Resumo
\\\\nNatural antioxidants as nutritional supplements have gained increasing importance over the last years,due to their general lower toxicity and side effects. Halophyte plants are considered an important reser-voir of bioactive molecules with multiple biotechnological applications, including antioxidant. This studyreports for the first time the antioxidant activity and the phenolic composition of methanol extracts ofdifferent anatomical parts of Limonium algarvense Erben, an endemic halophyte species of the South-west area of the Iberian Peninsula. Antioxidant activity was determined by different assay systems,namely radical scavenging activity (RSA) on 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals and on nitric oxide (NO), ferric reducing antioxidantpower (FRAP), and metal chelating activity on iron and copper. The total phenolics, flavonoids, tannins,hydroxycinnamic acids, anthocyanins, flavones and flavonols are also reported, along with the phenoliccomposition determined by High Performance Liquid Chromatography (HPLC). In general flowers hadthe highest antioxidant activity, coupled with the highest levels of phenolics. Gallic acid (GA) and cate-chin were the main component in flowers, roots, and peduncles and in leaves there was a dominance ofepigallocatechin gallate and GA. Our results suggest that L. algarvense, particularly its flowers, is a promis-ing source of bioactive antioxidants with potential applications in several fields, such as the agro-foodindustry, namely as functional beverage.\\\\n
