In this study we assessed the main bioactive compounds of a broad apple germplasm collection, composed by 247 accessions of wild (97) and domesticated (150) species. Among the stilbenes, trans- and cis-piceid were found to be ubiquitary components of both wild and cultivated apples. Apple was suggested to be the second dietary source of resveratrols. Results confirmed that the selection pressure of breeding and domestication did not affect uniformly all the phytochemicals contained in apple. For instance, organic acids (malic and ascorbic acid) and some phenolics (stilbenes, hydroxycinnamic acids, and dihydrochalcones) were significantly influenced by selection while some relevant flavonoids (flavonols and flavan-3-ols) and triterpenoids (ursolic, oleanoic, and betulinic acids) were not. This comprehensive screening will assist in the selection of Malus accessions with specific nutraceutical traits suitable to establish innovative breeding strategies or to patent new functional foods and beverages.

Abstract
In this study we assessed the main bioactive compounds of a broad apple germplasm collection, composed by 247 accessions of wild (97) and domesticated (150) species. Among the stilbenes, trans- and cis-piceid were found to be ubiquitary components of both wild and cultivated apples. Apple was suggested to be the second dietary source of resveratrols. Results confirmed that the selection pressure of breeding and domestication did not affect uniformly all the phytochemicals contained in apple. For instance, organic acids (malic and ascorbic acid) and some phenolics (stilbenes, hydroxycinnamic acids, and dihydrochalcones) were significantly influenced by selection while some relevant flavonoids (flavonols and flavan-3-ols) and triterpenoids (ursolic, oleanoic, and betulinic acids) were not. This comprehensive screening will assist in the selection of Malus accessions with specific nutraceutical traits suitable to establish innovative breeding strategies or to patent new functional foods and beverages.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
