摘  要:
建立一种测定30%吡唑醚菌酯·乙嘧酚悬浮剂中有效成分含量的高效液相色谱法,用ZORBAX SB-C18反相柱和紫外可变波长检测器,以乙腈-水(85+15,体积比)为流动相,分析吡唑嘧菌酯·乙嘧酚复配制剂,以外标法进行分析和定量。结果表明,吡唑醚菌酯和乙嘧酚标准偏差分别为0.06和0.08,变异系数分别为0.58%和0.42%,平均回收率分别为100.03%和100.10%。该方法准确度、精密度较高,适用于吡唑醚菌酯·乙嘧酚悬浮剂的分析检测。

摘  要:
A method for simultaneous analysis of pyraclostrobin and ethririmol of pyraclostrobin·ethirimol 30% SC by HPLC was established. Chromatographic experiments were performed on ZORBAX SB-C18 column, with UV-absobance detector, and mobile phase using acetonitrile + water. The effective components were also determined and quantified by external standard method. The results showed that the standard deviations of pyraclostrobin and ethirimol were 0.06 and 0.08, the variation coefficients were 0.58% and 0.42%, the average recoveries were 100.03% and 100.10%, respectively. The method was simple, rapid, accurate, and suitable for the qualitative and quantitative analysis of pyraclostrobin·ethirimol SC.
