is a pale yellow or light green needle-like crystal or crystalline powder. Usually there are three water of crystallization, in the case of 95~97 deg C drying lost two water of crystallization, drying at 110 deg C/1. 33kPa under the condition of 12h can become anhydrous. The anhydrous became Brown at 125 °c, flexible and plastic at 195-197 °c, and decomposed at 214-215 °c. The specific optical rotation was 13. 82 °c (ethanol as solvent). Rutin structure in the presence of four phenolic hydroxyl groups, so its aqueous solution encountered Fe3 blue green. Anhydrous material is easy to absorb moisture, almost insoluble in water, chloroform, ether, benzene, carbon disulfide and petroleum ether, soluble in pyridine, DMF and alkaline aqueous solution, slightly soluble in ethanol, acetone and ethyl acetate. With the function of vitamin P, can prevent capillary fragility caused by hemorrhagic disease.
rutin is a kind of flavonol glycoside compound with wide source, which exists in plants, especially in Sophora japonica and Sophora japonica. Generally tartary buckwheat leaves, flower buds of Sophora japonica (Sophora japonica), red beans and other raw materials. The extraction methods include ethanol extraction, hot water extraction, hot alkali solution extraction, cold alkali solution extraction and sodium sulfite hot alkali solution extraction.
It can be used as an edible antioxidant and a nutrition enhancer. With the maintenance of vascular resistance, reduce its permeability, reduce the role of brittleness. Can be used for the prevention and treatment of cerebral hemorrhage, hypertension, retinal hemorrhage, purpura and acute hemorrhagic nephritis and other diseases.
Sophora japonica L. Is the flower bud of Sophora japonica L., which is like a rice grain when the flower is not opened. It is very fresh and stained with fried water. Sophora japonica has the function of cooling blood to stop bleeding, clearing liver and purging fire. For blood in the stool, hemorrhoidal blood, blood dysentery, bleeding, hematemesis, blood, liver and red eyes, Head Pain vertigo. Most of the processing is raw, saute or fried charcoal.
when the summer flower is not open, the flower bud is harvested, the impurity is removed, and the sun is exposed. Medicinal herbs are mainly produced in Hebei, Shandong, Henan, Jiangsu, Guangdong, Guangxi, Liaoning, most parts of the country.
The flower bud is ovoid or oblong, 2.5~1.5 in length and ~ in width; It is yellowish brown or yellow-green in appearance, slightly retracted, with a bell-shaped Calyx in the lower part, apex with less pronounced 5-dentate fissures, sometimes short-stalked, upper one with an unopened crown, varying in size, with sparse white pubescence outside the calyx and the Crown. Friable. The taste was slightly bitter. The flower bud foot strong, Calyx color green and thick, no branch stem is better.
Sophora japonica and Sophora japonica contain basically the same components, mainly containing triterpenoid saponins, red bean saponins, soybean saponins, Sophora japonica saponins. It also contains flavonoids, quercetin, rutin, isorhamnetin, isorhamnet-3-target glucosides, kaempferol -3-rutin. It also contains betulin and Sophora japonica diol. Flower oil contains lauric acid, dodecenoic acid, myristic acid and other fatty acids and β-sitosterol. It also contains tannin.
troxerutin, also known as venoruton, is one of the most important rutin derivatives. It is a semi-synthetic water-soluble flavonoid compound made by hydroxyethylation of rutin, which has good curative effect on occlusive vascular disease, is a better treatment of occlusive cerebrovascular disease drugs. It can inhibit platelet aggregation, prevent thrombosis, increase blood oxygen content, improve microcirculation, promote angiogenesis, increase the role of collateral circulation. At the same time, it has a protective effect on endothelial cells, can resist the vascular injury caused by serotonin and bradykinin, increase the Capillary resistance, reduce the capillary permeability, and prevent the edema caused by the increase of vascular permeability. Pharmacological experiments show that this product has a significant protective effect on acute ischemic brain injury. Clinical troxerutin can be used for the treatment of cerebral thrombosis and cerebral embolism caused by hemiplegia, aphasia and myocardial infarction syndrome, arteriosclerosis, central retinitis, thrombophlebitis, varicose veins, edema caused by increased vascular permeability.
rutin is a kind of Vitamin p, which is the glycoside of dehydroflavone ketone. It is a hydrogen transporter that may be involved in the action of oxidoreductases in the body, which can affect the activity of the thyroid gland and protect epinephrine from oxidation. In the body can enhance the role of vitamin C and promote its accumulation in the body. Can maintain vascular elasticity, reduce its permeability, reduce its fragility. The mechanism is that hyaluronic acid is a matrix component in the intercellular substance of capillary wall. When it is hydrolyzed by hyaluronidase, the resistance of capillaries is reduced, the permeability and brittleness are increased, and bleeding is easily caused. Rutin can inhibit hyaluronidase, prevent hyaluronic acid hydrolysis, thereby enhancing the resistance of capillaries, reducing its permeability and brittleness. Rutin also promote cell proliferation, prevent blood cell agglutination, and diuretic, antitussive, hypolipidemic, antihypertensive, protective ulcer surface, anti-inflammatory and anti-allergic effect.
yellow small needle-like crystals (by Crystal Analysis). The color turned darker in light. Bitter taste. The melting point was 177-178 °c. Drying at 95-97 °c results in two molecules of crystalline water. After drying at 110 °c under vacuum (1.33 x 103Pa) for 12h, the product is anhydrous. Anhydrous easy deliquescence, melting point 190~192 ℃, in the atmosphere can absorb 2.5 molecules of water. In cold water solubility of 0.012%, hot water solubility of 5%. Slightly soluble in ethanol.
It has the function of normal blood vessel wall in animals. Can prevent arteriosclerosis. Together with hesperidin, the grass, as a vitamin P role of substances.
It is found in rutwood, buckwheat, Sophora japonica buds, tobacco leaves, leaves of Catalpa bungei, stems and leaves of tomato, etc. The content of the dried wheat at the time of flowering is about 3%.

There are several mechanisms of skin aging: the collagen theory holds that skin aging is caused by the polymerization of collagen in the skin, but the reaction rate is greatly accelerated under ultraviolet light irradiation, resulting in accelerated skin aging. According to the theory of free radicals, skin aging is the result of the generation and elimination of free radicals, which can increase the formation of oxygen free radicals and cause a series of changes in skin under pathological or ultraviolet irradiation, for example, skin collagen fibers and elastic fibers lose elasticity and break, resulting in wrinkles, generation of melanin and generation of color spots.
rutin has a strong absorption of ultraviolet and X-ray. As a natural sunscreen, adding 10% rutin, the absorption rate of ultraviolet is as high as 98%.
oxygen molecules are reduced in the form of single electron in Cell Metabolism, oxygen molecules in the single electron reduction to produce O ions, the body then produces H2O2 and highly toxic · OH radicals, therefore, it affects the smoothness of the skin and even accelerates the degree of skin aging. The addition of rutin to the product can obviously remove the active oxygen radicals produced by the cells, and the clearance rate of Oi is as high as 78.1%, far greater than the effect of vitamin E(12.7%), but also on the OH scavenging effect is greater than that of vitamin E.
