Metabolite Identification
Common NameIsoginkgetin
DescriptionIsoginkgetin belongs to the class of organic compounds known as biflavonoids and polyflavonoids. These are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3'-C3''', and C6-C8''. Thus, isoginkgetin is considered to be a flavonoid. Isoginkgetin has been detected, but not quantified in, fats and oils and ginkgo nuts (Ginkgo biloba). This could make isoginkgetin a potential biomarker for the consumption of these foods. Isoginkgetin 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 Isoginkgetin.
