Fingerprint Chromatogram of the Volatile Oils from Eupatorium fortunei with Different Methods

Zeng Hong-yan

Abstract

Objective: To analyze the GC-MS fingerprint chromatogram of the volatile oils from Eupatorium fortunei with threemethods. Method: The volatile oils were obtained with supercritical CO2, microwave and stream distillation. Result: Thecompounds from the volatile oils extracted with the three methods is different. Conclusion: The volatile oil obtained withsupercritical CO2 is natural. Supercritical CO2 extraction is ideal for extracting the volatile oils, and microwave extraction is alsoviable.
