Determination of antioxidant capacities of Salvia Hasankeyfensis Dirmenci, Celep & O.Güner, Stachys Mardinensis (Post) R.R. Mill, Ferulago Bernardii L.Tomkovich & M.Pimenov ve Hymenocrater Bituminosus Fisch. & C.A.Mey.

Antioxidant and antimicrobial activities of ethanol-water extracts of Salvia hasankeyfensis, Ferulago bernardii, Stachys mardinensis, Hymeocrater bituminous plants were determined in vitro. Leaf sections of these 4 plants, which are endemic in the East and Southeast Region, have been used. Antioxidant properties of bikes; The total phenol composition was determined using different antioxidant assays such as determination of total flavonoid composition, FRAP activity, free radical (DPPH) removal activity. The obtained results were compared with tables and graphs. Antibacterial study was performed with Agar Disk Diffusion Method. 0.1mg/ml of each plant extract, 1.2mg/ml, 5mg/ml, 10mg/ml, 20mg/ml were taken and placed in the inoculated petri dishes with bacteria. As a result, in the determination of antioxidant, Stachys Mardinensis plant showed the best activity on ethanol basis and it was determined that Salvia Hasankeyfense plant was on general basis. Hymenocrater Bituminous has the lowest antioxidant effect. DPPH shows the highest activity, alcohol extracts show better activity than water extracts, which may be due to the fact that alcohol can contain more substances.
