Abstract:

An ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of 39 sex hormones in oil-based cosmetics. The sample was dispersed with n-hexane, then extracted with 70% acetonitrile, and separated on a CORTECS C18 (2.1 mm×150 mm, 2.7 μm) column by gradient elution using acetonitrile-water as mobile phase. The analysis was performed under multiple reaction monitoring (MRM) mode. The results showed that the matrix effects of 39 sex hormones were 0.78-1.26. The limits of detection (LODs) and limits of quantitation (LOQs) for 39 sex hormones were in the range of 0.6-2.3 μg/L and 1.9~6.8 μg/L, respectively. There was good linear relationship for 39 sex hormones in the mass concentration range of 1.87-67.41 μg/L with their correlation coefficients (r) all above 0.995. The average recoveries at three spiked levels of 0.25, 0.50 and 1.00 μg/g were in the range of 81.7%-110.6%, with relative standard deviations (RSDs, n=6) of 1.2%-14.1%. The simplicity and accuracy of this method make it suitable for the analysis of sex hormones in oil-based cosmetics.
