Ginkgolide - Wikipedia
Ginkgolides are biologically active terpenic lactones present in Ginkgo biloba. They are diterpenoids with 20-carbon skeletons, which are biosynthesized from geranylgeranyl pyrophosphate. [1]

Ginkgolides have several different biological effects including inhibiting platelet aggregation, preventing apoptosis and oxidation, providing nutrition to nerves, and regulating neuroimmunity.
Ginkgolide - an overview | ScienceDirect Topics
Ginkgolides are pharmacologically-active diterpenes found in Ginkgo biloba (Ginkgoaceae), which have been widely reported to have several pharmacological properties, including anti-inflammatory effects; for example, Ginkgolides A–C, J and M (Fig. 4).
Ginkgolides and Their Derivatives: Synthetic and Bioorganic Studies
The isolation of ginkgolides from Ginkgo biloba extracts represents the main source of these trilactones for all synthetic, structural, and biological studies. However, some ginkgolides are more abundant in the extracts than others.
Biosynthesis pathways of ginkgolides - PMC
This review focuses on the biosynthetic pathways of ginkgolides, the enzymes related to the biosynthesis of the ginkgolides, the genes encoding the enzymes cloned from the ginkgo, and the factors influencing the production of ginkgolides in cell cultures.
Ginkgolide A: Uses, Interactions, Mechanism of Action - DrugBank Online
This compound belongs to the class of organic compounds known as ginkgolides and bilobalides. These are diterpene lactones with a structure based either on the gingkolide or the bilobalide skeleton. The ginkgolide skeleton is a very rigid structure consisting of hexacyclic C20 trilactone.
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.
Role of Ginkgolides in the Inflammatory Immune Response of Neurological ...
Ginkgolides are natural PAFR antagonists that selectively and competitively antagonize PAF-induced platelet aggregation (Gui et al., 2007). It is well established that PAF signaling plays a pivotal role in the initiation and progression of inflammatory and thrombotic reactions, as well as in the cross talk between them (Stafforini et al., 2003).
Ginkgolides and bilobalide: Their physical, chromatographic and ...
Ginkgolides A, B, C, J, K, L and M and bilobalide are rare terpene trilactones that have been isolated from leaves and root bark of the Chinese tree Ginkgo biloba. The structures of the highly oxidized ginkgolides were independently elucidated in the 1960s by the groups of Nakanishi and Sakabe.
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 …
