摘要
目的:测定广西境内5个不同产地的生姜挥发油的化学成分。方法:采用水蒸气蒸馏法提取挥发油,并用气相色谱-质谱(GC-MS)联用法对广西生姜挥发油化学成分进行分析。结果:广西5个产地的生姜挥发油得油率在0.11%～0.23%之间。5个产地的生姜挥发油中共有化学成分21个,相对百分含量在60%～85%之间。共有化学成分主要有1S-α-蒎烯(1S-α-Pinene)、莰烯(Camphene)、桉油精(Cineole)、龙脑(Borneol)、橙花醇(Nerol)和柠檬醛(Citral)。不同产地的生姜挥发油中,同一成分相对百分含量差异较大,其中橙花醇的相对百分含量相差近10倍。结论:广西境内不同产地的生姜挥发油的化学成分差异不大,但同一成分的相对百分含量差异较大。
OBJECTIVE： To determine the chemical components of volatile oils of Zingiber officinale from different habitats in Guangxi. METHODS： The volatile oils were extracted by water distillation method and the chemical component was analyzed by GC-MS. RESULTS： The yield rate of volatile oils were 0.11%-0.23%. Twenty-one common components were present in volatile oils from Z. officinale from five habitats in Guangxi, while the relative percentage content was between 60%-85%. The chemical components including 1S-α-Pinene, Camphene, Cineole, Borneol, Nerol and Citral were found in Z. officinale. There was significant difference in relative percentage of same components, particularly the highest percentage of nerol was 10 times as munch as the lowest. CONCLUSION： The chemical components of volatile oils in Z. officinale from different habitats in Guangxi have little difference, but there is great difference in the same chemical components.
