Dynamics of Phloridzin and Related Compounds in Four Cultivars of Apple Trees during the Vegetation Period.

ABSTRACT: Apple trees (Malus domestica Borgh) are a rich source of dihydrochalcones, phenolic acids and flavonoids. Considering the increasing demand for these phytochemicals with health-benefitting properties, the objective of this study was to evaluate the profile of the main bioactive compounds-phloridzin, phloretin, chlorogenic acid and rutin-in apple tree bark, leaves, flower buds and twigs. The variety in the phenolic profiles of four apple tree cultivars was monitored during the vegetation period from March to September using chromatography analysis. Phloridzin, the major glycoside of interest, reached the highest values in the bark of all the tested cultivars in May (up to 91.7 ± 4.4 mg g-1 of the dried weight (DW), cv. 'Opal'). In the leaves, the highest levels of phloridzin were found in c
