Some of flavonoids, for example Ampelopsin and Dihydromyricetin, are main active ingredients in vine tea,

which have almost same MIC and MBC comparing with berberine, and have high Free radical scavenging activity varies between 73.3~91.5%. It can also reduce oxidative damage in the body, anti-aging, reduce the deformation and tissue necrosis of animal liver.

Dihydromyricetin also have ability on lifting alcohol poisoning, prevent for AFL, inhibit the deterioration of liver cells, decrease the incidence of liver cancer. In these case Dihydromyricetin is consider as a good product for enhance activity of SOD, protecting liver and removing inebriation.

Dihydromyricetin now entered clinical trials as a class of new drugs when researcher of Dihydromyricetin achieved a major breakthrough in field of anti-leukemia and medicine of Nasopharyngeal cancer.

Function of Vine Tea Extract,Dihydromyricetin

1.Anti-inflammation: The vine tea extract can effectively restrain the mouse pinna swelling caused

by xylene. It can also restrain the writhing response in the mouse caused by acetic acid.

2. Clearing the free radical in body and antioxidation: The vine tea extract can effectively

level down the lipid peroxidation. It can prevent the oxidative damage of antioxidase in

body caused by the free radical. Then it can improve the oxidation resistance of the

human body;

3.Antibiotic Action: The vine tea extract has the strong inhibitory action of staphylococcus

aureus and Bacillus subtilis. It also has inhibitory action of Aspergillus flavus, Aspergillus

niger, penicillium and Alternaria. Dihydromyricetin has the inhibitory action of Staphylococcus
