Resveratrol is a natural antioxidant. It can reduce blood viscosity, inhibit platelet aggregation and vasodilation, keep the blood flowing and prevent the occurrence and development of cancer. It has the function to prevent and treat atherosclerosis, coronary heart disease, ischemic heart disease and high blood cholesterol. It has an effect on suppressing tumor. Resveratrol also has estrogen-like effects that can be used to treat breast cancer and other diseases. It can retard aging and prevent cancer. Red grape skins, red wine and grape juice have high concentrations of resveratrol. Studies have shown that the integrity of the chromosomes will be destroyed as the human aging. But resveratrol can activate proteins that can repair chromosome, thus delaying aging. Resveratrol is a polyphenolic phytoalexin. It is also classified as a stilbenoid, a derivate of stilbene, and is produced in plants with the help of the enzyme stilbene synthase. The levels of resveratrol found in food varies greatly. Red wine contains between 0. 2 and 5. 8 mg/L depending on the grape variety, while white wine has much less. The reason for this difference is that red wine is fermented with grape skins, allowing the wine to absorb the resveratrol, whereas white wine is fermented after the skin has been removed. Resveratrol is a very effective anti-oxidant with 95% efficiency in preventing lipid peroxidation as compared with 37% for Vitamin C or 65% for Vitamin E. It has very strong peroxyl radical scavenging abilities, more than gallic and ellagic acids and epicatechins. Resveratrol has been shown to protect against UVB mediated skin damage in mice by boosting anti-oxidant defenses, and it has been shown to help alleviate skin wounds. Resveratrol is effective against photoaging due, in part, to its anti-oxidant properties, and is recommended for use in pre- or post-sun exposure products. Resveratrol can pass through the stratum corneum to be found in the dermis and epidermis. It has been shown to preserve dermal collagen, and may be effective in enhancing glycosaminoglycans, which enhance tissue hydration. It has been shown to stimulate skin’s cellular renewal, and help increase skin's thickness. And it has been shown to inhibit tyrosinase, which indicates its use for reducing hyperpigmentation.
Resveratrol can prevent the oxidation of low density lipoprotein, and has the potential effect on preventing cardiovascular disease, cancer, antivirus and immune regulation. Its main role is antioxidant properties. Cardiovascular drugs, it can reduce hematic fat and prevent heart disease. It also has the effect on AIDS. Antioxidants and the activity in anti-inflammatory, antithrombotic, anti-cancer, anti-cancer, anti hyperlipidemia and antibacterial. Anti-aging, regulating blood lipid, cardiovascular protection, anti-hepatitis. Resveratrol is a phytoalexin produced naturally by several plants with anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects.
