Existen dos series de ácidos grasos esenciales, las cuales no pueden ser sintetizados por los humanos y deben ser suministrados mediante la dieta. Estas series son el omega-6 y el omega-3. Los omega-6 son derivados del acido linoleico y los omega-3 del alpha­ linolénico. De estos ácidos grasos poliinsaturados son sintetizados el acido araquidónico (ARA), eicosapentaenoico (EPA) y el docosahexaenoico (DHA). ·La finalidad de la investigación fue evaluar el efecto de tres dietas de tejidos vegetales, aguaje (Mauritia flexuosa), ungurahui (Oenocarpus bataua), y papailla (Jacaratia digitata) en el extracto etéreo de las larvas del Rhynchophorus palmarum y en los ácidos grasos esenciales (omega 3 y omega 6) presentes en su aceite. El aceite se obtuvo por extracción con solvente orgánico (hexano) en un equipo soxhlet, previo secado de las muestras a 50°C por tres horas. Fueron detec...

Recently, interest in studying pigments from lichens has been aroused due to their bioactive properties and health benefits. The Geolashon (Teloschistes flavicans) is a thousand-year-old lichen from the Peruvian Andes characterized by its yellow filaments, traditionally used by the Peruvian inhabitants as a natural pigment for making handicrafts and medicinal purposes. In this sense, this article aims to compile all the studies on Geolashon as a source of natural yellow pigments, starting from its importance and applications by the Andean population to research on obtaining, characterizing, and properties of its extracts. Although studies on this lichen are limited, it was observed that the obtained from lichen are rich in 3-[1’-(2”,3”-dihydroxy-phenyl)-propyl]-7-hydroxy- chroman-4-one, vicanicin, parietin, other compounds and has antidiabetic, antibacterial, antileukemic, antimicr...
