Two new toxic substances, euphoscopins A and B, have been isolated from the plant Euphorbia helioscopia L., and their absolute stereostructures also been elucidated on the basis of their spectral data coupled with an X-ray crystallographic analysis of the p-bromobenzoate readily obtained on treatment of euphoscopin A with p-bromobenzoyl chloride - pyridine. These antitumor substances belong to a group of jatrophone-type diterpenes.
