    ABSTRACT This study reported a method for preparing high-purity tanshinoneⅡA by desulfonation reaction using sodium tanshinoneⅡA sulfonate as raw material. The relatively optimal reaction conditions were obtained by screening the acid reagents， temperature， solvents and their dosages. Using concentrated hydrochloric acid as a reaction reagent， acetonitrile as a solvent and reacting at 80 ℃ for 3 hours， tanshinoneⅡA with a purity of over 99% were obtained with a maximum yield of over 90%. The reaction operation of this method is simple ......
