Abstract
Pharmaceutically potent flavone compound isokaempferide was isolated first time from Acalypha alnifolia by a method of column chromatography. Based on the solvent nature the crude extracts obtained from the plant leaf. The high polar solvent extracts gave better antioxidant and pharmacological activities which mainly coincident with secondary metabolites quantity. The acetone extract have focused for compound isolation because of its better activity than methanol extract in most of the experimental attempt. By the way acetone extract engaged through the column chromatography with sequential changes in mobile phase from low to high polar solvents. This successivemobile phase is lying behind the compoundseparation from the crude. The chloroform :ethylacetate fraction of silica gel column chromatography yields isokaempferide better from acetone extract of A. alnifolia. Though isokaempferide isolated previously from other sources this method of isolation from Acalypha alnifolia is the first effort and easily achievable.
