Metabolite Identification
Common NameIsosinensetin
DescriptionIsosinensetin 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, isosinensetin is considered to be a flavonoid. Isosinensetin has been detected, but not quantified in, several different foods, such as citrus, fruits, mandarin orange (clementine, tangerine), and sweet oranges (Citrus sinensis). This could make isosinensetin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Isosinensetin.
