Metabolite Identification
Common Name3',4',5',7,8-Pentamethoxyflavan
Description3',4',5',7,8-Pentamethoxyflavan belongs to the class of organic compounds known as 8-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C8 atom of the flavonoid backbone. 3',4',5',7,8-Pentamethoxyflavan has been detected, but not quantified in, fruits. This could make 3',4',5',7,8-pentamethoxyflavan a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3',4',5',7,8-Pentamethoxyflavan.
