摘　　要：Three new C21 steroidal glycosides named inamoside E （1）, inamoside F （2） and inamoside G （3） were isolated from the roots of Cynanchum inamoenum （Maxim.） Loes. Their structures were determined by spectroscopic analysis, especially by ID and 2D NMR experiments.Three new C21 steroidal glycosides named inamoside E （1）, inamoside F （2） and inamoside G （3） were isolated from the roots of Cynanchum inamoenum （Maxim.） Loes.
