| 摘 要： | A new flavonol glycoside,isorhamnetin-3-O- β-D-xyloside,was isolated from the extract of leaves and twigs of Alchornea davidii (Euphorbiaceae).Its structure was established on the basis of the spectral analysis and chemical degradation.Antimicrobial assay showed that it moderately inhibited the growth of test bacteria (Staphylocoocu aureus,Bacillus subtilis and Pseudomonas fluorescens)and fungi (Candida albicans,Aspergillus niger and Trichophyton rubrum) with MICs at 50μg/ml.
