摘　　要：用混合溶剂抽提葡萄籽中的脂肪酸,BF3-CH3OH酯化,GC-M S法测定了葡萄籽中脂肪酸组成、分布.鉴定出42种脂肪酸,其中不饱和脂肪酸占全部脂肪酸的73.28%,亚油酸的含量高达62.38%,油酸含量为7.88%.The fatty acid in grape seeds was extracted with a mixed solvent. The esterfied sample was determined by GC-MS. 42 kinds of fatty acid were separated and identified. The chief components of the fatty acid in grape seeds are unsaturable fatty acid（73. 28%）, linoleic acid（62. 38%）.
