[Abstract]
Experimental results on extraction of essential oil and oleoresin from Guizhou's Zirzgiber corallrzium Hance by means of supercritical CO2 were presented. Effects of pressure,temperature, CO2flux,extractiontime,and particle size on yield were discussed,and differences between supercritical CO2 extraction and steamdistillation methods were compared in detail.
