目的:建立马尾松挥发油的气相色谱指纹图谱,并对不同产地的马尾松针挥发油成分进行比较。方法:采用GC法,以石竹烯为参照物,对10批全国不同产地马尾松针挥发油的指纹图谱进行研究。结果:GC指纹图谱中共有17个共有峰,共有峰面积之和超过总峰面积69%,不同产地马尾松针挥发油的主要成分相似,但含量差异较大。结论:建立的指纹图谱能够为马尾松药材及其制剂的质量控制提供依据。
OBJECTIVE: To establish gas chromatographic fingerprint of the volatile oil of Masson pine and to compare the volatile oil components of Pinus massoniana from different areas. Methods: The fingerprints of volatile oil of Pinus massoniana from 10 batches of different places in China were studied by GC method and caryophyllene as reference. Results: There were 17 common peaks in GC fingerprints, and the sum of the total peak areas exceeded 69% of the total peak area. The main components of the essential oil of Pinus massoniana from different areas were similar, but the contents were quite different. Conclusion: The established fingerprint can provide the basis for the quality control of Masson pine herbs and their preparations.
