Abstract
Four compounds were isolated from ethyl acetate extract of the leaves of Ginkgo biloba. Compounds II, III, IV were identified as ginkgolides A, B and C respectively, Compound I, which was obtained from the leaves of G. biloba for the first time, was identified as 3,3'-dimethoxy-4,4'-dihydroxy-stilbene by spectroscopic methods.
