| 摘要: |
| 为进一步明确8804新品系果实和干红葡萄酒的香气特点,采用液-液萃取法提取8804葡萄果实和干红葡萄酒中的香气成分,应用色谱面积归一法测定各成分的相对含量。结果表明,8804葡萄果实中共鉴定出29种挥发性化合物,相对含量排在前5位的分别为邻苯二甲酸二丁酯（17.77%）、邻苯二甲酸二异辛酯（8.25%）、2-呋喃甲醛（7.10%）、2,6-二甲基-3,7-辛二烯-2,6-二醇（5.53%）、油酸（4.50%）;干红葡萄酒中共鉴定出31种挥发性化合物,相对含量排在前5位的分别为苯乙醇（26.78%）、2-甲基-四氢噻吩（12.04%）、辛酸乙酯（7.02%）、1,3-丁二醇（5.20%）、己酸乙酯（4.55%）。 |

| Abstract: |
| Aroma components in 8804 fruit and dry red wine were extracted by solvent extraction and analyzed by GC/MS.Their relative contents were determined by area normalization.Results showed 29 kinds of aroma components were identified in the grape.According to the relative content,the first five components were dibutyl phthalate(17.77%);1,2-Benzenedicarboxylic acid.diisooctyl ester(8.25%);2-furaldehyde(7.10%);3,7-Octadiene-2,6-diol,2,6-dimethyl-.(5.53%) and oleic acid(4.50%),respectively;31 kinds of aroma components were identified in the dry red wine,and the first five components of wine were Phenylethyl Alcohol(26.78%);Thiophene,tetrahydro-2-methyl-(12.04%);Octanoic acid,ethyl ester(7.02%);1,3-Butanediol(5.20%);Hexanoic acid,ethyl ester(4.55%),respectively. |
