Prunus serotina Ehrh. - Rosaceae - black cherry, wild Cherry, American cherry, plum cherry, rum cherry, Spätblühende Traubenkirsche, Amerikanische Traubenkirsche
Prunus serotina var.serotina = black cherry, rum cherry (Canada, USA) Prunus serotina var.salicifolia = Prunus capuli Cav.; Prunus salicifolia Kunth: capulín (México)
Deciduous tree, up to 15m high, native to eastern North America, cultivated as ornamental, naturalized in Europe and South America; leaves alternate, thin, toothed; inflorescence a raceme; flowers whtie, about 1 cm across; fruit black-purple, up to 1.5cm, resembling a cherry.
„P. serotina was widely introduced into Western and Central Europe as an ornamental tree in the mid 20th century, where it has become locally naturalized. It has acted as an invasive species there, negatively affecting forest community biodiversity and regeneration… The fruit of Prunus serotina is suitable for making jam and cherry pies, and has some use in flavoring liqueurs; they are also a popular flavoring for sodas and ice creams. The black cherry is commonly used instead of sweet cherries (Prunus avium) to achieve a sharper taste.“

„…the essential oil obtained from the leaves of P.serotina promoted vascular smooth muscle relaxation. The
oil was analyzed by gas chromatography coupled to mass spectrometry and fifty seven compounds were detected. Four of the major constituents, benzyl alcohol (4)(20.3%), benzaldehyde (12.1%), cinnamyl alcohol (6) (4.7%), and cinnamaldehyde (7) (1.1%) also induced a concentration-dependent relaxation of rat aorta. The greatest vasorelaxant effect was observed for compound 6 (EC50=42.2±5.7μg/ml). The results derived from this study provide a scientific basis for the traditional use of the leaves of this plant for the treatment of hypertension.“
