Abstract:
Objective To study the optimum parameters of the supercritical CO2 fluid extraction of roasted Rhizoma Atractylodis Macrocephalae and roasted Fructus aurantii immaturus,and chemical constituents of extractive matters. Methods The experiment was performed with orthogonal design. Four factors were extractive pressure,temperature,extractive time and the flow rate of CO2. GC-MS was applied for analyzing. Results The optimum condition were obtained:the extractive pressure was 33 MPa,the temperature of extraction was 40 ℃,the extractive time was 60 minutes and the flow rate of CO2 was 27 L/h. The main chemical constituents was gamma-Elemene. Conclusion The method applied to obtain the extractive matters from roasted Rhizoma Atractylodis Macrocephalae and roasted Fructus aurantii immaturus was quickly and efficiently with satisfactory results. It provides foundation for exploration.
