The authors confirmed that the level of rosmarinic acid in the extracts was higher than that for caffeic acid. The highest level of rosmarinic acid was observed in ethanol extracts, lower concentrations of this acid were found in acetone and isopropanol extracts. Caffeic acid levels, in turn, were at similar levels irrespective of the solvent used. The presence of flavones (apigenin and luteolin) was additionally noted in acetone extracts
