摘　　要：采用亚临界丁烷萃取技术提取海桐籽油,并在理化性质、脂肪酸组成和热稳定性方面与传统索氏提取法进行对比。结果表明,除酸值和芥酸含量外,海桐籽油的其他理化性质均符合国家食用油标准,两种方法所得海桐籽油在脂肪酸组成及含量方面存在一定差异,但均富含不饱和脂肪酸(87.06%~88.46%);海桐籽油的芥酸含量高达23.282%~37.585%,可用于多种化工产品的制备,也可通过技术手段降低其酸值和芥酸含量后,开发为食用油新资源。此外,海桐籽油还具有较好的热稳定性。Oil was extracted from the seed of Pittosporum tobira by subcritical butane extraction and compared with traditional Soxhlet extraction in physicochemical properties, fatty acid composition and thermal stability. The results showed that in addition to the acid value and the erucic acid content, other physical and chemical properties of the oils met the national edible oil standard. The fatty acid composition and content of oils obtained by both methods had slightly different. However, they were all rich in unsaturated fatty acids(87.06%-88.46%). The erucic acid content of Pittosporum tobira seed oil was as high as 23.282%-37.585%, which could be used for the preparation of various chemical products, and could also be developed into a new edible oil resource after reducing its acid value and erucic acid content by technical means. Pittosporum tobira oil also had strong thermal stability.
