Abstract:
A method for the production of an antitumorous remedy which compriseshydrolysis-extracting of lignin-containing raw material in a basic medium, oxidizing of treated material with oxygen-containing gas, separating of the liquid phase and its acidification, separating of a precipitate obtained and washing the precipitate until neutral pH-value is reached, drying the precipitate, blending the precipitate with pyrophosphate, dissolution of the blend in water while heating and adding NaCl into the dissolved blend thereby obtaining the desired product, adding HCl into the desired product until neutral pH-value is reached and the product of lignin basic hydrolysis and oxidation is mixed with pyrophosphate at a dry mass ratio of 25:17 accurate up to Â±10%.
