摘　　要：目的优选超临界CO2萃取乳香的工艺条件。方法:正交法设计萃取工艺,GC法测定超临界CO2萃取物中α-蒎烯和乙酸辛酯的含量,以此为指标综合评价各工艺。结果超临界CO2萃取乳香最佳工艺为:萃取压力(P)为25MPa,温度(T)为55℃,萃取时间(t)为6h。结论超临界CO2萃取效率较高,该方法适于乳香的提取。OBJECTIVE To optimize the extraction process of olibanum by SFE-CO2. METHODS Orthogonal design was applied and GC was used to determine the contents of α-pinene and acetic octyl ester to optimize the process. RESULTS The optimized preparation was as follows： pressure 25MPa,temperature 55℃ and extraction time 6h. CONCLUSION The method of SFE-CO2 is rapid, convenient compared with conventional methods.
