Title: A process for preparing vitamine-a in free or combined condition
IPC: A61K31/59
Filed: 1929-02-18
Abstract: 306,881. Shimizu, T. Feb. 18, 1929. [A Specification was laid open io inspection under Sect. 91 of the Acts, Feb. 27, 1929]. Vitamins.-Vitamin A is extracted from suitable materials such as egg yolk, cod liver oil, tomato, spinach, and green algae, by removing cholesterol and the like from the uusaponifiable portion, and precipitating the vitamin as a choleic acid from which the free vitamin mav be obtained. In an example, cod liver oil is saponified with alcoholic potash and alcoholic solution of an alkaline earth salt such as calcium .chloride is added, the precipitated alkaline earth soaps being removed. The filtrate is treated with an acid such as carbonic acid to convert any free inorganic base into insoluble salts such as carbonates or bicarbonates, which are removed. The alcohol is then evaporated, and the residue dissolved in a solvent immiscible with water such as acetic ester, benzene, or ether. The solution is washed with soda, trisodium phosphate &.c. to remove acids, then with water or dilute acids such as hydrochloric or sulphuric acid, and is then evaporated to remove the solvent. The oily partly crystalline residue is dissolved in a small quantity of an organic solvent such as methyl or ethyl alcohol, acetone, or ethyl acetate and cooled to crystallize out cholesterol. The mother-liquor is evaporated and the dark brown oil which separates is dissolved in a suitable solvent such as methyl or ethyl alcohol or acetone, and desoxycholic acid or other bile acid adapted to form choleic acids (such as apocholic or bufodesoxycholic acid) is added. To cause the evaporation of a choleic acid the solution may be heated or evaporated and taken up in the same solvent, repeatedly if necessary. Water is added with stirring until the fluorescence disappears and the solution remains clear when warm. On cooling the vitamin A choleic acid crystallizes, the mother-liquor containing other vitamins such as D and E, which mav be recovered from it. The crvstals are allowed to stand in contact with ether, chloroform, or the like to purify them, and have the empirical formula (C24H40O4)5. C27H44O2.H2O. To obtain the free vitamin, the choleic acid may be boiled with a large excess of a substance which forms a choleic acid, such as xylol, glacial acetic acid, or a fatty acid. On cooling the xylol choleic acid crystallizes out. The mother-liquor is freed from xylol by evaporation and the residue is taken up in the methyl or ethyl alcohol, acetones, esters, &c. On evaporation the vitamin separates in white needles of the formula C27,H44O2. Alternatively, the choleic acid may be distilled at 250‹ C. in a high vacuum. the distillate being dissolved in a small quantitv of a solvent such as alcohol and the solution concentrated and allowed to crystallize. The crystals of the vitamin A choleic acid and of the free vitamin A are relatively stable to oxygen. but the process is effected in absence of free oxygen, for instance in a nitrogen atmosphere.
