Evaluation of Pterospermum suberifolium L. Willd Leaves for the Phytochemical Constituents and their in vitro Activities
The present study was intended to investigate the phytochemical constituents present in the leaves of Pterospermum suberifolium L. WILLD and the in vitro antioxidant and antimicrobial properties of the various extracts prepared by different solvents including aqueous, methanol, ethyl acetate and hexane. The crude extracts were screened for the presence of various phytochemical constituents and the presence of phenols, tannins, flavonoids, saponins and alkaloids were ascertained. The quantitative estimation of phenols and flavonoids were determined. The antioxidant activities of the plant leaf extracts were determined by the DPPH assay, the Phosphomolybdenum assay and the Nitric oxide scavenging assay. It was found that methanolic leaf extract of P. suberifolium possessed high antioxidant activity and found to have potential phytochemical constituents.
