Saskatoon berries (Amelanchier alnifolia Nutt.) scavenge free radicals and inhibit intracellular oxidation
چکیده انگلیسی
Two cultivars (Thiessen and Smoky) of Saskatoon berries (Amelanchier alnifolia Nutt.) possess free radical scavenging activities in a concentration-dependent manner, whereas Thiessen presented higher (p < 0.05) activity compared to Smoky due to its relatively abundant anthocyanin content. Total anthocyanin content significantly corresponded to free radical scavenging activities (p < 0.05). Solvent fractionation revealed that the free radical scavenging components, i.e., anthocyanin, predominantly occurred in the ethyl acetate and n-butanol extracted fractions, suggesting that active components are more likely to occur in glycoside forms. HPLC further confirmed the existence of cyanidin-3-O-galactoside and cyanidin-3-O-glucoside as leading anthocyanins in the Saskatoon berries. Furthermore, Saskatoon berries extracts from both cultivars suppressed peroxy-radical induced intracellular oxidation in a concentration-dependent manner without affecting cell viability. The obtained results provided useful information for the future application of Saskatoon berries in the nutraceutical industry.
