Abstract：To establish a gas chromatography-tandem mass spectrometry （GC-MS/MS） method for the determination of five new pesticide residues （2，6-diisopropylnaphthalene， flumethrin， benzpyrimoxan， flupyrimin，and sedaxane） in animal-derived foods.The sample pretreatment procedures along with chromatographic and mass spectrometric conditions were optimized. The samples were extracted using acetonitrile/acetone （1：1， u/ν ，containing 1% acetic acid） via ultrasonic extraction， purified by dispersive solidphase extraction （d-SPE）， and analyzed by GC-MS/MS.The five pesticides exhibited good linearity in the concentration range of 0.0004-0.1000μg/mL ，with correlation coefficients . The quantitation limits ranged from 0.4μg/kg to 87.7μg/kg ：Therecoveries at three different spiked concentration levels were between 73.23% and 111.92% ，and the relative standard deviations （RSD） for precision were within 15% 0 5）.The method is rapid and simple in sample pretreatment，and sensitive and accurate in detection. Itis suitable for the determination ofresidues of the five new insecticides and fungicides in animal-derived foods.
