摘  要:采用同时蒸馏萃取法(SDE)提取火麻仁精油,精油得率为0.096%,然后经气相色谱-质谱联用技术对火麻仁精油成分进行分离鉴定。分离出128种成分,鉴定出95种挥发性成分,占火麻仁精油总成分的90.88%。其中主要成分为α-石竹烯(7.59%)、十五烷酸(5.74%)、4-羟基-2-苯乙酮(5.45%)、a,a,4-三甲基苯甲醇(5.38%)、萘及其衍生化合物(5.22%)、呋喃酮(3.49%)、1-甲氧基-4-(1-丙烯)-苯(3.71%)、石竹烯氧化物(3.59%)、D-柠檬烯(3.16%)、苯乙醛(3.03%)、3-甲氧基丙二醇(2.97%)、苯酚类(2.85%)、葎草烯(2.56%)、环己烯醇(2.14%)、吲哚(1.64%)、1,3,3-三甲基环庚烷醇(1.41%)、己醛(1.18%)、8-甲基-1-十一碳烯(1.15%)、十四烷烃(1.07%)、柠檬醛(1.02%)。Hemp seed oil was extracted by simultaneous distillation and solvent extraction (SDE).The yield of oil was 0.096%.The oil was subjected to gas chromatography-mass spectrometric analysis (GC-MS).A total of 128 components were well separated,of which 95 were identified,altogether accounting for 90.88% of the total components.The main compounds identified and their relative contents were as follows: α -caryophyllene (7.59%),pentadecanoic acid (5.74%),4-hydroxy2-methylacetophenone (5.45%),a,a,4-trimethyl-benzenemethanol (5.38%),naphthalene and derivative (5.22%),2(3H)-furanone (3.49%),1-methoxy-4-(1-propenyl)-benzene (3.71%),caryophyllene oxide (3.59%),D-limonene (3.16%),benzeneacetaldehyde (3.03%),3-methoxy-1,2-propanediol (2.97%),phenol (2.85%),humulene (2.56%),2-cyclohexen-1-ol (2.14%),indole (1.64%),1,3,3-trimethyl-bicycloheptan-2-ol (1.41%),hexanal (1.18%),8-methyl-1undecene (1.15%),tetradecane (1.07%) and citral (1.02%).
