Tetra-acid triglycerides containing a new hydroxy eicosadienoyl moiety inLesquerella auriculata seed oil

  • Published:

Abstract

The seed oil ofLesquerella auriculata contains 32% of a previously unknown fatty acid, 14-hydroxy-cis-11,cis-17-eicosadienoic acid; we propose for it the trivial name “auricolic acid.” In addition, the oil contains 2% densipolic (12-hydroxy-cis-9,cis-15-octadecadienoic) acid, 10% lesquerolic (14-hydroxy-cis-11-eicosenoic) acid and 5% ricinoleic acid. The oil ofL. auriculata is also unusual, because a large part of the total oil consists of triglycerides containing more than three acyl groups. These components were characterized by various chromatographic, spectroscopic and lipolytic techniques.
