摘要：

Complete and unequivocal H-1 and C-13 NMR assignments for a range of green tea polyphenols /epiafzelechin, catechin, epicatechin, gallocatechin, epigallocatechin, catechin-3-O-gallate, epicatechin-3-O-gallate, gallocatechin-3-O-gallate, epigallocatechin-3-O-gallate and epigallocatechin-3-O-(3'-O-methyl)-gallate/ in acetone-d(6) solvent have been achieved using the 2D proton-carbon correlation experiments HMQC and HMBC and also 1D NOE difference spectroscopy.
