Antioxidant potentials of Acanthus ilicifolius leaves from Southwest Coastal Region of Bangladesh

• Unveiling the antioxidant potential of Acanthus ilicifolius leaves from Bangladesh's southwest coast. • Ethanol extract emerges as a potent antioxidant. • Acetone extraction reveals abundant bioactive compounds in Acanthus ilicifolius leaves. • Solvent selection is crucial in unlocking the antioxidant potential of Acanthus ilicifolius leaves. This research delves into the antioxidant potential of Acanthus ilicifolius leaves harvested from the southwestern coastal region of Bangladesh. Four distinct solvents—methanol, ethanol, acetone, and ethyl acetate—were utilized to determine antioxidant activities. Initial phytochemical screening unveiled the existence of many secondary metabolites, including as flavonoids, phenols, alkaloids, and others. Total phenolic content, total flavonoid content, and total proanthocyanidin content were determined using quantitative analysis. The assessment of antioxidant activity was conducted using the 1,1-diphenyl-2-picrylhydrazyl…
