This study aimed at chemical characterization of nutritional and functional properties of Goji berries (Lycium barbarum L.) grown in Macedonia. For that issue, various chemical components were included: mineral nutrients, total proteins, antioxidant activity, total phenolic content, fatty acids and lipid indices. Characteristics were compared to those of Lycium Chinese L. capsules. Compared to the RDA values recommended by the European Commission, it has been established that Macedonian Goji berry is a rich source of mineral nutrients (K, Cu, Mn, P, Fe, Mg and Zn) and proteins. Fatty acids profile was dominated by polyunsaturated, mainly n-6 acids. Very low concentrations of toxic elements compared to allowable values in berry fruits set by European Commission and TTHQ index demonstrated no risk for human health. The statistical approach using PCA allowed grouping of nutritional components and those with bioactive properties in 4 groups: (1) minerals and proteins; (2) fatty nutrients; (3) -fatty acids and (4) components with antioxidant activity. Overall, Goji (Lycium barbarum L.) has proved to be an effective natural dietary supplement.
