Metabolite Identification
Common Name5-Hydroxy-7-methoxy-6-methylflavone
Description5-Hydroxy-7-methoxy-6-methylflavone belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, 5-hydroxy-7-methoxy-6-methylflavone is considered to be a flavonoid. 5-Hydroxy-7-methoxy-6-methylflavone has been detected, but not quantified in, several different foods, such as black tea, green tea, herbal tea, red tea, and teas (Camellia sinensis). This could make 5-hydroxy-7-methoxy-6-methylflavone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 5-Hydroxy-7-methoxy-6-methylflavone.
