[目的]研究苯嘧磺草胺颗粒剂中有效成分含量的定量分析方法。[方法]采用高效液相色谱法,使用C18柱,以乙腈-三氟乙酸水溶液为流动相,在254 nm波长下进行测定。[结果]方法的线性相关系数为1.0000,定量检测限(LOQ)为61.4 mg/L,最佳称量范围0.01～0.25 g,标准偏差为0.077 1,变异系数为0.396%,回收率为99.9%～102.7%。[结论]方法快速、准确,适用于苯嘧磺草胺颗粒剂的定量分析。
[Objective] The research aimed to study the quantitative analysis method of the content of the active ingredient in saflufenacil granules. [Method] The determination was carried out by high performance liquid chromatography with a C18 column using acetonitrile-trifluoroacetic acid as mobile phase at 254 nm. [Result] The linear correlation coefficient of the method was 1.0000, LOQ was 61.4 mg / L, the best weighing range was 0.01-0.25 g, the standard deviation was 0.077 1, the coefficient of variation was 0.396% and the recovery was 99.9% ~ 102.7%. [Conclusion] The method is rapid, accurate and suitable for the quantitative analysis of saflufenacil granules.
