摘　　要：采用滤纸片法测定凤仙花叶片55%乙醇回流提取物及其所含的指甲花醌、2-甲氧基指甲花醌对大肠杆菌、绿脓杆菌、白色念珠菌抑制活性。结果表明,凤仙花叶片提取物在25.0 mg/m L时对受试的3种菌均有较好的抑制作用。指甲花醌浓度为1.56 mg/m L时,对白色念珠菌、绿脓杆菌的抑菌活性强于对大肠杆菌的抑制作用。2-甲氧基指甲花醌对白色念珠菌的抑菌活性强于对绿脓杆菌、大肠杆菌的抑制作用,对白色念珠菌的最低抑制浓度小于0.78 mg/m L。The aim of this study was to investigate antimicrobial activities of 55% ethanol leave extrac- tion, lawsone and 2 - methoxy - 1,4 - naphthoquinone of Impatiens balsamina L. to bacteria （ such as Escherichia coli, Psettdomonas aeruginosa） and fungi （such as Candida albicans）. The results revealed that leave extraction at the concentration of 25.0 mg/mL can inhibit three kinds of bacteria, inhibition of bacterial is ： C. albicans 〉 P. aeruginosa 〉 E. coli. Lawsone at the concentration of 1.56 mg/mL can better inhibit C. albicans and P. aeruginosa than E. coli. 2 - Methoxy - 1,4 - naphthoquinone at the concentration of 0.78 mg/mL can better inhibit C. albicans than P. aeruginosa and E. coli.
