Paper chromatograms of leaf extracts of five pear species and one interspecific F1 hybrid. All detectable spots—mostly polyphenolic compounds—are marked. Components used for identification are indicated by solid lines and are numbered. Spot size and, for some, color intensity are indicative of amounts present.
