Structural determination of saponins from Hedysarum polybotrys.
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, 1H-1H COSY and NOESY permitted correct assignments of all 1H and 13C signals of 1 and 2, and the 13C NMR data of 2 were reported for the first time.
