| 中文摘要: |
| 研究了超声波辅助提取桂花籽核仁油的工艺。在单因素试验的基础上，以料液比、超声时间、超声温度、超声功率4个因素进行四因素三水平正交试验优化桂花籽核仁油的提取条件，并通过气相色谱-质谱（GC-MS）联用技术对桂花籽核仁油成分进行定性定量分析。结果表明：桂花籽核仁油的最佳提取条件为料液比1∶?12、超声时间30 min、超声温度40?℃和超声功率240 W，在此条件下桂花籽核仁油的得率为31.69%；从桂花籽核仁油中鉴定出7种主要成分，其中含量较高的是油酸（37.98%）、亚油酸（30.21%）、肉豆蔻酸（11.02%）、棕榈油酸（6.94%）。 |
| 英文摘要: |
| The process of ultrasound-assisted extraction of kernel oil from Osmanthus fragrans seeds was studied. On the basis of single factor experiment, ratio of material to liquid, ultrasonic time, ultrasonic temperature and ultrasonic power were selected to optimize the extraction process of kernel oil from Osmanthus fragrans seeds by four factors and three levels orthogonal experiment. The components of kernel oil of Osmanthus fragrans seeds were analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). The results showed that the optimal extraction conditions were obtained as follows: ratio of material to liquid 1∶?12, ultrasonic time 30 min, ultrasonic temperature 40?℃ and ultrasonic power 240 W. Under these conditions, the yield of kernel oil of Osmanthus fragrans seeds was 31.69%. Seven main constituents were identified from the kernel oil of Osmanthus fragrans seeds. The contents of oleic acid (37.98%), linoleic acid (30.21%), myristic acid (11.02%) and palmitoleic acid (6.94%) were higher. |
