摘要: 采用质子传递反应-飞行时间质谱仪(Proton Transfer Reaction-Time of Flight-Mass Spectrometry,PTR-TOF-MS)与气相色谱-质谱联用技术(Gas Chromatography-Mass Spectrometer,GC-MS)对不同品种武夷岩茶(水仙、肉桂)香气成分进行分析,结果表明:武夷水仙以反式橙花叔醇、(E,E)-2,4-庚二烯醛、芳樟醇及其氧化物等为主;武夷肉桂是反式橙花叔醇、α-法尼烯、苯甲醛为主,且在武夷山肉桂中存在高浓度的m/z 207、223、281、291几个未知化合物。2 种分析技术所检测到的香气成分和相对含量比例差异显著,两者各有优劣,相互补充,联合分析更加完整,更有利于准确地进行香气分析,同时发现PTR-TOF-MS法更能真实地反映茶叶香气的完整信息。

Abstract: The volatile compositions of two different cultivated varieties of Wuyi Rock Tea,which named Wuyi Rougui and Wuyi Shuixian,were analysised by proton transfer teaction-time of flight-mass spectrometry (PTR-TOF-MS ) and gas chromatography-mass spectrometry (GC-MS).The results show that,the volatile compositons of WuyiShuixian were mainly trans-nerolidol,(E,E) -2,4-heptadienal,linalool and its oxide,while there were trans-nerolidol,α-farnesene,benzaldehyde and its relative content in WuyiRougui.Meanwhile the concentration of m/z 207,223,281,291 were high in WuyiRougui.The compositions of volatile compounds detected in Wuyi Rock tea were great different by appling different analysis methods.It also indicated that the combination analysis was needed to provide a more complete and accurate results of the aroma.PTR-TOF-MS could be a good method to determine the aroma of tea leaves.

Key words: Wuyi rock tea, proton transfer reaction-time of flight-mass spectrometry(PTR-TOF-MS ), gas chromatography-mass spectrometry (GC-MS), aroma components
