Abstract
Four new hydrolyzable tannins, coriariins G, H, I and J, were isolated from the leaf of Coriaria japonica (Coriariaceae). Structures 1,2 and 3, having a sedoheptulose residue, were assigned for coriariins G, H and I, respectively. Structure 4, having a depsidone-forming dehydrodigalloyl group, was assigned for coriariin J, based on the chemical correlation with coriariin B (5). The orientation of the dehydrodigalloyl group in 5 was confirmed by 1H-13C long-range shift-correlation spectroscopy.
