| Physical and Chemical Properties | Light green yellow or light yellow viscous liquid, basically tasteless, the relative density of 0.947~0.955. Insoluble in water, but soluble in ethanol, gasoline, ethyl esters and vegetable oils. It is stable to heat and almost does not decompose when heated to 200 ℃; It is stable to oxygen in air, but it undergoes slow oxidation, and the oxidation resistance of the synthesized product is weaker than that of the natural product. The color of the visible light gradually darkened. |
| Use | It is used for the Prevention of abortion, habitual abortion and threatened abortion caused by vitamin E deficiency, and also for the treatment of infertility and infant nutritional giant cell anemia. |
| Introduction | Natural Vitamin E is a brownish red or transparent light yellow oily liquid with a mild, special odor and taste. Soluble in ethanol, acetone, ether, chloroform or vegetable oil, almost insoluble in water. High boiling point (250 ° C), stable to heat. It becomes dark red when exposed to air and light. It has no heat and does not participate in human metabolism. |
| Food sources | Natural Vitamin E is widely found in plants and animals in nature, and can be extracted from a variety of plant oils, leafy vegetables, animal organs and substances relatively rich in Tocopherols and Tocotrienols are extracted. At present, Natural Vitamin E mainly comes from vegetable oils and their products. |
| physiological function and role | vitamin E(VE) including α, β, δ, gamma tocopherol and the corresponding tocotrienols and other 8 kinds of substances, belonging to the fat-soluble vitamins, with anti-free radicals, anti-aging, prevention of skin keratinization, improve human and animal physical immune function and cellular immune function, prevention and treatment of cardiovascular and cerebrovascular diseases and other important physiological functions. VE has two major sources of natural vitamin E and synthetic VE. Natural Vitamin E is a mixed tocopherol containing a variety of monomers, but Natural Vitamin E is superior to synthetic VE in both physiological activity and antioxidant capacity, and natural vitamin E on the human body non-toxic side effects, so in food, nutrition and health products and cosmetics and other industries, Natural Vitamin E by the majority of consumers of all ages. |
| deficiency | 1. Hemolytic anemia. Because vitamin E is rarely delivered to the newborn through the placenta, vitamin E is low in the plasma of newborns or premature infants. If the mother is lack of vitamin E, vitamin E deficiency in young children will lead to children easily rupture of blood cells and anemia, known as hemolytic anemia, sometimes indirectly lead to yellow bile. 2. Gastrointestinal discomfort, impotence, edema, skin disease, muscle weakness. 3. Chronic fat malabsorption. 4 hemolysis, muscle uric acid, smooth muscle brown pigment precipitation. 5. Bladder fibrosis, thrombocytosis, hair loss, dry hair. In adults with vitamin E deficiency for many years, there is an increase in the dissolution of red blood cells. 7. Menstrual disorders, end-point blood circulation disorders caused by cold virtual hands and feet, frostbite. Cold sensation. |
