The main pharmacological activity

1, anti-tumor effect

Resveratrol is a natural cancer chemopreventive agent, has good anti-cancer activity, and can have inhibitory effects on cancer cells. The anti-cancer mechanisms include: ① block cell cycle, inhibit the proliferation of cancer cells ② promote apoptosis of cancer cells ③ inhibit the metastasis of cancer cells.

2, the role of the cardiovascular system

The major active protective factor of resveratrol in wine can exert its cardiovascular protective effects by reducing myocardial ischemia-reperfusion injury, inhibiting the formation of atherosclerosis and thrombus, anti-inflammation, anti-oxidation and vasodilation. Resveratrol at physiological concentrations (0.1 μmol / L) can vasodilate and therefore function to lower blood pressure and reduce the risk of cardiovascular disease.

3, anti-oxidation, anti-free radical effect

Resveratrol is a natural antioxidant existing in plants. Its mechanism of anti-oxidation is mainly to eliminate or inhibit free radical generation, inhibit lipid peroxidation and regulate antioxidant activity.

4, antibacterial effect

Resveratrol has a strong antibacterial effect on staphylococci.

5, anti-aging effect

Resveratrol activates acetylases and increases the lifespan of yeast. Studies have shown that resveratrol can prolong the life span of yeasts, nematodes, fruit flies and lower fishes.

6, the regulation of the immune system

Different doses of resveratrol could significantly increase the phagocytic rate of macrophages, the hemolytic value of serum, the number of antibody-forming cells, the rate of lymphocyte transformation and the degree of swelling of mouse ears (that is, normal mice Type IV hypersensitivity). Resveratrol on immune function in normal mice had no significant effect, but can inhibit type IV hypersensitivity.

7, other biological functions

Resveratrol also has the role of immune regulation, anti-virus, anti-allergy, liver protection and so on. In addition, resveratrol can be used as an additive to drugs, alcohol or cosmetics, as a new beauty and health products to delay aging, maintain skin moisture, get rid of sores, melasma and so on.
