Two new sesquiterpenoid derivatives, attributable to the eudesmane type (1, named septemlobin E) and the vetispirane type (2, named septemlobin F), were isolated from the whole plant of Solanum septemlobum. Their structures were elucidated on the basis of integrated spectroscopic techniques, mainly HR-FAB-MS and 1D and 2D NMR (1H–1H COSY, HMQC, HMBC, and ROESY). In vitro, the two sesquiterpenoid derivatives were found to show significant cytotoxicity against three cancer cell lines (P-388, HONE-1, and HT-29), and gave IC50 values in the range 3.0–7.1 μM.
