摘要: A method of crystallizing docetaxel is disclosed. The method comprises (a) combining docetaxel and at least one solubilizing solvent to obtain a solution, wherein the solubilizing solvent is selected from the group consisting of acetone, methyl-tert-butyl ether, tetrahydrofuran (THF), and acetonitrile and (b) adding an anti-solvent to the solution to obtain a crystalline docetaxel, wherein the anti-solvent is water.
