Grape seed extract is a polyphenol substance extracted from grape seeds. The main active ingredient is a low molecular weight polymer of proanthocyanidins, which is an edible product. It is a powerful antioxidant and a highly effective free radical scavenger. Used in food supplements, health food and cosmetics.Grape seed extract has antioxidant, anti-mutation, anti-cancer, anti-viral, anti-inflammatory, anti-ulcer and cholesterol-lowering effects. It is clinically used to prevent and treat high cholesterol, atherosclerosis, gastric ulcer, etc., as a raw material for food additives, cosmetics, health products and beverages. Grape seed extract is one of the most potent plant-derived antioxidants found to date, and in vivo and in vitro tests have shown that grape seed extract's antioxidant effect is 30-50 times that of vitamin C and vitamin E. The super antioxidant efficiency has the powerful effect of clearing free radicals and improving human immunity.
The medicinal value of grape seed Grape seed has the effect of "invigorating qi and blood, strengthening muscles and bones, relieving urine, treating qi and blood weakness, lung deficiency cough, palpitations, night sweat, rheumatism and pain, gonorrhea, puffiness", etc. Modern research shows that the proanthocyanidin in grape seed extract has the function of anti-oxidation and reducing cholesterol level, which is a natural antioxidant with great potential. It can be used to prevent and treat high cholesterol, atherosclerosis, cataracts, gastric ulcer, intestinal adenocarcinoma, Ehrlich ascites cancer, etc. The main pharmacological effects are as follows:
1. Antioxidant effect: Polyphenols in grape seed extract include proanthocyanidins and phenolic hydroxyl groups of gallic acids, which provide hydrogen atoms and have specific and powerful antioxidant effects. The ability of neutralizing iron ions and oxygen attacking lipids is 15 to 25 times that of VB, and its free radical scavenging effect is stronger than that of antioxidants such as VC.VE.
2, anti-radiation effect: can inhibit the lipid peroxidation caused by radiation.
3, anti-inflammatory effect: the main components are proanthocyanidins, whose antioxidant activity can inhibit the synthesis and release of inflammatory factors such as histamine, 5-hydroxytryptamine, prostaglandin and leukotrienes, inhibit the release of basophils and mast cells, inhibit the activity of histamine decarboxylase, and limit the action of hyaluronidase.
4, the prevention of cataracts: the main component of preventing cataracts is catechin; Grape seed extract can improve the visual acuity of patients with myopic retinal non-inflammatory changes and can improve eye fatigue.
5. Anti-cancer effect: It is cytotoxic to 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: food containing 2.5% grape seed extract can reduce the level of cholesterol ester peroxide in the serum of experimental animals, and can also reduce low-density lipoprotein to combat atherosclerosis. It can improve hemorheology and platelet aggregation.
7. Cholesterol-lowering effect: gallic tannin can reduce plasma total cholesterol, triglyceride, low density cholesterol and very low density cholesterol levels, and increase high density cholesterol levels.
8. Anti-ulcer effect: oligoproanthocyanidins in grape seed extract can protect gastric mucosal damage, and proanthocyanidins have the effect of clearing free radicals on stomach surface and protecting stomach wall.
9, anti-mutation effect: can reduce the incidence of mitochondrial mutation and nuclear mutation.
