摘要: 对不同采摘期信阳毛尖茶的香气成分、茶多酚、茶多糖、茶氨酸、咖啡碱、儿茶素类等化学成分进行研究。不同采摘期信阳毛尖茶香气成分差异较大,α-松油醇、橙花醇、香叶醇、反式橙花叔醇、植酮5种特征香气成分在春茶中含量高,仅春茶中检测出顺-己酸-3-己烯酯。3个采摘季节中,春茶中茶氨酸、茶黄素含量最高,夏茶中咖啡碱、叶绿素含量最高,夏秋茶中茶多糖含量最高,秋茶中儿茶素类总量、表没食子儿茶素没食子酸酯含量最高。为信阳毛尖夏秋茶的综合利用提供参考。

Abstract: The aroma components, tea polyphenols, tea polysaccharides, theanine,caffeine, catechins and other chemical components of Xinyang Maojian tea at different picking stages were studied. The contents of α-terpineol,2,6-Octadien-1-ol,3,7-dimethyl-, geraniol, 1,6,10-Dodecatrien-3-ol, 3,7,11-trimethyl- and phytone in spring tea were high,and only cis-hexanoate 3-hexene was detected in spring tea. The contents of α -terpineol, nerolol, geraniol, trans-nerolol and phytone were high in spring tea, and only cis-hexanoate 3-hexene was detected in spring tea. Among the three picking seasons, the contents of theanine and theafrathin in spring tea were the highest,the contents of theanine and chlorophyll in summer tea were the highest, the contents of tea polysaccharide in summer and autumn tea were the highest,and the contents of total catechins and epigallocatechin gallate in autumn tea were the highest. It provides reference for comprehensive utilization of Xinyang Maojian summer and autumn tea.

Key words: Xinyang Maojian tea, aroma components, chemical compositions, tea polyphenols, catechins
