PROCESS FOR SCAVENGING PHYTOCHEMICALS

摘要

A process comprises the steps of: providing a natural (e.g. plant) material; extracting a first sample of the material with a polar solvent to produce a polar extract and a non-polar residue; subjecting the polar extract to ion-exchange chromatography to produce an extract enriched in ionic-compounds and a non-ionic residue; subjecting the non-ionic residue to hydrophobic interaction or reversed-phase chromatography to produce a scavenged non-ionic extract depleted in sugars; and chromatographically fractionating the scavenged extract to yield one or more scavenged fractions comprising one or more non-ionic (phyto)chemical(s).
