The purpose of this work was to study the qualitative and quantitative composition of the main groups of biologically active substances in the fresh fruits of five different varieties of black chokeberry (Aronia melanocarpa (Michx.) Elliot), carried out within the framework of the search for available and cost-effective raw materials for food product fortification. Samples of aronia chokeberry were grown at the Federal Scientific Center named after I.V. Michurin in the Tambov region of Russia. Using a modern chemical–analytical methodology, the contents and profiles of anthocyanin pigments, proanthocyanidins, flavonoids, hydroxycinnamic acids, organic acids (malic, quinic, succinic, and citric), monosaccharides, disaccharides, and sorbitol were determined in detail. Based on the results of the study, the most promising varieties were determined in terms of the content of the main biologically active substances.

Методом ВЭЖХ определено суммарное содержание и специфические профили индивидуальных антоцианинов плодов аронии черноплодной различных сортов. Хроматографические профили извлечений из всех сортов оказались сходны с преобладанием цианидин-3-галактозида в качестве основного ингредиента. Общее количество антоцианов составило от 0,98% (Алтайская крупноплод- ная) до 3,70% (Мичуринская).
