Some Wrong Statements about Resveratrol
It is possible to produce resveratrol from red wine: > WRONG
To produce 1 kg of an extract containing 5% resveratrol, you need 10,000 litre of red wine.
It is possible to produce resveratrol from grape: > WRONG
The resveratrol content of grape extracts is between 100 to 2500 ppm, 20 times less than Vineatrol®
It is possible to produce a grape extract containing only trans-resveratrol: > WRONG
Epsilon-viniferin is the main metabolite of resveratrol produced by Vitis Vinifera.
All the extracts of the plant Vitis Vinifera which contain resveratrol, also contain epsilon-viniferin: for example red wine, grape extracts, Grape Vine Resveratrol.
The separation of Resveratrol and epsilon-viniferin is very hard and is only possible by preparative HPLC.
In a Vitis Vinifera extract, the epsilon-viniferin content must be higher than 0.2 times (minimum, than that of the resveratrol content. If not, the extract obviously contains additional T-Resveratrol from another source.
