Description

Water-soluble vitamins D 2The preparation method
Technical field
The present invention relates to vitamins D 2Field, particularly water-soluble vitamins D 2The preparation method field.
Background technology
Vitamins D 2Be that humans and animals is kept normal activities and one of healthy necessary micro-organic compound, can add vitamins D in right amount in medicine, food and the feed 2Satisfying the human or animal absorbs from the external world regularly.Vitamins D 2It is the main natural form of the vitamins D in plant, found.(referring to Chinese patent 95118188.2).And VITAMIN is divided into two classes according to its solubleness is liposoluble vitamin (A, D, E, K) etc., or water-soluble vitamins (B 1, B 2, B 6, B 12, folic acid, nicotinic acid and vitamins C)] etc.[see " pharmaceutical chemistry " the 15th chapter, one, the classification of VITAMIN (the refined rosy clouds of the central TV university farming doctor king of portion).Because vitamins D 2Water insoluble and be dissolved in fat and fatsolvent, therefore often in food coexist with lipid, also closely related when intestinal absorption with the absorption of lipid, as human or animal during to the malabsorption of lipid, liposoluble vitamin D 2Absorption can reduce, thereby cause corresponding deficiency disease.At vitamins D medically 2Principal indication comprise three aspects, one, be used for the prevention and the treatment of vitamin D deficiency.As: vegan, parenteral nutrition patient, pancreatic insufficiency companion malabsorption syndrome, liver and gall diseases (hepatic disorder, liver cirrhosis, obstructive jaundice), disease of intestine (pimelorrhea, regional enteritis, long-term diarrhea), stomach excision etc.Two, be used for chronic hypocalcemia, hypophosphatemia, rickets and with the treatment of osteomalacia, familial hypophosphatemia and the hypoparathyroidism (postoperative, special property or the Pseudohypoparathyroidism sent out) of chronic renal insufficiency.Three, be used for the treatment of acute and chronic and potential operation back tetany disease and the special property sent out tetany disease.And the animal vitamins D 2The feature of deficiency disease show as: vitamins D 2When not enough, even calcium, phosphorus abundance, animal can not well utilize, and calcium, phosphorus, the magnesium deposition in bone can descend; Hypoplasia of tooth, growth retardation rickets and rickets appear, in the osteogenesis generation obstacle of young animal; Adult animals generation osteoporosis is easily fractured joint deformity; Dam pregnancy period vitamins D 2Excessively shortage can cause newborn young baby's congenital malformation, and dam itself also can suffer damage; The poultry D that is deficient in vitamin 2Can reduce egg productivity and hatching rate, eggshell approaches and easily embrittlement.Therefore under the condition of the artificial mass rearing animal of modern mechanicalization, more need vitamin D Can 2Yet excessive use vitamins D 2Be deleterious, take in heavy dose in a short time or take the overdose vitamins D for a long time according to relevant medical information prompting 2, can cause serious toxic reaction.Vitamins D 2The hypercalcemia of poisoning and to cause can cause general angiosteosis, kidney marl and other soft tissue calcifications, and hypertension induced and renal failure, and above-mentioned untoward reaction pilosity is born in hypercalcemia and during with hyperphosphatemia.Children can cause cessation of growth cessation, see the prolonged application vitamins D repeatly 2Behind every days 1800 units, toxic dose can be different because of individual difference.Even use 10,000 units every day above after the several months, to also intoxicating reaction of normal adult.Vitamins D 2Poisoning can cause death because of kidney, cardiovascular function depletion.Animal pregnancy excess intake vitamins D 2Can cause the young deformity of tire, the animal vitamins D 2Poisoning manifestations is higher urinary calcium, apocleisis, nausea and vomiting, thirsty, diuresis, weak, arthralgia and general disorientation, excessive vitamins D 2Causing that blood calcium is too high makes unnecessary calcium be deposited on heart, blood vessel, joint, pericardium or intestines wall, causes heart failure, ankylosis or enteron aisle illness, in addition dead.Two kinds of principal modes of vitamins D are vitamins Ds 2And vitamins D 3, it is generally acknowledged that they demonstrate similar biological activity, the same metabolism (i.e. activation and katabolism) is arranged, but have data to think; " vitamins D 310~20 times of toxicity to vitamins D 2, this is because vitamins D 3Be easy to be metabolised to 25-hydroxyl-D 3Reason, Trunnel etc. (1990) feed vitamins D, A and E mixture for the milk calf of 15 7~10 ages in days and cross-bred ox, every day Dry Vitamin D3 100 cws 000,000 units, vitamin-E 880,000 units.All as a result oxen all show lassitude, apocleisis, depilation, symptoms such as dysbasia, wherein 6 death after feeding 13~27.To wherein 3 its row dissection discoveries, at Pulmonic internal surface the reddish-brown precipitation thing is arranged, the liver light discolouration.6 oxen in 8 oxen are carried out blood chemical examination, find 25-hydroxyl-D in the blood plasma 3And calcium 2+Concentration obvious rising is all arranged." (referring to people such as " security of liposoluble vitamin additive " author Huang Tao, Chen Xibin, Sheng Jinpeng, Chinese culturing net).According to State Standard of the People's Republic of China GB14880-94 " food enrichment use hygienic standard " to vitamins D (D 2Or D 3) use range and per kilogram usage quantity be defined as; Breast and milky-drinks 10~40 μ g, oleomargarine 125~156 μ g, milk-product 63~125 μ g, infant or baby food 50~100 μ g (1 μ g vitamins D=40 unit vitamin D).And be vitamins D (IU/kg) for vitamins D as the national standard of safe feeding addition, pig 114-240, chicken 200~500, duck 400~900.Because the consumption of vitamins D is a unit with μ g, liposoluble vitamin D 2When mixing, be difficult to the control consumption and be difficult for mixing and cause product defective, therefore, add vitamins D in domestic food or the feedstuff industry with food or feed 2Product few.Vitamins D 2Be about 1800 tons at present global year consumption, wherein about 70% are used for fodder additives.China's annual requirement is about more than 100 ton.Present global vitamins D 2Market is learned company and is controlled by BASF AG, Roche Holding Ag, day Qinghua, mainly supplies Europe and Japanese market, and these VITAMIN are made giant in the VITAMIN in the whole world is sold, and are sold to terminal client by multidimensional and Preblend more than 40%.The retrieval novelty assessment report that provides according to patent information center, Sichuan Province shows through the result for retrieval to China and foreign countries' patent database still to find no water-soluble vitamins D 2The technical information of aspect.
Goal of the invention:
The objective of the invention is at liposoluble vitamin D 2The problems referred to above that exist adopt emulsifying agent with liposoluble vitamin D 2(medical grade, food grade vitamins D 2, or with ergosterol through irradiation make 9,10 bond ruptures and vitamins D 2Crude product), make the water-soluble water-soluble vitamins D of energy 2Method:
Summary of the invention
Water-soluble vitamins D of the present invention 2The preparation method, carry out as follows:
