In order to separate and purify flavones from peanut hull,the static adsorption behaviors of eight kinds of macroporous resin for peanut hull flavonoids(PHF) were studied and the optimum macroporous resin was screened in the present work.Additionally,the adsorption performance of the proper macroporous resin for PHF was researched and the optimum parameters of the adsorption were procured.Results: AB-8 macroporous resin is selected as the optimum macroporous resin to extract and separate PHF under the experimental condition,and the adsorption equilibrium time of AB-8 for PHF is 4 h.The optimum technological parameters of the adsorption and separation are pH 6.0,velocity of flow 1 mL/min and sample solution concentration 0.5 mg/mL.When 70% ethanol is used as eluant,the desorption capacity is 94.23%,and eluant 3 BV can desorb PHF basically.
