[25] found that methanol is a more effective solvent for the extraction of phenolic compounds than water in the case of R. canina but obtained just the opposite for R. arvensis. Higher phenolic levels and antioxidant capacity were found in methanolic and/or ethanolic extracts of other plant species compared to water extracts by some authors [53–56]. Therefore in recent scientific studies, alcoholic extraction is more frequently used than water extraction to determine antioxidant properties of different plant materials [57–60].
