products were characterized by one- and two-dimensional nuclear magnetic resonance (1D and 2D NMR) and mass spectroscopy. Compounds 1-5 were then evaluated for their acetylcholinesterase (AChE) inhibitory effect (IC50 = 0.12-1.02 μM). The availability of the synthesized epicatechin derivatives 1-5 via a syntheticroute enabled the first unequivocal identification of these derivatives as tea secondary metabolites
