摘　　要：目的 :建立广藿香挥发油的特征指纹图谱 ,用于广藿香的品质控制及产地鉴别。方法 :采用GC法对高要、石牌、吴川、遂溪、雷州及海南万年产广藿香挥发油进行GC图谱的比较分析。结果 :以 11个共有峰为评价指标 ,GC分析色谱条件的精密度、稳定性、重复性良好 ;同产地、不同采收期广藿香的主成分基本相同 ,但含量有差异 ;不同产地的广藿香其各组分的含量有较大的差异。结论 :以 11个共有峰作为广藿香挥发油特有的指纹图谱 ,以广藿香酮与广藿香醇的峰面积比值作为鉴别不同产地的广藿香的指标参数 ,建立了可用于广藿香道地性鉴别及品质评价的气相色谱指纹图谱标准。Objective: To establish the characteristic fingerprint and parameter of volatile oil from Herba Pogostemonis Methods: The dffferent collecting time and county samples of Herba Pogostemonis were determined by GC Results: Accuracy, stability and repeatability of the method were good. The same region samples had good stability and main constituents were same in different collection time, but content were different The samples collected from different region were more different in constituents and content Conclusion: The 11 components in common buildup the characterisitic fingerprint of volatile oil from Herba Pogostemonis The ratiio of pogostone to patchoulic alcohol were used index parameter for quality evaluation and characteristics of producing region
