[目的]建立50%嘧菌酯水分散粒剂高效液相色谱分析方法。[方法]以乙腈-水-甲酸为流动相,使用ODS-C18反相柱,在225 nm检测波长下,对样品进行分离检测。[结果]嘧菌酯的标准偏差为0.1877,变异系数为0.37%,平均回收率为100.2%,线性相关系数为0.9998。[结论]该方法操作简便快捷,准确度和精密度高,线性相关性好。 [Objective] To establish a 50% azoxystrobin water dispersible granule HPLC method. [Method] With acetonitrile - water - formic acid as mobile phase, the sample was separated and detected at the detection wavelength of 225 nm using ODS-C18 reverse phase column. [Result] The standard deviation of azoxystrobin was 0.1877, the coefficient of variation was 0.37%, the average recovery was 100.2% and the linear correlation coefficient was 0.9998. [Conclusion] The method is simple, rapid, accurate and precise, and has good linear correlation.
