Study on the supercritical CO_2 extraction of alkaloids from sophora flavescens ait

Zhang Li

Abstract

The extraction of alkaloids from sophora flavescens ait with CO2SFE was studied.By use of orthogonal design ,the effects of pressure,temperature and time on extractabilities of alkaloids were studied.The results showed that the optimum conditions of CO2SFE were:pressure 30 MPa,temperature 45℃,time 5h for the extraction,with NH4OH as an alkalizer and MeOH as an entrainer.The extraction rate of supercritical CO2 fluid extraction was about 24 times as that of traditional solvent extraction.
