Abstract: The present study was undertaken for phytochemical analysis and evaluation of DPPH free radical scavenging activity of different extracts (acetone, ethanol and aqueous) of leaves, stem-bark, roots and fruits of bael. The results revealed that the extract yield of ethanol extracts of different parts of bael was highest (ranged from 9.18 to 37.42 g/100g) followed by aqueous extracts (ranged from 2.65 to 35.40 g/100g) and acetone extracts (ranged from 1.03 to 7.86 g/100g). Total phenolics content in aqueous extract was highest (ranged from 9.05 to 49.00 mg GAE/g) followed by ethanol extract (ranged from 3.21 to 13.32 mg GAE/g) and acetone extract (ranged from 0.62 to 3.75 mg GAE/g). Total flavonoids contents in aqueous extracts was highest (ranged from 2.14 to 11.89 mg CE/g) followed by ethanol extract (ranged from 1.49 to 4.37 mg CE/g) and acetone extract (ranged from 1.14 to 4.31 mg CE/g). DPPH free radical scavenging activity of bael extracts varied widely and it increased with increase of concentration levels. All the parts of bael were found to be rich source of antioxidants and exhibited better DPPH free radical scavenging activity in aqueous extracts in comparison to ethanol and acetone extracts.
