摘　　要：用乙醚／正己烷混合溶剂萃取榛子中的脂肪酸甘油酯，用氢氧化钾－甲醇法甲酯化，以气相色谱－质谱法测定脂肪酸组成，共检出４种脂肪酸，其中以油酸（８１．０％）、亚油酸（１７．５８％）为主．Samples of hazelnut were extracted with a mixed solvent of ether and n hexane,and esterfied with potasium hydroxide methyl alcohol.Then they were determined by capillary gas chromatography mass spectrography,and four fatty acids were found with the following composition:plamilic acid:1.10%,linoleic acid:17.58%,oleic acid:81.0%,stearic acid:0.29%.
