Abstract
A process for recovering isoflavone values from a biomass in which the isoflavone values are extracted from the biomass with a selective solvent for the isoflavone values, solid isoflavone values and the selective solvent are contacted with a nonsolvent or antisolvent for the isoflavone value which is miscible with the selective solvent. Optionally the nonsolvent or antisolvent is admixed with water during the contact with the solid isoflavone values to improve the purity and recovery of the solid isoflavone values.
