Chemical Characterization and Biological Properties Assessment of Euphorbia res...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Matos, Isabel; El Ghadraoui, Lahsen; Costa, Maria Clara; Carlier, Jorge D.; Faleiro, Maria LeonorAlthough the plants of the genus Euphorbia are largely exploited by therapists in Morocco, the composition and antibacterial activities of propolis from these plants are still unknown. To address this gap, this study aimed to characterize the pollen type, the volatile compounds, and the phenolic and mineral profiles of three Euphorbia propolis samples collected in Morocco and evaluate their antimicrobial activi...
Chemical characterization of almond varieties natives from Algarve region
Carreira, Luís; Neves, Alcinda; Marreiros, António; El-Guendouz, Soukaïna; Ângelo, Luís; Peres, Maria de Fátima; Pedro, Soraia; Anjos, O.Almond, Prunus dulcis (Miller) D.A. Webb, syn. Prunus amygdalus Batsch is an important crop due to its fruits with high comercial value. In Portugal, there are traditional orchards in which almond trees grew on marginal soils, rainfed and with consequent low productivity; more recently huge investments in modern orchards with varieties originally from France and Spain such as ‘Ferraganés’, ‘Ferraduel’, ‘Guara’,...
Antioxidant activity and enzyme inhibitory potential of Euphorbia resinifera an...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Estevinho, Leticia M.; Paula, Vanessa B.; Aazza, Smail; El Ghadraoui, Lahsen; Rodrigues, Brígida; Raposo, SaraNatural products may be applied in a wide range of domains, from agriculture to food and pharmaceutical industries. In this study, the antioxidant properties and the capacity to inhibit some enzymatic activities of Euphorbia resinifera and Euphorbia officinarum aqueous extracts and honeys were assessed. The physicochemical characteristics were also evaluated. Higher amounts of iron, copper and aluminium were de...
Comparative study of the antioxidant and enzyme inhibitory activities of two ty...
Boutoub, Oumaima; El-Guendouz, Soukaïna; Manhita, Ana; Dias, Cristina Barrocas; Estevinho, Leticia M.; Paula, Vanessa B.; Carlier, Jorge D.Honey is a natural food product very famous for its health benefits for being an important source of antioxidant and phenolic compounds. Euphorbia honeys obtained from different regions of Morocco were evaluated for their ability to inhibit acetylcholinesterase, lipoxygenase, tyrosinase and xanthine oxidase activities. Their antioxidant properties were evaluated using the: 2,2-diphenyl- 1-picrylhydrazyl (DPPH) ...
Physicochemical characterization and antioxidant activity of honey with Eragros...
Aazza, Smail; Elamine, Youssef; El-Guendouz, Soukaïna; Lyoussi, Badiâa; Antunes, Maria Dulce; Estevinho, Leticia M.; Anjos, Ofélia; Carlier, Jorge D.This study aimed to characterize the pollen and physicochemical profiles, and to evaluate the antioxidant capacity of six samples of Moroccan honey. The pollen grains of Eragrostis spp. were predominant in all samples (from a minimum of 46.58 ± 1.59% to 72.72 ± 2.43% as a maximum), exceeding the minimum (generally 45%) required for the monoflorality nomination of a honey sample, and suggestion a case of newly r...
