Resveratrol is situated in the skins and seeds of grapes, and also in blueberry, mulberries, cranberries and nuts, and in the roots of white hellebore and Japanese knotweed. While early resveratrol products were created from grape skins, most products sold now are manufactured from the more affordable, and more concentrated, Japanese knotweed. This plant extraction can also be known in Japan as kojo kon, and in China as Hu Zhang. Some nutritional supplements contain added red wine extracts, both for their resveratrol content and for advertising functions. At the typical mining process, Japanese knotweed roots are cut before being heated up in big alloy chambers known as extractors.

The plants are first examined to prevent pollution with heavy metals or compounds. Ethanol or methanol is employed as a solvent to individual the resveratrol from the plant extraction tissue, leading to a crude liquid extract. The detached resveratrol extract is prepared more by being go beyond a line of silica under high pressure, or by various other systems. It is then vacuum dry to remove the solvent and make resveratrol powder, which in turn is along with fillers like rice flour or hydroxypropylcellulose to manufacture tablets and capsules. When grapes are utilized to make resveratrol, the generation process is comparable to that described above.

Alcohol is employed to dissolve the resveratrol found in the skins or seeds, and the resultant liquid is refined further and dry. Due to the low relative content of resveratrol in grapes, products made solely from grapes are extremely expensive to produce. Scientists at the University of Alicante in Spain have now developed a biological approach to creating top quality resveratrol from grapevine cells. This method is cheaper and much more reliable than conventional plant extraction from grapes.
