Abstract
The aim of this study was to determine the mineral content of Cornelian cherry (Cornus mas L.), as this fruit and its preservatives may be considered as important nutritional supplements. Potassium (K), calcium (Ca), sodium (Na), iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) were present in Cornelian cherry juice as measured by atomic absorption. Compared to other juices obtained from plum, pear, and apple, Cornelian cherry juice contained high levels of Ca, reaching 10-fold higher (323 mg/L) levels than other juices (14–77 mg/L). With respect to the remaining elements, K, Na, Fe, Zn, and Mn, the levels noted for Cornus mas juice were also higher than in other juices studied. The reverse was true for Cu, for which levels were lower. Data indicate that Cornelian cherry juices are rich in various essential elements and might be considered as an important dietary mineral supplementation for individuals deficient in nutritional elements.
We thank two technicians, Ewelina Gajdzik and Barbara Tatar, for help in preparation of samples for investigations.
