Introduction of Rutin

Rutin, also known as rutoside or vitamin P, belongs to the class of flavonoids and is widely found in herbs (Sophora japonica, Astragalus, Pueraria lobata, Chenopodium, etc.), fruits, and vegetables. It has pharmacological effects such as antioxidant, anti-inflammatory, antibacterial, antiviral, antidiabetic, and anticancer, etc. Categorized as vitamin P, rutin increases the toughness of capillaries, regulates their permeability, and has lipid-regulating, preventive and therapeutic effects on cardiovascular diseases. It is also used as an active ingredient in pharmaceuticals, multivitamin preparations, cosmetics, animal feed, and chemical industries.

Physical and chemical properties

Rutin is light yellow or light green needle-like crystals or crystalline powder. The color turns dark when exposed to light. Its melting point is 177~178℃. When dried at 95~97℃, it becomes two molecules of crystalline water. Dried at 110℃ under vacuum (1.33×103Pa) for 12h and then become anhydrous. Anhydrous material is easy to deliquescence. It can absorb 2.5 molecules of water in the atmosphere. The solubility of rutin is 0.012% in cold water and 5% in hot water. It is slightly soluble in ethanol. With the function of vitamin P, it can prevent and control the bleeding caused by capillary brittle.

The functions of rutin

  1. Rutin is a vitamin-like drug, which has the effect of reducing capillary permeability and fragility, maintaining and restoring the normal elasticity of capillaries. It can prevent arteriosclerosis. Together with hesperidin and eriodictin, it acts as a vitamin P substance.
  2. It has a good anti-radiation and anti-free radical effect on the skin. Rutin has an extremely strong absorption effect on UV and X-rays. As a natural sunscreen, adding 10% rutin, the UV absorption rate is up to 98%.
