Enzymatic oxidation of ellagitannin and a new ellagitannin metabolite from Camellia japonica leaves

Enzymatic oxidation of ellagitannin and a new ellagitannin metabolite from Camellia japonica leaves
Polyphenols in the leaves of Camellia japonica L. at different stages of growth were analyzed by HPLC. Pedunculagin [2,3; 4,6-bis-(S)-hexahydroxydiphenoyl-D-glucose] was the major polyphenol in the youngest leaves. The levels of this compound and (+)-catechin decreased as the leaves matured.
