【摘要】 以菊花品种‘神马’(Chrysanthemum moryfolium‘Shenma’)为试材,采用静态顶空和气相色谱-质谱联用技术分析菊花不同花期香气成分种类及其含量的变化。结果表明:菊花在5个不同开花时期共分离鉴定出69种香气成分,主要为萜烯类、醇类、醛类和烷烃类化合物。菊花不同花期的主要香气物质及其含量均发生了变化。花蕾期检测出香气成分41种,含量较多的有p-蒎烯、1,2,5,5-四甲基-1,3-环戊二烯、环氧乙烷、1R-α-蒎烯、2,6-二甲基-3,5-庚二烯-2-醇、乙醇;初开期检测出香气成分56种,含量较多的有1,2,5,5-四甲基-1,3-环戊二烯、α-蒎烯、2,6-二甲基-3,5-庚二烯-2-醇、5-(1,1-二甲乙基)-1,3-环戊二烯、环氧乙烷、异环柠檬醛;半开期检测出香气成分46种,含量较多的有1,2,5,5-四甲基-1,3-环戊二烯、α-蒎烯、环氧乙烷、2,6-二甲基-3,5-庚二烯-2-醇、5～(1,1-二甲乙基)-1,3-环戊二烯;盛开期检测出香气成分46种,含量较多的有1,2,5,5-四甲基-1,3-环戊二烯、α-蒎烯、环氧乙烷、乙醇、2,6-二甲基-3,5-庚二烯-2-醇、5-(1,1-二甲乙基)-1,3-环戊二烯;盛开末期检测出40种香气成分,含量较多的有p-蒎烯、1,2,5,5-四甲基-1,3-环戊二烯、环氧乙烷、乙醇、2,6-二甲基-3,5-庚二烯-2-醇。更多还原

【Abstract】 The aroma constituents and contents present in cut flower chrysanthemum[Chrysanthemum morifolium(Ramat.) Kitam.’Shenma’]were analyzed during different blooming stages by means of Head Solid-phase Micro-extraction(HS-SPME) and gas chromatography-mass spectrometry(GC-MS).The results showed that 69 kinds of aroma constituents were detected at 5 different blooming stages of chrysanthemum and the main aroma constituents were terpenes,alcohols,aldehydes and alkanes.The number and contents of aroma constituents were changed during different blooming stages.Forty-one aroma constituents were identified in the flowers at flower bud stages and the major constituents included thatα-pinene,1,2,5,5-tet-ramethyl -1,3-cyclopentadiene,oxacyclopropane,1R-α-pinene,2,6-dimethyl-3,5-heptadi en-2-ol,ethanol.Fifty-six constituents were identified in the flowers at early opening stages and the major constituents included that 1,2,5,5-tetramethyl-1,3-cyclopentadiene,α-pinene,2,6-dimethyl-3,5-heptadien-2-ol,5-(1,1-dimethy lethyl)-1,3-cyclopentadiene,oxacyclopropane, isocyclocitral.Forty-six aroma constituents were identified in the flowers at half opening stages,and 1,2,5,5-tetramethyl-1,3-cyclopentadiene,α-pinene,oxacyclopropane,2,6-dimethyl-3,5-heptadien-2-ol,5-(1,1-dimethy lethyl)-1,3-cyclopentadiene were the major constituents.Forty-six aroma constituents were identified in the flowers at full opening stages,and 1,2,5,5-tet-ramethyl -1,3-cyclopentadiene,α-pinene,oxacyclopropane,ethanol,2,6-dimethyl-3,5-heptadien-2-ol,5-(1,1-dimethyleth-yl) -1,3-cyclopentadiene were the major constituents.Forty aroma constituents were identified in the flowers at end of full opening stages,andα-pinene,1,2,5,5-tetramethyl-1,3-cyclopentadiene,oxacyclopropane,ethanol,2,6-dimethyl-3,5-heptadien -2-ol were the major constituents.更多还原
