    hesperidin diosmin

       hesperidin diosmin, hesperidin one of the vitamin P flavonoids is mainly found in citrus fruit, especially in the peel of citrus, orange, sweet orange and lemon.The extracted hesperidin product is white powder and minute needle crystal.Hesperidin is an important component of vitamin P and plays a role in softening blood vessels.
       It has the function of reducing fragile capillaries, protecting capillaries and preventing microvascular rupture and hemorrhage.Is the treatment of hypertension and myocardial infarction drugs, the pharmaceutical industry used as raw materials, is one of the main components of the patent medicine.
    Because hesperidin inhibits the activity of enzymes involved in cholesterol synthesis, it reduces blood lipids.People with high blood cholesterol were given three glasses of orange juice a day for.
        Melting point is 251 ℃.Than the polarimetric = - 76 ° pyridine solution (2%).Insoluble in ether, benzene, insoluble in chloroform, acetone, water, slightly soluble in ethanol, methanol, slightly soluble in hot acetic acid, aniline, soluble in pyridine, glycerine, dilute alkali solution.After adding iron trichloride to the ethanol solution, the solution was dark brown.When reduced with magnesium powder and hydrochloric acid, it is purplish red.Hesperidin was yellow in lye and its solubility increased with pH value.When pH decreases, dissolved hesperidin precipitates out to form a white turbid precipitate, which is the main component of the white precipitate in citrus tins.The higher the maturity of the raw material, the lower the content of hesperidin.When heated under acidic conditions, hesperidin gradually hydrolyzes to form glucose, rhamnose and hesperidin.The anti-inflammatory effect of hesperidin may be achieved by inhibiting the release of histamine.
