| titleOfInvention | The separation purifying technique of high-purity natural ursodesoxycholic acid can be prepared |
| abstract | The invention belongs to technical field of pharmaceutical biotechnology, and the separation purifying technique of high-purity natural ursodesoxycholic acid can be prepared more particularly to one kind.High-purity natural ursodesoxycholic acid isolates and purifies gained by bear gall powder prepared by drain-out bear gall, and high-efficient liquid phase color spectral purity is not less than 98%.Preparation method is: isolating and purifying the Tauro ursodesoxy cholic acid that preparation purity is not less than 90% using cation exchange medium first; then Tauro ursodesoxy cholic acid is thoroughly hydrolyzed to ursodesoxycholic acid and taurine under alkaline condition, silica gel adsorption chromatography technology is reapplied and isolates and purifies the ursodesoxycholic acid that preparation purity is not less than 98%.Natural ursodesoxycholic acid produced by the present invention has treatment primary biliary cirrhosis and primary sclerotic cholangitis effect. |
