摘　　要：采用固相微萃取技术和气相色谱-质谱联用(GC-MS)技术对树挂期"户太9号"葡萄果实进行挥发性香气成分的分析。结果表明:"户太9号"葡萄果实共检测到5类97种香气化合物,分别为7种醛类物质,16种酮类物质,12种酸类物质,15种醇类物质,24种酯类物质,13种烃类物质以及10种杂环化合物。随着树挂期的延长,果实香气物质的主要组成成分由醛类、酮类转化为酯类物质,最终呈现出了以酯类物质为主的热带水果的甜香,带有部分醇类物质散发出来的青香的特征。The aroma compositions in ＇Hutai No.9＇ grape fruit at hanging in the vine time were extracted by solid phase micro-extraction（SPME） and were separated and analyzed by GC-MS.The rusults showed that 97 volatile components were identified in ＇Hutai No.9＇ grape respectively,7 kinds of aldehydes,16 kinds of ketone material,12 acid material,15 kinds of alcohol kind material,24 ester kind material,and kind of hydrocarbons and 10 kinds of heterocyclic compounds.With the hanging in the vine time,the main composition of fruit aroma by aldehydes,ketone gradually translated into ester,and finally showed the tropical fruit sweet primarily with ester,with part of the green sweet characteristics sent out by alcohol.
