Abstract:

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
