Two new Aspidosperma-Aspidosperma-type bisindole alkaloids, hazuntiphyl-lidine and anhydrohazuntiphyllidine {4], have been isolated from the leaves of Hazunta modesta var. modesta subvar. divaricata. Their structures were established by spectroscopic means. In solution, hazuntiphyllidine was found to occur in two distinct structural forms 2 or 3 depending upon the solvent used. © 1991, American Chemical Society. All rights reserved.
