Abstract

The invention discloses a method for electrochemically preparing a berberine reduction product. The method comprises the following steps: electrifying a mixed electrolyte in an electrolysis reactor provided with an anode plate and a cathode plate to carry out electrochemical reaction; the mixed electrolyte comprises a first organic solvent, an electrolyte and free berberine; the concentration of the free berberine dissolved in the organic solvent is 0.1-10.0 mol / L, and the molar weight of the electrolyte is 20-100% of the molar weight of the free berberine; the berberine reduction product is dihydroberberine and / or tetrahydroberberine. The method disclosed by the invention is simple to operate, the use of a noble metal catalyst is avoided, the prepared product is high in yield, good in purity and few in byproducts, and the solvent and filtrate can be recycled.
