ABSTRACT
Objective To study the adsorption and separation of licorice flavonoid with macroporous resins. Methods Eight types of macroporous resin were selected to compare their performances in absorbing and desorbing licorice flavonoid. The optimal type for licorice flavonoid was decided, meanwhile, its kinetic curve and dynamic absorbing behavior were studied. Results HPD300 resin possessed higher adsorption and desorption capacity. The appropriate adsorption and desorption conditions were as followsconcentration of sample was 2.0 mg/mL, velocity of sample solution was 1.5 BV/h, volume of sample solution was 2 BV (bed volume);velocity of 80%ethanol was taken as eluant 1.5 BV/h, and the volume was 3 BV. Flavonoid content was increased more than 2 times under above conditions. Conclusion HPD300 macroporous resin showed better comprehensive adsorption property. It can be used to purify and separate licorice flavonoid.
