This study characterises the genetic variability of local pomegranate ( L.) germplasm from the Slovenian and Croatian areas of Istria. The bioactive components and antioxidant and antimicrobial properties of ethanol and water extracts of different parts of pomegranate fruit were also determined, along with their preliminary nutritional characterisation. Twenty-six different genotypes identified with microsatellite analysis indicate the great diversity of pomegranate in Istria. The pomegranate fruit ethanol extracts represent rich sources of phenolic compounds (mean value of the mass fraction in exocarp and mesocarp expressed as gallic acid is 23 and 16 mg/g, respectively). The ethanol extracts of pomegranate exocarp and mesocarp showed the greatest antimicrobial activity against , , , and , and the same water extracts against and To the best of our knowledge, this study represents the first report of the characterisation of pomegranate genetic resources from Istria at different levels, including the molecular, chemical, antimicrobial and nutritional properties.
本研究对来自斯洛文尼亚和克罗地亚伊斯特拉地区的当地石榴（L.）种质的遗传变异性进行了表征。同时还测定了石榴果实不同部位乙醇提取物和水提取物的生物活性成分、抗氧化和抗菌特性，以及它们的初步营养特性。通过微卫星分析鉴定出的26种不同基因型表明伊斯特拉地区石榴具有高度多样性。石榴果实乙醇提取物是酚类化合物的丰富来源（外果皮和中果皮中以没食子酸表示的质量分数平均值分别为23和16 mg/g）。石榴外果皮和中果皮的乙醇提取物对、、、和表现出最大的抗菌活性，而相同的水提取物对和表现出最大抗菌活性。据我们所知，本研究是关于伊斯特拉地区石榴遗传资源在分子、化学、抗菌和营养特性等不同层面表征的首份报告。
