Abstract

The main odorant constituents of Cedrus atlantica essential oil were characterized by GC-Olfactometry (GC-O), using the Aroma Extract Dilution Analysis (AEDA) methodology with 12 panelists. The two most potent odor-active constituents were vestitenone and 4-acetyl-1-methylcyclohexene. The identification of the odorants was realized by a detailed fractionation of the essential oil by liquid-liquid basic extraction, distillation and column chromatography, followed by the GC-MS and GC-O analyses of some fractions, and the synthesis of some non-commercial reference constituents.

摘要

采用香气提取物稀释分析（AEDA）方法，让12名小组成员参与，通过气相色谱-嗅觉测量法（GC-O）对大西洋雪松精油的主要气味成分进行了表征。两种气味活性最强的成分是扁柏酮和4-乙酰基-1-甲基环己烯。通过液-液碱性萃取、蒸馏和柱色谱对精油进行详细分离，随后对部分馏分进行GC-MS和GC-O分析，并合成一些非商业参考成分，从而实现了对气味成分的鉴定。
