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。
The adsorption capacity of baicalin and baicalein for 35 kinds of adsorbents with different polarities was determined. It was found that the weak base resin had a larger adsorption capacity. The adsorption kinetics of baicalin for weak base resin was studied. Resin adsorption of baicalin flavan fast, 5h has basically reached equilibrium adsorption.
