| 摘要: |
| 分别以无水乙醇、乙酸乙酯、三氯甲烷、蒸馏水和丙酮作为提取剂,用回流提取的方式提取蓝萼香茶菜[Isodon japonica(Burm.f.)Hara var.glaucocalyx(Maxim.)Hara]的5种提取液,分别采用滤纸片法和平板稀释法测定提取液对大肠埃希氏菌、金黄色葡萄球菌、变形杆菌、米曲菌的抑菌效力及最低抑菌浓度(MIC)。结果显示,5种提取液对实验菌均有抑菌作用,对4种致病菌的MIC的排列顺序为:无水乙醇提取液 < 三氯甲烷提取液 < 丙酮提取液 < 乙酸乙酯提取液 < 蒸馏水提取液。 |

| Abstract: |
| We used pure alcohol, ethyl acetale, chlorpicrin, distilled water, and aceton as extractant respectively to extract Isodon japonica (Berm.f.)Hara var.glaucocalyx (Maxim.)Hara.Backflow extration with filter paper or flat dilution is used.The antibacterial activity and the minimum inhibition concentration (MIC) was performed.The result showed that the five kinds of extract have the antimicrobial function, to four kinds of pathogenic bacteria's MIC order of rank is:The absolute alcohol to extract < the chlorpicrin to extract < the acetone to extract < the ethyl acetate to extract < the distilled water to extract. |
