| Abstract: | Objective To study the technology of supercritical fluid CO_2 extraction(SFE CO_2) on urosolic acid from Cornus officinalis.Methods The effects of pressure,temperature,time,CO_2 flow rate types,and volume of entrainer on the urosolic acid extracts were studied. The optium conditions for SFE CO_2 was determined.The technology of SFE CO_2 was compared with that of traditional solvent extraction.Results The optium extraction conditions were as follows: pressure 35.0 MPa,temperature 318 K,absolute ethyl alcohol entrainer,content 4%,time 3 h and flow rate of CO_2 8 kg/h.Conclusion SFE CO_2 excels the traditional solvent extraction in yield,safety and efficiency. |
