Argylia radiata (L.) D. Don (Bignoniaceae) represents an important source of secondary metabolites, largely unexplored. The paper presents the isolation from the plant root of two new monoterpene alkaloids, 10-acetoxy-actinidine and 4-nor-7,8-dehydro-10-hydroxy-skytanthine, whose structures were elucidated by Mass spectrometry and 1H-NMR data.
