Product Details

Grape Seed Extract Overview:

Grape seed extract is rich in proanthocyanidins. The quality of grape seed extract is measured by the content of proanthocyanidins in proanthocyanidins. Generally, grape seed extract contain 95% proanthocyanidins, but the efficacy varies with product. Ingestion of food or beverages rich in proanthocyanidins can lead to a feeling of mouth shrinkage and dehydration, i.e. astringency, which is similar to the feeling after having some alcoholic beverages.

Grape seed extract contains flavonoids, has antioxidant properties, and is used to reduce low-density lipoprotein or bad cholesterol levels, relax blood vessels, and reduce the risk of coronary heart disease. The antioxidants in grape extract help prevent heart disease and have other potentially beneficial effects. Grape seed extract can reduce inflammation and has astringent effects. Grape seed extract can gather tissues together and help stop bleeding and diarrhea.



It is mainly composed of polyphenols, such as proanthocyanidins, catechins, epicatechins, gallic acid, and epigallocatechin gallate.


Extraction Method:

The properties of grape seed extract rely on the extraction process and how the grapes are grown. The typical method is extraction with acetone, acetonitrile, ethyl acetate, methanol and other organic solvents. Another method is hot water extraction. The combination of high performance liquid chromatography (HPLC) and proton magnetic resonance (PMR) spectroscopy is the most effective analysis method.

Benefits of grape seed extract:

Grape seed extract helps lower blood pressure, especially for middle-aged and overweight people.

Grape seed extract is used to promote blood flow and reduce the risk of blood clotting, which may benefit people with circulatory disorders.

Grape seed extract helps prevent damage caused by oxidative stress and inflammation, and promotes kidney health.


Function and usage:

1. Grape seed extract is a pure natural substance and one of the most effective plant-derived antioxidants found currently. Tests show that its antioxidant effect is 30-50 times that of Vitamin C and Vitamin E.

2. Proanthocyanidins have strong activity and can inhibit carcinogens in cigarettes. Their ability to capture free radicals in the water phase is 2-7 times that of ordinary antioxidants, such as more than twice the activity of α-tocopherol.
