Metabolite Identification

Common Name

5,7-Dihydroxy-3-methoxyflavone

Description

5,7-Dihydroxy-3-methoxyflavone, also known as galangin 3-methyl ether or 3-methylgalangin, belongs to the class of organic compounds known as 3-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C3 atom of the flavonoid backbone. Thus, 5,7-dihydroxy-3-methoxyflavone is considered to be a flavonoid. 5,7-Dihydroxy-3-methoxyflavone is found, on average, in the highest concentration within mexican oreganos (Lippia graveolens). 5,7-Dihydroxy-3-methoxyflavone has also been detected, but not quantified in, herbs and spices. This could make 5,7-dihydroxy-3-methoxyflavone a potential biomarker for the consumption of these foods. 5,7-Dihydroxy-3-methoxyflavone 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 very few articles have been published on 5,7-Dihydroxy-3-methoxyflavone.
