ABSTRACT

Different analyses were carried out on the following plant species: Adesmia boronioides Hook.F., Senecio patagonicus Hook. & Arn. and Lepidophyllum cupressiforme (Lam.) Cass. in order to compare the photosynthetic pigment, carotenoid and phenylpropanoid contents. Total phenolic content and antioxidant capacity were measured by using common established reagents: Folin-Ciocalteau and ABTS respectively. Plant samples were collected from specimens growing inside the National Park Pali Aike and the Botanic Garden Carl Skottsberg in Punta Arenas city. The results showed no marked tendencies between photosynthetic pigments. Nevertheless, a good correlation was found among the antioxidant capacity and phenolic compounds. Furthermore, species growing in the Pali Aike National Park seem to be more adapted to the environmental conditions.


Se realizaron diferentes análisis al contenido de pigmentos fotosintéticos, carotenoides y fenilpropanoides. El contenido de fenoles totales y la capacidad antioxidante se midieron usando reactivos ampliamente conocidos: Folin-Ciocalteau y ABTS respectivamente en las siguientes especies: Adesmia boronioides, Senecio patagonicus y Lepidophyllum cupressiforme. Estas plantas se encuentran en el Parque Nacional Pali Aike y en el Jardín Botánico Carl Skottsberg en la ciudad de Punta Arenas. Los resultados no muestran una tendencia clara entre las muestras de pigmentos fotosintéticos. Sin embargo, se pudo observar una buena correlación entre la capacidad antioxidante y el contenido de compuestos fenólicos. Además, aparentemente las especies que crecen en el Parque Nacional Pali Aike están más adaptadas a esas condiciones ambientales.
