Sažetak
This study characterized the genetic variability of local pomegranate germplasm from the Slovenian and Croatian areas of Istria. The bioactive components and antioxidative and antimicrobial properties were also determined for ethanol and water extracts of different parts of pomegranate fruit, along with their preliminary nutritional characterization. Twenty-six different genotypes observed with microsatellite analysis indicate the great diversity of pomegranate in Istria. The pomegranate fruit ethanol extracts represented rich sources of phenolic compounds (meanexocarp, 23 mg GA/g ; meanmesocarp, 16 mg GA/g). The ethanol extracts of pomegranate exocarp and mesocarp showed the greatest antimicrobial activity against Candida albicans, Candida parapsilosis, Rhodotorula mucilaginosa, Exophiala dermatitidis and Staphylococcus aureus, as for the same water extracts against S. aureus and Escherichia coli. To the best of our knowledge, this study represents the first report of the characterization of pomegranate genetic resources from Istria at different levels, including the molecular, chemical, antimicrobial, and nutritional properties.
