Metabolite Identification
Common Name3,5,6-Trihydroxy-3',4',7-trimethoxyflavone
Description3,5,6-Trihydroxy-3',4',7-trimethoxyflavone belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, 3,5,6-trihydroxy-3',4',7-trimethoxyflavone is considered to be a flavonoid. 3,5,6-Trihydroxy-3',4',7-trimethoxyflavone has been detected, but not quantified in, citrus. This could make 3,5,6-trihydroxy-3',4',7-trimethoxyflavone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3,5,6-Trihydroxy-3',4',7-trimethoxyflavone.
