摘要
目的:从紫地榆乙酸乙酯部位分离得到不同组分,并对其进行体外抗菌活性研究。方法:通过大孔树脂柱对紫地榆乙酸乙酯部位分离,分别用水和不同浓度的乙醇进行梯度洗脱,不同极性提取物用常量试管稀释法对13株常见病原菌和10株耐甲氧西林金黄色葡萄球菌进行抑菌作用研究。结果:水部位提取物对标准菌株无明显抑菌活性;50%乙醇提取物对13株常见病原菌和10株临床分离的MRSA均有不同程度的抑菌作用。结论:紫地榆50%乙醇提取物在体外有不同程度的抑菌活性。
Objective:To study the antibacterial activity in vitro of different extracts isolated from the part of ethyl acetate extracted from Geranium strictipes R. Kunth. Methods: The ethyl acetate extracts were eluted by H2O and the different concentration of the ethanol through the macro-porous resin column, then the antibacterial effects of different extracts on the 13 common pathogenic bacteria and MRSA were conducted by the method of constant tube dilution. Results: Water extract had no obviously antibacterial activity on the standard bacterial strains. 50% ethanol extracts had a certain antibacterial activity at different degree on 13 common pathogenic bacteria and 10 MRSA. Conclusion: The 50% ethanol extracts from Geranium strictipes R. Kunth have significant antibacterial effect in vitro.
