摘要:

建立可同时测定化妆品中西咪替丁及雷尼替丁的高效液相色谱-三重四极杆质谱方法。待测样品经甲醇超声提取,经0.2 μm滤膜过滤后进样检测,在优化的色谱、质谱条件下,经ZORBAX SB-Aq色谱柱分离。采用电喷雾离子源在正离子模式下进行多反应监测。用基质匹配外标曲线法进行定量分析。结果表明,西咪替丁、雷尼替丁的检出浓度分别为0.03和0.02 ng/g,在1~100 ng/mL范围内线性关系良好(r >0.999),低、中、高3个质量浓度水平下的样品加标回收率为84.9%~116.2%,RSD不超过5%。建立的方法前处理过程简单,灵敏度、线性、回收率及重复性均满足方法学要求,可同时对化妆品中的西咪替丁和雷尼替丁进行测定。

Abstract:

A high performance liquid chromatography-tandem mass spectrometric method was established for determination of cimetidine and ranitidine in cosmetics. Samples were extracted by methanol ultrasonically, and then filtered through a 0.2 μm membrane. After separated by a ZORBAX SB-Aq column, samples were detected by MRM with electrospray ion source in positive mode. Matrix-matched external standard calibration curves were used for quantitative analysis. The concentration limits of detection of cimetidine and ranitidine were 0.03 and 0.02 ng/g, respectively. In the mass concentration range of 1-100 ng/mL, cimetidine and ranitidine showed good linear relationship with correlation coefficients all above 0.999.The recoveries for cimetidine and ranitidine at three spiked levels were in the range of 84.9%-116.2%, and the relative standard deviations of their recoveries were not more than 5%. This method was able to be applied in determination of cimetidine and ranitidine in cosmetics with simple pretreatment, good linearity and high recovery.

Key words: cosmetics, cimetidine, ranitidine, antihistamine, high performance liquid chromatography-tandem mass spectrometric method
