Patent

CA 2288321

Processes for the production of isoflavones are described wherein plant material from plants of the genus leguminosae are contacted with water, a C1-C10 organic solvent, and optionally an enzyme which cleaves isoflavone glycosides to the aglucone form, 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, and thereafter recovering isoflavones from the organic solvent.

Procédés de production d'isoflavones qui consistent à mettre en contact de la matière végétale obtenu à partir de plantes du genre légumineuses avec de l'eau, un solvant organique C1-C10, et éventuellement une enzyme qui coupe les glycosides d'isoflavone en des isoflavones du type aglucone et ce, en vue de former un mélange. Lesdits procédés consistent ensuite à faire incuber ce mélange suffisamment longtemps pour que les isoflavones du type aglucone puissent se diviser dans le solvant organique et, ensuite, à extraire les isoflavones du solvant organique.
