摘  要：
[目的]建立16%精喹.氟磺胺草醚乳油的反相高效液相色谱分析方法。[方法]采用反相高效液相色谱法,使用C18柱和二极管阵列检测器,以乙腈和0.5%磷酸水溶液(体积比80∶20)为流动相,流速为1.0 mL/min,在254 nm波长下,对精喹禾灵和氟磺胺草醚同时进行定量分析。[结果]氟磺胺草醚的变异系数为1.47%,平均回收率为99.87%,线性相关系数为0.9999;精喹禾灵的变异系数为0.71%,平均回收率为100.26%,线性相关系数为0.999 9。[结论]该方法准确度和精密度均能满足要求,线性关系良好,具有分离效果好、简便、快速、准确的优点,是一种较为理想的分析方法。

摘  要：
A quantitative analysis method was established for fomesafen and quizalofop-p-ethyl 16% EC by the reversed phase HPLC.[Methods] The fomesafen and quizalofop-p-ethyl was quantitatively analyzed simultaneously by HPLC with C18 column at UV 254 nm,and the mixture of acetonitrile and phosphoric acid solution(20∶80,by vol) was used as the mobile phase with flow rate of 1.0 mL/min.[Results] The results showed that cofficient of variation of fomesafen was 1.47%,recovery ration was 99.87%,linear correlation coefficients was 0.9999,cofficient of variation of quizalofop-p-ethyl was 0.71%,recovery ration was 100.26%,linear correlation coefficients was 0.9999.[Conclusions] The method with high precision and accuracy was suit for quantitative analysis,and was also an ideal analysis method with the advantages of good separation,convenience,fast speed,and high precision and accuracy.
