Metabolite Identification
Common Name3,3',4',5,7,8-Hexamethoxyflavone
Description3,3',4',5,7,8-Hexamethoxyflavone 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. Thus, 3,3',4',5,7,8-hexamethoxyflavone is considered to be a flavonoid. 3,3',4',5,7,8-Hexamethoxyflavone has been detected, but not quantified in, citrus and sweet oranges (Citrus sinensis). This could make 3,3',4',5,7,8-hexamethoxyflavone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3,3',4',5,7,8-Hexamethoxyflavone.
