DITERPENES FROM EUPHORBIA HELIOSCOPIA
A number of diterpenes have been isolated from Euphorbia helioscopia and their stereostructures elucidated on the basis of the spectral data together with some chemical evidence.The absolute configuration of euphoscopin A and euphornin in particular have been unambiguously determined by means of X-ray crystallographic analysis.Key Word Index - Euphorbia helioscopia; Euphorbiaceae; toxic diterpenes; euphoscopins; epieuphoscopins; euphornins; euphohelioscopins; euphohelionone.

STRUCTURAL AND CONFORMATIONAL STUDIES ON EUPHORNIN AND RELATED DITERPENES
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 evidenc
