Antioxidant activities of the ethanolic extracts of roots, twigs and leaves of common barberry (Berberis vulgaris L) and Croatian barberry (Berberis croatica Horvat) were studied. All the extracts were found to possess some radical-scavenging and antioxidant activities, as determined by scavenging effect on the DPPH free radical, reducing power and beta-carotene-linoleic acid model system. With the exception of the beta-carotene-linoleic acid test, antioxidant activity correlated well with the content of main plant antioxidants, phenols and flavonols, which suggests an important role of these compounds in overall antioxidant activity of investigated plant organs. The antioxidant activity varied mostly in relation to the organ, while no significant statistically differences were found between B. vulgaris and B. croatica. (C) 2010 Elsevier Ltd.
