| Abstract: | 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. |
