摘　　要：以月季资源月月粉、大马士革蔷薇和百叶蔷薇为材料,采用顶空固相微萃取技术,比较分析了其盛开期花瓣和雄蕊香气成分差异。结果表明:不同材料及同一材料的花瓣和雄蕊香味物质的种类及相对含量差别明显。月月粉的主要香气物质是芳香烃、萜烯类,其中,1,3,5-三甲氧基苯是其特征香味成分;大马士革和百叶蔷薇的主要香味成分组成基本一致,花瓣主要成分是2-苯乙醇,相对含量约占69%,二者微量香气差别成分是榄香醇、甲基丁香酚、香叶酯;丁香酚在3种材料的雄蕊中均存在,且是大马士革和百叶蔷薇的主要成分,而在花瓣中不含有。此研究结果为从这些月季资源中克隆相应的关键酶基因奠定基础,同时为重要花香物质的分子调控机制提供理论依据。Aromatic components in flower samples Rosa chinensis ＇ Pallida＇, R. damascene and R. centifo- lia were determined using the methods of headspace solid-phase microextraction （HS-SPME） and gas chromatography-mass spectroscopy （GC-MS）. All sorts of volatile compounds and their relative content of petals and stamens at the opening stage were compared and analyzed, respectively. For R. chinensis ＇ Pal- lida＇, flowers mainly produce arenas and terpenes, which 1, 3, 5-trimethoxy- benzene is the characteristic aromatic component. There were the similar components between the R. damascene and R. centifolia, pet- als mainly produce alcohols, the relative content of 2-phenethyl alcohol represented was about 69% of total compounds. The different aromatic components of R. damascene and R. centifolia were elemol, methyl eu- genol and geranyl acetate. The dominant volatile compound in stamens of the three rose resources was euge- nol, but there is no eugenol in their petals. The results provided a foundation for cloning significant scentedgene and theoretical basis for molecular regular mechanism of scent compounds in roses.
