摘要： In this work, a convenient, sensitive method for simultaneous monitoring of malachite green, leucomalachite green in tilapia samples was developed by ultra-high -performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The tilapia samples were extracted by acetonitrile, separated withacetonitrile-5mmol/L ammonium acetate as mobile phase, and then detected under ESI+ mode.The method showed a good linearity for all the analysts over the range of 0.1-100 mu g kg(-1) with r(2)>= 0.998. And the detection limits both were 0.10 mu g kg(-1) for Malachite green and leucomalachite green. Tests for recovery were made by addition of standards at four different concentration levels (0.5.2.0.10.0.20.0 mu g kg(-1)) to the blank sample. The recoveries of the four spiked concentrations were ranged from 81.5% to 104%, with the relative standard deviations lower than 5%. The sensitivity, accuracy and precision of this method were able to meet the requirements for malachite green and leucomalachite green residue analysis.
