茴拉西坦有关物质测定方法的改进

Improved HPLC Method for Determination of Related Substances in Aniracetam

摘要: 目的改进茴拉西坦的有关物质测定方法。方法采用高效液相色谱法，以C₁₈为色谱柱，流动相为乙腈-水(35∶65)，检测波长为254 nm。结果茴拉西坦与其降解产物在该色谱条件下能够有效分离。结论该方法准确可靠，可用于测定茴拉西坦的有关物质测定。

Abstract: OBJECTIVE To improve an HPLC method for determination of the related substances in aniracetam. METHODS The column was C₁₈ colum. Mobile phase was acetonitrile-water(35∶65). The detection wavelength was 254 nm. RESULTS Aniracetam and its related substances can be separated effectively by this method. CONCLUSION The method is accurate and reliable. It can be used for the related substances determination in aniracetam.
