| Abstract: | A gram scale preparative supercritical fluid chromatogram was set up, with which polar compounds such as flavnoids were separated successfully on bare silica packing column by using CO 2 modifier addtive mobile phase. Influence of the operating conditions on the yield and purity were discussed. |
