Studies on Separation and Purification of Total Flavones from Folium Ginkgo Leaves by Macroporous Adsorption Resin

Ying Chen

Abstract

The total flavones from Folium ginkgo leaves were seperated and purified by four kinds of macroporous adsorption resin.The results showed that resin HPD100 was the most efficient one with static adsorption capacity of 63.8 mg·g-1,static elution rate of 91.2% and dynamic saturated adsorption capacity of 14.0 mg·g-1 with 4 BV 70% ethanol as eluting reagent.Furthurmore,resin HPD100 could be repeatly used for 7 cycles.
