Purification of total flavonoids from Rhizoma Smilacis Glabrae through cyclodextrin-assisted extraction and resin adsorption.

ABSTRACT: Flavonoids are the main bioactive components responded for the health promoting effects of Rhizoma Smilacis Glabrae (RSG), an herbal material used in many functional food of China. An eco-friendly method with β-cyclodextrin (β-CD)-assisted extraction and resin adsorption/desorption was developed for total flavonoids purification from RSG. Because of complexes formation between flavonoids and β-CD, aqueous solution was used for extraction instead of ethanol. The CD-assisted extraction was optimized through defining optimal CD species, concentration, extraction temperature, and time. The adsorption property of eight macroporous resins on astilbin was compared by adsorption kinetics and capacity. All resins could reach the adsorption equilibrium within 2 hr. Further analy
