    Screening of Polyphenol Composition and Antiradical Capacity of Wild Erica arborea: A Native Plant Species from the Portuguese Flora
    Author(s): Alfredo Aires and Rosa Carvalho Alfredo Aires and Rosa Carvalho

    With this study, we aimed to determine the polyphenol composition and antiradical activity of activity of Erica arborea a native plant species from the Portuguese and Mediterranean flora and often reported as having important bioactivities, but without consistent scientific evidences. The analysis of polyphenol profile and content was performed by HPLC-DAD/UV-Vis and in vitro bioassay of 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+) method was used to evaluate the radical scavenging activity. The HPLC analysis showed a great diversity of compounds. E. arborea presented high contents in flavonols (52%) and flavanols (25%) and the average content of antiradical activity higher than 85%. The polyphenols identified are often associated by literature as having preventive properties and protective effect against of degenerative and inflammatory.. View More»
