Corn (Zea mays L.) with dark-colored grains accumulate anthocyanins - pigments from the class of flavonoids, which are products of secondary metabolism and have antioxidant properties. Numerous epidemiological studies have shown that consuming foods rich in anthocyanins leads to a significant reduction in diabetes, obesity, cardiovascular and oncological diseases. Participating in metabolism, anthocyanins have a beneficial effect on maintaining health. Based on this, the present study was evaluated the total content and composition of anthocyanins in the grains of 21 local dark corn samples. For this purpose, reversed-phase high-performance liquid chromatography (HPLC) with spectrophotometric and mass-spectrometric detection was used. In the grains of the studied forms, mainly cyanidin-3-glucoside and pelargonidin-3-glucoside, as well as isomeric products of their mono- and diacylation with malonic acid, were identified. Pelargonidin-3-glucoside derivatives predominated in the grain extracts of some studied forms. Promising corn samples were selected as a source material for further breeding work to create local forms with improved nutritional and therapeutic properties.
