Abstract

Abstract: In search of a polymeric adsorbent suitable for the separation or purification of flavones and other phenolic natural products, the adsorption capacities of thirty-five polar polymeric adsorbents for baicalin and baicalein were measured respectively.The results show that some basic adsorbents possess larger capacities.The adsorption kinetics of aminomethylated cross-linked polystyrene was then determined.Its adsorption for baicalein would reach to an equilibrium in about five hours.

Key words: Polymeric adsorbent, Basic resin, Baicalin, Baicalein
