Production of new or known tri-O-hydroxyalkyl quercetin or isoquercetin derivatives, e.g. useful as food supplements, comprises enzymatic hydrolysis of tri-O-hydroxyalkyl rutin derivatives in an aqueous medium

摘要

The production of tri-O-hydroxyalkyl quercetin or isoquercetin derivatives (I) comprises enzymatic hydrolysis of tri-O-hydroxyalkyl rutin derivatives (II) in an aqueous medium. The production of tri-O-hydroxyalkyl quercetin or isoquercetin derivatives of formula (I) comprises enzymatic hydrolysis of tri-O-hydroxyalkyl rutin derivatives of formula (II) in an aqueous medium. R<1> = OH or a group of formula (i); and m, n, p = 2-8. An Independent claim is also included for tri-O-hydroxyalkyl isoquercetin derivatives of formula (I) where R<1> is a group of formula (i).
