3. Function

Dihydromyricetin is an extract of Vitis vine tea. It is the main active ingredient flavonoids in vine tea. This type of substance has many unique effects such as scavenging free radicals, anti-oxidation, anti-thrombosis, anti-tumor, anti-inflammatory, etc.; Dihydromyricetin is a special kind of flavonoids, which is effective in detoxifying alcoholism, preventing alcoholic liver, fatty liver, inhibiting liver cell deterioration, reducing the incidence of liver cancer, anti-hypertension, and inhibiting platelet aggregation in vitro and thrombosis in vivo. It has special effects in forming and lowering blood lipid and blood sugar levels, improving SOD activity and protecting the liver.
Antibacterial effect: Pharmacological experiments have shown that dihydromyricetin is effective against Bacillus subtilis, Staphylococcus aureus, Salmonella, Escherichia coli, Aerobacter, Saccharomyces cerevisiae, Rhodotorula glutinosa, Penicillium, Aspergillus niger, Aspergillus flavus, and Phyllanthus Both mold and Rhizopus have antibacterial effects, especially for Gram-positive and Gram-negative cocci or bacilli.
Regulating effect on blood sugar and blood lipids: The pharmacological experiment of mouse gavage shows that dihydromyricetin can obviously inhibit the increase of blood sugar in mice induced by alloxan, epinephrine, streptozotocin, etc., and at the same time increase the level of serum insulin. The infiltration of lymphocytes in pancreatic tissue was significantly reduced, the inflammatory response was significantly reduced, and the number of pancreatic islets was significantly increased. Dihydromyricetin has a lowering effect on serum triglyceride (TG) content in rats with streptozotocin-induced hyperglycemia, but has no significant effect on serum total cholesterol (TC) and high-density lipoprotein cholesterol (HDL2C) content.

Liver protection: Dihydromyricetin has a significant protective effect on the toxic injury of carbon tetrachloride in cultured rat hepatocytes and D2 galactosamine and lipopolysaccharide-induced liver injury in mice. Dihydromyricetin can protect the liver, accelerate the rapid decomposition of ethanol metabolite acetaldehyde, into a non-toxic substance, and reduce its damage to liver cells. In addition, dihydromyricetin can improve the increase in serum lactate dehydrogenase activity caused by liver cell injury, inhibit the formation of hepatic M cell collagen fibers, thereby protecting the liver and greatly reducing the damage of ethanol to the liver. The normal state of the liver can be quickly restored. The Microherb test proved that dihydromyricetin can protect the liver, accelerate the rapid decomposition of ethanol metabolite acetaldehyde, turn it into a non-toxic substance, and reduce the damage to liver cells. Dihydromyricetin takes effect quickly and lasts for a long time. It is a good product for protecting the liver, protecting the liver, and sobering up alcohol.

Antioxidant effect: Dihydromyricetin with a purity of 98% can significantly inhibit the production of malondialdehyde (MDA) in rat myocardial, liver and brain tissue homogenates, and inhibit the production of MDA as the concentration of dihydromyricetin increases The effect is increased, and the 99% content of dihydromyricetin has the scavenging rate of diphenyltrinitrophenylhydrazine (DPPH) free radicals in the test system. Dihydromyricetin can obviously inhibit the formation of MDA in oils. With the increase of the purity of dihydromyricetin (60%～90%), the antioxidant effect is enhanced; it has strong antioxidant effect on animal oil and vegetable oil.

Anti-tumor effect: In recent years, anti-tumor pharmacodynamics studies have found that one of its active ingredients, the small molecule compound of cephalosporin has a relatively strong anti-cancer effect. In vitro anti-tumor effect studies have found that the compound can improve tumor treatment effects and improve patient vital signs by inhibiting tumor blood vessel growth, regulating and enhancing cellular immune function. It has been used in tumor model test studies such as leukemia and nasopharyngeal carcinoma. Shows obvious anti-tumor effect.
