为揭示乌龙茶新品种——春兰的香气组分,采用GC/MS法对春兰及其母本铁观音进行分析。结果表明,春兰乌龙茶的主要香气成分是橙花叔醇、香叶醇、吲哚、β-紫罗酮+(Z)茉莉酮、α-法呢烯、芳樟醇、茉莉内酯、(Z)-3-已烯酸乙烯、苯甲醛;铁观音乌龙茶的主要香气成分是橙花叔醇、吲哚、α-法呢烯、苯甲醛、β-紫罗酮+(Z)茉莉酮、香叶醇、(Z)-3-已烯酸乙烯、茉莉内酯、芳樟醇。春兰及其母本铁观音主要香气成分相同,仅含量排序有所不同,这与茶叶感官审评结果相一致。春兰与其母本铁观音的橙花叔醇含量均很高,分别达55.5%和46.80%。春兰萜烯指数值仅为铁观音的一半。由于品种间主要香气成分的含量存在差异,构成了各自品种香型的特征。
In order to reveal the aroma component of Chunlan, a new variety of Oolong tea, the analysis of Tieguanyin of Chunlan and its female parent was conducted by GC / MS. The results showed that the main aroma components of Oolong tea were nerolidol, geraniol, indole, β-ionone + (Z) jasmone, α-farnesene, linalool, jasmine lactone, ) -3-hexadecanoic acid ethylene, benzaldehyde; Tieguanyin Oolong tea’s main aroma components are nerolidol, indole, α-farnesene, benzaldehyde, β-ionone + Leaf alcohol, (Z) -3-hexadecenoate, jasmolactone, linalool. Chunlan and its mother Tieguanyin aroma components of the same, only the content of the order is different, which is consistent with the tea sensory evaluation results. Chunlan and its female parent Tieguanyin orange blossom tertiary alcohol content is very high, respectively 55.5% and 46.80%. Chunlan terpene index value is only half of Tieguanyin. Due to differences in the content of the main aroma components among the cultivars, they constitute the characteristics of the scent of the respective cultivars.
