title: Acetogenins, Aporphinoids, and Azaanthraquinone from Annona cherimolia Seeds.
abstract: We have isolated several known steroids, glycosides, isoquinoline, and azaanthraquinone alkaloids, and five acetogenins belonging to a new group of secondary metabolites, the bis-tetrahydrofuran gamma-lactones, from the seeds of ANNONA CHERIMOLIA. The azaanthraquinone alkaloid isolated was identified as cleistopholine. One new acetogenin is reported here: laherradurine; a second new one was isolated, but its structure has not been determined. The other three: cherimoline, dihydrocherimoline, and asimicine have already been reported.
