To study the fatty acid composition and analysis the variation among the samples of tang oil collected from Guangxi, Chongqing, Hunan, Hubei and Guizhou Provinces of China. Gas chromatography-mass spectrometry(GC-MS) were employed to determine the fatty acid composition of tung oil. The results show that the main composition of the tung oil in China are n-hexadecanoic acid, linoleic acid, oleic acid, stearic acid, alpha-octadecatrienoic acid, beta-octadecatrienoic acid. Tung oil contains octadecatrienoic acid 72.56 similar to 88.59% and polyunsaturated fatty acids 80.26 similar to 92.39%. The content of octadecatrienoic acid and polyunsaturated fatty acids in tung oil are different between different regions and different varieties.
