| 摘 要： | 以耐甲氧西林金黄色葡萄球菌（MRS）、大肠杆菌、普通金黄色葡萄球菌、普通变形杆菌、枯草芽孢杆菌为供试菌种，采用滤纸片琼脂扩散法研究胆木叶提取物的体外抑菌活性。结果表明，以40％以上体积分数乙醇为提取剂时，胆木叶提取物对MRS具有抑静活性，且乙醇的体积分数越大，提取物的抑菌活性越强；胆木叶乙醇提取物中的中高极性溶剂萃取段抑菌活性最强。胆木叶水煮液对大肠杆菌具有抑菌活性，醇提液对大肠杆菌只有极弱的抑菌活性。胆木叶醇提液和水煮液对普通金黄色葡萄球菌、普通变形杆菌、枯草芽孢杆菌只有极弱的抑菌活性。 |

| Abstract: | With methicillin-resistant staphylococcus aureus(MRS),escherichia coli,staphylococcus arureus,proteus vulgaris,bacillus subtilis as the tested strains,the vitro antibacterial activity of extracts from Nauclea officeinalis leaves was determined by filter paper agar diffusion method.The results showed that the extract from N.officeinalis leaves had antibacterial activity on MRS when ethanol which volume fraction was more than 40% was taken as extractant,and the bigger the volume fraction of ethanol was the st... |
