Abstract:

A automatic solid-phase extraction- ultra-performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS) method was established for the determination of 76 glucocorticoids in cosmetics. The mass spectrometer was operated by electrospray ionization and positive multiple reaction monitoring. The cosmetics with liquid water-based, emulsion and cream were investigated. The samples were dispersed in saturated sodium chloride solution, extracted with acetonitrile, and purified by automatic solid-phase extraction apparatus. The results show that the limits of detection (LODs) for 76 glucocorticoids are in the range of 0.004-0.024 μg/g. Good linear relationship exists between peak area and mass concentration of 10-100 ng/mL with correlation coefficients higher than 0.99. The average recoveries are in the range of 76.1%-120.8%, with relative standard deviations (RSDs) of 0.4%-13.0%.The method is simple, efficient, sensitive, reliable,and is suitable for the general detection of 76 glucocorticoids in various kinds of cosmetics.

Key words: cosmetics, glucocorticoids, automatic solid-phase extraction, ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS)
