Abstract

The present investigation assesses free radical scavenging action of aqueous extract of leaf of Delonix regia used in different in vitro models. The extract was subjected to qualitative and quantitative phytochemical screening. The extracts were utilized at 20, 40, 60, 80 and 100 µg / ml concentrations and radical scavenging activity was determined in terms of inhibition percentage, and the IC50 was likewise ascertained for every radical (using Ascorbic acid as the reference in the investigation). The study additionally revealed that aqueous extract of Delonix regia has high radical scavenging action in the different radical systems. Total phenolic content was 34.31 ± 0.169 mg Gallic acid equivalent (GAE) /g extract while flavonoid content was 55.765 ± 0.898mg Quercetin/g extract and total antioxidant capacity was 52.33 ± 1.443mg ascorbic acid equivalent. In conclusion, the antioxidant activity of Delonix regia aqueous leaf extract might be due to the high flavonoid and phenol content of the plant.
