CASTRO MANDUJANO, Olivio Nino. Contribution to the phytochemistry study of the Psiloparmelia distincta (Nyl.) Hale. Rev. Soc. Quím. Perú [online]. 2011, vol.77, n.1, pp.56-65. ISSN 1810-634X.
In the present work was realized the isolation and study of lichen substances of the Psiloparmelia distincta (Nyl.). Successive extractions were done by acetone and methanol. It was separated and purified some compounds of the extracts, using solvents and mixtures of solvents of increasing polarity, in diverse chromatographic methods and recrystallizations. They were elucidated and decided the structures of the obtained compounds, analyzing his spectra of UV, IR, RMN-H1 RMN-C13, DEPT and EM; these compounds are: H (acid 2-hydroxi-3-formil-4-etoxi-6-methyl-benzoic), A (acid fumarprotocetrárico).
