“…Previous studies of the plum cultivars “Čačanska Lepotica”, “Stanley”, and “Jojo” grown in the experimental nursery of the Agricultural University near Plovdiv (Bulgaria) have shown a significant influence of “Wavit”, “Ishtara”, “GF-677”, and “GXN-15” rootstocks on the growth characteristics of the cultivars [ 11 ] and the content of macro- and microelements (K, Ca, Mg, Fe, Zn, Cu, Mn, and B) [ 12 ], while the content of sugars, polyphenols, anthocyanins, and organic acids in the fruit flesh was found to be more dependent on the genotype than on the rootstock [ 13 ]. The content of the individual phenolic compounds in the plum fruit of these cultivars and their antioxidant properties have not been studied yet.…”

We investigated the influence of different rootstocks on the content of sugars, organic acids, and antioxidant phenolic compounds in the whole fruit and fruit skin of the European plum cultivar “Čačanska Lepotica”. 1H NMR of the fruit extracts allowed for the identification of sucrose, α- and β-glucose, sorbitol, fructose, and malic and quinic acids, while LC–DAD–ESIMS showed the presence of neochlorogenic and chlorogenic acids, cyanidin-3-O-glucoside, cyanidin-3-O-rutinoside, peonidin-3-O-glucoside, peonidin-3-O-rutinoside, hyperoside, isoquercitrin, rutin, and unidentified quercetin-3-diglycoside. The quantitation of the sugars, malic and quinic acids by 1H NMR and phenolic compounds by HPLC–DAD revealed that the rootstock significantly influenced the content of the individual compounds in the fruit skin and fruit. The fruit grafted on “Wavit” rootstock was characterized by significant amounts of neochlorogenic acid, peonidin-3-O-rutinoside, cyanidin-3-O-rutinoside, and sucrose, while the fruit on “GXN-15” was characterized by high levels of sugars, cyanidin-3-O-glucoside, and malic and chlorogenic acids. The fruit skins of plums grafted on “Wavit” were the richest in sugars, organic acids, and phenolic compounds. A good correlation was observed between the content of total phenolics (TPC), flavonoids (TFC), anthocyanins (TAC), and individual phenolic compounds in the extracts of the fruit and the fruit skins and their antioxidant capacity (DPPH, ABTS, and FRAP).
