目的：比较名岩区和丹岩区肉桂品种茶叶品质的差异，分析造成不同岩区茶叶品质差异的化学基础。方法从生化成分和矿质元素两方面分析名岩区和丹岩区肉桂品种的鲜叶、半成品茶的差异，并对这两个地区肉桂品种半成品茶进行感官审评。结果名岩区肉桂鲜叶的内含物更为丰富，其中茶多酚和咖啡碱含量显著高于丹岩区(P<0.05)，氨基酸含量显著高于丹岩区肉桂鲜叶(P<0.05)。从矿质元素来看，名岩区原料鲜叶中的P元素和Cu元素的含量较低。制成半成品茶后，名岩区半成品茶的氨基酸总量、茶多酚、咖啡碱和水浸出物显著高于丹岩区；丹岩区半成品茶中Cu元素和Ni元素高于名岩区半成品茶；而名岩区半成品茶K、Mg元素含量较高。结论岩区的差异在生化成分和矿质元素两方面同时对肉桂品种茶叶的品质产生影响。
目的：比較名巖區和丹巖區肉桂品種茶葉品質的差異，分析造成不同巖區茶葉品質差異的化學基礎。方法從生化成分和礦質元素兩方麵分析名巖區和丹巖區肉桂品種的鮮葉、半成品茶的差異，併對這兩箇地區肉桂品種半成品茶進行感官審評。結果名巖區肉桂鮮葉的內含物更為豐富，其中茶多酚和咖啡堿含量顯著高于丹巖區(P<0.05)，氨基痠含量顯著高于丹巖區肉桂鮮葉(P<0.05)。從礦質元素來看，名巖區原料鮮葉中的P元素和Cu元素的含量較低。製成半成品茶後，名巖區半成品茶的氨基痠總量、茶多酚、咖啡堿和水浸齣物顯著高于丹巖區；丹巖區半成品茶中Cu元素和Ni元素高于名巖區半成品茶；而名巖區半成品茶K、Mg元素含量較高。結論巖區的差異在生化成分和礦質元素兩方麵同時對肉桂品種茶葉的品質產生影響。

Objective To compare the tea quality from different rock area and analyze the chemical reason of different quality.Methods Famous rock area fresh leaves, Dan rock area fresh leaves and tea semi-product were analyzed by chemical compounds and mineral elements combined with sensory analysis. Results The chemical compounds of Famous rock area fresh leaves were richer than those of Dan rock area. Tea polyphenol, caffeine and amino acids of Famous rock area were significantly higher than those of Dan rock area. To mineral elements, phosphorus and copper of Famous rock area fresh leaves were lower. After processing, amino acids and water extraction of Famous rock area were significantly higher than those of Dan rock area. Tea polyphenol and caffeine were very significantly higher than those of Dan rock area. Copper and nickel of Dan rock area were higher than those of Famous rock area. Potassium and magnesium of Famous rock area were higher.Conclusion Chemical compounds and mineral elements influenced the quality of different area rock tea at the same time.
