In this paper, the phytochemical analysis revealed in the crude extracts of Aerva javanica plant the presence of different types of chemicals like flavonoids, tannins, alkaloids, saponins and phenols. This study was carried out to evaluate flavonoids and phenols content of stems and flowers extracts using solvents chloroform, ethyl acetate and n-butanol and which gives six extracts. Highest phenolic content (100.82±1.47 mg GAE /g extract) for ethyl acetate stems extracts, while highest flavonoid content (101.46±0.09 mg QE /g extract) for chloroform flowers extracts. The antioxidant activity was investigated by DPPH radical scavenging activity assay and phosphomolybdenum assay. It was observed in the same trend that the correlation between the total phenolic contents and total flavonoids achieved the best results. Chloroform flowers extracts had the highest free radical scavenging activity with IC50 of 0.1035±0.03mg/ml. In addition to phosphomolybdenum has achieved the highest result (67.72 mM) for n-butanol as compared to other solvents. The extracts from Aerva javanica (Burm. f.) exhibit good antioxidant activity.
