Metabolite Identification
Common Name8-Hydroxy-3',4',5',7-tetramethoxyflavan
Description8-Hydroxy-3',4',5',7-tetramethoxyflavan 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. 8-Hydroxy-3',4',5',7-tetramethoxyflavan has been detected, but not quantified in, fruits. This could make 8-hydroxy-3',4',5',7-tetramethoxyflavan a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 8-Hydroxy-3',4',5',7-tetramethoxyflavan.
