Abstract: Gallic acid (1), ellagic acid (2), and 4 hydrolysable tannins, 1,2,6-tri-O-galloyl-β-D-glucose (3), 1,3,6-tri-O-galloyl-β-D-glucose (4), 1,2,4,6-tetra-O-galloyl-β-D-glucose (5) and 1,2,3,4,6-penta-O-galloyl-β-D-glucose (6) have been isolated from the H2O fraction of acetone-H2O (7:3) extract of Juglans mandshurica Maxim. stem bark on the basis of chemical evidence and spectral techniques. Compounds 2, 4 and 6 were reported for the first time from this species.

Key words: Juglans mandshurica Maxim., bark, hydrolysable tannin, NMR
