A new ellagitannin dimer named euscaphinin was isolated from the leaves of Euscaphis japonica (Thunb.) Kanitz. The structure of this dimer was determined on the basis of spectroscopic and chemical evidence. The resulting structure indicated that it was pr

Four novel dimeric and trimeric hydrolyzable tannins, nupharins C (1), D, (13), E (15) and F (16), which possess a less favorable α-D-glucopyranose core with an atropisomeric (R)- or (S)-hexahydrodiphenoyl group at the 3,6-position, have been isolated from the rhizomes of Nuphar japonicum DC. (Nymphaeaceae).The structures of these compounds were established on the basis of spectroscopic and chemical evidence.Keywords - Nuphar japonicum; Nymphaeaceae; nupharin C-F; dimeric ellagitannin; trimeric ellagitannin; dehydrodigallic acid; α-D-glucose; R-, S-hexahydrodiphenoic acid; atropisomerism; diastereomer
