Antioxidant Potential, DNA Protection, and HPLC-DAD Analysis of Neglected Medicinal Jurinea dolomiaea Roots
Jurinea dolomiaea Boiss., family Compositae, is a medicinally important plant of alpine region. Its tuberous roots are used in various ailments in folk medicine. This study was undertaken to estimate total phenolic (TPC) and total flavonoid contents (TFC) and to determine anti-free radical potential...

Jurinea dolomiaea Boiss., family Compositae, is a medicinally important plant of alpine region. Its tuberous roots are used in various ailments in folk medicine. This study was undertaken to estimate total phenolic (TPC) and total flavonoid contents (TFC) and to determine anti-free radical potential by diverse in vitro antioxidant assays. Crude methanol extract (JDME) was fractionated into n-hexane (JDHE), chloroform (JDCE), ethyl acetate (JDEE), n-butanol (JDBE), and aqueous (JDAE) fractions. The results indicated that JDEE and JDCE constituted the highest amount of TFC (807±7.2 mg rutin equivalent/g sample) and TPC (757±9.4 mg gallic acid equivalent/g sample), respectively. Significant correlation of TFC with IC50 values was recorded for •OH (R2=0.91), H2O2 (R2=0.82), and ABTS (R2=0.82) assay.
