Triterpenos y Esteroles de Salvia Leucantha (Lamiaceae) y Evaluación de su Capacidad Antioxidante

Abstract

<p class="Default">Con el fin de contribuir en el conocimiento de la flora Colombiana, particularmente aquella presente en la región del Guavio, se eligió la especie <em>Salvia leucantha </em>para realizar un estudio fitoquímico preliminar de su composición química y bioactividad a nivel antioxidante. Para ello se realizó el análisis fitoquímico preliminar de hojas y se evaluó la presencia de los principales grupos de metabolitos secundarios, cuyas estructuras fueron analizadas tentativamente por CG-EM y respectiva comparación con las bases de datos NIST-08, adicionalmente se evaluó la actividad antioxidante de extractos y fracciones por DPPH. Se de­tectó la presencia de triterpenos pentaciclicos en gran concentración, lo cual era de esperarse al tratarse de una especie del género <em>Salvia</em>, ampliamente conocida por su contenido de terpenos y amplia gama de aceites esenciales. Estos compuestos son ampliamente utilizados en la industria alimenticia, cosmética y farmacéutica por sus propiedades físico-químicas y farmacológicas, pero no reportan porcentajes de inhibición altos para poderlos catalogar como antioxidantes fuertes. Los resultados de este trabajo son importantes como primera aproximación a la ampliación del conocimiento químico y a la posible utilidad de las especies presentes en esta zona de Colombia con características agronómicas óptimas para el es­tablecimiento de cultivos, que permitan una utilización racional de los recursos naturales de nuestro país, como fuente de desarrollo regional y nacional.</p>
