The cultivation of Chinese jujube can be traced back 7,000 years to the Neolithic era, making it one of the oldest cultivated fruit plants in the world. In Romania, Chinese jujube can be found in nature, semi-spontaneously, in Jurilovca and Mahmudia in Tulcea County and Ostrov in Constanța County. This paper describes the genotypes of Chinese jujube (Ziziphus jujuba Mill.) found in the Dobrogea region, specifically in Jurilovca, Mahmudia, Bugeac, and Ostrov. The study focuses on the chemical analysis and mineral composition of seven local jujube genotypes from Dobrogea and five Chinese cultivars. In the analyzed jujubes, sugar content varied between 15.91% to 31.07%; dry matter varied between 19.50% and 39.00%; total polyphenols varied between 390 to 1,020 mg gallic acid/100 g, calcium varied between 6.29 and 47.95 mg/100 g.
