In Vitro Biological Activities Of Ranunculus gracilis Clarke Rhizome

R. gracilis rhizomes were picked from Yenice Forests Karabük province in Turkey. Ethanol was chosen for extraction solvent. Disc diffusion method including filamentous and non-filamentous Gram-positive bacteria, Gram-negative yeast strains used to evaluate the antimicrobial activity of extract. DPPH free radical scavenging ferric reducing antioxidant power analysis performed determine activity. The Folin-Ciocalteu determining total phenolic amount AlCl3 flavonoid content extract chosen. Mean diameters inhibition zones (IZD) bacteria found range 8.2 mm 24.45 mm. This value measured as 17.82 18.69 yeasts. calculated 7.08 mg AAE/g IC50 9.097 mg/mL FRAP indicated that 1 gram sample equivalent 4.66 μmol Trolox. ethanol determined 0.414 GAE/g, while 0.68 mgQE/g. analyzed ethanolic demonstrated biological level could be considered significant according obtained results.
