چکیده
O estudo fitoquímico de Acanthus arboreus resultou no isolamento de 3 novos alcalóides: 6hidróxi-2-benzoxazolinona, 4-hidróxi-acantamina (3,4-di-hidróxi-1,4-benzoxazino-2-ona) e acantaminosídeo (3-O-glicopiranosídeo-1,4-benzoxazino-2-ona). Além destes alcalóides foi também isolado o novo flavonóide 7-O-β-D(6”-trans-p-cumaroil)3”-O-acetilglicopiranosídeo apigenina e os seguintes compostos de estruturas já conhecidas: apigenina, 7-O-β-D(6”-trans-p-cumaroil)3”-Oglicopiranosídeo apigenina, ácido vanílico, lupeol, estigmasterol e 3-β-glicopiranosídeo sitosterol. As estruturas dos compostos foram determinadas por métodos espectroscópicos e transformações químicas.
