| Abstract: | The leaves of Ginkgo biloba were extracted with 70% ethannol under reflux. For avoiding the loss of flavonoid the extract was concentracted under vacuum, to a proportion of 7:1. The extraction yield and the content of flavonoid had a marked increase. Ginkgolide B was isolated by TLC and colum chromatography. |
