Two known, but previously uncharacterized, ent-kaurenic acid derivatives, 1 and 2, and four new sesquiterpenes of the eudesmanolide type, 3-6, have been isolated from Wedelia prostata. The structures were eludidated by a range of 1D and 2D high field nmr techniques, and the stereochemistry of the new eudesmanolides was defined from a combination of coupling constant analyses and nuclear Overhauser difference spectra.
