| In order to explore the fatty acid distribution characteristics of wheat grain,the fatty acid contents in grain whole mills of 97 common wheat cultivars/lines were determined by gas chromatography.The results show that,the mean values of total fatty acid content,palmitic (C16∶0),stearic acid (C18∶0),oleic acid (C18∶1),linoleic acid (C18∶2) and linolenic acid (C18∶3) were 1.91%,0.37%,0.02%,0.27%,1.17% and 0.08%,respectively.The content of unsaturated fatty acid (Oleic acid,Linoleic acid and Linolenic acid) was up to 79%.Every kinds of fatty acid fits normal distribution in these wheat grain samples with wide variations.The total fatty acid content was significant correlation with the content of palmitic acid,stearic acid,oleic acid or linoleie acid,respectively.Those results provide a base reference to further improve and utilize the wheat grain fatty acids. |
