Resumen

Phytochemical investigation of the above-ground biomass of Asclepias sullivantii L. (Asclepiadaceae) afforded six new pregnane glycosides, named sullivantosides A-F (1–6). The structures of 1–6 were elucidated through a variety of spectroscopic and spectrometric techniques (1D and 2D NMR; HRESIMS). To the best of our knowledge, this work represents the first phytochemical study of this species.
