Chemical Information
FooDB NameLimocitrin
DescriptionLimocitrin 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, limocitrin is considered to be a flavonoid. Limocitrin has been detected, but not quantified in, citrus and lemons (Citrus limon). This could make limocitrin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Limocitrin.
