From the hexane and MeOH extracts of Annona coriacea Mart. (Annonaceae) seeds, two novel acetogenins, coriapentocins A and B (1 and 2, resp.) were isolated. The known acetogenin bullacin (3) was also isolated from the hexane extract. The structures of compounds 1 -3 were elucidated by NMR and MS analysis, and relative configurations were established by comparison with literature data.
