Metabolite Identification
Common NameDemethylnobiletin
DescriptionDemethylnobiletin 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, demethylnobiletin is considered to be a flavonoid. Demethylnobiletin has been detected, but not quantified in, several different foods, such as winter savories (Satureja montana), citrus, herbs and spices, peppermints (Mentha X piperita), and spearmints (Mentha spicata). This could make demethylnobiletin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Demethylnobiletin.
