摘要:

建立了全自动固相萃取-超高效液相色谱-串联质谱法(UPLC-MS/MS)同时快速测定化妆品中76种糖皮质激素的分析方法。质谱仪采用电喷雾离子化源、正离子多反应检测模式。实验对液态水基类、乳液类、膏霜类三种不同基质类别的化妆品进行考察。样品以饱和氯化钠溶液分散,乙腈进行提取,并选择全自动固相萃取仪进行净化过程。结果表明,76种糖皮质激素的检出限(LODs)为0.004~0.024 μg/g;在10~100 ng/mL范围内线性关系良好(r>0.99);回收率为76.1%~120.8%,相对标准偏差(RSD)为0.4%~13.0%。该方法简便高效,灵敏可靠,适用于各种不同类别的化妆品中76种糖皮质激素的检测。

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.
