摘要
使用XDB-C_(18)色谱柱和PDA检测器,以乙腈-乙酸铵水溶液为流动相,建立了测定硝磺草酮原药中硝基呫吨酮杂质的HPLC方法。结果表明,硝基呫吨酮的线性相关系数为0.9996,相对标准偏差为6.11%,平均回收率为108.20%。该方法具有较高的准确度和精密度,适用于硝磺草酮原药中硝基呫吨酮杂质的检测。
The HPLC method for determination of nitroxanthone in mesotrione was established with XDB-C_(18) column and PDA detector,using acetonitrile-ammonium acetate aqueous solution as mobile phase.The results showed that the linear correlation coefficient of nitroxanthone was 0.9996.The relative standard deviation was 6.11%,and the average recovery was 108.20%.The method was suitable for the analysis of nitroxanthone in mesotrione with high precision and accuracy.
