Key Word Index-Berchemia racemosa; Rhamnaceae; lignan; aromatic glycoside; nudiposide; secoisolariciresinol glucoside; isotachioside; tachioside; syringic acid glucosyl ester; 13C NMR. Two new aromatic glucosides have been isolated from the stems of Berchemia racemosa together with the known glycosides, nudiposide, (-)-secoisolariciresinol-O-β-D-glucopyranoside and methoxyhydroquinone-1-O-β-D-glucopyranoside (isotachioside).The structures of the new glucosides were found to be β-D-glucopyranosyl syringate, and methoxyhydroquinone-4-O-β-D-glucopyranoside on the basis of chemical and spectral evidences.
