摘　　要：采用高效液相色谱仪建立一种同时测定300 g/L五氟·吡氟酰悬浮剂有效成分含量的方法,即采用ODS-C_(18)色谱柱和紫外检测器,在210 nm波长下,以乙腈:0.1%磷酸水(体积比为70:30)为流动相,对300 g/L五氟·吡氟酰悬浮剂进行分离和定量分析。结果表明,在供试的质量浓度范围内五氟磺草胺和吡氟酰草胺质量浓度与其相应响应值之间表现出良好的线性关系,其相关系数分别为0.99996和0.9999,标准偏差为0.03和0.13,变异系数分别为0.57%和0.54%;在4个添加水平上,五氟磺草胺和吡氟酰草胺的平均回收率均为100.07%。说明该方法的线性关系好、准确度和重现性效果好,适用于300 g/L五氟·吡氟酰悬浮剂的质量控制。A method was established to determinate the active ingredients of penoxsulam·diflufenican 300 g/L suspension concentrate(SC)by HPLC-UVD with an ODS-3 C_(18) column,the mixture of 70%acetonitrile and 30%water with 0.1%phosphoric acid as the mobile phase,at detection wavelength 210 nm.The results showed that the linear correlation coefficient between mass concentrations of penoxsulam or diflufenican and their responding values were 0.99996 and 0.9999,the standard deviations were 0.03 and 0.13,the variation coefficients were 0.57%and 0.54%,respectively.And the average recovery rates was 100.07%,indicating that the method was suitable to be used for quality control of the product penoxsulam·diflufenican 300g/L SC because of its good linearity,accuracy and reproducibility.
