【摘要】 采用大孔吸附树脂分离纯化紫锥菊提取物中免疫活性成分菊苣酸 ,7% (v/v)的甲醇 水溶液洗脱 ,HPLC法对产品中菊苣酸含量进行检测分析。该法能把紫锥菊提取物中菊苣酸含量 (4 % )提高 9倍左右 ,回收率达到 95 %以上 ,且操作简单 ,可用于菊苣酸的分离纯化。更多还原

【Abstract】 Developed a method to separate and enrich the immunocompetence constituent cichoric acid from the extracts of Echinacea purpurea with macroporous adsorption resin,by eluting with 7% (v/v) CH 3OH-H 2O. Cichoric acid content in product quantified by HPLC was nine times higher than that (4%) of the extracts of Echinacea purpurea. The recovery of cichoric acid was more than 95%. The technology was simple and could be applied to separate and purify cichoric acid.更多还原
