摘要
为了比较上海白玉兰花香和白玉兰鲜花精油的成分差异,采用顶空气质联用技术(HS-GC-MS)或气相色谱-质谱联用技术(GC-MS)进行挥发性成分的分析。结果表明,从白玉兰花香和白玉兰鲜花精油中共鉴定出44种成分,相同成分10种;白玉兰花香中共检测出26种成分,相对含量占其总量的96.29%,其主要成分为桉叶油醇(26.73%)、桧烯(23.29%)、β-蒎烯(18.77%)、β-月桂烯(12.22%)和α-蒎烯(6.83%);白玉兰鲜花精油中共检测出28种化学成分,相对含量占其总量的79.46%,主要成分包括苯乙醇(35.48%)、桉叶油醇(10.09%)、α-松油醇(9.12%)、柳杉二醇(5.69%)和4-松油醇(5.52%)。白玉兰花香和白玉兰鲜花精油成分在类别及相对含量上均有所差异,这为白玉兰资源的合理开发利用提供了理论依据。
To assess the differences in composition between the fragrance of Shanghai Yulania denudate fresh flowers and the essential oil extracted from fresh Y.denudate flowers,volatile constituents were analyzed by using headspace gas chromatography-mass spectrometry(HS-GC-MS)or gas chromatography-mass spectrometry(GC-MS).The results revealed a total of 44 identified compounds from both fragrance and essential oil,with 10 compounds common to both.The fragrance exhibited 26 components,accounting for 96.29%of the total,characterized predominantly by eucalyptol(26.73%),sabinen(23.29%),β-pinene(18.77%),β-myrcene(12.22%)andα-pinene(6.83%).The fresh flower essential oil contained 28 chemical constituents,comprising 79.46%of the total,with major components including phenylethanol(35.48%),eucalyptol(10.09%),α-terpineol(9.12%),cryptomeridiol(5.69%)and 4-terpineol(5.52%).Differences in the composition and relative proportions of components between the fragrance and essential oil of Y.denudate provide a scientific basis for the rational exploitation of this resource.
