ABSTRACT
Aim:
To study new chemical constituents of the leaves of Ginkgo biloba L.Methods:
Isolation and purification were carried out by several chromatographic methods. The structures of the compounds were elucidated by detailed analysis of their UV, IR, MS, ~1H NMR and ~(13)C NMR spectraResults:
A new ginkgolide, ginkgolide N( 1, 7, 10-trihydroxy-3,14- dehydroginkgolide, Ⅱ), along with a known compound, was isolated from the leaves of G. biloba. The structure of the known one was elucidated as ginkgolide L(Ⅰ).Conclusion:
Compound Ⅱ was a new compound. The complete spectroscopic data of compound Ⅰ were reported for the first time.
