Atala, E.; Aspée, Alexis; Speisky Cosoy, Hernán; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo (2013)A novel ORAC (oxygen radical absorbance capacity) assay to assess antioxidant capacity of phenolic compounds in near-gastric conditions (pH 2.0) is presented. AAPH (2,2'-azo-bis(2-amidinopropane)dihydrochloride) was used ...

Atala, E.; Vásquez, L.; Speisky Cosoy, Hernán; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo (2009)An oxygen radical absorbance capacity (ORAC) method based on pyrogallol red bleaching (ORAC-PGR) was used to evaluate the scavenging activity of berry extracts (blackberry, blueberry, and raspberry). Among berry extracts, ...
