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

摘要

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％)、仅-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.
