摘要： ‘云抗10号’是目前云南省推广面积最大的无性系茶树品种。本研究旨在探明‘云抗10号’为鲜叶原料加工的红碎茶香气成分组成。采用GC-MS技术对‘云抗10号’红碎茶的香气成分进行分析。从中检测出7类42种化合物，包括醇类、醛类、酯类、碳氢化合物、酮类、酚类及杂氧化合物。相对含量较多的前10种化合物依次为：芳樟醇、水杨酸甲酯、2-已烯醛、橙花醇、α-萜品醇、3,7-二甲基-1,5,7-辛三烯-3-醇、α-乙酸松油酯、苯乙醛、2,6-双（1,1-二甲基乙基）-4-甲基苯酚、1,2,4,5-四甲基苯，这10种化合物占了检测出总量的70.41%，是构成‘云抗10号’红碎茶赋香物质的基础。‘云抗10号’红碎茶主要的特征性成分是芳樟醇、水杨酸甲酯，且含量较高，其香型表现为稍带甜香尚鲜爽的香气特征。

Abstract: ‘Yunkang No.10’, tea clone was widely popularized in Yunnan tea areas. In order to study the aromatic constituents of broken black tea from‘Yunkang No.10’, aromatic components were analyzed by GC/MS method. The results showed that the aroma compositions were mainly composed of 42 compounds, including alcohol, aldehyde, ketene, ester, hydrocarbon, phenol and the mixed oxide compounds. The relative contents of top 10 in aroma compounds were as follows: linalool, methylsalicylate, 2-hexenal, nerol,α-Terpineol, 3,7-dimethyl-1,5,7-octatriene-3-ol,α-terpinyl acetate, hyacinthin, 2,6-bis (1,1-dimethyl-ethyl)-4-methyl-phenol, 1,2,4,5-tetramethyl Benzene, which occupied 70.41% of the total content of aroma compounds. The contents of Linalool and methylsalicylate were high, which were characteristic components of broken black tea from‘Yunkang No.10’. Meanwhile, the results of sensory quality indicated the flavor feature of broken black tea from‘Yunkang No.10’was light mellow and brisk.
