for alpha-glucosidase derived from bakers' yeast and small intestinal mucosa respectively.
Conclusion: The establishment of an in vitro evaluation system for AGI activity is conductive for screening alpha-glucosidase inhibitory substance. The AGI activity of EGCG is strong in vitro.
