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。

STUDY ON ADSORPTION AND PURIFICATION OF CICHORIC ACID IN EXTRACTS OF ECHINACEA PURPUREA WITH MACROPOROUS ADSORPTION RESIN |
| |
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. |

Keywords: | macroporous adsorption resin extracts of Echinacea purpurea cichoric acid |
