英文摘要: One new resveratrol analogue, 1-(3',4',5'-trimethoxyphenyl)-2-methoxy-2-(4 ''-methoxyphenyl)-ethane-1-ol (1), and two new prenylisoflavones, 4'-hydroxy-5,7-dimethoxy-6-(3-methyl-2-butenyl)-isoflavone (2), and derrubon 5-methyl ether (3), together with 17 known compounds including one new natural product, 5,7-dihydroxy-3-[4'-O-(3-methyl-2-butenyl)-Phenyl]-isoflavone (4), were isolated from the stems of ethnomedicinal plant Derris eriocarpa How. (Leguminosae). Their structures were elucidated based on chemical evidence and spectroscopic techniques including two-dimensional NMR methods. All compounds are reported from this species for the first time. Antimicrobial activities of the new compounds were evaluated. Compound 2 exhibited good inhibitory activities against Candida guilliermondii C albicans and Microsporium gypseum with the minimal inhibitory concentration (MIC) values of 12.5 mu g/ml.
