This study analyzed the kinetics of antioxidant activity (AA) in ethanolic extracts (EE) and phenolic fractions (FFs) of Yacón infusions, a plant with antioxidant, anti-inflammatory and endothelial damage-reducing properties. The FFs were separated by chromatography (Sephadex® LH20), quantified (Folin-Ciocalteu) and analyzed by UHPLC-ESI+ ORBITRAP-HRMS. The kinetics of DPPH• radical reduction was modeled in COPASI v.4.44. The FF with 20% ethanol presented the highest content of CFs (311,394 µg EAG/mL) and AA, in whose fraction compounds such as caffeic, rosmarinic, epigallocatechin gallate and trans-cinnamic acids were identified, related to the neutralization of radical and non-radical EROI.
