NOVEL FLAVONE GLYCOSIDE DERIVATIVES FOR USE IN COSMETICS, PHARMACEUTICALS AND NUTRITION

摘要

The invention relates to flavone and isoflavone glycoside derivatives of general formula (I): [A1-C(=O)O]m-[X-O-Z]-[O-C(=O)-A2]n (I), wherein [X-O-Z] represents a flavone or isoflavone glycoside structure, wherein X represents a flavone or isoflavone parent substance of formula (IIa) or (IIb), said (iso)flavone parent substance being mono- or multisubstituted and/or mono- or multireduced (hydrogenated), wherein Z (sugar) represents a mono-, di- or polysaccharide which is acetally bonded to the radical X and is ester-substituted with A2 n-times, [A1-C(=O)] representing an acyl radical on the flavone or isoflavone parent substance, wherein A1 and A2, independently of each other, represent a polyunsaturated C15- C25- alkenyl radical with at least 4 isolated and/or at least 2 conjugated double bonds or an arylaliphatic radical with 1-4 methylene groups between the ester group and the aromatic ring, wherein [C(=O)A2] represents an acyl radical on the sugar Z, wherein n is a whole number (1, 2, 3, ...) but not 0, wherein m is a whole number including 0 (0, 1, 2, 3, ...) and wherein R1, R2 and R3 represent hydroxyl groups or hydrogen atoms.
