Kamlolenic acid and other conjugated fatty acids in certain seed oils

Abstract

The major fatty acid of the seed oil of Trewia nudiflora is shown to be α-kamlolenic acid, not α-eleostearic acid as believed earlier. Other conjugated acids were found and identified in seed oils not previously studied, viz., α-eleostearic acid in Parinari insularum and Ricinodendron rautanenii; trans,8-trans,10-cis,12-octadecatrienoic acid in Calendula stellata. The identity of the conjugated acids in four other seed oils was established, viz., α-eleostearic acid in Prunus yedoensis and Valeriana officinalis; punicic acid in Cucurbita digitata and C. palmata. © 1966 The American Oil Chemists' Society.
