Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
Other Name: Natural Resveratrol INCI Name: RESVERATROL Molecular Formula: C14H12O3 Molecular Weight: 228.24 Appearance: Off-white powder Purity: 98% CAS NO.: 501-36-0 EINECS No.: 610-504-8 Standard: CP,USP Application: cosmetics and skin care products Supplier: ZHENYIBIO Resveratrol has a good antioxidant function, especially it can resist the activity of free genes in the body. It has the ability to repair and regenerate the cells of aging skin, thus making your skin more elastic and whitening from the inside to the outside. In cosmetics, resveratrol mainly plays an anti-aging effect. Resveratrol is a natural antioxidant that eliminates or inhibits the generation of free radicals, inhibits lipid peroxidation, and regulates the activity of antioxidant-related enzymes. And other mechanisms play an anti-oxidant effect. Resveratrol can repair damaged cells, rapidly regenerate cells, revive necrotic tissue cells, vigorously grow atrophic nerves, scavenge free radicals, discharge heavy metal toxins, restart the body's powerful self-repair ability, and improve the vitality and youth index. Make the skin whiter, moisturized and elastic. Main Function: 1. Resveratrol has strong antioxidant and anti-free radical effects.The aging of human skin is mainly caused by oxidative damage caused by the influence of external substances.Therefore, the antioxidant activity of resveratrol plays a particularly important role in skin aging. 2. Dry skin are also skin problems that plague many people.If resveratrol is used as an additive in some cosmetics and skin care products, as a star beauty and health care product,it can have a significant water-locking effect on the skin and keep the skin moist and elastic. 3. Resveratrol has a good removal effect on skin freckles, chloasma, acne and acne.Resveratrol itself is easily absorbed by human skin cells, so when used as a skin care product,it has a very obvious improvement effect on the skin. 4. Resveratrol also has a certain mechanism of action in protecting the skin from radiation. Resveratrol can effectively protect the skin from the damage of these radiation sources under the damage of external factors such as computers, mobile phones and ultraviolet rays.

Molecular formula: C22H18O11 Molecular weight: 458.38 CAS No.: 989-51-5 Product Spec.: EGCG 90% Physiological Functions Modern research and scientific data demonstrates that the beneficial effects of green tea are largely due to its main catechin, Epigallocatechin Gallate (EGCG). EGCG makes up about 30%-50% of the total catechin content and has an antioxidant activity about 25-100 times more potent than Vitamin C and E. Recent research has also indicated that there may be positive effects of EGCG in the field of disease risk reduction regarding cancer and cardiovascular disease. Further research has revealed additional findings where green tea, green tea extract and its constituents can also contribute: Product characteristic *A very pure and refined off-white compound with strong healthy function, which can be added to a broad range of dietary supplements, food products and beverages without a major impact on their color and taste. * Much cheaper than other companies price with the same quality. Inner Packing ---- Pack in plastic & aluminum pouches of 10kg/pouch. Outer Packing ----Paper drums of 20kg/drum (2 pouches in a drum).
Tyrosine is an important nutritionally essential amino acid that plays an important role in the metabolism, growth and development of humans and animals, and is widely used in food, feed, medicine and chemical industries. It is often used as a nutritional supplement for patients with phenylketonuria, and as a raw material for the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as danshensu, resveratrol, and hydroxytyrosol are found in organisms, L-tyrosine is increasingly developing in the direction of platform compounds. Tyrosine is one of the 22 kinds of amino acids used by cells to synthesize proteins. It can be used to synthesize proteins in cells. Its codons are UAC and UAU. It is a non-essential amino acid that contains polar side groups and can be synthesized by the human body. The word "tyrosine" comes from the Greek tyros, meaning cheese. It was first discovered in the casein of cheese by the German chemist Justus von Liebig in the early 19th century. When it is used as a functional group or a side group, it is called tyrosyl. Function In addition to being a proteinogenic amino acid, tyrosine has a special role in signal transduction in proteins by means of a phenolic function, which functions as a receptor for phosphate groups transferred by protein kinases (so-called tyrosine kinase receptors). organ, while phosphorylation of hydroxyl groups alters the activity of the target protein. Tyrosine also plays an important role in photosynthesis. In chloroplasts (photosystem II), it is used as an electron donor in the reduction reaction of oxidized chlorophyll, allowing it to deprotonate the phenolic OH-group, and finally in Photosystem II is reduced by four core manganese clusters. Dietary Sources Tyrosine can be synthesized from phenylalanine in the body and can be found in many high-protein foods such as chicken, turkey, fish, milk, yogurt, cheese, cottage cheese, peanuts, almonds, pumpkin seeds, sesame, soybeans, lima beans , found in avocados and bananas.
