| Grape Seed Extract Usage And Synthesis |
| Medicinal value of grape seed |
Grape seed have good effects on benefit “qi” and blood, strengthen the bones, diuresis, treatment of weak “qi” and blood, lung deficiency and cough, night sweats, palpitations, rheumatism, gonorrhea, and edema, etc. Modern research shows that the original anthocyanin of the grape seed extract has effects on anti-oxidation and reducing cholesterol level, making it a potential natural antioxidant. Therefore, it can be used for prevention and treatment of high cholesterol level, atherosclerosis, cataracts, stomach ulcers, intestinal adenocarcinoma, Ehrlich ascites carcinoma, etc. Its main pharmacological effects are as follows: 1. antioxidant: polyphenols of grape seed extract including proanthocyanidins and the phenolic hydroxyl of gallic acids provide specific hydrogen atoms so that they have a strong antioxidant effect. Its ability of neutralizing and attacking the Iron and oxygen in lipids is 15 to 25 times of the VB. Moreover, it has a stronger effect on scavenging free radical than VC.VE and other antioxidants. 2. anti-radiation effects: inhibit the lipid peroxidation caused by radiation. 3. anti-inflammatory effect: its main component is proanthocyanidins, whose anti-oxidation effect can inhibit the synthesis and release of histamine, serotonin, prostaglandins and leukotrienes and other inflammatory cytokines. It also inhibits the basophils and mast cells to release particles, inhibits the activity of histamine decarboxylase, and limiting the role of hyaluronidase. 4. Prevention of cataracts: Catechins is the main component for cataract prevention; grape seed extract can strengthen the myopic retinal and improve the insight of patients in a non-inflammatory form. It can also relieve the eye fatigue. 5. Anti-cancer effect: It has cytotoxicity to the MCF-7 human breast tumor cells, A-427 human lung cancer cells and human gastric adenocarcinoma cells CRL1739. It also prevents the carcinogenesis effect of intestinal chemical carcinogens. 6. Anti-atherosclerotic effect: Food containing 2.5% grape seed extract, can reduce the cholesterol ester peroxide levels in serum of experimental animal, also lower the LDL (low density lipoprotein) level against atherosclerosis. It can further improve blood rheology and platelet aggregation. 7. Cholesterol-lowering effect: Tannin gallic acid ester can reduce the levels of total plasma cholesterol, triglycerides esters, LDL cholesterol and very low density cholesterol, and increase HDL cholesterol levels. 8. Anti-ulcer effect: The oligomeric proanthocyanidins in grape seed extract can protect the gastric mucosa from damage. Proanthocyanidins can also scavenge the free radical on stomach surface and protect the gastric wall. 9. Anti-mutagenic effect: can reduce the incidence of mitochondria mutation and nuclear mutation. The above information is edited by the Chemicalbook of Dai Xiongfeng. |
| Plant Extract |
Grape seed extract is a plant extract, with the main ingredient, proanthocyanidins (cannot synthesized in vivo of human body), which is a novel natural anti-oxidant extracted from grape seeds. It is currently one of the most efficient plant-derived anti-oxidant. Both in vivo and in vitro tests showed that the antioxidant effect of grape seed extract is 50 times of vitamin E, 20 times stronger than vitamin C. It can effectively remove excess free radicals in the human body, thus having a superior anti-aging effect and can enhance immunity ability. The main known effects include anti-inflammatory, anti-histamine, anti-allergic, anti-allergen, anti-oxidation, anti-fatigue and improving physical fitness, improving the sub-health state and suppressing aging, treating irritability, alleviating dizziness, fatigue and hypomnesia, beauty, promoting blood circulation and so on. In Europe, grape seed is known as "oral skin cosmetics." Grape seed is a natural sun shelter, which can keep the skin away from ultraviolet rays. The sun can kill 50% of human skin cells; but if be protected by grape seed, about 85% of the skin cells can finally survive. Owing to the special affinity of proanthocyanidins (OPC) in grape seed to the skin collagen and elastic fibers, it is possible to protect them from damage. Grape seed extract is a main functional ingredient of cosmetics for oriental women. By inhibiting the activity of tyrosinase, it scavenges free radicals and reduces melanin deposition and skin inflammation occurrence. Thus it has the effect of convergence, tightening the skin and preventing skin wrinkle from appearing early. Long-term use can make the skin smooth and elastic with a effect of beauty. |
