1、醉鱼草提取物抑菌效果的研究摘要随着公众对“绿色食品”、“无公害食品”的要求越来越高,市场对植物源抑菌剂的需求量也逐渐增多。可见,大力发展植物源抑菌剂是社会、市场、公众的需要。醉鱼草(BuddlejalindleyanaFort)为马钱科醉鱼草属植物,为落叶灌木,高1~2.5米。具有祛风除湿,止咳化痰,散瘀,杀虫,抑菌等作用。醉鱼草原产世界热带和亚热带地区。在我国分布于江西,湖南,湖北,安徽等地。本实验主要是用醉鱼草提取物进行抑菌实验,采取的提取剂主要有水和95%的酒精,提取方式为索式提取,提取之后旋转蒸发得膏状物,再用水溶解,进行萃取实验,萃取剂主要有乙酸乙酯,正丁醇等。用萃取
2、后不同相中溶液进行抑菌实验,用测量抑菌圈大小确定各相中抑菌效果。本实验所用病菌为:稻瘟病菌,黄瓜病菌,柱孢杆菌,茶媒一号等。关键词:醉鱼草,抑菌,索式提取法15AbstractAspublicsonthedemandof"greenfood","pollution-freefood"ishigherandhigher,themarket’sdemandfortheplantsourceantibacterialagentisincreasing.Visibly,strivingtodeveloptheplantsourceantibacterialagentistheneedo
