摘　　要：建立了在同一色谱条件下测定混剂中吡虫啉和噻嗪酮含量的方法。采用150mm×4.6mm(i.d.)XDB-C18柱分离,以甲醇-乙腈-水(体积比60∶10∶30)为流动相,在250nm检测波长下,以保留时间定性确证,峰面积外标法进行定量分析。结果表明:吡虫啉和噻嗪酮的线性相关系数分别为0.997和0.994;变异系数分别为1.24%和3.06%;平均回收率分别为98.45%和97.52%。A HPLC method for the determination of imidacloprid and buprofezin EC was developed. The HPLC conditions were XDB-C18 column, methanol-acetonitrile-water （60：10：30 by vol） as mobile phage, and detection wave length at 250 nm. The results demonstrated that the correlation coefficients of imidacloprid and buprofezin were 0.997 and 0.994. The variation coefficients were 1.24% and 3.06%. The average recoveries were 98：45% and 97.52%. The method is simple, rapid, accurate and suitable for analysis of this kind of multiplex confected preparation.
