Abstract
Complete and unequivocal 1H and 13C 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-d6 solvent have been achieved using the 2D proton–carbon correlation experiments HMQC and HMBC and also 1D NOE difference spectroscopy.
