[en] Leaves and stem barks of S. SCHEFFLERI G ILG afforded eight dihydroindole alkaloids. Four tertiary monomers (O-methyl Na-acetylstrychnosplendine, Na-acetylstrychnosplendine, strychnobrasiline and strychnofendlerine) have been isolated from leaf material while stem barks yielded one tertiary monomer (desacetylisoretuline), one tertiary symmetrical dimer (bis-nordihydrotoxiferine) and two quaternary monomers (mavacurine and fluorocurine).
