几种中草药对金黄色葡萄球菌体外抑制作用的研究

In vitro Antibacterial Effect of Several Common Chinese Medicinal Herbs on Staphlococcus aureus

研究了板蓝根、五倍子、鱼腥草等10种常见中草药对金黄色葡萄球菌的抑菌作用。用平皿打孔法、两倍稀释法等不同方法分别测定不同浓度的中草药提取液对金黄色葡萄球菌的抑菌圈的大小、最小抑菌浓度和最小杀菌浓度。抑菌圈的结果表明五倍子的抑菌效果最好,其次依次为黄芩、板蓝根、金银花、甘草、黄连、鱼腥草、虎杖与芦荟、黄芪;最小抑菌浓度和最小杀菌浓度结果显示金黄色葡萄球菌对所测试中草药的敏感程度不同,按抑菌浓度由小到大的顺序排列依次为五倍子、黄芩与金银花、板蓝根、甘草与黄连、虎杖与鱼腥草、黄芪、芦荟。可见所测试中草药对金黄色葡萄球菌均有不同程度的抑制作用。

The antibacterial effects in vitro of 10 kinds of Chinese medicinal herbs （such as radix isafidis, Chinese gall, herba houttuynia） on Staphlococcus aureus were studied. Stiletto and dilution methods were used to detect the inhibition zone, MIC, MBC to Staphlococcus aureus of Chinese medicine herbs at different concentrations. The bigger inhibition zone was found with Chinese gall, followed by Baieat skullcap root , Radix isatidis, Honeysuckle, Liquorice, Rhizoma coptidis, Herba houttuynia, Polygonum cuspidatum and Aloe, Astragalus hoangtchy sorted by size. By the MIC and MBC analysis, Chinese gall showed the highest the antimicrobial activity, followed by Baical skullcap root and Honeysuckle, Radix isatidis ect.
