若干极性树脂对黄芩甙及黄芩黄素的吸附性能研究

Investigation on the Adsorption Properties of Thirty-five Polar Polymeric Adsorbents for Baicalin and Baicalein

测定了35种具有不同极性的吸附树脂对黄芩甙及黄芩黄素的吸附量,发现弱碱树脂具有较大的吸附量,研究了弱碱树脂对黄芩黄素的吸附动力学,观察到该树脂对黄芩黄素的吸附较快,5h已基本达到吸附平衡。

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.
