Gentisin

Description

Gentisin, also known as gentianin or gentianic acid, belongs to the class of organic compounds known as xanthones. These are polycyclic aromatic compounds containing a xanthene moiety conjugated to a ketone group at carbon 9. Xanthene is a tricyclic compound made up of two benzene rings linearly fused to each other through a pyran ring. Gentisin 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. Based on a literature review a significant number of articles have been published on Gentisin.
