摘　　要：采用反相高效液相色谱法,Lichrospher-C18色谱柱,以甲醇-水(体积比97∶3)为流动相,在同一色谱条件下对7.5%吡虫啉和氰戊菊酯复配乳油有效成分进行同时分析测定。吡虫啉和氰戊菊酯的保留时间分别为2.1min和4.2min,变异系数(n=6)分别为0.623%和0.541%,平均回收率分别为100.4%和100.6%,线性相关系数分别为0.9996和0.9997。High performance chromatography was adopted for the separation and determination of imidacloprid and fenvalerate in mixed emulsion on the Lichrospher-C18 column with methanol and water （97：3, by vol） as mobile phase and UV detector. Under the selected conditions, the retention times of imidacloprid and fenvalerate were 2.1 min and 4.2 rain respectively. RSD＇s（n=6） for imidacloprid and fenvalerate were found to be 0.623% and 0.541%. And the average recoveries were 100.4% and 100.6%. The linear correlation coefficients were 0.9996 and 0.9997 respectively.
