This study aimed to identify promising candidates of rowanberry cultivars for a wider
cultivation and utilization. Antioxidant properties and phenolic content were evaluated for fruit,
juice, and pomace samples of 16 different sweet rowanberry cultivars (cvs) and wild rowanberry
(S. aucuparia L.), while the antioxidant potential was assessed using three different methods, based
on the capacity to scavenge ABTS + and DPPH and measure the oxygen radical absorbance capacity
(ORAC). In general, the radical scavenging capacity was higher for hybrid cultivars, e.g., for cvs
Likernaja, Burka, Granatnaja, and Rubinovaja in all assays. The highest value in the ABTS + assay
was determined for the fruit sample Likernaja, and in DPPH assay in the pomace sample of cv.
Likernaja, at 527.55 and 1068.28 M TE/g dw, respectively. The highest ORAC value was found in
the fruit sample of Burka (456.53 M TE/g dw). Among the Nevezhino rowans, the highest radical
scavenging values of all fractions were determined in cv. Solnechnaja. Regarding the total phenolic
content (TPC), higher values were obtained in the whole fruits than in separated fractions, juice, and
pomace. The tested hybrids had higher TPC values, either in fruit and pomace or in juice extracts,
than those in the other analyzed S. aucuparia L. cultivars. While the fruit and juice samples showed
higher anthocyanin (ACY) values, the pomace samples had higher hydroxycinnamic acid (HCA)
contents on average. The results revealed that the different fractions of selected rowanberry cultivars
can be a promising source of antioxidants and polyphenols for further potential applications. It
is envisaged that the results of this study will serve in valorizing sweet rowanberry cultivars as
value-added functional ingredients for food and non-food applications.
