Abstract

In this paper,the spercritieal CO_2extraction method was compared with ethanol distillation extraction method,and GC-MS was used as determination method.The results indicated that supercritical CO_2extraction has advantages of high efficiency,high selectivity,short distilling time and less solvent residue.The optimum technical condition of supercritical CO_2 extraction were found through orthogonal experiment:particle size 40W,operating time 1.0h,temperature 45℃,working pressure 33MPa.
