Triglyceride compounds isolated from jojoba seed oil by column chromatography were composed predominantly of C-18, C-20, C-22, and C-22, and C-24 n-9 fatty acids with minor amounts of saturated C-16. Chain length and double-bond positions were determined by gas-liquid chromatography and gas-liquid chromatography-mass spectrometry of the corresponding methyl ester and picolinyl ester derivatives. Triglyceride structures were analyzed directly by ion trap mass spectrometry. The analysis of minor compounds can provide highly specific information about the identity of an oil.
