建立了人参和黄芪中毒杀芬代表性单体残留量的检测方法.选择7种指示性毒杀芬单体为检测品种,样品用环己烷-丙酮(9∶1,v/v)加速溶剂萃取法提取,经弗罗里硅土固相萃取柱净化后,以气相色谱-电子轰击离子源串联质谱(GC-EI-MS/MS)在多反应监测(MRM)模式下进行测定.在人参和黄芪两种中药材样品基质,0.005、0.01和0.1 mg/kg 3个加标水平条件下,7种毒杀芬单体的回收率为72.4％～105％,相对标准偏差为0.96％～10.4％；方法的检出限(S/N=3)为0.2～1.7 μg/kg,均符合农药残留检测要求.该方法提取效果好,检测灵敏度高,适用于人参和黄芪中7种毒杀芬残留量的检测.
