Process for the production of epigallocatechin gallate (EGCG), green tea fraction, personal care preparation as well as EGCG fraction obtainable by said process

摘要

Epigallocatechin gallate (EGCG) is obtained 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.
