Abstract

Abstract: A method for preparing porous alumina beads using a cation exchange resin with sulfonic acid groups as templates was reported. And the beads were characterized by using XRD, SEM and BET method . The adsorption selectivity of the beads towards flavonol glycosides and terpene lactones was discussed, and adsorption mechanism was investigated by FTIR. The beads were used to separate terpene lactones from the extract of Ginkgo biloba leaves. And the purity of terpene lactones in the product was 58.5%, furthermore, there were no flavonol glycosides in it.

Key words: Flavonol glycoside, Terpene lactone, Alumina, Ion-exchange resin
