[Studies on chemical constituents in the root of Hedysarum polybotrys].
OBJECTIVE
To study the chemical constituents in the root of Hedysarum polybotrys Hand.-Mazz..


METHODS
The constituents were isolated by Sephadex LH-20 and silica gel column chromatography, and their structures were identified on the basis of spectral analysis.


RESULTS
Five compounds, medicarpin (I), 3-hydroxy-9-methoxycoumestan (II), 3, 9-dihydroxycoumestan (III), beta-sitosterol (IV), beta-sitosterol-3-O-beta-D-glucoside (V) were obtained.


CONCLUSIONS
Compounds II, III, V were obtained from the plant for the first time.
