摘 要:目的建立QuEChERS EMR-Liqid-超高效液相色谱-串联质谱法测定动物源食品中的安眠酮残留的分析方法。方法样品用1%甲酸乙腈提取,经过QuEChERS EMR-Lipid萃取净化后,采用在电喷雾正离子模式下以质谱多反应监测(multiple reaction monitoring,MRM)方式检测。结果安眠酮在0.1~100 ng/m L浓度范围内线性良好,相关系数为0.9997,方法检出限0.03μg/kg,定量限为0.1μg/kg,在0.1、0.2和0.5μg/kg 3个加标水平下的回收率为85.5%~98.6%,相对标准偏差(relative standard deviations,RSDs)为2.07%~4.56%。结论该方法简便快捷、灵敏可靠,适用于动物源食品中的安眠酮药物的快速检测。Objective To establish a method for determination of methaqualone residues in animal-derived food by Qu ECh ERS EMR-Liqid-ultra performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).Methods Samples were extracted with acetonitrile with 1% formic acid,then purified by Qu ECh ERS EMR-Lipid extraction column.The UPLC-MS/MS(ESI+) with multiple reactions monitoring(MRM) was used for detection.Results Methaqualone had a good linear relationship in the range of 0.1-100 ng/m L,and the correlation coefficient was 0.9997.The limit of detection was 0.03 μg/kg,and the limit of quantization was 0.1 μg/kg.The recoveries were ranged from 85.5%-98.6% for methaqualone at 3 spiked levels of 0.1,0.2 and 0.5 μg/kg.The relative standard deviations(RSDs) were from 2.07%-4.56%.Conclusion The method is easy,rapid,accurate and sensitive,which is suitable for detecting methaqualone in animal-derived food.
