Özet
In this paper, Epilobium angustifolium L. in Turkey was investigated for total phenolics, flavonoids,
and anthocyanin amounts. Furthermore, the ethanol extract of the leafs was evaluated for antioxidant
activities as ABTS, hydroxyl radical scavenging, superoxide radical scavenging, power of reduction,
and bleaching of beta-carotene. The total phenolic and flavonoid contents of the ethanolic extract were
found to be 468,11± 1,53 micrograms of pyrocatechol per milligram of the extract and 103,05 ± 2,36
µg catechin per milligram of the extract, respectively. As the extract concentration increased, the
amount of anthocyanins showed a decrease (17.92±8.08 and 13.56±8.22 for the 1 mg/mL and 2 mg/mL
concentrations, respectively). In the β-carotene bleaching test, higher activity was observed than BHA
( 1.540±0.053 and 1, respectively). The results of the reduction power, hydroxyl radical scavenging,
and ABTS tests gave either very close values or higher than the standards chosen. Superoxide radical
scavenging activity gave a lower value than the Trolox selected as standard. Antioxidant activity of
ethanol extract was found to be 94.22±0.05958 (ABTS), 78.77±0.84099 (hydroxyl radical scavenging)
and 47.86±0.03915 (superoxide radical scavenging). The experimental data indicate that Turkey
Epilobium angustifolium L. ethanol extract can be used pharmacologically
