Berry fruit leaves are recognized as potential medicaments which are rich
in different phenolic compounds, and have been used in folk medicine for centuries. In
order to evaluate phenol composition of fruit leaves from red currant (Ribes rubrum)
and black currant (Ribes nigrum) species were subjected to the spectrophotometric and
HPLC analysis. The antioxidant activity was estimated using DPPH free radical
scavenging assay. Flavonols, flavan-3-ols and phenolic acids were the main phenol
classes found in the investigated leaf extracts. Investigated extracts showed significant
antioxidant activity and a correlation with total phenol content. Ribes leaf extracts, rich
in phenolic content, with significant antioxidant activity, can be used as medical
supplements.
