Pure Resveratrol Powder

  Product Detail  

Pure Resveratrol Powder is an antitoxin secreted by plants when they encounter adversity or pathogen attack. The synthesis of resveratrol increases sharply under ultraviolet radiation, mechanical damage and fungal infection, so it is called phytoalexin. In vitro experiments and animal experiments have shown that resveratrol has antioxidant, anti-inflammatory, anti-cancer and cardiovascular protection effects. Human foods such as grapes and knotweed have higher levels.

The Pure Resveratrol Powder is white to light yellow powder, odorless, with a melting point of 253-255°C and a sublimation temperature of 261°C. It can appear red in an alkaline solution such as ammonia water and can produce a color reaction with ferric trichloride-potassium ferricyanide. Resveratrol can be identified by using this property. Resveratrol is an antitoxin secreted by plants in adversity or when they encounter pathogens. The synthesis of resveratrol increases sharply under ultraviolet radiation, mechanical damage and fungal infection, so it is called plant antibiotics.

Natural resveratrol has two structures, cis and trans. It mainly exists in trans conformation in nature. The two structures can combine with glucose respectively to form cis and trans-resveratrol glycosides. The cis and trans-resveratrol glycosides can release resveratrol under the action of glycosidase in the intestine. Trans-resveratrol can be converted to the cis isomer under ultraviolet light irradiation.

▲Metabolism, absorption and distribution of resveratrol in vivo:

Resveratrol has relatively low bioavailability in the body, and studies have shown that the bioavailability of resveratrol metabolites in the small intestine and liver is about 1%. Metabolism is rapid in animals, and the peak can be reached in plasma within 5 minutes, and it is mainly metabolized in the form of resveratrol sulfated and glucuronidated products. Resveratrol is distributed into different tissues of mammals in a bound form, and resveratrol is more absorbed and distributed in organs with rich blood perfusions, such as the liver, kidney, heart and brain.

Resveratrol is easily absorbed when taken orally and excreted through urine and feces after metabolism. In vitro experiments and animal experiments have shown that resveratrol has anti-oxidation, anti-inflammatory, anti-cancer, cardiovascular protection, whitening, moisturizing and other effects. :

◎Natural antioxidant, has a strong effect of scavenging free radicals and anti-lipid peroxidation. The antioxidant effect is stronger than traditional antioxidants such as vitamin C, butylated hydroxytoluene, and tocopherol. By scavenging or inhibiting free radicals and their metabolites, the scavenging of free radicals reduces the H2O2 content in the skin, improves the activity of ATPase to play an antioxidant role, and delays skin aging; and increases the antioxidant activity of low-density lipoprotein Inhibits aging caused by lipid peroxidation.

◎Protect the cardiovascular system.

 Avoid myocardial ischemia-reperfusion myocardial injury, anti-atherosclerosis and thrombosis, anti-inflammation, anti-oxidative damage, and vasodilation.

◎Anti-tumor activity. Block cell cycle and promote tumor cell apoptosis

◎Regulate the immune system

◎Protect the liver

◎Suppress oil production. 

Resveratrol has good adhesion to the skin and can shrink large pores, tighten loose skin to reduce wrinkles, and prevent the skin from secreting too much oil.

◎Whitening. 

Resveratrol is more helpful to inhibit the activity of "tyrosinase" (the higher the activity of tyrosinase, the easier the formation of melanin), and reduce the formation of a large amount of melanin in the human body due to factors such as ultraviolet rays, photosensitivity, and photosensitive food, and the appearance of melanin. Spots, skin darkening and other conditions, to achieve the effect of whitening, and blemishes.

◎Treatment of acne.

 Resveratrol also has anti-inflammatory and bactericidal effects and is suitable for treating skin acne. It relieves acne by inhibiting the key target of acne-causing rapamycin target protein C1 and has a good anti-acne effect in vitro. Resveratrol is safer than the other most effective over-the-counter acne treatment, benzoyl peroxide, which has side effects and requires long-term use to be effective.

◎Anti-inflammatory. 

Resveratrol has the effect of anti-inflammatory response, can inhibit the activity of COX-2 (reoxidase), an important medium of the human inflammatory response, reduce the chances of viruses, bacteria, ultraviolet rays and other factors to induce the activity of COX-2, and improve skin redness and swelling, heat pain and other inflammation, sensitive reaction.

◎Moisturizing. 

Resveratrol can inhibit the penetration of cell moisture and reduce the loss of skin moisture; and its water absorption capacity is first-rate, helping the skin maintain a moist and plump state.
