CASTRO M, O.N; SANTIAGO, J  e  ALVAREZ, J. Aislamiento y elucidación estructural de un compuesto nitrogenado y del haematomato de etilo del liquen Everniopsis trulla. Rev. Soc. Quím. Perú [online]. 2017, vol.83, n.2, pp.131-142. ISSN 1810-634X.

The chloroform extract of the Peruvian lichen Everniopsis 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 (1H-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.

Palavras-chave : usnic acid; atranorin; Everniopsis trulla; ethyl haematommate; lichen.
