HS-SPME-GC-MS测定黄花菜不同部位中挥发性成分

Analysis of volatile composition of various parts in Hemerocallis citrina Baroni by HS-SPME-GC-MS

为了测定黄花菜新型品种(金娃娃)各部位中挥发性的成分,采用顶空固相微萃取法结合气相色谱-质谱联用技术,对冷冻干燥制得的黄花菜品种(金娃娃)的不同部位(开花、花苞、根、茎、叶)干燥样品和晒干花苞样品进行挥发性成分测定。结果表明:从金娃娃六个部位中共鉴定了110种化合物,其中晒干花苞部位鉴定了60种,开花部位鉴定了38种,花苞部位鉴定了24种,根部位鉴定了37种,叶部位鉴定了26种,茎部位鉴定了24种。各部位中均有其特殊的挥发性成分,其中晒干花苞部位、根部位和开花部位挥发性成分差异较大,同时各部位也有相同的挥发性成分,其中3-呋喃甲醇(3-furanmethanol)和芳樟醇(linalool)、壬醛(nonanal)为各部位中的主要挥发性物质。

In order to identified the volatile components in various parts of new varieties of Hemerocallis citrina Baroni(jinwawa),the sundried flower and freeze-dried samples of different parts(flowering,flower bud,root,stem and leaf) of the variety of daylily were used by headspace solid-phase microextraction combined with gas chromatography-mass spectrometry(HS-SPME-GC-MS).The results showed that 110 compounds were identified from five parts of H.citrina,among which 60 compounds from the sundried flower part,38 compounds from the flowering part,24 compounds from the flower bud part,37 compounds were identified from the root part,26 compounds from the leaf part and 24 compounds from the stem part.All the parts have their special volatile components,among which the sundried flower part,root part and flowering part have great differences in volatile components,all the parts also have the same volatile components,among which 3-furanmethanol,linalool and hexanoic acid are the major components in all the parts.
