Two new cytotoxic, nonadjacent bis-tetrahydrofuran acetogenins, cherimolin-2 and almunequin, have been isolated from the bioactive methanolic extract of Annona cherimolia seeds. In addition to these new compounds, the structure of the known acetogenins, cherimolin-1, laherradurin and otivarin (ex-dihydrocherimolin), are here revised. The structures were established by means of one- and two-dimensional NMR experiments. All compounds exhibited potent cytotoxic and antiparasitic activities.
