Abstract: The fatty acids composition and content in the different organs of Coix lacryma-jobi L from Fujian were measured by gas chromatography. The results showed that, different organs of Coix contain 10 kinds of fatty acids such as linoleic, g-linolenic, palmitic, stearic, oleic, and the fatty acid composition from different organs were different. This paper also discussed the unsaturated fatty acids and saturated fatty acid proportion of Coix organs and their nutritional value.
