Metabolite Identification
Common NameTangeritin
DescriptionTangeritin 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, tangeritin is considered to be a flavonoid. Tangeritin is a bitter tasting compound. Tangeritin is found, on average, in the highest concentration within sweet oranges (Citrus sinensis). Tangeritin has also been detected, but not quantified in, several different foods, such as mandarin orange (clementine, tangerine), broccolis (Brassica oleracea var. italica), green tea, sweet bays (Laurus nobilis), and black tea. This could make tangeritin a potential biomarker for the consumption of these foods. Tangeritin 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 Tangeritin.
