In this study, the antioxidant and antimicrobial activities of the water and ethanol extracts obtained from the fruit and leaves of Paliurus spina-christi Mill., in the city of Kahramanmaras, were investigated. The antioxidant activities of the extracts were determined using the CUPRAC, DPPH, and ABTS methods, and the results were evaluated by comparing them with those of BHT and Trolox, as standard substances. On the other hand, the antimicrobial activities of the plant extracts were identified using the agar well diffusion method. According to the CUPRAC method, the antioxidant activities of the plant extracts at a concentration of 800 µg/mL were found to be lower than those of the standard antioxidant substances. The DPPH radical scavenging activity of the ethanolic extract of the leaves of the plant was found to be higher than that of Trolox. In the ABTS method, the radical scavenging activity of the fruit of the plant was found to be high and close to those of the standard antioxidants. According to the data obtained from the agar well diffusion method, ethanol extracts obtained from fruit and leaf parts on all microorganisms except Pasteurella multicoda and Bacillus cereus bacteria have the highest zone diameter. The ethanol extract of fruit of the plant was found to be more effective in Pseudomonas aeruginosa, Klebsiella pneumoniae and Candida albicans.
