Objectives: To analyze the phytochemicals quantitatively and screening the antioxidant efficacy of methanol extracts of Elytraria acaulis plant extractby in vitro.Methods: The total phenols, flavonoids, and tannin contents analyzed by Folin-Ciocalteu method, aluminum chloride colorimetric and calculated asgallic acid equivalents/g (GAE/g) of dry weight. Free radical scavenging activity was screened using 1,1-diphenyl-2-picrylhydrazyl (DPPH), radicalscavenging activities, and ferric reducing power assay was also analyzed.Results: The total phenolic content of the aqueous leaf extract was 46.84 µg GAE/g of extract powder. Significantly similar levels of total flavonoid andtannin contents of the plant were 41.72 and 39.50 µg GAE/g, respectively. The plant extracts showed appreciable free radical scavenging activities atthe highest concentration of 400 µg/mL superoxide anion radical with IC values (107.7±1.081 µg/mL), and for DPPH and considerably high amountof radical scavenging activity was found with very low IC5050 values (4.3±0.88 µg/mL) compared with quercetin.Conclusion: The phenolic and flavonoid compounds provide substantial antioxidant properties which could be effectively used for pharmaceutical,nutraceutical as well as anti-inflammatory applications.Keywords: Phenols, Flavonoids, 1,1-diphenyl-2-picrylhydrazyl, Pharmaceuticals.
