Title: PROCESS FOR EXTRACTION OF ANTIOXIDANTS FROM PLANT MATERIAL
Abstract:
A process for isolation of at least one antioxidant agent from a plant substrate is disclosed which comprises a) contacting a plant substrate with an aqueous soap extraction solution comprising an aqueous medium and at least one soap compound R-C(=O)O-M+or+M-O(O=)C-R-C(=O)O-M+, wherein R is saturated or unsaturated linear, branched or cyclic C3to C17alkyl or C6to C18aryl, wherein the alkyl or aryl group can be substituted with up to 5 functional groups, and wherein M+is a monovalent cation, to obtain a soap extract and b) isolating an antioxidant mixture comprising at least one antioxidant agent from the soap extract obtained in step a).
