| Common Name | Limocitrin |
|---|
| Description | Limocitrin, also known as sedoflorigenin, 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 lipid molecule. Limocitrin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Limocitrin has been detected, but not quantified in, citrus and lemons. Limocitrin is found in Citrus unshiu, Coronilla valentina, Dryas octopetala , Erica cinerea, Haplophyllum acutifolium, Lotus corniculatus , Sedum acre and Sedum laconicum. This could make limocitrin a potential biomarker for the consumption of these foods. |
