[What is Vine tea Extract?]
Vine tea, also be called as dragon-boat tea, dragon-whisker tea, young stem and leaf from Ampelopsis grossedentat , a plant of (Ampelopsis grossedentata)(Hand-Mazz)W.T.wang, growing in 1300-1950m hillside shrub or valley woodland , always be consider as legendary healthy tea. Researches show than vine tea can relieve inflammatory, mixture cough and antitussives, it also has strong inhibitory effect to common bacteria can be found in food.

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. Ampelopsis injection is expected to be a new treatment for leukemia and nasopharyngeal cancer.

[Biological Activity of Vine Tea Extract Dihydromyricetin]

Dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) is a natural antioxidant with good prospects. The physicochemical properties of dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) were analyzed by ultraviolet–visible spectrometry, infrared spectrometry, scanning electron microscopy, differential scanning calorimetry, X-ray diffractometry. The result showed that dihydromyricetin (Ampelopsin (flavanol); Ampeloptin) and Lecithin in the complex were combined by non-covalent bond, did not form a new compound and the solubility of dihydromyricetin in n-octanol was significantly enhanced. It was found that the dihydromyricetin–lecithin complex was an effective scavenger of DPPH radicals with an IC50 of 22.60 μg/mL. In the Rancimat antioxidant test using lard oil as substrate, the performance of the complex with protection factor of 6.67 was superior to that of butylated hydroxytoluene with protection factor of 5.54.
