28%嘧菌·丙环唑悬乳剂高效液相色谱分析

Analysis of Azoxystrobin+Propiconazol 28% SE by HPLC

建立了高效液相色谱法分析丙环唑与嘧菌酯复配制剂,使用ZORBAX Eclipse Plus C8反相柱和紫外可变波长检测器,以甲醇+水为流动相,采用外标法对有效成分进行分析和定量。丙环唑和嘧菌酯相关系数分别为0.999 4和0.999 3,标准偏差分别为0.09和0.10,变异系数分别为0.50%和0.93%,平均回收率分别为99.20%和99.56%。

A method was developed for the determination of azoxystrobin ＋ propiconazol 28% SE by HPLC on ZORBAX Eclipse Plus C8 column, using methanol ＋ water as mobile phase. The results showed that the linear correlation coefficients of propiconazol and azoxystrobin were 0.999 4 and 0.999 3, the standard deviations were 0.09 and 0.10, the variation coefficients were 0.50% and 0.93%, and the average recoveries were 99.20% and 99.56%, respectively.
