Abstract

The second component “b” (ECL value 16.25) in the multibranched-chain fatty acids, separated earlier from whale oils, was identified by gas-liquid chromatography as 2, 6, 10, 14-tetramethylpentadecanoic acid, which was synthesized from phytol and confirmed by means of infrared absorption, high resolution nuclear magnetic resonance, and mass spectrometry.<BR>It is estimated that this acid in the fin whale blubber oil used in this investigation corresponded to approximately 0.05% of the total weight of fatty acids.<BR>The acid also existed as a constituent of the oils from sperm whale blubber as well as blue whale bone and sei whale blubber, as previously reported.
