Patent GB-463137-A (GB)
Title: Process for the purification of germinal gland hormones
Filed: 1935-10-07
Abstract: Female sexual hormones are purified or are separated from male hormone by precipitating them from solution in a non-dissociating solvent, such as ether or benzene, by means of a solid alkali metal hydroxide or an alcoholic solution of alkali metal or alkali metal hydroxide, under substantially anhydrous conditions, and separating the precipitate; male hormone, if present, and neutral substances such as cholesterol may be isolated from the filtrate. Free fatty acids may be removed from the initial solution by a preliminary precipitation by means of weaker alkalies such as anhydrous sodium carbonate or oxides, hydroxides or carbonates of calcium or magnesium.  The strong alkali precipitate containing the female hormone may be dissolved in water, extracted with ether to remove the most weakly acid constituents, treated with carbon dioxide and again extracted; or after acidification may be steam distilled to remove lower phenols.  Examples relate to the treatment of a butyl alcohol extract from hydrolyzed mares' urine to obtain female hormone; to the treatment of the portion of the germinal gland hormones esterified with phthalic acid obtained from the urine of mares according to Specification 391,686, to obtain delta-follicle hormone; to the treatment of a chloroform extract of men's urine to obtain male sexual hormone and phenolic hormones; and to treatment of a follicle hormone preparation containing 300,000 M.U. per gram to obtain pure crystalline preparations.
