Özet

The aim of our study was to evaluate in vitro antioxidant potential of methanolic extracts (ME) of 14 medicinal plants, 8 of which are endemic species of Anatolia. Scavenging activity was tested by 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and the inhibitory effect on lipid peroxidation was examined by the ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods. The obtained results showed significant differences in the antioxidant potential amongst the tested methanolic plant extracts. Among the plant samples, Crataegus microphylla C. Koch, Salvia hypargeia Fisch. & Mey., Cotinus coggygria Scop., Origanum sipyleum L. and Rosa damascena Miller exhibited the highest DPPH scavenging activity. Five extracts (Centaurea nerimaniae S. Kultur, C. coggygria, Scorzonera tomentosa L., R. damascena and Colchicum sanguicolle K.M. Perss) showed strong antioxidant activity in the FTC and TBA tests, with per cent inhibition ranges of 72%-84% and 84%-92%, respectively. The ME of C. coggygria and R. damascena exhibited potent antioxidant activity by the DPPH, FTC and TBA methods.
