黄河三角洲2种菊科植物提取物及其复配的抑菌活性

目的]明确2种菊科植物的抑菌活性。方法]以干苦菜、黄花蒿作为供试材料,大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌作为供试细菌,采用滤纸片法通过抑菌圈的大小研究干苦菜、黄花蒿及其复配提取液的抑菌活性。结果]在供试浓度为0.1 g/m L时,2种植物的提取液及2种植物的复配混合液对枯草芽孢杆菌、大肠杆菌、金黄色葡萄球菌均有抑菌作用,并且每1种植物提取液对至少1种菌的抑菌率大于70%,其中黄花蒿提取液对金黄色葡萄球菌的抑菌率大于80%,苦菜提取液对大肠杆菌的抑菌率大于85%,苦菜与黄花蒿提取液的复配混合液对大肠杆菌的抑菌率约为100%。结论]苦菜、黄花蒿有较好的抑菌活性,可进一步研究开发。

The Antibacterial Activity of 2 Compositae Extracts and Compound in the Yellow River Delta

Objective] The aim was to determine the antibacterial activity of 2 Compositae plants.Method] With maror, annua as test materi-als, Escherichia coli, Bacillus subtilis and Staphylococcus aureus as tested bacterias, using filter paper method, the antibacterial activity of maror and annua and their composite liquids were analyzed by observing the size of inhibition zone.Result] The results showed that:when the concen-tration was 0.1 g/mL, the intermixtures and composite liquids of both plants inhabited three bacterias above, and the inhibitory rate of each plant’ s concentration was more than 70% at least, the rate of annua inhibiting Staphylococcus aureus was more than 80%, the rate of maror in-hibiting Escherichia coli was more than 85%, the compound liquid of maror, annua can inhabit Escherichia coli thoroughly, which means the in-hibitory rate was 100%.Conclusion] Maror and annua have good antibacterial activity, which can be further studied and developed.
