| Abstract: | Objective] The study aimed to build the detection method for residues of diclazuril and investigate the depletion of diclazuril in chicken eggs.Method] The material was extracted by mixed solution of acetonitrile and ethyl-acetate,the extracts were dried by nitrogen gas,redissolved in acetonitrile,filtered through 0.22 μm micropore film and directly injected into the LC-MS/MS system.Result] The calibration curves were linear(r2>0.99)in the range of 1-50 μg/kg.Limit of detection(LOD)and limit of quantitation(LOQ)were 0.2 μg/kg and 0.5 μg/kg.Conclusion] The method was simple and accurate enough to determine residues of diclazuril in chicken eggs. |
