中文摘要: 该文建立固相萃取结合高效液相色谱-串联质谱技术(solid phase extraction-high performance liquid chromatography-tandem mass spectrometry,SPE-HPLC-MS/MS)测定蜂胶中氯霉素残留的检测方法。蜂胶样品经乙腈溶解,氢氧化钙溶液沉淀杂质,Bond Elut Plexa固相萃取柱(6mL,200mg)净化,Kinetex C18色谱柱(50mm×2.1mm,2.6μm)分离,以水-乙腈为流动相梯度洗脱分离,在负模式下,采用多反应监测(multiple reaction monitoring,MRM)模式检测,内标法定量。结果表明,氯霉素在 0.1 μg/L~500.0 μg/L 范围内线性关系良好(R2>0.99),检出限为 0.4 μg/kg,定量限为1.0 μg/kg。氯霉素在蜂胶样品中添加水平为1、2、10 μg/kg时平均回收率为93.2%~103.4%,日内和日间相对标准偏差分别为0.98%~3.95%和0.93%~5.37%(n=5)。该方法操作简便,耗时短,灵敏度高,稳定性好,适用于蜂胶中氯霉素残留筛查检测及定量分析。
