✦ Synopsis

In addition to euphornin, three new toxic substances (euphornins A, B and C) have been isolated from the plant Euphorbia helioscopia L., and their absolute stereostructures also been elucidated on the basis of their spectral data and some chemical evidence together with an X-ray crystallographic analysis of the p-bromobenzoate derived from euphornin.

-Furthermore, their conformations have also been discussed.
