| Sumario: | From the sterol fraction of seed oil from commercial Cucurbita moschata Dutch ('calabacita') Δ5 and Δ7 sterols having saturated and unsaturated side chain were isolated by chromatographic procedures and characterized by spectroscopic (1H and 13C-nuclear magnetic resonance, mass spectrometry) methods. The main components were identified as 24S-ethyl 5α-cholesta- 7,22E-dien-3β-ol (α-spinasterol); 24S-ethyl 5α-cholesta-7,22E,25-trien- 3β-ol (25-dehydrochondrillasterol); 24S-ethyl 5α-cholesta-7,25-dien-3β- ol; 24R-ethyl-cholesta-7-en-3β-ol (Δ7-stigmastenol) and 24-ethyl-cholesta- 7,24(28) dien-3β-ol (Δ(7,24(28))-stigmastadienol). |
