Metabolite Identification
Common NameCitrunobin
DescriptionCitrunobin belongs to the class of organic compounds known as 2'-hydroxychalcones. These are organic compounds containing chalcone skeleton that carries a hydroxyl group at the 2'-position. Thus, citrunobin is considered to be a flavonoid. Citrunobin has been detected, but not quantified in, citrus and sweet oranges (Citrus sinensis). This could make citrunobin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Citrunobin.
