Supercritical CO2 Extraction of Rhizoma Atractylodis Macrocephalae

摘要：

　　An orthogonal array design was employed for optimizing the supercritical CO2 extraction of Rhizoma Atractylodis Macrocephalae.The extraction was performed at temperature from 40 to 60℃,pressure from 15 to 35MPa,extraction time varying from 30 to 90min and particle size spanning from 20 to 80 mesh.The results reflect that the extraction yield is more significantly influenced by the extraction time,pressure and particle size but less by temperature.The experiments show that the extraction yield obviously increases with increasing pressure,different from the literatures.In terms of the sample origin,a comparison shows that outstanding differences exist among the extraction yields from different sources.
