Separation and purification technology of ferulic acid in Angelica sinensis by macroporous adsorption resin / 中草药

Objective To select the suitable macroporous adsorption resins for enrichment and purifi-cation ferulic acid from Angelica sinensis so as to improve the product quality. Methods Macroporous ad-sorption resins were used to study the adsorption and desorption characteristics of ferulic acid. At the same time HPLC was used in detection. Results The best resin DA201 was chosen and the optimum parameters were obtained. The content of ferulic acid was increased from 0. 15% in the raw material to 25.1%. Con-clusion The material has a low cost and the operation is easy. The adsorption resins can be used again,which has a good applied foreground.
