摘要
本文报道用高效液相色谱柱后衍生化检测肉鸡肌肉、肝脏和脂肪组织中莫能菌素和盐霉素的残留。肉鸡肌肉、肝脏和脂肪组织经异辛烷提取 ,用硅胶柱净化分离 ,洗脱液浓缩后用甲醇 /水溶解。以甲醇 /冰乙酸 /水 ( 94 0 / 30 / 30 ,v/v)作为流动相 ,香草醛为衍生剂 ,用RP C18柱在可见波长52 0nm处检测。将莫能菌素和盐霉素分别以 0 10 ,0 2 0 ,0 4 0和 0 2 0 ,0 4 0 ,0 80 μg/ g分别添加到空白肉鸡组织中 ,测得莫能菌素和盐霉素在肌肉、肝脏和脂肪组织中的平均回收率分别为 97 7%、91 1%、92 1%和 94 1%、85 4 %、90 7% ,变异系数范围在 2 7%~ 16 8%之间。用该方法测定肉鸡组织中莫能菌素和盐霉素残留的最低检测限分别为 0 0 5μg/ g和 0 1μg/ g。
