| Abstract: | A method to detect chlorpromazine residues in fish products was developed by using high performance liquid chromatography-tandem mass spectrometry(HPLC/ MS/MS).Chlorpromazine was extracted with acetonitrile from the test tissue.The extract was cleaned up and concentrated on an Oasis MCX cartridge,eluted by basic methanol and then analyzed by HPLC-MS/MS.The quantification was performed with internal standard method,with D6-Chlorpromazine as internal standard.The average recoveries were 90.1%-95.1%(Intraday) in the spiked range of 1-25 μg/kg in fish.The relative standard deviations were 2.5%-5.7%(Intraday).The limits of quantification(S /N >10) were 1.0 μg/kg and the limits of detection(S /N >3) were 0.5 μg/kg.Results indicated that the method used was easier,faster and more accurate. |
