| 摘 要： | 采用索氏提取法提取油松籽中的油脂,得油率为42.9%;对油脂进行甲酯化处理后用气相色谱-质谱联用仪检测其中的脂肪酸组成及含量。实验结果表明,油松籽油中含有7种脂肪酸,分别为肉豆蔻酸10.38%、硬脂酸3.05%、油酸21.98%、亚油酸(13,16-十八碳二烯酸)3.53%、亚油酸(9,12-十八碳二烯酸)38.38%、亚麻酸20.06%和二十碳三烯酸2.62%,其中饱和脂肪酸含量为13%,不饱和脂肪酸含量为87%。

| Abstract: | The fatty acids in the seeds of Chinese pine were extracted by Soxhlet extraction method. The ratio of extracted oil was 42.9%. The extracted fatty acids were analyzed by gas chromatography and spectrum. The experiment showed that there were seven fatty acids in the Chinese pine seeds, mainly including tetradecanoic acid 10.38%, stearic acid 3.05%, oleic acid 21.98%, linoleic acid (13,16 -octadecadienoic acid)3.53%, linoleic acid (9,12 -octadecadienoic acid) 38.38%, linolenic acid 20.06% and eicosatrienoic acid 2.62%. The saturated fatty acids and unsaturated fatty acids were 13% and 87% in amount respectively. |
