中药金银花药用成分的提取及抑菌实验的研究

为了研究金银花中抗菌消炎成分总黄酮、绿原酸的提取方法及其抑菌效果，本实验中用金银花的提取物对11种菌种进行筛选，并对其中有抑制作用的菌种进行了最小抑菌浓度的实验。结果表明金银花的提取物对金黄色葡萄球菌和大肠杆菌有较强的抑制作用，对金黄色葡萄球菌的MIC为6．25mg／ml，对大肠杆菌的MIC为12．5mg／ml。

EXTRACTION OF ACTIVE COMPONENTS FROM FLOS LONICERAE AND THEIR BACTERIOSTATIC TEST

To extract the active components from Flos Lonicerae and do their bacteriostatic test. The bacteriostatic test was experimented with eleven different bacterium. The effective bacterium was f iltrated, the MIC of extraction was determined, too. Result showed that extraction from Flos Lonicerae might be more effective a-gents against staphylococcus aures and coliform. The MIC of extraction from Flos Lonicerae against staphylococ-cus aures was 6.25mg/ml,and the MIC against coliform was 12.5 mg/ml.
