ABSTRACT
Objective To study the feasibility of using chelating resins D751 and D403 to remove the heavy metals from the extracts of Folium Ginkgo (FG). Methods Heavy metal removal experiments were performed on automatic control platform in industry mode. With dry ointment yield,total content of flavones,comparability of HPLC and removal rate of heavy metal as the indexes,the effects of two kinds of chelating resins on removing heavy metal were compared. Result After removing heavy metal by resins D751 and D403,the loss rate of the dry extract were less than 6%,and the heavy metal contents were lower than national limits;HPLC similaritites were higher than 0.98,and the loss rates of total flavones were less than 5%. Conclusion Chelating resins D751 and D403 can be used to remove heavy metal from extracts of Folium Ginkgo.
