The relationship between the adsorption properties for the active components of ginkgo leaves and the structure of the adsorbents based on urea-formaldehyde condensed polymers was investigated .The results revealed that these adsorbents showed very hjgh adsorption selectivity for both flavonol glycosides and terpene lactones contained in ginkgo leaves. Thus, an adsorption separation procedure for purification of ginkgo leaves extracts was developed.
