Juglans neotropica Diels "peruvian walnut" is a tree that grows in jungle, in areas ofmontane and montane rain forest whose leaves have antioxidant, astringent, antibacterial andantiseptic properties. The objective was to determine the antioxidant activity of a standardizedhydroalcoholic extract of Juglans neotropica Diels leaves. Leaves from Huandoval district,Pallasca province, Ancash Region were used. Standardization analysis included determinationof moisture, physicochemical parameters, solubility march, phytochemical screening, andthin layer chromatography; antioxidant activity was determined by the DPPH inhibitionassay. In phytochemical screening there was a greater concentration of phenolic compoundsand antioxidant activity was at 25 and 35 μg/mL respectively, with an IC 50 of 12.82 μg/mL.In conclusion, the standardized hydroalcoholic extract from Juglans neotropica Diels leavesfulfilled the quality parameters, and showed high antioxidant activity.
