Abstract：An efficient ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was established for the simultaneous analysis of residues of 4 antiviral drugs ( amantadine, rimantadine, morpholine, and memantine) in fish and shrimp. Samples were extracted with 1% trichloroacetic acid and 1% acetic acid acetonitrile (1∶9, V/V), purified by PSA powder, C18 powder, neutral alumina dispersed solid phase extraction. Quantifification of the analytes was achieved by UPLC-MS/MS using the internal standard method. The limit of detection (LOD) and limit of quantifification (LOQ) of the method were lower than 0.8 μg/kg and 1.0 μg/kg for all the antiviral drugs, respectively. The average recoveries of 4 antiviral drugs in blank fish and shrimp at spiked levels of 1.0, 10.0, and 50.0 μg/kg ranged from 86.0% to 98.5%, with relative standard deviation (RSD) of less than 8%. The method is featured by small matrix interference, high sensitivity and good recovery rate, and can be used for residue detection of antiviral drugs in daily fish and shrimp samples.
