Abstract
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, 13C 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.
