摘要
建立了阿维菌素在土壤中的残留分析方法。以乙腈为提取溶剂，经N-甲基咪唑和三氟乙酸酐衍生化后，用高效液相色谱-荧光检测器在激发波长为365nm、发射波长为470nm处测定。方法添加回收率为89．98-93．20％，变异系数为2．45-7．98％，检测限为0．0004mg／kg。
A method was developed to determine residue of avermectin in soil . The soil samples were extracted by acetonitrile. After derivatization with N -methylimidazole and trifluoroaeetic anhydride, avermectins were determined by HPLC with fluoresoence detector（λex = 365nm, λem = 470nm ）. The average recovery of avermectin was in the range of 89.98% - 93.20%, the coefficient of variation was in the range of 2.45% -7.98% and the limit of detection was 0.0004mg/kg.
