Saff. (Annonaceae). The ethanol extract yielded O-methylmoschatoline, isolated for the first time in this species, and stepholidine, reported for the first time in genus Fusaea. The structural identification of the alkaloids was made based on the analysis of their NMR spectra. Through the use of GC and GC-MS, two sesquiterpenoids, a-cadinol (12.5%) and spatulenol (12.0%) were identified as the major constituents of the essential oil.engAcesso AbertoAlcalóidesFusaea longifoliaAnnanoceaeCompostos voláteisBelém - PAPará - EstadoAmazônia brasileiraArtigo de Periódico
