三种阿魏根提取物的体外抑菌作用研究

Study on Antimicrobial Activity in vitro of Extracts from Three Species of Ferula Root

以新疆阿魏、多伞阿魏和大果阿魏为试材,采用滤纸片扩散法对其根的浸提物和醇提物进行体外抑菌试验。结果表明:在2种提取方法中醇提物比浸提物的抑菌效果明显;3种阿魏根的根醇提取物对金黄色葡萄球菌、枯草芽孢杆菌和八叠球菌均具有较好抑菌作用,对大肠杆菌无抑菌作用,其中多伞阿魏的抑制作用最强;根浸提物中大果阿魏的抑制作用最弱,仅对枯草芽孢杆菌有明显的抑菌效果。

Taking Ferula sinkiangensis ,F. ferulaeoides and F. lohmanni as test materials,bacteriostatic test in vitro of root extract and alcohol extract were done using filter paper diffusion method. The results showed that：the bacteriostatic effects of alcohol extract was better than extracts significantly; alcohol extracts of 3 species of Ferula root against Staphylococcus aureus ,Bacillus subtilis and Sarcine sp. had good antibacterial effect,no inhibitory effect on Escherichia coli ,among which the strongest inhibitory effect was E. ferulaeoides extract; F. lohmanni extract had the weakest inhibitory action,only had obvious bacteriostasis effect on Bacillus subtilis.
