摘要:

建立了同时测定2种不同基质类型化妆品中非法添加38种抗感染禁用药的超高效液相色谱-串联质谱方法。样品经溶剂提取后,采用Waters Acquity BEH C18(50 mm×2.1 mm,1.7 μm)色谱柱,流动相A为0.1%乙酸铵缓冲液(pH=4.0),流动相B为0.1%甲酸甲醇,梯度洗脱;使用三重四极杆质谱多反应监测模式(MRM)检测,以保留时间和相对离子丰度定性,外标法定量。结果表明,氯霉素在质量浓度100~1 000 μg/L范围内,其余37种抗感染药在质量浓度15~150 μg/L范围内均呈现良好的线性关系,相关系数均大于0.99;方法检出限和定量限分别为0.3~240.4 μg/kg和1.1~801.2 μg/kg。3个不同浓度加标水平下,38种抗感染化合物的加标回收率为79.0%~119.8%,相对标准偏差为0.3%~9.7%(n=6)。该方法准确、灵敏、快速,适用于水剂和膏霜化妆品中38种抗感染药的同时测定。

Abstract:

An ultra high performance liquid chromatography-tandem mass spectrometric method was established for the determination of 38 forbidden anti-infective drugs in 2 matrixes of cosmetics. The cosmetic samples were extracted with solvent and performed on a Waters BEH C18 (2.1 mm×100 mm, 1.7 μm) column with binary mobile phase consisting of 0.1% ammonium acetate pH=4.0 (solvent A) and 0.1% formic acid methanol solution (B) with gradient elution. Samples were analyzed by electronic spray ionization under a positive ion or negative ion mode with multiple reaction monitoring (MRM), and then quantified by an external standard curve. The calibration curve of chloramphenicol is linear within the range of 100-1 000 μg/L and the calibration curves of the other 37 target compounds are linear within the range of 15-150 μg/L with the correlation coefficients above 0.99. The limits of detection (LOD) and limits of quantitation (LOQ) are in the ranges of 0.3-240.4 μg/kg and 1.1-801.2 μg/kg, respectively. The recoveries for 38 prohibited anti-infective drugs at three spiked levels are in the range of 79.0%-119.8% with the relative standard deviations (RSD) of 0.3%-9.7%(n=6). The method is simple, rapid and accurate, and quite suitable for the simultaneous determination of illegally added anti-infective drugs in aqueous and cream cosmetics.
