FIELD: pharmaceuticals.
SUBSTANCE: invention relates to pharmaceutical industry, namely to method for producing copper-containing arabinogalactan sulfate derivatives. Process for preparation of copper-containing derivatives of arabinogalactan sulfate, comprising: to an aqueous solution containing arabinogalactan sulfate, copper (II) chloride dissolved in ethanol is gradually added dropwise, the resulting resinous precipitate is washed with ethanol, filtered, and washed on the filter with acetone to give a crystalline precipitate.
EFFECT: above described method allows to simplify the process of obtaining copper-containing derivatives of arabinogalactan sulfate by reducing its duration, increase its economic efficiency by eliminating the use of ion exchange resin.
