Abstract:In order to obtain the ursodeoxycholic acid impurities mentioned in EP 7.0, the impurity I, G and A were prepared from chenodeoxycholic acid by oxidation, hydrogenation, and esterification. The purity of the synthesized compounds was higher than 98.0% (HPLC), and their chemical structures were confirmed by MS, 1H NMR, 13C NMR. |
Key words:ursodeoxycholic acid; chenodeoxycholic acid; impurity |
