摘要： A process for preparing a high-melting form of CDCA having a melting point of at least about 160.degree. C. is disclosed which comprises the steps of:(a) suspending at least one form of CDCA having a melting point of below 160.degree. C. in a non-aromatic liquid hydrocarbon, preferably cyclohexane, to form a suspension having a boiling point of at least 65.degree. C.;(b) heating the suspension to a sufficiently high temperature of between about 65.degree. and about 140.degree. C., preferably between about 75.degree. and about 100.degree. C., during a sufficiently long period of time for converting substantially all of the CDCA into the high-melting form;(c) recovering the high-melting form of CDCA from the suspension.Low-melting amorphous and/or crystalline forms of CDCA, as well as CDCA-solvent inclusion complexes can be treated in the above-described process. The high-melting CDCA is obtained in form of a substantially granular powder, which is suitable to be formulated into therapeutical compositions.

摘要： A method of isolating chenodeoxycholic acid from hog bile is provided, which comprises the steps of treating the hog bile under saponifying conditions separating the bile acids from the water-soluble constituents of the saponified bile; esterifying the bile acids to obtain a mixture of bile acid esters; isolating from the mixture of bile acid esters the hyodeoxycholic acid ester as its adduct with a compound selected from the group consisting of benzene and toluene; treating the remaining bile acid esters under acetylating conditions; isolating the hyocholic acid ester triacetate; isolating the chenodeoxycholic acid ester diacetate; treating the chenodeoxycholic acid ester diacetate under saponifying conditions; isolating the chenodeoxycholic acid thus obtained; and, optionally purifying the chenodeoxycholic acid.The method described yields chenodeoxycholic acid of exceedingly high purity, which may be used in the treatment of gallstones by their dissolution in vivo.
