Abstract The roots of Seneciomexicanus afforded a new oplopane derivative whose structure was elucidated by spectroscopic methods and by treatment with p -toluenesulphonic acid, which yielded three isomeric substances. The stereochemistry of the natural product followed from X-ray crystallography and its absolute configuration from the optical activity.
