Abstract:

Totally, 12 macroporous resins were tested for their adsorption and desorption performance to total flavonoids from Chrysanthemum indicum L., and 3 of them, namely XDA-1, LSA-21 and AB-8 resins were selected for subsequent studies, which were carried out to investigate the static adsorption and desorption behaviors of the selected resins. Finally, XDA-1 resin was selected to purify crude total flavonoid extract from Chrysanthemum indicum L. due to its higher adsorption capacity (84.1mg/g) and desorption ratio (96.2%) and better static adsorption kinetics than those of LSA-21 and AB-8 resins. The optimum pH for XDA-1 resin adsorption ranged from 4 to 5 and the optimum desorption solvent 70% ethanol.

Key words: Chrysanthemum indicum L., total flavonoids, macroporous resin, adsorption, separation
