Description
Technical field
The present invention relates to the chemical engineering stripping technique, especially relate to a kind of solvent crystallization purifying 3 β-courage steroid-5, the method for 24-diene-3-alcohol.
Background technology
3 β-courage steroid-5; 24-diene-3-alcohol (3 β-cholesta-5; 24-dien-3-ol; Desmosterol is to extract a kind of sterols material that obtains serum, liver and some other animal tissuess from blended plant sterol, marine alga, animal CAS:313-04-2), is the biosynthetic direct precursor of SUV.Domestic and international research is verified, 3 β-courage steroid-5, and 24-diene-3-alcohol not only has some physiological actions of SUV; Also in mammiferous sexual maturity, played vital role; Sperm motility also there is material impact, 3 β-courage steroid-5,24-diene-3-alcohol also is important medicine intermediate simultaneously; Can be used as many synthetic initial feed, such as moulting hormone with sterol of physiologically active.Therefore, 3 β-courage steroid-5,24-diene-3-alcohol has important economic value.
3 β-courage steroid-5,24-diene-3-alcohol can carry out complete synthesis or semi-synthetic (U.S. Pat 3846455, J.Org.Chem.1958 through organic reaction; 23,459), but production cost is higher; Less economical, and used more soda acid solvent, be prone to environment is produced pollution.
3 β-courage steroid-5,24-diene-3-alcohol also can obtain by extraction separation from plant-animal.Usually the solvent extraction techniques that adopts can obtain 3 β-courage steroid-5, the bullion of 24-diene-3-alcohol, but 3 β-courage steroid-5, and 24-diene-3-alcohol purity is lower, generally below 10%, does not meet commerce with requiring, and therefore need be further purified processing.
Raw material influences later separation method and cost, and U.S. Pat 3803184 adopts solvent extraction-aluminum oxide chromatogram-acetylization reaction-AgNO
3Complexing chromatogram-chromatography-multistep methods such as saponification obtain 3 β-courage steroid-5 from the separation of wild rubber seeds, 24-diene-3-alcohol, and this method must be with 3 β-courage steroid-5, and 24-diene-3-alcohol is acetylization reaction in advance, adopts the AgNO of costliness then
3The complexing chromatogram changes into 25 hydroxycholesterols with mercury salt again, and chromatography or the crystallization again of 25 hydroxycholesterols, saponification just can obtain higher degree 3 β-courage steroid-5; 24-diene-3-alcohol, its method is comparatively loaded down with trivial details, and the production cycle is long; And 3 β in wild rubber seeds-courage steroid-5; 24-diene-3-alcohol content is low, and production cost is bigger, is not suitable for industriallization.
Summary of the invention
The object of the present invention is to provide solvent crystallization purifying 3 β-courage steroid-5; The method of 24-diene-3-alcohol; From yolk, extract the 3 β-courage steroid-5 obtain, the process for purification of 24-diene-3-alcohol, through adopt different solvents repeatedly crystallization process from 3 β-courage steroid-5; Separate and prepare high-content 3 β-courage steroid-5 in 24-diene-3-alcohol bullion, 24-diene-3-alcohol.
For realizing the object of the invention, adopt following technical scheme:
3 β-courage the steroid-5 that obtains with extraction separation in the yolk; 24-diene-3-alcohol bullion is a raw material, 3 β-courage steroid-5 wherein, and 24-diene-3-alcohol content is 40-70%; Major impurity is the grease and the triterpene alcohol of polar lipid acid, Fatty Alcohol(C12-C14 and C12-C18), sterol and low-pole.Crystallization may further comprise the steps:
