Eriocitrin also known as eriodictyol glycoside is a flavanone-7-O-glycoside between the flavanone eriodictyol and the disaccharide rutinose. It is commonly found in lemons.^[1] It is colloquially called lemon flavonoid or a citrus flavonoid, one of the plant pigments that bring color to fruit and flowers. It is a dietary supplement with lipid-lowering effects in animal models but its value in human nutrition has not been established. It is marketed as a dietary supplement usually in conjunction with B and C vitamins and other substances for relief of various ailments, but there is no established medical use or FDA approved application of the compound.
