Abstract:
The stem bark of ODYENDYEA GABONENSIS Engl. (Simaroubaceae) has yielded five quassinoids, identified as ailanthinone ( 1), 2'-acetoxyglaucarubinone ( 2), glaucarubinone ( 4), 2'-acetoxyglaucarubin ( 5) and excelsin ( 6), the simple coumarin scopoletin and the alkaloid 8-hydroxycanthin-6-one ( 3). Highfield (1)H- and (13)C-NMR spectra were recorded where possible and results are tabulated.
