Abstract:Two new isoflavones (8, 3‘-dihydroxy-7,4‘-dimethoxyisoflavone, odomtin-7-O-β-D-glu-copyranoside) and four known isoflavones (formononetin, 7,3‘ -dihydroxy-8,4‘-dimethoxyisoflavone, ealyeosin, ealycosin-7-O-β-D-glucopyranoside) were isolated from the roots of Astragalus merebtm (Fiseh.) Bunge. Their structures were established by spectral analysis.
