The aqueous digest solution of the corm of Lycoris radiata or its extract was treated with weakly acidic ion exchange resin (Amberlite IRC-50) to adsorb the alkaloids and separate them from non-alkaloidal substances. The alkaloids were desorbed with ammoniacal ethanol and the ethanol was evaporated from this solution of total alkaloids. The residual solution was passed through double columns of Celite, with phosphate buffer (pH 7.0) as the stationary phase. The column was eluted with chloroform to separate lycorine and determination by optical method gave a satisfactory result.
