Abstract

The aim of this study was to determine the colour components (L*, a*, b*), soluble solid (SS), water and L-ascorbic acid contents in the fruit of ten different genotypes of cornelian cherry (Cornus mas L.) Fatty-acid composition, the total fat and ash and mineral contents were determined in the stones. The values of the colour components were: L* from 21.51 to 27.85, a* from 8.64 to 26.22, and b* from 2.15 to 11.90. They contained from 10.70 % to 19.30 % SS. The L-ascorbic-acid content ranged from 29.29 to 86.40 mg/100 g. The genotypes showed statistically significant differences according to the colour parameters and the content of soluble solids and L-ascorbic acid. In 100 g stones, there were from 5.82 to 6.73 g water, from 0.84 to 1.51 g ash, and from 4.45 to 7.94 g fat. For the fatty-acid composition, these were mainly represented by: linoleic acid from 64.78 % to 72.21 %; oleic acid from 15.50 % to 22.97 %; palmitic acid from 7.31 % to 8.11 %; stearic acid from 2.02 % to 2.99 %; linolenic acid from 1.47 % to 1.62 %; and arachidic acid from 0.27 % to 1.52 %. The genotypes showed statistically significant variations in the content of fatty acids with the exception of linolenic acid. 100 g of stones contained: calcium from 385.79 to 432.91 mg; potassium from 243.09 to 327.04 mg; phosphorus from 152.01 to 261.48 mg; magnesium from 39.38 to 56.68 mg; sodium from 13.22 to 19.40 mg; and copper from 0.39 to 0.81 mg.
