Metabolite Identification
Common Name3'-Hydroxy-4',5,6,7,8-pentamethoxyflavone
Description3'-Hydroxy-4',5,6,7,8-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, 3'-hydroxy-4',5,6,7,8-pentamethoxyflavone is considered to be a flavonoid. 3'-Hydroxy-4',5,6,7,8-pentamethoxyflavone has been detected, but not quantified in, citrus and mandarin orange (clementine, tangerine). This could make 3'-hydroxy-4',5,6,7,8-pentamethoxyflavone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 3'-Hydroxy-4',5,6,7,8-pentamethoxyflavone.
