将茄果类蔬菜样品用乙腈萃取后，采用全自动凝胶渗透色谱法（GPC）净化-气相色谱-串联质谱法（GC-MS/MS）测定茄果类蔬菜中7种有机磷类杀虫剂（抑菌灵、毒死蜱、氟菌唑、百菌清、噻菌灵、敌菌灵和戊菌唑）残留量。优化的GPC条件为：体积比1：4的丙酮-环己烷混合溶液为洗脱剂，流量为5 mL·min^-1，洗脱时间为8 min，收集时间为6 min；优化的测定条件为：HP-5MS型色谱柱为分离柱，选择电子轰击离子（EI）源和多反应监测（MRM）模式，以环氧七氯为内标物。结果显示：7种有机磷类农药工作曲线的线性范围均为0.05~5.0 mg·L^-1，检出限（3S/N）为0.002 2~0.004 5 mg·kg^-1。按标准加入法进行回收试验，回收率为94.2%~103%，测定值的相对标准偏差（n=6）均小于5.0%。

The sample of solanaceous vegetables was extracted with acetonitrile, and the residual contents of 7 organophosphorus pesticides (i.e., dichlofluanid, chlorphrifos, triflumizole, chlorothalonil, thiabendazole, anilazine, and penconazole) in the purified solution were determined by GC-MS/MS after purification by Autonatic GPC. The optimized conditions of GPC were found:the mixture of acetone and cyclohexane with the volume ratio of 1:4 used as eluent, the flow rate of 5 mL·min^-1, the elution time of 8 min, and the collection time of 6 min. The optimized conditions of determined conditions were found:HP-5MS chromatographic column used as separated column, EI and MRM mode adopted in MS/MS analysis, heptachlor epoxide used as internal standard. As found by results, linearity ranges of the standard curves of 7 organophosphorus pesticides were within 0.05-5.0 mg·L^-1, with detection limits (3S/N) in the range of 0.002 2-0.004 5 mg·kg^-1. Test for recovery was made by standard addition method, giving results in the range of 94.2%-103%, with RSDs (n=6) of the determined values all less than 5.0%.
