Eriocitrin

Eriocitrin (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. This antioxidant also predominates (38% in 1 study) in Peppermint infusions.
