摘 要：
[目的]比较青刺果油不同提取方法的差异。[方法]应用超临界CO_2萃取法(SCFE)、超声法和压榨法提取青刺果油,从得油率、感官品质和理化指标等方面进行对比,并通过气相色谱-质谱(GC-MS)法测定3种方法所得油脂的成分与含量。[结果]SCFE法、超声法和压榨法的得油率分别为31.9%、32.5%、28.2%;所得油脂中主要脂肪酸成分相同,均为油酸、亚油酸、棕榈酸和硬脂酸,饱和脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸比例分别为1.00∶1.58∶1.47、1.00∶1.75∶1.63、1.00∶1.67∶1.52。[结论]超临界CO_2萃取法提取的青刺果油更可行。

摘 要：
[Objective] The study was to compare the different extraction method of seed oil of Prinsepia utilis. [Method] Seed oil of Prinsepia utilis was extracted by different methods including supercritical CO2extraction( SCFE),organic solvent-ultrasonic and traditional squeezing method. The chemical components of the seed oil were analyzed by GC-MS. By the same,the yield,sensory quality and chemical indicators were studied in comparison. [Result]The yield of seed oil of Prinsepia utilis extracted by SCFE is 31. 9%,lower than that by organic solvent-ultrasonic extraction( 32. 5%),both higher than that by traditional squeezing method( 28. 2%). There are the same 4 main fatty acids in seed oil of Prinsepia utilis made by the three methods,including oleic acid,linolic acid,palmitic acid,stearic acid. The proportion of saturated to monounsaturated to polysaturated fatty acids of the oil by SCFE was 1. 00∶ 1. 58∶ 1. 47,the other two ways were 1. 00∶ 1. 75∶ 1. 63 and1. 00∶ 1. 67∶ 1. 52. [Conclusion] It was more feasible to extract the seed oil of Prinsepia utilis with supercritical CO2 extraction method.
