目的分析比较4种国产沉香的挥发性成分。方法采用低温-动态-微波法及气相色谱-质谱联用技术,以固相微萃取顶空进样,提取并分析比较国产沉香挥发油中的化学成分。结果从4种国产沉香样品的挥发油中分别检出58、81、54、38种化合物,依次占总峰面积的73.27%、91.98%、43.23%、33.17%。结论 4种国产沉香挥发油中以萜烯类化合物为主,但各样品的组成成分和含量差异较大。
Objective To compare and analyze the volatile components of four kinds of domestic incense. Methods Low-temperature-dynamic-microwave method and gas chromatography-mass spectrometry (GC-MS) were used to carry out headspace sampling with solid-phase microextraction. The chemical constituents of the volatile oils from Chinese medicinal plants were extracted and analyzed. Results A total of 581 compounds, 54 compounds, and 38 compounds were detected respectively from the volatile oil of four kinds of Chinese medicinal plants, accounting for 73.27%, 91.98%, 43.23% and 33.17% of the total peak area respectively. CONCLUSION: The terpene compounds of the four kinds of volatile oils from Chinese medicinal plants are mainly based on their contents, but their composition and content vary greatly.
