摘要

摘要: 比较两种提取方法对巨尾桉桉叶挥发油得率和成分的影响，为更好的研究和开发桉树资源提供依据。采用气相色谱-质谱联用技术对水蒸气蒸馏法（SD）和超临界CO2法（SFE-CO2）提取的挥发油的化学成分进行比较与分析。SD法和SFE-CO2法提取得率分别为0.61%和7.8%，各鉴定出55和29个成分，各占挥发油总量的98.18%和99.59%。SFE-CO2法所得桉叶油总量及有效成分α-蒎烯和桉油醇相对含量均高于SD法，更有利于规模化生产桉叶油。

Abstract: The aim of the study was to analyze and compare the chemical constituents of essential oils extracted from the leaves of E.grandis×E.urophylla by two kinds of methods,and to provide basis for the further research and more application of Eucalyptus resources.GC/MS was used to analyze and compare the extraction rate and chemical constituents of essential oils extracted from the leaves of E.grandis×E.urophylla by steam distillation(SD) and supercritical CO2 extraction process(SFE-CO2).By the way of SD and SFE-CO2 extraction,the extraction rate of essential oil were 0.61% and 7.8% respectively 55 constituents were identified,which accounted for about 98.18% of the total essential oil by SD.While 29 constituents were identified,which accounted for about 99.59% of the total essential oil by SFE-CO2 extraction.The contents and effective constituents(such as α~Pinene and Cineole) of essential oils by SFE-CO2 extraction were higher than that by SD.The SFE-CO2 extraction was more favorable to the industrial production.
