The sterols of Cucurbita moschata ('calabacita') seed oil

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 spectrometr...
