Abstract

A new sesquilignan glycoside, syringylglycerol-β-syringaresinol ether 4' '4''', -di-Ο-β-D-glucopyraRoside (1), and a new neolignan glycoside, dehydrodiconiferyl alcohol 4, γ'-di-Ο-β-D-glucopyranoside (2), were isolated from the bark of Eucommia ulmoides Ouv. (Eucommiaceae), together with a known neolignan glycoside, citrusin B (3). Their structures were determined on the basis of chemical evidence and spectroscopic analyses.
