| 中文摘要: |
| 探讨紫茎泽兰(Eupatorium adenophorum) 95%乙醇、石油醚、尧乙酸乙酯、尧正丁醇、甲醇5种粗提物的体外抗菌效果。通过倍比稀释法分析紫茎泽兰5种提取物对大肠埃希氏菌、金黄色葡萄球菌、痢疾杆菌和白色念珠菌的最小抑菌浓度（MIC）和最小杀菌浓度(MBC)。试验结果表明：紫茎泽兰乙酸乙酯粗提物的抑菌效果最显著，当其浓度为12.5 mg/mL时,对大肠杆菌尧金黄色葡萄球菌尧痢疾杆菌有明显的抑制作用，当其浓度为6.25 mg/mL时,对白色念珠菌的抑菌效果明显。紫茎泽兰5种粗提物对白色念珠菌的抑菌作用均大于对大肠杆菌、金黄色葡萄球菌、痢疾杆菌的抑菌作用。说明紫茎泽兰5种粗提物对人类常见致病菌有明显的抑制和杀灭作用，在抑菌方面有一定的价值。 |
| 英文摘要: |
| To investigate the antibacterial activity in vitro of Eupatorium adenophorum extracts, authors used 95% ethanol, petroleum ether, ethyl acetate, n-butanol and methanol to extract the antibacterial ingredients. The antibacterial activities (MBC and MIC) were analyzed with Escherichia coli, Staphylococcus aureus, Shigella dysenteriae and Candida albicans by double dilution method. The result showed that E. adenophorum extracts used by ethyl acetate had the significant antibacterial effect on E. coli, S. aureus and S. dysenteriae,when its concentration was 12.5 mg/mL. When its concentration was 6.25 mg/mL, it could significantly suppress C. albicans. 5 E.adenophorum extracts had higher suppression effect on C. albicans than E. coli, S. aureus and S. dysenteriae. The result indicated that 5 E.adenophorum extracts could significantly inhibit and kill common human pathogens. Therefore, the extracts from E. adenophorum may have a certain development value in antibacterial aspects. |
