摘要: 目的:建立人血浆中尼群地平的HPLC-MS/MS定量分析方法。方法: 血浆样品经液-液萃取预处理,色谱柱为Eclipse C18(4.6 mm×150 mm, 5 μm),流动相为乙腈-水梯度洗脱,采用三重四级杆质谱仪进行多反应监测方式(MRM),电喷雾离子源,对所建立方法进行了较全面的验证。结果: 线性范围为 0.1~50.1 ng/mL,最低定量浓度为 0.1 ng/mL,提取回收率分别为 84.1%、94.1%和 87.0%,且稳定性良好。结论:该方法操作简便、快速、灵敏度高,可用来进行尼群地平的临床血药浓度测定和药动学研究。

Abstract: AIM: To establish HPLC-MS/MS quantitative analysis method for the determination of nitrendipine in plasma.METHODS: The plasma samples were pretreated with liquid-liquid extraction.HPLC analysis was carried out on a Eclipse C18(4.6 mm×150 mm,5 μm)with a mobile phase consisting of acetonitrile and water gradient elution.Detection was carried out on a triple quadrupole tandem mass sepectrometer by multiple-reaction monitoring and an electrospray ionization source was employed as the ionization source.The method was fully validated.RESULTS:The linear range was 0.1-50.1 ng/mL and the determination limit was 0.1 ng/mL.The extraction recovery were 84.4%,94.1% and 87.0%.The assay of stability was well.CONCLUSION: The method is simple, rapid, high sensitivity,can be used for nitrendipine clinical blood concentration determination and pharmacokinetics study.
