| 摘 要： | I INTRODUCTIONGinkgo biloba L. is one of the important economic trees, which is widely distributed inChina. In recent years, medicinal and healthful preparations based on the extractS from ginkgoleaves have been rapidly developed for the treatment of peripheral circulatory and cerebralinsufficiencyl']. Such eXtracts contain flavonol glycosides and terpene lactones as thepharmacologically active compounds. Organic-solvent extraction is one of the earliest methodsto prepare the extracts o…

| Abstract: | 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. |
