Abstract:
To compare the chemical components and their contents of essential oil extracted from Radix Angelicae Sinensis by the methods of supercritical CO 2 fluid extraction (SFE-CO 2), normal pressure steam distillation (NPSD) and vacuum steam distillation (VSD). The combination of gas chromatography and mass spectrometry was applied to analyze the chemical components and their contents of essential oil extracted from Radix Angelicae Sinensis.The chemical components and their contents of essential oil extracted by the above three methods were different.[Conclusion]SFE-CO 2 is superior to VSD and NPSD in raising yield and shortening extractive time. It is a good method for the extraction of essential oils from Radix Angelicae Sinensis.
