摘要:

选用东方美人茶和铁观音为研究对象,采用顶空-固相微萃取(HS-SPME)法富集其香气物质和GC-MS进行香气成分分析。结果表明:东方美人茶和铁观音在香气组成上存在明显差异;东方美人茶的香气成分比铁观音丰富,以醇类化合物为主,其醇类、酮类和酚类化合物含量均高于铁观音,而酯类和碳氢化合物等含量低于铁观音;东方美人茶的香气成分主要是香叶醇、2,6-二叔丁基对甲苯酚、β-芳樟醇、反式-氧化芳樟醇、芳樟醇氧化物Ⅰ、2,6-二甲基-3,7-辛二烯-2,6-二醇等;而铁观音的主要香气成分是反式-橙花叔醇、α-法呢烯、吲哚、丁酸-2-甲基-2-苯乙酯、丁酸苯乙酯等。

Abstract:

The aroma constituents of Oriental Beauty tea and Tieguanyin tea were determined by HS-SPME/GC-MS. Results showed that there are many differences in aroma constitutes between oriental-beauty tea and Tieguanyin tea. The aromatic compounds of Oriental Beauty tea are much richer than those of Tieguanyin tea, and the contents of alcohol, ketones and phenolic compounds are higher but the contents of ester and hydrocarbon compounds are lower than those of Tieguanyin tea. The major aromatic compounds of Oriental Beauty tea are geraniol, butylated hydroxytoluene, β-linalool, trans-linaloloxide, linalool oxide I, and 3,7-octadiene-2,6-diol-2,6-dimethyl, while the major aromatic compounds of Tieguanyin tea are trans-nerolidol, α-farnesene, indole, butanoic acid, 2-methyl-2-phenylethyl ester, and phenylethyl butyrate.

Key words: Oriental Beauty tea, Tieguanyin tea, HS-SPME, aromatic analysis, GC-MS analysis
