Ginkgolide - an overview | ScienceDirect Topics
The ginkgolides are a unique class of diterpenoids isolated from the ‘fossil’ tree Ginkgo biloba L. This tree is the only remaining species of the Ginkgoales, once a very large order, and its extreme botanical position is matched by the unusual chemistry of its constituents.
Therapeutic promises of ginkgolide A: A literature-based review
Ginkgolide A is a highly active platelet activating factor antagonist cage molecule which was isolated from the leaves of the Ginkgo biloba L. It is known for its inflammatory and immunological potentials. This review aims to sketch a current scenario on its therapeutic activities on the basis of sc …
