YANG Yan-hong1,2,CAI Shao-xi1,ZHENG Yi-min2,XU Xiu-ying2,FU Shan-quan2(1.State Key Laboratory of Biomechanics and Tissue Engineering,Institute of Bioengineering,Chongqing University,Chongqing 400044,China;2.Institute of Bioengineering,Chongqing Institute of Technology,Chongqing 400050,China)  
Arctigenin was extracted from fruits of Arctium lappa L. by supercritical carbon dioxide.The optimal extraction conditions were:pressure 35 MPa,temperature 40 ℃,flow rate of CO2 6.0 L/h and extraction time 50 min.Arctigenin of 99.66% purity was obtained by simple degreasing of the extract under the optimal extraction conditions,and the extraction rate was 0.45% which was 2.75 times that obtained by traditional solvent-column method.So the supercritical carbon dioxide extraction was simple,safe and highly efficient.
