This study included twenty-three samples of minor fruit species and twenty-three plum cultivars. First of all, the pomological properties of the plum cultivars were assessed, where the cultivar 'Aphrodite' was determined as the cultivar with the biggest fruits (56.6 g). The selected nutritional properties were subsequently determined in all forty-six samples. The highest value of the total soluble solids in the plums was 27.3 % in 'Stanley' (Prunus domestica) and 26.1 % in 'Krasavica' (Sorbus aucuparia) in the minor fruits; the highest total content of ascorbic acid in the plums was 83.3 mg/100 g in 'Stanley' (P. domestica) and 622.9 mg/100 g in 'Krasavica' (S. aucuparia) in the minor fruits; the highest total phenolic content in the plums was 429.8 mg GAE/100 g in 'Fortune' (Prunus salicina) and 45.3 mg GAE/100 g in the minor fruits and 983.9 mg GAE/100 g in 'Vydubecký' (Cornus mas); the highest total flavonoid content in the plums was 291.5 mg CE/100 g in 'Fortune' (P. salicina) and 544.7 mg CE/100 g in 'Nero' (Sorbus melanocarpa) in the minor fruits, and the highest total antioxidant activity in the plums was 809.5 mg TE/100 g in the hybrid 'SLE2014/2' (P. domestica × P. salicina) and 849.8 mg TE/100 g in 'Amfora' (Lonicera edulis) in the minor fruits.
