[目的]建立烟田样品中残留的阿维菌素和甲氨基阿维菌素苯甲酸盐(以下简称甲维盐)的同时检测方法。[方法]样品经提取后, 采用柱前衍生化法, 再利用高效液相色谱荧光法进行检测。[结果]当阿维菌素和甲维盐的添加质量浓度在0.01~1.00mg/L时, 阿维菌素和甲维盐在烟田样品(包括烟田土壤、烤烟叶、鲜烟叶)中的回收率分别为82.08%~113.63%和83.64%~101.51%, 相对标准偏差分别为0.93%~3.71%和1.49%~5.33%。[结论]该方法稳定可靠, 试验前处理简单, 回收率、精密度和准确性完全达到残留分析要求。

[Aims] It was to develop the simultaneous determination method for abamectin and emamectin benzoate in tobacco fields samples. [Methods] The samples were extrcated by acetonitrile, derivatized before column, and detected by HPLC-FD. [Results] While the adding concentration of abamectin and emamectin benzoate was 0.01-1.00 mg/L, the recovery of abamectin and emamectin benzoate in tobacco sample （soil planted tobacco, flue-cured tobacco, fresh tobacco） was 82.08-113.63% and 83.64-101.51%, the relative standard deviation was 0.93-3.71% and 1.49-...
