title: Purunusides A-C, alpha-glucosidase inhibitory homoisoflavone glucosides from Prunus domestica.
abstract: Purunusides A-C (1-3), new homoisoflavone glucosides together with the known compounds beta-sitosterol (4) and 6,7-methylenedioxy-8-methoxycoumarin (5) have been isolated from n-butanol and ethyl acetate soluble fractions of Prunus domestica. Their structures were assigned on the basis of spectral studies. The compounds 1-3 showed potent inhibitory activity against the enzyme alpha-glucosidase.
