title: Three new jatrophone-type diterpenoids from Euphorbia helioscopia.
abstract: Three new jatrophone-type diterpenoids, euphoheliosnoids A-C, together with two known related compounds, were isolated from the Chinese medicinal plant Euphorbia helioscopia L. The structures including relative stereochemistry of the new compounds were elucidated by spectroscopic methods and by comparison with known related compounds.
