| 摘 要： | 采用顶空吸附法（HAS法）和茶汤过柱吸附法（TLA法）分析了绿茶提取液的香气，结果表明，HAS法提取的香气在感官上与茶叶香气较一致，通过GC检测，两种方法提取香精油的组分差异较大，在检测时间内相同的香气组分只有54．17％，TLA法未检测到芳樟醇的氧化物和异构产物，但检测到一些别的物质。

| Abstract: | The aroma of green tea liquid was studied by using headspace absorption method (HAS method) and tea liquid absorption method (TLA method) with XAD-2 rein. The results show that the essential oil made by HAS method has tea flavor but that made by TLA method has a little difference compared with tea flavor. There are some differences in compounds between the two; the rate of reflection is 54.17% during the same TR. Linalool oxides and its isomeric materials are not found by using TLA method, but some other materials are found. |
