| Abstract: | Anthocyanin extracts of two blueberries, Vaccinium myrtillus (bilberry)and Vaccinium ashei (rabbiteye blueberry), and ofthree other berries, Ribes nigrum (blackcurrant), Aronia melanocarpa (chokeberry), andSambucus nigra (elderberry), were analyzed by high-performanceliquid chromatography coupled withphotodiode array detection and electrosprayionization - mass spectrometry(LC/PDA/ESI-MS). Both bilberry and rabbiteyeblueberry contained 15 identical anthocyanins withdifferent distribution patterns. Black currant,chokeberry, and elderberry contained 6, 4, and 4 kindsof anthocyanins, respectively. The radicalscavenging activities of these berry extracts wereanalyzed by using 2,2-diphenyl-1-picrylhydrazyl(DPPH). All these extracts showed potent antiradical activities. |
