Abstract:

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%).
