Abstract: A method for the simultaneous determination of residue of 15 kinds of glucocorticoid and sex hormone in cosmetics by gel permeation chromatography-liquid chromatography-tandem mass spectrometry (GPC-LC-MS/MS) was established.The sample was extracted with acetonitrile under ultrasonic assistance,and the extract was purified with GPC column of cyclohexane-ethyl acetate.Then the contents in the purified extract were separated by a C18 column with acetonitrile-0.1% formic acid solution as the mobile phase,and then detected by LC-MS/MS.Testing results showed that good linearity was obtained with correlation coefficients higher than 0.995.The detection limit ranges within 0.1-4.0 mg·kg-1.The spiked recovery ranges within 70.0%-104.0%,and the RSD ranges within 5.3%-15.5%.

Key words: cosmetics, glucocorticoid, sex hormone, GPC, LC-MS/MS
