摘要:

建立了一种超高效液相色谱串联质谱法同时测定化妆品中94种非法添加物的方法。化妆品试样采用70%乙腈水超声提取,以0.1%甲酸乙腈溶液-0.1%甲酸水溶液、5 mmol/L乙酸铵水溶液作为流动相,经CORTECS?UPLC?C18色谱柱(2.1 mm×100 mm,1.6 μm)进行分离,通过超高效液相色谱串联质谱测定。结果表明,方法线性良好,相关系数均大于0.995,方法定量限为0.025~0.1 μg/g,添加平均回收率为51.1%~129.3%,相对标准偏差为1.8%~19.0%。

Abstract:

A method for simultaneous determination of 94 kinds of illegally added compounds in cosmetics by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The cosmetic samples were extracted with the mixed solvent of 70% acetonitrile-water under ultrasonic assistance. Then the components in the purified extract were separated by CORTECS?UPLC?C18 column (2.1 mm×100 mm, 1.6 μm) with 0.1% formic acid/acetonitrile solution-0.1% formic acid and 5 mmol/L ammonium acetate as mobile phase, and then detected by UPLC-MS/MS. The method showed that good linearity was obtained with correlation coefficients higher than 0.995. The range of the limit of quantitation for this method was 0.025-0.1 μg/g. The spiked recovery was in the range of 51.1%-129.3%, and the RSD was 1.8%-19.0%.
