Rutin, also called rutoside, is the glycoside combining the flavonol quercetin and the disaccharide rutinose.
Rutin is a glycoside of the flavonoid quercetin. As such, the chemical structures of both are very similar，with the difference existing in the hydroxyl functional group. Both quercetin and rutin are used in many countries as medications for blood vessel protection, and are ingredients of numerous multivitamin preparations and herbal remedies.
It has the function of reducing capillary permeability and fragility and also can be used as an adjuvant treatment in preventing hypertension.
