GC-MS法分析鸡皮果叶挥发油的化学成分

Analysis on Chemical Components of the Essential Oil from the Leaves of Clausena anisum-alens(Blanco.)Merr by GC-MS

[目的]为了分析鸡皮果叶[Clausena anisum-alens(Blanco.)Merr]挥发油的化学成分。[方法]用水蒸汽蒸馏法提取鸡皮果叶挥发油,用毛细管气相色谱-质谱(GC-MS)获得其总离子流图,对各个色谱峰进行了定性,并用面积归一化法获得各化合物的相对质量分数。[结果]共鉴定了20个化合物,占总挥发油质量的99.12%。主要成分为:4-甲氧基6-(2-丙烯基)-1,3-苯并二恶唑(28.97%),(+)-4-蒈烯(24.84%),大根香叶烯B(11.41%),十六烷酸(4.82%),1,2,3-三甲氧基5-(2-丙烯基)-苯(3.84%),斯巴醇(3.19%),1-二十二碳烯(2.82%),石竹烯(2.79%),1-甲基咪唑-5-甲醛(2.75%)。[结论]揭示了鸡皮果叶的药理作用,为综合开发利用鸡皮果植物提供了科学依据。

[ Objective] The research aimed to analyze the chemical components of volatile oils from the leaves of Claraena anisum-alens （Blanco.）Men.. [ Method] the essential oil was extracted from the leaves by steam distillation and analyzed by gas chromatography-mass spectrometry （GC-MS）.The relative contents were determined by area normalization. [ Result ] Twenty compounds were identified which added up to 99,11% in the volatile oils. The major compositions were 4-Methoxy-6-（2-prepenyl）-1,3-benzodioxole（28.97% ）, （ ＋ ）-4-Carene （24.84%）, Germacrene B （ 11.41 % ）, n-Hexadeear, oic acid （4.82%）, 1,2,3-Trimethoxy-5-（2-propenyl）-benzene （3.84%）, Spathulenol （3.19%）, 1-Docosene（2.82%）, Caryophyllene（2.79%） and 1- Methylimidazole-5-carboxaldehyde （ 2.75 % ）. [ Conclusion ] The study revealed the pharmacological action of Clausena anisum-alens （ Blanco. ） Merr, and provided the basis for comprehensive development and utilization.
