摘要：Six new C21 steroidal glycosides 1 - 6 were isolated from the stem parts of Cynanchum bungei Decne. The structures of the new glycosides were determined on the basis of spectroscopic analysis, including 1D- and 2D-NMR and HR-ESI-MS techniques as well as by comparison of their spectral data with those of related compounds. ? 2008 Verlag Helvetica Chimica Acta AG.
