摘要： 采用SDE蒸馏萃取方法提取信阳毛尖茶叶的挥发性成分，用气质联用仪及SE-54和强极性BPX70毛细色谱管柱进行分离分析比较，中等极性SE-54毛细色谱管柱分离效果较好，春茶挥发性成分中共分离并鉴定出47个峰；夏茶挥发性成分中共分离并鉴定出64个峰。对比夏茶与春茶在香气成分上的差异，综合评价春茶的香气品质优于夏茶。

Abstract: By extracting the volatile components of Xinyang MaoJian tea with the method of SDE (Simultaneous Distillation and Extraction), analyzing the extracted tea oil by two different polar capillary columns SE-54 and BPX70 with GC-MS. It is found out that the effect of the semi polar capillary column SE-54 is better than high polar column BPX70. With SE-54, 45 aroma constituents of spring tea and 63 aroma constituents of summer tea were analyzed and identified. By comparing the difference between the spring tea and summer tea aroma constituents, it is found out that the aroma quality of the spring tea is much better than that of the summer tea.
