Chemical compounds of the extracts from each method were analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed the percentage yield of the extracts was 0.0167, 0.0045, 0.0342, 0.4170, 0.3510, 0.3969 and 12.2400%, respectively. The major chemical component in the essential oils from all distillation methods and both solvents was benzyl salicylate, but the extracts from cold and hot enfleurage were linalool and n-undecanoic acid, respectively. |
