The phytochemical study of Euphorbia helioscopia afforded euphornin (1) in a large amount. Alkaline hydrolysis of 1 using potassium carbonate yielded the main product monodeacetyleuphornin (2), whose structural modification at 14-OH gave rise to 21 acylat

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.

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
