Zusammenfassung:	Processes for preparing water soluble and oil soluble antioxidant compositions extracted together from Labiatae herbs in a single extraction using an alcohol and water solvent, followed by a simple, yet effective purification step that allows the separation of the water soluble antioxidative fractions containing mainly rosmarinic acid from antioxidative fractions containing mainly carnosic acid and carnosol, without cumbersome acid/base partitioning steps. L'invention concerne des procédés de préparation de compositions antioxydantes solubles dans l'eau et solubles dans l'huile extraites ensemble d'herbes Labiatae par une extraction individuelle utilisant un solvant alcool et eau, suivie par une étape de purification simple mais efficace qui permet la séparation des fractions antioxydantes solubles dans l'eau contenant principalement de l'acide rosmarinique de fractions antioxydantes contenant principalement de l'acide carnosique et du carnosol, sans étapes de séparation acide/base difficiles.
