摘　　要：从海南桉叶中提取有效组分熊果醇和桉叶油,并研究了其抑菌活性。结果表明,熊果醇对枯草芽孢杆菌、金黄色葡萄球菌、白色念珠菌、大肠杆菌和短小芽孢杆菌等有明显的抑制作用,对藤黄微球菌没有抑制作用,对大肠杆菌的最低抑菌浓度(MIC)为587μg.mL-1;桉叶油只对大肠杆菌、白色念珠菌有较明显的抑制作用。Uvaol and eucalyptus oil were separated from Hainan Eucalyptus urophylly leaves,and their antibacterial activities were studied.The results showed that,uvaol had obvious antimicrobial action to Bacillus subtilis,Staphylococcus aureus,Candida albicans,Escherichia coli and Bacillus pumilus,but it was not effective to Micrococcus luteus.Its minimal inhibition concentration（MIC） for Escherichia coli was 587 μg·mL-1.The eucalyptus oil had some effects to Escherichia coli,Candida albicans.
