摘要

目的 探讨应用高效液相色谱串联质谱法(HPLC-MS/MS)测定血浆中西酞普兰药物浓度的方法。  方法 设立色谱柱为Agilent-ZORBAX-C8柱;流动相:乙腈-0.1%甲酸水溶液(60:40);流速:0.5 ml/min;柱温:20 ℃;质谱条件为电喷雾电离源(ESI),以多反应监测(MRM)方式进行检测,用于定量分析的反应离子为m/z 325.1 262.1(西酞普兰)和m/z 256.2 67.1(苯海拉明,内标)。 结果 西酞普兰在0.5~100 ng/ml范围内线性关系良好(r=0.9979);西酞普兰的日内、日间精密度RSD均<10%。 结论 该方法分析速度快,专属性强,灵敏度高,可作为西酞普兰的血浆药物浓度检测方法。

Abstract

Objective To establish an HPLC-MS/MS method for determination of the content of citalopram in human plasma.  Methods The chromatographic column was Agilent-ZORBAX-C8 (4.6×150 mm,5 μm), from Agilent Company, The mobile phase was methyl cyanides-0.1%formic acid(60∶〖KG-*2〗40). The flow rate was 0.5 ml/min and m/z 256.2167.1. The column temperature was 20 ℃. Electrospray ionization(ESI) source was applied and multi-reaction monitoring(MRM) mode with the transitions of m/z 325.1262.1(for citalopram) and m/z 256.2167.1 (for diphenhydramine internal standard)was used.  Results The assay linearity of citalopram was confirmed over the range 0.5-100 ng/ml ( r =0.9979). The intra-and inter-day precision (RSD) was less than 10%.  Conclusions The method is proved to be quick,specific,sensitive and accurate,which can be used for the determination of citalopram in plasma.
