This study was conducted to analyse the free radical scavenging potential of callus obtained from nodal segments and leaf explants of Artemisia amygdalina Decne. The explants were inoculated on MS medium augmented with various concentrations of BAP, Kn, NAA and 2,4-D for callus induction. In this study, 12.42 g of callus developed from the leaf explant on MS (NAA 10 BAP 7.5 µM) and 8.81 g of callus developed from nodal explant on NAA 2 µM BAP 2 µM. Callus raised from both explants on all treatments seemed non-regenerative but BAP 2 µM produced 7.33 shoots and BAP 15 µM produced callus and 5 shoots per nodal segment. Callus was analysed for antioxidant activity via DPPH, riboflavin photoxidation and DNA damage assays. Methanol and aqueous extracts show more scavenging in DPPH, deoxyribose assay and in contrast, petroleum ether and ethyl acetate extracts show higher activity in riboflavin photoxidation assay. Tocopherol, ascorbic acid and BHT were used as controls.
