【摘要】 采用水蒸汽蒸馏法提取东阳西垣香榧的新鲜外种皮中的挥发油,总提取率为6.8%。并以气相色谱-质谱联用技术对其成分进行分析,从中分离出42个色谱峰,鉴定出了30种成分。相对含量超过l%以上的组分有11种,占总含量的90.46%,分别是柠檬烯39.38%,1R-α-蒎烯31.61%,β-水芹烯5.13%,(1S-顺)-1,2,3,5,6,8a-六氢-4,7-二甲基-1-(1-甲基乙基)-萘4.00%,大牻牛尔烯3.73%,β-蒎烯2.40%,茨烯2.11%,反-β-金合欢烯1.82%,异松油烯1.47%,可巴烯1.28%,2-异丙基-5-甲基-9-亚甲基-二环[4,4,0]-1-癸烯1.26%。其中柠檬烯和α-蒎烯含量较文献报道高,实验为东阳西垣香榧外种皮的进一步开发利用提供了科学依据。更多还原

【Abstract】 The volatile oils were extracted from the episperm of Chinese Torreya by steam distillation and the oil yielding rate was 6.8%.GC-MS method was adopted to separate and identify the chemical components.About 42 peaks have been separated and 30 compounds have beed identified.And the compounds that the relative contents were more than 1% were About 11 compounds,which accounted for 90.46%.The main components were Limonene(39.38%) and α-Pinene(31.61%).Other relative contents were β-Phellandrene(5.13%),1,2,3,5,6,8a-hexahydro-4,7-dimethyl-1-(1-methylethyl)-,(1S-cis)-Naphthalene(4.00%),Germacrene(3.73%),β-Pinene(2.40%),camphene(2.11%),Trans-β-Farnesene(1.82%),Cyclohexene(1.47%),Copaene(1.28%) and Bicyclodec-1-ene,2-isopropyl-5-methyl-9-methylene(1.26%).The experiment provided scientific basis for better development and utilization of the episperm of Chinese Torreya.更多还原
