裸花紫珠叶抑菌性物质的ASE联合牛津杯和微孔刃天青法筛选
目的 筛选6种不同极性溶剂提取物对6种常见菌抑菌性好的溶剂和菌株.方法 利用快速提取仪(ASE)和6种不同极性溶剂对裸花紫珠叶进行提取,对6种常见菌进行定性的牛津杯法抑菌实验;对大肠杆菌和枯草芽孢杆菌两种菌进行定量的微孔板刃天青法筛选实验,测定5种提取液对大肠杆菌和枯草芽孢杆菌作用测得的(低抑菌浓度)MIC值.结果 除了水提药液,其他5种对不同的菌有不同的抑菌圈,但乙醇和正丁醇段对大肠杆菌和枯草芽孢杆菌都有较好的抑菌圈;在相同作用条件下,相比其他3种提取药液,乙醇和正丁醇有较低的的抑菌浓度,分别为0.022g· m1-1和0.033g·ml-,但正丁醇比乙醇有较高的抑菌性和毒性.结论 终可筛选乙醇作为裸花紫珠叶的提取剂,且可以得出提取液药液对大肠杆菌和枯草芽孢杆菌有较好的抑菌性.
