From: Phenolic composition of leaf and flower extracts of black cherry (Prunus serotina Ehrh.)
Content of total analysed phenolics in black cherry leaves and flowers (g/kg DW) using different extraction methods. Methanol, standard extraction for phenolics (60% MeOH); water, extraction with hot water (infusion); ethanol (liqueur, 40% EtOH). Different letters (a–c) indicate significant differences in phenolic contents between different treatments (p < 0.05) by Duncan’s multiple range test
