不同产地马尾松针挥发油的GC—MS分析

目的：对不同产地的马尾松针挥发油成分进行分析比较,探讨不同产地样品的成分组成及含量差异。方法：采集全国5个省份的马尾松针,采用水蒸气蒸馏法提取挥发油,利用气相色谱一质谱（GC/MS）联用技术,分别对5种松针挥发油的化学成分进行分析。结果：从五地的马尾松松针挥发油中分离鉴定出多种化学成分,其中石竹烯,（Z,Z,Z）-1,5,9,9四-甲基-1,4,7环-十一碳三烯,（＋）-表双环倍半水芹烯等7种总含量超过挥发油20%的成分为共有组分。结论：不同产地马尾松针挥发油的主要化学成分较为相似,主要是单萜和倍半萜,但在含量上有较大的差别。

Comparison Analysis of Volatile Constituents of Pine Needles from Pinus Massoniana Lamb Planted in Different Area by GC- MS

Objective： The volatile constituents of pine needles from pinus massoniana lamb planted in different area were analyzed to research the constituents difference among the samples from different area.Methods： Pine needles from pinus massoniana lamb were gathered from 5 province,and the oil were extracted through steam distillation.Volatile oil were analyzed by gas—chromatography—mass spectrometry.Results： There were various compositions identified from every oil sample,and 7 oil compositions including Caryophyllene、（Z,Z,Z）-1,5,9,9-tetramethyl-1,4,7-cycloundecatriene、（＋）-Epi-bicyclosesquiphellandrene and so on were contained in total 5 samples.Conclusion：The results reveal that the essential oil compositions of pine needles from pinus massoniana lamb planted in different area were similar but the contents of some compounds different greatly.
