Resveratrol

Resveratrol (grapevine resveratrol-derivatives vine-shoot resveratrol derivatives)

“The Grapevine has played an enormous role in our evolution”

This has been well documented throughout recorded history by civilizations such as the Babylonians, Assyrians, Chinese, Egyptians, Greeks and Romans. Not to mention the volume of research and study papers being generated today.

Sperovine – Formerly Sperovine and known by other names such as Salvestrol, Resveratrol and Vineatrol

Origin of Resveratrol derivatives in red wine.
Resveratrol derivatives are constitutive stilbenes of the woody parts of the plant. They are present in the grape skin as induced substances (induced from woody parts >vine-shoots).

Resveratrol derivatives found in the woody parts of the grapevine which include the vine-shoots are at a concentration of 1000 times greater than those found in the grape skin. The origin of resveratrol derivatives in wine is most likely due to the extraction from grape skin occurring during alcoholic fermentation. Grape-stems are also a potential source of resveratrol derivatives in red wine. The amount of stems in the fermentation process depends upon the method of wine-making being practised: for example manual or mechanical harvesting, destemming or not. An old wine-making practise which is still widely used even in stainless steel tanks consists of putting a bundle of vine shoot at the bottom of the tank. It is used as a filter before the bottom valve. The presence of vine-shoots which contain a large amount of resveratrol derivatives can also contribute to resveratrol derivatives in red wine.

Sperovine – Sperovine® contains vine-shoot derivatives resveratrol oligomers-monomers trans-resveratrol and epsilon-viniferin. These are extracted from vine-shoots (woody parts >vine-shoot >sap) not the grape (fruit). The vine-shoots are grown in the Bordeaux Region of South West France. They are selected and gathered in the months of January to March. The process of extraction is complicated, and is held under patent. So far nine resveratrol derivatives have been identified in these vine-shoots, and research studies continue.
