特非那定片溶出度检查和含量测定流动相的改进
Improvement on mobile phase of dissolution and determination of terfenadine tablets
-
摘要: 目的: 对特非那定片标准中溶出度检查与含量测定的流动相进行选择,统一为一个流动相。 方法: 采用高效液相色谱法。 结果: 流动相Ⅲ为乙腈-磷酸盐缓冲液(50:50),其出峰时间最短,峰形良好且专属灵敏。 结论: 建议将两个检测项目中的流动相统一为流动相Ⅲ。Abstract: Objective: To find a ideal and unified mobile phase both of dissolution test and content determination of terfenadine tablets. Methods: HPLC was used. Results: The mobile phaseⅢ[a mobile phase composed of acetonitrile-phosphate buffer(50:50)] was applied,t_R is shorter,the peak shape is better and the methods are specific and sensitive. Conclusion: The mobile phaseⅢis recommended as a ideal and unified mobile phase of dissolution and determination for terfenadine tablets.
