We extracted its chemical constituents by supercritical Carbon dioxide(SFE-CO2) and steam distillation(SD). The extracts of SFE-CO2 and SD were analyzed and established by means of capillary GC/MS on HP-5(6890/5973) instrument. 75 compounds of SFE-CO2 and 55 compounds of SD were identified.Comparing the different results of the two ways, we think that the method of SFE-CO2 is superior to the method of SD in extracting and analyzing the Chinese medicinal herb.展开更多
