In this study, it was determined that total phenolic and flavonoid substance amounts and antioxidant capacity of methanol extracts obtained from leaves (Y) and buds (T) of mistletoe (V. album ssp. Austriacum) collected from Northeast Anatolian Yellow Pine forests (Pinus sylvestris L). The amount of total phenolic substance was determined as 19.55 ±4.68 mg GAE/g in Y and 16.88 ±2.77 mg GAE/g in T, while amount of total flavonoid substance 17.56 ±2.53 mg QE/g in Y and 17.17 ±3.29 mg QE/g in T. IC50 values were calculated as 476.26 ±22.54 μg/mL in Y and 778.57±25.61 μg/mL in T. In addition, the reducing antioxidant powers of Fe3+-Fe2+ were calculated as 303.00 ±1.73 μg AAE/mL in Y and 307.01±1.05 μg AAE/mL in T, equivalent to ascorbic acid. As a result, it was seen that mistletoe which is considered harmful for yellow pines, has antioxidant properties. It has been concluded that the evaluation of mistletoe collected during the struggle with mistletoe as a natural antioxidant source may contribute economically.
