摘要
目的:研究芭蕉根和芭蕉花不同提取部位对金黄色葡萄球菌(SA)、耐甲氧西林的金黄色葡萄球菌(MRSA)和β-内酰胺酶阳性的金黄色葡萄球菌(ESBLs)的抑菌活性。方法:采用纸片扩散法测定不同提取部位的最低抑菌浓度(MIC)。结果:芭蕉根石油醚部位对SA,MRSA和ESBLs均有抑制作用,MIC全部为31.25μg·disc-1;芭蕉根正丁醇部位对MRSA,ESBLs有抑制作用,MIC都为250μg·disc-1;芭蕉花石油醚部位对SA、MRSA和ESBLs都有抑制作用,MIC均为125μg·disc-1。抑菌活性大小顺序为芭蕉根石油醚部位>芭蕉花石油醚部位>芭蕉根正丁醇部位。结论:芭蕉根和芭蕉花的石油醚部位是芭蕉的抑菌活性部位。
Objective: To study antimicrobial activity against SA,MRSA and ESBLs by Musa basjoo rhizome and flower.Method: Disc diffusion method was applied to determine the MIC value.Result: MIC in the petroleum ether extracts of the rhizome against SA,MRSA and ESBLs was 31.25 μg.disc-1.MIC in n-BuOH extract against MRSA and ESBLs was 250 μg.disc-1.MIC in the petroleum ether extracts of the flower against SA,MRSA and ESBLs was 125 μg.disc-1.The order of antimicrobial activity was petroleum ether extracts of rhizome petroleum ether extracts of flower n-BuOH extract of rhizome.Conclusion: Petroleum ether extracts of rhizome and flower were active fraction.
