Common Name | Fraxin |

Description | Fraxin belongs to the class of organic compounds known as coumarin glycosides. These are aromatic compounds containing a carbohydrate moiety glycosidically bound to a coumarin moiety. Fraxin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Fraxin is found in Actinidia chinensis, Aesculus turbinata, Apis cerana, Tetradium glabrifolium, Fraxinus angustifolia, Fraxinus chinensis, Fraxinus floribunda, Fraxinus mandshurica, Fraxinus micrantha, Fraxinus pallisae, Lupinus angustifolius, Prunus prostrata, Rhododendron groenlandicum, Sarcandra glabra and Weigela subsessilis. Fraxin was first documented in 1992 (PMID: 1298368). Based on a literature review a small amount of articles have been published on fraxin (PMID: 26945887) (PMID: 28383514) (PMID: 28922728) (PMID: 30348388). |
