Abstract
目的:建立一种高效液相色谱法( high performance liquid chromatography,HPLC),用来测定人头发中的喹硫平浓度。方法色谱柱使用Inertsil ODS-C18柱(4.6 mm ×150 mm,5μm),流动相为0.01 mol/L醋酸铵-甲醇(32︰68),流速为1.0 mL/min,柱温40℃,检测波长为254 nm,以正已烷为萃取剂,建立HPLC法。结果喹硫平在5~200 ng/mg范围内峰面积与浓度呈良好线性关系,萃取回收率>75.0%,方法回收率在95.0%~105.0%之间,日内和日间精密度均<10.0%,符合生物样品分析要求。结论本研究建立了测定人头发中喹硫平浓度的HPLC法,该方法操作简单,结果灵敏、准确,具有一定的应用价值。
