同时蒸馏萃取/气相色谱-质谱法分析火麻仁精油成分

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%)。

Chemical Composition Analysis of the Essential Oil of Hemp Seeds by Simultaneous Distillation and Solvent Extraction Coupled with GC-MS

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-hydroxy-2-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-1- undecene (1.15%), tetradecane (1.07%) and citral (1.02%).
