| 摘 要： | 用ＧＣ／ＭＳ法分析了丹桂与名优乌龙茶品种的香气组成。结果表明，丹桂等５个名优乌龙茶品种的主要香气成分如下：丹桂茶是橙花叔醇、α－法呢烯、香叶醇、（Ｚ）－３－己烯基苯甲酸酯、β－紫罗酮＋（Ｚ）茉莉酮；肉桂茶是橙花叔醇、α－法呢烯、吲哚、香叶醇、芳樟醇；黄旦是橙花叔醇、香叶醇、α－法呢烯、（Ｚ）－３－己烯基苯甲酸酯、β－紫罗酮＋（Ｚ）茉莉酮；铁观音是橙花叔醇、吲哚、α－法呢烯、苯甲醛、β－紫罗酮＋（Ｚ）茉莉酮；毛蟹是橙花叔醇、吲哚、α－法呢烯、苯甲醛、２－苯乙醇。丹桂与其他４个名优乌龙茶品种香气成分含量最高的都是橙花叔醇，说明橙花叔醇是构成福建乌龙茶品种最主要的香气成分。尤其是丹桂与其母本肉桂的橙花叔醇含量均很高，分别达６９％和６１％。但是，不同品种主要香气成分的含量及组成存在明显差异，由此构成了不同品种的香型特征，这与感官审评的结果基本一致。
