The EC50 estimations of DPPH, FRAP, and ABTS free radical scavenging activities of the fruit extracts were performed using GraphPad Prism statistical model. The antioxidant activity was measured by the commonly accepted assays of 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and -diammonium salt (ABTS) while the EC50 values were ranged between 2.94 (Mundia, the minimum value) and 15.48 (Gola, the maximum value) mg/mL. A new statistical method approach, known as GraphPad Prism software, was used for the estimation and evaluations of fruit extracts in terms of EC50 values for the first time. Soxhlet methanolic extraction at 45 ☌ for about 4 h was used to extract the compounds from fruits. According to this study, Kunkura, Umaran, Gola, and Mundia fruits are important sources of minerals (Mg, K, Ca, Na, P, Fe, Zn, Mn, Cu, and Se) than common cereals and grains. This study aimed to examine total phenolic contents (TPC), total flavonoid contents (TFC), proximate, mineral contents, and the in vitro antioxidant potentials of the spina-christi (Ethiopian Kunkura/Gava) fruit as compared with Indian jujube (Ber fruits - Umaran, Gola, and Mundia) fruits. There are several underutilized and wild fruit species in Ethiopia that can be used as sources of human food consumption.
