| 中文摘要: |
| 研究了白木香种子油超临界CO2萃取工艺条件，并对所得种子油进行了脂肪酸组成和理化指标分析。得到的超临界CO2萃取最佳工艺条件为：物料粒度20～30目，萃取压力30 MPa，萃取温度45?℃，萃取时间80 min，分离釜Ⅰ压力11 MPa，分离釜Ⅰ温度50?℃。在最佳工艺条件下，白木香种子油平均收率为412%，与传统石油醚回流提取收率（平均收率41.9%）相近。白木香种子油脂肪酸种类较为丰富，主要组成为油酸、棕榈酸、亚油酸和硬脂酸，其中不饱和脂肪酸含量高于80%。 |
| 英文摘要: |
| The supercritical CO2 extraction process of Aquilaria sinensis (Lour.) Gilg seed oil was studied and the fatty acid composition and physicochemical indexes of the seed oil were also analyzed. The results showed that the optimal extraction conditions were obtained as follows: particle size 20-30 meshes, extraction pressure 30 MPa, extraction temperature 45?℃, extraction time 80 min, separation kettle Ⅰ pressure 11 MPa and separation kettle Ⅰ temperature 50?℃. The average yield of Aquilaria sinensis (Lour.) Gilg seed oil was 41.2% under these conditions, which was similar to 41.9% of the yield by petroleum ether extraction. The Aquilaria sinensis (Lour.) Gilg seed oil was abundant in fatty acids, in which the content of unsaturated fatty acid was higher than 80%, and the main components were oleic acid, palmitic acid, linoleic acid and stearic acid. |
