From the sterol fraction of seed oil from commercial Cucurbita moschata Dutch (“calabacita”) Δ 5 and Δ 7 sterols having saturated and unsaturated side chain were isolated by chromatographic procedures and characterized by spectroscopic ( 1 H and 13 C‐nuclear magnetic resonance, mass spectrometry) methods. The main components were identified as 24 S ‐ethyl 5α‐cholesta‐ 7,22E ‐dien‐3β‐ol (α‐spinasterol); 24 S ‐ethyl 5α‐cholesta‐ 7,22E , 25‐trien‐3β‐ol (25‐dehydrochondrillasterol); 24 S ‐ethyl 5α‐cholesta‐ 7 , 25‐dien‐3β‐ol; 24 R ‐ethylcholesta‐7‐en‐3β‐ol (Δ 7 ‐stigmastenol) and 24‐ethyl‐cholesta‐ 7 , 24(28)‐dien‐3β‐ol (Δ 7,24(28) ‐stigmastadienol). Lipids 31 , 1205–1208 (1996).
