Electrophoretic Comparison of Anthocyanin Pigments in Eight Varieties of Sour Cherries

SUMMARY– Electrophoresis and paper chromatography were used to establish the identity and the relative pigment concentrations in eight varieties of sour cherries using the pigments of Montmorency cherries as standards: (1) Marasca Moscata, (2) Wczesna Z Prinn, (3) Del Nord, (4) Königliche Amarelle, (5) Triaux, (6) Schattenmorelle, (7) Marasca di Ostheim and (8) Flemish Red. It was found that all varieties contained cyanidin‐3‐gentiobioside and cyanidin‐3‐rhamnoglucoside as their major anthocyanin pigments. All varieties except Flemish Red contained cyan‐idin‐3‐monoglucoside as a minor component. A second minor component of cyanidin‐3‐diglycoside was found in Wczesna Z Prinn, Del Nord, Schattenmorelle and Marasca di Ostheim. In all cases, the major pigments were approximately in the same relative concentrations as previously found in Montmorency cherries.
