Abstract

Aim of the study was to evaluate antioxidant activity and total phenolic content of Echinops ritro L. and E. tournefortii (Asteraceae). The
dried leaves and seeds of E. ritro
and E. tournefortii were extracted separately with ethanol, methanol,
chloroform and dH₂O. Total phenolic content was measured by
Folin-Ciocalteu method. Antioxidant activities of the extracts were
determined by two test systems namely, radical scavenging on DPPH and β-carotene
bleaching methods. dH₂O extracts has the highest phenolic content (92.24 GAE
mg/100g). The results were compared to those of BHT as synthetic antioxidant. dH₂O
extracts were found to be rich as a source of phenolics. According to the results of antioxidant activity, dH₂O extracts exhibited higher
antioxidant activity than all types of solvent. The strongest antioxidant properties were obtained by dH₂O
extract. Radical scavenging activities (%) were found to be in the following
order: Chloroform<Ethanol<Methanol<dH₂O<BHT. These
results of the present study demonstrated that the extracts of E. ritro and E. tournefortii may be used as a source of natural antioxidant
in the food and pharmaceutical industries.
