Common NameHirsutidin
DescriptionHirsutidin belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, hirsutidin is considered to be a flavonoid. Hirsutidin 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. Hirsutidin is found in Catharanthus roseus, Catharanthus roseus G.Don. and Primula hirsuta. Hirsutidin was first documented in 2003 (PMID: 12628396). Based on a literature review very few articles have been published on hirsutidin (PMID: 34146990).
