| Abstract: | A new method for simultaneous separation and determination of five coumarins (3,4-dihydro-coumarin, 7-methoxycoumarin, acenocoumarol, 7-methylcoumarin, 7-ethoxy-4-methyl-2H-chromen-2-one) in cosmetics was developed by GC-MS. The coumarins were extracted with ethanol using vortex and centrifuged. The recoveries were 85.4%～107.6%, and the relative standard deviations were 5.6%～11%. |
