Abstract:

An analytical method was established for the determination of Glycyrrhizae functional components (liquiritin and glycyrrhizic acid), Ginseng functional components (ginsenoside Rg1, ginsenoside Rb1, ginsenoside Re) and Scutellariae functional components (baicalin) in facial mask cosmetics with ultra-high performance liquid chromatography triple quadrupole mass spectrometry (UHPLC-MS/MS). This method was used to monitor the risk of 20 batches of samples sold on the market. The samples were extracted by ultrasonic method using 0.1% formic acid in methanol. The mobile phase was 0.1% formic acid aqueous solution-acetonitrile solution, and the gradient elution was carried out. The samples were separated on the ACQUITY UPLC HSS T3(2.1 mm×100 mm, 1.8 μm) column and detected by UHPLC-MS/MS negative ion mode. At the same time, the pretreatment conditions and UHPLC-MS/MS conditions were optimized and the method was verified. The results show that the method shows good linearity in the mass concentration range of 0.25-100 ng/mL for liquiritin and baicalin, and 0.50-200 ng/mL for ginsenoside Rg1, ginsenoside Rb1, ginsenoside Re and glycyrrhizic acid, with R no less than 0.998. The limits of detection are in the range of 0.41-6.4 μg/kg (S/N=3). The average recoveries in the sample matrix of facial masks are from 95.9% to 109.1%, with the relative standard deviations (RSDs) less than 4.9% (n=6). This method is suitable for the determination of ginseng functional components in the ginseng cosmetics.
