 "Prunus cerasus is thought to have originated as a natural hybrid between Prunus avium and Prunus fruticosa in the Iranian Plateau or Eastern Europe where the two species come into contact. Prunus fruticosa is believed to have provided its smaller size and sour tasting fruit. The hybrids then stabilised and interbred to form a new, distinct species."

-"The analysis results for seven of the aroma compounds obtained by vacuum distillation from sweet and sour cherry products were compared. The freshly pressed juices from 5 varieties of sour and 5 varieties of sweet cherries showed great differences in concentrations (μg/1): benzaldehyde (18393), linalool (0.51.7), hexanal (0.354.7), 2(E)-hexenal (2.4220), 2(E),6(Z)-nonadienal (0.12.4), phenylacetaldehyde (2.15.6) and eugenol (1.022.2). The benzaldehyde content of the juices showed the highest correlation to the recognition threshold of the cherry aroma note. The cherry jam showed a drastic change in the aroma composition: benzaldehyde and linalool increased greatly (7 and 13-times, respectively), while hexanal, 2(E)-hexenal and phenylacetaldehyde strongly decreased. The increase in benzaldehyde and linalool, which was also observed during simultaneous distillation/extraction of the juices, is caused by the hydrolysis of the corresponding glycosides during the heat treatments." \\+|{{:benzaldehyde.jpg|benzaldehyde}} \\ benzaldehyde |{{:ez26nonadienal.jpg|(E,Z)-nona-2,6-dienal}} \\ (E,Z)-nona-2,6-dienal |{{:phenylacetaldehyde.jpg|phenylacetaldehyde}} \\ phenylacetaldehyde |{{:eugenol.jpg|eugenol}} \\ eugenol |
