摘  要：
采用液相色谱-串联质谱仪(LC-MS/MS)建立了植物源性食品中氟吡菌胺、烯肟菌胺、氯虫苯甲酰胺残留的定量分析方法,样品经过乙腈涡旋提取后,无水MgSO4、PSA和C18分散固相萃取净化,LC-MS/MS检测。结果表明:在2—100μg/L的线性范围内,氟吡菌胺、烯肟菌胺、氯虫苯甲酰胺的峰面积与其浓度呈良好线性关系,方法检出限为2μg/kg;在水稻、西瓜、青菜、番茄和黄瓜5种基质中,10μg/kg、20μg/kg和40μg/kg三个添加水平下,氟吡菌胺、烯肟菌胺、氯虫苯甲酰胺回收率为88. 2%—107. 6%,相对标准偏差为1. 2%—8. 2%。该方法可以满足植物源性食品中氟吡菌胺、烯肟菌胺、氯虫苯甲酰胺残留检测的需要。

摘  要：
The liquid chromatography-tandem mass spectrometry( LC-MS/MS) was developed to analyze fluopicolide,fenaminstrobin and chlorantraniliprole residues in plant foods. After extracted from sample with acetonitrile and cleaned up by dispersive solid-phase extraction with PSA and C18,fluopicolide,fenaminstrobin and chlorantraniliprole was determined by LC-MS/MS. As a result,The calibration curves showed good linearity over the concentration range of 2. 0—100 μg/L with correlation eoefficients above 0. 998,and the limits of determination( LOD) was 2. 0 μg/kg. The recoveries of fluopicolide,fenaminstrobin and chlorantraniliprole residues in plant foods were in the range of 88. 2% —107. 6% at three spiked levels( 10 μg/kg,20 μg/kg,40 μg/kg),and the relative standard deviations were 1. 2% —8. 2%.
