Green and Innovative Extraction: Phenolic Profiles and Biological Activities of...
Pallarés, Noelia; Berrada, Houda; Ferrer, Emilia; Rached, Wahiba; Pinela, José; Mandim, Filipa; Pires, Tânia C.S.P.; Finimundy, Tiane C.Underutilized plant species such as Asteriscus graveolens (Forssk.) Less., Haloxylon scoparium Pomel, and Ruta chalepensis L. have been historically valued in traditional medicine for their potential health benefits. These species present an untapped source of bioactive compounds with significant applications in the food and pharmaceutical industries, including the development of functional foods and additives....
Detailed chemical composition and functional properties of Ammodaucus leucotric...
Ziani, Borhane E.C.; Rached, Wahiba; Bachari, Khaldoun; Alves, Maria José; Calhelha, Ricardo C.; Barros, Lillian; Ferreira, Isabel C.F.R.Edible Ammodaucus leucotrichus Cross. & Dur. and Moringa oleifera Lamarck are largely used in the Algerian Sahara. In this context, soluble sugars, fatty acids, organic acids, and tocopherols were characterized. Decoctions and hydroethanolic extracts were studied regarding their phenolic compounds by HPLC-DAD-ESI/MSn, and in-vitro cytotoxic, anti-inflammatory, and antibacterial activities were evaluated. Result...
HPLC-DAD-ESI-MS/MS screening of phytochemical compounds and the bioactive prope...
Rached, Wahiba; Barros, Lillian; Ziani, Borhane E.C.; Bennaceur, Malika; Calhelha, Ricardo C.; Heleno, Sandrina A.; Alves, Maria JoséZizyphus lotus L. (Desf.) has been widely used as a homemade ingredient to treat numerous diseases in Algerian folk medicine. In this context, decoction, infusion and hydroethanolic extracts were prepared from the branches, leaves, roots, and stem barks. The extracts were characterized regarding their phytochemical composition by HPLC-DAD-ESI/MSn and were assessed for in vitro bioactivity (cytotoxicity, anti-in...
Bioactive properties of the endemic algerian Myrtus nivelii Batt & Trab.: scien...
Rached, Wahiba; Bennaceur, Malika; Barros, Lillian; Calhelha, Ricardo C.; Heleno, Sandrina A.; Alves, Maria José; Carvalho, Ana MariaMyrtus nivelli ileaves are widely used in the Algerian folk medicine, due toits healthpromoting properties attributed to the phenolic composition. In this context, bioactivities of the aqueous extract and its organic sub-fractions (ethyl acetate and butanol) were evaluated with focus onantioxidant properties (free radicals’ scavenging activity, reducing power, inhibition of β-carotene blanching andlipid peroxid...
Phenolic profile and in vitro bioactive potential of Saharan Juniperus phoenice...
Ghouti, Dalila; Rached, Wahiba; Abdallah, Moussaoui; Pires, Tânia C.S.; Calhelha, Ricardo C.; Alves, Maria José; Abderrahmane, Lazzouni HamadiThe aim of this study was to characterize the individual phenolic profile and antioxidant, anti-inflammatory, cytotoxic, and antimicrobial activities of hydroethanolic and infusion extracts prepared from Algerian Saharan Juniperus phoenicea L. and Cotula cinerea (Del). The phenolic profile was determined using a liquid chromatograph coupled to a diode array detector and an electrospray ionization mass spectrometer...
Phytochemical analysis and assessment of antioxidant, antimicrobial, anti-infla...
Rached, Wahiba; Zeghada, Fatima Zohra; Bennaceur, Malika; Barros, Lillian; Calhelha, Ricardo C.; Heleno, Sandrina A.; Alves, Maria JoséTetraclinis is an unexplored genus recognized for its great bioactive potential that could be explored as a medicinal herb. The aim of this study was to evaluate the antioxidant, antibacterial, anti-inflammatory and cytotoxic properties of the aqueous crude extract and subsequent organic fractions of the Algerian medicinal plant T. articulata. Moreover, polyphenols were also fully profiled by liquid chromatogra...
Fingerprint of phenolic compounds in Osyris quadripartite Salzm. ex Decne. from...
Rached, Wahiba; Calhelha, Ricardo C.; Fernandes, Ângela; Carvalho, Ana Maria; Bennaceur, Malika; Marouf, Abderrazak; Barros, LillianMedicinal plants are known as being a rich source of bioactive components, which can be correlated with their biological effects. The present study focused on the valorization of the leaves of Osyris quadripartite Salzm. ex Decne. with recognized folk medicinal uses in some Africa countries, namely Algeria [1, 2]. Therefore, the aim was to perform a phytochemical characterization, regarding phenolic composition...
Detailed phytochemical characterization and bioactive properties of: Myrtus niv...
Rached, Wahiba; Bennaceur, Malika; Barros, Lillian; Calhelha, Ricardo C.; Heleno, Sandrina A.; Alves, Maria José; Carvalho, Ana MariaThe endemic Algerian myrtle, Myrtus nivelii Batt & Trab., was evaluated for its bioactive properties, such as antioxidant, anti-inflammatory, cytotoxic and antibacterial activities, and correlated with the individual phenolic compounds identified in its crude aqueous extract and subsequent organic fractions (ethyl acetate and butanol). Flavonols, such as myricetin, kaempferol and quercetin glycoside derivatives...
Phytochemical characterization and bioactive properties of Osyris quadripartita...
Rached, Wahiba; Calhelha, Ricardo C.; Fernandes, Ângela; Carvalho, Ana Maria; Bennaceur, Malika; Marouf, Abderrazak; Barros, LillianMedicinal plants are sources of bioactive compounds with recognized beneficial effects on human health. An example is Osyris quadripartita, also known as Osyris lanceolata, which is known for its traditional therapeutic properties in some African countries. The aim of the present study was to evaluate the antioxidant (free radical scavenging activity, reducing power and lipid peroxidation inhibition), antiinfla...
