| 摘 要： | 【目的】分析比较麻黄及蜜麻黄超临界萃取物的化学成分。【方法】采用超临界CO2萃取技术(SFE-CO2法)从麻黄及蜜麻黄中提取挥发油,并用气相色谱-质谱联用(GC-MS)技术分离、鉴定,比较两者化学组成的不同。【结果】生麻黄中的硫酸二乙酯等20种成分在蜜麻黄中没有检出,而在蜜麻黄中检测到羟甲基糠醛等12种不同成分。挥发油得率：麻黄2．1％,蜜麻黄1．0％。【结论】麻黄与蜜麻黄超临界萃取物的化学成分有明显差异。

| 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. |
