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; and chromatographically fractionating the enriched extract to yield one or more polar fractions comprising one or more ionic (phyto)chemical(s).
