Rutin, also called rutoside, is the glycoside combining the flavonol quercetin and the disaccharide rutinose.


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

Molecular Formula : C27H30O16

Molecular Weight : 610.51

Specification : EP, NF11, DAB10

Appearance : Yellow or greenish-yellow crystalline powder.




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

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.
