Compositional variation in seed oils of the Crepis genus

Abstract

Seed oils from eight species of the genus Crepis (family Compositae) fall into three groups differing in chemical composition. Besides conventional fatty acids the oils contain either vernolic acid (47-68%), crepenynic (36-65%), or both (18-35% vernolic and 7-11% crepenynic). Within any one section of the genus, the oils are chemically similar, among the limited groups of samples examined. © 1966 American Oil Chemists' Society.
