The present study focused on the evaluation of the antioxidant properties and the determination of total phenols and flavonoids Spathodea campanulata P. Beauv by spectrophotometry. Quantitative analyzes of total phenols and flavonoids were determined from the linear regression equation of the calibration curve, that is plotted using gallic acid and quercetin respectively as standard. The highest content of phenols was measured in the hydro-ethanolic extract, with a value equal to 10.17 mgGAE/g DE. Likewise, the determination of the flavonoids revealed that the hydroethanolic extract contains a maximum of flavonoids, with a level of 22.43 mg EQ / g DE. The antioxidant properties were evaluated by two tests, namely the diphenyl-picryl-hydrazyl radical scavenging test (DPPH) and the reducing power test (FRAP) in comparison with ascorbic acid and BHT respectively used as reference molecules. The results obtained show that the antioxidant activity of the hydroethanolic extract is greater with the two tests than those of the aqueous and hexane extracts.
