Metabolite Identification
Common NameNobiletin
DescriptionNobiletin 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, nobiletin is considered to be a flavonoid. Nobiletin is a bitter tasting compound. Nobiletin is found, on average, in the highest concentration within sweet oranges (Citrus sinensis). Nobiletin has also been detected, but not quantified in, several different foods, such as citrus, grapefruits (Citrus X paradisi), lemons (Citrus limon), mandarin orange (clementine, tangerine), and sweet bays (Laurus nobilis). This could make nobiletin a potential biomarker for the consumption of these foods. Nobiletin is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Nobiletin.
