摘　　要：为探讨大叶桉不同溶剂提取物的抑菌作用,以大叶桉叶片为材料,采用琼脂平板打孔法对叶片不同溶剂提取物进行了抑菌活性研究。结果表明,大叶桉不同溶剂提取物对供试细菌(金黄色葡萄球菌、大肠杆菌、枯草芽孢杆菌)和真菌(绿色木霉菌、青霉菌)均具有不同程度的抑制效果,其中甲醇和95%乙醇提取物的抑菌作用相对明显。Antimicrobial activities of Eucalyptus robusta Smith leaves extract with six organic solvents against three bacteria （ Staphylococcus aureus, Escherichia coli and Bacillus subtilis ） and two fungi （ Trichoderma viride and Penicillium ） was studied by agar -well diffusion method. The results indicated that all six extracts showed some inhibitory effect against tested bacteria and fungi,and the methanol as well as 95% ethanol crude extracts had higher inhibitory activity than other solvents extracts.
