The Fatty Acid Composition of Gymnospermae Seed and Leaf Oils of Gymnospermae Seed and Leaf Oils

Abstract

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 methyl ester, was established by the combination of physical (UV, IR, 1 H- and 13 C- NMR and mass spectra) and chemical techniques. Arachidonic acid also occurred in 2 seed oils.
