Identification and Quantitation of Fatty Acids in Panicum miliaceum L. by Gas Chromatography-Mass Spectrometry

doi:10.7506/spkx1002-6630-201614022

Abstract

Abstract:

Fourteen fatty acids in Panicum miliaceum L. were qualitatively identified and quantitatively determined using
gas chromatography-mass spectrometry (GC-MS). The total content of these fatty acids was determined to be 96.9%.
Among the identified fatty acids were 8 unsaturated fatty acids (64.533%), of which the predominant ones were linoleic acid
(12.371%), oleic acid (44.157%), linolenic acid (1.173%), etc. Obviously, the dominant fatty acids in Panicum miliaceum L.
were unsaturated fatty acids, which are high quality fatty acids. The results calculated from the regression equation showed
that the contents of palmitic acid, oleic acid, stearic acid, linoleic acid and linolenic acid in Panicum miliaceum L. were
100.261, 165.309, 23.402, 52.181 and 17.516 mg/100 g, respectively. As with other grains such as foxtail millet, sorghum,
wheat, oat and rice, Panicum miliaceum L. contained stearic acid, oleic acid, linoleic acid, palmitic acid and linolenic acid,
rich in unsaturated fatty acids, especially linoleic acid and linolenic acid.

Key words: Panicum miliaceum L., fatty acid, gas chromatography-mass spectrometry (GC-MS)
