MANUFACTURING METHOD OF GALLOCATECHIN GALLATE BY EPIMERIZATION OF EPIGALLOCATECHIN-3-GALLATE

摘要

The present invention relates to a method for the preparation of gallocatechin gallate through epimerization of epigallocatechin-3-gallate by heat. In particular, the solubility of epigallocatechin-3-gallate is increased using organic solvent and the pH of the solvent is controlled, and then heated. The present invention enables production of gallocatechin gallate for industry by increasing its conversion rate.
