Abstract Three new isoflavans, 7- O -methylisomucronulatol, isomucronulatol 7,2′-di- O -glucoside, 5′-hydroxyisomucronulatol 2′,5′-di- O -glucoside, and one new pterocarpan, 3,9-di- O -methylnissolin were isolated from Astragalus mongholicus roots. Their structures were established by spectral analyses and chemical conversions.
