Objective: Phytochemicals with antioxidant potential have great potential to control both plant and human diseases. Aim of this study is to analyse the assorted phytochemical constituents impact of various solvents on their extraction yields and further to determine the bioactive phytochemicals and amount of antioxidant activity of Alangium Salvifolium seeds. Methods: Seeds of Alangium salvifolium were obtained, screened for phytochemicals and evaluated for their antioxidant activity. Chemical analysis of phytochemical constituents were performed by standard protocols. Various in vitro methods have been used to test the antioxidant activity of plant extracts, such as the DPPH free radical scavenging assay and SOS activity. Results: Phytochemical screening of plant extracts evaluated, revealed the subsequent presence of bioactive components And antioxidant potential. The present study revealed that the ethanolic extract of seeds of Alangium salvifolium showed significant antioxidant activities. Conclusion: Alangium Salvifolium is a remarkable medicinal plant that has a variety of bioactive phytochemicals and can be used to prevent a variety of diseases. Recent research suggests that antioxidants derived from plants with free-radical scavenging properties may be useful in the treatment of free-radical-mediated chronic conditions.
