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
