东乐膏HPLC指纹图谱研究

Study on HPLC Fingerprint of Donglegao

利用HPLC法对中药橡胶膏剂东乐膏进行了分离、分析 ,建立指纹图谱 .色谱条件 :HypersilODS2色谱柱 (4 .6mm× 2 5 0mm ,5 μm) ,甲醇 +1%醋酸 (体积分数 )为流动相 ,流速 1.2mL/min ,检测波长2 5 4nm .该方法简便、稳定、重现性好 。

A fingerprint of traditional Chinese rubber electuary medicine Donglegao has been studied and provides the quality information by HPLC. Hypersil ODS2 column was used, with mixtures of methanol and 1%acetic acid solution as mobile phase. The detective wavelength was 254 nm. The flow rate of mobile phase was 1.2 ml/min. The method is simple, accurate with reproducibility. It may be practical value for the quality control of Donglegao.
