Examination of Secondary Metabolites and Antioxidant Capacity of Anthyllis Vulneraria, Fuchsia sp., Galium Mollugo and Veronica Beccabunga
Anthyllis vulneraria L., Fuchsia sp., Galium mollugo L., and Veronica beccabunga L. were selected to analyse the phenolic content and the antioxidant activity by ferric ion reducing antioxidant power (FRAP) and trolox equivalent antioxidant capacity (TEAC) assays. The highest polyphenol, tannin, and flavonoid contents were measured in Fuchsia species (7.40 ± 0.8, 5.62 ± 0.7 and 0.72 ± 0.1 g/100 g dry weight), while the lowest values were detected in Anthyllis vulneraria (0.68 ± 0.02, 0.17 ± 0.03 and 0.45 ± 0.01 g/100 g dry weight) and Galium mollugo (1.77 ± 0.05, 0.49 ± 0.04 and 0.16 ± 0.06 g/100 g dry weight). The leaf extract of Fuchsia sp. had the highest, while the herb of A. vulneraria had the lowest antioxidant effect measured by both methods, which is probably related to total polyphenol, tannin, and flavonoid contents.
