摘要
采用Waters Symmetry C18反相色谱柱,以乙腈+甲醇+水为流动相,在256 nm紫外波长下对克瘟散原药进行反相高效液相色谱法测定,原药有效成分的相对保留时间约为13.6 min。以外标法定量测得本方法的变异系数为0.19%,平均回收率为100.08%,线性相关系数为0.999 7。
The content of edifenphos was determined by reversed phase HPLC with the column of Waters Symmetry C18 and the mobile phase of methanol / water / acetonitrile at 256 nm.The variation coefficient,the average recovery rate and the coefficient of linear correlation were 0.19%,100.08% and 0.999 7,respectively.
