1、第42卷第3期当代化工Vo1.42.NO.32013年3月ContemporaryChemicalIndustryMarch.20i3羧甲基槲皮素的体外抑菌活性研究隋阳,郭影坤(东北制药集团供销有限公司,辽宁沈阳110023)摘要:考察了槲皮素的水溶性衍生物3一羧甲基槲皮素钠及4一羧甲基槲皮素钠的体外抑菌活性。方法:用培养基将3一羧甲基槲皮素钠及4一羧甲基槲皮素钠进行倍比稀释,加入菌液至终浓度为107cfu·mL~,通过比浊法测定加药后细菌的生长情况。结果是3一羧甲基槲皮素钠对金黄色葡萄球菌Staphylococcusaureus、金黄色葡萄球菌W
2、right、肺炎克雷伯菌、大肠杆菌、中间普氏菌的最小抑菌浓度分别为0.05,0.1,0.8mg·mL~,1.6,0.05mg·mL;最小抑菌浓度下的抑菌率分别为98.8%,87-3%,83.9%,100.O%,100.0%。4一羧甲基槲皮素钠对金黄色葡萄球菌、带荚膜的金黄色葡萄球菌、肺炎克雷伯菌、大肠杆菌、中间普氏菌的最小抑菌浓度分别为0.05,0.1,0.8,1.6,0.05mg·mL‘;最小抑菌浓度下的抑菌率分别为92.4%,78.6%,87.5%,97.9%,99.8%。结论:3一羧甲基槲皮素钠及4一羧甲基槲皮素钠对革兰阳性菌、革兰阴性菌及厌
