摘　　要：建立了高效液相色谱法同时测定24%甲氧·虫螨腈悬浮剂中有效成分的分析方法。使用乙腈+水作为流动相,二极管阵列检测器和C_(18)不锈钢色谱柱,在240 nm波长下对试样中甲氧虫酰肼和虫螨腈同时进行分离和定量分析。该方法中甲氧虫酰肼和虫螨腈线性相关系数R2分别为1.0000和0.9999;相对标准偏差分别为0.38%和0.25%;平均回收率分别为99.79%、100.2%。该方法便捷高效,分离效果好,精密度和准确度高,各项分析指标均符合要求,可适用于制剂中甲氧虫酰肼和虫螨腈的定量分析。A high-performance liquid chromatography(HPLC)method for the simultaneous determination of the active ingredients in 24%methoxyfenozide·chlorfenapyr SC was established.The separation and quantitative analysis of methoxyfenozide and chlorfenapyr in the samples were carried out at 240 nm using a C_(18) stainless steel column with a mobile phase of acetonitrile+water.and detection via a photodiode array detector.The linear correlation coefficients R2 for methoxyfenozide and chlorfenapyr were 1.0000 and 0.9999,respectively.The relative standard deviations were 0.38%and 0.25%,while the average recoveries were 99.79%and 100.2%,respectively.The method demonstrated high convenience,efficiency,precision and accuracy,achieving good separation and meeting all analytical requirements.It is suitable for the quantitative analysis of methoxyfenozide and chlorfenapyr in preparations.
