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.
Ginkgo biloba | Natura Foundation
In Nederland is de Ginkgo biloba bekend als ginkgoboom of tempelboom. De naam “tempelboom” verwijst naar het voorkomen van deze boom rond de tempels in oude tijden. De Chinezen zagen de tempelboom als een heilige boom, vereerden en beschermden de boom. Dat de boom miljoenen jaren heeft kunnen overleven, is mede te danken aan de goede ...

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 radicaalvorming.
