A novel solid phase for selective separation of flavonoid compounds

A novel straightforward approach to selective separation for flavonoid compounds was reported. The solid phase material was prepared by copolymerization using allyl‐bromide‐modified chitosan as macromonomer, and ethylene glycol dimethacrylate as cross‐linker.

Description
Summary:A novel straightforward approach to selective separation for flavonoid compounds was reported. The solid phase material was prepared by copolymerization using allyl‐bromide‐modified chitosan as macromonomer, and ethylene glycol dimethacrylate as cross‐linker. The material was evaluated by chromatographic analysis; it exhibited high selectivity separation for quercetin and its structural analogues using different mobile phases. The material could directly trap a specific class of compounds including quercetin and kaempferol from the hydrolyzate of Ginkgo biloba extract. These results demonstrated the possibility of direct extraction of certain constituents from herb using this material.
