As a major flavonoid in the leaves of Ampelopsis grossedentata,Studies showed that dihydromyricelin has multiple pharmacological effects, such as antitumor, anti-inflammation, anti-oxidation, blood lipid regulation, anti-temulence and liver protection, antidiabetics, and anti-pathogeny microorganism.

What is Vine tea?
Vine tea is one of a rare plant. Botanical name is ampelopsis grossedentata, it is one kind of typical tea plant, "Chinese Herbal Medicine Collection" wrote that the vine tea (Teng Cha )has a glycol flavor, the nature is cool; It can alleviate fevers, dis-intoxicate, cure rheumatism, strengthen physique, diuresize, and many other functions. The vine tea (Teng Cha) contains rich flvones, amino acids, vitamins; Proteins and essential trace element, in which the content of total flavones, and Dihydromyricetin elementis are especially high.
Function:
1)
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;
2)
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 aureus, Staphylococcus aureus(S. aureus) and Pseudomonas aeruginosa.
3)
Protecting the Liver: Dihydromyricetin has the strong inhibitory action of the rise of ALT and AST in the blood Serum. It can low the total bilirubin in the blood serum. So it has the strong action oflowing the aminotransferase and jaundice. The vine tea extract can restrain the liver fibrosis in the rat.
4)
Reducing the levels of blood sugar and blood fat: Dihydromyricetin can reduce the blood fat levels in the mouse. It can decrease the damage to liver cells caused by the high blood fat levels and improve the antioxidation ability. At the same time, it can low the levels of high blood sugar.
- 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.
Application: pharmaceutical field
