摘要：目的:从花椒籽中提取花椒籽油,寻找最佳方法及其最优条件。方法:分别用挥发油测定法、索氏提取法和超临界萃取法提取花椒籽油。每组实验所得产品甲酯化后进行气相色谱分析。结果:挥发油测定法产量为0. 88 ,索氏提取法13. 73 ,超临界萃取法15. 52 ,其中不饱和脂肪酸含量分别达到: 4. 5 , 65. 97 , 74. 97 。结论:超临界萃取法与其他两种方法相比具有优势。其最适宜操作条件为: 30MPa, 50°C下萃取 5h。
AIM: To extract Zanthoxylum oil from the seeds of Zanthoxylum bungeanum Maxin, and find out a better extraction method and its optimized operating conditions. METHODS: Zanthoxylum oil was extracted by distillation method, solvent extraction and supercritical fluid extraction, respectively. The products gained in each experiment was analyzed by GC after it had been methyl esterified. RESULTS: The yield of Zanthoxylum oil extracted by distillation, solvent extraction and supercritical fluid extraction was 0.88 %, 13.73 % and 13.52 %, respectively, and its content of unsaturated fatty acid 4.50 %, 65.97 %, 74.97 %, respectively. CONCLUSION: Supercritical fluid extraction was the better of the three mehtods, whose optimized operating conditions consisted of 30 MPa pressure, 50 °C operating temperature and 5 h extraction time.
