无花果叶提取物的抑菌作用研究

Study on antibacterial activity of Ficus carical leaves extracts

为探讨无花果叶逐级提取物的抑菌作用,实验测定了无花果叶逐级提取物对各实验菌种的抑菌圈及最低抑菌浓度,结果表明各级提取物对实验菌分别有不同程度的抑菌作用,其中对金黄色葡萄球菌和枯草杆菌的抑菌作用最为明显,各级提取物的抑菌强度依次为:乙酸乙酯萃取物(金黄色葡萄球菌:MIC≤6.25mg/mL,枯草杆菌MIC:≤12.5mg/mL)、正丁醇萃取液(两种菌的抑菌作用:MIC≤25mg/mL)、石油醚萃取液(两种菌的抑菌作用:MIC≤50mg/mL),其中乙酸乙酯萃取物的抑菌活性最强。

To study the antibacterial activity of Ficus Carlcal leaf extract, minimal inhibitory concentration （MIC） and inhibitory circle of the extract were determined. The results showed that the antibacterial activity of the extracts was different toward different microbes. The sensitivity to ethylacetate extract in sequence was （Staphylococcus aureus：MIC ≤6.25mg/mL, Bacjllus subtilis：MIC ≤12.5mg/mL）, to n-butanol extract （Staphylococcus aureus：MIC ≤25mg/mL, Bacillus subtilis：MIC ≤25mg/mL）, to petroleum ether extract （Staphylococcus aureus：MIC ≤50mg/mL, Bacjllus subtilis ： MIC ≤50mg/mL）.The antibacterial activity of ethylacetate extract was the most potent.
