为稳定可靠地分析油茶籽油中多环芳烃，建立了分子印迹固相萃取-气相色谱-串联质谱测定油茶籽油中16种多环芳烃方法。样品经正己烷溶解后，分别采用反相固相萃取HLB小柱、弗罗里硅土小柱和分子印迹固相萃取小柱对16种多环芳烃进行净化。以回收率和基质效应为考察指标评估3种固相萃取柱的净化，在此基础上，对净化液进行低温低速氮吹浓缩，多反应监测扫描模式下进行气相色谱-串联质谱检测，外标法定量。结果表明：分子印迹固相萃取小柱对16种多环芳烃的净化效果最佳；16种多环芳烃在质量浓度1～50 μg/L范围内线性关系良好（R2≥0995 1），检出限为0.01～ 0.20 μg/kg，在2、10 μg/kg和20...
