摘　　要：目的分析广藿香挥发油的傅里叶变换红外光谱及所含的化学成分。方法采用傅里叶变换红外光谱法和气相色谱-质谱法测定样品挥发油的指纹图谱和化学成分,用色谱峰面积归一法计算各化学成分的相对百分含量。结果从4批广藿香饮片挥发油中共鉴定出20种化学成分,占挥发油总量的90.6%～96.0%。其中特征成分均为广藿香醇（19.6%～46.2%）、广藿香酮（5.2%～27.5%）、α-愈创木烯（3.8%～6.7%）、δ-愈创木烯（4.8%～8.3%）、α-广藿香烯（3.8%～4.3%）、β-广藿香烯（4.5%～14.8%）、刺蕊草烯（4.1%～5.0%）、β-丁香烯（4.3%～5.0%）等。结论上述方法简单,迅速,准确,可用于市售广藿香的质量控制。Objective To analyze through infrared spectroscopy the chemical components of the essential oils in processed Pogostemonis Herba. Methods The fingerprints and constituents of the essential oils from 4 samples were analyzed by FTIR and GC-MS. The relative content of each component was determined by area normalization. Results The compounds of 20 kinds were all identified from the volatile oils of 4 samples,which accounted for 92.7%-94.3% of the total volatile oils. The characteristic compounds of the volatile oils are patchouli alcohol （19.6%-46.2%）,pogostone （5.2%-27.5%）,α-guaiene （3.8%-6.7%）,δ-guaiene（4.0%-8.3%）, α-patchoulene（3.8%-4.3%）,β-patchoulene（4.5%-14.8%）,seychellene（4.1%-5.0%）,β-caryophyllene（4.2%-5.0%）,etc. Conclusion This method is simple, rapid and accurate for the quality control.
