Abstract

Five oxindole alkaloids, three plumerane-type alkaloids, subtype haplophitine, and one aspidospermatane-type alkaloid, subtype tubotaiwine, were isolated from the medicinal plants Aspidosperma rigidum and A. schultesii. One compound was identified as the transoid conformer of 18-oxo-O-methylaspidoalbine which was not previously described. The antiparasitic activity of all compounds against Trypanosoma cruzi and Leishmania infantum and their non-specific cytotoxicity against mammalian cells were also determined.
