摘要：

目的了解佛手对金黄色葡萄球菌、大肠埃希菌等8种常见致病菌的抗菌作用及其抗氧化性能。方法分别用80%的甲醇水提取新鲜成熟的佛手及其烘干制品的酚类物质。采用微量稀释法,测定其提取液对金黄色葡萄球菌、大肠埃希氏菌、鼠伤寒沙门氏菌、福氏志贺氏菌、铜绿假单胞菌、蜡样芽孢杆菌、表皮葡萄球菌及白色念珠菌8种常见致病菌的最小抑菌浓度及最小杀菌浓度,并对其抗菌活性进行评价;采用紫外可见分光光度计测定其氧化还原能力及清除自由基能力,对其抗氧化活性进行评价。结果佛手提取液对革兰阳性菌的抗菌作用强于革兰阴性菌。烘干后的佛手提取液的抗氧化作用强于新鲜佛手。结论佛手对常见的致病菌有较强的抗菌作用,可以开发其成为新型天然抑菌剂。
