| dc.description.abstract | The decoctions of some widespread species from the northeastern Portuguese region are traditionally used for their vulnerary properties and in the treatment of various skin disorders, wounds or burns. Juglans regia L. (walnut), Malvaneglecta Wallt.(mallow) and Scrophulariascorodonia L.(balm leave figwort)are good examples of such species. The leaves of J. regia and the aerial parts of M. neglecta are used as disinfectants and anti-inflammatory, while the aerial parts of S. scorodonia are used as a vulnerary. Furthermore, these plants are often mixed to enhance its action [1]. The present study aimed to evaluate the antioxidant activity of decoctions and methanolic extracts of the mentioned three plants.The antioxidant activity was accessed by five in vitro assays: scavenging effects on DPPH (2 ,2-diphenyl-1 -picrylhydrazyl) radicals, reducing power (measured in FolinCiocalteu and ferricyanide Prussian blue assays), inhibition of β-carotene bleaching and inhibition of lipid peroxidation in brain cell homogenates by TSARS (thiobarbituric acid reactive substances) assay. Walnut samples (methanolic extract and decoction) gave the highest antioxidant activity (lowest EC50 valuesin all the assays), followed by figwortand mallow samples. The observed antioxidant activity is certainly related to the phenolic compounds present in the studied samples and reported in another abstract presented in the same symposium. | por |
