Metabolite Identification
Common NameLimocitrol
DescriptionLimocitrol belongs to the class of organic compounds known as flavonols. Flavonols are compounds that contain a flavone (2-phenyl-1-benzopyran-4-one) backbone carrying a hydroxyl group at the 3-position. Thus, limocitrol is considered to be a flavonoid. Limocitrol has been detected, but not quantified in, citrus and lemons (Citrus limon). This could make limocitrol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Limocitrol.
