Of 12 Gymnospermae seed and leaf oils, only 2 contained cyclopropene fatty acids. All-cis 5, 11, 14, 17-eicosatetraenoic acid occurred in concentrations up to 11.9% in 6 seed oils, and up to 61% in 2 leaf oils. The structure of this acid, as its meth

When in contact with silver nitratesilica gel, methyl esters of cyclopropene fatty acids undergo ring opening to yield pairs of isomers with methylene, hydroxymethyl, or nitratomethyl side-chains at the original ring positions. Thus the main products

AnalyzingSantalum obtusifolium seed oil led to the identification of 12 fatty acids; only ximenynic (71.5%) and oleic (14.3%) acids were present in substantial amounts. Data on the mass spectrum and1H- and13C-NMR (nuclear magnetic resonance) spectra
