The specialized literature presents multiple investigations into obtaining and eval-uating active principles from different plant sources. Researchers also have knowledge about the phytochemical composition of the leaves, fruits, and bark of the Ziziphus jujuba tree, but this information pertains to the plant grown outside the republic. Until now, researchers have not explored the cosmetic value of the active principles of Ziziphus ju-juba, despite its cultivation in the Republic of Moldova since 1975. The easy extraction method was used to obtain the active ingredients from the leaves and fruits by mixing them with a hydro-ethanolic solution that had different con-centrations (40%, 50%, 60%, 70%, and 80%) and letting the biomass mix with the solvent for different amounts of time (60, 120, and 180 minutes), all while the mixture was being stirred continuously. The total amount of phenols and reduction capacity of the phospho-molybdenum reagent were measured to assess the activity of the extracts. The extracts with the most phenols and antioxidant activity were made by using a hydro-ethanolic solution with a concentration of 50% ethanol and an extraction time of 180 minutes. The phenolic content is higher in leaves, varying between 0.06 and 0.15 mg GAE/g, compared to fruits, which have limits of 0.02 and 0.06 mg GAE/g. The results demonstrate that the Ziziphus jujuba biomass extract is low in polyphenolic compounds. The antioxidant capacity test revealed that the fruit extracts exhibited higher values (6.20 to 8.51 mg AAE/g extract) than the leaf extracts (4.04 to 5.90 mg AAE/g extract). The results of the study showed that Ziziphus jujube biomass extracts show anti-oxidant potential, but this is due to substances other than phenolic compounds.
