Abstract
Objective:
To study the chemical constituents in the root of Hedysarum polybotrys Hand.-Mazz..
Method:
The constituents were isolated by Sephadex LH-20 and silica gel column chromatography, and their structures were identified on the basis of spectral analysis.
Result:
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.
Conclusion:
Compounds II, III, V were obtained from the plant for the first time.
