Resveratrol Extracts And Its Potency

Resveratrol is an abundant in the grape skin, berries and red wine. It is found in the skin of certain plants such as red grapes, raspberries, mulberries, blueberries, cranberries and red wine. Resveratrol was firstly discovered in the roots of the Japanese Knotweed back in 1940. Resveratrol (3,5,4'-trihydroxystilbene) is an isomeric polyphenolic phytolexin.

Resveratrol ultra is the best natural supplement ever used to treat heart ailmenta and aging. While early resveratrol supplements were produced from grape skins, most products sold today are made from the more economical, and more concentrated, Japanese knotweed (Polygonum cuspidatum).

Most of the supplements contain added red wine extracts, both for their resveratrol ultra content and for marketing purposes. In the typical extraction process, Japanese knotweed roots are sliced before being heated up in large metal chambers known as extractors. The plants are first tested to prevent contamination with heavy metals or chemicals.

The preparation methods is a complex one as it includes many phases. Ethanol or methanol is used as a solvent to separate the resveratrol from the plant tissue, resulting in a crude liquid extract. The separated resveratrol extract is processed further by being run over a column of silica under high pressure, or by various other methods. It is then vacuum-dried to remove the solvent and produce resveratrol powder, which in turn is combined with fillers such as rice flour or hydroxypropylcellulose to manufacture pills and capsules.

The production process is similar to that described above, when used for grapes as well. Alcohol is used to dissolve the resveratrol contained in the skins or seeds, and the resulting liquid is refined further and dried.

A biological method of producing high-quality resveratrol from grapevine cells is the best one. This method is cheaper and more reliable than traditional extraction from grapes. The perceived higher value of grape-based supplements could make this a viable alternative to grapes as a source of premium-grade resveratrol.
