[目的]建立一种高效液相色谱测定烯肟菌胺·噻呋酰胺悬浮剂的分析方法。[方法]采用反相高效液相色谱法,以反相ODS-C18不锈钢色谱柱,甲醇/水(体积比75∶25)为流动相,在254 nm波长下对30%烯肟菌胺·噻呋酰胺悬浮剂进行定量分析。[结果]烯肟菌胺和噻呋酰胺的线性相关系数分别为0.998 7、0.999 9,标准偏差分别为0.045、0.102,变异系数分别为0.595%、0.452%,平均回收率分别为99.01%、99.25%。[结论]该方法操作简便,线性关系良好,准确率、精密度高,是烯肟菌胺·噻呋酰胺悬浮剂较为理想的分析方法。
[Objective] The research aimed to establish an HPLC method for the determination of thifluzamide suspension. [Method] The reversed-phase high performance liquid chromatography (HPLC) was used with reversed phase ODS-C18 stainless steel column and methanol / water (volume ratio 75:25) Furoamide suspension for quantitative analysis. [Results] The linear correlation coefficients of the two groups were 0.998 7 and 0.999 9, respectively. The standard deviations were 0.045 and 0.102, respectively. The coefficients of variation were 0.595% and 0.452%, respectively. The average recoveries were 99.01% and 99.25%, respectively %. [Conclusion] The method was simple and easy to operate with good linearity, high accuracy and high precision. It was an ideal analytical method for the determination of.
