Production method and application of vitamin D2
Vitamin D2, in turn, is called a calciferol, which is mainly stored in the liver and the fat, which is metabolized and activated first through the liver, followed by the kidney. The vitamin D2 is a colorless needle-like crystal or a white crystalline powder, and has no odor, no odor, and can be easily deteriorated in the event of light or air.
Production method of vitamin D2 (/)
1. Ergosterol was dissolved in ethanol. The reaction solution was condensed, frozen and filtered by UV irradiation. Filtrate liquid nitrogen, concentrate to dry under pressure, get vitamin D 2 crude oil, get finished product after refining.
2. Vitamin D2 naturally exists in liver, milk and egg yolk. In industry, ergocystol, soluble in chloroform or cyclohexane, is often extracted from vegetable oil or yeast and converted into vitamin D2 by ultraviolet irradiation.
And (3) dissolving ergoline, such as beer yeast, lentinus edodes and the like, in a solvent such as chloroform, diethyl ether or cyclohexane, adding into a flask made of quartz glass, and irradiating with ultraviolet rays.
Indications for vitamin D 2 (/)
use: large doses are also used for skin tuberculosis, skin and mucosal lupus erythematosus. Vitamin D 3 can regulate cell growth, including inducing normal cell differentiation and inhibiting cell proliferation.
The material comes from the network.
