Polyphenolic composition and Antioxidant Effect of Aerial Parts and Roots Extracts from Scorzonera veratrifolia

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