Abstract:
To compare the chemical components of supercritical extracts from Herba Ephedrae and honey-prepared Herba Ephedrae. Volatile oils were extracted from Herba Ephedrae and honey-prepared Herba Ephedrae by supercritical CO 2 extraction and then identified by the combination of gas chromatography and mass spectrometry (GC-MS). Twenty kinds of components such as diethylsulfate obtained from Herba Ephedrae were not found in honey-prepared Herba Ephedrae and twelve different components such as hydroxymethylfurfural were obtained from honey-prepared Herba Ephedrae. The extraction rate of volatile oils was 2.1% in herba ephedrae and 1.0% in honey-prepared Herba Ephedrae. [ Conclusion]The components of supercritical extractions from Herba Ephedrae differ from those in honey-prepared Herba Ephedrae.
