建立了饲料中维吉尼霉素M1的超高效液相色谱-串联质谱(UPLC-MS/MS)分析测定方法.样品用乙腈-0.2% (v/v)甲酸水溶液(8∶2,v/v)超声提取两遍后,通过UPLC-MS/MS进行分析,以BEH C18色谱柱为分析柱,乙腈-0.3% (v/v)甲酸水溶液(35∶65,v/v)为流动相,采用电喷雾电离正离子模式,以多反应监测模式进行定性和定量分析.在0 3~226.6 μg/L范围内线性关系良好(相关系数r=0.999 5).维吉尼霉素M1的检出限和定量限分别为2 μg/kg和7μg/kg,平均回收率为82.6% ~102.7%,相对标准偏差为0.9%~10.5%.结果表明,该方法具有操作简单、准确度和灵敏度高、重现性好的特点,适合用于检测饲料中维吉尼霉素M1的含量.
