The study on the extraction of Zanthorylum bungeanum maxim volatile oil by supercritical carbon dioxide fluid

Hong Yu Guo

Abstract

In this paper,a systematic method was used to optimize the supercritical fluid extraction (SFE) of Zanthorylum bungeanum maxim volatile oil.Overall 3 variables (pressure,temperature,CO 2 dynamistic extracting volume) were considered.SFE optimize conditions:temperature 55℃,pressure 34.475 MPa,CO 2 dynamistic extracting volume 30 mL.The primary and secondary relation of the three variables is:temperatureCO 2 volumepressure.
