Abstract: Calycosin and formononetin were efficiently extracted from Astragali Radix and purified by high-speed countercurrent chromatography. Calycosin and formononetin could be hydrolyzed from calycosin-7-glucoside and ononin, respectively. The best extraction conditions were realized by single factor… read more here.
