摘　　要：应用气相色谱-质谱分析技术,首次对鹰嘴豆中弱极性成分进行研究。从鹰嘴豆弱极性萃取部位中鉴定了22个化合物,以脂肪酸为主要成分。脂肪酸含量(质量分数)高达81.25%,其中9-十八烯酸和8,11-十八碳二烯酸的含量分别占总量的28.00%和38.60%。Fatty acids and other puny polar components of Cicer arietinum were converted to their methyl ester and detected by GC-MS for the first time. 22 compounds have been identified from the seed of C. arietinum. Fatty acids are the main components. The content of fatty acids is 81.25%, and the contents of 9-octadecenoic acid （z）-methylester and 8, 11-octadecadienoic acid methylester are 28.00% and 38.60% respectively. This result indicated that the unsaturated fatty acids are rich in the seed of C. arietinum.
