不同地域黄枝香乌龙茶的香气化学组成

The Aroma Constituents of Well Known Huangzhixiang Tea in Different Areas

用气相色谱／质谱联用法分析了高香型乌龙茶凤凰单枞—黄枝香在不同地域的香气化学组成．结果表明，不同地域样品香气化合物在检测的种数上差异不大，但类别及含量则有明显差异．黄枝香从山地引种于平地种植后，在其香气化合物中未能检测到乌龙茶的主要赋香成分——吲哚和茉莉酮，此外，橙花叔醇亦只有痕量检出，初步认为凤凰名枞—黄枝香存在着明显的地域香．

The aroma constituents of the Oolong Fenghuang Dancong-Huangzhixiang planted in different areas were analyzed by GC/MS. The results showed that in different areas the numbers of aroma constituents are not great different. But the aroma constituents and quantities are obviously different. Especially in the samples of Yingde and Luoding there are no the aroma compound of indol and cis Jasmaone which are the chief compounds for the aroma of Oolong tea. The preliminary studies showed that the aroma constituents of Fenghuang well known names Huangzhixinag are obviously different when it is planted in different areas.
