Abstract: A HPLC-MS/MS method was developed to determine the dinotefuran residue in foods.The test sample was extracted with acetonitrile,and then the extract was dehydrated with anhydrous sodium sulfate.After cleaned up with Envi-Carb/LC-NH2 cartridge and C18 solid-phase extraction cartridge,the analyte was determined with LC-MS/MS using external standard method.This method has good linear correlation(r>0.999) with recovery rate ranges 67% to 90%,detection limit 10 μg/kg,and relative standard deviation(RSD) 3.15% to 8.36%.
