The attention paid by consumers to the lesser known fruits has recently been increased. These fruits have unusual flavors and qualities, and many of which are rich in antioxidant substances such as phenolics specifically anthocyanins. In the present study, biochemical and antioxidant properties of ber (Ziziphus spina-christi), azarole (Crataegus azarolus), raspberry (Rubus hyrcanus), and cornelian cherry (Cormus mas) fruits with varied pigmentation obtained from Iranian native populations were studied. Total phenolics and ascorbic acid contents varied among these populations. Raspberry had the highest total phenolics and ascorbic acid content with 454.7 and 143.2 ㎎?100 g-1 fresh weight, respectively. Consequently, it showed the highest total anthocyanin (182.6 ㎎ pelargonidin-3-glucoside equivalent 100 g-1 fresh weight) content and antioxidant activity (82.3% scavenged 1,1-diphenyl-2-picrylhydrazyl radical). While the levels of total soluble solids and total acidity was highest in cornelian cherry population (12.3 and 9.9%, respectively). Antioxidant capacity was highly correlated with total anthocyanin and total phenolics content (r² = 0.78 and 0.72, respectively), whereas linear correlation between total antioxidant capacity with ascorbic acid was lower (r² = 0.43). The present study showed that the native raspberry fruit is an extremely rich source of antioxidants in comparison with ber, azarole, and cornelian cherry.
