Four saponins (1–4) were isolated from the roots of Hedysarum polybotrys Hand.‐Mazz. and obtained from Hedysarum (Tourn.) L for the first time. Their structures were identified on the basis of spectroscopic data. MS, 1D and 2D NMR including HMQC, HMBC, 1 H– 1 H COSY and NOESY permitted correct assignments of all 1 H and 13 C signals of 1 and 2 , and the 13 C NMR data of 2 were reported for the first time.
