Abstract :Natural compounds play an important role among antioxidants that protect the human body against oxidative stress. Many plants may have high levels of antioxidant capacity through the compounds they contain. In line with this information, in the current study, we aimed to evaluate the antioxidant properties of Galanthus elwesii Hook.f. In this context, we tested the 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging and metal chelating activities of different concentrations (12.5-400 mg/L) of methanol and water extracts obtained from the bulb part of this plant. A concentration-dependent increase in activity was observed for both extracts. DPPH scavenging (87.10%) and metal chelating (72.99%) activities demonstrated by 400 mg/L concentration applications came to the fore. In addition, it was determined that these data were significantly (p < 0.05) higher than the activity rates revealed by other applications. Considering the IC50 values, low values for DPPH scavenging and metal chelating activities (110.88 mg/L and 132.40 mg/L, respectively) were detected in water extracts. As a result, the importance of G. elwesii among plants that have the potential to be a rich source of antioxidants was revealed in this study.
