Properties and stability
1. This product is a synthetic derivative of cholic acid, which has choleretic effects and promotes bile secretion. It has a rapid onset of action, maximum effect is achieved within 20 to 30 minutes of intravenous injection, and the maintenance time is short.
Storage method
This product should be stored in a sealed, cool, dry place away from light.
Synthesis method
Heat and boil the bile paste containing taurocholic acid and glycocholic acid with sodium hydroxide solution. After hydrolysis for 16 hours, acidify to pH 3. Filter out the gray-brown lumps, boil them in hot water for 10 minutes, cool, filter, and wash with water. , drained, and dried at 60-70°C to obtain cholic acid. Put cholic acid into acetic acid and sodium acetate solution, add chlorine gas at 10-20°C until all the white solids precipitate, wash with a large amount of distilled water, filter and dry to obtain crude dehydrocholic acid, which is refined with ethanol to obtain the finished product.
Purpose
1. Used for biochemical research. This product is a bile acid substance and is used for gallbladder and bile duct dysfunction; condensation syndrome after cholecystectomy; chronic cholecystitis; cholelithiasis and chronic hepatitis.
2.Choletrophin.
