In the current investigation, Careya arborea fruit pulp was used to assess total phenolic, flavonoid and in vitro antioxidant potential. The ethyl acetate extract (EAE), methanolic extract (ME), water extract (WE) of fruit pulp were studied. Using the Folin-Ciocalteau reagent, total phenolics were measured, and the colorimetric method was used to determine the flavonoid concentration. Antioxidant activity was evaluated using DPPH assay and reducing power by FeCl3. A positive control was ascorbic acid. The fruit pulps from C. arborea with the highest phenolic, flavonoid, and antioxidant potential were extracted using ethyl acetate. When compared to a positive control, the C. arborea fruit showed a substantial in vitro antioxidant activity (P < 0.05). The Finding concluded that the C. arborea fruit pulp exhibited antioxidant activity.
