The Effect of Rootstocks on the Peel Phenolic Compounds of Clementine Mandarin (Citrus clementina)

Studies have shown that phenolic compounds are important in human health. The purpose of this research was to examine the influence of rootstocks on phenolic compounds. The content of individual phenolic compounds in fruits was determined by HPLC. Total flavonoids content was measured using colorimetric method. Free radical scavenging activity on stable DPPH radicals was also evaluated. HPLC analysis of the peel compounds extracted from Clementine mandarin allowed identification of 7 phenolic components. Hesperidin was the main component for all rootstocks. Among the six rootstocks examined, Flying dragon showed the highest content of phenolic compounds. As a result of our study, we can conclude that the rootstock can influence the quantity of phenolic compounds present in fruit.
