摘要： A ultra performance liquid chromatography-tandem mass spectrometry method for determination of triazole fungicides in pork, pork liver and pork fat tissue was established. Samples were extracted with acetonitrile , concentrated , and well-mixed with water. The mixed extract was then purified by a PRiME HLB column , and the elution was collected and detected by ultra performance liquid chromatography-tandem mass spectrometry. The matrix-matched standard curve was applied for quantification. The curve was linear in the range of 0. 5 -100 mu g/L with the correlation coefficients of higher than 0. 99. The recoveries ranged from 69.5% to 109.5% at the spiked levels of 2. 0 mu g/kg, 5. 0 mu g/kg and 10. 0 mu g/kg, with relative standard deviations of 0. 4% -10. 8% . The method has many advantages such as simple operation, high sensitivity and good precision, and can largely eliminate the interference in the matrix and is suitable for the residue detection of 21 triazolecompounds in the muscle , liver and fat tissues of animal derived food.
