【摘要】 为了研究西伯利亚花楸枝条乙醇提取物的体外抑菌特性,测定了提取物对一系列供试细菌和真菌的最低抑菌浓度、最低杀菌浓度,以金黄色葡萄球菌及大肠杆菌为例研究了提取物的热稳定性、紫外光稳定性,以金黄色葡萄球菌为例研究了提取物抑菌时间及抑菌率的关系,同时还进行了实物防腐实验。结果表明提取物对所有供试细菌及真菌都有明显的抑制作用,其最低抑菌浓度(MIC)较低;121℃湿热处理30min后,抑菌效应下降不大,具有良好的热稳定性及紫外光稳定性,其抑菌作用随抑菌时间的延长而增强,实物防腐实验效果良好。更多还原

【Abstract】 The antimicrobial effect of ethanol extract from Sorbus sibirica Branch for a series of bacterium and fungi were studied. The extract was also studied for its stability to temperature and ultraviolet radiation . The results indicated that the extract with a certain concentration could effectively inhibit the growth of bacteria and fungi. The MIC was lower and not reduced much when heated at under 121℃ for 30 min,it still shows a strong antiseptic power after a treatment of ultraviolet radiation. The extract has obvious antimicrobial effect on animal tests.更多还原
