摘要
目的:系统评价不同来源广藿香油的区别与质量,为后续广藿香油的应用研究提供可靠的实验基础。方法:选择水蒸气蒸馏法和超临界萃取法制备广藿香挥发油,并采用气相色谱-火焰离子化检测器(GC-FID)和气质联用色谱仪(GC-MS)定量和定性分析两种自制挥发油和市售广藿香油的区别;并应用超高效液相色谱-质谱(UPLC-MS)技术,对3种不同来源的广藿香油进行非靶向代谢组学研究。结果:3种广藿香油的化学成分大约有15种,主要包括倍半萜类、黄酮类等各类化合物。3组的组间差异性代谢物共有184种,超临界萃取与水蒸气蒸馏提取的挥发油存在显著差异,超临界萃取与市售的水蒸气蒸馏提取的挥发油差异较小,不同批次的市售广藿香油代谢物含量无明显差异。结论:自制广藿香油的化学成分和代谢成分与市售基本一致,市售的广藿香油更稳定,为后续的药物研发和应用提供科学依据。
Objective:To systematically and comprehensively evaluate the difference and quality of patchouli oils from different sources,in order to provide a scientific and reliable experimental basis for subsequent studies on the application of patchouli oil.Methods:Steam distillation and supercritical extraction were chosen to prepare patchouli oil,gas chromatography-flame ionization detection(GCFID)and gas chromatography-mass spectrometry(GC-MS)were used to quantitatively and qualitatively analyze the differences between the two lab-made volatile oils and marketed patchouli oil.The ultra-high performance liquid chromatography-mass spectrometry(UPLC-MS)technique was also applied to perform a non-targeted metabolomics study on three different sources of patchouli oils.Results:There approximately 15 chemical components of the three patchouli oils,mainly including sesquiterpenoids and flavonoids and other compounds.There were 184 differential metabolites in three groups.There were significant difference between the supercritical and steam distillation extracted volatile oils,and less difference between the supercritical and the marketed steam distillation extracted volatile oils,and no significant difference in the metabolite content of different batches of commercially available patchouli oils.Conclusion:The chemical composition of lab-made patchouli oil is essentially the same as marketed.Marketed patchouli oil is more stable,so as to provide scientific basis for its subsequent drug development and application.
