Abstract: Blueberry fruits from four commercial cultivars grown under same conditions at the same location were analyzed for total phenolics (TP) DPPH radical scavenging activity and superoxide radical scavenging ability (SRSA). The results demonstrated that all tested blueberries extracts showed very good antioxidant activity with dose-effect dependent, and the positive correlation among the content of total phenolics and antioxidant activity were also observed.

Key words: blueberry, polyphenol, antioxidation
