Acutissimin A

Acutissimin A is a flavono-ellagitannin, a type of tannin formed from the linking of a flavonoid with an ellagitannin.

In 2003, scientists at Institut Européen de Chimie et Biologie in Pessac, France found that when the oak tannin vescalagin interacts with a flavanoid in wine acutissimin A is created. In separate studies this phenolic compound has been shown to be 250 times more effective than the pharmaceutical drug Etoposide in stopping the growth of cancerous tumors.[1][2][3]

While it would be quite inappropriate to infer from the presence of acutissimin A in red wine that this beverage possesses antitumor properties, our work shows for the first time that wine contains polyphenolic molecules displaying both ellagitannin and flavanoid structural features.
