Súhrn: Azarole fruit (Mediterranean medlar, Crataegus azarolus L.) has attracted increasing attention in the field of functional foods because of its widely reported health benefits. The aim of this research was to describe overall quality traits of azarole fruit, report its antioxidant activity, and identify and quantify the levels of potentially bioactive compounds by chromatographic fingerprints. Different methods were used to determine concentrations of phytochemical compounds (phenolic and organic acids, flavonols, tannins, catechins, monoterpenes, vitamin C) in the fresh fruits. For the analysis, high performance liquid chromatography with diode-array detection was used. The same analytical methods were also applied to some common temperate fruit species grown in the same pedoclimatic conditions in order to understand if C. azarolus presents a real added phytochemical value compared with others. The chemical fingerprints showed the prevalence of organic acids (55.0%), followed by polyphenols (25.1%), monoterpenes (15.4%) and vitamins (4.5%) in the phytochemical composition of all the analysed samples (mean values were considered). This study developed an effective tool to assess azarole fruit quality, chemical composition and antioxidant activity. The results may support the exploitation of this fruit as a potential natural source of bioactive compounds in several applications.
