Sprib. and R. capitulatus Utsch.). All the studied extracts (methanolic, water, methanolic-water) showed high DPPH free radical scavenging activity (IC50 450.0-186.0 μg/ml). The most effective of the studied species was Rubus kuleszae. Total content of phenolic compounds (70.50-136.04 mg GAE/g) and phenolic acids (14.70-38.26 mg CAE/g) was determined spectrophotometrically. Antioxidant activity correlated positively with total content of phenolic compounds and phenolic acids.}, type={Artykuły / Articles}, title={Dpph Radical Scavenging Activity and Phenolic Compound Content in Different Leaf Extracts from Selected Blackberry Species}, URL={http://sp.czasopisma.pan.pl/Content/81767/PDF/v10182-012-0017-8.pdf}, doi={10.2478/v10182-012-0017-8}, keywords={Rubus, blackberry, leaf extract, antioxidant activity, DPPH, phenolic compounds, phenolic acids}, }
