pure dihydromyricetin

Dihydromyricetin is a flavonoid compound.

1. Source: It is extracted from plants of the genus Ampelopsis in the family Vitaceae, such as Vine Tea. It is also found in other plants like grapes and citrus, but in relatively lower amounts.

2. Physical properties: It appears as white needle-like crystals with a melting point of 245-246. It has low solubility in water and cold water, but is easily soluble in methanol, ethanol, and acetone. It is slightly soluble inyl acetate and difficult to dissolve in chloroform and petroleum ether.

3. Chemical properties: It can undergo oxidation reactions, dehydrogenation reactions,erification reactions, and can also form complexes with metal ions.

一. Pharmaceutical raw materials

1. Liver protection: It has a significant protective effect on rat liver damaged by carbon tetrachloride, D-galactosamine, and lipopolysaccharide. It can accelerate the decomposition of acetal, a metabolite of ethanol, thereby reducing its damage to liver cells. It can be used to prevent and treat liver diseases such as alcoholic liver and fatty liver

2. Lipid and glucose regulation: It can inhibit fat synthesis and promote fat decomposition, thereby lowering blood lipid levels. It can also significantly inhibit the increase in glucose induced by alloxan, adrenaline, and streptozotocin in mice, while increasing serum insulin levels. It has a certain auxiliary treatment effect diabetes.

3. Anti-thrombosis: It can inhibit platelet aggregation, release, adhesion, and spreading, and can protect endothelial cells from pro-coagulant factors, inhibit tissue factor expression and activation, and reduce fibrin formation. It prevents thrombosis by inhibiting platelet activation and protecting endothelial cells.

4. Anti-tumor: It can inhibit the growth and metastasis of tumor cells and increase the apoptosis rate of tumor cells. It has shown anti-tumor effects in leukemia and nasopharyngeal cancer models.

 5. Antibacterial and anti-inflammatory: It has inhibitory effects on various bacteria such Bacillus subtilis, Staphylococcus aureus, Salmonella, and Escherichia coli, as well as on fungi like Penicium and Aspergillus niger.

二. Food Additives:

6. Anti-oxidant Raw Material: Dihydromyricetin has strong antioxidant and can be used as a natural antioxidant in food to extend the shelf life of food products.

7. Health food: It can be used to develop various health products, such as functional beverages and health capsules. III. Cosmetics field: Due to its antioxidant properties, it can prevent skin cells from being harmed by free, reduce signs of skin aging, and can be used in cosmetics for skin care and whitening effects
