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。
OBJECTIVE: To analyze and compare the volatile oil components of Pinus massoniana from different habitats, and discuss the composition and content differences of the samples from different areas. Methods: Pinus massoniana needles were collected from five provinces in China. Volatile oils were extracted by steam distillation. The chemical constituents of volatile oils from five pine needles were analyzed by gas chromatography-mass spectrometry (GC / MS). Results: A variety of chemical constituents were isolated and identified from the volatile oil of Pinus massoniana pine from five regions. Caryophyllene, (Z, Z, Z) -1,5,9,9 tetra-methyl- Eleven triene, (+) - Table Bicyclohexene and other seven kinds of total content of more than 20% of volatile oil components as a common component. CONCLUSION: The main chemical components of the volatile oil of Pinus massoniana from different areas are similar, mainly monoterpene and sesquiterpenoids, but the content is quite different.
