摘要: 确定华山松籽仁中的脂肪酸组成及δ5型不饱和脂肪酸。利用岛津GC-2010气相色谱仪、DB-WAX毛细管色谱柱、37种脂肪酸甲酯混合标准品并结合等效链长(equivalent chain length,ECL)法进行分析。结果表明,华山松籽仁含有丰富的不饱和脂肪酸(达92.83%),主要为亚油酸(46.12%)和油酸(22.68%),δ5型不饱和脂肪酸含量较高,达21.70%,主要为松油酸(16.11%)。使用ECL方法可有效确定松科植物种子油脂中的δ5型不饱和脂肪酸。

Abstract: Shimadzu 2010 gas chromatograph equipped with DB-WAX capillary column, 37 fatty acid standards and the equivalent chain length (ECL) method were used to identify the fatty acid composition and δ5-unsaturated fatty acids in Pinus armandii kernel. The results indicated that Pinus armandii kernel abundantly contained unsaturated fatty acid (92.83%), mainly linoleic acid (46.12%) and oleic acid (22.68%). Moreover, large amounts of δ5-unsaturated fatty acids were also contained, mainly pinolenic acid (16.11%). The ECL method was found to enable effective identification of δ5-unsaturated fatty acids in Pinus armandii kernel.

Key words: Pinus armandii, pine kernel, δ5-unsaturated fatty acid, equivalent chain length (ECL), gas chromatography
