- 摘要:
- 采用活体植株动态顶空套袋-吸附采集法与ATD-GC/MS（自动热脱附-气质联用）分析技术，研究了不同开花期麝香百合“白天堂”香气变化规律。结果表明：“白天堂”百合在释香过程中香气成分的数量和含量均发生了变化。在”白天堂”初开期、半开期、盛开期和衰败期4个阶段，分别检测出 14、25、37和 12 个香气组分。随着”白天堂”花的开放，其香气成分的含量逐渐增大，在盛开期达到最大，随后逐渐降低。其主要香气成分为乙苯、邻二甲苯、1,3-二甲基苯、2-乙基-1-己醇、己醛、2,6-二甲基-1,3,5,7-辛四烯和3,7-二甲基-1,3,6-辛三烯等物质。
- Abstract:
- Aroma regular pattern of ‘White Heaven’ lily during different florescences was studied by dynamic headspace collection and ATD-GC/MS(Auto Thermal Desorber-Gas Chromatography/Mass Spectrometry) in this experiment.The results showed that the number and content of aroma components of ‘White Heaven’ lily were changed in the process of flowering.In the four stages of early opening，half-opening，blooming and decaying，14，25，37 and 12 aroma components were detected.With the flowering，the content of aroma components was gradually increased until the blooming reached the maximum，but then decreased gradually.Ethyl benzene，o-xylene，1,3-dimethylbenzene，2-ethyl-1-hexanol，hexanal，2,6-dimethyl-1,3,5,7-octatetraene and 3,7-dimethyl-1,3,6-octatriene and other substances were the main aroma components.
