Abstract:

An ultra-high performance liquid chromatography method was established for determination of 22 sex hormones in water-based cosmetics. The sample was ultrasonically extracted with 80% acetonitrile solution. After centrifugation, the supernatant was purified by PRiME HLB column. Chromatographic separation was achieved on an CORTECS C18+ (2.1 mm×100 mm, 2.7 μm) column by gradient elution using acetonitrile-water as mobile phases. PDA detector was used to test samples by multiple wavelengths, and external standard method was used for quantification. The results show that there are good linear relationships for 22 sex hormones in the respective concentration range with their correlation coefficients (r) all above 0.99. The limits of detection (LOD) and limits of quantitation (LOQ) for 22 sex hormones are in the range of 0.03-0.1 μg/mL and 0.1-0.4 μg/mL, respectively. Average recoveries at three levels of 5,25,50 μg/g are in the range of 80.3%-99.6%, with relative standard deviations(RSD, n=6) of 0.3%-7.7%. With the advantages of simplicity, sensitivity and accuracy, this method is suitable for the analysis of sex hormones in water-based cosmetics.
