目的:研究吴茱萸挥发油的化学成分,为吴茱萸的开发利用提供科学依据。方法:固相微萃取法提取挥发油,气相色谱-质谱联用技术对挥发油成分进行分离鉴定,并采用面积归一化法确定各成分的相对质量分数。结果:共鉴定出97个成分,相对质量分数和为96.80%,其中相对质量分数较高的有β-香叶烯(24.16%)、β-水芹烯(18.77%)、(Z)-罗勒烯(14.35%)。结论:吴茱萸挥发油具有丰富的化学成分,固相微萃取-气相色谱-质谱联用能全面快速地获得其组成信息,可应用于吴茱萸挥发油成分的快速分析。
Objective: To study the chemical constituents of volatile oil from Evodia rutaecarpa, providing a scientific basis for the development and utilization of Evodia rutaecarpa. Methods: The volatile oil was extracted by solid phase microextraction and the volatile oil components were identified by gas chromatography-mass spectrometry. The relative mass fraction of each component was determined by area normalization. Results: A total of 97 components were identified with the relative mass fraction of 96.80%. Among them, β-myceliye (24.16%), β-phellandrene (18.77%), Ene (14.35%). Conclusion: The volatile oil of Evodia rutaecarpa has abundant chemical components, and the solid phase microextraction-gas chromatography-mass spectrometry can acquire its composition information quickly and comprehensively, which can be applied to the rapid analysis of the essential oil components of Evodia.
