Model No.:GRS Product Name: Grape seed P.E. Plant Origin: Vitis vinifera Specification: Proanthocyanidins 95% UV 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. We have a GMP certified extract factory to produce all kinds of herbal extract. We possess a complete set of advance equipment for extraction,refinement,column chromatoraphy,condensation and desiccation. Our quality control laboratory is well equipped with most advanced instruments,such as HPLC,UV,GC,AA etc. Action: 1) Grape seed extract (GSE) and oligomeric proanthocyanidins (OPCs) clearly possess remarkable antioxidant properties. 2) Their effects on reducing free radical damage and oxidative stress suggest that they may be particularly effective in reducing the risk of cancer, cardiovascular disease and a number of the chronic diseases associated with aging.
