Abstract: In this work, phytochemical screening, total phenolic and flavonoid content, and antioxidant properties of methanolic extracts of leaves from three plants each of Abroma augusta,Abutilon indicum, andAcalypa Indica, as well as rhizomes and tubers from two plants each ofAlpinia galangal and Amorphophallus paonifolius, were determined. The 1,1-diphenyl,2-picrylhydrazyl (DPPH), hydroxyl radical(OH-), superoxide radical(O2-), and hydrogen peroxide(H2O2) assays were used to measure antioxidant properties, while the phosphomolybdenum assay was used to measure overall antioxidant activity. The analysis revealed that methanol was used to extract five plant sections into powder, resulting in 24.42 %, 25.93%, 24.13 %, 21.93 %, and 22.67%, respectively. The total phenolic contents of the five plant extracts were 12.82± 0.09 mg/g, 11.89 ±0.13 mg/g, 93.69± 0.14 mg/g, 13.29 ±0.09 mg/g, and 18.79± 0.21 mg/g, respectively, in dry weight. The extracts' respective total flavonoid concentrations were 9.27± 0.003 mg/g, 7.69 ±0.02 mg/g, 27.24± 0.04 mg/g, 8.43 ±0.02 mg/g, and 9.89 ±0.06 mg/g dry weight. The plant sample has a high capacity to scavenge free radicals and contains phytochemical elements that may prove valuable in future research to combat oxidative stress.
