气相色谱-飞行时间质谱法结合保留指数分析小豆蔻油挥发性成分

Analysis of Volatile Compounds by GC-TOF/MS Combined with Retention Index in Cardamon Oil

为分析比较不同产地小豆蔻油中挥发性成分,采用气相色谱-飞行时间质谱法进行挥发性成的定性分析,并通过质谱库检索,结合保留指数验证,从越南小豆蔻油和英国小豆蔻油中分别鉴定出68和33个挥发性成分。结果表明,越南产地小豆蔻油的主要成分(质量分数)为α-松油醇乙酸酯(36.01%)、1,8-桉叶素(28.04%)、乙酸芳樟酯(6.58%)、芳樟醇(5.47%)、柠檬烯(4.16%)、桧烯(2.84%)、4-松油醇(1.89%)、香叶醇(1.61%)、乙酸香叶酯(1.59%)、乙酸辛酯(1.22%)等;英国产地小豆蔻油的主要成分为1,8-桉叶素(44.91%)、α-松油醇乙酸酯(38.53%)、芳樟醇(3.29%)、柠檬烯(2.46%)、α-松油醇(1.52%)、橙花醇(1.47%)、4-松油醇(1.11%)等;两个产地的小豆蔻油中挥发性成分的组成存在一定的差异。

The volatile constituents of cardamom oil from different producing area were analyzed by gas chromatography-time-of-flight mass spectrometry（GC-TOF/MS）. With the MS library search,68 and 33 volatile constituents were confirmed by using retention index in cardamom oil from Vietnam and United Kingdom origin.According to the result,alpha-terpinyl acetate（36.01%）,1,8-cineole（28.04%）,linalyl acetate（6.58%）,linalool（5.47%）,limonene（4.16%）,sabinene（2.84%）,terpinen-4-ol（1.89%）,geraniol（1.61%）,geranyl acetate（1.59%）,octyl acetate（1.22%）were the main components in cardamon oil from Vietnam origin. 1,8-Cineole（44.91%）,alpha-terpinyl acetate（38.53%）,linalool（3.29%）,limonene（2.46%）,alpha-terpineol（1.52%）,nerol（1.47%）,terpinen-4-ol（1.11%） were the main components in cardamon oil from United Kingdom origin. There were certain differences in the kinds and content of volatile constituents from two origins.
