The shrub S. odoratissima was collected at Mucugê (Chapada Diamantina - Bahia, Brazil). Its rhizome was extracted by maceration with CH2Cl2 and supercritical CO2. The supercritical extraction supplied a coumarin, 8-prenyl-7geranyloxycoumarin. Another coumarin, the auraptene, and an alkaloid, skimmianine, were obtained from the CH2Cl2 extract. The structures of the compounds were elucidated based on spectroscopic studies, and by comparison with literature data.
