Three new prenylfuranoisoflavonoids, namely, 5‐hydroxy‐7‐(2‐hydroxyisopropyl)‐4′‐methoxy‐9‐prenylfurano [3,2‐ g ]isoflavone ( 1 ), 5‐hydroxy‐4′‐methoxy‐9‐prenylfurano[3,2‐ g ]isoflavone ( 2 ), 5‐hydroxy‐4′‐methoxy‐7‐prenyl‐furano[2,3‐ h ]isoflavone ( 3 ) were isolated from the roots of Hedysarum scopariu and structurally established by means of detailed spectroscopic analyses (IR, EI‐ or HR‐ESI‐MS as well as 1D‐ and 2D‐NMR), and by comparison of their spectroscopic data with those reported for structurally related compounds.
