Abstract

In this paper,five macroporous adsorption resins were chosen to compare their adsorption and desorption performances for flavonoids from Walnut Shell by using static adsorption experiment.The best performance resin was NKA-9.Its dynamic adsorption performance was further studied.The excellent technological parameters were: sample pH value 5.0,velocity 1.0 mL/min,concentration 1.0 mg/mL and 5BV 95% ethanol.The purity of flavonids was 3.58% in the crude extracts from walnut shell,and increased to 62.3% after purification with NKA-9 resin.The coefficient of recovery was 88.9%.

Key words： walnut shell; flavonoids; macroporous adsorption resin; separation; adsorption
