2. Active ingredients of grape seed extract

Grape seed extract polyphenols (GSP) are divided into monomeric phenols and polymerized polyphenols. The monomeric phenols are mainly gallic acid, catechins, epicatechins and catechins, and the gallic acid esters of epicatechins. . Polymerized polyphenols are mainly procyanidins with different polymerization degrees formed by the polymerization of several flavanones.

According to different degrees of polymerization, proanthocyanidins are divided into oligomeric procyanidins (OPCs) and high-polymer proanthocyanidins (PPCs): grape seed proanthocyanidins dimers, trimers, tetramers, pentamers and hexamers to decamers. Among them, dimers to tetramers are oligomers. The grape seed extract oligomeric proanthocyanidins have better biological activity, so the content of OPCs in GSE determines the quality of the product.

This is mainly because it contains an anti-cancer trace element (resveratrol), which can prevent healthy cell cancer. Change and prevent the spread of cancer cells. This resveratrol, which is rich in grape skins and grape seeds, is the most important ingredient in grapes and an excellent food for antioxidants. Therefore, it is scientific to eat grapes without spitting out grape skins.

8. Eating grape skins and grape seeds together is particularly beneficial to the health of patients with ischemic heart disease and atherosclerotic heart disease. The more black the grape skin is, the more flavonoids it contains and the better it protects the heart. Flavonoids contained in grapes are powerful antioxidants that can fight aging.

9. Protect the digestive system: protect the gastric mucosa, prevent and treat gastritis, gastric ulcer and duodenal ulcer.

10. Relieve menopausal syndrome: Menopause is caused by the increase of age and the aging of body tissues, the metabolism of the human body is disordered, and the secretion of endogenous hormones is greatly reduced. The root cause of human aging is caused by excessive free radicals attacking human cells and tissues. OPC can not only remove free radicals and slow down human aging, but also remove the body’s sensitivity to endocrine disorders and reduce menopausal synthesis. Symptoms (such as irritability, sweating, mood disorders, insomnia, etc.).
