This is a natural medicine development technology that extracts flavones and their salts from sophora flavescens. Most of the A-ring of flavones in sophora flavescens has a lavandulyl or branched isopentenyl side chain on C8, which increased the lipophilicity of the flavones so that they can permeate through the cell membrane to reach the targets more easily in the organism. Therefore, flavones from sophora flavescens have higher antimicrobial, anti-inflammatory, anti-cancer activities and higher inhibitory activity for tyrosinase than other flavones. Through extraction, the alkaloids were separated from flavones and flavones and their salt products were obtained from sophora flavescens without the contamination of alkaloids.
