Fruits of Fagara budrunga was extracted with solvents of different polarities. Antioxidant activity of n-hexane, ethyl acetate and methanol extracts were determined in vitro by DPPH free radical scavenging assay,β -carotene bleaching assay and reducing power assays. BHT was used as the standard. The radical scavenging activity and reducing power of the extracts significantly decreased in the order methanol extract > ethyl acetate extract > n-hexane extract. A strong inhibition of lipid peroxidation in β-carotene bleaching assay was exhibited by n-hexane extract followed by ethyl acetate extract and methanol extract. The methanol extract was found to possess highest phenolic content (75 mg GAE/g dry weight) among the extracts. It is seen that the yield and activities of extract was affected by the solvent used for extraction. Phytochemical investigation of the extracts indicated the presence of alkaloids, flavonoids, tannins, steroids and terpenoids. The present study provides phytochemical screening results and evaluation of antioxidant activities of F. budrunga extracts.
