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]
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 …
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
Ginkgolides are diterpenoid trilactone-containing unique C 20 lactone cage molecules that are the main principles from the slow-growing Ginkgo biloba L. (especially from leaf part), which are from gymnospermous tree, species in the division ginkgophyta, and a single surviving species belonging to the family of ginkgoaceae in a class ...

Ginkgolide B: Origin, Pharmacokinetics and ... - ChemicalBook
In a more recent study involving 24 volunteers, the pharmacokinetics of commercially available Ginkgolide B preparations were investigated. The study assessed plasma concentrations of Ginkgolides A, Ginkgolide B, and bilobalide following oral administration of the preparations.

Nine different structures of ginkgolides have been presented in ginkgo (Ma et al., Citation 2016). Ginkgo biloba has antiproliferative and anticancer activities in several in vitro studies (Ahmed et al., Citation 2017; Silva et al., Citation 2019), and these effects may be related to the presence of flavonoids (Slika et al., Citation 2022).
The Potential of Ginkgo biloba as a Source of Biologically Active ...
The terpene trilactones present in ginkgo, including ginkgolides A, B, C and bilobalide, correspond, inter alia, to its anti-epileptic effect on neurons within the brain’s hippocampus, improving memory and learning ability and ameliorating neuronal damage.
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.
Ginkgo biloba, werkingsmechanismen en klinische toepassingen - Orthokennis
PAF-antagonisme, ontstekingsremmende activiteit Ginkgo-extract (met name ginkgolides) is een antagonist van PAF (platelet activating factor). PAF bevordert bloedplaatjesaggregatie, is een krachtige ontstekingsmediator en bevordert ontstekingen, allergische reacties, ischemie/reperfusieschade, pijn, oedeem, trombose en vrije ...
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.
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).
Ginkgolide – Wikipedia
Nakanishi konnte zeigen, dass der Ginkgo-Baum radioaktives 14 C aus den markierten Verbindungen Natriumacetat, Mevalonsäure und Methionin in Ginkgolide einbaut. [1] Damit war der Beweis des terpenoiden Ursprungs der polycyclischen Hydroxylactone aus Ginkgo biloba erbracht. Die genaue Biosynthese ist bislang nicht in allen Einzelheiten geklärt.
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).
The Chemistry and Biology of Ginkgolide B - ChemicalBook
Ginkgolides are complex polyoxygenated diterpenoids isolated from the leaves and root bark of the Ginkgo biloba tree, also known as the maidenhair tree or as the “living fossil”, as its fossils date back to the Jurassic period (170 M years).
Ginkgolide — Wikipédia
Les ginkgolides ont été isolés pour la première fois en 1932 à partir de Ginkgo biloba [1]. Leur structure a commencé à être élucidée en 1967 avec le ginkgolide B [2]. On en connaissait, fin 2014, cinq molécules différentes, appelées ginkgolides A, B, C, J et M :
