Two arbutus pigment is one of the main active ingredients of rattan tea, has a variety of biological functions, with free radicals antioxidant antihypertensive antithrombotic antitumor anti-inflammatory and other strange effect Dihydrogen Yang mei, as a special kind of flavonoid compounds, besides has the general characteristic of flavonoids, also has alcohol poisoning Prevention of alcohol liver fatty liver Inhibit the deterioration of liver cells to reduce the incidence of liver cancer and other effects, is to protect the liver to protect the liver, hangover hangover good product antibacterial effect: pharmacological experiments show that dihydromyricetin on bacillus subtilis staphylococcus aureus salmonella Escherichia coli aerobacterium beer yeast red yeast penicillium Niger Aspergillus aflatus Both Mucor and rhizopus had bacteriostatic effects, especially on gram-positive gram-negative cocci or bacillus

1, antibacterial action, pharmacological experiments showed that the hydrogen arbutus pigment of hay bacillus coli, staphylococcus aureus, salmonella and e. coli, gas bacillus, beer yeast, sticky red yeast, penicillium and aspergillus Niger, aspergillus flavus, mucor and rhizopus has bacteriostatic action, especially for gram positive and gram negative coccus and bacillus.
2, on blood sugar, blood lipid regulation: mice stomach pharmacological experiments show that the hydrogen arbutus pigment can obviously inhibit the alloxan, adren'aline and urea chain drug induced mice blood glucose, elevated serum in'sulin levels at the same time, lymphocyte infiltration in the pancreas significantly reduce decreased significantly, inflammation response, islet number increased significantly. Dihydromyricetin can reduce the content of triglyceride (TG) in serum of streptozotocin induced hyperglycemia rats, but has no significant effect on the content of total cholesterol (TC) and high density lipoprotein cholesterol (HDL2C) in serum.
3, liver protection: Dihydromyricetin has a significant protective effect on cultured rat liver cells from car'bon tetrachloride toxic injury, d2-galactosamine and lipopolysaccharide induced liver injury in mice. Dihydromyricetin can protect the liver, accelerate the rapid decomposition of ethanol metabolite ace'taldehyde into non-toxic substance, and reduce its damage to liver cells. In addition, dihydromyricetin can improve the increase of serum lactate dehydrogenase activity caused by liver cell injury and inhibit the formation of hepatic M cell collagen fiber, thereby protecting the liver and protecting the liver, greatly reducing the damage caused by ethanol to the liver and rapidly recovering the normal state of the liver. Microherb test proved that dihydromyricetin can protect the liver, accelerate the rapid decomposition of ethanol metabolite ace'taldehyde into non-toxic substance, and reduce the damage to liver cells. Dihydromyricetin has a quick and lasting effect, which is a good product for protecting liver, curing alcohol and sobriety.
4. Antioxidant effect: 98% dihydromyricetin can significantly inhibit the generation of malondialdehyde (MDA) in rat heart, liver and brain tissue homogenates, and the inhibition of MDA generation increases with the increase of the concentration of dihydromyricetin. The clearance rate of diphenyltrinitrophenylhydrazine (DPPH) free radical in the test system of 99% dihydromyricetin. Dihydromyricetin can significantly inhibit the generation of MDA in oil, and its antioxidant activity is enhanced with the increase of the purity of dihydromyricetin (60% ~ 90%). It has strong antioxidant effect on animal oil and vegetable oil.
5. Anti-tumor effect: in recent years, anti-tumor pharmacodynamics studies have found that one of its active components, small molecule compounds of ophitin, has relatively strong anti-tumor effect. It was found that the compound could improve the therapeutic effect of tumor and improve the patient's biological symptoms by inhibiting the growth of tumor blood vessels, regulating and enhancing cellular immune function, etc. It has been shown to have obvious tumor suppressive effect in leukemia and nasopharyngeal cancer model experiments.
