Products Description
Ursodeoxycholic Acid is a white powder; odorless and bitter. It is easily soluble in ethanol, insoluble in chloroform; easily soluble in glacial acetic acid, and soluble in sodium hydroxide test solution. The melting point is 200-204℃.
Ursodiol is a unique component in bear bile. It is an isomer of chenodeoxycholic acid, but it is less toxic than chenodeoxycholic acid and needs to be used in smaller amounts.

Uses
Ursodeoxycholic Acid is mainly used to treat diseases related to bile acid metabolism, such as hepatitis, cholestasis, gallstones, etc. It can protect the function of the liver and bile duct by reducing liver cholesterol synthesis, increasing bile excretion and inhibiting the synthesis of liver toxins.
Inspection Process
Appearance and properties inspection
The sample should be white powder or crystalline powder.
Melting point determination
Use melting point instrument to determine, the melting point standard range is between 203℃-204℃.
Specific rotation detection
Use polarimeter to detect, the specific rotation is about + 44.5°(c, 2.0 in EtOH) ,+58°(c, 2.0 in EtOH).
Purity detection
Use high performance liquid chromatography or gas chromatography, dissolve the sample in a suitable solvent and inject it into the instrument, compare with the standard, and calculate the purity. Purity can also be evaluated by measuring its drying loss, ignition residue and other indicators, such as drying loss should be ≤1.0%, ignition residue should be ≤0.2%.
Solubility test
Take an appropriate amount of sample, add ethanol, glacial acetic acid, chloroform, water and other solvents, observe its dissolution, it should be easily soluble in ethanol and glacial acetic acid, slightly soluble in chloroform, and almost insoluble in water.
Acidity coefficient test
The acidity coefficient can be determined by potentiometric titration, etc., and its pKa value is 5.04±0.04.
Stability test
Put the sample under different environmental conditions, such as high temperature, light, etc., observe the changes in its appearance, properties, content and other indicators to evaluate its stability.
