| 中文摘要:
| 为了探明紫娟茶的适制性,采用全自动顶空固相微萃取结合气质联用法对紫娟红茶的香气成分进行了定性定量分析,并与滇红茶的香气成分进行比较。结果从紫娟红茶中鉴定出香气成分83种,从滇红茶中鉴定出香气成分82种,它们的香气成分均以醇类化合物为主,分别占提取物总量的44.42%和44.99%;紫娟红茶的香气成分主要为芳樟醇、芳樟醇氧化物、植醇、咖啡因、6,10,14-三甲基-2-十五烷酮、十六烷酸、香叶醇等;而滇红茶的香气成分主要为芳樟醇、十六烷酸、芳樟醇氧化物、植醇、香叶醇、咖啡因、水杨酸甲酯等。研究发现,紫娟红茶和滇红茶在香气组成上较接近,共有香气成分77种;紫娟红茶除醛类、酯类和酸类含量低于滇红茶外,其余成分含量均高于滇红茶。

| In order to explore the manufacturing suitability for Zijuan tea,the aroma components of Zijuan black tea were extracted by fully automated HS-SPME,and were identified by GC-MS.Then comparison of the aromatic components and contents between Dianhong tea was made.The results showed that 83 kinds of aroma components were identified in Zijuan black tea and 82 kinds in Dianhong tea,alcohol was the major aromatic components in these two kinds of tea,representing 44.42% and 44.99% of the total peak area respectively.The major aromatic compounds of Zijuan black tea were linalool,linalool oxide,phytol,caffeine,6,10,14-trimethyl-2-pentadecanone,hexadecanoic acid and geraniol,respectively,while the major aromatic compounds of Dianhong tea were linalool,hexadecanoic acid,linalool oxide,phytol,geraniol,caffeine and methyl salicylate.The aromatic components in these two kinds of tea were found very similar and 77 of them were identical,the contents of aldehydes,esters and acids compounds in Zijuan black tea were lower than that in Dianhong tea,but the contents of other compounds are higher than Dianhong tea.
