Two new hydrolyzable tannins, named coriariins A and B, have been isolated from the leaves of Coriaria japonica A. gray along with l,2,3-tri-0-galloyl-²-D-glucose, geraniin, tellimagrandins I (1) and II (2), and rugosins A, D and E. The structure 3 of coriariin A, which is a dimer of 2, and the structure 4 of coriariin B, a related monomer, have been established on the basis of spectroscopic and chemical evidence.
