摘要:

建立了基于液相色谱串联质谱的分析方法,用于同时测定四种不同基质化妆品中7种特应性皮炎治疗药物。待测样品经80%甲醇涡旋分散、超声提取后,过0.22 μm PTFE滤膜,所得滤液采用Kinetex® C18 (2.6 μm × 2.1 mm × 100 mm)分离,0.1%甲酸溶液-乙腈流动相体系梯度洗脱,在电喷雾离子源(ESI)及多反应监测模式(MRM)对目标化合物进行测定。结果表明,7种特应性皮炎治疗药物在各自线性范围内具有良好的线性关系(r>0.997),检出限为0.8~171 μg/kg;7种药物在四类不同基质化妆品中回收率在86.5%~109.7%范围内,相对标准偏差(RSD)为0.13%~5.4%。该方法具有操作简便快捷,定性定量可靠,适用于测定化妆品中7种特应性皮炎治疗药物,能够为化妆品风险监测和标准制修订提供技术支撑。

Abstract:

A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been established for the simultaneous determination of seven atopic dermatitis treatment drugs in 4 different cosmetic matrices. Following vortex dispersion and ultrasonic extraction with the test sample using 80% methanol, the mixture was filtered through a 0.22 μm PTFE membrane. Chromatographic separation of the filtrate was achieved on a Kinetex® C18 (2.6 μm×2.1 mm×100 mm) column, utilizing a gradient elution system consisting of 0.1% formic acid in water and acetonitrile as the mobile phase. The determination of target compounds was performed using an electrospray ionization source (ESI) in multiple reaction monitoring mode (MRM). The results show that the seven atopic dermatitis treatment drugs exhibit good linear relationships within their respective linear ranges (r>0.997), with limits of detection (LODs) ranging from 0.8 to 171 μg/kg. The recovery rates of the seven drugs in the 4 cosmetics matrices range from 86.5% to 109.7%, with relative standard deviations (RSD) of 0.13% to 5.4%. This method is simple, rapid, and provides reliable qualitative and quantitative analysis, making it highly suitable for the determination of these drugs in cosmetics. Furthermore, it can provide valuable technical support for cosmetic risk monitoring and standard revisions.
