CUELLAR, M et al. PHENOLICS, DEPSIDES AND TRITERPENES FROM THE CHILEAN LICHEN PSEUDOCYPHELLARIA NUDATA (ZAHLBR.) D.J. GALLOWAY. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.3, pp.1624-1625. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072008000300017.

The lichen Pseudocyphellaria nudata is a species endemic to southern South América. From the lichen tallus, methyl orsellinate, 2-methoxy-3,6-dimethyl-4-hydroxybenzaldehyde, methyl-evernate, tenuiorin, hopan-6ß,22-diol and hopan-6á,76,22-triol were isolated and identified as the main lichen constituents. This is the first report of the occurrence of 2-methoxy-3,6-dimethyl-4-hydroxybenzaldehyde in lichens

Palavras-chave : Pseudocyphellaria nudata; lichen; monophenols; depsides; triterpenes.
