Three new compounds, a diarylheptanone glucoside (1), 4,5,8-trihydroxy
-alpha-tetralone 5-O-beta-D-[6'-O-(3 '',5 ''-dimethoxy-4 ''-hydroxyben
zoyl)] glucopyranoside (2), and 1,4,8-trihydroxy-3-naphthalenecarboxyl
ic acid 1-O-beta-D-glucopyranoside methyl ester (3), were isolated fro
m the roots of Juglans mandshurica, and their structures were elucidat
ed on the basis of spectroscopic studies including 2D-NMR.
