Thirteen phenolic compounds were isolated from Hedysarum polybotrys HAND.-MAZZ., and their structures were determined by spectroscopic studies. Among the thirteen, 5-hydroxy-2-(2-hydroxy-4-methoxyphenyl)-6-methoxybenzofuran (X) is a new compound, and 6-hydroxy-2-(2-hydroxy-4-methoxyphenyl)-benzofuran (VIII) was isolated from this plant for the first time.
