目的:利用气相色谱-质谱联用技术分析市售樟木药材的挥发性化学成分。方法:用水蒸气蒸馏的方法提取样品,气相色谱-质谱联用技术进行分析。结果:对市售7批樟木药材进行分析,共分离出172个成分,鉴定了其中5批具有代表性的样品中均含有的成分93种。结论:樟木药材挥发油提取步骤简单,对樟木药材的挥发油进行GC-MS分析可以准确的鉴别樟木药材的真伪,并通过挥发油成分的相对含量对药材质量进行评定。 Objective: To analyze the volatile chemical composition of camphor wood by gas chromatography-mass spectrometry. Methods: Samples were extracted by steam distillation and analyzed by gas chromatography - mass spectrometry. Results: Seven batches of camphor wood were collected and analyzed. A total of 172 constituents were isolated and 93 representative batches of five representative batches were identified. Conclusion: The extraction of essential oil from camphor wood is simple. The GC-MS analysis of volatile oil of camphor wood can accurately identify the authenticity of camphor wood and evaluate the quality of medicinal materials through the relative content of volatile oil components.
