槐花精油的化学成分及其抑菌活性的研究

采用同时蒸馏萃取法提取槐花精油,用气相-质普联用技术(GC-MS)分析其化学成分;鉴定出43种化合物,占出峰总面积的98.49 %;主要成分为十六酸(38.69%)、亚油酸甲酯(10.13%)、2-甲氧基-4-(2-丙烯基)-苯酚(6.71%)、亚麻酸(6.35%)、2-羟基-3-甲基-4H-吡喃-4-酮(3.49%)、8-十七碳烯(2.44%)、二苯砜(2.44%)、6,10,14-三甲基-2-十五酮(1.85%)、4-乙烯基-2-甲氧基苯酚(1.82%)等.体外抑菌实验显示该精油对金黄色葡萄球菌ATCC 6538、伤寒沙门氏菌CMCC50013、志贺氏痢疾杆菌CMCC51334、埃希氏大肠杆菌ATCC 8099均有抑制作用.

Chemical Composition and Antimicrobial Activity of Essential Oil from Flos Sophorae Immaturus

The chemical composition of the essential oil obtained from Flos Sophorae Immaturus by simultaneous distillation-extraction was analyzed by GC-MS. 43 Kinds of compounds (about 98.49% of the total peak areas) in the essential oil were identified and the major components were hexadecanoic acid(38.69%), 9,12-octadecadienoic acid methyl ester(10.13%), 2-methoxy-4-(2-propenyl)-phenol(6.71%), 9,12,15-Octadecatrienoic acid (6.35%), 2-hydroxy-3-methyl-4H-pyran-4-ketone(3.49%), 8-heptadecene(2.44%), 1,1''-sulfonylbis-benzene (2.44%), 6,10,14-trimethyl-2-pentadecanone(1.85%), 4-vinyl-2-methoxy-phenol(1.82%). In vitro antimicrobial experiments showed that the essential oil had antibacterial activities against Staphylococcus aureus ATCC 6538, Salmonella typhi CMCC 50013, Shigella dysenteriae CMCC 51334 and Escherichia coli ATCC 8099.
