目的 建立高效液相色谱-串联质谱法同时测定中草药保健食品中15种有机磷和氨基甲酸酯类农药残留.方法 样品经乙腈提取后,高速离心,经分散型固相萃取小柱净化.采用Atlantis C18(2.1 mm× 100 mm,3 μm)柱,以0.1％甲酸-乙腈为流动相,梯度洗脱分离.质谱采用正离子模式(electrospray ionization,ESI+),多反应监测模式(multiple reaction monitoring,MRM)进行检测,基质曲线外标法定量.结果 该方法对15种农药残留的线性范围为0.001～0.1 μg/mL,线性相关系数r≥0.993,加标回收率为82.7％～113.3％,相对标准偏差为2.7％～10.6％,检出限为0.8～24.6 μg/kg.结论 本方法操作简单、快捷,适用于中草药保健食...

Objective To establish a method for simultaneous determination of 15 kinds of organophosphorus and carbamate pesticides in herbal health foods by liquid chromatography-tandem mass spectrometry（LC-MS/MS）. Methods The samples were extracted by acetonitrile, and purified by dispersive solid-phase extraction column after centrifugation with high speed. The analysis was performed on an Atlantis C_（18） column（2.1 mm×100 mm, 3 μm） using 0.1% formic acid-acetonitrile as mobile phase with gradient elution. Mass spectrometry was performed by posi...
