Selective Adsorption of Flavonoids on Chitosan Resin Grafted by Quercetin

Chitosan resin grafted by quercetin (QCR), the adsorbent, was used as for the separation of flavonoids. The optimum conditions were determined by automatic liquid chromatography system. Moreover, the hydrophobic interaction between the flavonoids and QCR could be useful for the effective adsorption and separation.
