Patent number: 5679806Abstract: The present invention relates to a process for the isolation and purification of isoflavones from a number of different biomass sources. More particularly, the present invention relates to a three-step process whereby a biomass containing isoflavones with a solvent thereby forming an extract that is subsequently fractionated using a reverse phase matrix in combination with a step gradient elution, wherein the resulting fractions eluted from the column contain specific isoflavones that are later crystallized. The purified isoflavone glycosides may then be hydrolyzed to their respective aglycone.Type: GrantFiled: February 24, 1995Date of Patent: October 21, 1997Assignee: Hauser, Inc.Inventors: BoLin Zheng, John A. Yegge, David T. Bailey, James L. Sullivan
