摘　　要：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ATCC6538、伤寒沙门氏菌CMCC50013、志贺氏痢疾杆菌CMCC51334、埃希氏大肠杆菌ATCC8099均有抑制作用。The chemical composition of the essential oil obtained from Flos Sophorae Immaturus by simultaneous distillation-extraction was analyzed by C-C-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.
