摘要:

建立了超高效液相色谱-质谱法(UPLC-MS/MS)测定化妆品中14种非法添加噻嗪类药物的分析方法。化妆品样品经甲醇超声提取,提取液在0.2%甲酸水溶液-甲醇的流动相体系下经Agilent RRHD Eclipse Plus ZorbaxC18(3.0 mm×100 mm,1.8 μm)色谱柱梯度洗脱分离。质谱分析采用电喷雾负离子模式下多反应监测(MRM)方式,基质匹配外标法定量。以水剂、凝胶、乳液、膏霜、粉剂及精油为代表基质,14种噻嗪类药物在各自的质量浓度范围内线性关系良好,相关系数(r2)为0.990 7~0.999 6,检出限为0.004 0~0.100 0 μg/g,定量限为0.008 0~0.400 0 μg/g。低、中、高3个不同质量浓度加标水平下,水剂、凝胶、乳液、膏霜、粉剂及精油样品平均回收率为85.9%~114.4%;相对标准偏差为0.8%~11.8%。该方法前处理高效、灵敏度高、重复性好、定性可靠、定量准确,适用于不同类型化妆品中14种噻嗪类药物的快速定性定量分析。

Abstract:

A new method for the simultaneous and rapid determination of 14 thiazides in cosmetics by ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The cosmetic samples were dispersed with methanol and ultrasonic extraction, and the filtrate was analyzed by a Agilent RRHD Eclipse Plus Zorbax C18 chromatographic column (3.0 mm×100 mm, 1.8 μm), with 0.2% formic acid aqueous solution and methanol as mobile phases under gradient elution. The condition of mass spectrometry was negative ions scanning with multiple reaction monitor mode (MRM) under the electrospray ionization source. For the representative matrix samples (including water aqua, gel, lotion, cream, powder and essential oil), thiazides tested show the correlation coefficients for linear calibration curves are in the range of 0.990 7-0.999 6 in the corresponding concentration range. The limits of detections (LODs) of 14 thiazides are in the range of 0.004 0-0.100 0 μg/g, and the limits of quantitations (LOQs) are in the range of 0.008 0-0.400 0 μg/g. The recoveries of low, medium and high concentrations ranged 85.9%-114.4%, with the relative standard deviations (n=6) ranged 0.8%-11.8%. The established method is simple, effective, high sensitive, good repeatability, qualitatively reliable, quantitatively accurate, and is suitable for the determination of 14 thiazides in different matrixes of cosmetics.
