✦ Synopsis

Abstract

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.
