In Antioxidants are compounds possessing the capability to neutralize or stabilize free radicals. In general, plants from the Fabaceae family have antioxidant activity. The research aimed to determine the antioxidant activity of the Fabaceae family plant based on maceration extraction using the DPPH method as seen from IC50. The method used was the narrative review method, where the selected articles were based on inclusion and exclusion criteria and obtained from Google Scholar, PubMed and ScienceDirect databases published between 2011-2021. The results indicated that the Fabaceae family plants having the strong antioxidant activity based on IC50 were methanol extract of Indigofera cassioides leaf of 13.97 g/mL, methanol extract of Gogon Sirih (Albizia richardiana) bark of 17.8 g/mL, ethanol extract of vegetable hummingbird (Sesbania grandiflora) stem of 24.30 g/mL and ethanol extract of butterfly pea (Clitoriaternatea) of 41.36 g/mL. The strong antioxidants were found in methanol extract of blackbead (Pithecellobium jiringa) peel of 51.19 g/mL and acetone extract of vegetable hummingbird leaves of 56.57 g/mL; the medium antioxidant was in methanol extract of dadap (Erythrina subumbrans) bark of 189.57 g/mL; the weak antioxidants were in ethanol extract of old acacia (Acacia auriculiformis) leaves of 433.63 g/mL and ethanol extract of young acacia leaves of 464.23 µg/mL; the very weak antioxidant was found in ethanol extract of flame tree (Delonix regia) leaves of 4.030 g/mL.
