Abstract

Abstract: Prunus mira kernels from nine Tibetan growing areas were analyzed for oil extraction yield and fatty acid composition using solvent reflux extraction and gas chromatography (GC). Results showed that the oil extraction yield from P. mira kernels varied significantly among different growing areas with an average of 44.96%. P. mira kernel oil was extremely rich in unsaturated fatty acids with an average of 90.901%, mainly oleic acid and linoleic acid. Oleic acid varied between 45.280% and 71.360% and was the most abundant fatty acid in the samples from Mangkang county, and linoleic acid ranged from 18.010% to 44.340%, showing the highest value in the samples from Yadong county. The mean content of saturated fatty acids was 9.099%, mainly palmitic acid and stearic acid, with palmitic acid ranging from 5.829% to 7.354% and showing the highest value in the samples from Yadong county, and stearic acid varying in the range of 1.600%–3.034% and being the most abundant saturated fatty acid in the samples from Chayu county. Clustering analysis based on the contents of 11 fatty acids indicated that P. mira kernel oils from Minling, Zuogong, Bomi, and Basu counties were similar while P. mira kernel oil from Mangkang county was quite different from those from other areas.

Key words: Tibet, Prunus mira kernel, oil extraction yield, fatty acid composition
