火炬松挥发物的固相微萃取-气相色谱／质谱法分析

Analysis of Volatile Components of Pinus teada L.by Gas Chromatography-Mass Spectrometry with Solid-phase Microextraction

采用固相微萃取(SPME)技术,结合气相色谱/质谱(GC-MS)分析了火炬松枝条和针叶中的挥发性化合物,共鉴定了30种化学成分。其中枝条中分离鉴定出21种挥发性成分。主要成分为α-蒎烯、β-蒎烯、β-月蒎烯、反式-石竹烯、β-杜松烯、大根叶烯-D;针叶中分离鉴定出24种挥发性成分,主要成分为α-蒎烯、β-蒎烯、β-月桂烯、β-水芹烯、异长叶烯、反式-石竹烯、α-律草烯、大根叶烯-D、双环吉马烯和双环榄香烯。

Volatiles compounds from branch and needle of Pinus massoniana were extracted by solid-phase microextraction and analyzed by gas chromatography-mass spectrometry. Twenty-one and twenty-four compounds were identified in the extracts of branch and needle, respectively, the main components were founded to be α-pinene（52.05%）, β-pinene（21.82%）, β-Myrcene（15. 76%）, β-Terpinene （2.69%）, Germacrene-D （1.76%） for branch, and α-pinene（43. 81%）, β-pinene（28. 49%）, β-phellandrene（6. 72%）, trans-caryophyllene （6.65%）,β-Myrcene （4. 17%）, α-Humulene （1. 30%）, Germacrene-D （1.20%）, Bicyclogermacrene （1. 05%）, Bicycolelemene（1.01%） for needle.
