摘要：

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