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 1H- and 13C-NMR spectra were recorded where possible and results are tabulated.
