Feroniellide A has a novel dioxabicyclic [3.2.1]octane moiety, and feroniellide B is the C-3 epimer of the known triterpenoid 3. Their overall structures and relative configurations were established by combined spectral data analysis. The cytotoxicity of 1 and 2 was also evaluated against human KB and HeLa carcinoma cells. © 2006 Elsevier Ltd.
