    • PURPOSE: A method for purifying paclitaxel is provided, thereby effectively and cheaply purifying paclitaxel in a relative short period to obtain paclitaxel with 99.5% or more of purity. CONSTITUTION: The method for purifying paclitaxel comprises the steps of: (a) adding organic solvent into Taxus genus to prepare an extract of Taxus genus and concentrating the extract; (b) adding organic solvent into the concentration of Taxus genus and separating the organic solvent layer; (c) treating the extract of Taxus genus with synthetic adsorbing agent, filtering the treated extract, and adding hexane into the filtered solution to obtain the precipitate; (d) dissolving the precipitate in organic solvent and subjecting the solution to normal-phase chromatography using developing solvent selected from dichloromethane, benzene, acetone and ethyl acetate to obtain an active fraction; and (e) subjecting the active fraction to high performance liquid chromatography.
