摘要
目的建立了超高效液相色谱-串联质谱法同时检测唾液中的甲基苯丙胺、氯胺酮和吗啡成分。方法唾液样品经沉淀蛋白后,通过ACQUITY UPLC BEH Phenyl(100mm×2.1mm,1.7μm)色谱柱分离,以0.3%甲酸水和乙腈作为流动相进行梯度洗脱,采用电喷雾离子源正离子(ESI+)多反应监测(MRM)模式进行质谱分析。结果甲基苯丙胺、氯胺酮和吗啡在4μg/L^20μg/L质量浓度范围内线性关系良好;在4μg/L、10μg/L、50μg/L、100μg/L、200μg/L五组添加样本下,添加回收率范围在87%~128%;甲基苯丙胺、氯胺酮、吗啡的检出限(LOD)和定量限(LOQ)均分别为0.2μg/L和4μg/L。结论本方法采用乙腈沉淀蛋白提取,快速、简单、回收率高,适用于同时检测唾液中甲基苯丙胺、氯胺酮和吗啡。
Objective A method of determination of methamphetamine, ketamine and morphine in saliva was established by super high performance liquid chromatography tandem mass spectrometry（UPLC-MS/MS）. Methods The saliva samples after precipitation protein, in the ACQUITY UPLC BEH Phenyl（100 mm×2.1 mm,1.7μm） column chromatography, after the acetonitrile： 0.3% Formic acid solution gradient elution and through the ESI＋ ionization mode MRM analysis and inspection. Results The linearity was estadlished in saliva between 4μg/L and 200μg/L, LOD was 0.2μg/L, LOQ was 4μg/L. the recovery was in the range of 87%-128%. Conclusion The method is simple, rapid and accurate for determination of methamphetamine, ketamine and morphine in saliva.
