目的优化番荔枝子油的提取工艺。方法采用渗漉法、索式提取法、超声波萃取法和超临界CO2萃取法提取番荔枝子油,以番荔枝种子的出油率为指标,确定最佳提取方法;对最佳提取方法进行工艺的优化,并采用GC-MS法分析其化学成分。结果索氏提取法提取的番荔枝子油得率最高;索式提取法提取番荔枝子油的最佳工艺为:采用石油醚为提取溶剂,提取温度为80℃,回流时间为90min,番荔枝子油的出油率为(22.28±0.21)%。GC-MS分析结果表明,最佳工艺所得的番荔枝子油的主要成分及相对含量为:棕榈酸(9.92%)、亚油酸(20.49%)、油酸(56.50%)及硬脂酸(9.14%)。结论该实验优选出的索氏提取工艺稳定,番荔枝子油中不饱和脂肪酸的含量较高,具有一定的经济应用价值。
Objective To optimize the extraction process of Annona. Methods Perfume litchi oil was extracted by percolation method, soxhlet method, ultrasonic extraction method and supercritical CO2 extraction method, and the optimum extraction method was determined by taking the oil yield of litchi litchi seeds as an index; Of the optimization, and the use of GC-MS analysis of its chemical composition. Results Soxhlet extraction was the most effective method for the extraction of Annona blossoms. The optimum extraction technology of Sorbus aucuparia L. by Sorbar extraction was as follows: petroleum ether as extraction solvent, the extraction temperature was 80 ℃, the reflux time was 90 min, Oil out of the oil rate (22.28 ± 0.21)%. The results of GC-MS analysis showed that the main components and relative contents of the aconitum cv. Oliver oil obtained from the best technology were palmitic acid (9.92%), linoleic acid (20.49%), oleic acid (56.50%) and stearic acid 9.14%). Conclusion The Soxhlet extraction process optimized by this experiment is stable, and the content of unsaturated fatty acids in Annonae rubra oil is high, which has a certain economic value.
