摘要
目的建立地龙注射液中游离氨基酸的HPLC指纹图谱。方法采用2,4-二硝基氟苯柱前衍生化法,用HPLC法进行梯度洗脱分析地龙注射液中游离的氨基酸。结果通过优化衍生条件,得到分离度、重复性均较好的HPLC指纹图谱,确定了14个共有峰,以缬氨酸为参照峰,用中药指纹图谱相似度软件计算不同批次样品的相似度均在0.97以上。结论本研究建立的指纹图谱,可用于地龙注射液的质量控制。
Objective To establish the HPLC fingerprints of free amino acids in Dilong injection. Methods 1-fluoro-2,4-dinitrobenzene was used for the pre-column derivation of amino acids in the Dilong injection, then analyzed with acetonitrile-DMF-sodium acetate gradient elution. Results The HPLC fingerprints were well separated. Fourteen common peaks were obtained. The similarities among different batches of samples were all above 0.97 when using valine as reference peak. Conclusion This method could be used for the quality control of Dilong injection.
