大花蕙兰鲜花香气成分的研究

利用气相色谱-质谱（GC/MS）分析技术对浙江栽培的大花蕙兰品种‘绿翡翠’（Cymbidium Hybrids）和‘台北小姐’（C.Miss Taipei）的鲜花进行了香气成分和含量的测定。结果表明：两种大花蕙兰香气成分的组成和含量存在明显差异,‘绿翡翠’的香气组成成分有43种,相对含量为97.13%,而‘台北小姐’有74种,相对含量为73.76%。两种大花蕙兰含有极少相同的化合物成分,相同成分4-甲基苯酚均为2个品种香气组分中含量最高的化合物,它与丙基环丙烷的总相对含量为53.97%,构成‘绿翡翠’的主要香气成分;与2-乙基丁醛和正己烷等23种化合物的总相对含量为55.15%,共同构成‘台北小姐’的主要香气成分。

Analysis of Aroma Components in Cymbidium Cultivars

The components and release amount of aroma in Cymbidium Hybrids and C.Miss Taipei was studied by gas chromatography-mass spectrometry techniques（GC/MS）.Results showed that the aroma components and contents differed between the two cultivars.There were 43 components identified in C.Hybrids,and the relative content was 97.13%.A total of 74 components were identified in C.Miss Taipei,and the relative content was 73.76%.Very few components were the same between the two cultivars.The relative content of 4-methyl-phenol was highest in the two cultivars.Both 4-methyl-phenol and propyl-cyclopropane were the major aroma components in C.Hybrids,and their relative content was 53.97%.Some 23 components,which contained 4-methyl-phenol,2-ethyl-butanal,and hexane,were the major aroma components in C.Miss Taipei,and their relative content was 55.15%.
