Its main active component is the low-molecular-weight polymer of proanthocyanidins, and it is a food product. It is a powerful antioxidant and an efficient free radical scavenger. It is used in food supplements, health foods and cosmetics, etc.
The medicinal value of grape seeds Grape seeds have the following effects: "tonifying qi and blood, strengthening muscles and bones, promoting urination, treating qi deficiency, lung deficiency cough, palpitations, night sweats, rheumatism pain, gonorrhea, edema", etc. Modern research shows that the proanthocyanidins in grape seed extract have antioxidant and cholesterol-lowering functions, and are a highly potential natural antioxidant that can be used for the prevention and treatment of high cholesterol, atherosclerosis, cataracts, gastric ulcers, intestinal adenocarcinoma, and Ehrlich ascites cancer, etc.
The main pharmacological effects are as follows: 1. Antioxidant effect: The polyphenols in grape seed extract include proanthocyanidins and gallic acid-type phenolic hydroxyl groups, which provide hydrogen atoms and have a specific and powerful antioxidant effect. The ability to neutralize iron ions and oxygen attacking lipids is 15-25 times that of VB, and its free radical scavenging effect is stronger than VC and VE anti-oxidants.
2. Anti-radiation effect: It can inhibit lipid peroxidation caused by radiation.

2. Anti-radiation effect: It can inhibit lipid peroxidation caused by radiation.
3. Anti-inflammatory effect: The main component is proanthocyanidins, and its antioxidant activity can inhibit the synthesis and release of inflammatory factors such as histamine, 5-hydroxytryptamine, prostaglandin, and leukotriene, inhibit the release of granules by basophil cells and mast cells, and also inhibit the activity of histidine decarboxylase and limit the action of hyaluronic acid enzyme.
4. Prevention of cataracts: The main component of prevention of cataracts is catechin; Grape seed extract can improve the vision of patients with non-inflammatory changes in the retina caused by myopia and can improve eye fatigue.
5. Anti-cancer effect: It has cytotoxicity against MCF-7 human breast tumor cells, A-427 human lung cancer cells, and CRL1739 human gastric adenocarcinoma cells, and can prevent the carcinogenic effect of intestinal chemical carcinogens.
6. Anti-atherosclerosis effect: Foods containing 2.5% grape seed extract can reduce the serum cholesterol ester peroxide level in experimental animals and also reduce low-density lipoprotein to counteract atherosclerosis.
It can improve hemorheological indicators and platelet aggregation.
7. Cholesterol-lowering effect: Galloyl ester tannins have the effect of reducing total cholesterol, triglycerides, low-density cholesterol, and very low-density cholesterol levels, and increasing high-density cholesterol levels.
8. Anti-ulcer effect: The low polyphenol proanthocyanidins in grape seed extract can protect the damaged gastric mucosa, and proanthocyanidins have the effect of removing free radicals on the gastric surface and protecting the gastric wall.
9. Anti-mutation effect: It can reduce the incidence of mitochondrial mutations and nuclear mutations.
Grape seed extract is a type of plant extract, with the main component being proanthocyanidins. It is a novel and highly efficient natural antioxidant that cannot be synthesized by the human body and is extracted from grape seeds. It is one of the most effective antioxidants found in plant sources to date. Both in vivo and in vitro experiments have shown that the antioxidant effect of grape seed extract is 50 times stronger than that of vitamin E and 20 times stronger than that of vitamin C. It can effectively remove excess free radicals in the body and has strong anti-aging and immune-enhancing effects. Known main functions include anti-inflammation, anti-histamine, anti-allergy, anti-allergens, antioxidant, anti-fatigue, enhancing physical fitness, improving sub-health conditions, delaying aging, improving irritability, dizziness, fatigue, memory decline symptoms, beautification, promoting blood circulation, etc.
In Europe, Chemicalbook grape seed is hailed as "oral skin cosmetics". Grape seeds are natural sun protectors that can prevent ultraviolet rays from harming the skin. The sun can kill 50% of human skin cells; however, if grape seeds are taken for protection, approximately 85% of skin cells can avoid death. Because the proanthocyanidins (OPC) in grape seeds have a special affinity for collagen and elastic fibers in the skin, they can protect them from damage. Grape seed extract, as the main functional component of Eastern female cosmetics, inhibits tyrosinase activity, eliminates free radicals, reduces melanin deposition and the occurrence of dermatitis, has a constricting effect, tightens the skin, prevents the premature appearance of wrinkles, and has long-term use to make the skin smooth, elastic, and has the effect of beautifying and nourishing the skin.
