ABSTRACT A structural study of depsides and depsidones by ¹H NMR and ¹³C NMR spectroscopy, in which assignments of all carbons/protons of compounds isolated from various lichens (Thamnolia vermicularis, Baeomyces roseus and Everniastrum cirrhatum) is reported. The compounds studied include thamnolic acid, decarboxythamnolic acid, baeomycesic acid, salazinic acid and atranorin. The assignments are based on variuos 1D and 2D NMR experiments, e.g. DEPT, COSY, HMQC and HMBC

Keywords : Lichen; depside; depsidone; structure determination.
