The invention relates to a method for the purification of L-hercynine. Said method for the purification of L-hercynine, from a reaction mixture resulting from the reaction of L-histidine, in controlled pH conditions, with a methylating agent Me X in a polar solvent or a mixture of polar solvents, at room temperature, is characterised in that it comprises at least one step of separating the organic products from the inorganic salts formed during the reaction by electrodialysis. This method allows the L-hercynine losses to be limited during the purification.
