title: Cuneatoside, a new megastigmane diglycoside from Erythroxylum cuneatum Blume.
abstract: A new megastigmane diglycoside, inamoside 6'-O-L-alpha-arabinofuranoside (cuneatoside), was isolated from the leaves and branches of Erythroxylum cuneatum together with seven known compounds, (+)-catechin, quercetin 3-O-alpha-L-rhamnoside, apocynol B, (6S,9R)-roseoside, vomifoliol 9-O-alpha-L-arabinofuranosyl (1-->6)-beta-D-glucopyranoside, inamoside, and citroside A The structural elucidations were based on analyses of physical and spectroscopic data.
