摘要
为开发甜茶资源,采用固相微萃取法(solid-phase microextaaction,SPME)从甜茶中提取挥发性香气成分,联合气相色谱-质谱技术(gas chromatography-mass spectrometry,GC-MS)分析。结果表明:茶样中共鉴定出73种香气成分,分别为醇类22种、酮类15种、醛类13种、烷烃类7种、杂环类6种、烯烃类6种、苯类4种、萘1种,萜烯指数为0.78,研究的甜茶主要以醇类、酮类、醛类为香气物质基础。
To develop sweet tea resources,soid-phase micriextraction(SPME)was used to extract aromatic of aromatic components in tea samples,and gas-chromatography-mass(GC-MS)spectrometry was also united to analyse tea samples.The results showed that 73 kinds of aromatic components were identified in tea samples,there were 22 kinds of alcohols,15 kinds of ketones,13 kinds of aldehydes,7 kinds of hydrocarbons,6 kinds of heterocyclic,6 kinds of olefins,4 kinds of benzene,and 1 kind of naphthalene.The terpene index was 0.78 of sweet tea.In this study,the sweet tea which was researched mainly regarded the alcohols,aldehydes and ketones as the base of amomatic components.
