Cornelian cherry (Cornus mas L.) is a species native to various European and southwest
Asian countries. Its fruits are edible and can be consumed raw or in the form of jams,
beverages, pickles, and many other preserves. Additionally, they have been used as traditional
medicine. Although its fruits are proved to be the source of numerous beneficial components,
such as natural antioxidants and pigments, this species belongs to forgotten plants. Cornelian
cherry fruits contain many radical-scavenging components that provide protection against
harmful free-radicals and can act against gastrointestinal disorders, heart diseases or
diabetes.
The aim of this study was to evaluate the basic chemical composition and bioactive
potential of three new Ukrainian cultivars of Cornelian cherry fruits: Jubilejnyj Klymenko,
Pervenets, and Sulija. For this purpose, they were compared with selected registered
Ukrainian (Kostia, Ugolok) and Polish (Bolestraszycki, Szafer) cultivars. All fruits used for the
study were collected in 2018. Registered Ukrainian and Polish cultivars were provided by
Arboretum in Bolestraszyce (Poland) and new Ukrainian cultivars by Gryshko National
Botanical Garden in Kyiv (Ukraine).
The basic chemical composition, the content of polyphenols, anthocyanins, and iridoids
of each cultivar was compared. Content of vitamin C was determined by the
2,6-dichloroindophenol titrimetric method. Total phenolic content (TPC) was evaluated using
the Folin-Ciocalteu reagent assay. Antioxidant activity was measured using two different
spectrophotometric methods, DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS
(2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid).
The content of vitamin C varied from 31.99 to 63.18 mg/100 g. The results of
antioxidant activity (μmol Trolox/100 g) determined by the DPPH method varied from 13.80
to 31.85 and obtained by the ABTS assay varied from 21.35 to 37.57. The results of TPC (mg
gallic acid/100 g) varied from 168.79 to 445.71. This study determined the variability of all
chemical characteristics of fruits and showed that the new Ukrainian cultivars composition
can be compared with those previously registered. High vitamin C content, compared to
registered varieties, was determined for Jubilejnyj Klymenko (53.02 mg/100 g) and high
antioxidant activity (ABTS) of 30.66 and 30.31 μmol Trolox/100 g respectively for Pervenets
and Sulija.
The importance of collection, identification, and evaluation of genetic resources of plants
is significant in terms of designing their application. Thus, the results of the present study can
be helpful to select the most promising sources of bioactive compounds among this species
and support the antioxidant potential of the new Ukrainian cultivars of cornelian cherry fruits.
