The antioxidant contents of the plants were determined using the CUPRAC, FRAP, and DPPH methods. The total phenolic content was determined using the Folin–Ciocalteu method, the phenolic compound profile was analyzed by HPLC, and the antimicrobial activity was assessed using the liquid microdilution method. The total polyphenol content was found to be 27.65 ± 1.12 mg GAE/g sample in the fruit of the plant with the highest amount, while the total flavonoid content was 15.13 ± 0.92 mg quercetin/g sample in the leaf part of the plant with the highest amount. Chlorogenic acid was identified as the major component in the fruit and leaf of B. vulgaris with concentrations of 1,195.56 ppm and 1,113.46 ppm, respectively. Catechin was identified as the major component in the seed part with a concentration of 130.29 ppm. B. vulgaris is a valuable source of bioactive phytochemicals with high functional quality. https://www.degruyter.com/document/doi/10.1515/znc-2024-0163/htmlinfo:eu-repo/semantics/embargoedAccessAntimicrobial activityAntioxidant acitivityBerberis vulgarisPhenolic composition10.1515/znc-2024-01632-s2.0-85214131975Q2WOS:001386258900001Q4
