Abstract
Processes for the production of isoflavones are described wherein plant material from plants of the genus leguminosae are contacted with water, an enzyme which cleaves isoflavone glycosides to the aglucone form and a C.sub.2 -C.sub.10 organic solvent, so as to form a combination, incubating the combination for a time sufficient to allow isoflavones of the aglucone form to partition into the organic solvent component, and thereafter recovering isoflavones from the organic solvent component.

A process for the production of isoflavones from plants of the genus Leguminosae which comprises a contacting plant material with water, a supplemental enzyme which cleaves isoflavone glycosides to the aglucone form, and a C.sub.2 -C.sub.10 organic solvent to form a combination, incubating the combination for a time sufficient to allow isoflavones of the aglucone form to partition into the organic solvent component, and thereafter recovering isoflavones from the organic solvent component.
