The presented study provides important insights on the health properties of Prunus persica fruit related to their polyphenol and carotenoid profiles, antioxidant capacity and in vitro potential to inhibit enzymes relevant to type 2 diabetes (alpha-amylase, alpha-glucosidase) and obesity (pancreatic lipase) management. Such results have not been published so far. The study showed substantial differences in the chemical composition of peach fruit depending on the cultivar. At the same time, it demonstrated some common features of selected cultivars - the varieties with light flesh ('Spring Time'; 'Madison') were characterized by a high content of phenolic acids and flavonols, thus exhibiting high activity against alpha-amylase, while the yellow varieties with high content of carotenoids ('Harrow Diamond'; 'Harrow Beauty') showed high inhibitory activity toward porcine pancreatic lipase. Finally, it has been shown that peach fruit is an interesting raw material with a varied chemical composition and nutritional value, especially with high inhibitory potential against digestive enzymes linked to obesity and type 2 diabetes, strongly determined by the cultivar.
