摘要: 萹蓄(Polygonum aviculare L.)是一种常用中药,具有杀虫止痒,治疗黄疸等功效。本文采用打孔法分别对其乙酸乙酯部位分离得到的十个化合物进行了抑菌活性实验,结果表明,除化合物1、2、9、10外,其它化合物均对不同的菌种呈现出不同的抑菌活性,并且呈一定的剂量效应。本实验为萹蓄及其化学成分作为天然的抑菌活性物质研究开发提供理论依据。

Abstract: Polygonum aviculare L.was used for the treatment of cutaneous pruritus and jaundice.In current study,antibacterial activities of ten compounds isolated from ethyl acetate extract of P.aviculare were tested.The results showed that these compounds (except for 1,2,9 and 10) showed inhibitory activity against different bacteria with dose-dependent effect.This indicated that P.aviculare and its components can be regarded as a potential source of natural antibacterial agent in the prevention and treatment of microbial infections.

Key words: Polygonum aviculare L., antibacterial activity;myricetin- 3-O-(3′′-O-galloyl)-rhamnopyranoside;inhibition zone
