Abstract

The Guianese Annonaceous plant Guatteria ouregou DUN. has yielded fourteen isoquinoline alkaloids, five of which are novel. They belong to several structural types; attention is specially drawn to three original skeletons, namely 7-hydoxy-7-methyl aporphinoids, 7-gem-dimethyl aporphinoids and α-gem-dimethyl cularinoids. The results concerning solvent shift in 1H NMR spectra of some of these alkaloids are emphasized. Finally the phytochemical significance of the isolated alkaloids is discussed considering their chemotaxonomic and biogenetic interest.
