Abstract:
Object To establish the process of supercritical CO 2 extraction of glycyrrhetic acid from Glycyrrhiza uralensis Fisch.. Methods The comparison methods among supercritical CO 2 extraction, Soxhleth extraction and ultrasonic extraction were conducted. Results The optimized supercritical CO 2 extraction conditions were 30 MPa, pressure; 70 meshes, granularity of material; 80% ethanol, modifying agent; 45 ℃, extraction temperature; 2 hours, extraction time. Conclusion The results show that supercritical CO 2 extraction has an advantage over any other extractions of glycyrrhetic acid from G. uralensis.
