In this study, some biochemical properties of '& Scedil;am' and 'G & uuml;nd & uuml;zbey' peaches were revealed and can be genetically distinguished from other Prunus species with the chloroplast DNA barcoding (cpDNA) method. Total phenolic contents were determined as 139.9 mg/100 g in the 'G & uuml;nd & uuml;zbey' genotype and 41.4 mg/100 g in the '& Scedil;am' genotype, while total flavonoid contents were determined as 9.5 mg/100 g and 2.4 mg/100 g, respectively. Chlorophyll a contents were determined as 1.13 mu g/g in the 'G & uuml;nd & uuml;zbey' genotype and 1.82 mu g/g in the '& Scedil;am' genotype; chlorophyll b value was determined as 0.86 mu g/g in the 'G & uuml;nd & uuml;zbey' genotype, 1.14 mu g/g in the '& Scedil;am' genotype and total carotenoid values were determined as 0.10 mu g/g, 0.44 mu g/g, respectively. The 'G & uuml;nd & uuml;zbey' genotype had 72.5% 2,2 '-Azino-bis-3-ethylbenzthiazoline-6-sulfonic acid (ABTS +) radical scavenging activity, 72.2% 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 281.4 mu mol Fe II/g ferric reducing antioxidant power (FRAP); '& Scedil;am' genotype had 64.2% ABTS radical scavenging activity, 55.2% DPPH radical scavenging activity and 169.3 mu mol Fe II/g FRAP. 'G & uuml;nd & uuml;zbey' and '& Scedil;am' peach genotypes were found in a group with Prunus mira, P. kansuensis, P. dulcis, P. bucharica, P. argentea, P. grayana, P. virginiana, and P. serotina species in the phylogenetic trees obtained using chloroplast (cpDNA) rbcL sequences.eninfo:eu-repo/semantics/closedAccessAntioxidantGenetic VariabilityPeachPhenolicPrunus Persica L.Article10.1007/s10341-025-01344-46732-s2.0-105006469311Q4WOS:001494999100002N/A
