Cordiaquinones A and B, the first examples of a new type of merosesquiterpenoid quinones, have been isolated from the roots of Cordia corymbosa. The structures of these 6-alkylsubstituted 1,4-naphthoquinones were elucidated by high field 1H NMR spectroscopy, mass spectrometry and chemical derivatization.
