dc.description.abstractPlants are being used for various purposes since ancient times and have an important place in improving human health. Studies have shown that plant components contain any phytochemical compounds with strong antioxidant and antimicrobial activity. Plants and their essential oils have been studied in number of research fields in terms of their antimicrobial and antioxidant effects, especially since 1940 and important results have been obtained. Hypericum perforatum L, also known as St. John's wort, is one of these medicinally important plants, traditionally widely used and recognized as a valuable herbal medicine for more than 2000 years. In this study, the antimicrobial properties and antioxidant capacity of H. perforatum L. (St. John's wort) were determined and compared with Hypericum malatyanum Pe & scedil;men, a species endemic to Malatya. The antimicrobial activity of the extracts of these plants were tested and compared against the microorganisms consisting of selected bacteria and yeasts. It was found that they were more effective against bacteria. The best results in antioxidant activity tested by DPPH radical scavenging activity were recorded as 90. 80 % in Malatya St. John' s wort at a concentration of 1000 mu l. The chemical content of the samples of H. perforatum and H. malatyanum plant extracts were determined by GC/MS method and as a result, 14 of the 30 different chemical components identified in both plants showed differences.
