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 function of reducing capillary permeability and fragility and also can be used as adjuvant treatment in preventing hypertension.

Troxerutin also called Venoruton, Vitamin P4, is classified as bioflava-noid. It is a derivate of Rutin through hydroxyethylation, able to use directly as API. It can be used to the treatment of varication, thrombo-sis and cerebrovascular disease, thrombosis has better water-solubility and drug effect than Rutin.

Troxerutin is useful in inhibiting aggregation of red blood cells and platelets, preventing thrombogenesis, increasing blood oxygen content and promoting neovascularity at the same time.

It can also build up capillary resistance, lower capillary permeability, so that to prevent edema caused by increasing capillary permeability. It is with more functions, such as anti-radiation lesion, anti-inflammato-ry, anti-allergic, anti-ulcer, etc

Quercetin is a flavonoid widely distributed in nature. It is a potent antioxidant and has anti-inflammatory activity, protecting cellular structures and blood vessels from the damaging effects of free radicals.

It improves blood vessel strength. Quercetin inhibits the activity of catechol-O-methyltransferase that breaks down the neurotransmit-ter norepinephrine. This effect may lead to elevated levels of norepine-phrine and an increase in energy expenditure and fat oxidation.
