Cytotoxic Compounds from the Roots of Juglans mandshurica

Abstract
Three new compounds, a diarylheptanone glucoside (1), 4,5,8-trihydroxy-α-tetralone 5-O-β-d-[6‘-O−(3‘‘,5‘‘-dimethoxy-4‘‘-hydroxybenzoyl)]glucopyranoside (2), and 1,4,8-trihydroxy-3-naphthalenecarboxylic acid 1-O-β-d-glucopyranoside methyl ester (3), were isolated from the roots of Juglans mandshurica, and their structures were elucidated on the basis of spectroscopic studies including 2D-NMR.
