Caracterización y determinación del poder antioxidante y actividad biocida de tres especies del Género Eupatorium

Abstract

En la actualidad existe un gran interés en la utilización de extractos vegetales en las formulaciones cosméticas, en algunos casos por sus propiedades antimicrobianas y antioxidantes. En nuestro país existe una gran cantidad de especies vegetales utilizadas en medicina tradicional. Nuestro grupo de trabajo tiene una larga trayectoria en la investigación de la composición química y actividades biológicas estas especies autóctonas. Entre estas, se seleccionaron tres especies pertenecientes al género Eupatorium (Asteraceae): Eupatorium candolleanum, E. hecatanthum y E. macrocephalum para el estudio de sus actividades biocida y antioxidante. Se determinó el poder antioxidante mediante la técnica de TRAP (Total Reactive Antioxidant Potential) y se verificó la actividad biocida mediante un sistema clásico basado en difusión sobre agar Mueller Hinton. Solamente el extracto de E. candolleanum presentó una marcada actividad inhibitoria frente a Candida albicans. Todos los extractos de estas especies presentaron actividad antioxidante, siendo el extracto de E. candolleanum el más activo. Se realizó la caracterización de los extractos hidroalcohólicos por TLC y HPLC/DAD. Los análisis cromatográficos obtenidos indicaron la presencia de compuestos polifenólicos del tipo flavonoide (derivados de la quercetina) y de tipo fenilpropanoide. La actividad antioxidante de estos extractos, debida probablemente a su contenido en compuestos polifenólicos, los hace potencialmente promisorios para su aplicación cosmética.

There is currently a great interest in the use of plant extracts in cosmetic, primarily for its biological properties, such as antimicrobial and antioxidant. In our country there are a lot of species used in traditional medicine. Our working group has a long history in the research of the chemical composition and biological activities of these native species. Three species, belonging to the genera Eupatorium (Asteraceae): Eupatorium candolleanum, E. hecatanthum and E. macrocephalum were selected for the study of their antioxidant and biocidal effects. The antioxidant power was determined by the TRAP technique (Total Reactive Antioxidant Potential). Biocidal activity was assayed using a classical Mueller Hinton agar based system. E. candolleanum showed a marked inhibitory activity against Candida albicans. All the extracts presented antioxidant activity, being E. candolleanum extract the most active. Also, characterization of the hydroalcoholic extracts of these species by TLC and HPLC/DAD was performed. Chromatographical analysis indicated the presence of polyphenolic compounds of the flavonoid and phenylpropanoid type. The antioxidant activity of these extracts, probably due to its content in polyphenolic compounds, makes them interesting ingredients for cosmetic application.
