ABSTRACT:
A process is provided for making (−)-epigallocatechin gallate (EGCG) by subjecting a green tea extract to chromatography on a macroporous polar resin, eluting EGCG from the resin with a polar elution solvent, optionally concentrating the eluate, optionally regenerating the resin by desorbing the remaining catechins, and optionally concentrating the desorbed catechins.
