Objective: This study was aimed to isolate and investigate antioxidant activity of gallic acid in pods of jiringa (Archidendron jiringa [Jack] I.C. Nielsen).Methods: Pods of jiringa were extracted by maceration. Phenolic compounds were tested using FeCl3. Identification of pure compound was obtained from spectra data from nuclear magnetic resonance of proton H (1H NMR), NMR of carbon (13C NMR), infra-red, and mass spectrometry. Antioxidant activity was investigated using 1,1-diphenyl-2-picrylhydrazyl method.Results: The IC50 of gallic acid from jiringa’s pods (A. jiringa [Jack] I.C. Nielsen) was 3.65 μg/ml. This value showed that gallic acid from jiringa’s pods (A. jiringa [Jack] I.C. Nielsen) had high antioxidant activity.Conclusions: Gallic acid presents in pods of jiringa (A. jiringa [Jack] I.C. Nielsen) and has high antioxidant activity.
