摘要: 建立了同时检测化妆品中21种非甾体抗炎药的UHPLC-MS/MS方法。选用膏霜、面膜、凝胶、液体水基类样品为化妆品代表性基质,样品采用甲醇或0.3% (V/V)甲酸-甲醇进行超声辅助液液萃取。使用ACQUITY UPLC BEH C18 (1.7 μm,2.1 mm×150 mm)色谱柱进行分离,分别以0.1% (V/V)甲酸-水和乙腈作为水相和有机相进行梯度洗脱,在多反应监测模式下进行检测。对样品前处理条件和色谱、质谱条件进行了系统性考察。结果表明,20种化合物的线性范围为5~50 μg/L,罗非昔布线性范围为10~100 μg/L,均线性相关系数良好(r>0.99)。低、中、高三个浓度水平的加标回收率范围为72.1%~117.3% (n=6),相对标准偏差RSD范围为0.6%~9.7%。该方法操作简便、准确性高、灵敏度好,适用于化妆品中非甾体抗炎药的检测,能够为化妆品中行为的监管提供技术支撑。

Abstract:

A method was developed for the determination of 21 nonsteroidal anti-inflammatory drugs (NSAIDs) in cosmetics by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Four kinds of cosmetics such as cream, facial mask, gel and toner were selected as representative matrix. The sample pretreatment conditions, chromatography and mass spectrometry conditions were systematically investigated. At first, the cosmetic samples were extracted by methanol for cream, gel, toner matrix, and methanol containing 0.3% (V/V) formic acid for facial mask matrix by ultrasonic-assisted liquid-liquid extraction. Then they were separated on an ACQUITY UPLC BEH C18 column (1.7 μm, 2.1 mm×150 mm) by gradient elution. Aqueous containing 0.1% (V/V) formic acid and acetonitrile were used as mobile phases. The flow rate was 0.3 mL/min and injection volume was 5 μL. Finally, samples were detected with multiple reaction monitoring (MRM) scanning mode. The results show a good linearity in the concentration range of 10-100 μg/L for rofecoxib and 5-50 μg/L for other NSAIDs. The spiked recoveries at the low, medium, and high levels range from 72.1% to 117.3%, with the RSD ranging from 0.6% to 9.7% (n=6). This method has the characteristics of simple operation, high accuracy, and good sensitivity. It is suitable for the detection of NSAIDs in cosmetics, and provides a technical support for the supervision in cosmetics.
