Abstract
The present invention relates to a method of isolating phenolic secondary plant constituents from plant material using a microporous membrane which displays affinity ligands for the phenolic secondary plant constituents.
Claims14
A method of isolating phenolic secondary plant constituents from plant material, comprising the steps of:
- (a) providing homogenized plant parts as a plant extract which comprises phenolic secondary plant constituents,
- (b) bringing the plant extract into contact with a microporous membrane which has affinity ligands for the phenolic secondary plant constituents, whereby the phenolic secondary plant constituents are adsorbed on the membrane, and
- (c) eluting the phenolic secondary plant constituents from the membrane,
- whereby a solution comprising the phenolic secondary plant constituents is obtained wherein the affinity ligand of the membrane is selected from the group consisting of boronates and metal chelates.

A method of isolating phenolic secondary plant constituents from plant material, comprising the steps of:
- homogenizing plant material to provide a suspension of homogenized plant parts as a plant extract which comprises phenolic secondary plant constituents;
- then without clarifying the suspension
- bringing the suspension of homogenized plant parts into contact with a microporous membrane which has affinity ligands for the phenolic secondary plant constituents, whereby the phenolic secondary plant constituents are adsorbed on the membrane;
- and then
- eluting the phenolic secondary plant constituents from the membrane as a solution comprising the phenolic secondary plant constituents wherein the affinity ligand of the membrane is selected from the group consisting of boronates and metal chelates.
