Description
Technical field
The invention belongs to biomedicine technical field, relate to the preparation method of ursodesoxycholic acid, the method being specifically related to prepare ursodesoxycholic acid with Fel Sus domestica for raw material.
Background technology
The product that bile is human body or vertebrate liver cells is secreted continuously, it is a kind of viscosity color-alkali liquid with bitterness, its composition than water, mainly has bile acid, cholate and bile pigments, in addition with a small amount of cholesterol, fatty acid, lecithin, electrolyte and protein etc..Animal bile the most more typically is generally bird gall, Fel Sus domestica, Fel Bovis seu Bubali, Fel Ursi and Fel Serpentis etc..Bile acid is the main component of bile, account for the 50% ~ 70% of bile total amount, the physiological action of bile is mainly played by bile acid exactly, when as medicine, bile acid can be used to antipyretic, spasmolytic antitussive, regulation blood pressure, heart tonifying function of gallbladder promoting, antibacterial anti-inflammatory and regulation immunity etc., and activity is relatively strong, side effect is the least, cheap, therefore suffers from the welcome of vast medication person.
In various animal biles, Fel Sus domestica is most common and yield is maximum, start just to be widely used in clinic from ancient times, as with Fel Sus domestica treatment acute icteric infectious hepatitis, pertussis, acute enteritis and gastric ulcer etc., good therapeutic effect all can be received.Mainly containing bile acids, bile pigments, mucin, lipid and inorganic matter etc. in Fel Sus domestica, bile acid mainly comprises Hyodeoxycholic Acid, hyocholic acid, chenodeoxycholic acid, 3 Alpha-hydroxy-6-oxygen-5 α-cholanic acid and cholelithiasis acid etc..Wherein Hyodeoxycholic Acid accounts for 40%, and chenodeoxycholic acid accounts for 25%.
Ursodesoxycholic acid entitled 3 α of chemistry, 7 β-dihydroxy-5 β-cholanic acid, molecular formula C24H49O4, molecular weight is 392.58, for white or micro-yellow powder, is soluble in ethanol, glacial acetic acid, is slightly dissolved in chloroform, be practically insoluble in ether and water.Ursodesoxycholic acid is first to find from Fel Ursi for 1920, and Shoda isolated crystal from Fel Ursi in 1927 determines its chemical constitution in 1937.Natural ursodesoxycholic acid derives from Fel Ursi, and along with the demand of clinical practice is continuously increased, natural ursodesoxycholic acid can not meet far away the market demand.Kill Bears to take gallbladder and prohibited by country, therefore, obtain ursodesoxycholic acid by chemical synthesis process and become more and more important.Initially, people's success, with cholic acid, deoxycholic acid etc. as raw material, has synthesized ursodesoxycholic acid, but this kind of method reactions steps is many, and complex process, productivity is low, is difficult to carry out industrialization large-scale production.
In recent years, with chenodeoxycholic acid as raw material, carry out chemosynthesis ursodesoxycholic acid technical process and be greatly simplified.And chenodeoxycholic acid is the Main Ingredients and Appearance of the poultry bile such as chicken, duck and goose, directly can extract from duck, goose and the bile of chicken and obtain, mature production technology, cheap.Therefore, with chenodeoxycholic acid for raw material production ursodesoxycholic acid, Fel Sus domestica particularly extracts from originating after chenodeoxycholic acid chemosynthesis ursodesoxycholic acid widely again, obvious economic benefit and social value can be created.
Summary of the invention
The technical problem to be solved is to provide a kind of method preparing ursodesoxycholic acid for raw material with Fel Sus domestica, and the method extraction process is simple, and raw material sources are extensively easy to get, and environmental pollution is little, and product purity is high.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is as follows:
The method preparing ursodesoxycholic acid for raw material with Fel Sus domestica, comprises the steps:
(1) chenodeoxycholic acid is prepared: with Fel Sus domestica as raw material, extract the mother solution after bilirubin and prepare TOTAL BILE ACID TBA, add and adjust pH to 7.2~7.5 with sodium hydroxide after ethanol dissolves, add calcium chloride solution to precipitation completely, water washing and precipitating obtains CDCA acid calcium salt, adding 50% propanoic acid or 60% acetic acid, at a temperature of 40~50 DEG C, heating makes it be completely dissolved, and adds and i.e. separates out chenodeoxycholic acid in water;
(2) oxidation: chenodeoxycholic acid is dissolved in the mixed solution of acetone and water, adds weak oxidant, make chenodeoxycholic acid be converted into 7-O-lithocholic acid;
(3) reduction: with sec-butyl alcohol as solvent, metallic sodium is reducing agent, at reflux, the 7-O-lithocholic acid of step (2) is reduced to ursodesoxycholic acid and chenodeoxycholic acid mixture;
(4) purification: the ursodesoxycholic acid of step (3) and chenodeoxycholic acid mixture are placed in organic solvent, react with silication agent at a temperature of 75~85 DEG C, generate ursodesoxycholic acid silicon ether solid precipitation, then by this solid at a temperature of 40~50 DEG C with acid reaction, obtain ursodesoxycholic acid sterling.
As the improvement of the present invention, the weak oxidant of above-mentioned steps (2) is N-bromo-succinimide, and its consumption is 1~5wt%.
Further improve as the present invention, above-mentioned steps (4) organic solvent is benzene, toluene, Nitrobenzol, chloroform, dichloromethane, carbon tetrachloride and oxolane one or more.
Further, the acid of above-mentioned steps (4) is 5~10% sulphuric acid or 5~10% hydrochloric acid.
The silication agent of above-mentioned steps (4) is two replacements or trisubstituted alkyl silicon halogenide, two replacements or trisubstituted silicon urea or dialkyl group silicon amide, preferably dimethyl-silicon amide.
Compared with prior art, the invention have the benefit that
The present invention is using Fel Sus domestica as extracting raw material, and Fel Sus domestica raw material is extensively easy to get, and reduces preparation cost, and income is higher, and economic benefit is good;When the present invention is with chenodeoxycholic acid synthesis ursodesoxycholic acid, with calcium chloride as precipitant, it is to avoid the environmental pollution that conventional barium salt precipitant causes, also simplify precipitation operation simultaneously.
