The description: 
Grape seed extract (GSE) is just what it sounds like an extract from grape seeds. The seeds are typically from red grapes (instead of white), which have a high content of compounds known as oligomeric proanthocyanidins (OPCs). 

The OPCs are also present in a wide variety of fruits and vegetables, including pine bark (Pycnogenol) and green tea, where, like grape seed extract, they possess potent antioxidant properties. The OPCs are chemically known as flavonoids or polyphenols, which can differ substantially based on their polymer arrangement 

Functions: 
1.Woundhealing —- OPCs induce dvascular endothelial growth factor and accelerated healing of injured skin in mice.

2. Tooth decay -- seed phenolics may inhibit oral sugar metabolism and retard growth of certain bacteria that cause dental caries

3. Osteoporosis -- grape seed extracts enhanced bone density and strength skin cancer -- grape seed proanthocyanidins decreased tumor numbers and reduce the malignancy of papillomas

4. Ultraviolet damage to skin -— dietary proanthocyanidins may protect against carcinogenesis and provide supplementation for sunscreen protection

Applications:

Medicine, cosmetics, dietary supplement, food additive.
