The separation and purification of ginkgo biloba flavone by a functional polymer(the oxide of polymer of rosin allyl alcohol ester) was explored.For functional polymer of rosin allyl alcohol ester,the static adsorption of ginkgo biloba flavone was 22.6 mg·g-1and the dynamic adsorption of ginkgo biloba flavone was 4.7 mg·g-1.For functional polymer of cross-linking polymerized rosin allyl alcohol ester,the static adsorption of ginkgo biloba flavone was 14.2 mg·g-1 and the dynamic adsorption was 5.5 mg·g-1.The...
