%X phytochemical study of acanthus arboreus resulted in the isolation of three novel alkaloids: 6-hydroxy-benzoxazolinone, 4-hydroxyacanthamine and acanthaminoside. in addition, a new acyl flavonoid apigenin-7-o-b-d-(6"-trans-p -coumaroyl)-3"-o-acetyl glucopyranoside was also isolated. the known compounds were identified as apigenin, apigenin-7- o-b-d-(6"-trans-p-coumaroyl) -glucoside, vanillic acid, lupeol, stigmasterol and sitosterol glucoside. the structures were determined by physical, chemical and spectral techniques.
