Abstract
The invention relates to a method for purifying 20(S) camptothecin by transforming the lactone ring of the 20(S) camptothecin into a carboxylate salt with the help of an aqueous base, hydrogenating the mixture that is obtained in the presence of a transition metal catalyst, acidifying the aqueous phase to form camptothecin crystals, adding a polar aprotic solvent, optionally heating and cooling the mixture and separating the camptothecin crystals.
