分别以乙醇和丙酮为溶剂,从9种苔藓植物中提取有效成分,利用滤纸片法将提取液作用于3种供试菌株,研究其抑菌能力,并对提取液的最低抑菌浓度(MIC)进行了测定,结果如下:9种苔藓植物中多数均对目的菌株具有一定的抑制作用,且表现出对金黄色葡萄球菌和枯草芽孢杆菌的生长抑制作用较强,而对大肠杆菌的生长抑制作用相对较弱。 The effective components were extracted from 9 kinds of bryophytes with ethanol and acetone respectively. The extracts were applied to three kinds of tested strains by the filter paper method to study their bacteriostasis ability. The minimum inhibitory concentration (MIC ) Were determined. The results were as follows: Most of the 9 species of bryophytes had a certain inhibitory effect on the target strains, and showed a strong growth inhibitory effect on Staphylococcus aureus and Bacillus subtilis, but inhibited the growth of E. coli The role is relatively weak.
