Abstract: Antioxidants are the compound that can prevent or inhibit oxidation which is a chemical reaction can produce free radical. Tabernaemontana divaricata plant has the ability to cure a variety of diseases with antioxidant capacity because of the presence of phytochemicals in it. The antioxidant activities of T. divaricata leaf aqueous extracts with different concentrations were investigate using DPPH assay, free radical scavenging activity, nitric oxide assay and superoxide radical scavenging activity. DPPH assay and nitric oxide assay shows higher values than free radical scavenging activity and super oxide antioxidant activity values for antioxidant capacity aqueous leaf extract of T. divericata. This novel study evident that aqueous extract of T. divaricata leaves may be exploited as an important source of antioxidants.
