    • Chemical and biological properties of phenolics in wine: Analytical determinations and health benefits 

      Zúñiga López, María C.; Laurie, V. Felipe; Barriga González, Germán; Folch Cano, Christian; Fuentes, Jocelyn; Agosin Trumper, Eduardo; Olea Azar, Claudio (Bentham Science Publishers B.V., 2017)
      © 2017 Bentham Science Publishers. Since the early 1990s, a meaningful number of reports have been published supporting the idea that wines, especially reds, encompass a series of bioactive compounds, mainly phenolic ...
    • Estudio de resonancia de espín electrónico y estudio teórico de nuevas nitronas como atrapadores de radicales libres 

      Barriga González, Germán Eduardo (2013-01-04)
      Los radicales libres son por esencia especies reactivas que se encuentran involucradas en sistemas biológicos y químicos. Los radicales libres se encuentran presentes en la mayoría de las patologías existentes, ya sea ...
    • Evaluation of the Antioxidant Activity of the Flavonoids Isolated from Heliotropium Sinuatum Resin Using ORACFL, DPPH and ESR Methodologies 

      Barriga González, Germán; Chamorro, Eduardo; Salinas, Melissa; Modak, Brenda; Olea Azar, Claudio (Sociedad Chilena Química, 2016)
      The antioxidant capacity has been determined for a number of flavonoid compounds from Heliotropium sinuatum, a plant that grows in arid areas in the north of Chile. The methodologies used were: ORAC(FL) (oxygen radical ...
    • Nitrones: a potential new alternative as therapeutic agents 

      Barriga González, Germán Eduardo; Aliaga, Carolina; Olea Azar, Claudio; Zúniga López, María C.; González, Mercedes; Cerecetto, Hugo (Bentham Science Publishers Ltd., 2017)
      Background: Nowadays, nitrones are the most used spin traps to characterize free radicals in biological systems due to the versatility and variety depending on the types of radicals to study and that the half-lives of the ...
    • Spin Trapping: An Essential Tool for the Study of Diseases Caused by Oxidative Stress 

      Barriga González, Germán; Olea Azar, Claudio; Zúñiga López, María C.; Folch Cano, Christian; Aguilera Venegas, Benjamín; Porcal, Williams; González, Mercedes; Cerecetto, Hugo (Bentham Science Publ, 2015)
      Electron spin resonance (ESR), called also electron paramagnetic resonance (EPR) together with the spin trapping technique, has allowed us to study and understand how free radicals are involved in various pathologies. In ...
    • Synthesis and antioxidant study of new polyphenolic hybrid-coumarins 

      Pérez Cruz, Karina Angélica; Moncada-Basualto, Mauricio; Morales Valenzuela, Javier; Barriga González, Germán; Navarrete Encina, Patricio; Núñez Vergara, Luis; Squella Serrano, Juan; Olea Azar, Claudio (Elsevier, 2018-05)
      The antioxidant capacity of hydroxylated coumarins and hydroxybenzoic acids has been widely described. However, there is little information on the antioxidant activity when both systems are functionalized. In this work, ...
