| Abstract: | A new megastigmane diglycoside, inamoside 6′-O-l-α-arabinofuranoside (cuneatoside), was isolated from the leaves and branches of Erythroxylum cuneatum together with seven known compounds, (+)-catechin, quercetin 3-O-α-l-rhamnoside, apocynol B, (6S,9R)-roseoside, vomifoliol 9-O-α-l-arabinofuranosyl (1 → 6)-β-d-glucopyranoside, inamoside, and citroside A The structural elucidations were based on analyses of physical and spectroscopic data. |
