Phytochemical investigation on the aerial parts of Senecio hadiensis Forssk. led to the isolation of two new sesquiterpenoids, presilphiperfolan-2α,5α,8α-triol (1) and presilphiperfolan-2α,5α,8α,10α-tetraol (2) featuring the rare presilphiperfolane-type frameworks. The structures of 1 and 2 were elucidated on the basis of extensive spectroscopic (1D- and 2D-NMR, HR-ESI-MS) methods and by comparison with the literature data. The isolates 1 and 2 were evaluated in-vitro for antiinflammatory, cytotoxic, and peroxisome proliferator activated receptor alpha and gamma (PPARα and PPARγ) agonistic activities.
