Comparative assessment of the content of vitamin C and carbohydrates in the fruits of Ribes L. species
2025
Victoriia Solochenko
The features of the biochemical composition (i.e., content of ascorbic acid and carbohydrates) have been determined in ripe fruits of five Ribes species (i.e., R. aureum, R. nigrum, R. alpinum, R. tenue, and R. rubrum). The plants were grown for many years in the collection of the “Оlexandria” State Dendrological Park of the NAS of Ukraine. Among the studied species, the highest content of ascorbic acid (vitamin C) was recorded in R. nigrum fruits (185.4 ± 19.0 mg/100 g), while the lowest was in R. tenue fruits (8.8 ± 1.4 mg/100 g). The highest content of carbohydrates was recorded in R. aureum fruits (9.7 ± 0.6 %), while the lowest was in R. rubrum fruits (1.8 ± 0.1 %). Over 60 % of the total sugar content was represented by invert sugars – fructose prevails, and glucose was much less present. The obtained results have practical value and can be applied in plant breeding to obtain adapted interspecific hybrids and new promising varieties of the genus Ribes.
