Abstract: Substituted and unsubstituted flavone or isoflavone glycoside derivatives of the formula [A1-C(?O)O]m—[X—O-Z]—[O—C(?O)-A2]n, wherein [X—O-Z] represents a flavone or isoflavone glycoside structure, particularly a naringin residue, X is a flavone or isoflavone corresponding to formula (IIa) or formula (IIb): wherein the flavone or isoflavone residue is substituted one or more times and/or reduced one or more times; Z represents a mono-, di- or polysaccharide, which is acetally-bound at the benzopyran group to X and ester-substituted by —O—C(?O)-A2; [A1-C(?O)] is an acyl group on the flavone or isoflavone; A1 and A2 independently, represent a polyunsaturated C15-26 alkenyl group containing at least four isolated and/or at least two conjugated double bonds, or an arylaliphatic radical with 1-to-4 methylene groups between the ester group and the aromatic ring; [C(?O)A2] is an acyl group; n is an integer other than 0; m is an integer, including 0; and R1, R2 and R are hydroxyl groups or hydrogen atoms.

Abstract: 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&rs
