Cornelian cherry (Cornus mas L.) is one of the most valuable fruit plants in the family
Cornaceae Bercht. et J. Presl. It is a very ancient cultural plant in Ukraine known from times of
Kiev on Rus. It was widely used as a valuable food and medicinal plant. All parts of the plant
cornelian cherry were widely used in folk medicine for the prevention and treatment of many
diseases – scarlet, fever, anemia, diabetes, gastrointestinal, skin, and others.
Fruits and drugs obtained from them (decoctions, tinctures, teas, concentrates of fresh
and dried raw materials) exhibit antiscorbutic, general health-improving, tonic, astringent,
temporary hypotensive, diuretic effect. Fresh fruits are recommended in amount 10–12 g/day
for neurasthenia, common weakening, joint pains, infectious hepatitis and other. Chemical
composition of fruits of cornelian cherry is quite rich. Among active compounds, there are
flavonoids (anthocyanins, flavonols), tanins, triterpenoids, iridoids and so-called P-active
compounds. Fruits and other parts of plant are used as active antimicrobial remedy for
various ailments due to the high content of biologically active substances.
The aim of this study was to evaluate the antioxidant activity and phenolics content of
cornelian cherry cultivars, which are used for cultivation in Ukraine.
The fruits of 20 cultivars of cornelian cherry collected in the M.M. Gryshko National
Botanical Garden of NAS of Ukraine (NBG) were the objects of these investigations. The raw
material was collected in the period of full ripeness (September). Antioxidant activity (AOA)
was measured using three different photometric methods – DPPH, ABTS and FRAP. Total
phenolic content (TPC) was evaluated using Folin-Ciocalteu reagent assay.
The results for AOA (umol Trolox/g) determined by the DPPH method varied from 5.94
(Kozerog) to 16.56 (Kostia), ABTS method varied from 13.560 (Koralovyj Marka) to 33.96
(Semen), FRAP method varied from 8.45 (Koralovyj) to 22.49 (Kostia). The results for TPC
varied from 91.34 (Kozerog) to 289.79 (Bolgarskyj) mg/100g. There was recorded a positive
linear correlation between antioxidant activity and total phenolic content in the examined
plant material.
Obtained data has shown that investigated cultivars have a potent antioxidant activity
that can be used for further investigation and usage of cornelian cherry.
The results of our study have also shown that cornelian cherry is an important
traditional plant that deserves special attention for widespread growing in Ukraine due to its
high biochemical characteristics, as well as useful nutritional and medicinal properties. The
fruits of cornelian cherry are promising sources of biologically active substances.
Cornelian cherry fruits are a rich source of nutrients for human. Currently this plant is
less known and this new source can be potentially used as functional food or value added
ingredients in the future in our dietary system.

Keywords: cornelian cherry, cultivars, fruits, antioxidant activity, phenolics content.
