摘要
目的：建立同时测定萘普生的含量及有关物质的高效液相色谱法。方法：色谱柱采用C18柱（ZORBAX C18 14．6mm×150mm，5μm），流动相为乙腈-水-冰醋酸（50：49：1），检测波长为254nm。结果：本法的平均回收率为94．9％，相对标准偏差为0．15％，在5—45μg／ml的浓度范围之间呈线性。结论：本法可同时测定萘普生含量及其有关物质含量，且简便、灵敏、准确。
Objective： To develop a HPLC method for determination of content of naproxen and its related substances in naproxen colored tablets. Method： The separation was performed on a ZORBAX C18 Cohunn （4.6 mm ×150mm,5μm） with acet onitrile-water-glacial acetic acid （50： 49： 1 ） as mobile phase. The detection wavelength was set at 254 nm . Result： The average recovery of naproxen using this method was 94.9%. RSD was 0.15% .Results of this method showed linear correlation in the range of 5 - 45μg/ml. Conclusion： The HPLC method developed is simple, sensitive and accurate. It can be used for determination of content of naproxen and its related substances in naproxen colored tablets.
