The present investigation has been undertaken to study the preliminary phytochemical screening and antioxidant activity of Piper schmidtii leaf and stem. The different extracts such as petroleum ether, chloroform, ethyl acetate and ethanol were subjected for quantification (total phenolics, tannin, flavonoids) and in vitro antioxidant assay such as DPPH, Phosphomolybdenum, Superoxide radical scavenging assay and reducing power assay. Among the various solvents, ethanol extract of leaves displayed maximum total phenolic (267.86 mg GAE/g extract), tannin (250.14 mg GAE/g extract) and flavonoid contents (294.04 mg RE/g extract). Results of in vitro antioxidant studies revealed that the ethanol extract of leaf possessed an efficient 2,2-diphenyl-1-picryl-hydrazyl (DPPH•) (IC50 15.09 µg/mL), Phosphomolybdenum (52.93 mg AAE/g extract), superoxide (64.64%) radical scavenging activities and Reducing power possesses higher activity. Therefore, the results indicate that the leaf of Piper schmidtii can serve as a potential preliminary phytochemical and antioxidant activity.
