The results indicated that total polyphenols were highest in EAE followed by CHE. However, the free radical scavenging activity of CHE was higher than the other extracts with an IC<sub>50</sub> value of 53.26 µg/mL. Determination of quercetin, gallic acid and rutin showed antioxidant activity as positive controls in parallel experiments. Moreover, oxidation of linoleic acid was effectively inhibited by AE, EAE and CE which were too close to each other. Also, the CHE was more effective compared to the synthetic antioxidant BHT. It could be concluded that <em>Carthamus caeruleus</em> L growing wild in the Mediterranean regions and especially in Algeria has a potent antioxidant activity and could be evaluated as a starting point for further investigations.</span>}, number={2}, journal={Comunicata Scientiae}, author={Baghiani, Abderrahmane and Boumerfeg, Sabah and Belkhiri, Farida and Khennouf, Seddik and Charef, Noureddine and Harzallah, Daoud and Arrar, Lekhmici and Abdel-Wahhab, Mosaad Attia}, year={2010}, month={Dec.}, pages={128} }
