Abstract:

A method of ultra high performance liquid chromatography-tandem mass spectrometry was developed for simultaneous determination of 14 sexual hormones in cosmetics without matrix effects. After the sample was dispersed in saturated sodium chloride, it was extracted with acetonitrile, frozen and centrifuged, and diluted 10 times with acetonitrile to eliminate the matrix effect. The extracts were separated using gradient elution of water and methanol as mobile phase. The analysis of the target compounds was performed under multiple reaction monitoring. The results show that the 14 sexual hormones have a good linearity in the range of 10-200 μg/L with correlation coefficients (r) more than 0.995, and the average recoveries of the method are 90.8%-115.2%. This method is accurate, sensitive, specific, low detection limit and can be used for the qualitative and quantitative determinations of 14 kinds of sexual hormones in cosmetics.

Key words: ultra high performance liquid chromatography-tandem mass spectrometry, cosmetics, sexual hormones
