ABSTRACT
Objective To extract ?-glucosidase inhibitors from Potentilla anserina L. Methods Water-decocting method and water-decocting ethanol-precipitation were applied to obtain water extract,sodden ointment and polysaccharides of Potentilla anserina L. The colorimetry of pNPG was used for the determination of the activity of alpha-glucosidase pure enzyme and alpha-glucosidase from isolated small intestines of natural ICR mice. Results The extracts of Potentilla anserina L. had obvious inhibitory effect on the pure enzyme of ?-glucosidase. The water extract and sodden ointment also had inhibitory effect on ?-glucosidase from isolated small intestine in natural ICR mice,the effect being in a dose-dependant manner. Conclusion The extracts of Potentilla anserina L. have the inhibitor-like effect on ?-glucosidase,and the active position is probably in the sodden ointment.
