    • Honeybee pollen from southern Chile: phenolic profile, antioxidant capacity, bioaccessibility, and inhibition ... 
      Bridi, Raquel; Echeverría, Javier; Larena, Arturo; Núñez Pizarro, Paula; Atala, Elías; Costa De Camargo, Adriano; Oh, Won Young; Shahidi, Fereidoon; García, Olga; Ah-Hen, Kong S.; Montenegro, Gloria (Frontiers Media, 2022)
      Honeybee pollen (HBP) chemical composition is highly variable conforming to the floral and geographical origin of the pollen grains. The beneficial effects and functional properties of the HBP are well-known and have been ...
    • International Regulations of Propolis Quality: Required Assays do not Necessarily Reflect their ... 
      Bridi, Raquel; Montenegro, Gloria; Núñez Quijada, Gabriel; Giordano, Ady; Morán Romero, María Fernanda; Jara Pezoa, Isaac; Speisky Cosoy, Hernán; Atala, Elías; López Alarcón, Camilo (Institute of Food Technologists, 2015)
      Propolis has been proposed as a polyphenolic-rich natural product potentially able to be used for human consumption or even for medicinal proposes. To guarantee a minimum phenolic and flavonoid content and as consequence ...
    • Redox-implications associated with the formation of complexes between copper ions and reduced or oxidized ... 
      Aliaga, Margarita E.; López Alarcón, Camilo; Bridi, Raquel; Speisky Cosoy, Hernán (Elsevier, 2016)
      Binding of copper by reduced glutathione (GSH) is generally seen as a mechanism to lower, if not abolish, the otherwise high electrophilicity and redox activity of its free ions. In recent years, however, this concept has ...
    • Soluble free, esterified and insoluble-bound phenolic antioxidants from chickpeas prevent cytotoxicity in ... 
      Costa de Camargo, Adriano; Álvarez Larraín, Alina Concepción; Arias Santé, María Fernanda; Oyarzún, Juan Estebán; Andia, Marcelo E.; Uribe, Sergio; Núñez Pizarro, Paula; Bustos, Simón M.; Schwember, Andrés R.; Shahidi, Fereidoon; Bridi, Raquel (MDPI, 2022)
      Chickpeas are rich sources of bioactive compounds such as phenolic acids, flavonoids, and isoflavonoids. However, the contribution of insoluble-bound phenolics to their antioxidant properties remains unclear. Four varieties ...
    • Use of Pyrogallol Red and Pyranine as Probes to Evaluate Antioxidant Capacities towards Hypochlorite 
      Pérez Cruz, Fernanda; Cortés, Constanza J.; Atala, Elías; Bohle, Pamela; Valenzuela, Francisco; Olea Azar, Claudio; Speisky Cosoy, Hernán; Aspée, Alexis; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo; Bridi, Raquel (2013)
      Hypochlorite is a strong oxidant able to induce deleterious effects in biological systems. The goal of this work was to investigate the use of PGR and PYR as probes in assays aimed at evaluating antioxidant activities ...
