is white crystal or crystalline powder; odorless, slightly bitter; color gradually darkens when exposed to light; after dissolving in water, part of the lactone turns into glucuronic acid, reaching a state of equilibrium, showing an acidic reaction. This product is easily soluble in water, slightly soluble in methanol, and slightly soluble in ethanol. The melting point is {{0}} degree (decomposition), and the specific rotation is +18.0 degree -+20.0 degree (0.1g/ml). After this product enters the body, under the catalysis of the enzyme, the lactone ring is opened and turned into glucuronic acid to play a role. Glucuronic acid is one of the important detoxifying substances in the body. It can combine with poisons and drugs containing carboxyl groups in the liver or intestines to form non-toxic or low-toxic glucuronic acid conjugates and be excreted in the urine; it can also reduce the activity of liver amylase, prevent glycogenolysis, increase liver glycogen, and reduce fat storage, thereby protecting the liver and detoxifying.

is used for the following:Glucuronolactone powder participates in liver detoxification, combines with metabolites, drugs and poisons containing phenolic, hydroxyl and amino groups in the liver or intestine to form non-toxic glucuronic acid conjugates, which are excreted from urine through the kidneys. Therefore, it has the function of protecting the liver and detoxification. It can also reduce the activity of liver amylase, prevent glycogenolysis, increase liver glycogen and reduce fat storage. Clinically, glucuronolactone is mainly used to treat acute and chronic hepatitis, early liver cirrhosis, food and drug poisoning, etc. Since this product is an important component of connective tissue and collagen, it is also used to treat arthritis and collagen diseases.
Step (1): Hydrolysis: Pump the carboxyl starch liquid into the hydrolysis tank, steam heat it to 100 degree , and yellow smoke and water vapor will come out. Then seal it, increase the internal pressure to 245.25kPa, the temperature is 140-142 degree , hydrolyze for 2h, and get the hydrolyzate, that is, the glucuronic acid solution. Hydroxyl starch liquid [245kPa]→[140-142 degree , 2h] Hydrolyzate lactone is decolorized by the exchange resin, and the hydrolyzate is concentrated under reduced pressure to 34-36 degree Be.
Step (2): Add glacial acetic acid 1.8 times the amount of starch feed to the concentrate, esterify at room temperature for 16-24h, cool to 0-5 degree for crystallization, filter, and get the crude glucuronic acid lactone. Place the crude product and distilled water in a refining tank, heat, and stir continuously to make them completely dissolved, add activated carbon for decolorization, add ethanol, stir evenly, filter by suction, cool the filtrate to 0-5 degree , leave for 16 hours, filter, wash the filter cake once with anhydrous ethanol, spin dry, and dry below 80 degree to obtain the fine glucurone lactone.
