The pharmacological experiments showed that Dihydromyricetin had a bacteriostasis effect on Bacillus subtilis, Staphylococcus aureus, Salmonella, Escherichia coli, bacilli, Saccharomyces cerevisiae, myxomyces, Penicillium, Aspergillus niger, Aspergillus flavus, Mucor, and Rhizopus, especially gram-positive, gram-negative cocci.

Dihydromyricetin could obviously inhibit the increase of blood glucose induced by four oxalic, adrenalin, and streptozotocin. At the same time, the level of serum insulin was increased. The infiltration of lymphocytes in the pancreas tissue was significantly reduced, the inflammatory response was obviously reduced, and the number of islets increased significantly.

Dihydromyricetin can protect the liver, accelerate the decomposition of acetaldehyde and become a non-toxic substance, and reduce the damage to liver cells. In addition, Dihydromyricetin can improve the activity of serum lactate dehydrogenase and inhibit the formation of collagen fibers in liver M cells, thus playing a role in protecting the liver, greatly reducing the damage of ethanol to the liver, so that the normal state of the liver is rapidly recovered. The Microherb test showed that Dihydromyricetin could protect the liver, accelerate the rapid decomposition of acetaldehyde and become a nontoxic substance and reduce the damage to liver cells. Dihydromyricetin is effective. It is a good product to protect the liver and liver, relieve alcoholism, and sober up.

Dihydromyricetin, with a purity of 98%, can obviously inhibit the formation of malondialdehyde (MDA) in the myocardium, liver, and brain homogenate, and increase the effectiveness of the inhibition of MDA formation with the increase of the concentration of Dihydromyricetin, and the clearance rate of the two benzene three nitrophenyl hydrazine (DPPH) free radical in the test system. Dihydromyricetin can obviously inhibit the formation of MDA in oil and increase the antioxidant effect and has a strong antioxidant effect on animal oil and vegetable oil.

In recent years, anti-tumor pharmacodynamic studies have found that one of the active components is Ampelopsis, a small molecule compound that has a strong anti-cancer effect. The antitumor effect in vitro shows that the compound can improve the therapeutic effect of tumors and improve the patient’s life-body disease by inhibiting the growth of tumor vessels and regulating the immune function of the cell. The tumor suppressor effect is obvious in the model test of leukemia and nasopharyngeal carcinoma.
