摘　　要：采用溶剂萃取法制备5种江香薷提取物,并用纸片法和肉汤稀释法比较了这5种提取物分别对金黄色葡萄球菌、大肠杆菌和枯草芽孢杆菌等常见菌的体外抗菌效果,结果显示江香薷的乙酸乙酯提取物对三种检测细菌的MIC为15.60μg/mL,石油醚提取物、正丁醇提取物和醇溶物的MIC为31.25μg/mL,而水提物在实验浓度范围内抗菌作用不明显。由此可知江香薷具有抗菌活性,其中以乙酸乙酯提取物作用最显著。Five different polarity extracts from Mosla chinensis ＇Jiangxiangru＇ were prepared by solvent extraction method. To compare the bacteriostatic activity of different extracts on Staphylococcus.aureus,Escherichia.coli and Bacillus subtilis,disk diffusion method and broth dilution method were used. The results showed that four organic solvent extracts had various bacteriostatic activities on the tested germ, but the aqueous extract had little bacteriostatic activity. In addition,the ethyl acetate extract had the lowest MIC（minimal inhibitory concentration） ,which was 15.60μg/mL. While,MIC of petroleum ether extract and ethanol extract were 31.25μg/mL. Thus, Mosla chinensis ＇Jiangxiangru＇ had antibacterial activity,and the ethyl acetate extract had the most significant effect.
