Objective: To develop an identification method with significant specificity for patchouli oil.
Method: The fingerprint was performed by gas chromatography with patchouli alcohol and pogostone as chemical markers.
Result: The similarity of 12 samples were higher than 0.9 and it can be used to identify the characteristics of patchouli oil.
Conclusion: The GC fingerprint can be used for identification of patchouli oil.
