白木香种子油脂肪酸组成分析

[目的]为白木香种子的综合开发利用提供科学依据。[方法]对20 g白木香种子采用索氏提取法测定种子油含量,采用GC-MS法对种子油的脂肪酸成分进行分析。[结果]白木香种子油含量为68.5%,远高于其他木本植物的种子。白木香种子油中含有7种脂肪酸,其中油酸的含量最高,占62.75%,硬脂酸次之,占15.92%,再次为棕榈酸,占14.52%。油酸和硬脂酸分别是含量最高的不饱和脂肪酸和饱和脂肪酸。总不饱和脂肪酸占脂肪酸含量的68.52%,饱和脂肪酸占31.48%。SFA∶MUFA∶PUFA为1.00∶2.04∶0.13。[结论]白木香种子含油量极高,且具有重要的营养价值,可为我国的生物质燃料油工业提供丰富的可再生原料。

Analysis on the Fatty Acid Composition in Aquilaria sinensis Seed Oil

[Objective] The study aimed to supply scientific foundation for the synthetic exploitation of Aquilaria sinensis seeds.[Method] The oil content in 20 g A.sinensis seeds was determined by soxhlet extraction and GC-MS method was used to analyze the fatty acid components in seed oil.[Result] The oil content in A.sinensis seeds was 68.5% and far higher than that in seeds of the other woody plants.The oil in A.sinensis seeds contained 7 fatty acids,in which the content of oleic acid was highest,accounting for 62.75%,the second was stearic acid,accounting for 15.92% and the third was palmitic acid,accounting for 14.52%.Oleic acid and stearic acid were unsaturated and saturated fatty acids with highest contents resp.The total unsaturated fatty acid accounted for 68.52% of fatty acid content and the saturated fatty acid accounted for 31.48%.The ratio of SFA to MUFA to PUFA was 1.00∶2.04∶0.13.[Conclusion] The A.sinensis seeds had great high oil content and important nutrient value,could provide abundant renewable raw materials for the fuel oil industry of raw matter in China.
