<p>Polyphenol derivative compositions mainly containing oligomers or polymers with monomeric units of formula (I), wherein A is an -OR group, a hydrogen atom or a substituent R; at least a majority of the substituents R are a -COR1 group, where R1 is a straight or branched, optionally saturated alkyl radical with at least two carbon atoms or an aryl, aralkyl or aralkylene radical; the one or more other substituents R which are not a -COR1 group are a hydrogen atom, an alkyl group, a -CO-C6H2-(OH)3 acyl group, a monosaccharide or a polysaccharide; and n1 and n2, which are the same or different, are numbers from 1 to 3, corresponding to the number of substitutions in one ring; and regioisomers and diastereoisomers of said units; said monomeric units being connected by carbon-carbon bonds and/or oxygen bridges between the rings of the flavan nucleus. Said compositions may be used in particular as therapeutical, cosmetic and dietetic oxidation inhibitors.</p> |
