[目的]研究车前草不同提取物的抗菌活性,比较提取物的抗菌能力.[方法]将车前草以8种不同溶剂进行室温提取,采用分光光度比浊法测定不同提取物在96孔板中对3种细菌的抗菌活性.[结果]抗菌活性最好的是车前草无水乙醇提取物(P＜0.05),乙醚提取物和无水甲醇提取物次之,自来水和超纯水提取物没有抗菌活性.[结论]车前草的不同溶剂提取物均具有一定的抗菌活性,对金黄色葡萄球菌和大肠杆菌的抑制作用最为明显,对绿脓杆菌的抑制作用也较好.%[ Objective ] The aim was to study the antibacterial activity of different extracts from Plaatago asiatica L. , and compare their antibacterial capacity. [Method] The Plantago asiatica L. was extracted with eight different solvents under room temperature, and the antibacterial activity of different extracts against three bacteria in the 96- wells dish was determined by spectmphotometry. [Result] The best antibacterial activity waft found in the anhydrous ethanol extracts (P <0.05) , then followed by the ether and anhydrous methanol extracts, the extracts by running water and ultrapure water had no antibacterial activity. [Conclusion] The extracts of Plantago asiatica L. with different solvents all show certain antibacterial activity, especially against Staphyloccocus aweus and Escherich coll, the inhibitive effect against P. aeruginosa was.also good.
