Abstract

The ethanol extract and fractions from Coccoloba acrostichoides aerial parts were assayed for in vitro antimicrobial activity. The extract was active against the assayed bacteria while most of the fractions also inhibited fungal growth, especially the n-hexane and EtOAc fractions. The isolated beta-sitosterol and betulin were tested, being the last one active against Fusarium oxysporum.

摘要

对海葡萄（Coccoloba acrostichoides）地上部分的乙醇提取物及其馏分进行了体外抗菌活性测定。该提取物对所检测的细菌具有活性，而大多数馏分也能抑制真菌生长，尤其是正己烷和乙酸乙酯馏分。对分离得到的β-谷甾醇和桦木醇进行了测试，其中桦木醇对尖孢镰刀菌具有活性。
