Abstract. The purpose of the research was to study the content of ascorbic acid (vitamin C), pectin, bioflavonoids in the berries of black currant under conditions of the forest-steppe zone of the Altai Territory and to identify the sources of their increased content for use in breeding and processing. The objects of the research were blackcurrant varieties bred in the Lisavenko Research Institute of Horticulture of Siberia and other scientific institutions. The work was conducted in 2000–2016. The total content and component composition of bioflavonoids were determined by spectrophotometric and colourimetric methods in ethanol extracts of the fruits. The quantitative content of vitamin C was determined by indophenol titration with potentiometric indication; pectin substances were determined by the titrimetric method. Under conditions of the forest-steppe zone of the Altai Territory, the content of vitamin C in currant berries averaged 111.6 mg/100 g varying from 50.6 mg/100 g to 217.0 mg/100 g. The amount of soluble pectin in the wet weight of fruits varied within 0.4–2.6% with an average value of 1.0%. The total content of pectin substances reached an average of 1.7% varying from 0.8% to 3.7%. The total content of bioflavonoids varied within 478.5–1013.8 mg/100 g, averaging 676.5 mg/100 g. We identified the most valuable varieties with a high level of studied characteristics. High vitamin C content was registered in the berries of Sadko, Lentyay, Dachnitsa, Lyubimitsa Bakchara, Seyanets Golubki, and Chernyy Aist varieties; high content of pectin substances was registered in Bariton, Lyubimitsa Bakchara, Zabava, Ekstrim, Lama, Garmoniya, Sofia, Natasha, Agata, Altaiskaya Pozdnyaya, Kanakhama, Ksyusha, Nika, Rita, Seyanets Golubki, and Ekzotika varieties; high content of bioflavonoids was registered in Zabava, Agata, Lama, Sokrovishche, and Garmoniya varieties; complex of biologically active compounds was registered in Lama, Seyanets Golubki, Lyubimitsa Bakchara, Agata, Garmoniya, and Sofia varieties.
