Resumen
Las plantas suponen una gran fuente de compuestos bioactivos, especialmente de polifenoles, bien conocidos por su actividad antioxidante entre otros muchos beneficios para la salud. En el presente Trabajo de Fin de Grado se ha llevado a cabo la determinación del perfil fenólico de la planta Limonium quesadense. Para ello se recogieron muestras de plantas en cinco localizaciones diferentes situadas en las localidades de Priego de Córdoba (Córdoba) y Alcaudete (Jaén), se obtuvieron sus extractos fenólicos con metanol y se analizó su composición empleando la técnica de Cromatografía de Líquidos de Alta Resolución acoplada a Espectrometría de Masas (HPLC-ESI-QTOF-MS). Se identificaron un total de veintinueve compuestos, que consistían mayoritariamente en ácidos fenólicos y flavonoides, y se comprobó cuáles eran los principales compuestos para poder llevar a cabo una comparación con otras especies del género Limonium.

In the present Final Degree Project, the phenolic profile of the plant Limonium quesadense was determined. Plant samples were collected from five different locations in Priego de Córdoba (Córdoba) and Alcaudete (Jaén), their phenolic extracts were obtained with methanol, and their composition was analyzed using High-Performance Liquid Chromatography coupled to Mass Spectrometry (HPLC-ESI-QTOF-MS). Twenty-nine compounds were identified, consisting mainly of phenolic acids and flavonoids. The obtained composition was checked against the results previous reported in other species of the genus Limonium.
