摘要:

建立了同时测定化妆品中苯海拉明、曲吡那敏和氯苯那敏等15种禁用物质的超高效液相色谱-串联质谱(UPLC-MS/MS)分析方法。采用Waters Acquity UPLC ?BEH C18色谱柱(1.7 μm×2.1 mm×50 mm)进行分离,以甲醇和乙酸铵-甲酸水溶液为流动相梯度洗脱,流速为0.4 mL/min,进样量为3 μL,在电喷雾正离子模式下(ESI +),采用多反应监测(MRM)模式进行定性和定量。结果表明,所建立的方法在相应的浓度范围内线性关系良好,线性相关系数为0.999 3~0.999 9,加标回收率在87.21%~99.39%(n=3)之间,相对标准偏差为2.28%~5.27%(n=6),检出限为0.004 3~0.239 2 mg/kg,定量限为0.014 3~0.797 2 mg/kg。本方法准确、可靠,适用于化妆品中多种禁用物质的同时测定。

Abstract:

An analytical method of ultra performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS) was developed for the simultaneous determination of 15 prohibited substances (diphenhydramine, tripelennamine, chlorpheniramine, etc.) in cosmetics. The UPLC separation was carried out on a Waters Acquity UPLC? BEH C18 column (1.7 μm × 2.1 mm × 50 mm) by gradient elution using methanol and ammonium acetate-formic acid solution. The flow rate was 0.4 mL/min and the sample injection amount was 3 μL. The electrospray ionization source in positive ion mode (ESI +) was used for qualitative analysis and quantitative analysis of fifteen prohibited drugs in the multiple reaction monitoring (MRM) mode. The established method exhibited a good linear relationship in the corresponding concentration range. The linear correlation coefficient is 0.999 3-0.999 9; the recoveries of standard addition are between 87.21%-99.39% (n=3); the relative standard deviation is 2.28%-5.27% (n=6); the detection limit range is 0.014 3-0.239 2 mg/kg; the limit of quantification range is 0.004 3-0.797 2 mg/kg. The method is accurate and reliable, and is suitable for simultaneous determination of various prohibited substances in cosmetics.
