Present study aimed to investigate phytoconstituents, total phenolic and flavonoids content, antioxidant activity and biochemical composition of the leaf extract of Artemisia argyi L. Qualitative analysis was conducted using standard methods however, total phenolic, flavonoids content and antioxidant activity was assessed by Folin-Ciocalteu, aluminium chloride colourimetric method and 1, 1Diphenyl-2-picrylhydrazyl (DPPH) assay, respectively. Compositional analysis was carried out by Gas chromatography-mass spectrometry (GC-MS). The outcome of the qualitative analysis suggested the presence of flavonoids, phenols, terpenoids, steroids, saponins, tannins and flavones except for alkaloids and glycosides. However, total phenols recorded were 16.89, 7.45 and 3.63 mg gallic acid equivalent GAE/g; flavonoids 20.80, 7.13 and 2.42 mg quercetin equivalent QE/g and DPPH inhibition percent was 81.48, 65.62 and 57.78% from 1, 2 and 3 extraction, respectively. GC-MS analysis exposed the existence of ten biological compounds corresponding to 99.91% of the total extract. However, erucylamide (33.42%), 1-decene, 4-methyl(12.63%), myo-Inositol, (10.42%), α-Cadinol (9.13%) and 2pyrrolidinone (8.68%) were the major compounds with five minor compounds. It was concluded that the leaves of A. argyi contain biological constituents responsible for antioxidant properties which can be introduced as a natural antioxidant pharmacologically and as botanical alternative of synthetic chemicals. However further studies are required on identification of specific components responsible for such activities.
