The present study aimed to evaluate bioactive potential and activities of the methanolic extracts of four selected Dianthus species growing in Bosnia and Herzegovina (Dianthus sylvestris, Dianthus giganteus, Dianthus deltoides, Dianthus petraeus). Aerial parts of investigated Dianthus species were collected at the full flowering stage and used for the analysis. The total phenolic contents and total flavonoid of plant extracts were determined by Folin–Ciocalteau reagent and aluminum chloride calorimetric assay, respectively. DPPH methods was employed to determine the antioxidant potential. The flower methanolic Dianthus deltoides extract showed the highest values of total phenolic content (65,78 mgGAE/gDW) followed by flower methanolic Diantus sylvestris extract (61,76 mgGAE/gDW). A similar trend was observed with the content of total flavonoids, where the methanol extracts of the flower had a higher content compared to the vegetative part (stem and leaf). All examined extracts of all four species of the genus Dianthus showed strong antioxidant properties with a statistically lower antioxidant capacity of the extract of the vegetative part of the species D. deltoides. However, for the same species, the lowest IC50 value was recorded for the flower extract (0.18 mg/ml), i.e. the strongest antioxidant effect. D. deltoides and D. sylvestris extracts showed significant differences between the IC50 values of the flower extract and the extract of the vegetative part of the plant. [ABSTRACT FROM AUTHOR]
