Abstract :Antioxidant activities of the different extracts insert ignore into journalissuearticles values(n-heptane, chloroform, methanol); from the roots and aerial parts of Scorzonera veratrifolia by maceration method, as well as total phenolic and flavonoid content were examined first time in this study. The findings revealed that the methanol extract from S. veratrifolia aerial parts exhibited greater DPPH radical scavenging insert ignore into journalissuearticles values(IC50: 0.62±0.60 mg/mL); and iron insert ignore into journalissuearticles values(III); reduction capacity insert ignore into journalissuearticles values(1.56±0.03 mM Fe2+/mg extract);. Furthermore, aerial parts methanol extract has the highest concentration of total phenolic insert ignore into journalissuearticles values(46.3±1.1 mgGAE/g extract); and flavonoid insert ignore into journalissuearticles values(0.013±0.002 mg QE/mg extract); compounds. Based on these findings, the main phenolic content of aerial parts methanol extract was analyzed by LC-ESI-QTOF/MS, as this extract was found to contain the strongest antioxidant as well as the highest amount of phenolics and flavonoids as compared to the others. Quinic acid, chlorogenic acid, rutin, liquiritin, quercetin hexoside, luteolin-7-O-rutinoside, and di-O-caffeoylquinic acid compounds were identified as major compounds in methanol extract. The findings showed that aerial parts of S. veratrifolia, rather than its roots, could be used as a source of antioxidants.
