Process for isolating phenolic compounds |
| abstract |
The invention provides compositions and methods for isolating phenolic compounds, particularly isoflavones, from aqueous extracts of plant materials that contain such compounds. The process comprising: (a) providing an aqueous plant extract at a first pH less than 10, the aqueous plant extract comprising a plurality of phenolic compounds; (b) extracting the aqueous plant extract with a first organic solvent to yield a first organic extract; (c) extracting the first organic extract with an aqueous phase of pH greater than 10 to yield a phenol rich aqueous phase; (d) adjusting the pH of the phenol rich aqueous phase to a pH of less than 9; and (e) isolating the phenolic compounds from the phenol rich aqueous phase. |
