In this study, the antiradikal activity of water and ethanol extracts of Scutellaria orientalis L. subsp. bicolor (Hochst.) Edmondson was evaluated by various antiradical assay, ABTS• (2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) radical scavenging capacity and DPPH• (2,2-diphenyl-1-picrylhydrazyl) radical scavenging capacity. Those various antiradical activities were compared to standard antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and α-tocopherol. The extracts of Scutellaria orientalis showed strong antioxidant activity. The results obtained in the present study indicated that Scutellaria orientalis is a potential source of natural antioxidant.

Bu çaly?mada, Scutellaria orientalis L. subsp. bicolor (Hochst.) Edmondson' in su ve etanol ekstrelerinin antiradikal aktivitesi ABTS (2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) radikal temizleme kapasitesi and DPPH (2,2-diphenyl-1-picrylhydrazyl) radikal temizleme kapasitesi gibi çe?itli antiradikal yöntemler tarafyndan de?erlendirildi. Bu çe?itli antiradikal aktiviteler bütillendirilmi? hidroksianisol (BHA), bütillendirilmi? hidroksitoluen (BHT) ve α-tokoferol gibi standart antioksidanlarla kar?yla?tyryldy. Scutellaria orientalis' in ekstreleri kuvvetli antioksidan aktivite gösterdi. Mevcut çaly?mada alynan sonuçlar Scutellaria orientalis' in do?al antioksidanlaryn potansiyel bir kayna?y oldu?unu gösterdi.
