Chemical Properties:
  1. Ergocalciferol, also under the name vitamin D2, is a type of vitamin D found in plants and yeast. It has no antirachitic activity. It helps the body to absorb calcium and phosphorus. It is used as a dietary supplement. It is used in the treatment of hypoparathyroidism (a condition in which not enough parathyroid hormone can be produced by the body), refractory rickets (softening and weakening of bones that does not respond to treatment, it is also known as vitamin D resistant rickets), and familial hypophosphatemia (rickets or osteomalacia caused by an inherited condition with a decreased ability to break down vitamin D in the body). Ergocalciferol is also used as a rodenticide.
  2. Vitamin D refers to a group of fat-soluble steroid compounds with anti-rickets effect and is called anti-rickets vitamin. It is known currently about at least ten or more sterols substance with vitamin D activity. They are mainly presented in the vegetable oil or yeast ergosterol solid which subject to sunlight or ultraviolet irradiation to generate vitamin D2 which is also called as calciferol or ergocalciferol. Therefore, ergosterol is also called as original vitamin D2; the other is from that the human body can convert the cholesterol to the 7-dihydro-cholesterol to be stored in the skin with the later being able to be converted to vitamin D3 upon sunlight and ultraviolet radiation. Vitamin D3 is also known as cholecalciferol and therefore the 7-dehydrocholesterol is also known as original vitamin D3. Vitamin D2 has a very similar structure with vitamin D3 and both of them are the B ring open-ring derivatives of precursor sterols with the difference of them being laid in a extra double bond and a methyl group in the side chain of vitamin D2.
Application:
  1. Vitamin D2 can be applied to biochemical studies; its clinical drug belongs to a lipid-soluble vitamin which can promote the intestinal absorption of calcium and phosphorus which plays a role of facilitating the calcification of bone. It is clinically used for prevention and treatment of rickets in children and adult osteomalacia.
    Vitamin D2 can maintain the normal metabolism of calcium and phosphorus and can also promote the body’s absorption of calcium and phosphorus. Upon its deficiency, the children are easy to get rickets. China ruled that it can be applied for strengthening margarine with the usage amount being 125~156 μg/kg; its usage amount in fortified dairy is 63~125μg/kg; the usage amount in strengthening infant and children food used is 50~100μg/kg; the usage amount in strengthening milk or milk beverage is 10~40μg/kg; the maximal allowable usage amount in the strengthening solid drinks and ice cream is 10~20μg/kg.
