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。' 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.
