ThechloroformextractofthePeruvianlichenEverniopsis trulla, were isolated four metabolites, being three already reported in the literature (usnic acid, atranorin, Ethyl haematommate) and a new, which were identified and elucidated by one-dimensional spectroscopic techniques (1 H-NMR, 13C-NMR DEPT) and two-dimensional (COSY, HMBC and NOESY), mass spectrometry and IR and UV spectroscopy. This work is the first chemical study of lichen Everniopsis trulla.
