The oxacanthin alkaloid components of Quassia kerstingii L. have been found to be 2-hydroxy- and 11-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.
