Abstract

Two new products, EGCG-MOx-D5 (3) and EGCG-MOx-D6 (4), on the oxidation of (-)-epigallocatechin gallate (EGCG) (1) in its aqueous solution were isolated and their structures were elucidated. These structures and those of previously established ones suggested the pathways of the changes in the oxidation. Rapid decrease of 1 accompanied by the formations of the oxidative products suggested the participation of these products in the biological and pharmacological effects reported to be those of 1.
