Abstract
The objective of the present study was to evaluate photochemical screening, and estimate total phenol, total flavonoid, and antioxidant potential of the flowers extract of Peltophorum pterocarpum by DPPH radical scavenging assay. Total phenolic and flavonoid contents were evaluated according to Folin-Ciocalteau procedure and a calorimetric method, respectively. It showed high content of total phenolic compounds and total flavonoids. In vitro antioxidant activity of petroleum ether, chloroform, acetone, aqueous and ethanol extracts was evaluated by studying 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity using the standard procedure. The result shows that acetone extract of P. pterocarpum flowers had highest antioxidant activity (93.5%) using DPPH method.
