Process for preparing polyphenolic derivatives (I) or their mixtures or stereoisomers, comprises coupling of a catechin polyphenol or its mixture, with a fatty acid or its derivative in the presence of a lipase catalyst. Process for preparing polyphenolic derivatives of formula (I) or their mixtures comprises coupling of a catechin polyphenol or its mixture, with a fatty acid or its derivative in the presence of a lipase catalyst. R : 10-25C alkyl containing one or more unsaturations or OH. An independent claim is included for polyphenolic derivatives obtained by the process. [Image]. |
