Identity and configuration of conjugated fatty acids in certain seed oils

Abstract

Punicic acid was found in the seed oils of Cayaponia grandifolia, Trichosanthes cordata and T. cucumerina. α-Eleostearic acid was found in Momordica cochinchinensis, M. cochinchinesis variety mixta and M. cymbalaria. The identity of the conjugated triene acid of Aleurites trisperma, Garcia nutans and Cyclandrophora laurina was confirmed as α-eleostearic acid (cis, trans, trans configuration). The configuration of kamlolenic acid was proved to be cis-9, trans-11, trans-13. The oils of Aleurites remyi and Licania platypus did not contain any conjugated acid. © 1969 American Oil Chemists' Society.
