By studying the factors that affect the purities of products and recoveries of isoflavones, we got the optimum conditions for desorption: 70℃, eluting solvent sequence: water 3.0 BV, 75% ethanol 5.0 BV, flow-rate 2.5 mL·min~(-1). Under these conditions, the content of isoflavones in the product was 56.0% with the recovery of 89.3%. The content of isoflavones in the product was ten times larger than in the initial material.
