ABSTRACT:
An antioxidant composition is obtained by subjecting a spice to at least one extraction with a non-polar solvent, after which the residue from the spice thus extracted is subjected to at least one extraction with a polar solvent and the extract obtained from each extraction with the polar solvent is concentrated and dried to obtain the antioxidant. Additionally, the extract obtained from the non-polar solvent extractions may be mixed with a basic aqueous solution, after which the aqueous phase of the mixture is acidified and then extracted with dichloromethane, and the extract so obtained may be combined with the extract obtained from the polar solvent extractions, concentrated and then dried.
