This study primarily aims to evaluate antioxidant activity of red jabon (Anthocephalus macrophyllus) bark using DPPH (1, 1-diphenyl-2-pikrilhydrazyl). Result of this study shows that consentration level of IC₅₀ ethanol extracted red Jabon bark is about 2.545 ppm, indicating low antioxidant activity.
