Abstract: In this study,the adsorption properties of AB-8 resin for anthocyanins from Lonicera edulis Turcz were investigated.The adsorption isotherm,thermodynamic properties and dynamic parameters of AB-8 resin were analyzed.The results indicated that under experimental conditions of static adsorption,the adsorption of AB-8 resin for anthocyanins from L.edulis was an exothermic process,and the adsorption capacity was strong,the adsorption parameters fit Freundlich equation well with correlation coefficient greater than 0.98.The results of dynamic adsorption showed that the optimal feed concentration was 280±20 mg/mL,elution speed was 2.5 mL/min.The eluting liquid of anthocyanin varieties were analyzed and identified using LC-MS.The results of this study provided a theoretical foundation for the purification anthocyanins from L.edulis using simulated moving bed chromatography.
