Herbs have been used for medicinal purposes for centuries. According to recent investigations, they may help reduce the risk of chronic diseases, cardiovascular disease, and cancer due to antioxidant properties, which in turn can be attributed to the various phytoconstituents. With this intention, evaluation of antioxidant activity was performed. Methanol extract of aerial parts of Artemisia pallens Wall was screened for its antioxidant activity due to phenolic and flavonoid contents, by employing radical scavenging assays; 2,2 -diphenyl, 1-picryl hydrazyl (DPPH) and nitric oxide. Ascorbic acid was used as a standard. Quantitative determination of phenols and flavonoids were carried out using spectrophotometric method. Total flavonoid content was determined as quercetin equivalent and total phenolic content was determined as pyrocatechol equivalent using Folin-Ciocalteu reagent. Plant produces more phenolic compounds than flavonoids. IC 50 value of methanol extract for DPPH free radical scavenging activity was found to be 292.7 μg, whereas for nitric oxide it was 204.61 μg. The result obtained in the present study indicates that the aerial parts of this plant are a rich source of natural antioxidants
