摘　　要：本文采用高效液相色谱法建立了一种测定33%苯醚甲环唑·萎锈灵悬浮种衣剂中有效成分含量的分析方法。以乙腈、水和醋酸(80∶19.5∶0.5,V/V/V)为流动相,用紫外检测器定量测定混剂中苯醚甲环唑和萎锈灵的含量。本方法的线性相关系数均为0.9997,R^(2)均大于0.999;平均回收率分别为100.6%和100.4%;标准偏差分别为0.0241%、0.1011%;变异系数分别为0.758%和0.334%。该方法精密度和准确度高,线性相关性好,适用于33%苯醚甲环唑·萎锈灵悬浮种衣剂的定量分析。This study aimed to establish an analytical method for the determiniation of the content of active constituents in 33%difenoconazole·carboxin FSC by HPLC.Acetonitrile,water and acetic acid(80:19.5:0.5,V/V/V)were used as the mobile phase,and a UV detector was used to quantitatively determine the content of difenoconazole and promethrin in the mixture.Both of difenoconazole and carboxin of the linear correlation coefficients were 0.9997,greater than 0.999.The average recoveries of this method were 100.6%and 100.4%,the standard deviations were 0.0241%and 0.1011%,the coefficient of variation were 0.758%and 0.334%,respectively.The method could be used for the quantitative analysis of 33%difenoconazole·carboxin FSC with high precision and accuracy,good linear correlation.
