采用顶空固相微萃取技术（HS-SPME）提取贵州开阳富硒茶中挥发性香气成分，并结合气相色谱-质谱联用法（GC-MS）进行分析，研究固相微萃取头的种类、温度、吸附和解吸附时间等条件对香气物质的影响。研究结果表明：采用DVB/CAR/PDMS复合型固相微萃取头，于80℃下顶空萃取1 h吸附效果最佳；所吸附挥发性香气物质经GC-MS分析，共鉴定出种香气成分57种，其中醇类14种（相对含量29.62%），醛类9种（相对含量22.53%），烷烃14种（相对含量11.07%），酮类9种（相对含量4.92%），酯类和烯烃含量较低。

In order to establish a method for determining the aromatic components of Kaiyang selenium-enriched tea, headspace solid phase microextraction (HS-SPME) was coupled to GC-MS. The effects of SPME fiber type, temperature and adsorption times on the kinds and amounts of aromatic components of tea were evaluated. The optimal SPME extraction temperature and time were 80 ℃ and 60 min using DVB-CAR-PDMS fiber for adsorption, respectively. The result showed that more than 57 aromatic components were identified including 14 alcohols (29.62%), 9 aldehydes (22.53%), 14 hydrocarbons (11.07%) and 9 ketones (4.92%), but those of esters and alkenes compounds were both lower.
