　　建立了大白菜、豇豆、花菜、番茄等蔬菜中氟啶虫酰胺、氯虫苯甲酰胺、甲氧虫酰肼、氟苯虫酰胺、虫螨腈和虱螨脲等6种杀虫剂残留的液相色谱检测方法。蔬菜经乙腈高速匀浆提取，过NH 2-SPE小柱净化，再用甲醇定容。以甲醇＋乙腈＋水为流动相，利用C 18柱和紫外检测器(检测波长：265,254,230 nm)对待测组分进行分离和测定。结果表明：添加浓度在0.1,0.5,1.0 mg/kg时，蔬菜中氟啶虫酰胺、氯虫苯甲酰胺、甲氧虫酰肼、氟苯虫酰胺、虫螨腈和虱螨脲的平均添加回收率在88.9%～119.2%之间，相对标准偏差(RSD)为0.26%～11.56%，仪器的最小检出量为1 ng，这6种农药在样品中的最低检测浓度为0.05 mg/kg。

A high-performance liquid chromatography (HPLC) method was developed for the determination of flonicamid, chlorantraniliprole, methoxyfenozide, flubendiamide, chlorfenapyr and lufenuron residues in vegetables such as Chinese cabbage, cowpea, cauliflower and tomato. The vegetable samples were extracted with acetonitrile, cleaned up with NH 2-SPE columns, and condensed to dry. Determinations of the analytes were completed by HPLC with DAD at 265, 254 and 230 nm. The results showed that the fortified recoveries of these six insecticides in vegetable samples were in the range of 88.9%-119.2%, with the relative standard deviations of 0.26%-11.56%. The limit of detection was 1 ng, and the limits of quantification of the six insecticides were 0.05 mg/kg in these vegetable samples.
