| 摘要: |
| 利用固相微萃取和气质质谱联用技术,对吉林地区山葡萄代表品种双优、双红、左优红果实的香气成分进行了GC/MS检测分析,并结合计算机检索技术对分离化合物进行了鉴定,应用TIC峰面积归一法测定了各成分的相对含量。结果发现,双优、双红、左优红果实中分别含有45,47和48种香气物质,分别占各自所有组分总峰面积的87.93%,74.76%和95.74%;3种山葡萄主要果香成分有乙酸乙酯、己酸乙酯、橙花醇乙酸酯、乙酸苯乙酯、异丁醇、3-甲基丁醇、正己醇、2-辛醇、苯乙醇、香茅醇、里哪醇、2-辛酮和苯醛等。 |

| Abstract: |
| Chemicals constituents of the volatile compounds from the Shuangyou,Shuanghong and Zuoyou varieties of wildgrape were analyzed and compared by headspace Solid-Phase Microextraction(HS-SPME) followed by gas chromatography-mass spectrometry(GC-MS).The result showed that the relative contents of volatile compounds determined by area normalization.45,47 and 48 compounds were separately identified in Shuangyou,Shuanghong and Zuoyouhong varieties,which represented 87.93%,74.76% and 95.74% of their total peak areas,respectively.The main components were acetic acid,ethyl ester;hexanoic acid,ethyl ester;neryl acetate;acetic acid,2-phyenylethyl ester;isobutylalcohol;3-methyl-1-butanol;1-Hexanol;2-octanol;benzeneethanol;trans-gernaniol(2,6-octadien-1-ol,3,7-dimethyl-,(E)-);1,6-octadien-3-ol,3,7-dimethyl-and 2-octanone etc. |
