Abstract: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.
