-
To study the conditions and parameters for the purification of lycorine with macroporous adsorbent resin,the adsorption and desorption of nine macroporous adsorbent resins for lycorine were compared.The optimal adsorbent HPD300 and the appropriate adsorption/desorption conditions were determined,i.e.,the concentration of lycorine in extract solution was at 1.22 g/L,volume at 9BV was passed through the column at a flow rate of 2 BV/h and room temperature,the column was washed with 4 BV water at a flow rate of 2 BV/h,8 BV 70% alcohol was satisfactory eluant for desorption at a flow rate of 2 BV/h.The purity of lycorine was increased from 9.93% to 23.07%.
