摘　　要：[目的]建立30%噁嗪草酮悬浮剂高效液相色谱分析方法。[方法]采用内标法,C18、5μm为填料的不锈钢柱和DAD检测器,以乙腈-水(体积比65∶35)为流动相,在220 nm波长下对噁嗪草酮进行分离和定量。[结果]该分析方法的线性相关系数为0.999 9,标准偏差为0.09,变异系数为0.31%,平均回收率为100.1%。[结论]该方法简单可靠,精密度和准确度高,适用于30%噁嗪草酮悬浮剂中有效成分含量的测定。[Aims] The analytical method for determination of oxaziclomefone 30% SC was established. [Methods] The method was developed with internal standard method, 5 μm C,, stainless steel column and DAD detector by UV at wavelength of 220 nm, acetonitrile and water（65 ： 35, by vol） as the mobile phase. [Results] The linear correlation coefficient of standard curve was 0.999 9, the standard deviation was 0.09, the coefficient of variation was 0.31%, and the average recovery was 100.1%. [Conclusions] The method is simple with high precision and accuracy, and can be suitable for determination of the active ingredient of oxaziclomefone 30% SC.
