Metabolite Identification
Common Name5-Hydroxy-3,3',4',7,8-pentamethoxyflavone
Description5-Hydroxy-3,3',4',7,8-pentamethoxyflavone 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, 5-hydroxy-3,3',4',7,8-pentamethoxyflavone is considered to be a flavonoid. 5-Hydroxy-3,3',4',7,8-pentamethoxyflavone has been detected, but not quantified in, sweet oranges (Citrus sinensis). This could make 5-hydroxy-3,3',4',7,8-pentamethoxyflavone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5-Hydroxy-3,3',4',7,8-pentamethoxyflavone.
