| 摘 要： | 首次使用顶空固相微萃取/气象色谱-质谱联用(HS-SPME/GC-MS)技术分析了10个不同品种春茶及秋茶鲜叶中的芳香物质组分及含量。结果表明,在10个不同品种的春、秋茶鲜叶中均检测出70余种挥发性化合物,主要包含酯类、醇类、烯类、烷烃类、酮类、醛类,其中酯类及醇类为主要物质。同时对春、秋茶鲜叶中主要芳香物质成分及含量做了比较,酯类及醇类(芳樟醇)是茶鲜叶香气成分的主要来源,且春茶鲜叶中具有花香的芳香物质含量要比秋茶中的含量高。

| Abstract: | This experiment is the first time to use the headspace solid-phase microextraction(HS-SPME) and gas chromatography-mass spectrometry(GC-MS) technologies to research on the composition and contents of aromatic matters in 10 varieties of fresh tea leaves in spring and autumn.Seventy kinds of volatile compounds were identified,in which,the main matters were esters,alcohols,alkenes,alkane,ketone and aldehydes,and the esters and alcohols were the major components.Comparing the compositions between spring and autumn,esters and alcohols were found to be the main aromas in fresh tea,and the aroma contents in spring were higher than that in autumn. |
