Resumen
The stem bark of Artabottys venustus yielded 0.34% of crude bases, mostly
known aporphinoids and berbinoids. One of the minor constituents, (-)-artavenustine (12), is
a new member of the rare class of catecholic isoquinoline alkaloids which are of interest as
biogenetic precursors of novel alkaloid types. Its structure was elucidated by spectroscopic
methods, in particular nOeds and 2-D nmr, and by chemical correlation with xylopinine. Other
substances isolated are nornuciferine, asimilobine, anonaine, norstephalagine, norushinsunine,
nuciferine, lirinidine, (S)-reticuline, norcorydine, discretamine, and 10-0-demethyldiscretine
