| 中文摘要: |
| 采用超临界CO2萃取得到沙棘籽油和沙棘全果油，并采用气相色谱和超高效液相色谱-飞行时间质谱对其脂肪酸、sn-2位脂肪酸及甘三酯组成进行测定与分析。结果表明：沙棘籽油中亚油酸、亚麻酸和油酸的含量较多，分别为38.71%、25.66%和20.68%，这3种脂肪酸也是其主要的sn-2位脂肪酸，含量分别为46.46%、25.49%和23.02%；LOL（13.65%）、OLO（12.06%）和LLnO（11.23%）是沙棘籽油的主要甘三酯类型；沙棘全果油中棕榈油酸（36.86%）、棕榈酸（27.27%）和油酸（18.00%）的含量较高，主要的sn-2位脂肪酸为棕榈油酸（45.57%）和油酸（32.06%）；沙棘全果油的主要甘三酯为POPo（14.38%）、PoOPo（13.77%）和OPO（12.06%）。 |
| 英文摘要: |
| Two kinds of sea buckthorn oils were individually extracted from the sea buckthorn pulp and seed by supercritical CO2 technique. Their fatty acid, sn-2 fatty acid and triacylglycerol compositions were determined by GC and UPLC-Q-TOF/MS, respectively. The results demonstrated that linoleic acid (38.71%), linolenic acid (25.66%)and oleic acid (20.68%)were the major fatty acids in the seed oil. Meanwhile, their contents in sn-2 fatty acids were also dominant, reaching 46.46%, 2549% and 23.02%, respectively. The main triacylglycerols in the seed oil were LOL (13.65%), OLO (12.06%)and LLnO (11.23%). Palmitoleic acid (36.86%), palmitic acid (27.27%)and oleic acid (18.00%)were the predominant fatty acids in the pulp oil. Palmitoleic acid (45.57%)and oleic acid (32.06%) were the main sn-2 fatty acids, moreover, POPo (14.38%), PoOPo (13.77%)and OPO (12.06%)were the predominant triacylglycerols in the pulp oil. |
