Abstract: Esta tesis describe el aislamiento y elucidación estructural de metabolitos secundarios de los extractos acetónicos de los líquenes Xanthoparmelia tasmanica (X tasmanica) y Xanthomendoza mendozae (X mendozae), colectados en el distrito de Muquiyauyo, provincia de Jauja (Departamento de Junín, 3200 msnm). Las estructuras de estos compuestos fueron elucidados por una combinación de métodos espectroscópicos y químicos. Cabe mencionar que los resultados de esta tesis son las primeras informaciones que se relatan a cerca del estudio químico de X tasmanica y X mendosae.
Fue realizado un análisis cualitativo de los metabolitos secundarios para ambos líquenes. Este análisis infirió que el liquen X tasmanica contiene aminogrupos primarios o secundarios (++), grupos fenólicos libres (+), taninos (+), alcaloides (+), catequinas (+), triterpenos y esteroides (+), mientras que el liquen X mendozae contiene aminogrupos primarios o secundarios (++), grupos fenólicos libres (+), taninos (+), alcaloides (+), catequinas (+), triterpenos y esteroides (+).
Del liquen X. tasmanica se aisló el (+) acido único que fue elucidado por sus datos espectroscópicos (RMN *H, IR y EM) mientras que del liquen X. mendozae se aisló la antraquinona parietina (fisciona) que por derivatización de ésta en su forma acetilada se elucidó su estructura a través de sus espectros mono y bidimensional (RMN H, RMN I3C. HMBC, IR y EM).
De ambos líquenes se detectó por CG-EM y RMN 'H mezcla de ácidos grasos y compuestos con estructuras base de antraquinonas. Actualmente sigue trabajándose en esta investigación, pero por factor de tiempo y cumplimiento de las normas de la dirección de la Postgraduación se tuvo que redactar la tesis con estos resultados.
This thesis describes the isolation and structural elucidation of secondary metabolites and liquenic compounds of the accione extracts from Xanthoparmelia tasmanica (X tasmanica) and Xanthomendoza mendazae (X mendozae) lichens and Ihey were collected in Muquiyauyo District, Jauja province (Junín, 3200 m). The structures of these compounds were characterized by combination of chemical and spectroscopic methods. These results are the fírst information that relate about to the chemical study of X, tasmanica and X mendozae. The qualitative analysis of the secondary metabolites for both lichens was carned out. This analysis concluded that the lichen X. tasmanica contains primary or secondary aminogrupos (++), free phenolic groups (+), tannins (+), alkaloids (+), catechins (+), triterpenes and steroids (+), while that lichen X. mendozae contains primary or secondary aminogrupos (+), free phenolic groups (+), tannins (+), alkaloids (+), catechins (+), triterpenes and steroids (+). +) usnic acid was isolated from lichen X. tasmanica and the molecular structure was elucidated by spectroscopic data (RMN H, IR y EM). The anthraquinone panetin (physcion) was isolaíed from lichen X. mendozae and was possible to confirm its structure through acetylated parietin. The molecular structure was characterized by means of their respective spectral data (RMN H, RMN 13C, IR y EM) including bidimensional experiment (HMBC). GC-MS and NMR H analysis of both lichens revealed that they contained a mixture of fatty acids and anthraquinones based structures. Currently still working on this research, but by time factor and compliance of Postgraduate Depart rulers this work stopped and this thesis has been written with these results.
