Bioflavonoids comprise a diverse class of compounds with antioxidant activity. They are found naturally in the leaves, bark, roots, flowers, and seeds of plants.
Hesperidin is a flavonoid found in the pith of unripe citrus fruits. Chemically, it is a complex of glucose and rhamnose with the flavonone hesperin. At one time it was called vitamin P, since it affects the fragility of capillary walls. (However, it is not technically a vitamin.)
Rutin belongs to a class of water-soluble plant pigments called flavonoids. It is the disaccharide derivative of quercetin, containing glucose and rhamnose. Rutin can be found in grains, tomato stalks, and elderberry blossoms. A variety of evidence indicates that rutin possesses strong antioxidant properties.
Quercetin belongs to a class of water-soluble plant pigments called flavonoids. A variety of evidence indicates that quercetin also possesses strong antioxidant properties.
The antioxidant activities of bioflavonoids complement, extend, and sometimes synergize the antioxidant activities of vitamin C, vitamin E, and carotenoids. As such, bioflavonoids represent an important nutritional component in the body’s defenses against free radical damage.
