摘要
建立起13%井冈.水杨酸钠水剂中水杨酸钠含量测定的高效液相色谱方法。选用ODS-C18填料的色谱柱(250 mm×4.6 mm,5μm)和二极管阵列检测器;流动相:乙腈∶水(50∶50);流速1.0 mL/min;检测波长:299 nm,水杨酸钠标准偏差为0.044,变异系数为0.4%,线性相关系数为0.9998,平均回收率为99.5%。
A method for the quantitative analysis of sodium salicylate in 13 % validamycin, sodium salicylate AS by reversed-phase HPLC was studied. Using aeetonitrile and water as mobile phase, ODS-C18 column and DAD at 299 nm. The results showed that standard deviation was 0.044, the variation conefficient was 0.4 %, the linear correlation was 0.9998 and the average recovery rate was 99.5 %.
