Rutin: Quercetin-3-O-Rutinoside Bioflavonoid from Sophora and Buckwheat
Rutin (quercetin-3-O-rutinoside) is a glycoside flavonoid composed of quercetin and the disaccharide rutinose. It is found in high concentrations in buckwheat, Sophora japonica flower buds, citrus fruits, and asparagus. Rutin is recognized for its vasoprotective properties, particularly its ability to reduce capillary permeability and fragility, and serves as the primary industrial source material for quercetin production through enzymatic or acid hydrolysis.

Applications
Rutin has a long history of use in pharmaceutical products for venous insufficiency, hemorrhoids, and capillary fragility. In Europe, rutin derivatives such as troxerutin and hydroxyethylrutosides are used in phlebotropic drug formulations. Nutraceutical supplements combine rutin with vitamin C for cardiovascular and immune health support. In the food industry, rutin acts as a natural antioxidant. It is also an important chemical intermediate — enzymatic or acid hydrolysis of rutin is the primary commercial route to produce quercetin aglycone.
