CASTRO MANDUJANO, Olivio Nino. Contribution to the phytochemistry study of the lichen Thamnolia vermicularis subsp.Vermicularis s. STR.. Rev. Soc. Quím. Perú [online]. 2010, vol.76, n.4, pp.322-329. ISSN 1810-634X.

In the present work there was investigated the Thamnolia vermicularis (Sw.) Ach. Ex-. Schaer. Subsp. Vermicularis. Two successive extractions were done by maceration in acetone; one proceeded to separate diverse components of the extract, for it there were used solvents and mixtures of solvents of increasing polarity; then isolated and purified by means of chromatographic techniques and recrystallizations. Finally, they were elucidated and there decided the structures of the obtained solids; analyzing his spectra of IR, H¹-NMR, C¹³-NMR and SM; these are: compound H (decarboxithamnolic acid), and the compound D (thamnolic acid)

Palabras clave : Liichen; Thamnolia vermicularis; thamnolic acid; decarboxithamnolic acid.
