Abstract
The oxacanthin alkaloid components of Quassia kerstingü L. have been found to be 2-hydroxy- and ll-hydroxy-canthin-6-one (1a and 1b). Structure 1a was confirmed by results of methylation (1a → 1c + 2a) and NOE studies. A selective INEPT NMR technique was employed to support unequivocally the 11-hydroxy-canthin-6-one (1b) assignment.
