Metabolite Identification
Common NameCitracridone I
DescriptionCitracridone I, also known as citra-i, belongs to the class of organic compounds known as acridones. These are acridines containing a ketone group attached to the C9 carbon atom of the acridine moiety. Citracridone I is found, on average, in the highest concentration within sweet oranges (Citrus sinensis). Citracridone I has also been detected, but not quantified in, citrus. This could make citracridone I a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Citracridone I.
