| Common Name | Ginkgolide B |
|---|
| Description | Ginkgolide-B 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. The cis-fused F/A/D/C ring junction forms an empty semi-ball hole, the D ring contains a cage form tetrahydrofuran ring which occupies the center of the empty hole, and the oxygen atoms of the D,C and F ring and 10-hydroxyl group consist of an analogous crown ether structure. Ginkgolide B is found in Machilus wangchiana. Ginkgolide-B is an extremely weak basic (essentially neutral) compound (based on its pKa). |
