Unilateral Bacteriostatic Effect of Several Common Wild Herbs Collected from Henan Zhoukou Area

[目的]研究6种中草药对大肠杆菌、金黄色葡萄球菌的单方抑菌效果。[方法]采用水煎剂法提取6种中草药有效成分,采用滤纸片扩散法检测抑菌效果。[结果]6种中草药对大肠杆菌、金黄色葡萄球菌均有明显的抑菌作用,并且随浓度增加抑菌效果增强。6中草药对大肠杆菌、金黄色葡萄球菌的最佳抑菌浓度均为1.000 0 g/ml(个别除外),但相同浓度下,抑菌效果也不同。[结论]野菊花、蛇莓、地黄、泽漆、紫苏和荔枝草6种中草药有效成分对大肠杆菌和金黄色葡萄球菌均有明显的抑菌作用。
