摘　　要：目的:比较车前草不同提取物的抗菌活性。方法:采用分光光度比浊法,用车前草的8种溶剂室温提取物对3种细菌进行抗菌活性研究,8种溶剂分别是自来水、超纯水、无水乙醇、甲醇、乙醚、石油醚、三氯甲烷和苯。结果:车前草提取物C、D、E、G、H均有抗菌活性(P<0.05),提取物A、B没有抗菌活性(P>0.05)。结论:车前草的不同有机溶剂提取物均有良好的体外抗菌活性。Objective： To compare the antibacterial ability of extracts that was extracted by different dissolvent from plantain.Methods： Tap-water,ultra-pure water,ethanol,methanol,ether,petroleum ether,chloroform and benzene were used to extract the antibacterial ingredients of plantain at room temperature;three kind bacteria were medium containing different extracts,and Spectrophotometry assays were performed to measure the antibacterial ability of extracts.Results： The antibacterial ability of extracts according to C,D,E,G,H（P〈0.05） priority was ingredient extracted.Ingredients extracted by Tap-water,ultra-pure water display non-antibacterial ability（P0.05）.Conclusion： Organic solvents were more effective as dissolvent to extract antibacterial ingredients of plantain.
