Abstract

La présente invention se rapporte à nouveau procédé d'extraction d'oligomères flavanoliques présents dans les végétaux. Le procédé se caractérise en ce que l'on extrait un végétal par un mélange acétone-eau contenant de 3 à 4 volumes d'acétone par volume d'eau. Les extraits obtenus sont essentiellement utiles comme médicaments.The present invention relates to a new process for extracting flavanolic oligomers present in plants. The process is characterized in that a plant is extracted with an acetone-water mixture containing 3 to 4 volumes of acetone per volume of water. The extracts obtained are mainly useful as medicaments.
