Kamlolenic acid and other conjugated fatty acids in certain seed oils

Abstract

Abstract The major fatty acid of the seed oil of Trewia nudiflora is shown to be ॅ‐kamlolenic acid, not ॅ‐eleostearic acid as believed earlier. Other conjugated acids were found and identified in seed oils not previously studied, viz., ॅ‐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., ॅ‐eleostearic acid in Prunus yedoensis and Valeriana officinalis ; punicic acid in Cucurbita digitata and C. palmata .
