DM-130 macro-porous adsorptive resin was used to extract flavonoid glycosides from leaching solution and some factors affecting the adsorption efficiency were examined. The optimum technological conditions as follows:pH=5, mass ratio of liquid to solid 15 in adsorption and 70% ethanol as eluting agent. Resin could be regenerated after every three time uses. The content of flavonoids glycosides in extracts was about 24%.
- gingko leaves,
- flavonoids glycoside,
- extract,
- macro porous adsorptive resin
