GC-MS analysis of aroma components extracted from sweet potato leaf tea by microwave-simultaneous distillation and extraction

  • 摘要: 采用微波-同时蒸馏法提取红薯叶茶的香精油,然后经气相色谱-质谱联用技术对香气成分进行分离鉴定,共鉴定出97种成分,占红薯叶茶香气成分总峰面积的83.95%。其中主要香气成分为α-荜澄茄烯醇(1.07%)、1,2,3,4,4α,7-六氢化-1,6-二甲基-4-(1-甲基乙基)萘(1.22%)、(1S-cis)-1,2,3,5,6,8α-六氢化-4,7-二甲基-1-(1-甲基乙基)萘(1.32%)、2,6-二甲基-6-(4-甲基-3-戊烯基)-双环3.1.1庚-2-烯(1.37%)、γ-榄香烯(1.38%)、叶绿醇(1.65%)、石竹烯氧化物(2.07%)、8-异丙基-1,5-二甲基-环十碳-1,5-二烯(8.49%)、石竹烯(14.61%)等。鉴定的物质大多数为萜烯类及其衍生物,具有一定的生理活性。 

     

    Abstract: The aroma components were extracted from sweet potato leaf tea by simultaneous distillation and extraction, and analyzed by gas chromatography-mass spectrum (GC-MS) .97 kinds of components were identified, which accounted for 83.95% of the total peak area of the aroma components.Among them, the major components were αlpha-cadinol (1.07%) , 1, 2, 3, 4, 4α, 7-hexahydro-1, 6-dimethyl-4- (1-methylethyl) naphthalene (1.22%) , (1S-cis) -1, 2, 3, 5, 6, 8α-hexahydro-4, 7-dimethyl-1- (1-methylethyl) naphthalene (1.32%) , 2, 6-dimethyl-6- (4-methyl-3-pentenyl) bicycle 3.1.1hept-2-ene (1.37%) , gamma-elemene (1.38%) , ptytol (1.65%) , caryophylleneoxide (2.07%) , 8-isopropenyl-1, 5-dimethyl-cyclodeca-1, 5-diene (8.49%) , caryophyllene (14.61%) , et al.Components which were identified were terpenes and derivative, its had physiological activity.
