Alias: Rutin; Rutin; Vitamin P
Rutin is a vitamin drug, which has the function of reducing capillary permeability and brittleness, maintaining and restoring the normal elasticity of capillaries. It is used for prevention and treatment of hypertensive cerebral hemorrhage, diabetic retina hemorrhage and hemorrhagic purpura, etc. it is also used as food antioxidant and pigment. Rutin is also the main raw material for the synthesis of rutin. The use of krutin for cardiovascular and cerebral blood vessels can effectively inhibit the aggregation of platelets and prevent thrombosis.
It is mainly finished by alcohol extraction, extraction, chromatography, crystallization and so on.

Causes of skin aging
There are several mechanisms of skin aging: collagen theory that skin aging is caused by the polymerization of bone gelatin in the skin, but the reaction speed is greatly accelerated under ultraviolet light, causing the accelerated aging of the skin. The free radical theory holds that skin aging is the result of the formation and elimination of free radicals. In pathology or ultraviolet radiation, the formation of oxygen free radicals can be increased, causing a series of changes in skin, such as the loss of elasticity and fracture of the skin collagen fibers and elastic fibers and wrinkles, the formation of melanin and the production of color spots.
Rutin has a strong absorption of ultraviolet and X rays. As a natural sunscreen, adding 10% rutin, the UV absorptivity is as high as 98%.
Anti free radical action
Oxygen molecules are reduced in the form of single electron in cell metabolism. Oxygen molecules are produced by single electron reduction of O ions. In the body, H2O2 and toxic OH radical are produced in the body. Therefore, the tender degree of skin is affected and even the skin aging is accelerated. The scavenging rate of oxygen free radicals and Oi was 78.1%, far higher than that of vitamin E (12.7%), and the scavenging effect on OH was also greater than that of vitamin E.
