The stereostructures and molecular conformations of four more diterpene
lactones, gelomulides G-J, isolated as minor constituents from the leaves
of Gelonium multiflorum were established on the basis of their ^1H NMR,
^1^3C NMR and mass spectral evidence. Additionally, a 2D NMR spectral study
and the ORTEP diagram derived from the X-ray crystallographic analysis of
gelomulide I confirmed its proposed stereostructure and absolute
configuration.
