chenodeoxycholic acid：synthesis method and Chemical property

This product is extracted from the bile of pigs, chickens, ducks, geese, white or light yellow crystalline powder, bitter taste,.Mp141-142 C, soluble in ethanol, chloroform and acetic acid, almost insoluble in water.

This product can make the cholesterol synthesis and secretion is reduced, total cholesterol in bile excretion decreased, thereby improving the dissolving capacity of cholesterol in bile, promote has stone cholesterol dissociation to dissolve stone effect. A high concentration in the gallbladder after oral administration of the goods and repeatedly enterohepatic circulation. This product in the gut easily decomposing bacteria, produce liver toxicity of the metabolites.

Use
