Introduction: The objective of this study was to determine antioxidant potential of Garcinia atroviridis leaves and fruits extracts in vitro. Methods: Antioxidant activity was assessed using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays. Total phenolic content (TPC) of the extracts was estimated as gallic acid equivalent by Folin-Ciocalteau method. Proximate analysis was determined based on the Association of Official Analytical Chemists (AOAC) procedures. Results: Garcinia atroviridis leaves extracted at 100 C/15 min demonstrated the highest TPC value (21.21±0.28 mg GAE/mg) and was significantly different (p< 0.05) from that of leaves extracted at 60 C/6 h and 40 C/12 h. On the other hand, the fruit extracted at 60 C/6 h showed the highest TPC value (16.23±0.18 mg GAE/mg)(p< 0.05) compared to the fruit extracted at 40 C/12 h and 100 C/15 h respectively. The …
