A new lignan glycoside was isolated from the bark of Eucommia ulmoides OLIV. (Eucommiaceae) and its structure was established as (+)-1-hydroxypinoresinol 4"-O-β-D-glucopyranoside (1) on the basis of chemical evidence and spectroscopic studies. An isomer of 1, (+)-1-hydroxypinoresinol 4'-O-β-D-glucopyranoside (2), was also isolated, together with (±)-erythro-, and (±)-threo-guaiacylglycerol (3 and 4), (+)-cyclo-olivil (5) and (-)-olivil (6).
