Four lignan xylosides and two neolignan glycosides were isolated from the stem and root barks of Ulmus davidiana var. japonica. Their structures were identified as lyoniside, nudiposide, 5'-methoxyisolariciresinol-9'-O-beta-D-xylopyranoside, isolariciresinol-9'-O-1-D-xylopyranoside, rel-trans-dihydrodehydroconiferyl alcohol 4'-O-alpha-L-rhamnopyranoside and icariside E3 by comparison of their spectral data with those reported in the literatures, respectively.
