摘要:

采用水蒸气蒸馏的方法提取牛至精油,以气相色谱- 质谱联用(GC-MS)结合气相色谱- 闻香器(GC-O)的方法对牛至精油中的挥发性成分进行分离鉴定。结果从牛至精油中共分离鉴定出35 种挥发性化合物,占色谱总流出峰相对百分含量的97.50%,其中包括22 种(60.66%)烃、6 种(26.56%)酮、2 种(9.18%)酚、2 种(0.64%)酯、2 种(0.44%)醇和1 种(0.02%)醛。

Abstract:

A method based on distillation extraction followed by GC-MS coupled to GC-olfactometry was presented for the analysis of volatile compounds of essential oil from Origanum vulgare L. Thirty-five compounds were identified, accounting for 97.50% of total peak area, and consisted of 22 hydrocarbons (60.66%), 6 ketones (26.56%), 2 esters (0.64%), 2 phenols (9.18%), 2 alcohols (0.44%) and 1 aldehyde (0.02%). All these results can provide valuable and scientific information for the development and utilization of Origanum vulgare L. essential oil.

Key words: essential oil from Origanum vulagare L., GC-MS, GC-O, volatile compounds
