摘要
选用常见的3种革兰氏阴性菌、2种革兰氏阳性菌及1种真菌对紫椴花提取物的抑菌效果进行了研究,并采用肉汤稀释法对每种提取物的最低抑菌浓度(MIC)及最低杀菌浓度(MBC)进行测定。结果表明:紫椴花乙酸乙酯萃取物对表皮葡萄球菌、金黄色葡萄球菌、柠檬色葡萄球菌、大肠杆菌、变形杆菌、白色念珠菌6种菌种均具有明显的抑菌活性,抑菌效果强于链霉素,其对革兰氏阳性菌及真菌的的抑菌效果好于革兰氏阴性菌。
We studied antibacterial effects of Tilia amurensis Rupr. inflorescence extracts on three Gram-negatives, two Gram- positives and one Fungus to provide theoretical basis for comprehensive exploitation and utilization of T. amurensis Rupr. resources. We measured MIC （minimum inhibitory concentration ） and MBC （minimum bactericidal concentration ） of each extract by using broth dilution method. The ethyl acetate extracts of T. amurensis Rupr. have significant antibacterial activity on Staphylococcus epidermidis, S. aureus, Staphylococcus citreus, Escherichia coli, Proteus vulgaris and Candida albicans and its antibacterial effect is better than that of streptomycin.
