In this research on the activeconstituents of sweet potato, nine compounds were isolated and identified, including seven new resin glycosides, batatosides A-G (1- 7), along with two known compounds, batatinoside I ( 8) and simonin IV ( 9). The structures of 1- 9 have been established by a combination of spectroscopic and chemical methods. The major characteristics of the new compounds are the presence
