GC-MS法检测广藿香挥发油的化学成分

摘要 目的] 建立广藿香挥发油的指纹图谱检测方法，对广藿香的品质进行控制。方法] 采用GC-MS法对广藿香挥发油成分进行定性和量化分析，并对市售的不同批次样品进行检测。结果] 以9个共有峰为评价指标，实验的重复性、稳定性、重现性良好；不同批次的样品各组分的含量有显著差异。结论] 以9个共有峰作为广藿香挥发油的指纹图谱，以广藿香酮与广藿香醇的峰面积比值作为控制质量的指标参数，建立了相应的指纹图谱。建议在使用广藿香时应根据产品的不同特点建立相应的指纹图谱质量标准。

Detection of Essential Oils from Pogostemon Cablin by GC-MS

Abstract Objective] To set up the method of detecting the essential oils from Pogostemon cablin and establish the quantitative determination on Pogostemon cablin content. Method] The essential oil was analyzed quantitatively and qualitatively on GC-MS instrument. For controlling the quality, GC fingerprint of Pogostemon cablin was set up by using GC-MS. Result] Nine compounds including patchouli alcohol and pogostone were identified among 19 main peaks in three samples sold in the market.Conclusion] The fingerprint can help distinguish the quality and assess the differences of Pogostemon cablin in various areas in China.
