Analysis of aromatic compounds during four flowering stages in Narcissus spp.by GC-MS
In order to study the dynamic changes of aromatic compounds during the development of European daffodil, the aromatic compounds during four flowering stages of Narcissus spp.'Dutch Master' were analyzed using headspace solid phase micro extraction (HS-SPME) and gas chromatography mass spectrometry (GC-MS) methods.The results showed that aromatic compounds and concentrations varied significantly during development of European Narcissus spp.plants.Twenty-six volatile aromatic compounds were identified during four flowering stages.Major aromatic components were terpenes, followed by alcohol compounds, including (Z)-β-ocimene, noreloprene, β-myrcene, benzene, 1,4-dimethoxy-ether, (E)-β-ocimene, eucalyptol, terpinolene, 3-carene, and linalool.The characteristic aromatic components of Narcissus spp.'Dutch Master' were (Z)-β-ocimene, β-Myrcene, and noreloprene.The release of major aromatic compounds during flowering showed a tendency to rise first and then fall, while the maximum number and highest concentration of different aromatic compounds were observed at the fully flowering stage.
