The invention discloses a method for preparing taxol, docetaxel and other taxanes. The taxanes synthesized or semi-synthesized or extracted from the plants are used as the raw materials, the waterborne solvent is used to dissolve the materials, and the macroporous absorption resins such as Diaion Hp resins, Amberlite XAD resins are used as the stationery phase, the organic solvents such as THF, N, N-DMF and other solvents are used as the eluent, the atmospheric pressure column chromatography is adopted, one step is enough to extract the taxanes with the purity above 99.90% with high yield above 99.0%. The invention has the advantages of simple method, convenient operation, favorableness to production expansion, small amount and recyclability of organic solvent and environmental friendliness.
