摘要: 目的 建立一种QuEchERS-高效液相色谱-串联质谱测定牛奶中6种喹诺酮类兽药残留的方法。方法 样品经含1%甲酸的乙腈溶液提取后,用PSA粉末净化,经C18色谱柱分离,三重四级杆质谱检测。结果 6种喹诺酮在浓度2.0~100.0 ng/mL范围内线性良好,相关系数>0.999,检出限范围为0.222~0.439 μg/kg,定量限范围为0.739~1.464 μg/kg,加标回收率为76.27%~97.84%,相对标准偏差为3.22%~8.77%。结论 该方法操作简便、快速、准确,可作为牛奶中喹诺酮药物残留的定量检测方法。

Abstract: Objective To develop a methodfor the determination of six quinolones residues in milk by QuEchERS-high-performance liquid chromatography-tandem mass spectrometry. Methods The sample was extracted with acetonitrile containing 1% formic acid,purified with PSA powder,separated by C18 column,and detected by triple quadrupole mass spectrometry. Results The six quinolones showed good linearity in the concentration range of 2.0-100.0 ng/mL,the correlation coefficients were>0.999,the detection limits were 0.222-0.439 μg/kg,the quantitative limits were 0.739-1.464 μg/kg,the recoveries were 76.27%-97.84%,and the relative standard deviations were 3.22%-8.77%. Conclusion The method is simple,rapid and accurate,and can be used for the quantitative determination of quinolone residues in milk.
