A new C₂₁ steroidal glycoside, neocynapanogenin F 3-O-β-D-thevetoside 1, as well as its known aglycone neocynapanogerin F 2, which have an aberrant 13, 14:14, 15-disecopregnane-type skeleton were isolated from the root of Cynanchum paniculatum.Their structures were elucidated on the basis of spectroscopic data analysis. These compounds showed certain cytotoxic activities in vitro.
