Sažetak
Young seedlings of wheat (Triticum aestivum L.) that can be used as a dietary supplement, are called wheat grass. Its juice is rich in chlorophylls, phenols and other antioxidant components, which is why it is considered a functional food. Chlorophyll is a rich source of bioavailable magnesium bounded to the porphyrin core in a similar way as iron is bounded to the hemium structure. Phenolic compounds are secondary metabolites of plants with high antioxidant activity. The aim of the research was to determine whether there are differences in the content of chloroplast pigments and phenols in wheat grass in five Croatian, five Hungarian and five Serbian cultivars, grown under controlled conditions. The highest ratio of chlorophyll a/b is found in Croatian and Hungarian cultivars in comparison to Serbian cultivars, and the highest average content of phenols was found in the group of Croatian cultivars. In all fifteen examined cultivars, the highest content of chlorophylls and carotenoids was found in the cultivar Žitarka, and the highest content of phenols in the cultivar Srpanjka. The highest content of chlorophylls and carotenoids in the group of Hungarian cultivars was found in the Chardas cultivar, and phenols in the cultivar MV Emese. In the group of Serbian cultivars, the Pesma cultivar was characterized by the highest content of chloroplastic pigments, while the highest content of phenols was found in the Sremica cultivar. The data obtained show that even in young seedlings of wheat, the specifity in chloroplastic pigments and phenols content is highlited and the correct selection of cultivar for domestic growing of this functional dietary supplement, is very important.
