To study the chemical constituents of Hedysarum polybotrys. Chromatographic methods were used to isolate compounds from H. polybotrys and chemical and spectral methods were used to elucidate the structures of the isolated compounds. Five compounds, N,N,N-trimethyl-tropaphone inner salt (hypaphorine) (1), octadecyl-3-methoxy-4-hydroxy-benzeneacrylate (2), 5,7,4'-trihydroxy-dihydroflavanone 5,7-di-O-beta-D-glucopyranoside (3), 3,4,5-trimethoxy cinnamic acid methy ester (4) and vanillic acid (5), were isolated from the roots of H. polybotrys. Compounds 1, 2 and 3 were obtained from this plant for the first time, while compounds 1 and 2 were isolated from Hedysarum for the first time.
