摘　　要：从9种植物中筛选出对几种致病菌及青霉菌抑菌效力显著的丁香、艾叶、紫苏、青蒿、辣椒及花椒6种材料,通过二倍稀释法确定其最低抑菌浓度。结果表明:紫苏对大肠杆菌抑制力最强,其MIC为0.391%;6种提取物对金黄色葡萄球菌都有很强的抑制力,除花椒外,其他5种提取液的MIC均为0.391%;艾叶、辣椒、花椒对白色念珠菌有较强的抑制力,MIC为0.782%;丁香和辣椒对青霉菌的作用效果最好,MIC为0.391%。最后复配了由等量丁香、辣椒、花椒组成的防腐剂配方,其抑菌效力明显高于苯甲酸钠。Clove, Folium Artemisiae argy, perilla, Artemisia annua, Capsicum frutescens and bunge prickly ash with remarkable antibacterial activity on three kinds of pathogens and Penicillium sp.were selected from 9 herbs.And the minimum inhibitory concentration（MIC） of six kinds of plant extract to Ecofi, Stophylococcus aureus, Candida albicans and Penicillium sp.were determined through double broth dilution method.The results showed that the extract from perilla possessed the highest antibacterial activity against Ecoli and the MIC was 0.391%.The six kinds of plant extract all had remarkable antibacterial activity on Stophylococcus aureus, the five of them, except for bunge prickly ash, had the same MIC of 0.391%.The extract from Folium Artemisiae argy, Capsicum frutescens apd bunge prickly ash showed an efficient antibacterial activity on Candida albicans, the MIC was 0.782%.The extract from Clove and Capsicum frutescens possessed the highest antibacterial activity against Penicillium sp.and the MIC was 0.391%. Moreover, the combinatorial formulas with extract from Clove, Capsicum frutescens and bunge prickly ash exhibited a higher antibacterial activity than Sodium benzoate.
