摘要
本文采用超高效液相色谱-四极杆-静电场轨道阱高分辨质谱技术分析家兔血液中对甲氧基甲基苯丙胺(PMMA)及代谢物。选用Hypersil Gold aQ(2.1 mm×100 mm,1.9μm)色谱柱,流动相为0.1%甲酸水溶液(A)-0.1%甲酸乙腈(B)梯度洗脱,流速0.3m L/min。采用电喷雾离子源ESI,正、负离子模式扫描,根据准分子离子与二级碎片离子判定对甲氧基甲基苯丙胺及其代谢产物,为其药效物质基础研究和打击防范奠定基础。
The high-performance liquid hromatography-quadrupole-electrostatic field orbital well high-resolution mass spectrometry method was developed for the analysis of p-methoxymethamphetamine(PMMA)and its metabolites in rabbit blood.Hypersil Gold aQ(2.1 mm×100 mm,1.9μm)was used as the chromatographic column.The mobile phase was gradient elution with 0.1%formic acid aqueous solution(A)and 0.1%formic acid acetonitrile(B)at a flow rate of 0.3 ml/min.Electrospray ionization(ESI)with positive and negative mode scanning was used to determine p-methoxymethamphetamine and its metabolites based on excimer and secondary fragment ions.PMMA and its metabolites were characterized by high-performance liquid chromatography-high resolution mass spectrometry,which lays a foundation for the study of its pharmacodynamic substance and prevention.
