Abstract
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.
