文摘

A new C₂₁ steroidal glycoside, neocynapanogenin F 3-O-β-d-thevetoside 1, as well as its known aglycone neocynapanogenin 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.
