[目的]研究新疆沙蓬籽油的最优提取条件,并对其成分进行分析。[方法]采用超临界CO2萃取工艺,以沙蓬籽油提取率为指标,研究了萃取压力、萃取温度、萃取时间对沙蓬籽油提取率的影响,在单因素试验基础上,通过正交试验得到最佳提取条件。沙蓬籽油成分采用气质联用法(GC-MS)进行分析。[结果]新疆沙蓬籽油的最优提取条件为萃取压力30 Mpa,萃取温度40℃,萃取时间3 h。在此条件下沙蓬籽油的萃取得率为13.62%。GC-MS分析表明沙蓬籽油的主要成分为亚油酸。[结论]亚油酸是人体必需脂肪酸的一种,有助于降低血清胆固醇和抑制动脉血栓,采用超临界法萃取沙蓬籽油工艺稳定可靠,具有很高的应用价值。 展开更多

[Objective] The aim was to investigate the fatty acid and amino acid components of Agriophyllum squarrosum seeds from Xinjiang.[Method] The oil sample was extracted from kernels of A.squarrosum seeds collected from Xinjiang for measuring the components and contents of fatty acids with GC-MS;semi-micro Kjeldahl method and fractional extraction were conducted to get the proteins from the kernels and determine amino acids of the proteins.[Result] The fat content of A.squarrosum seeds was as high as up to 13.7%,among which unsaturated fatty acid and linoleic acid were the major components,accounting for more than 80% of the total fatty acids,while saturated fatty acid content was lower.The content of crude proteins was 24.37% in A.squarrosum seeds,in which globulin and albumin were the main components,accounting for more than 80% of the total proteins,while glutenin,gliadin and residue proteinswere less.Protein got from A.squarrosum seeds belonged to complete protein,contained 18 kinds of amino acids.The content of glutamic acid was the highest(18.3%),followed by arginine(9.46%),aspartate(9.27%),leucine(6.67%),phenylalanine(5.04%),serine,methionine,lysine,valine,cystine,histidine and tryptophane.In addition,A.squarrosum seed was rich in essential amino acid.[Conclusion] The paper will provide reference for comprehensive development of A.squarrosum resources from Xinjiang. 展开更多
