Abstract:

An UHPLC-MS/MS method was developed for the determination of glabridin in cosmetic containing licorice. The glabridin in facial cream and toner samples was extracted with ethyl acetate and methanol, respectively. After optimizing the sample pretreatment and chromatography conditions, as well as mass spectrometry parameters, UHPLC-MS/MS analysis method was performed with MRM mode. The methodological parameters were investigated in detail. The results showed that the linear relationship is good and the detection limit is 0.006 mg/kg. The average recoveries of the two substrates ranged from 83.1% to 113% at low, medium and high mass concentrations. 31 Batches of samples labeled with licorice extracts were tested. Glabridin was detected in 13 batches with the content ranging from lower than LOQ to 944 mg/kg. The study can be used to evaluate the content of the active components of glycyrrhiza extract in cosmetics.

Key words: UHPLC-MS/MS, licorice, glabridin, cosmetic
