摘要： 为了探讨云南不同茶区茶树种质资源的红碎茶香气成分特征物质及种质间香气组成的差异，采用GC/MS方法，对保存于国家种质大叶茶树资源圃内云南省11个县共16份茶树种质资源的红碎茶香气成分进行了比较分析。结果表明：构成云南红碎茶香气特征性物质主要是芳樟醇、(E)－2－己烯醛、苯乙醛、香叶醇、反式氧化芳樟醇、雪松醇、水杨酸甲酯、顺式氧化芳樟醇、正己醛、橙花叔醇。香气指数（FI）聚类分析，可把16份种质的红碎茶香型划分为三种类型：（１）高芳樟醇及其氧化物含量类型；（２）高芳樟醇及香叶醇含量类型；（３）高(E)-2-已烯醛含量型。 萜烯指数（TI）分析表明，保山市和临沧市的红碎茶香气特征较为接近，西双版纳州、德宏州、普洱市的红碎茶香气特征较为接近。综上，云南不同茶区茶树种质资源的红碎茶香气存在地方风格，红碎茶香气地方风格的存在与各地栽培的地方品种资源不同有关。

Abstract: In the purpose of clarifying the aroma material base different of broken black tea from different areas in Yunnan, aromatic components of 16 tea resources from 11 counties in Yunnan Province was conducted by GC/MS. The results showed that major aromatic components of broken black tea were linalool, (E)-2-hexena, phenylacetaldehyde, geraniol, linalool oxide trans-furanoid, cedrol, methylsaicylate, linalool oxide cis-furanoid, n-hexanal and nerolidol. The aromatic flavor of 16 broken black teas were divided three groups by dendrograms of cluster analysis based on flavor index (FI): (1) high content of linalool and linalool oxide. (2) High content of linalool. (3) High content of (E)-2-hexena. Otherwise, the result of analysis of terpene index (TI) indicated the aroma flavor of broken black teas from Baoshan and Lincang were alike, and those from Xishuangbanna, Dehong and Pu’er were similar. In a word, the aroma flavor of black broken teas from different tea areas in Yunnan were various, which were related to the characteristics of located varieties.
