摘要:研究不同科属植物提取物对食源性致病菌的抑制作用。制备景天科植物乙醇提取物、百合科植物乙醇提取物、马齿苋科植物乙醇提取物、菊科植物乙醇提取物、番杏科植物乙醇提取物，采用滤纸片法研究其抑菌性能，对各科属最优提取物采用薄层色谱法做相应的鉴定。景天科、百合科、菊科、马齿苋科、番杏科等五个科属植物对细菌有广泛的抑菌效果，其抑菌效果由强到弱为：马齿苋科、景天科、菊科、番杏科、百合科。
关 键 词： 植物提取物；食源性致病菌；抑菌；滤纸片法
Abstract:To study different genera of plant extracts on food-borne pathogenic bacteria inhibition. Preparation Orpine ethanol extract, the Liliaceae ethanol extract, ethanol extract of purslane plants, the Compositae ethanol extract, Aizoaceae plant ethanol extract, to study the antibacterial performance using the filter paper method,to analysis The best extraction of various genera using thin layer chromatography(TLC) .The five genera plants of Crassulaceae, liliaceous, compositae, purslane, apricot have a wide range of antibacterial effect ,The bacteriostatic effects from strong to weak is:Portulacaceae, crassulaceae, compositae, apricot, liliaceous.
